Fadion Posted August 11, 2007 Share Posted August 11, 2007 Validation can involve lots of stuff, starting from empty fields, nr of characters, type of characters etc. Im just giving some points then im sure ull continue by yourself. empty fields: if($_POST['username'] == ""){ echo "Please fill the username field"; } nr of characters if(strlen($_POST['password']) > 6 or strlen($_POST['password']) < 3){ echo "The length of the password is incorrect"; } type of characters if(!is_numeric($_POST['phonenumber'])){ echo "The phone number is invalid"; } also u can use advanced methods to validate fields that have a specified format, like e-mail. Use regex in these cases: if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $_POST['email'])) { echo "The e-mail is invalid"; //i suck at regex so i just copy pasted that regex (also use preg instead of eregi) } Thats the basic idea of validation, which can be extended to a lot more. Just know what fields must be validated and how. Link to comment https://forums.phpfreaks.com/topic/64384-solved-validation-of-form/#findComment-321085 Share on other sites More sharing options...
