checkbox form help

[MDanz]

i have this in a loop and a form

<input type='checkbox' name='$topic' value='No' />

 

on the page the form directs to.  How do i get each separate topic that has been checked?

[PravinS]

Give array name to checkbox like name="topic[]" and assign some value to it. When form is posted you will get checked values in array format.

but how do i keep the $topic variable.

 

do i do this? 

$topic[]
