In gravity forms there are two upload fields:
post image: this one has no size and dimension settings and is limited
fileupload: great but cannot upload to the media library

you can add fileupload as custom field but it just uses the src tot he gravity form upload and it wont add it to library.
This fixes that!

Just add a new gfield of custom field. set it to upload. You can even set it to multiple!
It will save an array of the images into the custom field and upload them to the media library.
Works great with Pods.

Now you can add the css class thumb onto the file upload you want to make into a thumbnail -featured image

I'm using this snippet now, and for some reason, it's creating a draft post at the same time as it's uploading the image to the media library. Is there any way to avoid this from happening?

@intothevoid0 As far as i know, Custom Fields are generally used for attaching to form field data to the post meta, which is why you're getting a draft post being created... to be honest, don't think there is a way around that unfortunately

Quick question... how do we assign the new image URL (from the media gallery) to the custom field. Currently, the upload works great, but the custom field is still pointing to the gravity forms upload directory and not the Media Gallery upload directory. See screenshot here: http://b3.ms/P5Z9ZD6gKnlb

Would like to update it to the URL of the uploaded photo after this function has placed it into the WP Media Gallery: http://idahoforests.local/wp-content/uploads/forest-photo-driggs5.jpg

Hi, I'm getting this error

Catchable fatal error: Object of class WP_Error could not be converted to string in C:\wamp64\www\Intranet\wp-content\themes\woffice\functions.php on line 152

Line 152 is the $query assignment

$query = "SELECT ID FROM '{$wpdb->posts}' WHERE guid='$image_src'";

any idea on why I'm getting this error?
