Course Builder Custom Fields

Registering Custom Fields

• masterstudy_lms_course_custom_fields

• masterstudy_lms_lesson_custom_fields

• masterstudy_lms_quiz_custom_fields

Example:

function masterstudy_lms_custom_fields( $custom_fields ) {
	$quiz_custom_fields = array(
		array(
			'type'    => 'text',
			'name'    => 'my-text-field',
			'label'   => __( 'Text field', 'masterstudy-lms-learning-management-system' ),
		),
		...
	);

	return array_merge( $custom_fields, $quiz_custom_fields );
}

add_filter( 'masterstudy_lms_course_custom_fields', 'masterstudy_lms_custom_fields' );

How to filter custom fields before sending to Course Builder

Course Builder Custom Fields could be filtered before sending to Course Builder using masterstudy_lms_course_builder_custom_fields filter.

Example:

function masterstudy_lms_filter_custom_fields( $custom_fields, $post_id ) {
  ... // Here Custom Fields could be manipulated 
  
  return $custom_fields;
}

add_filter( 'masterstudy_lms_course_builder_custom_fields', 'masterstudy_lms_filter_custom_fields', 10, 2 );

Processing Input Data

All input data will be automatically saved to post_meta. Additionally, data can be used with action:

// Some codedo_action( 'masterstudy_lms_custom_fields_updated', int $post_id, array $data )

Parameters:

• $post_id int Course, Lesson, or Quiz Post ID.

• $data array key => value array of Custom Fields

Example:

function masterstudy_lms_after_custom_fields_updated( $post_id, $data ) {
  ... // Here is your code 
}

add_filter( 'masterstudy_lms_custom_fields_updated', 'masterstudy_lms_after_custom_fields_updated', 10, 2 );
