What is the best way of checking whether or not a form has been submitted to determine whether I should pass the form’s variables to my validation class?
First I thought maybe:
But that will always return true as a superglobal is defined everywhere. I don’t want to have to iterate through each element of my form with:
if(isset($_POST['element1']) || isset($_POST['element2']) || isset(...etc
Whilst writing this question I thought of a much more basic solution, add a hidden field to act as a flag that I can check.
Is there a ‘cleaner’ way to do it than adding my own flag?
For general check if there was a
POST action use:
EDIT: As stated in the comments, this method won’t work for in some cases (e.g. with check boxes and button without a name). You really should use:
if ($_SERVER['REQUEST_METHOD'] == 'POST')
