$school_name = (!empty($_POST['school_name'])) ? $_POST['school_name'] : NULL;
$school_name = FilterALLHTML($school_name);
Is there a way to combine the to above into 1 line?
Imagine I have 50 varibales assigned by this method on a page
$school_name = (!empty($_POST['school_name'])) ? $_POST['school_name'] : NULL;
Now to run FilterALLHTML function on them I would have to add another 50 lines
