Hi GF

I am looking for solution to allow a gravity form to dynamically pull in the featured image of a post the same way it can pull in the post title.

Basically this is a form on a products website. On the product details page is a modal with an enquiry form in it (a gravity form). I need it that when the user opens the modal with the form, two fields need to populate automatically - the post title and the featured image. We have the post title working, but cannot get the image to display.

We tried something like this:
add_filter('gform_field_value_prodimage', 'populate_post_prodimage'); function populate_post_prodimage($value){ global $post; $prodimg = set_post_thumbnail($entry['post_id']); return $prodimg; }
Copy
But it doesn't appear to be working.

Any suggestion?

Why are you using 'set_post_thumbail' here, if you are trying to retrieve what is saved as the featured image? How about get_the_post_thumbnail http://codex.wordpress.org/Function_Reference/get_the_post_thumbnail

In case anyone else trying to find a solution, i finally managed to hack this solution:

add_filter('gform_field_choices', 'update_choices', 10, 2);
function update_choices($choice_html, $field){

if($field['formId'] != 3)
return $choice_html;

if($field['id'] == 21) {
// in this example, "First Choice" is one of the option labels, we replace that with the image
// the reason we include the "><" when searching for the "First Choice" text is because unless
// the 'enable values' option is selected for this field, it would replace both the value and
// the label, we just want to update the label

global $post;
$feat1 = '<img src="';
$feat2 = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
$feat3 = '" width="250" height="220" />';
$featimage = $feat1 . $feat2 . $feat3;
return $featimage;
}
