Description

This filter hook allows developers to modify the content of a generated quiz certificate before it's saved or displayed. Developers can use this hook to dynamically alter text, add custom information, or even apply regular expressions to the certificate's content. The hook provides access to the current certificate content, user ID, quiz ID, and course ID for targeted modifications.

Usage

add_filter( 'uo_generate_quiz_certificate_content', 'your_function_name', 10, 2 );

Parameters

$cert_content (mixed)
- **$user** `mixed`
$quiz_id (mixed)
- **$course_id** `mixed`

Return Value

The filtered value.

Examples

// Example function to add a custom message to the certificate content based on quiz score.
function custom_certificate_message( $cert_content, $user, $quiz_id, $course_id ) {

    // We need to fetch the quiz score to determine if we should add a custom message.
    // This is a placeholder. In a real scenario, you'd likely use a plugin's API
    // or a custom database query to get the user's score for this specific quiz.
    // For demonstration, let's assume we can retrieve a score.
    $user_quiz_score = get_user_quiz_score( $user->ID, $quiz_id ); // This function needs to be defined or replaced with actual logic.

    // Let's assume a score of 90 or above is considered excellent.
    if ( $user_quiz_score >= 90 ) {
        $custom_message = '<p style="text-align:center; font-style:italic;">Congratulations on your outstanding performance!</p>';
        // Append the custom message to the existing certificate content.
        // We'll assume $cert_content is a string or HTML.
        $cert_content .= $custom_message;
    } elseif ( $user_quiz_score >= 70 ) {
        $custom_message = '<p style="text-align:center; font-style:italic;">Well done on completing this quiz!</p>';
        $cert_content .= $custom_message;
    }

    // Return the modified certificate content.
    return $cert_content;
}
add_filter( 'uo_generate_quiz_certificate_content', 'custom_certificate_message', 10, 4 );

// Placeholder function for getting user's quiz score.
// In a real application, this would interact with your LMS plugin's data.
function get_user_quiz_score( $user_id, $quiz_id ) {
    // This is a mock function. Replace with actual logic to fetch the score.
    // For example, if using a popular LMS plugin, you might have a function like:
    // return TutorLMS()->quiz->get_quiz_final_score( $quiz_id, $user_id );
    // Or retrieve from custom post meta or user meta.

    // For this example, we'll return a random score for demonstration.
    return rand(50, 100);
}

Placement
