Remember Checkbox State..

[TomT]

Hi

I'm hoping someone can point me in the right direction.

 

I'm trying to create a single page that contains a couple of checkboxes.

When the first checkbox is checked I want to set a session.

When the second chechbox is checked I want to set a different session.

 

When the page submits ( to itself ) I'd like the checkboxes to reflect if they are checked or not.

 

I can sort of do that part,but I'm having major issues with unsetting the sessions and updating the checkboxes to reflect this.

 

Does anyone have a simple example on how to do this.

 

Many Thanks

The process is simple:

 

<input type="checkbox" value="foo"<?php isset($somevar) && $somevar == 'foo' ? ' selected="selected"' : ''; ?>>

 

If $somevar is defined and equals 'foo' your checkbox will be selected.

Another thing to remember with checkboxes is that only checked values are sent.

 

 
<input type=hidden     name='cb1' value='0'>
<input type=checkbox name='cb1' value='1'>

Thanks for the replies.

I can create the checkbox and get the value from it..

 

The problem I have is more with setting and unsetting the session and also showing the state of the checkbox depending how the session is set.

 

Can someone help with this ?

Thanks

$cb1_checked = isset($_SESSION['cb1']) && $_SESSION['cb1']==1 ? 'checked' : '';
$cb2_checked = isset($_SESSION['cb2']) && $_SESSION['cb2']==1 ? 'checked' : '';

echo "input type='checkbox' name = 'cb1' value='1' $cb1_checked /> CB1
echo "input type='checkbox' name = 'cb2' value='1' $cb2_checked /> CB2
