Improve support for loading the CSV file from an attachment or file using the src attribute

[bobbingwide]

There are a number of shortcodes, which have now been converted to blocks, that load content direct from the shortcode or block's content attribute. [bw_csv] also supports a src attribute. If there is no content and the value is numeric then the content is loaded from the attached file to the attachment with the given post ID. This may not have been used for a while.

I want to extend the logic for the following shortcodes and blocks

• [bw_csv] oik-bbw/csv
• [bw_css] oik-css/css
• [bw_geshi] oik-css/geshi
• [chart] sb-chart-block/chart
• [bw_graphviz] ?

Requirement

• Support loading of content from content, attachment file, local file or remote URL
• Ability the set the src attribute in the block editor

Proposed solution

• [x] Add shared library class ( Oik_attachment_contents ) to replace the existing logic to obtain the $contents_array.
• [x] Implement logic to support loading of a local file or remote URL
• [x] Add a text field to allow entry of the src attribute in the block editor
• [x] Write PHPUnit tests to validate the shared library content
• [x] Implement shared library file in relevant plugins
• [ ] Optionally, allow the filename to be entered as content - if it's a single line without the separator character

This doesn't appear to be working in blocks.wp-a2z.org for the shortcode. But the block does work on the front end.

<!-- wp:oik-bbw/csv {"src":"https://blocks.wp.a2z/wp-content/uploads/sites/10/2019/12/wp-plugins-blocks-20191109.csv"} /-->

On revisiting the post ( https://blocks.wp.a2z/about/block-catalogue-history/block-plugin-todo-list/ - ID 3994 ) the problem does not appear.

I didn't complete the optional task. Closing anyway.
