Using the API to Fetch Weather Data on a WordPress Website is a great real-time weather API you can use to fetch weather information and display it on your website or application. Here’s how I am using the API to display my local weather information on my WordPress website.

Firstly, I decided I didn’t want to have to hit the API every time a user visits my page. Since I am only display today’s average condition, high and low temperatures, and sunrise and sunset data—all data which isn’t going to change from minute to minute—there is no need to hit the API on every page load. And, if you have a website with a large amount of traffic, hitting the API that frequently might make you go over your Quota.

Instead, I’m just hitting the API hourly, at most, and saving the data to my database. My PHP then draws that data from my database directly. Hourly is still overkill in my use case, but still well within limits.

First I set up an ACF (Advanced Custom Fields) options page for my weather data, and included fields for the following:

  1. Last Weather Fetch Date
  2. Last Weather Fetch Hour
  3. Weather JSON
  4. Weather Fetch Error
  5. Weather Coordinates
Weather Options Page

All of these fields will be automatically populated by my PHP weather fetching function except for the weather coordinates—which is the latitude and longitude of the location I want to get my weather data for. You can easily get these via Google Maps by right-clicking any location on the map and copying the coordinates.

Next, I wrote the function to fetch the weather:

 * Function - Fetch Weather
function fetch_weather($current_date, $current_hour)

	$weather_coordinates = get_field('weather_coordinates', 'option');
	// API endpoint URL
	if ($weather_coordinates) {
		$api_url = '' . $weather_coordinates . '&apikey=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
	} else {
		$api_url = ', -118.45199326849152&apikey=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

	// Make the API request
	$response = wp_remote_get($api_url);

	// Check if the request was successful
	if (is_wp_error($response)) {
		// Handle the error
		// echo 'Error: ' . $response->get_error_message();
		$weather_fetch_error_field = get_field('weather_fetch_error', 'option');

		if ($weather_fetch_error_field) {
			delete_field('weather_fetch_error', 'option');

		update_field('weather_fetch_error', $response->get_error_messages(), 'option');
	} else {
		// The request was successful, and $response contains the API response
		$body = wp_remote_retrieve_body($response);

		// Now you can work with the API response, for example, decode JSON
		$data = json_decode($body, true);

		// Save the data to the "Weather JSON" option field
		update_field('weather_json', $body, 'option');
		update_field('last_weather_fetch_date', $current_date, 'option');
		update_field('last_weather_fetch_hour', $current_hour, 'option');

There is another function that will call fetch_weather() only if it’s needed (if the weather has not been updated within the last hour) and return the weather as JSON. If the weather is current, then it just gets the weather that is already saved in my database.

function get_weather_json()
    $current_date = date('Ymd');
    $current_hour = date('G');
    $last_weather_fetch_date = get_field('last_weather_fetch_date', 'option');
    $last_weather_fetch_hour = get_field('last_weather_fetch_hour', 'option');

    // Fetch new data, if necessary
    if (!$last_weather_fetch_date || $last_weather_fetch_date != $current_date || !$last_weather_fetch_hour || $current_hour > $last_weather_fetch_hour) {
        fetch_weather($current_date, $current_hour);

    // Display
    $weather_json = get_field('weather_json', 'option');

    return $weather_json;

Next, I created a function to display the weather data that gets saved to my database.

 * Function - Display Weather Card
function display_weather_card($weather_json)
    $data = json_decode($weather_json, true);

    $minute_index = 0;
    $day_index = 0;

    $current_temperature_fahrenheight = number_format(($data['timelines']['minutely'][$minute_index]['values']['temperature'] * 9 / 5) + 32, 0);

    $today_high_temperature_fahrenheight = number_format(($data['timelines']['daily'][$day_index]['values']['temperatureMax'] * 9 / 5) + 32, 0);

    $today_low_temperature_fahrenheight = number_format(($data['timelines']['daily'][$day_index]['values']['temperatureMin'] * 9 / 5) + 32, 0);

    $today_rain_accumulation_sum = $data['timelines']['daily'][$day_index]['values']['rainAccumulationSum'];

    $today_cloud_cover_avg = $data['timelines']['daily'][$day_index]['values']['cloudCoverAvg'];

    $today_snow_accumulation_avg = $data['timelines']['daily'][$day_index]['values']['snowAccumulationAvg'];

    // Rain
    $will_rain = false;
    if ($today_rain_accumulation_sum >= 1) {
        $will_rain = true;

    $will_snow = false;
    if ($today_snow_accumulation_avg >= 1) {
        $will_snow = true;

    // Cloudy
    $cloudy = false;
    if ($today_cloud_cover_avg >= 33) {
        $cloudy = true;

    $condition = 'Sunny';
    $weather_icon = '<i class="fa-light fa-sun"></i>';

    if ($cloudy) {
        $condition = 'Cloudy';
        $weather_icon = '<i class="fa-light fa-clouds"></i>';
    if ($will_rain) {
        $condition = 'Rainy';
        $weather_icon = '<i class="fa-light fa-cloud-rain"></i>';
    if ($will_snow) {
        $condition = 'Snowy';
        $weather_icon = '<i class="fa-light fa-cloud-snow"></i>';

    // Sunsrise & Sunset times
    $today_sunrise_time = $data['timelines']['daily'][$day_index]['values']['sunriseTime'];
    $today_sunset_time = $data['timelines']['daily'][$day_index]['values']['sunsetTime'];

    // Create a DateTime object from the string
    $today_sunrise_time = new DateTime($today_sunrise_time);
    $today_sunset_time = new DateTime($today_sunset_time);

    // Set the timezone to Los Angeles
    $losAngelesTimezone = new DateTimeZone('America/Los_Angeles');

    // Format the time in 12-hour format
    $today_sunrise_time = $today_sunrise_time->format('g:i A');
    $today_sunset_time = $today_sunset_time->format('g:i A');

    <div class="cards addfade">
        <div class="card decoration-1">
            <div class="columns">
                <div class="column weather-icon">
                        <?php echo $weather_icon; ?>
                <div class="column current-temperature">
                        <?php echo $current_temperature_fahrenheight . '°F'; ?>
                <div class="column high-low-temps">
                        <span><i class="fa-solid fa-temperature-full"></i><i class="fa-solid fa-arrow-up"></i></span>
                            <?php echo $today_high_temperature_fahrenheight . '°F'; ?>
                        <span><i class="fa-solid fa-temperature-quarter"></i><i class="fa-solid fa-arrow-down"></i></span>
                            <?php echo $today_low_temperature_fahrenheight . '°F'; ?>
                <div class="column sunrise-sunset-times">
                        <span><i class="fa-solid fa-sunrise"></i></span>
                            <?php echo $today_sunrise_time; ?>
                        <span><i class="fa-solid fa-sunset"></i></span>
                            <?php echo $today_sunset_time; ?>

It also uses FontAwesome icons to display the general condition of the day, depending on the weather.

Lastly, my custom weather WordPress block calls the appropriate functions and displays the weather.


And there you have it!

Optimizing WordPress Image Scaling for a Better Performing Website

In my previous post discussing the importance of serving appropriately scaled images on your web pages, let’s delve into how WordPress handles image scaling.

The Problem

When you upload an image to your WordPress media library, the default behavior is for WordPress to automatically generate three downscaled versions of that image. For example, if you upload an image sized 2048 x 1536 pixels, WordPress will create a thumbnail (150 x 150 pixels), a medium-sized version (maximum width and height of 300 pixels), and a large version (maximum width and height of 1024 pixels).

Now, consider a scenario where you have a card on your site that is 300 pixels wide, and you need to place an image in it. While you could use the original full-size image, it’s not optimal because it will only be displayed at 300 pixels wide, resulting in unnecessary resource consumption. Instead, this is an ideal situation to utilize the medium-scaled image size.

However, if you have a card that is 600 pixels wide and you want to use an image that spans the entire width of the card, the medium image size is inadequate. Enlarging it to fill 600 pixels will make it appear pixelated. The next available scaled image size, large (1024 pixels), is too large for the container, although it’s still better than using the original full-size image.

The Solution

To address this, you can generate a new scaled image size tailored to your specific needs. Here’s how you can do it:

In your functions.php file, include the following code:

 * Register new image sizes
add_image_size('image_size_600', 600, 600);

The first parameter is the name you choose for your new scaled image, the second parameter is the image width in pixels, the third parameter is the image height in pixels, and the fourth parameter (not used in the example above) is for image cropping.

For more details about this function, refer to WordPress add_image_size function.

Once you’ve added your new custom-scaled image size, you can use a plugin like Regenerate Thumbnails to process the images in your media library and create new images of that scale. Subsequently added images to your media library will be automatically scaled.

Now, you can serve appropriately sized images according to your site design requirements.


Keep in mind that each time you add an image to your media library, three additional versions are created by default. Introducing new image sizes means more versions for each image stored on your server, potentially bloating the size of your media library. Therefore, use this feature strategically to avoid unnecessary increases in server storage.

The Importance of Properly-Sized Images on Your WordPress Website

When building a website, many people focus on the design, content, and functionality, but overlook the importance of image optimization. Not only can images be a significant factor in the load time of a website, but improperly sized images can also negatively impact user experience, SEO, and even website performance.

In this article, we’ll explore how to properly size and serve images on a WordPress website, as well as why it’s crucial to do so.

Why Image Optimization Matters

Before diving into the technical aspects of image optimization, it’s important to understand why it matters.

First and foremost, image optimization affects website load time. Large, high-resolution images can take a long time to load, especially on slower internet connections. This can lead to a poor user experience, with visitors abandoning the site before it fully loads.

Additionally, search engines like Google take website speed into account when ranking pages in search results. A slow website can negatively impact your SEO efforts and make it harder for potential customers to find you online.

Finally, improperly sized images can also impact website performance. If you’re serving large images that are scaled down with CSS, the user’s device still needs to download the full-size image, which wastes bandwidth and slows down the website.

How to Properly Size and Serve Images on WordPress

Now that we understand the importance of image optimization, let’s look at how to properly size and serve images on a WordPress website.

  1. Determine the Correct Image Size

The first step in optimizing your images is to determine the correct size. This will depend on the size of the container where the image will be displayed. For example, if your website’s content area is 800 pixels wide, you don’t want to use an image that’s 2000 pixels wide.

To determine the correct size, you can use a tool like Google’s PageSpeed Insights or GTmetrix. These tools will analyze your website and provide recommendations for optimizing your images, including suggestions for the correct image sizes.

  1. Compress Your Images

Once you have determined the correct size for your images, the next step is to compress them. Compression reduces the file size of the image without significantly reducing the quality.

There are several tools you can use to compress your images, including Photoshop, GIMP, and online tools like TinyPNG or

  1. Use WordPress Plugins

WordPress offers several plugins that can help with image optimization. Some popular options include:

  • WP Smush: This plugin automatically compresses images as they are uploaded to your website.
  • EWWW Image Optimizer: This plugin can compress and optimize your images in bulk.
  • Lazy Load: This plugin delays the loading of images until they are actually visible on the page, which can improve website speed.
  1. Serve Images in the Correct Format

Finally, it’s important to serve your images in the correct format. There are several image formats to choose from, including JPEG, PNG, and GIF.

JPEG is the most common format for photographs, as it offers high-quality images with a small file size. PNG is better for images with transparent backgrounds, while GIF is ideal for animated images.

When serving images on your website, it’s important to choose the appropriate format for the type of image you’re using. This will ensure that your images are optimized for both quality and speed.


Properly sizing and serving images on a WordPress website is essential for optimizing website speed, improving user experience, and boosting SEO efforts. By determining the correct image size, compressing images, using WordPress plugins, and serving images in the correct format, you can ensure that your website loads quickly and provides a seamless experience for visitors.

Remember, every little bit counts when it comes to website optimization. Taking the time to properly optimize your images can make a big difference in your website’s performance and ultimately lead to a better user experience for your visitors.

By following the steps outlined in this article, you can ensure that your WordPress website is serving properly sized images that are optimized for speed and quality. Additionally, you can take advantage of WordPress plugins and online tools to simplify the process and save time.

Remember to keep image optimization in mind as you continue to build and update your website. It’s a crucial component of website design and can have a big impact on your overall success online.

JavaScript: Declaring Variables with “let” vs. “const”

JavaScript has two keywords for declaring variables: “let” and “const”. Both keywords have similar functionality, but there are some differences between them that are important to understand.

“Let” allows you to declare a variable whose value can be changed later in the code. For example, let’s say you want to declare a variable named “x” and assign it a value of 5. You would use the following code:

let x = 5;

Later in the code, you can change the value of “x” by simply assigning a new value to it:

x = 10;

“Const” is similar to “let”, but it declares a variable that cannot be reassigned. If you try to change the value of a “const” variable, you will get an error. For example, the following code would result in an error:

const y = 5; y = 10; // Error: Assignment to constant variable.

It’s important to note that the value of a “const” variable can still be changed if it’s an object or an array. For example:

const z = {}; = 'John'; // This is allowed. z = {}; // Error: Assignment to constant variable.

So, when should you use “let” and when should you use “const”? Here are a few guidelines:

  • Use “const” when you want to declare a variable that will never change.
  • Use “let” when you want to declare a variable that will change.
  • Use “const” when you want to make sure that a variable can’t be reassigned.
  • Use “let” when you want to declare a variable in a loop, as the value of the variable needs to change with each iteration.

In conclusion, the choice between “let” and “const” depends on the specific use case and the intended behavior of the variable. It’s important to understand the differences between these two keywords, as using the wrong keyword can lead to unexpected results or errors in your code. By using “const” when appropriate and “let” when needed, you can write cleaner and more maintainable code.

CSS Variables vs Sass Variables

CSS and Sass are both stylesheet languages used for styling web pages. They both have the ability to store values in variables and reuse them throughout the stylesheet. But there is a difference between the way CSS variables and Sass variables work, and in this article, we will explore the similarities and differences between the two.

CSS Variables

CSS Variables, also known as CSS Custom Properties, are a feature introduced in CSS3. They are defined using the “–” syntax, for example:

:root {   --primary-color: blue; }  h1 {   color: var(--primary-color); } 

CSS variables are scoped to the element where they are declared and can be overridden in descendants. They can be dynamically updated using JavaScript, which opens up new possibilities for dynamic styling on the web.

Sass Variables

Sass is a preprocessor for CSS, it adds additional features to CSS such as variables, nesting, and mixins. Sass variables are declared using the “$” symbol, for example:

$primary-color: blue;  h1 {   color: $primary-color; } 

Sass variables have the same functionality as CSS variables, but they have some additional features. Sass variables can be assigned to expressions, which allows you to perform calculations and generate complex styles dynamically.

$width: 500px; $height: $width / 2;  .container {   width: $width;   height: $height; } 

Another advantage of Sass variables is that they can be organized into maps, which allows you to group related variables and make your code more readable.

$colors: (   primary: blue,   secondary: green );  h1 {   color: map-get($colors, primary); } 

Differences between CSS and Sass Variables

  1. Scoping: CSS variables are scoped to the element where they are declared, while Sass variables are global and can be accessed from any part of the stylesheet.
  2. Dynamic updates: CSS variables can be updated dynamically with JavaScript, while Sass variables cannot.
  3. Expressions: Sass variables can be assigned to expressions, which allow you to perform calculations and generate complex styles dynamically, while CSS variables cannot.
  4. Maps: Sass variables can be organized into maps, making it easier to group related variables and make your code more readable, while CSS variables do not have this feature.


In conclusion, both CSS and Sass variables serve the same purpose, which is to store values and reuse them throughout the stylesheet. However, Sass variables offer additional features such as expressions and maps, which make them a better choice for complex stylesheets. On the other hand, CSS variables are scoped to the element where they are declared and can be updated dynamically with JavaScript, making them a better choice for dynamic styling on the web. Choose the right tool for the job, and you’ll have an easier time styling your website.

Run PHP Function When Updating WordPress ACF Options Page

I needed to run a custom PHP function that updates custom fields (using Advanced Custom Fields) attached to users when an admin clicks “update” on a back-end options page. The way I did this was using the acf/save_post action.

By itself, the function would be triggered when updating any options page. I didn’t want this. I only wanted the function to run when updating one specific options page. To fix this, I wrapped the function’s code in an if statement that checks if get_current_screen() was equal to my options page.

add_action('acf/save_post', 'update_users_reporting_log'); function update_users_reporting_log() {     $screen = get_current_screen();     if (strpos($screen->id, "reported-content") == true) {         // Function code here:               endif;     } }

strpost() will check to see if a particular string occurs inside another. Actually, it will find the position of the occurance, but I didn’t care about the position, only if it did occur. And the string I was checking inside of is the return of get_current_screen(). The name of my options page is “reported-content”.

Now, when a user clicks the “update” button on that particular options page, my custom function will run, updating custom fields elsewhere on the site.

The Power of Custom Fields

What Are Custom Fields?

Custom fields allow you to easily add custom data to posts, pages, or other areas of the database. Where they really start to shine is using them in conjunction with custom post types.

For example, on my IMPbDb website, I use three custom post types: movies, tv shows, and pinball machines. For the pinball machine post type, I have attached several custom fields: game title, manufacturer, year, machine type, number produced, etc.

Some of the custom fields on my pinball machine custom post type.

You can then write your page template to display the data from your custom fields.

Custom fields data displayed on page.

You can even create forms on your site that allow for users to add or edit data from custom fields. It’s quite a powerful tool.

Advanced Custom Fields

The Advanced Custom Fields plugin makes it very easy to add custom fields to just about anywhere on your WordPress site.

For example, on this website, I use ACF to add an excerpt WYSIWYG editor to all my posts. I then show that excerpt when looping my posts on the home page or archive page. You might wonder why I do this when WordPress posts already have an excerpt field. It’s because the WordPress excerpt field is a simple text box, where if I make it a WYSIWYG editor, I can write HTML code in it to do much more advance things. Try creating a hyperlink in the standard WordPress excerpt field and you’ll see what I mean.

I’ve also used ACF on another site, to add a list of followed users to a user’s profile. It does this through the use of a repeater field which can store all sorts of information, but in this case, just a user ID. I can then loop through that custom field to generate a list of any users a particular user follows. Think of it like following another account on Twitter. You probably follow many, you can access a list of them. This allows me to do the same thing.

Custom Field Types

Advanced Custom Fields has field types for just about anything you would need.

  • Range
  • Text
  • Text area
  • Button group
  • Checkbox
  • Radio button
  • Select
  • True / false
  • File
  • Gallery
  • Image
  • oEmbed
  • WYSIWYG editor
  • Color picker
  • Date picker
  • Date time picker
  • Google maps
  • Time picker
  • Accordion

UpdraftPlus – Website Backup and Migration Plugin

What Is UpdraftPlus?

UpdraftPlus’ main backup controls.

UpdraftPlus is a WordPress plugin that makes it super simple to schedule automatic backups of your website. You can easily restore all or parts of the website from backups—for instance, maybe you’ve added or changed a plugin that broke your site, you can restore just the plugins to revert your site back to a working state. Same goes with themes, uploads, the database, or the WordPress core.

Backup Location Options

The plugin allows you to backup your files to a large variety of different locations. For the most part, I use my dropbox account for backups and it has worked flawlessly for me over the years.

UpdraftPlus’ remote backup locations.

Scheduling Automatic Backups

You can set the plugin to automatically generate backups of your files and database separately, and retain only a set number of backups so that your backup location never runs out of space.

If you’re looking for a plugin to do any of these tasks, give UpdraftPlus a try and see if it will meet your needs.

Audio File Types: Which to Use for Podcasting and Why

What are some various popular audio file types, how are they different, and which ones are the best to use for podcasting? How should you record your podcast?

Audio File Types for Podcasts

Although there are many different audio file types, there are two distinct categories that will help us decide when and why to use those in one group verses those in the other. Those are lossless and lossy file types.


A lossless file type is one that allows for the data to perfectly reconstructed. There is no dataloss when saving to a lossless file type. For this reason, and for optimum quality, all recording and editing should be done using lossless file types. A commonly used lossless file type is a .wav file. The only downside to lossless file types is that they are much larger than lossy types.


A lossy file type is a more highly compressed file type. However, this means that when the audio is reconstructed, it is really only an approximation of the original—unlike with a lossless file type where it is a perfect reconstruction. A commonly used lossy file type is a .MP3 file. The upside to lossy file types is that they are much smaller than lossless types.

Keep Lossy File Saves to a Minimum

Each time you save or manipulate a lossy file type, the data is re-transcoded and compressed. Essentially, you get a compression of a compression of a compression, and so on. Each time, more data is lost and the quality reduced a little more. For this reason, from recording all the way through the final edit, you should ideally be working only with lossless file types. The only time you should save to a lossy file type is when you are going to upload a final cut of your podcast to your server—or if you want to share a cut or piece of audio for someone else to listen to, but you should not go back and further edit that file. Go back to the lossless file to make further edits.

File Types Summary

In summary, when recording and editing, you should use only lossless file types, like a .wav file. When releasing an episode, use a lossy file type.

Having your podcast edited by a professional?

Send them the lossless file. In return, you should get a finalized lossy MP3 of your episode. You should also request a copy of the final lossless file and store it someplace safe.

Keep Your Lossless Files, Just in Case

Even though the finished episode will be uploaded as a lossy MP3, it’s a good idea to hold onto the lossless files, just in case you might ever need to go back to the original source material for some reason—maybe to make further edits, to pull sound bites from a prior episode, or to re-save the audio to a different file type. It’s always nice to have that original lossless copy.
