Please how could i get the first image url from an array.

foreach ( $disli as $value ) {
    $image = RWMB_Image_Field::file_info( $value, ['size' => 'large'] );
    echo '<a href="' . $image['url'] . '" data-lightbox="'.$dislider['gallname'].'"></a>';
}

echo '<a href="'.$image['url'][0]. // first item ?? '"
 data-lightbox="'.$dislider['gallname'].'">

<span class="material-icons imag" style="display: block;color:'.$dislider['textcolorr'].'">image</span>
</a>';

I need to open lightbox with icon but icon needs an url to open it.

Hi,

Follow your previous topic: https://support.metabox.io/topic/get-advanced-images-from-array/

/**
 * return an array of image IDs 
[0] => 234
[1] => 456
[2] => 831
[3] => 1112
 */
$disli = $dislider['gallimage'];

To get the first image from the field image_advanced value, please follow this code:

$image = RWMB_Image_Field::file_info( $disli[0], ['size' => 'large'] );
echo '<a href="' . $image['url'] . '" data-lightbox="'.$dislider['gallname'].'"></a>';
