how to access post date?

[MattAppleton]

We are trying to add a publish date to our metadata output (Lined in seems to want this!)

So far we tried just 'postDate' or a function like this added to seomate.php (see below) — with no joy!

Any advice on picking up the post date would be much appreciated!

 'additionalMeta' => [
        'og:type' => 'website',
         'datePublished' => function ($context) {
             $unformatted = $context->postDate;
             $formattedDate = array(date($unformatted, 'd m Y'));

             return $context;
         },

       
        'author' => [
            'name' => 'name here',
            'url' => 'url here',
        ],

        
    ],

Context is the whole twig context for the request. So if it's a given requests entry you're looking to get the publish date from, you'd do:

'datePublished' => function ($context) {
     return isset($context['entry']) ? $context['entry']->postDate->format('d m Y') : '';
 }

Please note that the closure should return a string with the value of the meta property. If the value is an empty string, it will be filtered out.
