Some Yii2 work

Looking for someone to do some working on my website, basically the problem is I'm getting "Spammy structured data" from google webmaster because the website is missing some data like: author A value for the author field is required. datePublished A value for the datePublished field is required. headline A value for the headline field is required. image A value for the image field is required. publisher A value for the publisher field is required. warningdateModified The dateModified field is recommended. Please provide a value if available. warningmainEntityOfPage The mainEntityOfPage field is recommended. Please provide a value if available.
