Seeing if checkboxes are ticked?

[Shibby]

I have a form that's been submitted with a large amount of checkboxes on. I want to find out if they are ticked. But they have a dynamic name such as subtopic1, subtopic5, subtopic24 etc.

So how can I find out which have been ticked?

Loop through all the checkbox names $POSt['checkbox1'], $POST['checkbox2'], etc. (look up variable variables in the manual). If they're set, the checkbox was ticked.

The names were dynamic so that wouldn't have worked but never mind I found a way now.

do a simple if isset...

if (isset($_post['check_box1'])) {
print "Check Box was clicked";
}
else {
print "Check box not clicked"
}

html looks like...
<INPUT TYPE="CHECKBOX" NAME="check_box1">

this will check if the check box is clicked.
