PHP 表单不会将价值传递给任何人？

Question

出于某种奇怪的原因，业务输入值不会提交到电子邮件...它总是空白..有人可以告诉我出了什么问题吗？谢谢！

<?php
// Check for empty fields
if(isset(empty($_POST['submit'])      ||
   empty($_POST['email'])     ||
   empty($_POST['phone'])     ||
   empty($_POST['business'])  ||
   empty($_POST['message'])   ||
   !filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
   {
   echo "No arguments Provided!";
   return false;
   }

$name = strip_tags(htmlspecialchars($_POST['name']));
$email_address = strip_tags(htmlspecialchars($_POST['email']));
$phone = strip_tags(htmlspecialchars($_POST['phone']));
$business = strip_tags(htmlspecialchars($_POST['business']));
$message = strip_tags(htmlspecialchars($_POST['message']));

// Create the email and send the message
$to = 'somekoreanguy@gmail.com'; // Add your email address inbetween the '' replacing yourname@yourdomain.com - This is where the form will send a message to.
$email_subject = "Website Contact Form:  $name";
$email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nEmail: $email_address\n\nPhone: $phone\n\nBusiness: $business\n\nMessage:\n$message";
$headers = "From: noreply@yourdomain.com\n"; // This is the email address the generated message will be from. We recommend using something like noreply@yourdomain.com.
$headers .= "Reply-To: $email_address";   
mail($to,$email_subject,$email_body,$headers);
return true;         
?>

这是我的 HTML：

<form name="sentMessage" id="contactForm" novalidate method="post">
                    <div class="row">
                        <div class="col-md-6">
                            <div class="form-group">
                                <input type="text" class="form-control" placeholder="Your Name *" id="name" required data-validation-required-message="Please enter your name.">
                                <p class="help-block text-danger"></p>
                            </div>
                            <div class="form-group">
                                <input type="email" class="form-control" placeholder="Your Email *" id="email" required data-validation-required-message="Please enter your email address.">
                                <p class="help-block text-danger"></p>
                            </div>
                            <div class="form-group">
                                <input type="tel" class="form-control" placeholder="Your Phone *" id="phone" required data-validation-required-message="Please enter your phone number.">
                                <p class="help-block text-danger"></p>
                            </div>
                            <div class="form-group">
                                <input type="text" class="form-control" placeholder="Your Business Name *" id="business" required data-validation-required-message="Please enter your business name.">
                                <p class="help-block text-danger"></p>
                            </div>
                            <div class="col-md-6">
                                <div class="form-group">
                                    <textarea class="form-control" placeholder="Your Message *" id="message" required data-validation-required-message="Please enter a message."></textarea>
                                    <p class="help-block text-danger"></p>
                                </div>
                            </div>
                        <div class="clearfix"></div>
                        <div class="col-lg-12 text-center">
                            <div id="success"></div>
                            <button type="submit" name="submit" class="btn btn-xl">Send Message</button>
                        </div>
                    </div>
                </form>

由于某种原因，当我输入“empty($_POST['business']) ||”在那里，电子邮件没有任何内容。当我从我的业务 html 部分中删除 "type="text" 时，电子邮件会通过，但没有任何价值。它只会说业务：和空白....

Answer 1

你没有定义method="post"

<form name="sentMessage" id="contactForm" novalidate>

所以它会像

<form name="sentMessage" id="contactForm" novalidate method="post">

给

起名字

<button type="submit" name ="submit" class="btn btn-xl">Send Message</button>

所以你的代码将是

if(isset($_POST['submit']){
//set your code here
}

Answer 2

它总是空白，因为在您的输入表单中没有name=""，name="" 在提交表单后引用表单数据。像这样将name="" 添加到您的输入中..

<?php
// Check for empty fields
if(isset($_POST['submit'])) {
if(trim($_POST['email'])== ''  || trim($_POST['phone'])== ''   || trim($_POST['business'])== ''  || trim($_POST['message'])== ''  || !filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
{
echo "No arguments Provided!";
}else{
$name = strip_tags(htmlspecialchars($_POST['name']));
$email_address = strip_tags(htmlspecialchars($_POST['email']));
$phone = strip_tags(htmlspecialchars($_POST['phone']));
$business = strip_tags(htmlspecialchars($_POST['business']));
$message = strip_tags(htmlspecialchars($_POST['message']));

// Create the email and send the message
$to = 'somekoreanguy@gmail.com'; // Add your email address inbetween the '' replacing yourname@yourdomain.com - This is where the form will send a message to.
$email_subject = "Website Contact Form:  $name";
$email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nEmail: $email_address\n\nPhone: $phone\n\nBusiness: $business\n\nMessage:\n$message";
$headers = "From: noreply@yourdomain.com\n"; // This is the email address the generated message will be from. We recommend using something like noreply@yourdomain.com.
$headers .= "Reply-To: $email_address";   
mail($to,$email_subject,$email_body,$headers);
}
}
?>
