Laravel PHP，获得点击链接类

Question

I have a html5 table which is dynamically made from database items and it contains links, eg delete icon, which is in link tags <a href="xxxx" class="yyyy"></a> . I want to be able to click the delete icon and know, which item I want to delete. I have set class of the link the same as the relevant database items ID, but I cant read the class from the controller, after I click the link. Is there a method of doing that in PHP Laravel? Or maybe you could suggest a way better way to accomplish that? This seems a way off tactic for this.

Answer 1

If each row on the table represents a row on database, so your link could contain the id from database. For example, a user table.

Row 1 => Link /users/delete/1 
Row 2 => Link /users/delete/2 
Row 3 => Link /users/delete/3

By doing it this way, you can know for sure which one is called. On your routes file, if you are not using Route::resource() , you should have something like this:

Route::get('users/delete/{id}', 'UsersController@destroy');

And in your destroy method:

public function destroy($id) 
{
    // your logic here
}

Answer 2

Format your links as: If for example you are listing all items using foreach:

@foreach( $items as $item )
<a href="{{URL::to('/item/delete/'.$item->id}}">{{$item->name}}</a>
@endforeach

Inside routes.php

Route::get('item/delete/{id}', 'ItemsController@deleteItem');

inside ItemsController.php define the following function

public function deleteItem($id) {
  $item = Item::get($id);
  if( !$item ) App::abort(404);

  $item->delete();
  return Redirect::to('/');
}

and I am assuming you have your model in Item.php

class Item extends Eloquent {
  protected $table = 'items';
}

and your items table has id and name columns
