_GET, _POST vars empty with Querystring

[HarpDog]

Hello,

I am running PHP 4.39 as a CGI under Tomcat 5.025, Linux 2.4.20-31.9.
Configure = './configure' '--with-java=/usr/java/j2sdk1.4.2_04'
'--with-servlet=/home/www/jakarta-tomcat-5.0.25' '--with-mysql'

The $GET and $REQUEST are empty even though I can see the query string values in the URL as in:

http://localhost:8080/ip7/httptest.php?var1=212122&var2=343434

My HTML is very simple:

<form action="http://localhost:8080/ip7/httptest.php" method="get">
<input type="text" name="var1">
<input type="text" name="var2">
<input type="submit">
</form>

The PHP program httptest.php is also very simple:

<?PHP

if(!empty($REQUEST['var1'])) { $var1 = $REQUEST['var1']; }
else { $var1 ='undefined'; }

if(!empty($GET['var2'])) { $var2 = $GET['var2']; }
else $var2 ='undefined';

// Various HMTL tags removed for simplicity
echo $var1
echo $var1
?>

I have tried everything I can think of including using HTML POST instead of GET, setting register_globals = On/Off.

$_SERVER[QUERY_STRING] shows me the values I need.

$HTTP_GET_VARS['var1'] also returns empty string.

What is the problem here?

Thanks in advance.

make sure track_vars is on in php.ini, but i dont even think $_SERVER would have any values if it wasnt... odd problem

have you tried isset() ? im just wondering if the variables are set, but no value for some reason(making !empty() evaluate to false), or if they just arent even set

I tried isset() but they are not being set. Very perplexing....
Someone else suggested I add

print_r( $GLOBALS );
print_r( $HTTP_GET_VARS );
print_r( $HTTP_POST_VARS );

an review the results. THis is what is returned:

Is this is CGI problem? I don't understand why all the $_GET is empty yet the QUERY_STRING shows a values.

Any help appreciated.

[rehfeld]

yeah thats what was confusing me too....

i never checked the source code, but i was always under the impression all post get cookie data etc.. was all passed to php raw, and php parsed it into individual variables etc...

which would make you wonder why does query_string have the data but not _GET

the only thing i can think of to explain that, is that maybe query_string is passed to php as an environment variable(for example i know apache has that variable available)

so it seems like php isnt receving the regular data, only env variables. but at the same time ENV is empty too, but the GET values are in the argv array.....very odd

i dont understand much about how cgi works on the lower levels,
but i do know if for example your running php and use exec() to spawn another process and execute another php script, any values/variables etc that you pass in the exec() call are passed to the spawned php script through the argv array....just like whats showing in your var dump.

from what i understand about cgi, every request is a new process(unless its fastcgi), but i would think the webserver has a different way to pass variables to php running as a cgi than just argv. just seems like its acting like it wasnt meant to be run however it is your running it.

sorry but thats about the extent of my knowledge 😃
i would try reinstalling it and playing w/ diff config options, but maybe you understand cgi better and can troubleshoot futher.

good luck
