Question

我使用bootstrap ..我需要一次显示1个错误。以下代码将错误发布在不同的行中，并占用整个页面。

如果第一个字段中存在问题，则只能在继续下一个字段之前发布该错误，而不是一次发布所有字段。

function validate_registration(){
    $errors = [];    

    if ($_SERVER['REQUEST_METHOD'] == "POST") {


        $email = clean($_POST['email']);        
        $user_name = clean($_POST['user_name']);
        $birthdate = clean($_POST['birthdate']);
        $country = clean($_POST['country']);
        $password = clean($_POST['password']);
        $confirm_password = clean($_POST['confirm_password']);


        if (empty($email)) {
            $errors[] = "Email Address Required.";
        }
        if (email_exists($email)) {
            $errors[] = "Email Address in use.";
        }

        if (empty($user_name)) {
            $errors[] = "Username Required.";
        }
        if (strlen($user_name) < $min) {
            $errors[] = "Username is to short.";
        }

        if (user_exists($user_name)) {
            $errors[] = "Username Taken.";
        }

        if (empty($birthdate)) {
            $errors[] = "Birthdate Required.";
        }

        if (empty($country)) {
            $errors[] = "Country Required.";
        }

        if (empty($password)) {
            $errors[] = "Password Required.";
        }

        if ($password !== $confirm_password) {            
            $errors[] = "Your password fields do not match";
        }

        if (! empty($errors)) {            
            foreach ($errors as $error) {                
                echo validation_errors($error);
            }
        } else {

            if (register_user($email, $user_name, $birthdate, $country, $password)) {

             set_message('<div class="alert alert-success alert-dismissible" role="alert">
             <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
             Please check your email for account Information.</div>');

             redirect("../account/login.php");

            }
        }
    }
}

<强>更新：

根据您的意见，如果您想一次打印一个错误，而不是需要使用ELSEIF而不是IF：

filtered.length

Answer 2

您也可以通过保留现有代码来执行相同操作。

只需替换此代码： -

     if (!empty($errors)) {              
        echo validation_errors($errors[0]);               
     }

您也可以通过if else if方式获得相同的功能。将$ error声明为字符串。

$error = ''; 

if(empty($email)) {
            $error = "Email Address Required.";
        }
        else if (email_exists($email)) {
            $error = "Email Address in use.";
        }

        else if (empty($user_name)) {
            $error = "Username Required.";
        }
        else if (strlen($user_name) < $min) {
            $error = "Username is to short.";
        }

        else if (user_exists($user_name)) {
            $error = "Username Taken.";
        }

        else if (empty($birthdate)) {
            $error = "Birthdate Required.";
        }

        else if (empty($country)) {
            $error = "Country Required.";
        }

        else if (empty($password)) {
            $error = "Password Required.";
        }

        else if ($password !== $confirm_password) {            
            $error = "Your password fields do not match";
        }

       if (!empty($error)) { 

                echo validation_errors($error);

        } else {

            if (register_user($email, $user_name, $birthdate, $country, $password)) {

             set_message('<div class="alert alert-success alert-dismissible" role="alert">
             <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
             Please check your email for account Information.</div>');

             redirect("../account/login.php");

            }
        }

为什么不使用jquery验证进行客户端验证

然后使用服务器端验证，但显示为全部循环中的错误而不是内联。

因为客户端和服务器端验证很有用

验证时显示错误
