This is how Alpha order is done @ Phpnuke (for members lists) - means how rows are being counted and limited

I couldn't implement it - 3 hours of trying .... my head is exploading

tzvook,

It should be possible to get all first letters of data in a column from the query results, but that would still require the query to get all results.

What I would do is create an extra column with the first letter of the category or title or whatever column you would like to use to filter on alphabet. Update the column with the first letters of the already existing data, and adjust the insert and update queries to fill this column based on the data entry.

Then you can adjust the query to only select records that match the letter in the "alphabetical" parameter in your url. This will not only speed up queries, it will also save calculation time.

Martijn


Yep, will speed up for sure, but then you'll need to do it also when editing a record, when users asking to modify it ....

Re: Xdirectory Alphabetic Order Hack ... need fresh eyes

Yes, upon saving and updating the listing, the script should get the first letter from the posted title. In the update query also update the first letter field.

I will use this concept in the directory module I am developing.

Hello Martijn
I'm trying to find out how it can be used as a wide system module hack, and the "letter" function is quite easy to implement @ modules like "MyLinks , Xdirectory , Xphones (Xdir hack) and so on" so help is needed in that area (can you look @ the code I posted from phpNuke ?)

I'm aware of your new project and waiting for the first release
but I'm looking a wider solution - that could be impolemented if needed to a lot of modules - the Alphabet search menu is quite importand for sites with 1000 members and above - especialy for modules that deals with phonebooks or members homepages - to my opinion, users are the heart of every site/system and as such , user interface needs to be the first concern of the developer (which xoops, though is an amasing system, is not so good at ... so I try to improove user's ability fo find things without the need to go to XOOPS search all the time).

Quite funny that no module has this option working correctly, 5 address modules in the Repository, non with alphabetic order ..... I want to make a hackd Xdir for that, but the "letters()" code is not acurate and as seen @ the PHPnuke ... is just part of the full code.

Tzvook,

Can you check which queries the MySQL debug window comes up with and post it to me when you click on the 'b' letter (list)?

I'm uploading it to my localhost site, as I can't do it on a "Live" site....
Probably a bit later ...

Hello Martijn
Sorry for the delay .... lots of holidays here ... too many
PHP/SMARTY/MYSQL debug gave me just a lot of theme problems along with Multimenue notices ....
I can see from the PHPnuke I posted above that the problem is that the "letters()" don't count the rows it gets from the database, the WFteam's "letters()" function seem to be based completely on that PHPnuke code... simply without doing it the right way ... a quick glance in the code shows it.
I'm not a coder (just a little playing around), so solving it is far from reach, though, I can see that the PHPnuke code is dealing with it ....
If you want to see the the Xdirectory (with the letters() but without the PHPnuke code ... here it is: http://www.meant4u.com/tmp/xdirectory.zip

The phpnuke code is above, hope it will make sense for you or any other coder here ... (it will serve the xdir + a few phonebooks + every module that it can be iplemented in ... a much needed addition for big sites that needs this sorting for getting to the data quicker...)

Hi
I'm currently working on providing another xdir version which employs this. I should have a beta out by next week sometime (maybe sooner). Just thought I would mention in case you're not in a huge rush.

Though I have yet to work on the alpha code, off of the top of my head I would use hard code the A|B|Cs as links to a new page (alphaCat.php -copy of viewcat.php) using alpha=A as a var. and then perform a SQL LIKE $alpha%. That way you don't need to change anything in the db, or the existing files (except inserting the hardcoded A|B snip).

More soon.

Tripmon,

What kind of new xdirextory are you making? Any new features that will be in efqDirectory as well?

Hello tripmon
Rush ... Desperation is the word ... site is on the air, phonebook has ~ 600 records which sort weirdly aufull, like I mentioned in the begining.
All are mad about me that I told them to fill the phonebook, and I couldn't find any solution

I think the letters() should work good ... just that the WFteam didn't took the whole code for it... ... were it counts the database rows.

It's working in some of the letters fine, but with others it don't ... if you try my Xdir version you'll see.
I would have pointed you to a live site, but you probably can't read Hebrew...

Did I mentioned how lost I am ? ? ?
I thought of using it for "Homepages" module too, but the Xdir problem is killing me.


wtravel
Can you look @ the code, tell me if it can be done ?
