Gravity Forms field ID $entry not working

Question

So my script is simple right now just to test out the $entry field id's.

add_action("gform_after_submission_3", "set_post_content", 10, 2);
function set_post_content($entry, $form){
$subject = $entry["28"] . 'Applied as: ' . $entry["2"];
 mail( $emailremoved, $subject, $message);
}

Right now entry 28 is a dropdown, this one returns the selected value.

Entry 2 is the name field with split first and last. This returns nothing. Ive also tried $entry["2.1"] and get nothing.

Entry 34 (not added) is a multi checkbox. This value is not echoed out either.

This is a multipage form, but that shouldnt matter.

Any ideas why the values are not returning? They are saving to the form entry.

Answer 1

To debug you should print what's in $entry.

echo '<pre>' . print_r($entry,true) . '</pre>';
die();//You may need to kill the script to view..

Or email to yourself in your current mail function.

$message = '<pre>' . print_r($entry,true) . '</pre>';
