add_field via foreach

Resolved

(@teamcrisis)

Per your request Issue #261 I am posting this here.

I’m trying to add fields via a foreach:

add_action( 'cmb2_init', 'yourprefix_register_build_metabox' );

function yourprefix_register_build_metabox() {

	$post_id = isset($_GET['post']) ? $_GET['post'] : false;

	// Start with an underscore to hide fields from custom fields list
	$prefix = '_yourprefix_builder_';

	/**
	 * Metabox to be displayed on a single page ID
	 */
	$cmb_about_page = new_cmb2_box( array(
		'id'           => $prefix . 'metabox',
		'title'        => __( 'Build Metaboxes', 'cmb2' ),
		'object_types' => array( 'page', ), // Post type
		'context'      => 'normal',
		'priority'     => 'high',
		'show_names'   => TRUE, // Show field names on the left

	) );

	$cmb_about_page->add_field( array(
		'name' => __( 'Test Text', 'cmb2' ),
		'desc' => __( 'field description (optional)', 'cmb2' ),
		'id'   => $prefix . 'text',
		'type' => 'multicheck',
		'options' => array(
			'check1' => __( 'Check One', 'cmb2' ),
			'check2' => __( 'Check Two', 'cmb2' ),
			'check3' => __( 'Check Three', 'cmb2' ),
		),
	) );

	if ( $post_id ) {

		// Helper to find key label
		function search_for_meta_value( $value, $array ) {
			foreach ( $array as $key => $val ) {
				if ( $val['value'] === $value ) {
					return $val['label'];
				}
			}

			return NULL;
		}

		$builder_meta_boxes = get_post_meta( $post_id, '_yourprefix_builder_text', TRUE );

		if ( isset($builder_meta_boxes) && is_array($builder_meta_boxes)) {

			$text = get_post_meta( $post_id, '_yourprefix_builder_text', true );

			foreach($builder_meta_boxes as $value => $meta_box_name){ 

				$cmb_about_page->add_field( array(
				   'name'        => $meta_box_name . ' Field',
				   'desc'        => 'Set your value.',
				   'id'          => $prefix . $meta_box_name,
				   'type'        => 'checkbox',
				));
			}
		}
	}
}

The fields add without an issue, but the values do not save. Any idea why? I’m not seeing any info in the wiki about this. Did I simply miss it?

Yes, your values do not save because you’re wrapping field registration in a condition that checks for $_GET['post'] which does not exist during the save process. You should use the show_on_cb field (or metabox) parameter to conditionally display the fields.

What I’m attempting to do is add additional metaboxes based on the checkbox selection of a user. On $post_id = 1 they make make 5 selections, but on $post_id = 2 they may only make 1 selection. In this case, 5 metaboxes and 1 metabox respectively, may be added to the page on save.

Is this not possible to do with CMB?

Looks like doing a check for $_GET[‘post’] and $_POST[‘post_ID’] may do what I need. I’ll update if it doesn’t work for what I’m trying to accomplish.

teamcrisis, did this end up working itself out in the end?

Was looking for the same thing and yes , seems the checking of $_POST or $_GET does the work .
```
if(isset($_GET['post'])){
	$postID = $_GET['post'];
}

if(isset($_POST['post_ID'])){
	$postID = $_POST['post_ID'];
}
```
