The GET-arguments (?)
|
|
| Henk Oegema 2006-06-19, 7:02 pm |
| I have just started teaching myself PHP language.
I'm studying an article about "GET", to pass arguments from one page to
another.
It is not working the way it is suppose to.
And I can't figure out what the problem (mistake) is.
This file should pass a argument to the file baseball.php
========================================
==============================
<html>
<head>
<title>A GET example, part 1</title>
</head>
<body>
<form action="http://192.168.123.100/PHP4/baseball.php" method="GET">
<p>Root, root, root, for the:<br>
<select name="Team" size=2>
<!-- It's a good idea to use the VALUE attribute even though it is
not mandatory with the SELECT element. In this example, it's
extremely necessary. -->
<option value="Cubbies">Chicago Cubs (National League)
<option value="Pale Hose">Chicago White Sox (American League)
</select>
<p><input type="submit">
</form>
</body>
</html>
========================================
===============================
File baseball.php:
========================================
===============================
<html>
<head>
<title>A GET example, part2</title>
<style type="text/css">
<!--
body {font-size:24pt;}
-->
</style>
</head>
<body>
<p>Go,
<?php print("$Team"); ?>
!
</body>
</html>
========================================
==================================
If the user makes a selection and presses SUBMIT in the first file, than the
browser put those elements together, without spaces.
The following URL string should be made:
http://192.168.123.100/PHP4/basebal...&Submit=Submit.
So the output should be: Go, Cubbies!
However, what I get is:
http://192.168.123.100/PHP4/baseball.php?Team=Cubbies (&Submit=Submit is
missing !
My output is: Go, !
The variable output is missing.
After many hours of searching I still haven't found the problem.
Thanks for any help.

| Using PHP with it's current version, register globals is disabled by
default.
Therefore, any variable passed by the user (POST, GET,...) is only
accessible by using the global arrays $_GET or $_POST.
try this
echo $_GET['Team'];
PS you should also review your html...

Hi Henk, couple of issues here:
1) to pass the Submit variable you need to name the Submit element:
<input type="submit" name="Submit" value="Submit">
2) instead of printing $Team try printing $_GET['Team'].
It sounds like register globals are turned off (as they should be) and you
need to access request variables through the appropriate superglobal array
(in this case $_GET - if the form used the POST method you would use the
$_POST array). Please see: http://uk2.php.net/register_globals
cheers

The mistake was from the book(PHP4 Bible, Tim Converse and Joyce Park (Dutch
translation))
The line input="submit".......was incomplete !!
