Question

我有这个表单页面：http://webauthorsgroup.com/raa/contacform/index3.html产生“空字段”错误，但我无法确定这个错误发生的位置。

我使用以下php表单：

<?php
if($_POST)
{
    $to_Email       = "email@email.com"; //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);
    $user_Last       = filter_var($_POST["userLast"], FILTER_SANITIZE_STRING);

您与某些变量命名不一致。查看HTML源代码，您有以下变量：

    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

查看代码，您正在寻找没有下划线的变量：

这里：

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

另外：让user_First和userFirst都很混乱，您可能希望将其清理干净以备将来调试。
