How to manually create WooCommerce Product Image Gallery using WPUF

If you want to insert WooCommerce product image gallery via WP User Frontend PRO, you’ll see only 1 image shows in the gallery. WooCommerce uses _product_image_gallery custom field to store the image gallery. It stores those images/attachments IDs separated by comma. Ex: 32,34,3874 in that single custom field. WP User Frontend PRO stores also the images/attachments IDs, but in the same meta key, but separately. For example:

'_image_gallery' => 383
'_image_gallery' => 345

To solve this issue, we’ll be adding a image upload field in the form editor with a different name (that woocommerce doesn’t uses).

Here we are using _product_image meta key to store the image for product gallery. The trick is, we’ll save the image IDs to the WooCommerce’s _product_image_gallery meta key when we hit submit/update button in our form.

/**
* Update the custom field when the form submits
*
* @param type $post_id
*/
function wpuf_woo_product_gallery( $post_id ) {
if ( isset( $_POST['wpuf_files']['_product_image'] ) ) {

$images = get_post_meta($post_id, '_product_image' );
update_post_meta( $post_id, '_product_image_gallery', implode(',', $images) );
}
}

add_action( 'wpuf_add_post_after_insert', 'wpuf_woo_product_gallery' );
add_action( 'wpuf_edit_post_after_update', 'wpuf_woo_product_gallery' );

Paste the code in your themes functions.php and your product gallery will be showing perfectly.
