PHP必填字段错误

我正试着做一个必填字段。。它会发布所需的错误，但也会发布set_消息。set_消息应仅在成功时显示

但它同时发布了这两个消息。所发生的情况是，如果函数为空，则必填字段不会阻止函数更新

<?php 
function recover_password(){

    $errors = [];


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

        if (isset($_SESSION['token']) && $_POST['token'] === $_SESSION['token']) {

            $email = clean($_POST['email']);

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

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



            if (email_exists($email)) { 

                $validation_code = generaterandom(12);

                setcookie('temp_access_code', $validation_code, time() + 86400);

                $sql = "UPDATE users SET validation_code = '" . escape($validation_code) . "' WHERE user_email = '" . escape($email) . "'";
                $result = query($sql);


                set_message("Instructions to reset your password have been emailed to you");        


            } else {

                echo validation_errors("This email does not exist");
            }
        } else {

            redirect("index.php");
        }
    }
}
?>

这应该没问题。 你的如果。。。否则就没问题了。 但是语句$errors=[]；不是

这是完美的工作，我需要添加另一个else语句我已经更新了代码

function recover_password()
{
    $errors = [];

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

        if (isset($_SESSION['token']) && $_POST['token'] === $_SESSION['token']) {

            $email = clean($_POST['email']);

            if (empty($email)) {

                $errors[] = "Email Address Required";
            }

            if (! empty($errors)) {

                echo validation_errors($errors[0]);
            } else {

                if (email_exists($email)) {

                    $validation_code = generaterandom(12);

                    setcookie('temp_access_code', $validation_code, time() + 86400);

                    $sql = "UPDATE users SET validation_code = '" . escape($validation_code) . "' WHERE user_email = '" . escape($email) . "'";
                    $result = query($sql);


                    set_message("Instructions to reset your password have been emailed to you");
                } else {

                    echo validation_errors("This email does not exist");
                }
            }
        } else {

            redirect("index.php");
        }
    }
}

解析器遇到的else在哪里？您的第一个代码片段非常不完整。您正在使用HTML5吗？如果是这样，只需向输入中添加一个必需的属性。@JayBlanchard您仍然需要执行服务器端检查，因为客户端检查很容易被绕过。在健壮验证的基础上，将其用作一个很好的增强+

function recover_password()
{
    $errors = [];

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

        if (isset($_SESSION['token']) && $_POST['token'] === $_SESSION['token']) {

            $email = clean($_POST['email']);

            if (empty($email)) {

                $errors[] = "Email Address Required";
            }

            if (! empty($errors)) {

                echo validation_errors($errors[0]);
            } else {

                if (email_exists($email)) {

                    $validation_code = generaterandom(12);

                    setcookie('temp_access_code', $validation_code, time() + 86400);

                    $sql = "UPDATE users SET validation_code = '" . escape($validation_code) . "' WHERE user_email = '" . escape($email) . "'";
                    $result = query($sql);


                    set_message("Instructions to reset your password have been emailed to you");
                } else {

                    echo validation_errors("This email does not exist");
                }
            }
        } else {

            redirect("index.php");
        }
    }
}
