How To Add Meta Box Dynamically

Hi,

That can be done with our Meta Box Conditional Logic extension.

Hi Anh,

I have already installed the Meta Box Conditional Logic extension and read it’s documentation. But I wasn’t really able to achieve what I wanted. Can you please help?

Hi @theshivanjali ,

I think I misunderstood your question. I thought you already created meta boxes and use the Conditional Logic extension to toggle them.

Looks like you want to create meta boxes dynamically. I think that’s still doable like this:

– You create a quantity field for entering the number of meta boxes
– In your rwmb_meta_boxes filter callback, you need to get that number and register meta boxes based on that number

Here is a sample code:

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
	// Quantity field.
	$meta_boxes[] = [
		'title' => 'Quantity',
		'fields' => [
			[
				'id' => 'quantity',
				'type' => 'number',
				'name' => 'Quantity',
			]
		],
	];

	// Dynamic create meta boxes.
	if ( isset( $_GET['post'] ) ) { // If edit post only.
		$quantity = get_post_meta( $_GET['post'], 'quantity', true );
		for ( $i = 0; $i < $quantity; $i++ ) {
			$meta_boxes[] = [
				'title' => "IMEI #$i",
				'fields' => [
					[
						'id' => "imei_$i",
						'name' => 'IMEI',
					]
				],
			];
		}
	}

	return $meta_boxes;
} );

Just a note that because the meta boxes are dynamically created, you need to save post to see them.
