How to call a controller function inside a view in laravel 5

Please help me to resolve this issue.

Answer 1

You could try using ajax to call to function in a controller, then get the respones and push it to view. About respones, remember to put return in your function.

Answer 2

If your motivation for calling a controller method is just to output a string a controller may be inappropriate. Controllers bind models and views together.

Views really shouldn't be aware of controllers methods. You might be better off investigating view helper methods .

This is also answered in the question you link to

If you have a function which is being used at multiple places you should define it in helpers file

Answer 3

So I just tried this on one of my Laravel setups. I'm not sure if it's the best approach but it works.

Declare your function as

public static function my($args)
{
       echo $args."I am called on view.";
}

which you already did. then call it from the view as {{App\\Http\\Controllers\\Admin\\ReportController::my($args)}}

Answer 4

Use the absolute path instead relative path, you can use this as like below,

 \App\Http\Controllers\Admin\ReportController

but you have used App\\Http\\Controllers\\Admin\\ReportController , please change it in every places.
