I should have commented on the code you posted — sorry about that.

It looks as though you are trying to put all the indexes on the same page — at least I believe that’s what the code looks like it would do if you were not getting the syntax error. You can do this without any code — just by adding the short codes on after the other:

[az-index id="1"]
[az-index id="2"]
[az-index id="3"] and so on.

But don’t think that is what you want. In any case, you should not put that code in a the post_loop — I don’t think that has any chance of working the way you want it to. My best advice is to follow the instructions I gave above, and then all you will need in your blog index page is

[az-index id="23"] (or whatever the top-level index id is).

Let me explain.

When you created all those indexes (1-22) AZIndex also created a page for each of them (they will be created “unpublished”). Create one more index and set it to include “Pages Only” which have the tag “index” (or something similar).

Now, to add the “index” to the 22 index pages, you will have to install the plugin “tags4page” — http://wordpress.org/extend/plugins/tags4page/ — since WordPress doesn’t give you a way to tag pages (but they are supported once you add them). And so your top-level index is an index of other index pages. You should not have to write any code at all.

This may be a little work to set it up, but if you ever add a new category, all you have to do is create a new index for that category and add the “index” tag to the new index’s blog page and it will be added to the top-level index automatically.

Note: if you don’t want your index pages appearing in a list of pages (which some themes put on the home page) then make the top-level index page the parent page for all the other pages.

But is shows me this mistake:

Parse error: syntax error, unexpected $end in…

For example, if you have four categories — books, movies, music, television — you can create one index for each category, and you will also have created four new pages with those indexes on them. Next you can tag those index pages with a unique tag — “indexes” — and then create another index for all your other four index pages (select the “pages only” option in that index).

Note: if you like this idea, then you will have to install a plugin that will allow you to add tags to blog pages. I have used “tags4page” in the past — http://wordpress.org/extend/plugins/tags4page/ — which is simple to use. (There may be other plugins that do the same thing).

You can, of course, just create a static blog page which contains links to all your indexes, but the advantages of creating a top-level index is that when you add a new category and a new index, it will automatically be added to your top-level index (if you remember to tag it correctly) so there would be no need to edit the top-level index page.

If you only have a small number of categories — up to 20? — then that should be a workable solution. If you have many more than that, it would probably take a long time to set up (though you should only have to do it once). If you like the idea, test it out with a small number of indexes first to see if you like the results.

Let me know what you think.

I want to have your a-z index in every category (not index off all posts). In the first category (50 posts), second one (70 posts). Is any simple way how to do this?
