Add a new page in admin

[kesaven]

Hello

 

I am trying to add a new page in admin but with no success:

Here are my prestashop details:

 

Version: 1.4.8.2

 

I copied an existing admin tab and added the following code:

 

<?php

include_once(PS_ADMIN_DIR.'/../classes/AdminTab.php');

class GestionDates.php extends AdminTab
{
public function __construct()
{
// Initialise the tab by linking it to a database table and setting its default permissions

parent::__construct();
}

public function postProcess()
{
// This function is executed when the Submit button is clicked
// Use it to store the value of text fields in the database

parent::postProcess();
}

public function displayForm($token=NULL)
{
// This function can be used to create a form with text fields
echo '<span>Test Span</span>';
echo 'sadadasdasdasd';
}

public function display()
{
// This function can be used to create a form with text fields
echo '<span>Test Span</span>';
echo 'sadadasdasdasd';
}

}
?>
 

However I still have a blank page

Can anyone help me out please

 

Thanks in advance
