Active Callback

The active_callback can be use to set if field will be display under a condition. For more information you can read Customizer APIs.

Example

In this example the text field will be display if toggle is equal to true.

/**
 * Creating a toggle field
 */
Yano::field( 'toggle', [
   'id'          => 'toggledb1c',
   'label'       => 'Do you want to show text field ?',
   'description' => 'If you want to display the text.',
   'section'     => 'section_id',
   'priority'    => 1
] );

/**
 * Creating a text field
 *
 * if the return value of the function in active_callback 
 * is true then text field will display else it will hide.
 */
Yano::field( 'text', [
   'id'              => 'textdb1c',
   'label'           => 'Text',
   'section'         => 'active',
   'priority'        => 2,
   'active_callback' => function() {
      // condition if the value
      // of toggle is equal to true
      if( get_theme_mod( 'toggledb1c' ) == true ) {
         return true;
      }else{
         return false;
      }
   }
]);

Example 2: in this example the text field will only show at front page.

/**
 * Creating text field
 */
Yano::field( 'text', [
   'id'              => 'textdb1c',
   'label'           => 'Text',
   'section'         => 'active',
   'priority'        => 2,
   'active_callback' => 'show_in_front_page_only'
]);

/**
 * Creating a function show_in_front_page_only
 */
function show_in_front_page_only() {
   if( is_front_page() == true ) {
      return true;
   }
   return false;
}
