Hey,
Im trying to use preg_match to validate numbers in multiple fields. I can check one field but Im having trouble checking multiple fields.
preg_match ( '(foo)' , $_POST["num1"] ); <- That works fine. but I need to check multiple fields.
I thought I would build an array with the POST data like this...
$num = array ($_POST["num1"],
($_POST["num2"]); There are more than that...
and then use preg_match ('(foo)', $num) ; $num should point to my array, but that doesnt work. I get a warning message.. and it doesnt check the first num1 in the array.
Im certain that Its my code, and I wanted to get some input on what Im doing wrong.
