    Dear,

    I try to clean errors and warning I have with the google structured data tools.

    I have my “BlogPosting” pages working with site reviews.

    I’ve cleaned some errors adding this to my functions.php file :

    add_filter( 'site-reviews/schema/BlogPosting', function( $schema ) {
    $schema['author']['name'] = 'xxx';
    $schema['author']['type'] = 'Person';

   etc...

    return $schema;
});

    But I don’t know how to fix it for the dynamic datas :

    -datePublished
    -headline
    -dateModified

    Is there a solution to add those data without using another structured data plugin ?

    Thank you very much for your help.

    According to the official schema.org documentation:

    The datePublished value is expected to be the “Date” schema type.

    And the Date schema type is expected to be a date value in ISO 8601 date format.

    To do this in PHP:

    $date = '2019-03-18';
$datePublished = (new DateTime($date))->format(DateTime::ATOM);

    Thank you for your reply.

    My problem isn’t how to format the date, but how to have the Published date added automatically to the schema when I post a new article.

    I’d like to add something like :

    $date = get_the_date( 'Y-m-d' , $post_id );
$datePublished = (new DateTime($date))->format(DateTime::ATOM);
$schema['datePublished']=$datePublished;

    But I don’t see how to fix it. Is there a solution to get the Post ID or any other solution to make it works ?

    Have you tried using get_post()? This will return the global $post object.

    $post = get_post();

    Or:

    $postId = get_the_ID();

    It works perfectly.

    I don’t know why I didn’t try it, I was sure it won’t works…

    Thank you very much ??

    I paste the code if it can help others :

    $date = get_the_date( 'Y-m-d H:i:s' , get_the_ID());
	$datePublished = (new DateTime($date))->format(DateTime::ATOM);
	$schema['datePublished']=$datePublished;
	
	$date = get_the_modified_time( 'Y-m-d H:i:s' , get_the_ID());
	$dateModified = (new DateTime($date))->format(DateTime::ATOM);
	$schema['dateModified']=$dateModified;
