My current opinion : for Piwigo 2.1, let's go with FCBK. Then we will implement something like WordPress + improvement proposed by nicolas.

By looking more closely, it seems that none is ready to be used by us in an "optimized manner".
Unfortunately
- we cannot give FCBK directly a javascript object with all the available tags. I'm thinking to the caddie admin page in unit mode where we have N pictures and we have to pick from the same list
- we cannot tell FCBK not to create a new tag (by typing any text and pressing enter). I'm thinking at the search page on the public side
- I tried to play with it locally on an html page and some display bugs appeared when I changed the available tag list...

With my test on FCBK 2.6.1 (released on 15. December, 2009)

In select1 field, I have set "newel : false" => No way to create a new tag.
select1 and select2 are using the same list of tags.

Here is the POST content:

Array
(
    [select1] => Array
        (
            [0] => 145
        )

    [select2] => Array
        (
            [0] => 144
            [1] => Another new tag
        )

    [addTags] => Send
)

          $("#select1").fcbkcomplete({
            json_url: "fetched.txt",
            cache: true,
            filter_case: true,
            filter_hide: true,
            firstselected: true,
            filter_selected: true,
            newel: false
          });

          $("#select2").fcbkcomplete({
            json_url: "fetched.txt",
            cache: true,
            filter_case: true,
            filter_hide: true,
            firstselected: true,
            filter_selected: true,
            newel: true        
          });

I've used jQuery 1.3.2.

I admit I sometimes see bugs like "Loïc" 2 times in the suggest list.

I've propagated the new widget FCKB to batch mode.

I don't know if I met the same issues than rvelices, but indeed FCKB was not working efficiently with multiple instances on the same page. To fix that, instead of:

$(".tags").fcbkcomplete(

I wrote

$("#tags-5082, #tags-5080, #tags-5081, #tags-5079, #tags-5071").fcbkcomplete(

And it works nice then :-)

I should try it with 2011 tags (126953 associations)

The number of associations has no impact. But indeed 2011 tags is a lot (and the new widget is really better if you have 2k tags).

I have 137 tags only and it works really fast.

2011 is a lot, but it is not uncommon. There are libraries with hierarchical keywords sold out there with 10-20000 words.

1) managing Piwigo tags in a hierarchy
2) importing a tag hierarchy from metadata
3) importing rating from metadata

You got it right !

but Piwigo already has this feature, you can configure Piwigo to transform IPTC keywords into tags.

I did not see this feature. I need to dig deeper to find it.

1) managing Piwigo tags in a hierarchy
....

What makes Piwigo specific and able to use categories to manage hierarchical tags: the ability to associate a photo to several categories (most web applications can only associate an item to a single category and to multiple tags).

Yes, I understand that and I think that it a cool feature, although I would rather use it for sharing the pictures between 2 albums/categories. For example: I have a set of pictures taken in Vacation, but I want to share them in my Mountaineering album because they were taken on Mont Blanc ( this is actually a true example :) )

However, being able to import tags from digiKam/Lightroom will save me a lot of work when building the site. I can then perform searches and find all the pictures matching that tag even if they sit in different categories/Albums. Just to give you an example look at what Flicker does.

2) importing a tag hierarchy from metadata

Let's consider you have a photo with the following tags:
* places/USA/California/SanFrancisco
* animals/mammals/dog
...

d) generate the category hierarchy

I like d)  because it will include b) as well. Each photo will be tagged with all the tags from the hierarchy.  This way when yoy search for Mountain you will get pictures from the Rockies, Alps, Charpatians, Himalaya, but when you search by Chamonix you will get only the Alps pictures.

In addition a tree like tag management make sense, you can find already made tree out there and being  editable you can build upon them. I addition these will be standardized.

3) importing rating from metadata

This is good idea :-) we'll have to see how Lightroom/Digikam stores the rating in the photo metadata before converting it into a vote from the administrator user.

Can you create a feature request in the bugtracker for this?

Sure no problem.

Hello, Piwigo crew.

I just started a few days ago using piwigo for my image gallery.
It works fine in almost every aspect, but I've come to a problem with tag editor (fcbkcomplete).

First, it doesn't work if I leave it as it comes in your code; I have to add the element 'key' to the array of tags, making it like this:

  while ($row = pwg_db_fetch_assoc($result))
  {
    array_push(
      $taglist,
      array(
        'caption' => $row['tag_name'],
        'key' => $row['tag_name'],
        'value' => '~~'.$row['tag_id'].'~~'
        )
      );
  }

This fixes the problem in case there are no tags already attached to the image. With the tag list empty, I begin writing and the matching tags appear correctly under the textbox.

But if there are already tags assigned to the image, or after I assign the first tag, it doesn't work anymore. No tags are shown in the dropdownlist, and i have to type the word completely to add it to the image.

Is it just me, or are there any others with the same issue?
And, is there any way to fix it?

Thank you very much.

This bug have been fixed in Piwigo 2.2.1, but there is still an issue if tags already exists...
