Add custom field not editable by Members

@ ottomek

re: What would the snippet be to create this text field that only the WP admin could change but it would be read-only/displayed with each Members Profile Directory area.

The following snippet should do the trick.

// Register the metabox and field.
add_action( 'cn_metabox', 'cn_register_custom_metabox_and_date_field' );

function cn_register_custom_metabox_and_date_field() {

    $atts = array(
        'title'    => 'Expiration Date',         // Change this to a name which applies to your project.
        'id'       => 'expiration_date_metabox', // Change this so it is unique to you project.
        'context'  => 'normal',
        'priority' => 'core',
        'fields'   => array(
            array(
                'name'       => 'Date',            // Change this field name to something which applies to you project.
                'show_label' => TRUE,              // Whether or not to display the 'name'. Changing it to false will suppress the name.
                'id'         => 'expiration_date', // Change this so it is unique to you project. Each field id MUST be unique.
                'type'       => 'datepicker',      // This is the field type being added.
            ),
        ),
    );

    if ( is_admin() && current_user_can( 'manage_options' ) ) cnMetaboxAPI::add( $atts );
}

Hope that helps!

Hmmm… there is actually no way to do this presently. If you change the code snippet to this:

// Register the metabox and field.
add_action( 'cn_metabox', 'cn_register_custom_metabox_and_date_field' );

function cn_register_custom_metabox_and_date_field() {

    $atts = array(
        'title'    => 'Expiration Date',         // Change this to a name which applies to your project.
        'id'       => 'expiration_date_metabox', // Change this so it is unique to you project.
        'context'  => 'normal',
        'priority' => 'core',
        'fields'   => array(
            array(
                'name'       => 'Date',            // Change this field name to something which applies to you project.
                'show_label' => TRUE,              // Whether or not to display the 'name'. Changing it to false will suppress the name.
                'id'         => 'expiration_date', // Change this so it is unique to you project. Each field id MUST be unique.
                'type'       => 'datepicker',      // This is the field type being added.
                'readonly'   => is_admin() && ! current_user_can( 'manage_options' ) ? TRUE : FALSE
            ),
        ),
    );

    cnMetaboxAPI::add( $atts );
}

And make these changes to Connections ../includes/class.metabox-api.php file, it will work the way you want. I’ve already made the change and it’ll included in the next update.

Hope that helps!

Great to hear! I’ll add the readonly option to the other supported fields in the next update.
