[CoursePress] Include course enrollment date in course certificate

Would it be possible to include the course enrollment date in the course completion certificate?

I know that this is a custom development request as currently, the only macros available to use are:

COURSE_NAME, COURSE_SUB_TITLE, COURSE_OVERVIEW, COURSE_UNIT_LIST, DOWNLOAD_CERTIFICATE_LINK, DOWNLOAD_CERTIFICATE_BUTTON, STUDENT_WORKBOOK

But if someone knows how this could be achieved, we’d really appreciate the help. Thanks!

    Hi carl ,

    In order to add the enrollment date macro in the certificate, you can add the following snippet in a mu-plugin:

    function wpmudev_cp_custom_certificate_vars( $vars ) {
    

    
if ( ! isset( $_REQUEST['c'] ) || ! isset( $_REQUEST['u'] ) ) {
    
return $vars;
    
}
    

    
$course_id                  = (int) $_REQUEST['c'];
    
$student_id                 = (int) $_REQUEST['u'];
    
$date_format                = get_option( 'date_format', 'Y-m-d' ) . ' ' . get_option( 'time_format', 'H:i:s' );
    
$enrollment_date            = date(
    
$date_format,
    
strtotime( CoursePress_Data_Course::student_enrolled( $student_id, $course_id ) )
    
);
    

    
$vars['ENROLLMENT_DATE']    = $enrollment_date;
    

    
return $vars;
    
}
    

    
add_filter( 'coursepress_basic_certificate_vars', 'wpmudev_cp_custom_certificate_vars', 20 );

    and use the ENROLLMENT_DATE macro in the certificate content.

    As in your question you included some macro’s from the Completion Page, I’m including a snippet that you can use to add the same macro there too:

    add_filter( 'coursepress_virtual_page', function( $vp_args, $cp ){
    

    
if (
    
! isset( $vp_args['ID'] ) ||
    
! isset( $vp_args['content'] ) )
    
{
    
return $vp_args;
    
}
    

    
$course_id = (int) $vp_args['ID'];
    
$student_id = isset( $cp->student_id ) ? (int) $cp->student_id : ( is_user_logged_in() ? get_current_user_id() : false );
    

    
if ( ! $student_id ) {
    
return $vp_args;
    
}
    

    
$date_format = get_option( 'date_format', 'Y-m-d' ) . ' ' . get_option( 'time_format', 'H:i:s' );
    

    
$enrollment_date = isset( $cp->is_enrolled ) ? date( $date_format, strtotime( $cp->is_enrolled ) ) : false;
    

    
if ( ! $enrollment_date ) {
    
$enrollment_date = date(
    
$date_format,
    
strtotime( CoursePress_Data_Course::student_enrolled( $student_id, $course_id ) )
    
);
    
}
    

    
$replacements = array(
    
'ENROLLMENT_DATE' => $enrollment_date
    
);
    

    
$vp_args['content'] = str_replace( array_keys( $replacements ), array_values( $replacements ), $vp_args['content'] );
    

    
return $vp_args;
    

    
}, 20 ,2 );
