联系表格PHP脚本无法加载？

Question

因此，我正在尝试使用html和php脚本建立联系表单。 我过去已经做到了这一点（使用模板），但看起来都不错，但是我尝试自己创建一个，由于某些原因，它在html页面上提交脚本时并没有加载脚本（表单操作等都是正确的）。它必须与php有关，请参见下面的代码。 任何帮助将是巨大的：

   <?php

if(isset($_POST['email'])) {



    // EDIT THE 2 LINES BELOW AS REQUIRED

    $email_to = "text@email.co.uk";

    $email_subject = "Test form";





    function died($error) {

        // your error code can go here

        echo "We are very sorry, but there were error(s) found with the form you submitted. ";

        echo "These errors appear below.<br /><br />";

        echo $error."<br /><br />";

        echo "Please go back and fix these errors.<br /><br />";

        die();

    }



    // validation expected data exists

    if(!isset($_POST['teamname']) ||

        !isset($_POST['yourname']) ||

        !isset($_POST['secondname']) ||

        !isset($_POST['address']) ||

        !isset($_POST['postcode']) ||

        !isset($_POST['youremail']) ||

        !isset($_POST['phone']) ||

        !isset($_POST['otherplayername1']) ||

        !isset($_POST['otherplayername2']) ||

        !isset($_POST['otherplayername3']) ||

        !isset($_POST['otherplayername4']) ||

        !isset($_POST['otherplayername5']) ||

        !isset($_POST['otherplayername6']) ||

        !isset($_POST['otherplayername7']) ||

        !isset($_POST['location']) ||

 {

        died('We are sorry, but there appears to be a problem with the form you submitted.');       

    }



    $teamname = $_POST['teamname']; // required

    $yourname = $_POST['yourname']; // required

    $secondname = $_POST['secondname']; // not required

    $address = $_POST['address']; // not required

    $postcode = $_POST['postcode']; // required

    $your-email = $_POST['youremail']; // required

    $phone = $_POST['phone']; // not required


    $error_message = "";

    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';

  if(!preg_match($email_exp,$youremail)) {

    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';

  }

    $string_exp = "/^[A-Za-z .'-]+$/";

  if(!preg_match($string_exp,$yourname)) {

    $error_message .= 'The First Name you entered does not appear to be valid.<br />';

  }

  if(!preg_match($string_exp,$teamname)) {

    $error_message .= 'The Team Name you entered does not appear to be valid.<br />';

  }

   if(!preg_match($string_exp,$postcode)) {

    $error_message .= 'The Post Code you entered does not appear to be valid.<br />';

  }

  if(strlen($error_message) > 0) {

    died($error_message);

  }

    $email_message = "Form details below.\n\n";



    function clean_string($string) {

      $bad = array("content-type","bcc:","to:","cc:","href");

      return str_replace($bad,"",$string);

    }


    $email_message .= "First Name: ".clean_string($teamname)."\n";

    $email_message .= "First Name: ".clean_string($yourname)."\n";

    $email_message .= "Last Name: ".clean_string($secondname)."\n";

    $email_message .= "phone: ".clean_string($phone)."\n";

    $email_message .= "other player 1: ".clean_string($otherplayername1)."\n";

    $email_message .= "other player 2: ".clean_string($otherplayername2)."\n";

    $email_message .= "other player 3: ".clean_string($otherplayername3)."\n";

    $email_message .= "other player 4: ".clean_string($otherplayername4)."\n";

    $email_message .= "other player 5: ".clean_string($otherplayername5)."\n";

    $email_message .= "other player 6: ".clean_string($otherplayername6)."\n";

    $email_message .= "other player 7: ".clean_string($otherplayername7)."\n";



// create email headers

$headers = 'From: '.$email_from."\r\n".

'Reply-To: '.$email_from."\r\n" .

'X-Mailer: PHP/' . phpversion();

@mail($email_to, $email_subject, $email_message, $headers);

编辑：更新PHP和添加html

这也是我的HTML表单：

 <form name="contactform" method="post" action="contact.php">

<input type="text" name="teamname" value="" size="40" placeholder="Team Name"/><br>
<input type="text" name="yourname" value="" size="40" placeholder="Your Name"/><br>
<input type="text" name="secondname" value="" size="40" placeholder="Last Name"/><br>
<input type="text" name="address" value="" size="40" placeholder="Address"/><br>
<input type="text" name="postcode" value="" size="40" placeholder="Postcode"/><br>
<input type="email" name="youremail" value="" size="40" placeholder="Email"/><br>
<input type="tel" name="phone" value="" size="40" placeholder="Phone Number"/><br>
</div>

<input type="text" name="otherplayername1" value="" size="40" placeholder="Other Players Name 1"/><br>
<input type="text" name="otherplayername2" value="" size="40" placeholder="Other Players Name 2"/><br>
<input type="text" name="otherplayername3" value="" size="40" placeholder="Other Players Name 3"/><br>
<input type="text" name="otherplayername4" value="" size="40" placeholder="Other Players Name 4"/><br>
<input type="text" name="otherplayername5" value="" size="40" placeholder="Other Players Name 5"/><br>
<input type="text" name="otherplayername6" value="" size="40" placeholder="Other Players Name 6"/><br>
<input type="text" name="otherplayername7" value="" size="40" placeholder="Other Players Name 7"/><br>
<input type="text" name="location" value="" size="40"  placeholder="Location"/></span><br><br>
<input type="checkbox" /> <a target="_blank" style="color: #fff;">I confirm that I accept the Cash Leagues Rules and Regulations.</a>
<input type="submit" value="Send" action="contact.php"/></form>

Answer 1

$team-name = $_POST['team-name']; // required
$your-name = $_POST['your-name']; // required
$second-name = $_POST['second-name']; // not required
$your-email = $_POST['your-email']; // required

请勿在变量名中使用“-”：

$team-name -> $teamname
$your-name -> $yourname
...

并打开error_reporting，在进行开发以查看所有erros php都给您时:)（在这种情况下：解析错误）

第二个问题：您检查$_POST['email'] ，如果已设置，如果没有设置，则什么也不做。 但是在您的表单中，没有使用该名称的输入字段，因此您的脚本永远不会做任何事情。

Answer 2

变量名称中不允许使用字符- 。 尝试替换像

$team-name = $_POST['team-name']; // required

同

$team_name = $_POST['team-name']; // required

在PHP中，有效的变量名称以字母或下划线开头，后跟任意数量的字母，数字或下划线。 否-允许使用字符。 这是因为，否则数学运算符-会产生歧义。

您可以在官方文档页面中找到详细的说明。

无论如何，总的来说，我强烈建议您仔细阅读PHP产生的错误消息（并在寻求StackOverflow帮助时将其与源代码一起报告）：PHP，就像几乎所有的编程语言一样，在发生故障时非常有用。 如果你读了错误信息，则很可能是它告诉你问题是什么 ， 在哪里 ，已经发现（也就是通常，行号）。 例如，典型的PHP错误消息可能是

Fatal error: Call to undefined function my_function()
in /home/mysite/public_html/test.php on line 2 

其中Call to undefined function my_function()是问题，而/home/mysite/public_html/test.php加上line 2为您提供有关问题位置的信息。

如果您的脚本没有为您提供足够的信息，请参考手册中的“ 错误报告”页面：其中包含有关如何改进错误消息中的详细信息的宝贵信息。
