How to Use AJAX in a WordPress Shortcode?

Implementing AJAX with a Shortcode

PHP:

The PHP code for the shortcode should include the following:

function random_quote( $atts ) {
    // Extract shortcode attributes
    extract( shortcode_atts( array(
        'path' => get_template_directory_uri() . '/quotes.txt' // Default path
    ), $atts ) );

    // Retrieve quotes from file
    $array = file( $path );
    $r = rand( 0, count($array) - 1 );

    // Render shortcode output
    $output = '<div>

jQuery:

Handle the button click and perform the AJAX request:

jQuery('#newquote').click( function() {
    // Send AJAX request to retrieve a new quote
    $.ajax({
        type: 'POST',
        url: ajaxParams.themeURI+'js/ajax-load-quote.php',
        data: { file_path: ajaxParams.filePath },
        beforeSend: function() {
            ajaxLoadingScreen(true,'#randomquotes');
        },
        success: function(data) {
            // Replace old quote with new one
            jQuery('#randomquotes').find('p').remove();
            jQuery('#randomquotes').prepend(data);
        },
        complete: function() {
            ajaxLoadingScreen(false,'#randomquotes');
        }
    });
    return false;
});

How to Use AJAX in WordPress Shortcodes

1. Create PHP File: Establish a communication point between JS and PHP (e.g., ajax-load-quote.php).
2. Configure Shortcode: Write the shortcode to generate the necessary HTML and JS/AJAX integrations.
3. Load Necessary Scripts: Enqueue the required JS file in functions.php (e.g., wp_enqueue_script).
4. AJAX Call in JavaScript: Use jQuery, XHR, or similar to send AJAX requests from JS.
5. Process AJAX Request in PHP: Handle the data, perform necessary operations, and return the modified content.
6. Update View in JS: Update the HTML based on the response from the server-side AJAX request.
