Hi. I hope, it's my last support question. Easy for you difficult for me.
How could i get images from array to lightbox

I created an image advanced array on wordpress
```
array(
    
    'name'             => 'Add Gallery',
    'id'               => 'gallimage',
    'type'             => 'image_advanced',
    'force_delete'     => false,
    'max_file_uploads' => 10,
    'max_status'       => 'false',
    'image_size'       => 'thumbnail',
),
```
on frontend i need to make foreach
```
$disli = $dislider['gallimage'];//array?

foreach ( $disli as $value ) {
  echo '<a href="'.$value['full_url'].'" data-lightbox="bla"></a>';//give me error

  
}
```
Thank you. Sorry, I'm not a coder just a lifetime beginner

Hi Martin,

For specific field types such as media fields file, file_advanced, file_upload, image, image_advanced, image_upload, single_image, you might need to add some extra code to get the field details.
```
$group = rwmb_meta( 'group_id' );
$image_ids = $group['image_key'] ?? : [];
foreach ( $image_ids as $image_id ) {
    $image = RWMB_Image_Field::file_info( $image_id, ['size' => 'thumbnail'] );
    echo '<img src="' . $image['url'] . '">';
}
```
See more in the documentation https://docs.metabox.io/extensions/meta-box-group/#sub-field-values.

The code to show images in your case would be:
```
$disli = $dislider['gallimage'];//array?

foreach ( $disli as $value ) {
    $image = RWMB_Image_Field::file_info( $value, ['size' => 'thumbnail'] );
    echo '<img src="' . $image['url'] . '">';
}
```

Hi,

I'm not sure how the script (lightbox) implements its code. Please try to contact the script support to ask for help in this case.
