Creating metaboxes in loop

  • Hello, I want to create metaboxes in foreach loop. The requirement is, I have an array of custom post types and I want to run a loop to add metaboxes for the post types that are as a key in an array.
    So far I have developed much of the requirement but now I am stuck in the part where callback function inside add_meta_box() is to be called. I have used call_user_func_array to call the callback function and pass the $key as an argument but it is returning error and its not working. Below is my code:

    
	 function rttk_create_boxes(){
		$myarray = $this->rttk_get_posttype_array();
		foreach ($myarray as $key => $value) {
			// echo "key--".$key;
			// $arr[] = '';
			// $arr[] = $key;
			$key = (array)$key;
			add_meta_box(
				'rttk_'.end($key).'_id',
				__( 'Details', 'rara-theme-toolkit-pro' ),
				//array($this,'rttk_testimonials_metabox_callback',$key),
				call_user_func_array(array( $this, 'rttk_testimonials_metabox_callback'),$key ),
				$key,
				'side',
				'high'
			);
		}
	}

	// testimonials template form
	public function rttk_testimonials_metabox_callback($key){
		// $myarray = $this->rttk_get_posttype_array();
		// foreach ($myarray as $key => $value) {
			include RTTKPRO_BASE_PATH.'/includes/meta-parts/rttk-'.$key.'-template.php';
		// }
	}

    Any help would be highly appreciated.
    Thanks!

  • the function declaration says,

    add_meta_box( string $id, string $title, callable $callback, string|array|WP_Screen $screen = null, string $context = 'advanced', string $priority = 'default', array $callback_args = null )

    Notice the last parameter $callback_args. You can pass an array as callback args.

    function rttk_create_boxes(){
	$myarray = $this->rttk_get_posttype_array();
	foreach ($myarray as $key => $value) {
		add_meta_box(
			'rttk_'.$key.'_id', //assuming each key is different
			__( 'Details', 'rara-theme-toolkit-pro' ),
			array($this,'rttk_testimonials_metabox_callback'),
			$screen, // WP_Screen
			'side',
			'high',
			array('key' => $key), // This is what you need
		);
	}
}

public function rttk_testimonials_metabox_callback( $post, $callback_args ){
	$key = $callback_args['args']['key'];
	include RTTKPRO_BASE_PATH.'/includes/meta-parts/rttk-'.$key.'-template.php';
}

    See if this is working.
