Try this...create a test page by copying the codes below and save it as delete.php

 <script type="text/javascript">
function check(){
var r = confirm("Are you sure you want to drop this appointment?!");

return true;


alert("The appointment will not be cancelled");
return false;


<a href="delete.php?delete=yes" onclick="return check();" />Delete</a><br/>


 ## this is where you put the deletion, but make sure to get the right info.
 echo "Appointment has been cancelled";


Codes above should mimic the process with alert and confirmation ..Then should echo Appointment has been cancelled, if choose to drop appointment. I hope you are seeing the pattern here when javascript is used along side with php. Php will not wait for this "alert("The appointment has been canceled!");".. Unless, you make a switch or if statement to confirm that the delete value has been passed.

However, the javascript will be responsible for allowing the href to get through and therefore, setting off the isset to true. Observe closely, when the prompt is on, the url of the page is at default, but when you confirm the delete, the url goes to delete.php?delete=yes, and that is the triggering mechanism for the php script. Making this if(isset($_GET['delete'])) equal to true.
