To the original author:
Thank you for making this useful tool available. The leadership team of our volunteer organization is delighted with it.

Believe me, I know that the worst nightmare of any software contributor is a feature request that is only applicable to the requestor’s special case. It’s been a while, but I’ve been there. Nevertheless, I believe my particular case has broad applicability.

Having browsed the forum, I also understand that you have ended active support on this block several years ago. Nevertheless, I would like to present my use-case in the hope that either someone else has assumed support for the Sponsors block, or that you could give me a general overview of steps to use to modify the block.

Finally, the use case
Our volunteer organization asks our member organizations (also non-profit groups) for dues each year. Some pay quickly. Some drag out for one, two, or three months. This is because they wait until they have (infrequent) board meetings to approve any payments.

Our leadership would like the page to always be up-to-date. That means leaving the page alone until about 25% of the dues have been received, then deleting the 75% of the elements, then adding them back in one at a time. For each restoration, that means finding the symbol in Media Center, checking that I have the formal organization name, and finding the most appropriate link for the organization (often not the home page).

It would be much easier if each element (each row in the editor) had one more cell, containing a checkbox to indicate whether that row should be displayed or hidden.

I’m not inexperienced. I have programmed since 1965 and created web pages beginning with HTML1 in 1995. I have used Javascript and PHP. WordPress is new to me. A year ago I was told “You have 30 days to port the website from Drupal to WordPress–and we’re using an undocumented theme.” I’m now comfortable with the UI side, but know little about the infrastructure.

If you could provide me an overview like the following, I’d be happy to make the update available to WordPress users without charge.

1. How to access the current source
2. What area of the code has the UI (for setting/cancelling the checkbox)
3. What area of the code has the HTML generator (for reading the checkbox and executing/bypassing HTML generation for that table cell)
4. How to save the update to the server
5. How to update the documentation
6. How to contribute this to the WordPress project (if appropriate)

If Jan (the author) does not respond, could ANYONE please provide the answers to questions 1 and 4-6, I would be grateful. I’m sure my PHP and HTML skills and my decades of reverse engineering will permit me to answer questions 2 & 3 myself.

Thanks in advance,

Larry
