I want to add a field in my custom meta box, same as below, but not for tags. How can I repeatedly take more inputs in the same field?

enter image description here

Here is my code added to functions.php:

function dikka_cmb_meoxes( array $meta_boxes ) {
    $prefix = 'dikka_';
    $meta_boxes['details_meox'] = array(
        'id'         => 'details_meox',
        'title'      => __( 'Porject Details', 'dikka' ),
        'pages'      => array( 'portfolio', ), // Post type
        'context'    => 'normal',
        'priority'   => 'high',
        'show_names' => true, // Show field names on the left
        'fields'     => array(
            array(
                'name'     => __( 'Client', 'dikka' ),
                'desc'     => __( 'Add client name', 'dikka' ),
                'id'       => $prefix . 'add_client',
                'type'     => 'text',
            ),
            array(
                'name'     => __( 'Skills', 'dikka' ),
                'desc'     => __( 'Add skills', 'dikka' ),
                'id'       => $prefix . 'skills',
                'type'     => 'text',
            ),
            array(
                'name'     => __( 'Release Date', 'dikka' ),
                'desc'     => __( 'Add release date of project', 'dikka' ),
                'id'       => $prefix . 'add_releasedate',
                'type'     => 'text_date',
            ),
        )
    );
    return $meta_boxes;
}
  • You want a custom meta-field which functions the same like the default WP "Tags" metabox? An input field to select already existing values and/or to add new value on the fly? You could try using "Select2". Especially with the "tagging" feature here which is exactly the functionality you want. So with "Select2" you could create one single new select field with the tagging feature. Than you just need to save the data of the field as an array. No need for a real repeater field, imo. – LWS-Mo Sep 1 '17 at 14:46

If looks like you are using CMB (Custom-Metaboxes-and-Fields-for-WordPress) to create your create metaboxes. CMB is already supplying a option to group and repeat meta box that you can use. You can check this link

As far as your code it is concern if suppose it should go like this:

function dikka_cmb_meoxes( array $meta_boxes ) {
    $prefix = 'dikka_';
        $meta_boxes['details_meox'] = array(
        'id'          => $prefix . 'details_meox',
        'type'        => 'group',
        'pages'      => array( 'portfolio', ), // Post type
        'description' => __( 'Porject Details', 'dikka' ),
        'options'     => array(
            'group_title'   => __( 'Entry {#}', 'dikka' ), // since version 1.1.4, {#} gets replaced by row number
            'add_button'    => __( 'Add Another Entry', 'dikka' ),
            'remove_button' => __( 'Remove Entry', 'dikka' ),
            'sortable'      => true, // beta
        ),
        // Fields array works the same, except id's only need to be unique for this group. Prefix is not needed.
        'fields'     => array(
            array(
                'name'     => __( 'Client', 'dikka' ),
                'desc'     => __( 'Add client name', 'dikka' ),
                'id'       => $prefix . 'add_client',
                'type'     => 'text',
            ),
            array(
                'name'     => __( 'Skills', 'dikka' ),
                'desc'     => __( 'Add skills', 'dikka' ),
                'id'       => $prefix . 'skills',
                'type'     => 'text',
            ),
            array(
                'name'     => __( 'Release Date', 'dikka' ),
                'desc'     => __( 'Add release date of project', 'dikka' ),
                'id'       => $prefix . 'add_releasedate',
                'type'     => 'text_date',
            ),
        ),
    ),

    return $meta_boxes;
}

Hope this helps!
