Populate the select field with another custom post type

There’s a couple different libraries for adding custom UIs for doing just that:

https://github.com/WebDevStudios/cmb2-attached-posts

There’s also a tutorial for doing what you’re asking in the project’s wiki:

Hi Justin,

excellent – thank you for the links ??

hi,

Almost there ??

My problem is I’m trying to make the checkbox value the same as the label and failing ??

The checkbox value is numeric while the label is the title of the custom post type (as intended). I’d like the value and the label to be the sane ie. Both to be the title of the custom post type.

Image below to show what I’m trying to do ??

Code below:

function cmb2_get_post_options( $query_args ) {

     $args = wp_parse_args( $query_args, array(
         'post_type'   => 'activity',
         'numberposts' => -1,
     ) );

     $posts = get_posts( $args );

     $post_options = array();
     if ( $posts ) {
         foreach ( $posts as $post ) {
           $post_options[ $post->ID ] = $post->post_title;
         }
     }

     return $post_options;
 }

$cmb2->add_field( array(
                    'name'    => __( 'Activities in this package', 'cmb2' ),
                    'desc'    => __( 'select the relevant activities', 'cmb2' ),
                    'id'      => $prefix . 'post_multicheckbox',
                    'type'    => 'multicheck',
                    'options' => cmb2_get_post_options( array( 'post_type' => 'activity', 'numberposts' => -1 , 'orderby' => 'name', 'order' => 'ASC' ) )
                         )
                    );

}

Normally the checkbox option is like the code below, but when I try to repeat this format everything breaks.

'options' => array(
        'check1' => 'Check One',
        'check2' => 'Check Two',
        'check3' => 'Check Three',
    )

Here’s hoping – thanks ??

Apologies – blind to the code.

Solved by editing the line to read

$post_options[ $post->post_title ] = $post->post_title;

What errors are you getting with this?

I’m curious if this line:

$post_options[ $post->ID ] = $post->post_title;

Needs to be more like:

$post_options[ 'check' . $post->ID ] = $post->post_title;

or if you’re not wanting the ID, I’d probably suggest the post slug for the options key.

Hi Michael,

See my self-correction just above your post. Thanks ??

Off by 8 minutes. Good to see you found a solution regardless ??

Hi,

I Found your feedback helpful for me.

I was not getting data when i was using like following :

$cmb_edu ->add_field( array(

'name'     => __( 'Related Languages', 'cmb2' ),
'desc'             => 'Select an option',
'id'       => $prefix . 'select_languages',
'type'	=> 'multicheck',
'options_cb' => cmb2_get_post_options(),

) );

But It’s working fine when i’ve done like following :

$cmb_edu ->add_field( array(

'name'     => __( 'Related Languages', 'cmb2' ),
'desc'             => 'Select an option',
'id'       => $prefix . 'select_languages',
'type'	=> 'multicheck',
'options' => cmb2_get_post_options( array( 'post_type' => 'language' ) )
) );

So we can say that the “options_cb” is not working as they have said in example of cmb2.

Anyone help me to understand what can be the problem ?

Thanks for everything.

If you were copying the example code above exactly, then your first version is going to default to looking for a post type of “activity” which you may not have registered with your site. Once you passed in the “language” post type, you were using one your site DID have, thus had something to return.

Unless I’m mistaken, it’s a case of a default value not being available to you.
