For the first thing just reverse the sorting order (works here at least).

• Use custom sort
  Sort spec %play_date%
• Reverse
  
  My %play_date% tag uses the following format: %Y-%M-%DT$H:$M:$S$T
  This means it's something like 2004-07-07T01:23:45-02:00.

Here's what settings I use (and which seem to work well..)

Query NOT %play_counter% MISSING
Search what database
Limit to 50 tracks

• Use custom sort
  Sort spec %play_date%
• Reverse
  
  My %play_date% tag uses the following format: %Y-%M-%DT$H:$M:$S$T
  This means it's something like 2004-07-07T01:23:45-02:00.

But this makes a problem, because if A mark a song as favorite but then B mark it as favorite, %favorite% keeps only the B value and remove song as A favorite. SO, A and B can't share favorites via this tag system

%favorite%A

In the QuickTag "A" field, type

Code: [Select]

%favorite%A

. This will retain any previous data in the favorite tag.

Note, however, that this will not prevent such data as "ABBA" etc. Therefore, you can either manually clean the data, or in your code to make the favorites list, use the [/I]$strchr(x,y) function to check if the tag contains "A" or "B".

In the QuickTag "A" field, type

Code: [Select]

%favorite%A

. This will retain any previous data in the favorite tag.

My %play_date% tag uses the following format: %Y-%M-%DT$H:$M:$S$T
This means it's something like 2004-07-07T01:23:45-02:00.

So that's what I try to achieve:

Old:
PLAY_DATE=%D%M%Y
PLAY_TIME=$H$M$S

New:
PLAY_DATE=%Y-%M-%D
PLAY_TIME=$H:$M:$S

Any suggestion? 

- In Masstagger, click 'Add'.
- Select 'Format value from other fields...'
- Destination field name: PLAY_DATE
- Formatting pattern: $right(%play_date%,2)-$substr(%play_date%,3,4)-$left(%play_date%,2)
- Click OK
- Repeat steps 1-2
- Destination field name: PLAY_TIME
- Formatting pattern: $left(%play_time%,2):$substr(%play_time%,3,4):$right(%play_time%,2)
- Click OK
- Back at the Masstagger main screen, click Run

I haven't tried it on my side, but it should work.

The second thing it's this: I'm using foobar in a 2 users PC, and I will like to tag favorites songs. Then I will like to generate with Extended playlist generator a playlist with favorites from user A and other with favorites from user B. This is what I came up with:

- Custom %favorite% tag field.
- Tag with Quicktag as 'favorite=A' to mark a song as A's favorite.
- Tag with Quicktag as 'favorite=B' to mark a song as B's favorite.
- Then use Extended playlist generator like this:
favorite IS A --> A' favorites playlist
favorite IS B --> B' favorites playlist

But this makes a problem, because if A mark a song as favorite but then B mark it as favorite, %favorite% keeps only the B value and remove song as A favorite. SO, A and B can't share favorites  via this tag system 

Do you have any ideas/suggestions about how you would do this?   [a href="index.php?act=findpost&pid=223510"][{POST_SNAPBACK}][/a]

I tried what Go2Null suggested me, but I didn't managed to setup 'Quick tag' plugin for doing that.

On the Quick Tag preferences page, set field name to "FAVOURITE" and value to "[%favourite%]A" or "[%favourite%]B". When you execute such an action, it will append "A" or "B" to the favourite tag. When no favourite tag exists, it will be created in the process.

I guess that what's impossible it's to avoid %favorite%=ABAAABAB (because of several tagging).... Is there a way to prevent for ex. favorite to be written as A, if A already exist in the value?

As mentioned by Go2Null, you could use the $strchr() function.[a href="index.php?act=findpost&pid=224558"][{POST_SNAPBACK}][/a]

Well, you could also take the easy road, and delete every A in the %favorites% tag before adding a new one. Just use "$replace([%favorites%],A,)A" as value of your quick tag action. (Sorry for not thinking of this in the first place.)
