Re: [nmsinc] Undefined index error
Hi nmsinc,
Checkboxes are the only kind of html form field that don't submit anything at all if they're not checked. What I usually do is use a hidden field field like this:
<input type="hidden" name="view_map" value="0" />
<input type="checkbox" name="view_map" value="1" />
If you have two fields with the same name then the value of the last one is used. So if checked you'll get view_map=1 and with unchecked you'll get view_map=0
Another trick is to use @ which suppresses errors and warnings in php. So instead of $_REQUEST['view_map'] use @$_REQUEST['view_map']
Also, note that we use $_REQUEST, which has both $_GET and $_POST in it, which is why changing $_POST didn't make a difference.
Hope that helps, either of the above two solutions should fix it. Let me know if you have any other problems.
