带有错误消息的 PHP Contactform 不会触发 php 脚本

Question

我为一个带有一些错误消息的简单联系表单制作了一个 index.php。 脚本和表单在同一个 index.php 中（也试过外部，没有工作）现在我想知道为什么这个脚本不工作我没有收到邮件，我没有收到错误消息，也没有从服务器端收到正确的错误我检查了几次，如果我在变量中犯了一些错误，但我找不到任何人。 希望在这里得到帮助，知道为什么它不起作用吗？ 也许 PHP 脚本没有被激活（它在 index.php 文件中的实际表单之前）

首先尝试stackoverflow :)

这是PHP脚本

if (isset($_POST['submit'])) {
$name = $_POST['name'];
$prename = $_POST['prename'];
$sex = $_POST['sex'];
$company = $_POST['company'];
$email = $_POST['email'];
$mobile = $_POST['mobile'];
$message = $_POST['message'];
$from = 'Demo Contact Form';
$to = 'martin.niklaus@gmx.com';
$subject = 'Message from Contact form';

$body = 'From: $sex $prename $name\n Company: $company\n  E-Mail: $email\n Mobile: $mobile\n Message:\n $message';

// Check if name has been entered
if (!$_POST['name']) {
    $errName = 'Please enter your name';
}

// Check if prename has been entered
if (!$_POST['prename']) {
    $errPrename = 'Please enter your prename';
}

// Check if sex has been entered
if (!$_POST['sex']) {
    $errSex = 'Please choose your sex';
}

// Check if Companyname has been entered
if (!$_POST['company']) {
    $errCompany = 'Please enter your Companis name';
}


// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
    $errEmail = 'Please enter a valid email address';
}

// Check if mobilenumber has been entered
if (!$_POST['mobile']) {
    $errMobile = 'Please enter your mobilenumber';
}

// Check if prename has been entered
if (!$_POST['prename']) {
    $errPrename = 'Please enter your prename';
}

//Check if message has been entered
if (!$_POST['message']) {
    $errMessage = 'Please enter your message';
}

// If there are no errors, send the email
if (!$errName && !$errPrename && !$errSex && !$errCompany && !$errEmail && !$errMessage && !$errMobile) {
    if (mail($to, $subject, $body, $from)) {
        $result = '<div class="alert alert-success">Thank You! I will be in touch</div>';
    } else {
        $result = '<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
    }
}
}

和HTML脚本

<div class="form-holder mg-bottom-50">
              <form accept-charset="UTF-8" action="index.php" method="post">
                 <div class="col-md-6">

                    <input id="name" name="name" type="text" value="<?php echo htmlspecialchars($_POST['name']); ?>"/>
        <?php echo "<p class='text-danger'>$errName</p>";?>

Answer 1

问题：电子邮件格式错误，但消息不会显示 bcaz

<?php echo "<p class='text-danger'>$errName</p>";?>

代替

<?php echo "<p class='text-danger'>$errEmail</p>";?>

修改后的脚本如下

php

<?php
if (isset($_POST['name'])) {

$name    = $_POST['name'];
$prename = $_POST['prename'];
$sex     = $_POST['sex'];
$company = $_POST['company'];
$email   = $_POST['email'];
$mobile  = $_POST['mobile'];
$message = $_POST['message'];
$from    = 'Demo Contact Form';
$to      = 'martin.niklaus@gmx.com';
$subject = 'Message from Contact form';

$body = 'From: $sex $prename $name\n Company: $company\n  E-Mail: $email\n Mobile: $mobile\n Message:\n $message';

// Check if name has been entered
if (!$_POST['name']) {
    $errName = 'Please enter your name';
}

// Check if prename has been entered
if (!$_POST['prename']) {
    $errPrename = 'Please enter your prename';
}

// Check if sex has been entered
if (!$_POST['sex']) {
    $errSex = 'Please choose your sex';
}

// Check if Companyname has been entered
if (!$_POST['company']) {
    $errCompany = 'Please enter your Companis name';
}

// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
    $errEmail = 'Please enter a valid email address';
}

// Check if mobilenumber has been entered
if (!$_POST['mobile']) {
    $errMobile = 'Please enter your mobilenumber';
}

//Check if message has been entered
if (!$_POST['message']) {
    $errMessage = 'Please enter your message';
}

// If there are no errors, send the email
if (!isset($errName) && !isset($errPrename) && !isset($errSex) && !isset($errCompany) && !isset($errEmail) && !isset($errMessage) && !isset($errMobile)) {

    if (mail($to, $subject, $body, $from)) {
        $result = '<div class="alert alert-success">Thank You! I will be in touch</div>';
    } else {
        $result = '<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
    }
}

}
?>

小笔记

您需要改进错误显示部分并在输入中检索 POST 变量。
