在Laravel控制器中从AJAX post请求向MySQL添加数据

标签: javascript php ajax laravel

我知道很多人都是通过jQuery解决这个问题,但我对此并不熟悉。

问题是我尝试使用html中的表单将数据发送到MySQL,使用javascript检索此数据,使用ajax将它们发送到php然后我尝试使用我的控制器“保存”它们。我收到了这个错误:

  

SQLSTATE [23000]:完整性约束违规:1048列'first_name'不能为空

我的ajax.js的代码是:

function ajaxSaveAddClient() {
var first_name = document.getElementById("first_name").value;
var last_name = document.getElementById("last_name").value;
var phone = document.getElementById("phone").value;
var cellphone = document.getElementById("cellphone").value;
var email = document.getElementById("email").value;
var city = document.getElementById("city").value;
var stock = document.getElementById("stock").value;
var source = document.getElementById("source").value;

var newClient = new Array();
newClient["first_name"] = first_name;
newClient["last_name"] = last_name;
newClient["phone"] = phone;
newClient["cellphone"] = cellphone;
newClient["email"] = email;
newClient["city"] = city;
newClient["stock"] = stock;
newClient["source"] = source;

var token = document.getElementById("csrf_token").content;
var requestSaveAddClient = new XMLHttpRequest();
requestSaveAddClient.onreadystatechange = function() {
    console.log("orsc: ", requestSaveAddClient.readyState);
};
console.log("Before open: ", requestSaveAddClient.readyState);
requestSaveAddClient.open( "POST", "newclient", true);
requestSaveAddClient.setRequestHeader("X-CSRF-TOKEN", token);
requestSaveAddClient.send(newClient);

有我的route.php:

    Route::post('newclient', 'DashController@store');

有我的DashController.php:

public function store(Request $request)
{
    $client = new Client;
    $client -> user_id      = Auth::user()->id;
    $client -> first_name   = Request::get('first_name');
    $client -> last_name    = Request::get('last_name');
    $client -> phone        = Request::get('phone');
    $client -> cellphone    = Request::get('cellphone');
    $client -> email        = Request::get('email');
    $client -> city         = Request::get('city');
    $client -> stock        = Request::get('stock');
    $client -> source       = Request::get('source');
    $client -> save();
    die();
}

dahsboard.blade.php:

                <div>
                <table id="addClientTable" name="addClientTable" class="addClientTable">
                    <meta name="csrf-token" id="csrf_token" content="{{ csrf_token() }}">

问题是XmlHttpRequest发送方法不能像你传递的那样使用数组,所以你尝试发送的参数不会进入控制器。

一个简单的替代方案可能是使用FormData对象。一个简单的例子可能如下所示:

var data = [
  {"year":2015, values:[1,2,3]},
  {"year":2016, values:[10,20,30]},
  {"year":2017, values:[100,200,300]}
];

我还强烈建议你做一些关于使用jQuery或类似东西的研究,以帮助你为你的网站编写脚本,这里有更多的学习曲线,但它会为你节省很多未来的时间和心痛,将使你成为一个更好的开发者。

Request::get('some_name')更改为Request::input('some_name');。对store方法中的所有输入执行此操作。

事实上,我会把这个功能清理干净......就像下面这样。我不会触及实际的javascript。它也不好。

$request->merge([
    'user_id' => Auth::user()->id
]);

$task = Client::create($request->all());
