Cannot send parameters

**code green** · Nov 5 '08, 12:38 PM

There is no such variable as $name; [PHP]if (isset($_GET['name'])) {
print "Hello, " . $name; [/PHP] Unless you have GLOBALS switched on, which you shouldn't,
you need to read the URL variables into the variable [PHP]$name = $_GET['name'])) [/PHP]

Hey, I saw that error in the code and fixed it right before you responded. However even when i use
[PHP]
$name = $_GET['name'];
print $name;
[/PHP]>

I still get nothing...

Also, here's the readout i get for the line that should set $name = to $_GET['name']
"Notice: Undefined index: name in C:\Program Files\Apache Software Foundation\Apac he2.2\cgi-bin\ch6ex.php on line 9"

So i see it being passed in the url, but it's like it's not ending up in $_GET...

Then I suspect your HTML [PHP]else {
print <<<HTML
<form action="http://pladdypants.hom e/cgi-bin/ch6ex.php" method="get">
Name: <input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
HTML; [/PHP] I don't understand how this

runs fine

.
How are you writing to the browser?
PHP - No quotes
HTML - No closing php tag
Or that other method of bulk printing with the <<< syntax

Hi again,
1) By 'runs fine' i mean it actually runs without critical errors that kill it.
2) I'm trying to write the end result (Hello, 'name') to the browser just using
[PHP]
print "Hello, " . $_GET['name'];
[/PHP]
So, i either want the browser to show my simple form, using the here document (HTML), or if it has a value from the form, to just print "Hello, " $_GET['name'].

The php script i posted originally is the entire script - is that missing something critical that i've overlooked, like end quotes, or end tags?

thanks again, -pladdy

Hi.

There are few things that jump at me when I consider you code.

Line #1.
If this is in fact being run through a Apache server, this line shouldn't be needed. The Apache server should know where the PHP executable is and know to execute .php files using it.
I'm not sure if this actually matters, but I thought it worth mentioning :)
Line #8.
Why do you *print* a HTTP header to the output?
It shouldn't be sent as a header, but it could be throwing the browser off, which might be causing some problems.
Line #15. The action property of your form.
I assume this URL work on your local network?
If you are using your own computer to host this, try changing it to:
Code:
```
http://localhost/cgi-bin/ch6ex.php
```
Again, I don't know if this will actually change anything, but this is what one typically does to connect to a local HTTP server.
And lastly, why do you use the GET protocol? Is the name value being passed on the URL as it should?
I would try using the POST protocol instead, and of course using the $_POST super-global rather than $_GET.

Hey there,

Line #1.
I removed the shebang but then it won't run, so i put it back.

Line #8.
I tried removing this and just putting the following code:

[PHP]
#!C:/Program Files/PHP/PHP.exe
<?php
error_reporting (E_ALL);
ini_set('displa y_errors', true);
?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>PHP Test</title>
</head>
<body>

<?php
//print "Content-type: text/html\n\n";

if (isset($_GET["name"])) {
print "Hello, " . $_GET["name"];
}
else {
print <<<HTML
<form action="http://localhost/cgi-bin/ch6ex.php" method="get">
Name: <input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>
HTML;
}
?>
[/PHP]

But this generates a 500 error and my browser won't open it. I checked the error logs and it's due to a malformed header.

Line #15.
I changed this and it's working fine.

Finally, i'm using get so i can verify that the parameter is being passed which it is. I'm just confused as to how i'm messing this up so badly. It seems from everything I read most people don't have any issues with getting parameters to pass in a script as simple as this.

**Atli** · Nov 6 '08, 02:30 AM

Thats all extremely odd.
I have never heard of Apache needing anything like that first line in order to work.

Try this script. See what it does:
[code=php]
<pre>
<?php
print_r($_GET);
?>
</pre>
<form action="?" method="get">
<input type="text" name="test"><br >
<input type="submit">
</form>
[/code]
Very simple, but effective.
If your server is working properly, this should simply print GET variables at the top.

**pladdypants** · Nov 6 '08, 03:22 AM

Hey again,

I tried it twice, here are the error outputs from error log:

[Wed Nov 05 22:13:01 2008] [error] [client 127.0.0.1] (9)Bad file descriptor: don't know how to spawn child process: C:/Program Files/Apache Software Foundation/Apache2.2/cgi-bin/Text1.php

...added a shebang line and got this error:
[Wed Nov 05 22:13:45 2008] [error] [client 127.0.0.1] malformed header from script. Bad header=Array: Text1.php

So i changed the code to this, and it runs but no parameters pass:
[PHP]
#!C:\Program Files\PHP\PHP.e xe
<?php
print "Content-type: text/html\n\n";
print_r($_GET);
?>
<form action="?" method="get">
<input type="text" name="test"><br >
<input type="submit">
</form>
[/PHP]

It outputs "Array()", then the input and submit button.

Perhaps this all means i set up apache poorly? I installed it from a windows installer and have done little to the config files. Really my only goal was to create a basic local server to learn php...

**Atli** · Nov 6 '08, 03:34 AM

Yes. This would mean that it is in fact your Apache server that is causing the problem.

How did you install PHP, and what version did you install?

On the rare occasions that I set up PHP on a Windows machine, I usually just use the MSI installers. I set up Apache first and then have the PHP installer set up the Apache config for it.

You can try editing your Apache's httpd.conf file.
Adding these lines at the end might help:

Code:

PHPIniDir "C:/Program Files/PHP/"
LoadModule php5_module "C:/Program Files/PHP/php5apache2_2.dll"
AddType application/x-httpd-php .php

Remember to change the paths to if they don't match your setup.

Thread title changed from "parameter wont send (newbie error, sorry)" to "Cannot send parameters" .This will be better than earlier. Please read the posting guidelines provided in FAQ section.

Are you actually running this in localhost?

**pladdypants** · Nov 6 '08, 01:00 PM

Adding in PHP/Apache versions

Hey everyone,

I read posting guidelines, thank you for changing the title. I made the changes suggested by Atli. Code Green, I am running this as localhost. Unfortunately I'm still not getting any parameters passed. I think the consensus is it has to do with the Apache setup. Unless anyone has other suggestions, perhaps I should post on the Apache forum?

I installed Apache 2.2.10 first, then PHP 5.2.6. I used windows installers for both. When they installed I just selected all defaults. Php set up apache, and when prompted i selected the 2.2x option. Hope this helps,

Thanks again all,

-Pladdy

**pladdypants** · Nov 12 '08, 02:15 PM

It was a setup error in the php.ini file. I was placing the php files in the cgi-bin folder of my server rather than htdocs folder. Once the scripts are moved to htdocs they work fine. Thanks all for helping me look in the right direction.
