Question

我一直在解决一个问题，因为有很多字段的表单没有通过PHP邮件表单正确填充。

我回到基础，将其分解为几个字段，当第二组复选框数据添加到混合中时，我似乎遇到了问题。如下所示，电子邮件将发送，并且正文包含所有内容，包括$ sport_msg。它不包括$ availability_msg或$ message，尽管它是在我添加第二组复选框数据之前这样做的。

我90％肯定问题出在$ email_body的语法上，但我不确定我的错误。或者它可能与我在两组复选框中的'foreach'片段周围的括号有关。有人能比PHP更好的给我另一套眼睛吗？

我的PHP：

<?php
if(!isset($_POST['submit']))
{
    //This page should not be accessed directly. Need to submit the form.
    echo "error; you need to submit the form!";
}
$name = $_POST['name'];
$company = $_POST['company'];
$visitor_email = $_POST['email'];
$sport = $_POST['sport'];
$message = $_POST['message'];

foreach($_POST['availability'] as $value) {
$availability_msg .= "$value\n";
}

foreach($_POST['sport'] as $value) {
$sport_msg .= "$value\n";
}



//Validate first
if(empty($name)||empty($visitor_email)) 
{
    echo "Name and email are mandatory!";
    exit;
}

if(IsInjected($visitor_email))
{
    echo "Bad email value!";
    exit;
}

$email_from = 'VGFV Guide Signup';//<== Shows up in the "from" field
$email_subject = "New Guide Signup";//<==  Email Subject

//Begin Email Body - I BELIEVE THIS IS WHERE MY ISSUE IS!!!

$email_body = "$name. has signed up from $company\n\n".
    "Here is the info:\n \n".
    "Guide Services Offered: \n".$sport_msg;
    "Availability: \n".$availability_msg;
    "$message \n \n".

$to = "myemailaddress@mydomain.com";//<== update the email address
$headers = "From: $email_from \r\n";
$headers .= "Reply-To: $visitor_email \r\n";
//Send the email!
mail($to,$email_subject,$email_body,$headers);
//done. redirect to thank-you page.
header('Location: thank-you.html');


// Function to validate against any email injection attempts
function IsInjected($str)
{
  $injections = array('(\n+)',
              '(\r+)',
              '(\t+)',
              '(%0A+)',
              '(%0D+)',
              '(%08+)',
              '(%09+)'
              );
  $inject = join('|', $injections);
  $inject = "/$inject/i";
  if(preg_match($inject,$str))
    {
    return true;
  }
  else
    {
    return false;
  }
}

?>

Answer 1

声明变量，因为如果数组为空，则循环不会设置它们：

$availability_msg = '';
$sport_msg = '';

$email_body中也存在语法错误，这是修复后的版本：

$email_body = "$name. has signed up from $company\n\n".
    "Here is the info:\n \n".
    "Guide Services Offered: \n".$sport_msg .
    "Availability: \n".$availability_msg .
    $message;

Answer 2

您是否检查过这些值，例如

error_log(print_r($_POST,1));
error_log(print_r($_POST['availability'],1);
error_log(print_r($_POST['sport'] ,1));

您是否事先检查了传递给邮件功能的变量，例如（对所有这些变量执行此操作）：

error_log(" TO>".$to."<");

此外，邮件功能的返回值是什么？

第二组复选框表格数据没有填充到PHP表单邮件正文中？
