PHP loses session data

sean_mccoy

If the html in my page passes a reference to an image that is not found on the server (thus generating a file not found error in my apache error log), the session data in the /tmp/sess_? file gets blown away.

All of the variables are still in the session file. They are all just blank.

Is this a PHP configuraiton issue?

Thanks,

ummm could you make it a bit easier to understand, maybe quote some code?

Here is the test case that reproduces the problem on our configuration.

Session auto start = 1...with that said...

============================================
file1.php
<html><body>
<form name=body action="<? echo $PHP_SELF ?>">
<? echo $SESSION['sample']; ?><br>
<? $SESSION['sample'] = "FOO!"; ?>
<input type=submit value="Submit">

</form></body></html>

file2.php
<html><body>
<form name=body action="<? echo $PHP_SELF ?>">
<? echo $SESSION['sample']; ?><br>
<img src=some_non_existant_image.gif>
<? $SESSION['sample'] = "FOO!"; ?>
<input type=submit value="Submit">

</form></body></html>

1) browse to file1.php: you will only see a "Submit" button.
2) click submit: "FOO!" will appear followed by the "Submit" button.

This is good.

1) browse to file2.php: you will see a broken image link and a "Submit" button.
2) click submit: you still see the same thing.

This is not so good.

Symptoms:
The /tmp/sess_* file on the server contains "sample" as a registered variable, and never loses it. So the variable stays registered.

But when you execute file2.php, the value gets lost.

Hmmm.....

I find this odd; the fact that the web server can't find a particular GIF file that the client is asking for should not have anything at all to do with PHP....

Indeed, the test cases work for me; on initial page load I get an "Undefined index" notice I was expecting; subsequently both maintained their session data.
