  submit handler function should return false to prevent the form from submitting.

  so in your handler function you need to test and see if the checkbox is checked. if so, return true - (and the for will submit) otherwise return false (and the form will be prevented from submitting)

  So I'll assume you mean in javascript since you didn;t say.

  if (frm.insertboxname.checked == false) {
  alert ('** Error message **');
  return false;
  }

  Well, fugged, I put that into my page, and it doesn't seem to work. Even if the box is not checked, the form still submits, and the information goes into the database.

  • I'm guessing you neglected the part where the js is explicitly referencing the checkbox by id– acescence1/2

    No, I put the ID into the js. Where it says "foo." Right?– boobs2/2

  make sure you don't have any other javascript errors going on. if you have a url, I can help you debug what's going on.

  Can always do it server side:

  HTML:
  <form action="formProcessor.php" method="post">
  <input type="checkbox" value="yes" name="checkbox">
  <input type="submit">
  </form>

  PHP (asp or asp.net works the same):
  <?
  if ($_POST['checkbox'] == "yes")
  {
  // process rest of form
  }
  else
  {
  echo "please check the box";
  }
  ?>
