get_field( ) Gallery Performance

  • When using get_field(‘image_gallery’) with the gallery add-on causes a huge performance slow down. Especially when displaying many galleries on the same page from different posts. The only work around was to use a custom sql statement to target specific gallery. We believe the issues is the serialization of the data. It would be convenient to use get_field as documented.

    $sql = "select meta_value from wp_postmeta where post_id='".$post_id."' and meta_key='image_gallery' ";
    	$result = mysql_query($sql);
    	if (!mysql_num_rows($result)) {return;}
    	$row = mysql_fetch_array($result);
    	$val = $row[0];
    	$imageArray = unserialize($val);
    

    And call the image(s) like this:

    foreach($imageArray as $img):
    	$imageURL = wp_get_attachment_image_src($img,'IMAGE SIZE');
            echo '<image src="'.$imageURL.'" />';
    endforeach;
  • Hi @jason Prescher

    It is possible to load the DB value WITHOUT any formatting like so:

    
    $ids = get_field('image_gallery');
    

    You can then loop over these ID’s and do as you wish.

    Thanks
