Have you tried “Conditional Logic” (https://codex.wordpress.org/Conditional_Tags)? There’s also a “Dynamic Widgets” plugin (https://wordpress.org/extend/plugins/search.php?q=Dynamic+Widgets) I’ve found that works well!
Thanks @EyeMagicGraphics — I am using the Dynamic Widgets plug-in. It has a very peculiar glitch in it.
I created a static text widget in WP. Then I use Dynamic Widgets to have the static text widget appear only on a certain page and all of its child pages.
The glitch is that (from every WP & DynWidg setting I have tried) I can only get the text widget to appear on the child ages. I cannot get it to appear on the parent page.
So I give up after 4-5 days of effort and just want to go into the production of the sidebar code and hard code my widget.
I’ll have a look at your suggestion on “Conditional Logic” and see where that leads me.
@frank13 — there is no specific script for a do_action ( ‘abc123’ );
You have to register functions (hooks) that are invoked by the do_action — check out these pages from the WordPress Codex for more information on programming actions: https://codex.wordpress.org/Plugin_API
Thanks @RogerCoathup…poorly phrased question on my part.
I am looking for the code file or source document in WP/BP that contains the function `do_action( ‘bp_after_sidebar_me’ )`
it’s not a function itself… it’s a call to the do_action() function, passing ‘bp_after_sidebar_me’ as the parameter. The call is being made in sidebar.php in the bp-default template folder.
You can find these things by searching through a buddypress install in any good code editor / development environment.
do_action() itself is defined in the core WordPress files. In this case, do_action() will invoke any functions that you hook onto the bp_after_sidebar_me action.
Thanks again @RogerCoathup.
I continue to phrase my need very poorly.
I know about functions, calls, etc. I also know where `do_action( ‘bp_after_sidebar_me’ )` is located…that’s how I honed in on needing to track it down.
Here’s what I need to do:
I need to get in the process when `’bp_after_sidebar_me’` is happening as a result of the `do_action()` call.
I need to add some hard coding when this process is taking place.
So it’s the location/file/script/doc (whatever it ends up being called) within WP that I am looking for when `do_action( ‘bp_after_sidebar_me’ )` is happening.
Continuing to dig 
Then you need to add an action that hooks in the function you want to run:
add_action ( ‘bp_after_sidebar_me’, ‘my_function’ );
If you read the link I gave earlier, it explains how this action whole process works.
Here’s why I need to get into the code @RogerCoathup:
I have a page called Business.
Off Business, I have about 10 child pages.
I created a static-text widget. I used every conceivable settings combination within Dynamic Widgets to get the static-text widget to appear in the right-sidebar of Business and all of its Child Pages.
The widget is positioned in the middle of the right sidebar — not the top and not the bottom.
I can only get the static-text widget to appear on the Child Pages. Not the parent page.
So I give up and want to hard code it within the process of the right-sidebar build.
How does adding my own function get me to where I want to be?
I simply need to get to the script that produces that right sidebar so I can hard code my content.
I have no idea what I would even code in my won function to make this happen.
Gave up and hard coded inside the sidebar.php template
