I am using a loop to set all my $_POST form variables as $_SESSION variables.

Unfortunately, when I have a checkbox that is supposed to be unchecked (no value), it now has a value of 'on' when I echo the $_SESSION variable.

Form Code:

<input type="checkbox" name="comoff1-first" value="true" onclick="enabler(this, 'comoff1', 1)">

PHP Code:

if (isset($_POST)) {
foreach ($_POST as $key => $val) {
  if ($val != "Submit")
   $_SESSION["$key"] = $val;
}
}
echo $_SESSION['comoff1-first'];

Why is the value of $_SESSION['comoff1-first'] set to 'on' instead of empty, when it is unchecked?

Thanks.

I think that value of "true" is only submitted if the checkbox is checked.

Right. Maybe problem is in onclick="enabler(this, 'comoff1', 1) what run some javascript, isn't it? This form below must working correct.

<form name="form1" method="post" action=""> 
<input type="checkbox" name="comoff1-first" value="true" />
<input class="padding" type="submit" name="submit" value="Submit" /> 
</form>
