Usage

acf_photo_gallery is a helper function that takes in ACF_FIELD_NAME and POST_ID will query the database and compile the images for you. The output of this function will be an array.

acf_photo_gallery(ACF_FIELD_NAME, POST_ID);

Example

The following example is using Twitter Bootstrap framework to layout. You can use any framework of your choice.

<?php
    //Get the images ids from the post_metadata
    $images = acf_photo_gallery('vacation_photos', $post->ID);
    //Check if return array has anything in it
    if( count($images) ):
        //Cool, we got some data so now let's loop over it
        foreach($images as $image):
            $id = $image['id']; // The attachment id of the media
            $title = $image['title']; //The title
            $caption= $image['caption']; //The caption
            $full_image_url= $image['full_image_url']; //Full size image url
            $full_image_url = acf_photo_gallery_resize_image($full_image_url, 262, 160); //Resized size to 262px width by 160px height image url
            $thumbnail_image_url= $image['thumbnail_image_url']; //Get the thumbnail size image url 150px by 150px
            $url= $image['url']; //Goto any link when clicked
            $target= $image['target']; //Open normal or new tab
            $alt = get_field('photo_gallery_alt', $id); //Get the alt which is a extra field (See below how to add extra fields)
            $class = get_field('photo_gallery_class', $id); //Get the class which is a extra field (See below how to add extra fields)
?>
<div class="col-xs-6 col-md-3">
    <div class="thumbnail">
        <?php if( !empty($url) ){ ?><a href="<?php echo $url; ?>" <?php echo ($target == 'true' )? 'target="_blank"': ''; ?>><?php } ?>
            <img src="<?php echo $full_image_url; ?>" alt="<?php echo $title; ?>" title="<?php echo $title; ?>">
        <?php if( !empty($url) ){ ?></a><?php } ?>
    </div>
</div>
<?php endforeach; endif; ?>

Add Extra Fields

    $args['alt'] = array(
        'type' => 'text', 
        'label' => 'Altnative Text', 
        'name' => 'alt', 
        'value' => get_field($field . '_alt', $attachment_id)
    );
    $args['status'] = array(
        'type' => 'select', 
        'label' => 'Status', 
        'name' => 'status', 
        'value' => array(
            array(
                '1' => 'Active',
                 '2' => 'Inactive'
            ), 
            get_field($field . '_status', $attachment_id)
        )
