Populate a Custom Field with {entry_id}

Just type that in to the default value for the custom field. It may not be available in the drop down of merge tags, but it will work. I just did it and it worked for me. The post custom field holds the entry ID. One anomaly is that the field in the entry continues to hold the default value of {entry_id} but that does not matter much, since you have the entry ID available in the ID already.

Here is the form I tested on:

After you submit, you will have a link to the category, and the most recent post will be yours. At the bottom of your story submission, you will see This was entry #971 where the 971 is your actual entry ID. Here is a post I created using this form. You can download a copy of the form here http://pastebin.com/0dFB3Yp1 (select the raw or download link.)

Your experience was different than mine. What you want is exactly what I did. The entry ID was stored in my custom field. Can you please send me a WordPress admin login for your site and I will take a look. Thanks.

I received your email. To store the entry ID as a custom field in the post, not just use the entry ID in the post, you can use the gform_after_submission hook. See this code:

[php]
add_action('gform_after_submission_9', 'save_entry_id', 10, 2);
function save_entry_id($entry, $form){
    update_post_meta($entry['post_id'], 'gfentryid', $entry['id']);
}

That will write the entry ID to a custom field with a meta key of "gfentryid" and save it with the post. Then you can do whatever you want with it in your template. Change the 9 in line one to your form ID.

Also, you can delete the hidden field and the reference to it in the content template.

You're welcome. Sorry I missed it the first time around.
