is there a way to nest {{}} expressions in Laravel template?

I have a resource route generated by Artisan command as

Route::resource('posts','PostsController');

the URI of this route is posts/{post}/edit which require a dynamic value in the middle. But because I'm using the url() method to link all of my routs I am forced to nest the template expression as:

<a href="{{url('/posts/{{$show->id}}/edit')}}" class="btn btn-sm">Edit</a>

This is giving me an error: NotFoundHttpException because it couldn't get the {{$show->id}} part. How can I fix this?

In PostsController, create a new variable that you want to show up in the template. You should be able to use the url() function within a controller. (See here) Pass this value to the template like you normally would.

  • At first sight you don't need the double {{ }} inside. Do just a single {}. Then another thing would be the single quotes enclosing the string param, I'd consider using double quotes. There's a question that suggests that below.
