field switch to disabled unless the correct logged in user

How to disable a form field for non-admin users.

Overview

The issue occurs when a form field should only be editable by a specific logged-in user, such as an admin.
Add a condition in the form's extra parameters to check the current username and output the disabled attribute if it does not match the required user.

Hello, sorry for the English, for it may uncle google.

Hi David,

Please try this code in the "Extra params" box:


<?php
$user = JFactory::getUser();
if(!$user->get("id")){
echo 'disabled="disabled"';
}

Thanks so much for your advice, it works perfectly. I modified it a bit.

<?php
      $user = &JFactory::getUser();
      $uzivatel = $user->username;
      if($uzivatel != "admin"){
      echo 'disabled="disabled"';
}
