Categories choice linked to section choice - backend
Hi,
When I publish an article, Is it possible to have a restricted choice of categories linked to section choice?
Ex.:
section1 > choice between cat.1 & cat2
section2 > choice between cat.3 cat.4 & cat.5
etc.
Thanks for your answers!

As far as I know, it’s not possible :(

Pieman’s right. At least, not directly possible. You’ll need a plugin for that. The tricky thing about it is the dynamic/AJAXy nature of the plugin. Each time you alter the section on the Write tab, you would need to dynamically alter the list of categories that are available. And if you’d already chosen a category that was not in the current section it would have to be emptied. It’s not beyond doable — I’ve written little unofficial plugins before to limit the available sections/categories based on user role/name for example — but it’s non-trivial, mainly in terms of configuration overhead.
btw, TXP 4.3.0 will make it easier to write this kind of thing. Not by an immense amount (the configuration panel on the back-end will still be the same song ‘n’ dance), but it should make the scripting side simpler and more robust

I think I understand the difficulty comes in when having multiple users editing. The script to display the sub-categories could hiccup if more than one person was editing.
But I’m the only person editing on my site.
Thanks.

If you are using categories only in 2 sections,
and only one category needed to be chosen while writing an article for each section,
so it’s not a problem.
I did it in my newest site and you can see it in action here and here (user&pass: TBD)
So how?
1. I used both Category1 & Category2 and just changed they labels to ‘Category’ using jQuery:
$("label[for='category-1']").replaceWith('<label for="category-1">Category</label>');
$("label[for='category-2']").replaceWith('<label for="category-2">Category</label>');2. I used jQuery again for deleting the categories I don’t want to be shown in each c1 & c2:
$("select#category-1 option[value='dj']").remove();
$("select#category-1 option[value='live']").remove();
$("select#category-2 option[value='cds']").remove();
$("select#category-2 option[value='digital']").remove();3. Using bot_write_tab_customize plugin to hide the entire c1 in section ‘Releases’ and hide the entire c2 in section ‘Artists’.
That’s it!
Of caurse a real good way of doing it will be better.
I think that we can somehow use the ‘bot_wtc’ plugin code for hiding fields base on sections to do the same with categories.
(after all isn’t it the same principle?)

Yes, it is indeed. To demonstrate here is a short and raw plugin that should do what you want. Of course it has no interface and you must configure it directly in the plugins code.
If you want to try just install it, press ‘edit’ in the ‘plugin’ tab and modify the lines under ‘configuration’.

Re: Categories choice linked to section choice - backend
Well, I have 2 sections.
One section is ‘about’ for my faq files. No categories under this section.
The other section is ‘articles’ where I put my categories. The upper level categories are: General, poems, Route 66, states, uncategorized, and webring. Under ‘States’ is a list of 50 state categories. Under each state category is a list of towns and cities categories that had/have drive-in movie theaters.
An example of the format under there is:
Sigh, still trying to figure out how to format text in the forums.
Here is how the categories under section article are set up:
Just scrolling down, when I started the move over was easy; however, since there were from 3000 to 5000 drive-ins in the US at one time… scrolling down that long of a list would be very time consuming. Texas had about 300 – 500 drive-in movie theaters, I presently have categories set up for 149 towns and cities in Texas.
So a means of having only the towns and cities show up in category 2 for the state I select in category 1 would be incredibly helpful.

Re: Categories choice linked to section choice - backend
Well, if that was available in the ‘write’ area so I could select a series of categories for each article, and the first category determined what was in list 2/category 2, yes, that would work.
