Using a link to change page content

[dankine]

Well phrased topic I know.

 

Basically I have a page to enter data into a mysql db via a form. After the data has been input, this form disappears and instead (on the same page) the data is shown in the same format, just not editable anymore.

 

What I need to do is have a link that will be able to switch between the two states, being 'edit' and 'view'.

 

Can anyone help point me in the right direction?

It would be very much appreciated.

<?php

  if (isset($_GET['action'])) {
    $action = 'view'; // default.
  } else {
    $action = $_GET['action'];
  }

  if ($action == 'view')) {
    // display data
    echo "<a href='?action=edit'>edit</a>";
  } else {
    // display form
    echo "<a href='?action=view'>view</a>";
  }

?>
