刀片模板，@ yield中的@yield（）

Question

This is my current implementation of the Open Graph tags using Laravel 5:

app.blade.php

<title>@yield('title')</title>
<meta property="og:title" content="@yield('og-title', 'DEFAULT PAGE TITLE')">
<meta property="og:image" content="@yield('og-image', 'default.png')">
<meta property="og:url" content="@yield('og-url', '{{ Request::url() }}')">
<meta property="og:site_name" content="SITE NAME">

page.blade.php

@extends('app')
@section('title', $article->title . ' | SITE NAME')
@section('og-title', $article->title)
@section('og-image', secure_url('img/news/' . $article->image .'.png'))

It works for the most part, but I have a couple inquiries:

1. Is there a way to use @yield() in @yield ?

   I tried <meta property="og:title" content="@yield('og-title', @yield('title'))"> but it did not work.

2. How can I get the current SECURE url of the page?

   {{ Request::url() }} returns http://example.com/page , but I want https://example.com/page

As a meta, please let me know if you have any suggestions to improve my current method of OG.

Answer 1

There is an easy way to achieve what you want. What you can do is to move the OG meta tags html to partial view, to which you can pass parameters on each page as you wish. For example in your master layout just create section for the og tags:

app.blade.php

<title>@yield('title')</title>
@section('ogtags')

@show

Now create your partial view let's call it:

og_tags.blade.php

<meta property="og:title" content="{{ $title or 'DEFAULT PAGE TITLE' }}">
<meta property="og:image" content="{{ $image or 'default.png' }}">
<meta property="og:url" content="{{ isset($url) ? $url : str_replace('http://', 'https://', Request::url()) }}">

So now in you views you can easily add og-tags like this:

home.blade.php

@extends('app')

@section('ogtags')
    @include('og_tags', ['title' => 'my title', 'image' => 'my-image.png'])
@stop

@section('content')
     your content here
@stop

For the secure url question, Request::url() returns the current url of the page, if it is via HTTPS it will start with https:// otherwise it will start with http:// . So this is why I just replace it to always be https

str_replace('http://', 'https://', Request::url())

If you wish to always have og_tags (in case your view does not define this section and you want to show default ones) you can just modify your app.blade.php like this:

<title>@yield('title')</title>
@section('ogtags')
    @include('og_tags')
@show

This is the cool part of Blade that you can split everything in smaller parts, then include them with dynamic parameters, or just create view composers to handle the data.

Answer 2

I always use a meta.blade.php and keep my meta separate from the main layout and not only meta but also, styles and scripts when possible and include then using @include(...) , anyways, but how to make it dynamic? In this case i use a similar approach like you but a little differently which let me full flexibility to make it real dynamic. Here is how I do it, probably it'll answer what you are seeking here. So, let's create a 'meta.blade.php' file and mine is given below:

<!-- Title-->
<title>@yield('title', smart('site.title'))</title>
<!-- Meta-->
<meta name="keywords" content="@yield('keywords', getSiteMeta('keywords'))" />
<meta name="description" content="@yield('description', getSiteMeta('description'))" />
<meta name="author" content="@yield('author', getSiteMeta('author'))" />
<!-- CSRF for AJAX-->
<meta name="csrf-token" content="{{ csrf_token() }}" />

Notice @yield('keywords', getSiteMeta('keywords')) so here; the getSiteMeta is a helper function which is declared in my app\\Helpers\\Common.php file and the function looks like this:

/**
 * Prapare meta Tags by $name
 * 
 * @param  String $metaname Meta Name
 * @return Meta Content
 */
function getSiteMeta($name)
{
    return smart("site.meta.$name");
}

Also another function is involved here, which is:

/**
 * Short cut to config call for smart.php file items
 * @param  String $str Config Key
 * @return String Config Value
 */
function smart($str)
{
    return config("smart.$str");
}

Actually, I've a config file of my own at config\\smart.php and smart is my site name so I've kept all of my site related configs in config\\smart.php which looks like this:

// config/smart.php
return [

    'site' => [
        'name' => 'Smart',
        'title' => 'Smart Title',
        'tagline' => 'Smart Tag Line',
        'meta' => [
            'keywords' => 'Smart Keywords',
            'language' => 'english',
            'description' => '...',
            'author' => 'Sheikh Heera'
        ],
    ],

    'role' => [
        'default' => 'genaral',  # By default, a user gets this role when registers.
        'reserved' => 'superuser' # Application's Admin must have this role assigned.
    ],
    // More...
];

Probably you got the idea, I can call smart('key_name') to get configs of my site so I don't need to use config('smart.key') and by default all the meta values are stored in my config/smart.php file so if I don't use a section like this:

@section('keywords')
    Some, Keywords, Here
@stop

Then I've always my default settings and by using a helper function getSiteMeta I have enough flexibility to change the logic of my function, for example, I can change the default source of my meta tags and can build it on the fly.

Regarding https it depends on your site, if you have used secured url ( ssl/https ) and Request::url() just returns what your current url is, so if it's https then it'll return that otherwise you'll get http .
