      Hi rafi83, and welcome to TSDN.

      Calling PHP functions directly from JavaScript is not possible.

      This is because PHP code is executed on the server, before the HTML is sent to the browser.
      Javascript on the other hand is executed by the browser once the HTML has reached the client.

          Heya, rafi83.

          To add to Atli's post, you can use JavaScript to create an AJAX call that loads a script to call the function.

              u can only call ur .JS function by saying:$btnname->setOnclick("re turn validDelete()") ; this will only show the dialog and will also delete even if u press Cancel. u wil have to use Ajax for this.
