Why doesn't this work any more? (assuming the code is inside of test.php)

<a href="test.php?table=oral">ORAL</a>

<?
print("$table");
?>

It used to work for me on an older server. But now it says no variable is defined for $table when you click on the ORAL link. WTF?

azguy

globals is off. use $_GET["table"] instead

StuartD

Because on the new server, global variables are probably turned off.

which means that if you pass something in the url, you have to get it like this:
$_GET[table];

and if you pass it in a form, it's like this:
$_POST[table];

Correction. This is a "not so easy php question" now isn't it

Thanks azguy - I knew it had to be something incredibly simple

azguy

you can also turn on register_globals in your php.ini if you want

fuzebox

If you're lazy you can also use $_REQUEST if you don't feel like differentiating between _GET and _POST.

kemp

Dang, you guys post quick. lol

kemp

Is there any speed differences (assuming this page will one day get 500k a day)?

azguy

you wouldn't feel it even if there was

dubsix

I can't believe people still don't know abou register globals... it's been off in php by default for what 1+ year now?

azguy

Since v4.2.0, yeah.

StuartD

uhmm... not everyone who deals with php is a programmer... and not all programmers have been working consistantly for years.

There's people out there who don't deal with a bunch of code day in and day out, they don't have to deal with this stuff. That's what diversity is all about.
