PHP for form checkbox persistence

[Artie_J]

Hi all. I'm new to programming, and I was looking on the web for handling form checkboxes, specifically keeping them checked when either passing the name as a variable to another page, or when refreshing a page.
I reasoned out a simple method that I didn't see posted anywhere else, so I thought I'd offer it for review.

<?php
if($chkbox=="on"){
$chkswitch="checked='checked' value='on'";
}
?>

<form method="post" action="<? echo $PHP_SELF;?>" name="anything">
<input type="checkbox" name="chkbox" <? echo $chkswitch;?>>
<input type="submit" value="Submit" name="submit">
</form>

I'm using this sending and receiving "chkbox" from a MYSQL database also. Everthing works great!

Hi Artie_J,

Welcome to WebmasterWorld.

<input type="checkbox" name="chkbox" <? echo $chkswitch;?>>

I use:

<input type="checkbox" name="chkbox" value="on" <? if($chkbox==="on") { echo "checked"; } ?>>

It just keeps things that effect the checkbox all in one place, so if I want to make adjustments I can find it easily.
