Requirements

Installation and Configuration

From the command line run

composer require butschster/meta-tags

Once Meta Tags is installed you need to register the service provider. Just run artisan command

php artisan meta-tags:install

This command will install MetaTagsServiceProvider and will publish config config/meta_tags.php. In this config you can specify default title, keywords, description and other meta tags and its will be put into your HTML.

After running this command, verify that the App\Providers\MetaTagsServiceProvider was added to the providers array in your app config/app.php configuration file. If it wasn't, you should add it manually. Of course, if your application does not use the App namespace, you should update the provider class name as needed.

That's it!

Usage

Controller

You can use either Facade \Butschster\Head\Facades\Meta or \Butschster\Head\Contracts\MetaTags\MetaInterface in your controller

use Butschster\Head\MetaTags\MetaInterface;

class HomeController extends Controller {

    protected $meta;
 
    public function __contruct(MetaInterface $meta)
    {
        $this->meta = $meta;
    }
    
    public function index()
    {
        $news = News::paginate();
        
        // Prepend title part to the default title
        $this->meta
        
            // Will render "Home page - Default Title"
           ->prependTitle('Home page')
           
           // Will include next, prev, canonical links
           ->setPaginationLinks($news)
           
           // Will change default favicon
           ->setFavicon('/favicon-index.ico')
    }
}

// Or you can use the facade

use Butschster\Head\Facades\Meta;

class HomeController extends Controller {
    public function index()
    {
        $news = News::paginate();
        
        Meta::prependTitle('Home page')
            ->setPaginationLinks($news)
            ->setFavicon('favicon-index.ico');
    }
}

View

Just put this code {!! Meta::toHtml() !!} into your HTML and that's all.

you can use either {!! Meta::toHtml() !!} or @meta_tags

<!DOCTYPE html>
<html lang="en">
    <head>
        {!! Meta::toHtml() !!}
    </head>
    ...
</html>

Placements

If you want to use meta tags not only in header, you can specify placements in your templates. Use Meta::footer()->toHtml() or Meta::placement('placement')->toHtml() or @meta_tags('placement')

<body>
    ...
    {!! Meta::placement('middle_of_the_page')->toHtml() !!}
    ...
    {!! Meta::footer()->toHtml() !!}
</body>

Packages

I developed lots of web-sites and I solved lots of problems. One of them is code duplication and I decided I need a tool that allows me define groups of tags, assets, e.t.c in a package with name and use it wherever I want.

I can register a new package in \Butschster\Head\Contracts\MetaTags\MetaInterface

protected function packages()
{
   PackageManager::create('jquery', function($package) {
      $package->addScript(
         'jquery.js', 
         'https://code.jquery.com/jquery-3.3.1.min.js', 
         ['defer']
      );
   })
   
   PackageManager::create('calendar', function($package) {
      $package->requires('jquery');
      $package->addScript(
         'fullcalendar.js', 
         'https://cdn.jsdelivr.net/npm/@fullcalendar/core@4.0.1/main.min.js', 
         ['defer']
      )->addScript(
         'fullcalendar.locales.js', 
         'https://cdn.jsdelivr.net/npm/@fullcalendar/core@4.0.1/locales-all.min.js', 
         ['defer']
      )->addStyle(
         'fullcalendar.css', 
         'https://cdn.jsdelivr.net/npm/@fullcalendar/core@4.0.1/main.min.css'
      );
   });
}

And then if I need some package in one of my controllers I can do thing like this:

use Butschster\Head\Facades\Meta;

class EventsController extends Controller {

    public function show(Event $event)
    {
        // Will include all tags from calendar package
        Meta::includePackages(['calendar', ...])
    }
}

Or you can set packages, that can be included on every pages in config/meta_tags.php

...
'packages' => [
    'jquery', 'calendar', ...
],
...

That's all! It's very easy.

P.S. You can also use all methods, that are in Meta class.

Register a custom tag Our package has a lot of ways of extending. One of them is creating new tags. You are able to create a new class and share it with friends or with the laravel community. You can also create a new pull request if you think that your awesome tag is really useful.

class FacebookPixelTag implements \Butschster\Head\Contracts\MetaTags\Entities\TagInterface {

    public function __construct(string $id)
    {
        ...
    }
   
    public function placement(): string
    {
        return 'footer'
    }
    
    public function toHtml()
    {
        return '<script type="text/javascript">...</script>'
    }
}

Meta::addTag('facebook.pixel', new FacebookPixelTag('42b3h23-34234'));
// <script type="text/javascript">...</script>

Register tags from TagsCollection

$tags = new \Butschster\Head\MetaTags\TagsCollection([
    ...
]);
Meta::registerTags($tags);

// You can specify the placement 
Meta::registerTags($tags, 'footer');

Get a tag by name

Meta::getTag('author');

Remove a tag by name

Meta::removeTag('author');

Add a meta tag

Meta::addMeta('author', [
    'content' => 'butschster',
]);
// <meta name="author" content="butschster">

Add the CSRF-token tag

Meta::addCsrfToken();
// <meta name="csrf-token" content="....">

Remove all tags

Meta::reset();

Include required packages

Meta::includePackages('jquery', 'vuejs');
Meta::includePackages(['jquery', 'vuejs']);

Will load registered packages with names jquery and vuejs and append tags from there to Meta

Register a new package and register all tags from this package

Meta::setTitle('Current title');

$package = new \Butschster\Head\Packages\Package('custom_package');
$package->setTitle('New title');

// Will replace "Current title" to "New title" after package registration
Meta::registerPackage($package);

Meta extending

Meta object contains Macroable trait and you can extend it!

For example

//Service Provider
Meta::macro('registerSeoMetaTagsForPage', function (\App\Page $page) {
    $this
        ->prependTitle($page->title)
        ->setKeywords($page->meta_keywords)
        ->setDescription($page->meta_description);
 
});

// Controller
use Butschster\Head\Facades\Meta;

class PageController extends Controller {

    public function show(\App\Page $page)
    {
        Meta::registerSeoMetaTagsForPage($page);
    }
}

Meta tags placements

By default, tags place to head placement. You can specify your own placement and use their all available methods.


Meta::placement('twitter.meta')
    ->addMeta('twitter:card', [
        'content' => 'summary_large_image',
    ])
    ->includePackages('twitter')

// There is the method for footer placement
Meta::footer()->...
    
// View
<body>
    ...
    @meta_tags('twitter.meta')
    ...
    
    @meta_tags('footer')
</body>

Use cases

Multiple favicons

You can use your own package for that.

At first create your package in the MetaTagsServiceProvider App\Providers\MetaTagsServiceProvider

use Butschster\Head\MetaTags\Entities\Favicon;
use Butschster\Head\MetaTags\Entities\ConditionalComment;

protected function packages()
{
    ...

    PackageManager::create('favicons', function($package) {
        $sizes = ['16x16', '32x32', '64x64'];

        foreach ($sizes as $size) {
            $package->addTag(
                'favicon.'.$size, 
                new Favicon('http://site.com/favicon-'.$size.'.png', [
                    'sizes' => $size
                ])
            );
        }

        $package->addTag('favicon.ie', new ConditionalComment(
            new Favicon('http://site.com/favicon-ie.png'), 'IE gt 6'
        ));
    });
}

And then append this package into packages section in config/meta_tags.php:

...
'packages' => [
    'favicons'
],
...

And the every page you will see in the head seaction something like that:

<head>
    ...
    <title>...</title>
    <link rel="icon" type="image/png" href="http://site.com/favicon-16x16.png" sizes="16x16" />
    <link rel="icon" type="image/png" href="http://site.com/favicon-32x32.png" sizes="32x32" />
    <link rel="icon" type="image/png" href="http://site.com/favicon-64x64.png" sizes="64x64" />
    <!--[if IE gt 6]>
    <link rel="icon" type="image/png" href="http://site.com/favicon-ie.png" />
    <![endif]-->
    ...
</head>

Extending

If you want to extend Meta class you can do it in the App\Providers\MetaTagsServiceProvider. Just override registerMeta method.

use Butschster\Head\MetaTags\Meta;
use Butschster\Head\Contracts\MetaTags\MetaInterface;
use Butschster\Head\Contracts\Packages\ManagerInterface;

protected function registerMeta(): void
{
    $this->app->singleton(MetaInterface::class, function () {
        $meta = new Meta(
            $this->app[ManagerInterface::class],
            $this->app['config']
        );


        // It just an imagination, you can automatically 
        // add favicon if it exists
        if (file_exists(public_path('favicon.ico'))) {
            $meta->setFavicon('/favicon.ico');
        }

        $meta->includePackages('fonts', 'assets');
        
        // This method gets default values from config and creates tags
        // If you don't want to use default values just remove it.
        $meta->initialize();

        return $meta;
    });
}
You can’t perform that action at this time.
