17 十三章 想函数传递表单数据

<?php
        // 这里提交的 _POST['name1'] 与 html中 name = name1 要一致

        function validataEmail($email)
        {
                $regexp = "^([_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.[a-z]{2,6})$";
                if(eregi($regexp,$email))return 1;
                else
                        return 0;
        }

        if(isset($_POST['submit']))
        {
                $name = htmlentities($_POST['name1']);
                $email = htmlentities($_POST['email1']);
                printf("hi %s ",$name);
                if(validataEmail($email))
                        printf("the address %s will soon be a spam-magnet ",$email);
                else
                        printf("bad email ");
        }
?>

<form action = "test7.php" method = "post">
        <p>
                Name:<br />
                <input type="text" id = "name" name = "name1" size = "20" maxlength = "40" />
        </p>
        <p>
                Email Address:<br />
                <input type = "text" id = "email" name = "email1" size = "20" maxlength = "40" />
        </p>
        <input type = "submit" id = "submit" name = "submit" value = "Go" />
</form>

//注意 name = "name 1"  与 POST中 配合
