$_GET Won't Work in PHP5?

benzrf

<?php
$t = $_GET["input"] . "<br />";
print $t;
?>

See anything wrong with it? Because when I go to

http://74.75.112.237:2000/phpteser.php?input=example(teser is a corruption of tester)

I get this error message:

PHP Notice: Undefined index: input in C:\WAN Accessable Directory\phpteser.php on line 8

See for yourself! By the way, if you can't connect, it's probably because my computer is off.

So, will someone please point out to me the error in my code?!?!?

Test with a "more correct" example:

<?php
if (isset($_GET['input'])) {
    echo 'The test input: ' . htmlspecialchars($_GET['input']);
} else {
    echo '<a href="' . htmlspecialchars($_SERVER['PHP_SELF']) . '?input=hello">test input</a>';
}

No, I can tell what the problem is by looking at the error. For some reason, it isn't accepting any input. It thinks that the value "input" was never passed to it.

laserlight

So, what output do you get with my example?

If laser's example isn't working for you, can you post an example of how you setup your form to pass the data please? (yeah it isn't connecting)

benzrf

Actually, when the form didn't work, I tried passing data to it directly using the URL. And it still doesn't work.

I haven't had time to test the "correct" version of the script, I'll see about it later... If I can't do it today(March 5), I'll probably be able to do it tomorrow.

benzrf

Ok, I've got it. It returns the link; that is, it's ignoring the fact that the input exists for some reason.

benzrf

Someone help me please!!!!!!!

I decided to do something about the problem with $GET myself, and I came up with function getrep(get replacement), which extracts information from $SERVER['QUERY_STRING'](which works for me for some reason, even though $_GET is malfunctioning). Here it is:

<?php
function getrep($namez)
  {
  $org = " " . $_SERVER['QUERY_STRING'];
  $aa = strpos($org,$namez);
  if ($aa != 1)
  {
  $aa = strpos($org,"&" . $namez);
  $aa = $aa + 1;
  }
  if ($aa == FALSE)
  {
  return "ERROR IN FUNCTION GETREP";
  }
  $bb = strpos($org,"&",$aa);
  $aa = $aa + strlen($namez) + 1;
  if ($bb != FALSE)
  {
  $cc = $bb - $aa;
  $res = substr($org,$aa,$cc);
  return $res;
  }
  else
  {
  $res = substr($org,$aa);
  return $res;
  }
  }
?>

The syntax(as you can see) is getrep("nameofthegetinfoyouwant"). That solves my problems with $GET, but what about $POST? It won't work for me either, and $POST isn't part of $SERVER['QUERY_STRING'].

HELP!!!

Please don't tell me that something in getrep is superfluous and that I should get rid of it; I spent an hour or two error-checking it and fixing it, and everything there is absolutely necessary for accurate GET data.

As in you click on the link in my example, and instead of getting the output beginning with 'The test input: ', you are shown the link again?

Actually, the whole getrep() function is superfluous since you should be able to use [man]parse_str/man with $SERVER['QUERY_STRING']. However, since the use of parse_str() with $SERVER['QUERY_STRING'] is supposed to be superfluous due to $_GET...

What is the exact version of PHP that you installed, and what web server software (including version information) are you using? It might not matter, but stating the version of Microsoft Windows might be useful. Also, tell us the steps you took to install your web server software and PHP.

benzrf

Yes, I'm shown the link again. I didn't make that clear? I had never heard of parse_str() before, so can you blame me for coming up with getrep()? Anyway, I installed PHP 5.2.9, and Xerver 4.32. As for installation of PHP, I just ran the installer and added the PHP folder to my system path. I have XP Professional.

No, it was not clear to me.

What makes you think that I am blaming you for anything?

I suspect that this is either a bug with Xerver 4.32, or a misconfiguration. Your best bet may be to completely uninstall both PHP and Xerver, and install them from scratch. If the problem persists, contact the Xerver community for help. My example script should suffice to demonstrate the effects of the bug or misconfiguration (e.g., it could be a mistake in their default configuration with respect to PHP).
