Re: How do I validate input using php?

Here's the code I use to validate emails: function check_email($email) { global $email; $regex="^([a-z0-9_]|\\-|\\.)+@(([a-z0-9_]|\\-)+\\.)+[a-z]{2,4}$"; return eregi($regex, $email, $trash); } Hope this helps, Mike "ØYstein HåLand" <molen@mbox302.swipnet.se> wrote in message news:20020724224014.62119.qmail@pb1.pair.com... > I've tried a function like this: > function validate() { // > if ( is_numeric($input1) && is_numeric($input2) && ctype_alpha($input3) > && > ctype_alpha($input4) ) > return true; > } > > > And then I call the function: > > if (validate() == false) { > some action; > } > > My problem is I get the action every time, even though the input is of the > right type.
