Hi, <\/p>\n

I thought of understanding better the nuts and bolts of WordPress core program during this slack period by reading the code and drawing a general flowchart for my own purpose. I have a few questions though: <\/p>\n

Screenshot of the program flow in question:<\/strong> https:\/\/prnt.sc\/xohtiz<\/a><\/p>\n

(Q1) I was wondering how do_action( “load-{$plugin_page}” ) gets triggered. Or rather, does add_menu_page “call” load-{$plugin_page} apart from load-{$page_hook}?<\/p>\n

(Q2) Is there any use case in the core that I could look at for this hook: do_action( “admin_action_{$action}” );<\/p>\n

The questions above aren’t for a specific project as such. This is a “back to basics” exercise in order for me to better structure plugins etc. Equally important, it will make me better diagnose issues that may come up with sites I maintain. <\/p>\n

Thanks in advance. <\/p>\n

Cheers.
