Get variable value client side passed from server side

Hi,
In my login page I’ve had a SELECT to get additional information during login. My code for that :

$("#password").parent().parent().append(
        '<div style="margin-top:20px;" class="form-group"><label>Sélectionnez ... : 	  </label><select id="an_scol"  name="an_scol" class="form-control ewControl"></select></div>'
    );

Now in my Server Events ->Global → Other → Login Page ->Page_load, I set my variables

    if (!empty($_POST["an_scol"]))
        {
            SetClientVar("SelectedAn", $_POST['an_scol']);
        }

But I got undefined when I try to call my variable client side. In Clients Scripts ->Global ->Pages with header/footer → Client Script :

        var selectedAn = ew.vars.SelectedAn;

    	if(ew.vars.login.isLoggedIn){
		$('<div id="myarea">' + selectedAn + '</div>).insertBefore($("#mycontent"));
		}

What’s wrong with my code ?Help please.

You may try to set the client variables in Page_Rendering server event, instead of Page_Load server event.

Then the variable only exists in Login page.

Hi mobar

You may try to set the client variables in Page_Rendering server event, instead of Page_Load server event.

But I don’t have a Page_Rendering event for login page ???
Trying my code in Server Events->All pages->Page_rendering I got a “Undefined index” error for my $_POST[“an_scol”] variable.
My intention is to get the content of my select (an_scol), added in the login page, as a session variable and be able to access it later on the client side.

Since Page_Rendering is for all pages, you will not find it under the Login page. You will see it from Server Events → Global → All Pages.

I managed to get a solution that works but I wonder if this is really the right way to do it ? ??In Sever Events->Global->All Pages->User_validated :

$_SESSION["SelectedAnId"] = $_POST["an_scol"];

And in Events->Global->All Pages->Page_Rendering :

if(isset($_SESSION["SelectedAn"])){
        SetClientVar("SelectedAn", $_SESSION["SelectedAn"]);
    }

I figure there must be a better way to do it.

Your code seems fine and it resolves your case.
