Question

下面显示了我的HTML文件的摘录。表单目标是当用户选择一个复选框时，它会在起始总值上添加另一个值。

<!doctype html>  

 <html  class="">  
  <head>

  <script type="text/javascript">
    function checkTotal() {
        document.listForm.total.value = '';
        var sum = 68.50;
        for (i=0;i<document.listForm.choice.length;i++) {
          if (document.listForm.choice[i].checked) {
            sum = sum + parseFloat(document.listForm.choice[i].value);
          }
        }
        document.listForm.total.value = sum.toFixed(2);
    }
</script>

  </head>

  <body>


   <form name="listForm" method="post" action="standard_form.php">

  <div class="form-group">
   <label for="additional_extras">Extras</label><br><br>
<input type="checkbox" name="choice" value="60.00" onchange="checkTotal()"> Number1 </div>

  <div class="form-group">
   <label for="additional_extras_2"></label><br>
<input type="checkbox" name="choice" value="20.00" onchange="checkTotal()"> Number 2
</div>

 <div class="form-group">
   <label for="additional_extras_3"></label><br>
<input type="checkbox" name="choice" value="45.00" onchange="checkTotal()"> Number 3
</div>

 <div class="form-group">
   <label for="additional_extras_4"></label><br>
<input type="checkbox" name="choice" value="23.50" onchange="checkTotal()"> Number 4
</div>

<div class="form-group">
   <label for="additional_extras_5"></label><br>
<input type="checkbox" name="choice" value="40.00" onchange="checkTotal()"> Number 5
</div>

<div class="form-group">
   <label for="additional_extras_6"></label><br>
<input type="checkbox" name="choice" value="23.50" onchange="checkTotal()"> Number 6
</div>

<div class="form-group">
   <label for="additional_extras_7"></label><br>
<input type="checkbox" name="choice" value="120.00" onchange="checkTotal()"> Number 7

<br>
  <h3>Your Current Package Total: £<input type="text" readonly placeholder="68.50"  name="total" id="total"/></h3>

  <button type="submit" class="btn btn-default">Submit</button>  

</form>   

     </div>

  </body>
</html>

然后我会将此表单发送到以下php文件，然后通过电子邮件发送表单输出。我已设法成功发送所有其他字段但无法获取复选框值以通过电子邮件发送，而无需添加功能（这使得总计）中断。

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

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "myemail";
    $email_subject = "mysubject";

    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();
    }

        $choice = $_POST['choice']; // required
        $total = $_POST['total']; // required

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

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }

    $email_message .= "Choice: ".clean_string($choice)."\n";
    $email_message .= "Order Total: ".clean_string($total)."\n";


// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>

<!-- include your own success html here -->

Thank you for contacting us. We will be in touch with you very soon.

<?php
}
?>

请有人为此解决问题吗？我尝试过什么，我只是不能通过复选框发送值，并在电子邮件中显示自己，如表格的其余部分。

非常感谢任何帮助！

谢谢！

  <div class="form-group">
   <label for="additional_extras">Extras</label><br><br>
<input type="checkbox" name="choice[]" value="60.00" onchange="checkTotal()"> Number1 </div>

  <div class="form-group">
   <label for="additional_extras_2"></label><br>
<input type="checkbox" name="choice[]" value="20.00" onchange="checkTotal()"> Number 2
</div>

 <div class="form-group">
   <label for="additional_extras_3"></label><br>
<input type="checkbox" name="choice[]" value="45.00" onchange="checkTotal()"> Number 3
</div>

 <div class="form-group">
   <label for="additional_extras_4"></label><br>
<input type="checkbox" name="choice[]" value="23.50" onchange="checkTotal()"> Number 4
</div>

<div class="form-group">
   <label for="additional_extras_5"></label><br>
<input type="checkbox" name="choice[]" value="40.00" onchange="checkTotal()"> Number 5
</div>

<div class="form-group">
   <label for="additional_extras_6"></label><br>
<input type="checkbox" name="choice[]" value="23.50" onchange="checkTotal()"> Number 6
</div>

<div class="form-group">
   <label for="additional_extras_7"></label><br>
<input type="checkbox" name="choice[]" value="120.00" onchange="checkTotal()"> Number 7

将复选框的名称更改为选项[]，以便将其用作数组。

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

foreach($choice as $c){
   $emailbody .= 'Checkbox .'$c;
}

当您提交表单时，它会像这样：

array(1) { ["choice"]=> array(5) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(1) "3" [3]=> string(1) "4" [4]=> string(1) "5" } }

所以，你可以像$ _POST ['choice'] [0]或[1]或[2]那样进行操作。

Answer 2

您正在使用SAME名称构建所有复选框输入。这意味着PHP将处理表单提交并不断覆盖特定字段名称的“先前”版本：带有新副本的值对，例如

<input type="text" name="foo" value="foo" />
<input type="text" name="foo" value="bar" />
<input type="text" name="foo" value="baz" />

（注意同名，3个不同的值）。只有baz会显示在$ _POST / $ _ GET中，因为它是表单中foo名称的最后一个副本。

如果您希望提交和保存各个复选框值，则必须在字段命名中使用特定于PHP的数组表示法：

<input type="text" name="foo[]" value="foo" />
<input type="text" name="foo[]" value="bar" />
<input type="text" name="foo[]" value="baz" />
                            ^^--note the [] brackets

这会将$_POST['foo']转换为数组，并告诉PHP将每个值保存为数组元素。
