如何使用Laravel 5返回数据

Question

I have problem with method AjaxController::InsertComment($comment,$name); not return $id variable into my ajax.bade.php. It insert data into database correctly but not return...

Here is my Ajax Controller:

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

class AjaxController extends Controller {

    /**
     * Display a listing of the resource.
     *
     * @return Response
     */

    public function __construct()
    {
        $this->middleware('guest');
    }

    public function index()
    {
        return view('ajax.ajax');
    }

    public static function InsertComment($comment,$name){

        $qv = DB::table('comments')->insert(                        
                      array(
                        'name'   => $name,
                        'comments_text' => $comment
                        )
                    );

        //$id = DB::table('comments')->insertGetId(array('name' => '[e-mail]', 'comments_text' => 'asdasdsa'));

        $id = DB::getPdo()->lastInsertId();


        return $id;


    }
}

Ok, I think I got you now. Suppose we have the following:

Example: ajax.blade.php

<div>{{ "Hi" }} </div>
    <script>
    $.post('/ajax', {
        '_token': $('meta[name=csrf-token]').attr('content'),
        task: "comment_insert",
        userID: _userID,
        comment: _comment,
        name: _name,
        userName: _userName,
        date: _date
    }).done(function( data ) {
        alert( "ID Loaded: " + data );
    });
</script>

Your controller should read like:

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

class AjaxController extends Controller {

    public function __construct()
    {
        $this->middleware('guest');
    }

    public function index()
    {
        return view('ajax.ajax');
    }

    public static function InsertComment($comment,$name)
    {
        $id = DB::table('comments')
                    ->insertGetId(array(
                        'name'   => $name,
                        'comments_text' => $comment
                    ));
        return $id;
    }
}
