Question

I am a new programmer and I tried a bunch of different ways to validate my code and clearly am doing it totally wrong. Any help would be appreciated. I am still working on validating just the name. This version clearly doesn’t make sense but i couldn’t get it to work any way I try.

  <?php

require_once ('includes/classes/database.php');
require_once('includes/classes/user.php');
require_once('includes/header.php');


// if user submits a new registration
if (isset($_POST['name'],$_POST['email'],$_POST['pwd'],$_POST['pwd2']))
{
    if(strlen(trim($_POST['name'])) <= 20)
    { 
        return (true);
        return $name;
    }
    else
    {
        return (false);
    }

    // validate input fields
    //$name = $_POST['name'];
    $email = $_POST['email'];
    $password = $_POST['pwd'];
    $password2 = $_POST['pwd2'];

    // if error fall through and redisplay page with errors

    // if no errors update database and redirect to homepage
    if ($uc->add_member($name, $email, $password) === FALSE)
    {
        echo "System Error. damn if I know what to do";
    } 
    else
    {
        header("location: homepage.php");
    }
}

?>

Answer 1

if (strlen(trim($_POST['name']))<=20)
{ 
    return (true);    }
else
{
    return (false);
}

Just get the return name out. Then it will work.
