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?
It is my understanding (not sure if it is correct though) that if your form has a field named x and the user does not enter any value in that field, there will be no entry for field x in the $_POST array. so your loop should never return false. To see if they entered a value in field X you need to code something like this
if(! $_POST['x']){
do what ever you do when they don't fill out a required field;
