php variable passing issue

squibs

I've got a new install of php 5.0.4 running with IIS6 on win 2003 server. register_globals is off. Variables are not getting out of my form. Even with a simple exampl I snagged off the net (see below) I get

"Notice: Undefined index: Number in c:\Inetpub\wwwroot\admin\test.php on line 2
The number is

---

>"

Any ideas?
Thanks.

> Script name : test.php <

---

<?php
echo "The number is

---

>" . $_POST;
?>

---

> Script Ends <

---

---

> Script name : form.php <

---

<?php
echo "<form method=POST action=\"./test.php\">
<input type=text name=Number size=20>  <input type=submit value=\"Submit\"></form>";
?>

---

> Script Ends <

Hrm, try this as your whole PHP page:

[php]<?php

if ( $_SERVER == "POST" )
{
echo "The number is

---

>" . $_POST;
}

echo "<form method=\"POST\" action=\"test.php\">
<input type=\"text\" name=\"Number\" size=\"20\">
  <input type=\"submit\" value=\"Submit\">
</form>";
?>
[/php]

You could also try print_r ( $_POST ); to debug.

Serbian,
I tried your script - same result: undefined index
I the added print_r ( $_POST ); to the bottom of the script.

It gives Array ()

:eek:

Try stick in

[PHP]foreach($_POST as $key => $val) print("$key => $val<br>");[/php]
This line always comes in really handy for me when troubleshooting.

squibs

That foreach statement outputs nothing, unfortunately. I'm now suspecting my php install. I didn't mess with php.ini much though....

seamus

Actually I never looked at your form code.

To satisfy my curiosity, try replacing
<input type=text name=Number size=20>

with

<input type=\"text\" name=\"Number\" size=\"20\">

print_r does essentially the same thing, you just can't do custom formatting with it.

It's an odd one alright. Reinstallation of PHP might be an idea alright, are you on a windows or Unix machine?

Seamus - I'm at home now ( it's a problem on a machine at work) so I'll try that on Monday and let you know. Thanks!

Serbian it's a windows machine.

Your form is USING POST, right? You might want to try using $_REQUEST instead of $_POST, btw; it contains data from GET, POST and cookies.

Your script looks ok, but I've always had trouble with PHP on IIS. Have you tried Apache?
Also, out of curiosity, try turning on register_globals and see if a global var works.
Presumably regular variables work ok?

squibs

rsynnott - that worked. Thank you

I still don't understand why $_POST would pull data from method="post".
Out of curiosity, can you suggest why? A vagary of IIS.

Sico, I'll be running multiple sites (throught different ports) off this server, and I'll also be serving ASP pages. I'm not comfortable attempting that with apache. Thanks for the help though.

No, it's standard. $_GET is populated with GET requests, $_POST is populated with POST requests, $_COOKIES is populated with cookies, $_REQUEST is populated with all three. I think the original reasoning was to stop people trivially overriding cookies.

squibs

That should have read "I still don't understand why $_POST WOULDN'T pull data from method="post". I get that REQUEST does all three, but if that works, surely POST wouldtoo, assuming method was post?

rsynnott

Yes, it would, if method WAS post

squibs

But it didn't
Using $_POST and method post I got not a sausage. I just switched to $_request, leaving method="post" and the data came thru.No other changes - weird.
