Question

我正在使用php处理程序（signup-form-handler.php）创建一个注册表单（signup.html）。但似乎我做错了什么。

这是我的代码：

$errors = '';
$myemail = 'example@domain.com';//<-----Put Your email address here.
if(empty($_POST['FirstName'])  || 
   empty($_POST['LastName'])  || 
   empty($_POST['City'])  || 
   empty($_POST['Country']))
{
    $errors .= "\n Error: all fields are required";
}

$FirstName = $_POST['FirstName']; 
$LastName = $_POST['LastName'];
$City = $_POST['City'];
$Country = $_POST['Country'];
$Int1 = $_POST['Int1'];       // <---- Here's what seems to be the issue
$Int2 = $_POST['Int2'];       // <---- Here's what seems to be the issue 

if( empty($errors))
{
    $to = $myemail; 
    $email_subject = "Udfyldelse af test på Gamification: $FirstName";
    $email_body = "Du har fået en ny besvarelse. ".
    "Her er besvarelserne:\n Fornavn: $FirstName \n Efternavn: $LastName \n By: $City \n Land $Country \n".
    "De fire personlige interesser: $Int1 og $Int2"; 

    $headers = "From: $myemail\n"; 

    mail($to,$email_subject,$email_body,$headers);
    //redirect to the 'thank you' page
    header('Location: contact-form-thank-you.html');
}

以下是相关的HTML代码：

<form id="contact_form" name="contact_form" action="signup-form-handler.php">


    <!-- Personlige oplysninger -->
    <div class="next">

        <h3>Personlige oplysninger<a class="info" href="#" title="Testing"><img style="height: 15px; width: 15px; margin-left: 5px;" alt="Time" src="img/signup_form/info_simple.png"></a></h3>


        <b>Mit navn er</b>
        <input class="user_field" placeholder="fornavn" id="FirstName" name="FirstName" type="text" maxlength="60" />
        <input class="user_field" placeholder="efternavn" id="LastName" name="LastName" type="text" maxlength="60" />
        </br>


        <b>og bor i</b>
        <input class="user_field" placeholder="indsæt by" id="City" name="City" type="text" maxlength="60" />
        <b>,</b>
        <input class="user_field" placeholder="indsæt land" id="Country" name="Country" type="text" maxlength="60" />
        </br>

        </br>
        <b>Beskriv dig selv med 4 interesser</b>
        </br>
        <input id="Int1" name="Int1" class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 1" />
        <input id="Int2" name="Int2" class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 2" />
        <input class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 3" />
        <input class="tag_btn user_field" style="color: #FFFFFF;" placeholder="Interesser 4" />

    </div>

从我的代码示例中可以看出，我正在尝试从我的html表单中获取输入。我已经评论了问题发生的代码。如果我从Int1和Int2检索输入，我得到答案，需要填写所有必填字段，但我不想要求Int1和Int2。另外我没有在开头添加Int1和Int2，我检查其他变量是否为空。如果我删除Int1和Int2它一切正常。

当我在插入所有输入后发送表单时，我收到以下消息： “错误：所有字段都是必需的”

我做错了什么？

希望我提供足够的信息来找到问题，谢谢！

Answer 1

默认方法是GET。将表单方法设置为POST：

<form id="contact_form" name="contact_form" action="signup-form-handler.php" method="POST">

所以基本上你没有将值传递给脚本。如果您想使用GET方法，请将$ _POST的所有实例切换为$ _GET，您可以保留表单。

Answer 2

在输入Int1和Int2中，缺少属性类型。

Answer 3

好的，对于初学者来说，＆＃34;＆lt; b＆gt;＆＃34;对于粗体标签进行删除，使用＆＃34;＆lt;强大＆gt; ＆LT; / strong＆gt; ＆＃34;

如果你将它添加到你的php页面它可以工作，玩那个表格虽然因为我无法理解丹麦语知道什么是什么。这是一个单页解决方案，不需要HTML文件

<?php
$form = '<form id="contact_form" name="contact_form" action="'.$_SERVER['PHP_SELF'].'" method="post" >

所有字段都需要PHP错误 - 但插入了所有字段
