Laravel: Get base url

Question

Simple question, but the answer seems quite hard to come by. In Codeigniter, I could load the url helper and then simply do

echo base_url();

Answer 1

Updates from 2018 Laravel release(5.7) documentation with some more url() functions and it's usage.

Question: To get the site's URL in Laravel?

This is kind of a general question, so we can split it.

1. Accessing The Base URL

// Get the base URL.
echo url('');

// Get the app URL from configuration which we set in .env file.
echo config('app.url'); 

2. Accessing The Current URL

// Get the current URL without the query string.
echo url()->current();

// Get the current URL including the query string.
echo url()->full();

// Get the full URL for the previous request.
echo url()->previous();

3. URLs For Named Routes

// http://example.com/home
echo route('home');

4. URLs To Assets(Public)

// Get the URL to the assets, mostly the base url itself.
echo asset('');

5. File URLs

use Illuminate\Support\Facades\Storage;

$url = Storage::url('file.jpg'); // stored in /storage/app/public
echo url($url);

Each of these methods may also be accessed via the URL facade:

use Illuminate\Support\Facades\URL;

echo URL::to(''); // Base URL
echo URL::current(); // Current URL

How to call these Helper functions from blade Template(Views) with usage.

// http://example.com/login
{{ url('/login') }}

// http://example.com/css/app.css
{{ asset('css/app.css') }}

// http://example.com/login
{{ route('login') }}

// usage

<!-- Styles -->
<link href="{{ asset('css/app.css') }}" rel="stylesheet">

<!-- Login link -->
<a class="nav-link" href="{{ route('login') }}">Login</a>

<!-- Login Post URL -->
<form method="POST" action="{{ url('/login') }}">

Answer 2

You can use the URL facade which lets you do calls to the URL generator

So you can do:

URL::to('/');

You can also use the application container:

$app->make('url')->to('/');
$app['url']->to('/');
App::make('url')->to('/');

Or inject the UrlGenerator:

<?php
namespace Vendor\Your\Class\Namespace;

use Illuminate\Routing\UrlGenerator;

class Classname
{
    protected $url;

    public function __construct(UrlGenerator $url)
    {
        $this->url = $url;
    }

    public function methodName()
    {
        $this->url->to('/');
    }
}

Answer 3

Another possibility: {{ URL::route('index') }}

Answer 4

You can also use URL::to('/') to display image in Laravel. Please see below:

<img src="{{URL::to('/')}}/images/{{ $post->image }}" height="100" weight="100"> 

Assume that, your image is stored under "public/images".

Answer 5

For Laravel 5 I normally use:

<a href="{{ url('/path/uri') }}">Link Text</a>

I'm of the understanding that using the url() function is calling the same Facade as URL::to()
