I needed to show some preexisting data from a table and but needed to disable them to prevent user from editing them. So i disabled them
$form -> getElement(\"e
This is by design, disabled elements do not get submitted with the form.
What you are doing is actually a null practice, no matter what you do to that form in put it will be editable by the end user. You simply cannot trust form input - even hidden fields - to not be tampered with.
Your best bet is to just display the information to the user and load it again after the form has been submitted; at worst store it in a session.
