php - 搜索在 Laravel 5.1 中不起作用

Question

我目前正在做一个项目。在这个项目中，我无法使我的搜索表单正常工作。我的搜索按钮没有显示任何值。它只是返回一个空页面。请帮我。我的路线是

Route::get('/search', array('as' =>'search' ,'uses' => 'UserController@search'));

我的 Blade 模板是

<header id="header">
    <div class="top-bar">
        <div class="container">
            <div class="row">
                <div class="col-sm-12 col-xs-12">
                   <div class="social">
                        <ul class="social-share">
                            <li><a href="#"><i class="fa fa-google-plus"></i></a></li>
                            <li><a href="#"><i class="fa fa-facebook"></i></a></li>
                            <li><a href="#"><i class="fa fa-twitter"></i></a></li>
                            <li><a href="#"><i class="fa fa-skype"></i></a></li>
                        </ul>
                        <div class="search">
                            {!! Form::open(['route' => 'search', 'method'=> 'GET']) !!}

                                <input type="text" class="search-form" name="search" autocomplete="off" placeholder="Search">

我的 Controller 是

public function search(Request $req)
    {

        $divisions = Division::all();
        $doctors = Doctor::orderBy('name');
        $name = $req->input('name');
        if(!empty($name)) {
             $doctors->where('name', 'LIKE', '%' . $name . '%');
        }
        $doctors=$doctors->paginate(1);
       return view('users.index')
                   ->with('divisions',$divisions)
                   ->with('doctors',$doctors);

    }

Answer 1

您正在寻找 $req->input('name') 但您已在表单中将其命名为 search； 名称=“搜索”。

将您的输入更改为:

<input type="text" class="search-form" name="name" autocomplete="off" placeholder="Search">

或者您的 Controller 请求:

$name = $req->input('search');

您的表单似乎缺少提交按钮？

<input type="submit" value="Search">
