具有多个参数的路由模型绑定

Question

In route.php, I have this:

Route::get('sells/{sells}/{slug}', 'SellsController@show');

In RouteServiceProvided.php, I have this binding:

$router->bind('sells', function($id, Route $route){
    $action = last(explode('@',$route->getActionName()));
    return ($action == 'edit')? Sell::isActive()->owned()->findOrFail($id) : Sell::isActive()->findOrFail($id);
});

As you see, I have nothing to do with {slug}. I want to know how can I pass the slug into the binding closure?

Any help is appreciated.

Answer 1

What gets passed to that closure is what it is, as your code isn't calling it, but the framework is. You could try getting the parameter from the route. In the closure you have you can pull the parameter:

$route->parameter('slug');

Answer 2

Like this

 function($id, Route $route) use( $slug ){
     //...........

http://php.net/manual/en/functions.anonymous.php

see example #3

This lets you pass in additional information at the time you define the closure, ( as opposed to when the closure is executed, with its call arguments )

Answer 3

If you don't really need to use "bind", use "get" or "post" instead:

$router->get('sells/{sells}/{slug}', function($sell, $slug)
{
    echo 'Sell ID: ' . $sell;
    echo '<br>';
    echo 'Slug: ' . $slug;
});
