Hey guys,

I'm doing a bunch of custom stuff with my forms and need a little help figuring out one last step.

Here's a bit of background:
- I'm using my form to create a custom post
- When the custom post is saved/published, a row is inserted into a custom table
- I need my second form (an update form) to update this custom post
- I'm using gform_post_data_2 to target my update form

I'm trying to figure out how to update the featured image of the post. I can't find any functions that will do it for me.

Anyone have any tips?

Thanks,
Jacob

Did you ever figure this out? I'm looking for the same thing.

I have a form that let's people submit an image to a post which is already set. The form uses the gform_after_submission and update_post_meta to update the fileds on the form, but I'm not sure how to have it set the featured image. It uploads the image just fine... but having the "set as featured image" box checked on the upload box in the admin side doesn't effect the function because it's editing, not creating, a post.

Do you want to set the most recently uploaded image as the featured image then? You probably want to use set_post_thumbnail in the function you hooked to gform_after_submission.

Grab the last attachment to the post, and set that as the post thumbnail. Can you try that?

Okay... here's what I'm trying now... to no avail.

add_action( 'gform_after_submission_6', 'gf_edit_student', 10, 2 );
function gf_edit_student( $entry, $form ) {
global $post;
global $wpdb;
global $wp_query;
$postID = $wp_query->post->ID;

$post_thumbnail = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_parent = '$post->ID' AND post_status = 'inherit' AND post_type='attachment' ORDER BY post_date DESC LIMIT 1");

$post_thumbnailID = wp_get_attachment_metadata($post_thumbnail);

set_post_thumbnail($postID, $post_thumbnailID);
}

GOT IT!

// update the "12" to the ID of your form
add_filter("gform_post_submission_12", "gform_set_post_thumbnail");
function gform_set_post_thumbnail($entry){

    // get the last image added to the post
    $attachments = get_posts(array('numberposts' => '1', 'post_parent' => $postID, 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'DESC'));

    if(sizeof($attachments) == 0)
        return; //no images attached to the post

    // set image as the post thumbnail
    set_post_thumbnail($postID, $attachments[0]->ID);
}
