Question

我的网站有一个基本的4字段PHP表单。我已将其设置为通过姓名，电子邮件，电话和消息的形式向我发送电子邮件。这部分有效。不起作用的是，当人们没有填写任何内容时，没有错误信息。相关，当提交按钮成功向我的电子邮件发送消息时，没有成功消息。请提前告知并谢谢你！

这是我的表单和PHP

的index.php

<form class="form-horizontal" role="form" method="post" action="processes.php">
<div class="form-group">
    <label for="name" class="col-sm-2 control-label">Name</label>
    <div class="col-sm-10">
        <input type="text" class="form-control" id="name" name="name" placeholder="First &amp; Last Name" value="">
    </div>
</div>
<div class="form-group">
    <label for="email" class="col-sm-2 control-label">Email</label>
    <div class="col-sm-10">
        <input type="email" class="form-control" id="email" name="email" placeholder="Shoot me an email!" value="">
        <?php echo "<p class='text-danger'>$errEmail</p>";?>
    </div>
</div>
<div class="form-group">
    <label for="phone" class="col-sm-2 control-label">Phone</label>
    <div class="col-sm-10">
        <input type="phone" class="form-control" id="phone" name="phone" placeholder="Let's talk!" value="">
    </div>
</div>
<div class="form-group">
    <label for="message" class="col-sm-2 control-label">Message</label>
    <div class="col-sm-10">
        <textarea class="form-control" rows="4" name="message"></textarea>
        <?php echo "<p class='text-danger'>$errMessage</p>";?>
    </div>
</div>
<div class="form-group">
    <div class="col-sm-10 col-sm-offset-2">
        <input id="submit" name="submit" type="submit" value="Send" class="btn btn-default">
    </div>
</div>
<div class="form-group">
    <div class="col-sm-10 col-sm-offset-2">
        <! Will be used to display an alert to the user>
    </div>
</div>
</form>

来自processes.php

<?php
    if (isset($_POST["submit"])) {
        $name = $_POST['name'];
        $email = $_POST['email'];
        $phone = $_POST['phone'];
        $message = $_POST['message'];
        $from = 'Contact Form'; 
        $to = 'mybusiness@gmail.com'; 
        $subject = 'Contact Form';

        $body = "From: $name\n E-Mail: $email\n Phone: $phone\n Message:\n $message";


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

// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage) {
    if (mail ($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>';
    }
}
    }
?>

尝试这一点，它一直对我有用！ :)

首先创建一个错误输出函数：

function error_output($errors){
    return '<ol><li>' . implode('</li><li>', $errors) . '</li></ol>';
}

然后，在代码内部使用errors[] =来设置错误。

这样的事情：

if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
    $errors[] = 'Please enter a valid email address';
}

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

如果errors变量不为空，请将它们输出到页面：

if(!empty($errors)){
    echo error_output($errors);
} else {
    //execute code
}

它应该使您的代码更清晰，更容易输出错误！

希望这有帮助！
