Hello,

I think I have an easy problem. My current form looks like this:

Depending on the chosen Dropdown item I want to show the user different data. My code looks like this:

public $SkriptanmeldungenAll;

function doSubmitDruckliste($data, $form) {
//some code
$this->SkriptanmeldungenAll = DataObject::get("Skriptanmeldung","SkriptID = '$SkriptID'");
//...
}

function GetSkriptanmeldungen()
{
return $this->SkriptanmeldungenAll;
}

An the template looks like this:

...
<% control GetSkriptanmeldungen %>
<tr style='height:30px' >
<td>$Nachname</td>
<td>$Vorname</td>
<td></td>   
</tr>
<% end_control %>

But if I try to use the button "Anzeigen" no data were shown, because the variable $this->SkriptanmeldungenAll is empty.
What can I do to display the data?

I also tried this way:

function GetSkriptanmeldungen()
{
if($_POST['SkriptID'])
{ // return the data }
}


But I think the $_POST - Variable isn't be setted.

Can anyone help me?

Best regards, Beppo

When you are sure the form data is valid, you can save the ID in a session.

Session::set('SkriptID',(int)$data['SkriptID']);
Session::get('SkriptID');

If you're looking for a cookieless option, you can also use GET parameters via controller.

Or if a login to your service is required, you can also save the ScriptID & Member::currentUserID() in a DataObject.
