Ajax/PHP 联系表单空白字段 - Ajax/PHP contact form blank fields

您好，我已经在我的网站上制作了一个联系表格，但是当用户输入详细信息并提交表格时，它会发送一些空白信息，找不到原因。此外，一个主要问题是，表单更改了国家/地区的名称字段，因此它看起来像"名称：法国"而不是"名称：约翰"。

我还从这里添加了表单验证器 https://github.com/1000hz/bootstrap-validator。有人知道为什么会这样吗？下面是js，php和html。

$("#contactForm").validator().on("submit", function (event) {
    if (event.isDefaultPrevented()) {
        // handle the invalid form...
        formError();
        submitMSG(false, "Something went wrong! Did you fill in the form properly?");
    } else {
        // everything looks good!
        event.preventDefault();
        submitForm();
    }
});
function submitForm(){
    // Initiate Variables With Form Content
    var name = $("#name").val();
	var last = $("#last").val();
    var email = $("#email").val();
	var company = $("#company").val();
	var users = $("#users").val();
	var country = $("#country").val();
    var msg_subject = $("#msg_subject").val();
    var message = $("#message").val();
    $.ajax({
        type: "POST",
        url: "assets/php/form-process.php",
        data: "name=" + name + "&last=" + last + "&email=" + email + "&company=" + company + "&users=" + users + "&country=" + country + "&msg_subject=" + msg_subject + "&message=" + message,
        success : function(text){
            if (text == "success"){
                formSuccess();
            } else {
                formError();
                submitMSG(false,text);
            }
        }
    });
}
function formSuccess(){
    $("#contactForm")[0].reset();
    submitMSG(true, "Message Submitted!")
}
function formError(){
    $("#contactForm").removeClass().addClass('shake animated').one('webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend', function(){
        $(this).removeClass();
    });
}
function submitMSG(valid, msg){
    if(valid){
        var msgClasses = "h3 text-center tada animated text-success";
    } else {
        var msgClasses = "h3 text-center text-danger";
    }
    $("#msgSubmit").removeClass().addClass(msgClasses).text(msg);
}

任何帮助将不胜感激:)

你的问题之一是变量归因，每个输入都应该有自己的变量

你做

$name = $_POST["name"];
...
$name = $_POST["last"];
...
$name = $_POST["company"];
...
$name = $_POST["users"];
...
$name = $_POST["country"];

你应该有

$name = $_POST["name"];
...
$last = $_POST["last"];
...
$company = $_POST["company"];
...
$users = $_POST["users"];
...
$country = $_POST["country"];

最后一个属性是国家，这就是为什么你有

名称：
法国"而不是"名称：约翰"
