Hi @juanmtorrijos

I believe you can check if a student has a certificate or not like this:

// Get the posted data
$posted_course = $_POST['acf']['field_1234567890abc'];
$student_name = $_POST['acf']['field_abcdefghij123'];

// Check if a certificate with the same name and course exsists or not
$the_posts = get_posts(array(
    'post_type' => 'certificate',
    'meta_query' => array(
        'relation' => 'AND',
        array(
            'key' => 'student_name_field',
            'value' => $student_name
            'compare' => '=',
        ),
        array(
            'key' => 'course_field',
            'value' => $posted_course,
            'compare' => '=',
        ),
    ),
));

if( $the_post ){
    // The student has taken the course. Give a warning here
} else {
    // The student hasn't taken the course yet. Process it here.
}

Where ‘field_1234567890abc’ and ‘field_abcdefghij123’ is the field keys.

I hope this helps 🙂
