Introduction to the site_icon_url() function in WordPress
The site_icon_url() function is one of the built-in functions in WordPress that allows us to easily retrieve our site's icon. You may have encountered the same task while working with WordPress by using the site icon feature. This icon, which is usually displayed in the browser's tab or next to the page title, helps in identifying your site more easily.
In the past, setting the site icon could be somewhat difficult, but with this function, this task is easily accomplished. By using the site_icon_url() function, you can retrieve the URL of your site’s icon and use it in your templates or styles.
Just keep in mind that for using this function, the icon must have been set beforehand in the site's customization options. This function assists you in accessing your site’s icon without the need for additional coding.
Now let’s look at a simple example of how to use this function. This code will demonstrate how you can retrieve the URL of your site’s icon in the following format. Here’s an example of the code:
<?php
if ( function_exists( 'site_icon_url' ) ) {
$site_icon_url = site_icon_url();
echo '<link rel="icon" href="$site_icon_url" />';
}
?>Description of the code
Now let’s examine this code line by line:
1. <?php
This line indicates that we are writing PHP code.
2. if ( function_exists( 'site_icon_url' ) ) {
With this statement, we check if the
site_icon_url function is accessible or not.3. $site_icon_url = site_icon_url();
Here, we retrieve the URL of the site icon using the function and store it in a variable.
4. echo '<link rel="icon" href="$site_icon_url" />';
Finally, we print a
<link> tag to output the site icon URL in the header so that the browser can recognize it.
