Simple Wordpress Plugin to count clicks on custom fields -- 2

I have a WordPress website for visitors to download files stored on my Google Drive. I am using WP Types plugin to create a custom field that I paste the Google Drive url in, and I render the link as a button inside a table like this: [login to view URL] the file download link is the orange/gold button that has the download icon and the words إضغط هنا للتحميل this table is php coded in the [login to view URL] file. I paste the google drive download link in this format: [login to view URL] I need a very simple code to track my downloads and display the number of file downloads. Details of what I need: --------------------------------------- 1- The code to be written as a Wordpress plugin so I can easily install it on multiple separate sites (NOT a multisite) and it automatically adds the appropriate tables into the database for each site. 2- I don't want to do extra steps (like adding the downloads to a custom post type or other. that's why I am not using a ready made "downloads" plugin. 3- I will be using caching plugins and Cloudflare CDN. so I need the plugin to cope with this. 4- I need a shortcode to show the number of downloads in each table. 5- I need a function with a shortcode to display the total number of downloads in the whole site. Maybe the solution is that the plugin needs store the data in a MySQL table, with a cronjob to clean up the counting (if you will use a table to count, and a table to store the final count). Each download file will be related to one post. so you can use the post ID to identify the download location. If there is a way to put a code around the custom field, so when it gets clicked it sends the post id to the database then echo the download number. I am quite open to suggestions if you have, but PLEASE DON'T bid on the job, then think of a solution later when you win the job. Thanks!
