php 通过laravel中的url传递变量

Passing a variable through url in laravel

提问by tom harrison

I'm fairly new to laravel and I'm struggling to get the format of my url correct.

我对 Laravel 还很陌生，我正在努力使我的 url 格式正确。

It formats as http://mysite/blog?category1instead of http://mysite/blog/category1

据格式，http://mysite/blog?category1而不是http://mysite/blog/category1

These are the files I am using. Is there a way to put the route into the BlogController?

这些是我正在使用的文件。有没有办法将路线放入BlogController？

Route.php

路由.php

Route::get('blog/{category}', function($category = null)
{
    // get all the blog stuff from database
    // if a category was passed, use that
    // if no category, get all posts
    if ($category)
        $posts = Post::where('category', '=', $category)->get();
    else
        $posts = Post::all();

    // show the view with blog posts (app/views/blog.blade.php)
    return View::make('blog.index')
        ->with('posts', $posts);
});

Blogcontroller

博客控制器

class BlogController extends BaseController {


    public function index()
    {
        // get the posts from the database by asking the Active Record for "all"
        $posts = Post::all();

        // and create a view which we return - note dot syntax to go into folder
        return View::make('blog.index', array('posts' => $posts));
    }
}

blog.index blade

blog.index 刀片

@foreach ($posts as $post)

    <h2>{{ $post->id }}</h2>
    <p>{{ $post->name }}</p>
    <p>{{ $post->category }}</p>
     <h2>{{ HTML::link(
    action('BlogController@index',array($post->category)),
    $post->category)}}


@endforeach

routes.php

路由文件

Route::get('category', 'CategoryController@indexExternal');

*.blade.php print the completed url

*.blade.php 打印完成的 url

<a href="{{url('category/'.$category->id.'/subcategory')}}" class="btn btn-primary" >Ver más</a>

I have added a new route in:

我在以下位置添加了一条新路线：

Route::get('blog/{category}', ['as' => 'post.path', 'uses' => 'BlogController@getCategory']);

and added a new link into index.blade:

并在index.blade 中添加了一个新链接：

<a href="{{ URL::route('post.path', [$post->category]) }}">{{ $post->category }}</a>

Instead of using a function as callback for your Route::getuse a controller and an action:

而不是使用函数作为您Route::get使用控制器和动作的回调：

Route::get('blog/{category}', 'BlogController@getCategory');

Now in your BlogControlleryou can create your function.

现在BlogController您可以创建您的功能。

class BlogController extends BaseController {

    public function index()
    {
        // get the posts from the database by asking the Active Record for "all"
        $posts = Post::all();

        // and create a view which we return - note dot syntax to go into folder
        return View::make('blog.index', array('posts' => $posts));
    }

    /**
     *  Your new function.
     */
    public function getCategory($category = null)
    {
        // get all the blog stuff from database
        // if a category was passed, use that
        // if no category, get all posts
        if ($category)
            $posts = Post::where('category', '=', $category)->get();
        else
            $posts = Post::all();

        // show the view with blog posts (app/views/blog.blade.php)
        return View::make('blog.index')
            ->with('posts', $posts);
    }
}

Update:

更新：

To display your links in your view, you should use HTML::linkActioninstead of HTML::link:

要在您的视图中显示您的链接，您应该使用HTML::linkAction代替HTML::link：

@foreach ($posts as $post)

    <h2>{{ $post->id }}</h2>
    <p>{{ $post->name }}</p>
    <p>{{ $post->category }}</p>
    {{ HTML::linkAction('BlogController@index', "Linkname", array('category' => $post->category)) }}

@endforeach

Have you tried using the alternative .htaccess as shown in the documentation? Here you go:

您是否尝试过使用文档中所示的替代 .htaccess ？干得好：

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

You need to place it in the publicfolder of your application.

您需要将其放在public应用程序的文件夹中。

Here is the original .htaccess in case you don't have it for whatever reason

这是原始的 .htaccess 以防万一你因为任何原因没有它

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

RewriteEngine On

# Redirect Trailing Slashes...
RewriteRule ^(.*)/$ / [L,R=301]

# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
