Meta Box

You can set query_args parameter for from and to to limit the query. If you know the IDs of selected items, you can do this:

MB_Relationships_API::register( [
    'id'   => 'posts_to_pages',
    'from' => [
        'post_types' => 'post',
        'query_args' => [ 'post__in' => [1,2,3], 'posts_per_page' => 10 ],
    ],
    'to'   => 'page',
] );

Hi Will,

For WP_Query, the plugin doesn't integrate with it. You need to perform an extra query to get the posts you want, then use the returned ID to create your own WP_Query.

global $wpdb;
$ids = $wpdb->get_col( "SELECT ID FROM your_table WHERE field1='value1' OR field2='value2'" );

$query = new WP_Query( [
    'post_type' => 'post',
    'post__in'  => $id,
] );

Hi ComSi,

Have you ever drag and drop the meta boxes? If you have, then WP will save the position/location of them and makes the "context" param not working. The data is saved in the user meta meta-box-order_{screen id}:

Deleting this user meta from the database will make the context work again.

Please try that. It's the only reason I think affects the wrong location.

Probably, you're on an old post or your meta box has already been saved. See this for more details:

Hi Camilo,

Actually, you are setting the field in opposite. The correct pattern should be:

'value1' => 'Label 1',
'value2' => 'Label 2'

(It's the 'value' => 'Label', not 'key' => 'value').

And the helper function returns the values, not labels.

You can get the labels, you can do this:

$field = rwmb_get_field_settings( 'field_id' );
$options = $field['options'];

// Get all labels.
$values = rwmb_meta( 'field_id' );
$labels = array_map( function( $value ) use ( $options ) {
    return $options[$value];
}, $values );

// Output labels.
foreach ( $labels as $label ) {
    echo $label;
}

Hi Dave,

All media fields store attachment IDs by default. If you want to store file URL (not path), then you can try file field with upload_dir settings. See this for details:

https://docs.metabox.io/fields/file/#upload-to-custom-folder

I got it.

There is a settings clone_default for each field if you want to clone default values. You can set the default value for the whole group (which is an array of default values for sub-fields). Then when cloning, these values will be selected automatically.

For user-selected options, they will be cleared when cloning. It's the design at first, since it makes the new clone clean and easy to start entering new values.
