Checkbox

nmj001 · July 25th, 2003, 03:13 AM

When doing the exercise on p83 my results are not the same as in the book. On my php page I get this:

onChoice=on

My code is this:

<html>
<head></head>
<body>
<FORM METHOD=POST ACTION="checkbox.php">
Have you ever eaten haggis before?
<INPUT NAME="Choice" TYPE="CheckBox">
<br>
<br>
<INPUT TYPE=SUBMIT>
</FORM>
</body>
</html>

<html>
<head></head>
<body>
<?php
echo $Choice;
?>
</body>
</html>

Please can someone tell me why?

to get variable to show (assuming global variables are turned off):

<html>
<head></head>
<body>
<?php
$Choice = $HTTP_POST_VARS['Choice'];
echo $Choice;
?>
</body>
</html>

Or a wee bit shorter:

<html>
<head></head>
<body>
<?php
$Choice = $_POST['Choice'];
echo $Choice;
?>
</body>
</html>

Where's onChoice coming from??

From what I can gather onChoice means that the check box has a check in it so choice is on. But this was with Global Registers OFF. Once I switched to Gobal Registers ON I haven't had any more trouble. But I am wondering what to do in the future when I have to work with them OFF all the time?

Chapter 8 talks about session variables. You'll be fine until then with these (depending on POST OR GET method):
$Choice = $_POST['Choice']; or
$Choice = $_GET['Choice'];

Cool thanks will use this until I eventually reach Chpt 8! Fingers crossed!

Its often helpful to know just WHY the PHP group changed the register_globals directive to off in the first place... this is explained in detail on the php.net website.

See Nik's register globals FAQ, Nik does a fine job of explaining the security issues with register_globals and why you should use the new superglobal arrays.
http://p2p.wrox.com/archive/beginnin...2002-11/17.asp

And as always, read the php manual:
http://www.php.net/manual/en/languag...predefined.php

It is going to be much easier for all you newbies out there to adapt to using php with the register_globals directive turned off, instead of taking the easy way out and just turning it back on in php.ini. For one the directive is deprecated, which if you aren't familar with the lingo means slated for deletion from the language all together. So in some future version of php this functionality won't even be available.

Just my two cents!
