I have a simple form which I need the user to enter a postcode and that information then display on a specific template page.

My form looks like this:

// Directions Form
	function DirectionsForm() {
        // Create fields
        $fields = new FieldSet(
            new TextField('Postcode', 'Enter Postcode')
        );
		 
        // Create actions
        $actions = new FieldSet(
            new FormAction('doDirections', 'Submit')
        );
		
        $form = new Form($this, 'DirectionsForm', $fields, $actions);
		
		return $form;
    }
	
	
	function doDirections($data, $form) {
		Session::set('StartPoint', $data->$postcode);
		Director::redirect('get-directions/'); 
    }

The template I wish to display my postcode on, then looks like this:

function Postcode() {
		Session::get('StartPoint'); 
	}

And finally, the action to display the value is:

<% control Postcode %>
        <h2>My Postcode is: $data('StartPoint')	</h2>
<% end_control %>

I know I'm missing something fundamentally basic here, but my brain has blanked - can anyone point me in the right direction please?

Hey Chilli-D,

Multiple things are wrong here, hopefully this should work for you:

Code:

function DirectionsForm() { 
$fields = new FieldSet( 
new TextField('Postcode', 'Enter Postcode') 
); 
       
$actions = new FieldSet( 
new FormAction('doDirections', 'Submit') 
); 
       
$form = new Form($this, 'DirectionsForm', $fields, $actions);     
   return $form; 
} 
    


function doDirections($data, $form) { 
   Session::set('StartPoint', $data['Postcode']); 
   Director::redirect('get-directions/'); 
}

function Postcode() { 
   Session::get('StartPoint'); 
}

Template:


<% control Postcode %> 
	<h2>My Postcode is: $Postcode</h2> 
<% end_control %>

Thanks novaweb!

I worked this out late last night - however, you have been a little more efficient than me, so I will probably use this!
