Change the submitter user of an existing form

I am using Gravity Forms with wpDataTables to display entries to users who can then edit/modify the data that was submitted via Gravity Forms. wpDataTables has a means of limiting the records displayed to only the user who submitted the form. This works great… EXCEPT when that user leaves the company and they want a new user to manage the data.

Is there a way to edit the user submitted id and assign it to another user? I have searched a bit and find that GravityViews does this, but I am loathe to add yet another plugin, particularly a powerful one like GravityViews, when all I need is this one little feature.

You can definitely update the user ID associated with a Gravity Forms entry without using a plugin like GravityViews. To do this, you can create a custom code snippet to handle the update process.

Here’s a code snippet that demonstrates this process:

add_action( 'gform_after_submission', 'update_entry_user_id', 10, 2 );

function update_entry_user_id( $entry, $form ) {
    // Get the new user's email address or user ID from the submitted form data.
    $new_user_email = rgar( $entry, 'input_1' );
    // Query the database to find the user ID associated with the new user's email address or user ID.
    $new_user_id = email_exists( $new_user_email );
    // Update the entry's user ID field with the new user's user ID.
    GFAPI::update_entry_field( $entry['id'], 1, $new_user_id );

I hope this helps! Let me know if you have any questions or need further assistance.
