Method 1: Creating a helper

I generally create a helpers.php file in the app folder, and add it to autoload section of composer.json:

"autoload": {
    "classmap": [
        ...
    ],
    "psr-4": {
        "App\\": "app/"
    },
    "files": [
        "app/helpers.php" // Add this file
    ]
},

In helpers.php, add the function as follows:

function generateForumURL($name, $id)
{
    // Using the url() helper, so you don't have to manually switch between
    // localhost and the production website name
    return url($name . "/" . $id);
}

Don't forget to run composer dump-autoload when you're done.

Method 2: Defining an accessor

Another way would be to simply add a getUrlAttribute to the Forum model, that returns the URL:

class Forum extends Eloquent {

    ...

    public function getUrlAttribute()
    {
        return url($this->name . '/' . $this->id);
    }

}

You can now use $forum->url as a string anywhere you like.

Using the link template

You can save the template as a view (I normally do it in a partials folder) and include it wherever you need:

File views/forums/partials/link.blade.php:

@if(isset($forum))
    <a href="{{ $forum->url }}">{{ $forum->name }}</a>
@endif

Include it in another views as follows:

@include('forums.partials.link', ['forum' => $forum])

And how can I use it now? I'm tried {{ generateForumURL('test', 'test') }} and I'm got Call to undefined function generateForumURL()

Run composer dump-autoload.

Parse error: syntax error, unexpected 'public' (T_PUBLIC) in C:\myadmin\htdocs\app\helpers.php on line 2 line 2 : public function generateForumURL($name, $id) first is <?php

Oops, my bad. As the error clearly explains, remove the public from the helper function.
