How do I pass data from checkboxes in a form using PHP?

The trick is to make the name of the checkbox an array:

<input type="checkbox" name="my_check&#91;1&#93;" /> 1<br />

  <input type="checkbox" name="my_check&#91;2&#93;" /> 2<br />

ETC.

and then process it on the page you send the data to like:

if (is_array ($my_check)) {



    while (list ($key, $value) = each ($my_check)) {

      $data .= "$key, ";

    }



  }

Adapt the name and who you want the data outputted and you'll be away.

---------------------
Note:

You can also set the values this way too (I'm not aware of any differences in performance between the 2 methods):

<input type="checkbox" name="my_check&#91;&#93;" value="1" /> 1<br />

  <input type="checkbox" name="my_check&#91;&#93;" value="2" /> 2<br />

ETC.
