![Embed for Kirby CMS](https://distantnative.com/remote/github/embed/logo.png)
[![Release](https://img.shields.io/github/release/distantnative/embed.svg)](https://github.com/distantnative/embed/releases)
[![Issues](https://img.shields.io/github/issues/distantnative/embed.svg)](https://github.com/distantnative/embed/issues) ![Kirby Version](https://img.shields.io/badge/Kirby-2.3%2B-red.svg)
Embed extends [Kirby](http://getkirby.com) with some extensive media embed functionalities. It enables Kirby to display embeds from various media sites (e.g. YouTube, Vimeo, Soundcloud, Instagram etc.) by only providing the URL to the medium. It is powered by the [oscarotero/Embed](https://github.com/oscarotero/Embed) library.

8. [Examples](#Examples)
9. [Help & Improve](#Help)
10. [Version History](#VersionHistory)
## Requirements <a id="Requirements"></a>
Kirby CMS 2.3.0+ and PHP 5.5+.
## Installation & Update <a id="Installation"></a>
1. Download [Embed](https://github.com/distantnative/embed/zipball/master/) and add the files to `site/plugins/embed/`
2. Add the necessary styles by including the following in the header:
```php
<?= css('assets/plugins/embed/css/embed.css') ?>
```
#### With video lazyload [option](#Options) (activated by default, include unless deactived)
3. Add the necessary script by including the following right before the `</body>` tag:
```php
<?= js('assets/plugins/embed/js/embed.js') ?>
```
#### With the [Kirby CLI](https://github.com/getkirby/cli)
```
kirby plugin:install distantnative/embed
```
And add CSS and JS as outlined above.
## Usage <a id="Usage"></a>
**As field method in templates:**
Use the method on fields that contain a url that points to a supported medium (e.g. YouTube, Vimeo, Twitter, Instagram, Spotify etc.):
```php
<?= $page->tweet()->embed(); ?>
```
You can use any text field containing a valid URL, but you might want to use the designated [Embed panel field](#Field).
**As Kirbytext tag:**
```
You'll be given love. You'll be taken care of. You'll be given love. You have to trust it. Maybe not from the sources. You have poured yours. Maybe not from the directions. You are staring at.
(embed: https://vimeo.com/43444347)
Twist your head around. It's all around you. All is full of love. All around you. All is full of love. You just ain't receiving. All is full of love. Your phone is off the hook. All is full of love. Your doors are all shut. All is full of love.
```
**As global PHP helper function:**
```php
<?= embed('https://www.youtube.com/watch?v=m2ua3O_fdCY') ?>
```
## Options <a id="Options"></a>
#### Per embed
You can set the following options on each embed to apply:
```php
// with the field method
<?= $page->featured_video()->embed([
'lazyvideo' => true
]) ?>
// with the Kirbytext tag
(embed: https://www.youtube.com/watch?v=IlV7RhT6zHs lazyvideo: true)
```
| Option | Values | Description |
|-------------|----------------|-------------------------------------------|
| `class` | (string) | Class to be added to the embed wrapper |
| `thumb` | (string) | Custom thumbnail (URL) |
| `autoplay` | `true`/`false` | Starts the embedded video automatically |
| `lazyvideo` | `true`/`false` | Lazyload the embedded video |
| `jsapi` | `true`/`false` | Activates the JS API of certain providers |
#### Global
You can set the following options in your `site/config/config.php` to generally apply to all embeds:
```php
c::set('plugin.embed.video.autoplay', false);
c::set('plugin.embed.video.lazyload', true);
c::set('plugin.embed.video.lazyload.btn', 'assets/plugins/embed/images/play.png');
c::set('plugin.embed.caching', true);
c::set('plugin.embed.caching.duration', 24); // in hours
c::set('plugin.embed.w3c.enforce', false);
c::set('plugin.embed.providers.jsapi', false);
c::set('plugin.embed.providers.google.key', null);
c::set('plugin.embed.providers.soundcloud.key', null):
```
#### URL parameters
Embed supports various URL parameters of provider that usually get lost during the embed call. To see which parameters are supported, please use the panel field and switch on the cheatsheet option.
## Panel field <a id="Field"></a>
Embed also includes its own panel field which provides a preview of the embedded medium right inside the panel:
```
// in your blueprint
…
fields:
…
featured_video:
label: Featured video
type: embed
```
With its additional options you can also disable the preview section, the information section as well as the cheatsheet or set a max-height for the preview:
```
fields:
…
featured_video:
label: Featured video
type: embed
preview: false
info: false
cheatsheet: false
height: 250px
```
![Panel field preview](https://distantnative.com/remote/github/embed/field2.png)
![Panel field preview](https://distantnative.com/remote/github/embed/field3.png)
## Advanced <a id="Advanced"></a>
Embed does not only provide you an easy way to output the embed code, but also gives you access to a whole array of additional information provided by the [oscarotero/Embed](https://github.com/oscarotero/Embed) library.
```php
// instead of echoing the field method, use it for further details:
$page->video()->embed()->title()
$info = $page->video()->embed();
echo $info->description();
echo $info->authorName();
```
You can find a full overview of what information can be accessed in the documentation of the [oscarotero/Embed](https://github.com/oscarotero/Embed) library or also just [test your media URL](http://oscarotero.com/embed2/demo) and see what information is available.
## Styles, Scripts & Translations <a id="StylesScripts"></a>
Embed comes with very minimal styles, mainly for embedded videos and only a small script necessary when lazyloading videos (activated by default):
```php
// Include styles
<?= css('assets/plugins/embed/css/embed.css') ?>
// Include script
<?= js('assets/plugins/embed/js/embed.js') ?>
```
If you want to further customize and work with the embedded medium. The following CSS classes are applied to the main wrapper:
```
.embed
.embed--{TYPE} // e.g. video, rich
.embed--{PROVIDER} // e.g. YouTube, Vimeo
.embed__thumb
.embed__thumb > img
```
You can also translate the strings used by Embed. Translations for English and German are already included. To find out what keys to use, check out the [English translation file](translations/en.php).
## Examples <a id="Examples"></a>
#### Blog: Featured Embed
```
// site/blueprints/article.yml
…
fields:
…
cover:
Cover photo
type: image
featured:
label: Featured embed (instead of cover photo)
type: embed
```
```php
// site/snippets/article.php
<article>
<aside class="entry-meta">...</aside>
<div class="entry-main">
<?php if($page->featured()->isNotEmpty()): ?>
<figure class="entry-cover">
<?= $page->featured()->embed() ?>
</figure>
<?php elseif($page->cover()->isNotEmpty()) : ?>
<figure class="entry-cover">
<?= $page->cover() ?>
</figure>
<?php endif; ?>
<div class="entry-content"><?= $page->text()->kt() ?></div>
</div>
</article>
```

PHP library to get information from any web page (using oembed, opengraph, twitter-cards, scrapping the html, etc). It's compatible with any web service (youtube, vimeo, flickr, instagram, etc) and has adapters to some sites like (archive.org, github, facebook, etc).
Requirements:
* PHP 5.5+
* Curl library installed
>
* If you need PHP 5.3 support, use the 1.x version
* If you need PHP 5.4 support, use the 2.x version
## Online demo
http://oscarotero.com/embed3/demo
## Installation
This package is installable and autoloadable via Composer as [embed/embed](https://packagist.org/packages/embed/embed).
```
$ composer require embed/embed
```
If you cannot (or don't want to) use composer, just include the [PSR-4 autoload.php file](src/autoloader.php) in your code.
## Usage
```php
use Embed\Embed;
//Load any url:
$info = Embed::create('https://www.youtube.com/watch?v=PP1xn5wHtxE');
//Get content info
$info->title; //The page title
$info->description; //The page description
$info->url; //The canonical url
$info->type; //The page type (link, video, image, rich)
$info->tags; //The page keywords (tags)
$info->images; //List of all images found in the page
$info->image; //The image choosen as main image
$info->imageWidth; //The width of the main image
$info->imageHeight; //The height of the main image
$info->code; //The code to embed the image, video, etc
$info->width; //The width of the embed code
$info->height; //The height of the embed code
$info->aspectRatio; //The aspect ratio (width/height)
$info->authorName; //The resource author
$info->authorUrl; //The author url
$info->providerName; //The provider name of the page (Youtube, Twitter, Instagram, etc)
$info->providerUrl; //The provider url
$info->providerIcons; //All provider icons found in the page
$info->providerIcon; //The icon choosen as main icon
$info->publishedDate; //The published date of the resource
$info->license; //The license url of the resource
$info->linkedData; //The linked-data info (http://json-ld.org/)
$info->feeds; //The RSS/Atom feeds
```
## The adapter
The adapter is the class that get all information of the page from the providers and choose the best result for each value. For example, a page can provide multiple titles from opengraph, twitter cards, oembed, the `<title>` html element, etc, so the adapter get all this titles and choose the best one.
Embed has an generic adapter called "Webpage" to use with any web but has also some specific adapters for sites like archive.org, facebook, google, github, spotify, etc, that provides information using their own apis, or need to fix any specific issue.
The available options for the adapters are:
Name | Type | Description
-----|------|------------
`min_image_width` | `int` | Minimal image width used to choose the main image
`min_image_height` | `int` | Minimal image height used to choose the main image
`images_blacklist` | `string|array` | Images that you don't want to be used. Could be plain text or [Uri](https://github.com/oscarotero/Embed/blob/master/src/Uri.php) match pattern.
`choose_bigger_image` | `bool` | Choose the bigger image as the main image (instead the first found, that usually is the most relevant).
## The providers
The providers get the data from different sources. Each source has it's own provider. For example, there is a provider for opengraph, other for twitter cards, for oembed, html, etc. Some providers can be configured and are the following:
### oembed
Used to get data from oembed api if it's available:
Name | Type | Description
-----|------|------------
`parameters` | `array` | Extra query parameters to send with the oembed request
`embedly_key` | `string` | If it's defined, use embed.ly api as fallback oembed provider.
`iframely_key` | `string` | If it's defined, use iframe.ly api as fallback oembed provider.
### html
Used to get data directly from the html code of the page:
Name | Type | Description
-----|------|------------
`max_images` | `int` | Max number of images fetched from the html code (searching for the `<img>` elements). By default is -1 (no limit). Use 0 to no get images.
`external_images` | `bool|array` | By default is false, this means that images located in other domains are not allowed. You can set true (allow all) or provide an array of url patterns.
### google
Used only for google maps to generate the embed code.
Name | Type | Description
-----|------|------------
`key` | `string` | The key used [for the embed api](https://developers.google.com/maps/documentation/embed/)
### soundcloud
Used only for soundcloud pages, to get information using its api.
Name | Type | Description
-----|------|------------
`key` | `string` | The key used to get info from soundcloud API.
## Example with all options:
The options are passed as the second argument as you can see in the following example:
```php
$info = Embed::create($url, [
'min_image_width' => 100,
'min_image_height' => 100,
'images_blacklist' => 'example.com/*',
'choose_bigger_image' => true,
'html' => [
'max_images' => 10,
'external_images' => true
],
'oembed' => [
'parameters' => [],
'embedly_key' => 'YOUR_KEY',
'iframely_key' => 'YOUR_KEY',
],
'google' => [
'key' => 'YOUR_KEY',
],
'soundcloud' => [
'key' => 'YOUR_KEY',
],
]);
```
## The dispatcher
To dispatch the http request, Embed includes the interface `Embed\Http\DispatcherInterface`. By default the curl library is used but you can create your own dispatcher to use any other library like [guzzle](https://github.com/guzzle/guzzle):
```php
use Embed\Embed;
use Embed\Http\DispatcherInteface;
use Embed\Http\Url;
use Embed\Http\Response;
use Embed\Http\ImageResponse;
class MyDispatcher implements DispatcherInterface
{
public function dispatch(Url $url)
{
$result = function_to_execute_request($url);
return new Response($url, $result['url'], $result['status'], $result['type'], $result['content'], $result['headers']);
}
public function dispatchImages(array $urls)
{
$responses = [];
foreach ($urls as $url) {
$result = function_to_get_image_size($url);
if ($result) {
$responses[] = new ImageResponse($url, $result['url'], $result['status'], $result['type'], $result['size'], $result['headers']);
}
}
return $responses;
}
}
//Use the dispatcher passing as third argument
$info = Embed::create('http://example.com', [], new MyDispatcher());
```
The default curl dispatcher accepts the same options that the [curl_setopt PHP function](http://php.net/manual/en/function.curl-setopt.php). You can edit the default values:
```php
use Embed\Embed;
use Embed\Http\CurlDispatcher;
$dispatcher = new CurlDispatcher([
CURLOPT_MAXREDIRS => 20,
CURLOPT_CONNECTTIMEOUT => 10,
CURLOPT_TIMEOUT => 10,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_SSL_VERIFYHOST => false,
CURLOPT_ENCODING => '',
CURLOPT_AUTOREFERER => true,
CURLOPT_USERAGENT => 'Embed PHP Library',
CURLOPT_IPRESOLVE => CURL_IPRESOLVE_V4,
]);
$info = Embed::create('http://example.com', [], $dispatcher);
```
## Accessing to advanced data
The adapter get the data from all providers and choose the best values. But you can get all available values accessing directly to each provider. There's also the possibility to inspect all http requests executed for debug purposes:
```php
use Embed\Embed;
//Get the info
$info = Embed::create('https://www.youtube.com/watch?v=PP1xn5wHtxE');
//Get all providers
$providers = $info->getProviders();
//Get the oembed provider
$oembed = $providers['oembed'];
//Get the oembed title value:
echo $oembed->getTitle();
//Get any value returned by the oembed api
echo $oembed->bag->get('author_name');
//Get the main response object
$response = $info->getResponse();
//Get any http response header
$lastModified = $response->getHeader('Last-Modifier');
//Get the html body as DOMDocument
$html = $response->getHtmlContent();
//Get all http request executed (oembed endpoints, images, apis, etc...)
$dispatcher = $adapter->getDispatcher();
foreach ($dispatcher->getAllResponses() as $response) {
echo 'The request to '.$response->getStartingUrl();
echo ' is resolved to '.$response->getUrl();
}
```
