I ran into a similar issue where I wanted to call a function defined in my controller from my view. Although it perplexed me for a while trying to figure out how to get to the controller from the view it turned out to be fairly straightforward.

I hand off an array to my views with data records that the view formats and presents to the user with jQuery DataTables (big duh). One column in the presented UI table is a set of action buttons that need to be created per row based on the content of the data in each of the rows. I guess I could have added the button definitions to the data rows as a column sent to the views but not all views needed the buttons so why? Instead, I wanted the view that needed them add them.

In the controller I pass a reference to the controller itself to the view as in

->with('callbackController', $this)

I called it callbackController as that is what I was doing. Now, inside my view I can either escape to PHP to use $callbackController to access the parent controller as in

<?php echo $callbackController->makeButtons($parameters); ?>

or just use the Blade mechanism

{!! $callbackController->makeButtons($parameters); ?>

It seems to be working fine across multiple controllers and views. I have not noticed a performance penalty using this mechanism and I have one huge table with over 50K rows.

I have not tried to pass on references to other objects (e.g., models, etc) yet but I do not see what that would not work as well

Might not be elegant but it seems to get the job done.

Instead of passing functions or querying it on the controller  I think what you need is relationships on models since these are related tables on your database   If based on your structure  input details and products are related you should put relationship definition on your models like this   public class InputDetail     protected  table    input details          other code   public function product       return  this- gt hasOne  App Product           then in your view you ll just have to say    lt p gt     input details- gt product- gt name    lt  p gt    More simpler that way  It is also the best practice that controllers should only do business logic for the current resource  For more info on how to do this just go to the docs  https   laravel com docs 5 0 eloquent relationships

Related to the question in your answer     You have multiple options to achieve this that are way better   Let s assume you have a model which you pass to the view    model   Model  find 1   View  make  view  - gt withModel  model     Now in your Model you could have a function   public function someFunction            do something     In your view you could call that function directly      model- gt someFunction       This is nice if you want to do something with the model  the dataset     If not you can still make a static function in the model   public static function someStaticFunction  var1   var2           do something     And then     App Model  someStaticFunction  yourVar1  yourVar2      Hope it helps
