add_filter( 'uo_quiz_certificate_http_url', 'your_function_name', 10, 1 );

Parameters

$file_name (mixed)
This parameter contains the file name of the generated certificate.

Return Value

The filtered value.

Examples

<?php
/**
 * Example of how to use the 'uo_quiz_certificate_http_url' filter to modify the certificate URL.
 * This example appends a query parameter with the current timestamp to the URL,
 * potentially for cache-busting purposes or to indicate a fresh download.
 *
 * @param string $http_link_to_file The original HTTP URL to the certificate PDF.
 * @return string The modified HTTP URL to the certificate PDF.
 */
add_filter( 'uo_quiz_certificate_http_url', function( $http_link_to_file ) {
    // Get the current timestamp.
    $current_timestamp = time();

    // Append the timestamp as a query parameter for cache busting.
    // This ensures that if the certificate is regenerated, a new URL is provided.
    $modified_url = add_query_arg( 't', $current_timestamp, $http_link_to_file );

    return $modified_url;
}, 10, 1 ); // Priority 10, accepts 1 argument.
