checkbox, $_SESSIONS - right mess !

Mad_T

Hi
I have simple single page form with a couple of check boxes.

If a checkbox is set then a session is enabled.
When I reload the page I would like the checkbox to show if it's set or not.

Likewise if the checbox is unset, I'd like to unset the session.. and have the checkbox reflect this.

This is what I have so far :
the check box is named 'cb'

if (isset($_POST['cb']))
{
$_SESSION['cb']="on"; 
$cb="checked";
}else{
unset($_SESSION['cb']);};

<input type='checkbox' name='cb' value='ON' $cb>

Obviously it's not working.. can anyone point me in the right direction.

Thanks

Is this the entire code? If not, are you sure you have a call to session_start() somewhere before any output?

sorry yes I have session_start()

I'm not sure how you're echoing out your input field but I think you want your $cb value to look like the following:

$cb = 'checked="checked"';

Otherwise, you're just putting the word 'checked' into you checkbox field. You need the checked attribute to be set to 'checked';

the actual code you're using? If so, then the problem should be obvious - you've got some HTML markup in the middle of PHP code.

There's also a semicolon after the else branch for some reason, unless that's some obscure yet valid PHP syntax I am unaware of.

Thanks for the replies. My example is a bad case of copy & paste.. = mess !!

What I'm trying to do is simple.
Have a checkbox that when ticked it sets a session.
When unticked it unsets the session.
I would also like the checkbox to be 'checked' is the session is set, un checked if it isn't.

I'm trying to do this within one page.

Thanks for your patience..
