Thanks Liz, I very much appreciate it.
I saw that codex page too - I think Alan linked to it - most helpful indeed... but didn't get much on operators from it. It seems that each little branch of code languages has there own take on things; e.g., like Pear or CC, but not quite.
Am I correct in thinking that WordPress is entirely built on php and I'd be better off staying in that classroom rather than wondering lost in all of the school's hallways?
Okay, so, with much thanks and appreciation to you, Alan and the others posting in this thread, I've been successful in utilizing Widget Logic (test site - my latest science experiment: http://panocea.us/wp-test2/ - Widget Logic is absolutely just the right solution for my needs.
Using the conditional statements and logical operator:
is_single( '451' ) || is_home() I was able to display the text widget's html content in two places only.
Because the content in the widget is only on the home page for a while, an indeterminate period; day, month, whatever, the
is_home() will be later removed from that particular widget. And then the next update in that widget's featured location will own that space; for example,
is_single( '524' ) || is_home()
The thing I worry about now, is the one widget container could end up with hundreds of discrete text widgets all with their own peculiar widget logic / conditional statements. Is that about the way it is? or is there some other nifty means of managing the plethora of conditional statements that could reside in a single container?
The theme I using is Suffusion if that enters into the mix...
