Creates link previews to pages with thumbnail, title and description

demo

Install

Via Composer

$ composer require jclyons52/page-preview

Usage

$previewManager = PreviewManager::create();
$preview = $previewManager->fetch('https://somewebsite.com');
echo $preview->render(); // returns bootstrap media link preview
echo $preview->toJson(); // returns json string of preview attributes

or do it inline:

PreviewManager::create()->fetch('https://somewebsite.com')->render();

Use another one of the other default templates:

$previewManager->render('thumbnail');

define your own templates:

$previewManager->fetch('https://somewebsite.com')->render('myAwesomeTemplate', '/path/to/template/directory');

caching

Http calls are slow, so to speed up your response times you may want to cache your previews. This package can take any psr-6 compliant cache driver as a parameter.

$pool = new Pool();

$previewManager = PreviewManager::create($pool);

$preview = $previewManager->findOrFetch('http://www.example.com/directory');

$previewManager->cache($preview);

The data available for you templates will be:

• string $title - meta title or page title if not found in meta
• string $description - meta description
• string $url - link url
• array $images - array of image urls
• array $meta - array of meta values with their names as keys

If you're usign information from tags such as the twitter meta tags (or anything seperated with ':') you may want to use the unFlatten function to get a multi level array.

This meta:

<meta name="twitter:card" content="app">
<meta name="twitter:site" content="@TwitterDev">
<meta name="twitter:description" content="Cannonball is the fun way to create and share stories and poems on your phone. Start with a beautiful image from the gallery, then choose words to complete the story and share it with friends.">
<meta name="twitter:app:country" content="US">
<meta name="twitter:app:name:iphone" content="Cannonball">
<meta name="twitter:app:id:iphone" content="929750075">
<meta name="twitter:app:url:iphone" content="cannonball://poem/5149e249222f9e600a7540ef">
<meta name="twitter:app:name:ipad" content="Cannonball">
<meta name="twitter:app:id:ipad" content="929750075">
<meta name="twitter:app:url:ipad" content="cannonball://poem/5149e249222f9e600a7540ef">
<meta name="twitter:app:name:googleplay" content="Cannonball">
<meta name="twitter:app:id:googleplay" content="io.fabric.samples.cannonball">
<meta name="twitter:app:url:googleplay" content="http://cannonball.fabric.io/poem/5149e249222f9e600a7540ef">

using unFlatten:

$meta = $preview->meta->unFlatten()['twitter'];

Would produce the following array:

[
    "card" => "app",
    "site" => "@TwitterDev",
    "description" => "Cannonball is the fun way to create and share stories and poems on your phone. Start with a beautiful image from the gallery, then choose words to complete the story and share it with friends.",
    "app" => [
        "country" => "US",
        "name" => [
            "iphone" => "Cannonball",
            "ipad" => "Cannonball",
            "googleplay" => "Cannonball",
        ],
        "id" => [
            "iphone" => "929750075",
            "ipad" => "929750075",
            "googleplay" => "io.fabric.samples.cannonball",
        ],
        "url" => [
            "iphone" => "cannonball://poem/5149e249222f9e600a7540ef",
            "ipad" => "cannonball://poem/5149e249222f9e600a7540ef",
            "googleplay" => "http://cannonball.fabric.io/poem/5149e249222f9e600a7540ef",
        ],
    ]

];
