I have created new module, which populate information from database. this information will be displayed inside the grid. when the specific record is click light popup will be display.new PHP file is (showdetails.php) assigned to light box.
<td><a class="modal" href="showdetails.php" rel="{handler: 'iframe', size: {x: 680, y: 370}}" >POPUP</a></td>
POPup working fine. but inside popup, i am not getting " Not Found " error.
What is the rule to follow for popup or external file access.
showdetails.php contain below code
defined('_JEXEC') or die; echo "Hello world";
