HI, i want to check if the user filled the all inputs in the form. So, I
checked NULL and "" with this function in the post receiving script.
-------------------------------
function is_filled_out()
{
// test that each variabl has a value
foreach($_POST as $key => $value)
{
if(is_null($value) || $value="")
return false;
}
return true;
}
---------------------
but when I submit the form without putting any value, it returns 'true'.
what's wrong with my code?
