GF and ACF

Hi,
I created a complete Custom Post Admin with http://www.advancedcustomfields.com/
I just give some fields for a simple example :
My collecttion CPT is composed by :
## Title (WP default CPT title)
## ACF Description name "description_collections"
## ACF Taxonomy Fieds name "genre_collections"
## ACF Gallery Fields (add-on $) name "image_collections"

Now GF, i used :
## Gravity Forms + Custom Post Types add-on to put form in the CPT Collection (That's work)
## Article Post Title to put the Title of my CPT Collection (i use the title wp field default, so that's work)
## Custom Field Post (textarea) to submit my description (that's work too)
Problems come now...
------
## For the taxonomy, i used Standard field CheckBoxes with advanced "Populate with a Taxonomy" with my custom taxonomy...
- work for the WP taxonomy, i can see in admin edit collection the tax
- not work for my custom ACF field because i can't set the value of the custom field with the GF checkboxen tool
## For the gallery, i used the Image Field of GF Article post...
- work for the WP image, i can see all images link with this post submitted
- not work for my custom ACF field...

I think i can fix this problem, but not alone, because i'm really new be on php and GF custom function.

I use the var_dump function to see what was the waiting values of the ACF fields, so :
## ACF taxonomy field seems waiting an array :
get_post_meta($post->ID, 'genre_collections', true)
===> array(2) { [0]=> string(1) "3" [1]=> string(2) "15" }
===> array(2) { [0]=> string(1) "TAX_ID_1" [1]=> string(2) "TAX_ID_2" }

## ACF Gallerie field seems waiting an array too :
get_post_meta($post->ID, 'image_collections', true)
===> array(6) { [0]=> string(2) "60" [1]=> string(2) "57" [2]=> string(2) "58" [3]=> string(2) "59" [4]=> string(2) "61" [5]=> string(2) "62" }
===> array(6) { [0]=> string(2) "ATTACHEMENT_POST_ID_1" [1]=> string(2) "ATTACHEMENT_POST_ID_2" [2]=> etc......

So if i understood your documentation i need to use the http://www.gravityhelp.com/documentation/page/Gform_pre_submission to transform the GF_Fields in array and store in database ?

Am i on the right way ? And can you help me to do the function, because i think there are some loop and count... It's hard for me to play with that...
My head work well but not my php =)

Thank you

@illinoisharley, thanks for reply, i keep going before spend money.
But can you tell me how can i retry the ATTACHEMENT_ID and where i need to do the update meta field ?
## Gform_pre_submission
## Gform_after_submission (i think here ?)

Thank you

Laurent

Oh Yeah !

That's work, today is a little step for you, but a big one for me =)

So for other : Function change Gravity Form image post upload to an Advanced Custom Fields add-on Gallery (maybe can help...)

add_action("gform_after_submission_$formID", "acf_gallery_gformAfterSubmission", 10, 2);
function acf_gallery_gformAfterSubmission ($entry, $form)
{
   $post_id = $entry["post_id"];
		$attachments = get_posts( array(
			'post_type' => 'attachment',
			'posts_per_page' => -1,
			'post_parent' => $post_id
		) );

		if ( $attachments ) {
			foreach ( $attachments as $attachment ) {
				$image_collections[] = strval($attachment->ID) ;
			}
		}

	$image_collections = serialize($image_collections);
	update_post_meta($post_id,'image_collections',$image_collections);

}

Maybe this function can be optimized...

See you

@popsantiago: well done!
