I am working through getting to know the plugin.

It is possible to put single image into group? I tried the Group tutorial sample and got no result

Here is the sample I modified.

<?php
$product_colour = rwmb_meta( 'product-colour' ); // ID of the group
if ( ! empty( $product_colour ) ) {
    echo '<h3>', $product_colour['title'], '</h3>';
    echo '<h3>', $product_colour['image'], '</h3>';
} ?>

Also I am getting Undefined index: title error and not sure what that mean?

Anyone know how to group image and text?

Hi William,

It's necessary to check if a group has sub-values for title and image. Please try this code:

<?php
$product_colour = rwmb_meta( 'product-colour' ); // ID of the group
if ( ! empty( $product_colour ) ) {
    if ( ! empty( $product_colour['title'] ) ) {
        echo '<h3>', $product_colour['title'], '</h3>';
    }
    if ( ! empty( $product_colour['image'] ) ) {
        $image = RWMB_Image_Field::file_info( $product_colour['image'], ['size' => 'thumbnail'] );
        echo '<img src="', $image['url'], '">';
    }
}
?>
