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

Just try this in your view :

{{ ControllerName::Functionname($params); }}

OR

<?php echo ControllerName::Functionname($params);?>

Refer this : http://laravel.io/forum/03-06-2014-what-is-the-proper-way-to-call-controllers-from-the-view?page=1

If you have a function which is being used at multiple places you should define it in helpers file, to do so create one (may be) in app/Http/Helpers folder and name it helpers.php, mention this file in the autoload block of your composer.json in following way :

"autoload": {
    "classmap": [
        "database"
    ],
    "psr-4": {
        "App\\": "app/"
    },
    "files": [
        "app/Http/Helpers/helpers.php"
    ]
},

run composer dump-autoload, and then you may call this function from anywhere, let it be controller view or model.

or if you don't need to put in the helpers. You can just simply call it from it's controller. Just make it a static function. Create.

public static function funtion_name($args) {}

Call.

\App\Http\Controllers\ControllerName::function_name($args)

If you don't like the very long code, you can just make it

ControllerName::function_name($args)

but don't forget to call it from the top of the view page.

use \App\Http\Controllers\ControllerName;
