I have a group defined with two fields in it: a text field and a URL field. The idea is the text field is the Link Text and the URL is ... the URL. How can I display these as links on my template?

Partially answered my own question by reading the MB Group documentation. Created a custom shortcode like this. However, this is not returning the appropriate values.

Do you see any issues?


add_shortcode( 'references', function() {
    $group = rwmb_meta( 'references' );
    if ( empty( $group ) ) {
        return '';
    }

    $output = '';

    // Reference URL
    $rlabel = $group['reference_label'] ?? '';
    $rurl = $group['reference_url'] ?? '';
    $output .= '<a href="' . $rurl . '">' . $rlabel . '</a>';
    return $output;
} );

Hi David,

Can you please share the code that creates the group and subfields? If you are using the builder, please refer to this documentation https://docs.metabox.io/extensions/meta-box-builder/#getting-php-code

<?php
add_filter( 'rwmb_meta_boxes', 'your_prefix_function_name' );

function your_prefix_function_name( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'      => __( 'References', 'your-text-domain' ),
        'id'         => 'references',
        'post_types' => ['control'],
        'fields'     => [
            [
                'id'     => $prefix . 'references',
                'type'   => 'group',
                'clone'  => true,
                'fields' => [
                    [
                        'name' => __( 'Reference Label', 'your-text-domain' ),
                        'id'   => $prefix . 'myreference_label',
                        'type' => 'text',
                    ],
                    [
                        'name' => __( 'Reference URL', 'your-text-domain' ),
                        'id'   => $prefix . 'myreference_url',
                        'type' => 'url',
                    ],
                ],
            ],
        ],
    ];

    return $meta_boxes;
}

Here's my latest shortcode function:

add_shortcode( 'references', function() {
    $group = rwmb_meta( 'references' );
	//return $group;
    if ( empty( $group ) ) {
        return '';
    }

    $output = '';

    // Reference URL
    $rlabel = $group['myreference_label'] ?? '';
    $rurl = $group['myreference_url'] ?? '';
    $output .= '<a href="' . $rurl . '">' . $rlabel . '</a>';
    return $output;
});

Hi,

It's a cloneable group, then you need to create a loop to iterate through an array of groups.

add_shortcode( 'references', function() {
    $groups = rwmb_meta( 'references' );
    //return $groups;
    if ( empty( $groups ) ) {
        return '';
    }

    $output = '';
    foreach ( $groups as $group ) {
        // Reference URL
        $rlabel = $group['myreference_label'] ?? '';
        $rurl = $group['myreference_url'] ?? '';
        $output .= '<a href="' . $rurl . '">' . $rlabel . '</a>';
    }
    
    return $output;
} );
