problem: ajax call v.s. opening page directly

qmqmqm · 03-10-2009, 09:13 PM

if I open the php file directly, it will generate the "mytest" file.
If I use ajax to call the php file however, SOMETIMES it works, but other times the "mytest" file will not be generated.
However I do receive the "hi" back from the ajax call every time.

Does anyone know why this is?

Code:

<?php

$profile_name=$_GET["my_name"];


$file_path = "/mytest";

$file=fopen($file_path, "w");

fwrite($file, "test...");

fclose($file);

echo "hi";

?>

My Ajax call is copied from w3schools, and shouldn't be a problem. I also used the ajax function in jquery and the same problem.

BTW I am using windows XP and IE, running xampp as my webserver and sql on localhost.

If anyone can give me some advise it would be greatly appreciated!

Thanks,

Tom

Sounds like you are probably cached.

Code:

xmlhttp.open("GET", theURL ,true);
xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");
xmlhttp.send();
