How to fetch a custom part of a URL in WordPress using AJAX?

1. Enqueue jQuery in your theme's functions.php file:

1
2
3
4

function add_custom_jquery() {
    wp_enqueue_script('jquery');
}
add_action('wp_enqueue_scripts', 'add_custom_jquery');

1. Create a custom JavaScript file to handle the AJAX request, for example, custom-ajax.js:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

jQuery(document).ready(function($) {
    $('#fetch-custom-url').click(function() {
        var customUrl = 'your-custom-url-here';
        $.ajax({
            url: ajaxurl,
            type: 'GET',
            data: { action: 'fetch_custom_url', customUrl: customUrl },
            success: function(response) {
                console.log(response);
            }
        });
    });
});

1. In your functions.php file, add the AJAX action to fetch the custom part of the URL:

1
2
3
4
5

add_action('wp_ajax_fetch_custom_url', 'fetch_custom_url');

function fetch_custom_url() {
    $customUrl = $_GET['customUrl'];
    // Process the custom URL and return the result
    $customData = 'Your custom data here';
    echo $customData;
    wp_die();
}

1. Print the button in your WordPress template file to trigger the AJAX request:

1

<button id="fetch-custom-url">Fetch Custom URL</button>

Now, when you click the button with the ID 'fetch-custom-url', the AJAX request will be triggered and the custom part of the URL will be fetched and displayed in the browser console. You can then process this data as needed in your AJAX success function.

What is the way to display a specific part of a URL in WordPress widgets?

1. Get the URL of the current page:

1

$current_url = home_url(add_query_arg(array(), $wp->request));

1. Display a specific part of the URL (for example, the page slug):

1

$url_parts = parse_url($current_url);
$path = $url_parts['path'];
$slug = trim(parse_url($current_url, PHP_URL_PATH), '/');

What is the best way to reference a custom section of a URL in WordPress?

The best way to reference a custom section of a URL in WordPress is by using the add_rewrite_rule() function to create a custom URL structure for your specific needs. Here's an example of how to reference a custom section of a URL in WordPress:
