單頁腳本錯誤

我有這種形式的頁面：http://webauthorsgroup.com/raa/contacform/index3.html它正在產生一個「空字段」的錯誤，但我無法確定這個錯誤發生的位置。單頁腳本錯誤

我使用下面的PHP形式：

<?php 
if($_POST) 
{ 
    $to_Email  = "[email protected]"; //Replace with recipient email address 
    $subject  = 'Web Form'; //Subject line for emails 

    //check if its an ajax request, exit if not 
    if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') { 

     //exit script outputting json data 
     $output = json_encode(
     array(
      'type'=>'error', 
      'text' => 'Request must come from Ajax' 
     )); 

     die($output); 
    } 

    //check $_POST vars are set, exit if any missing 
    if(empty($_POST["userFirst"]) || empty($_POST["userLast"]) || empty($_POST["userPhone"]) || empty($_POST["userEmail"])) 
    { 
     $output = json_encode(array('type'=>'error', 'text' => 'Input fields are empty!')); 
     die($output); 
    } 

    //Sanitize input data using PHP filter_var(). 
    $user_First  = filter_var($_POST["userFirst"], FILTER_SANITIZE_STRING);

你是不是您的一些變量命名的一致性。看你的HTML源代碼你有這些變量：

var user_First  = $('input[name=First]').val(); 
    var user_Last  = $('input[name=Last]').val(); 
    var user_Company  = $('input[name=Company]').val(); 
    var user_Address  = $('input[name=Address]').val(); 
    var user_City  = $('input[name=City]').val(); 
    var user_State  = $('input[name=State]').val(); 
    var user_Zip  = $('input[name=Zip]').val(); 
    var user_Phone

看你的代碼，你正在尋找變量沒有下劃線：

這裏：

$user_Company  = filter_var($_POST["userCompany"], FILTER_SANITIZE_EMAIL);

另外：兼具user_First和userFirst很混亂，你可能想清理它以備將來調試。
