Changing div value dynamically, navigation bar on laravel blade

Solution:

Laravel provides a built-in function you can use: Request::is().

From the API docs:

Determine if the current request URI matches a pattern.

You use is like this:

Request::is('about'); // returns a boolean

<a href="about" @if(Request::is('about')) class="active" @endif>

You could write a helper function to take care of it:

function isActive($path, $class = 'active')
{
    return (Request::is($path)) ? $class : '';
}

Put it in a file called helpers.php in your app directory and include it in the autoload-part of your composer.json like this:

"autoload": {
    "files": [
        "app/helpers.php"
    ]
},

Maybe you need to do a composer dump-autoload in your terminal.

And finally use it like this:

<a href="about" class="{{ isActive('about') }}">About</a>
