how do i pass role like ['admin','user','cmc'] some thing like this into the middleware of role

the problem is i can only get the first value in the array and the rest is not there can some one get me out of this

Answer 1

I had a similar situation where I wanted to check if a user is an owner or admin before visiting a route; so I didn't need duplicate routes, and needed to pass an array instead of set single parameters.

I went down the route of sending a single paramter but using an | as a delimiter to explode on the middlewhere class.

In the route I had this for the route group Route::group(['middleware' => ['checkRole:admin|owner']], function () {

and then in the middlewhere I used explode

$roles = explode('|', $permitted_roles);

Simple looped through the roles array to check if the user had one of the roles :) Hope this helps. Simple and easy for what I needed.
