Connect a File Upload field to a Gallery Custom Field

Hi @tomaspe96

I hope you are doing well.

It should be possible with some custom coding as you are trying to do, I am not familiar to metabox plugin since I see you are using it but we forwarded the code and form to our developers to take a closer look.

We will keep you posted.

Thanks for the reply @wpmudevsupport12 ! If the team is or was able to do such a thing with ACF gallery field before, I could try to make it work with some tweaks in metabox, i don’t want to bother the team too much!

HI @tomaspe96

Thanks for response!

Our team will look into it since Patrick already ask them to do so ??

I can’t promise at this moment if/what will they be able to come up with but surely they’ll check it and once we got feedback we’ll update you here agian.

Have a great day!

Hi @tomaspe96

I just got code from our developers, it should help.

<?php 

add_action( 'forminator_post_data_field_post_saved', 'wpmudev_change_upload_field_image', 10, 4 );
function wpmudev_change_upload_field_image( $post_id, $field, $data, $Forminator_Postdata ){
	$post_meta   = isset( $data['post-custom'] ) ? $data['post-custom'] : '';
	$img_id = array();
	if ( !empty( $post_meta ) ) {
		foreach ( $post_meta as $pmeta ) {
			if( $pmeta['key'] == 'blc_slider' ){
				delete_post_meta( $post_id, $pmeta['key'] );
				if( strpos( $pmeta['value'], ',' ) !== false ){
					$images = explode(', ', $pmeta['value']);
					foreach( $images as $img_key => $img_url ){
						add_post_meta( $post_id, $pmeta['key'], attachment_url_to_postid( $img_url ) );
					}
				}else{
					add_post_meta( $post_id, $pmeta['key'], attachment_url_to_postid( $pmeta['value'] ) );
				}
			}
		}
	}
}

To use it on site as MU plugin:

– create an empty file with a .php extension
– put the code into it
– save the file and upload it to the “/wp-content/mu-plugins/” folder of your site’s WordPress installation.

Note also:

– this code assumes that you didn’t change “mapping” of your upload field to custom field; if it’s changed you may need to adjust form field and custom field names in the code

– to allow multiple fields, you will need to change setting of upload field in the form from “single” to “multiple”

I’d also strongly recommend testing this first on some dev/staging site before adding to live one.
