Release note / Piwigo 2.7.0

Upload Form

The web upload form has been rewritten. The new upload form in Piwigo 2.7 is based on HTML5 instead of Flash, it means a better compatibility with modern web browsers as well as an increased reliability using slow connections, thanks to chunked upload. Drag & drop will make photo selection much easier from your file browser!

Advanced feature : now you can upload any file type. In your local configuration, set conf['upload_form_all_types'] = true; and Piwigo will let you upload any file matching $conf['file_ext']. If you activate a plugin like VideoJS, you will be able to upload videos. Piwigo will automatically generate a representative picture for your videos and PDF files.

Take a Tour

The new plugin "Take a tour" is a live guide within your Piwigo. Activate it and follow the steps! There are currently 3 tours available: "first contact", "privacy" and "new features in 2.7". More to come!

Batch Manager

A search filter has been added to the batch manager. It comes with a powerful syntax to search for photos on dates, tags, size, file name and also search options like exact match, AND/OR, grouping, exclusion. Detailed help is available, just click on the (?). The same powerful syntax applies to the quick search field on the public side menu.

In the Batch Manager, find duplicates not only on file names but also on date & time and width & height

Still in the Batch Manager, find your photos with the new filter on file size.

Easy action link to empty your caddie in just one click.

Search Form

The Search page has been reworked: ability to select properties on which the word search applies, list of authors found in database, auto-complete list of tags, auto-complete list of albums...

Photo Edit

You can now edit the time as well as the date on photos.

When editing a photo, you can click on its thumbnail to open a bigger size, without leaving the page.

User Comments

You can disable the website field in user comments.

Sort Albums by Date

Now you can sort your albums based on the photos creation date or posted date.

Filter plugins

New filter to find your plugins easily before install. With 150+ plugins compatible with Piwigo 2.6, it's more than helpful!

58 languages

Piwigo 2.7.0 adds two new languages: Basque (Euskara) and Luxembourgish (Lëtzebuergesch). Your participation is welcomed on Piwigo.org translation platform, for new languages, improvements and new strings to translate in Piwigo core but also in plugins and themes. There are many strings to translate so we really need help from Piwigo community!

Technical features

Please note that more detailed documentation is available about Technical changes in Piwigo 2.7. Please read it to make your extensions compatible with Piwigo 2.7.

Caches

Two caches were added to improve global performances on large galleries (with tens of thousands of photos and more).

• The first one is a server side persistent cache which stores in files the result of specific big SQL queries; this speeds-up the load of the public pages.
• The second one is a client side cache which stores in your browser the full lists of tags/albums/users/groups; this speeds-up the load of admin pages with such select boxes.

Replacing TokenInput and Chosen by Selectize (details)

We dropped two JavaScript libraries used for the multiple-selection of albums and tags in favor of Selectize, much more powerful and versatile. It is also used for users and groups.

Exclude folders in files sync

Piwigo by default ignores folders "thumbnail", "pwg_high" and "pwg_representative" when syncing files. Now you can tell it to ignore some other folders by filling the $conf['sync_exclude_folders'] parameter with LocalFiles Editor plugin.

user_id field size

The database fields storing the user identifier have been increased to 8 digits, allowing up to 16M users (previously limited to 30k).

Password reset keys expiration

The "one-use" key sent by email when a user requests to reset his password expires after one hour. To increase security, the reset key is now stored as a hash.

Javascript libraries updated

Updated libraries: jQuery 1.11.1, jQuery UI 1.10.4, Colorbox 1.4.1. New libraries: jQuery UI Timepicker 1.4.4, Plupload 2.1.2 and Selectize 0.9.1.

Improvements for plugin creators

Plugins maintenance & auto-update (details)

A new special file called maintain.class.php has been introduced. It replaces the old maintain.inc.php file with more flexibility and handling of plugins manually updated (by FTP). The migration to this new system is advised but not mandatory.

Rename triggers functions (details)

Following what has been announced for Piwigo 2.6, the functions trigger_event and trigger_action have been renamed in trigger_change and trigger_notify. The old functions don't exist anymore.

conf_update_param() improvements (details)

conf_update_param function, used to create and update in-database configuration, got some nice enhancements: it automatically serialize and escape the input data and allows to update the global variable $conf as well.

Give include path to add_event_handler (details)

The function add_event_handler now accepts as 4th parameter the path a file to include before executing the callback. Don't do useless global imports anymore in your main.inc.php!

Option "force_fallback" for load_language

The fonction load_language got a new option named force_fallback allowing the tell Piwigo to always load the language file in a certain language (typically en_UK) before loading the actual localized file.

Theme colorscheme (details)

Theme creators are now advised to define $themeconf['colorscheme'] to "dark" or "clear" (and nothing else), in order to help plugins developers to choose the right stylesheet for their components.

Plugins and Batch Manager (details)

Three new triggers to allow plugins to add their own filters in the Batch Manager: batch_manager_perform_filters, batch_manager_register_filters, batch_manager_url_filter. perform_batch_manager_prefilters still exists for the special case of predefined filters.
