Hello. I have a form that I would like to use checkboxes. ... snip ... I've been told that if I want to manipulate each one then I should use 'name=checkbox[]' and make an array out of it. okay, fine. but how do i access them in my PHP script? I know I have to use the $_POST[] array, but this creates a multidiminsional array, yes? do i access it like $_POST[checkbox[1]]?? or $_POST[checkbox][1]??

The latter. But note, if a box isn't checked, it's not going to be sent, so won't be in the array. <form> <input type="checkbox" name="StateID[]" value="32" /> NV <input type="checkbox" name="StateID[]" value="33" checked /> NH <input type="checkbox" name="StateID[]" value="34" checked /> NJ </form> In this case $_POST['checkbox'][0] would be 33 and ...[1] would be 34. Sometimes it's handy to identify the key upfront: <form> <input type="checkbox" name="StateID[32]" value="608" /> NV <input type="checkbox" name="StateID[33]" value="2" /> NH <input type="checkbox" name="StateID[34]" value="40" checked /> NJ </form> That would yield $_POST['checkbox']['34'] = 40. A nice way to handle incomming checkboxes is this: while ( list($Key, $Val) = each($checkbox) ) {

      #  do what you need to do...
      #  for example, show what was sent...
      echo "<br />$Key = $Val\n";

}

Just one thing, as someone noted a week ago or so, you can't use the [] syntax *and* javascript. If you also need to process your checks from jscript side you shall resort to some older method and have your variables called like <input type="checkbox" name="StateID_32" value="608" /> NV <input type="checkbox" name="StateID_33" value="608" /> NV then process it with variable variable names (the $$ syntax). пока Альберто Киев @-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@-_=}{=_-@ LoRd, CaN yOu HeAr Me, LiKe I'm HeArInG yOu? lOrD i'M sHiNiNg...
