    Hi,

    I have a strange issue that has been driving me crazy. I have a published field group that will not display on the front end via shortcode.

    I have several other shortcodes that are almost identical (different custom field groups) and displaying content on the front end in Beaver Themer, but no matter what I do this one only ever returns an empty() result for the custom fields.

    Can anyone give me any suggestions as to why I can retrieve and display these custom fields on the front end?

    Here’s the code from the custom fields settings:

    add_filter( 'rwmb_meta_boxes', 'your_prefix_register_meta_boxes' );
    
    function your_prefix_register_meta_boxes( $meta_boxes ) {
        $prefix = '';
    
        $meta_boxes[] = array (
            'title' => esc_html__( 'Composition', 'text-domain' ),
            'id' => 'composition',
            'post_types' => array(
                0 => 'sock',
            ),
            'context' => 'normal',
            'priority' => 'low',
            'fields' => array(
                array (
                    'id' => $prefix . 'percent_combed_cotton',
                    'type' => 'number',
                    'name' => esc_html__( 'Combed Cotton', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_cotton',
                    'type' => 'number',
                    'name' => esc_html__( 'Cotton', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_nylon',
                    'type' => 'number',
                    'name' => esc_html__( 'Nylon', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_elastane',
                    'type' => 'number',
                    'name' => esc_html__( 'Elastane', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_spandex',
                    'type' => 'number',
                    'name' => esc_html__( 'Spandex', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_wool',
                    'type' => 'number',
                    'name' => esc_html__( 'Wool', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_merino',
                    'type' => 'number',
                    'name' => esc_html__( 'Merino Wool', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_acrylic',
                    'type' => 'number',
                    'name' => esc_html__( 'Acrylic', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
                array (
                    'id' => $prefix . 'percent_elastic',
                    'type' => 'number',
                    'name' => esc_html__( 'Elastic', 'text-domain' ),
                    'max' => 100,
                    'step' => 1,
                    'columns' => 3,
                ),
            ),
        );
    
        return $meta_boxes;
    }

    Here is the shortcode:

    /**
     * @return false|string
     *
     * Shortcode to display compositon
     */
    function sock_composition_func()
    {
        $sockcomp = rwmb_meta('composition');
    
        ob_start();
    
        if ( empty( $sockcomp ) ) {
            return 'no sock composition found';
        }
    
        print_r($sockcomp);  // my output code will go here but it never displays because $sockcomp always returns empty()
    
        return ob_get_clean();
    }
    add_shortcode('sock_composition', 'sock_composition_func');

    Hi,

    There is a confusion with your shortcode, composition is the meta box ID and the function rwmb_meta() supports to display the field value with the field ID. Please try to create the field group and get the value with the function rwmb_meta() again.

    For more information, please follow the documentation
    https://docs.metabox.io/displaying-fields/
    https://docs.metabox.io/extensions/meta-box-group/

    Hi Long,

    Thanks for the fast reply.

    Ah… I see where I was confused now.

    I assumed when I created a new Custom Fields “Field Group” using WP-Admin -> MetaBox -> Custom Fields that this was a MetaBox group that the sample code would work with. Newbie mistake.

    I now see the Group option in the WP-Admin -> MetaBox -> Custom Fields UI, have moved the indivdiual fields in and I’m now getting each $key => $value back using a foreach loop.

    Thank you!

    So the final question I have is… how can I retrieve the field Name and Description as well as the field value?

    Using the fields above (now in a group) I want to output a list of sock composition elements. For example; “Cotton 72%, Elastic 10%, Combed Cotton 18%”.

    It would be great if I could retrieve the field Name, Description, as well as the id and value – are you able to tell me how to do this?

    I’m sure it’s simple, but I’m still noobing through the documentation and haven’t spotted it.

    Absolutely loving MetaBox though – this is amazing.

    Solved it!

    Found rwmb_get_field_settings(). 😀

    This is my shortcode now which is working great.

    Thanks again!

    /**
     * @return false|string
     *
     * Shortcode to display compositon
     */
    function sock_composition_func()
    {
        ob_start();
    
        // grab the details of subfields in the composition_group MetaBox group.
        $sockcomp = rwmb_meta('composition_group');
    
          if ( empty( $sockcomp ) ) {
            return 'No sock composition values have been entered.';
        }
    
        // get the subfields of the composition_group MetaBox group
        $subfields = rwmb_get_field_settings('composition_group')[fields];
    
        $composition = array();
    
        // Loop through and add "Name: Value%" to an array.
        foreach ($subfields as $subfield ) {
            $composition[] = $subfield['name']. " ". rwmb_meta($subfield['id']) . "%";
        }
    
        // return as comma separated output, excluding last comma
        echo '<span class="composition-list">' . implode(",&nbsp;&nbsp;", $composition) . '</span>';
    
        return ob_get_clean();
    }
    add_shortcode('sock_composition', 'sock_composition_func');
