Help with custom show_on

  • Hi there,
    I’m really loving CMB2 and it will most likely become a huge part of my WordPress workflow. However, I’m having trouble understanding how the custom show_on filters work.

    I have CMB2 inside a plugin like this:
    plugin_folder/
    – cmb2/
    – functionality.php

    So, let’s say I have some metaboxes in my functionality.php file, formatted like so:

    $meta_boxes['slide_fields'] = array(
		'id'			=> 'slide_fields',
		'title'			=> __( 'In Slider?'),
		'object_types'	=> array('slides'),
		'context'		=> 'side',
		'priority'		=> 'high',
		'show_names'	=> false,
		'fields'		=> array(
			array(
				'name' => __( 'Featured Slide', 'cmb2' ),
				'desc' => __( 'Show in slider? Only most recent 2 features will be displayed.', 'cmb2' ),
				'id'   => $prefix . 'slider_checkbox',
				'type' => 'checkbox',
				)
			),
	);

    …and then I want them to only show on a page with slug of ‘home’. So, I grab this filter. But how do use this filter?

    Would I write something like this?
    be_metabox_show_on_slug( true, $meta_boxes[slide_fields']);

    Should this be inside of my $meta_boxes array somehow?

    I’ve spent almost an hour trying to figure this out and apparently my brain just isn’t making the connection. Any help would be much appreciated.

    At the bottom of that example section is this line: add_filter( 'cmb_show_on', 'be_metabox_show_on_slug', 10, 2 );

    Basically tacking the function declared onto the cmb_show_on filter. However, with CMB2, the filters got renamed, so you’d want to use cmb2_show_on.

    See if that helps resolve the issue and make the time not completely wasted ??

    Thanks for the reply.
    I think the part I’m having trouble with is how to assign this hook to a specific set of boxes. If I only want to apply this filter to the fields inside of $meta_boxes[‘slide_fields’], do i need to add some more conditional logic to the filter somewhere?

    You’d want to inspect what’s coming in with the 2 parameters: $display, $meta_box

    Not sure if this is 1 metabox per pass through, or what, but if it is just one at a time, you’d need to check which metabox is currently being filtered and conditionally alter based on that.

    Oops. I’ll mark it as resolved.
