PHP 必填字段错误 - PHP Required field Error

PHP Required field Error

本文关键字：错误字段 PHP | 更新日期: 2023-09-27

我正在尝试使字段成为必填字段..它发布了所需的错误，但它也发布了set_message应该仅在成功时显示set_message。

但它同时发布两者。正在发生的事情是必填字段不会阻止函数更新，如果其为空

<?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。您的如果...否则构造似乎还可以。但是语句 $errors = []; 不是

<?php 
function recover_password(){
    $errors = array();
    if ($_SERVER['REQUEST_METHOD'] == "POST") {
        if (isset($_SESSION['token']) && $_POST['token'] === $_SESSION['token']) {
            $email = clean($_POST['email']);
            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");
        }
    }
}
?>

这非常有效，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");
        }
    }
}
