Store image caption

Hi Nickolas-

I have been using code you provided to another user a couple years ago (https://wordpress.org/support/topic/how-to-provide-post_title-post_content-post_excerpt/), and recently, the code stopped adding the caption to the uploaded image post. I have only one field with my upload form (Caption). In the plugin settings, I have specified to add images to the Media Library and to show Custom Fields in Media Library. I checked the WP database and the caption is stored in the postmeta table meta_key => _wp_attachment_metadata in a serialized array; however, the caption had been also added to the post table as post_title. This is no longer happening. The code I’m using is below.
