如何指定使用哪种方法（存储和更新）laravel

Question

所以基本上我的 controller.php 中有存储功能和更新功能，我想知道如何指定在需要时使用哪种方法。我的代码进度如下图。有人对此有解决方案吗？

routes.php

Route::resource('manage_accounts', 'ManageAccountsController',
                ['only' => ['index', 'store', 'update']]);

view.blade.php

 <button class="btn btn-sm btn-warning" type="button"
          data-toggle="modal" data-target="#register" value="{{ $user->id }}">Edit&nbsp;<i class="glyphicon glyphicon-edit"></i></button>
 <button type="button" class="btn btn-info btn-md" data-toggle="modal" data-target="#register">Register New User</button>

 <!-- Modal -->
    <div id="register" class="modal fade" role="dialog">
        <div class="modal-dialog">

Answer 1

resource controllers 所做的一切就是为您提供一个方便的快捷方式：

Route::get('/resource',                 ['as' => 'resource.index',      'uses' => 'ResourceController@index'    ]);
Route::get('/resource/create',          ['as' => 'resource.create',     'uses' => 'ResourceController@create'   ]);
Route::post('/resource',                ['as' => 'resource.store',      'uses' => 'ResourceController@store'    ]);
Route::get('/resource/{resource}',      ['as' => 'resource.show',       'uses' => 'ResourceController@show'     ]);
Route::get('/resource/{resource}/edit', ['as' => 'resource.edit',       'uses' => 'ResourceController@edit'     ]);
Route::put('/resource/{resource}',      ['as' => 'resource.update',     'uses' => 'ResourceController@update'   ]);
Route::delete('/resource/{resource}',   ['as' => 'resource.destroy',    'uses' => 'ResourceController@destroy'  ]);

因此，如果您调用 Route::resource('manage_accounts', 'ManageAccountsController')，您将创建 7 条路线。您明确告诉 Laravel 只创建其中的 3 个，即这些：

Route::get('/resource',                 ['as' => 'resource.index',      'uses' => 'ResourceController@index'    ]);
Route::post('/resource',                ['as' => 'resource.store',      'uses' => 'ResourceController@store'    ]);
Route::put('/resource/{resource}',      ['as' => 'resource.update',     'uses' => 'ResourceController@update'   ]);

您可以通过请求这些路由 URL 来调用控制器上的这三种方法，例如您只需请求它 URL:

即可 'call' 索引路由

GET http://server/resource

当我查看您的标记时，我看到了这个表单标签：

<form class="form-horizontal" role="form" method="POST" action="/manage_accounts" novalidate>

这将在提交表单时创建此 HTTP 请求：

POST http://server.com/manage_accounts

将其与您的资源路由进行比较，这将最终调用您的控制器的 store() 方法。如果您希望该表单改为调用您的 update() 方法，则必须发出 PUT 请求。由于 HTML 表单 can't make PUT requests，Laravel 提供了一种使用表单模仿 PUT 请求的方法：

<form class="form-horizontal" role="form" method="POST" action="/manage_accounts/{{ $account->id }}" novalidate>
    <input type="hidden" name="_method" value="PUT" />

另请注意，url 表单发布到的目标已更改，并且应包含您要更新的实际帐户的 ID。

您可能还会发现将此与 artisan 自己认为的可用路线进行比较很有帮助。您可以通过发出 artisan 命令 $ php artisan route:list (Laravel 5) 或 $ php artisan routes (Laravel 4)

列出所有可用路由

使用 Store 方法在数据库中创建记录。用于编辑记录的更新方法。像示例创建方法 - 注册用户和更新方法 - 编辑配置文件
