I’m proud to announce that the P4A screencasts channel opens today, turn on your TV or you’ll be late for the show!

The first screencast I’m publishing is about creating an hello world application, using a P4A_Button and some new system messages:

If you want to be a part of the P4A star system create your screencast and contact me, I’ll publish it on the TV :-)

We’re doing steps ahead, the P4A 3 feature set is almost complete!

In this release you’ll find that P4A is now based on Zend Framework 1.5 (released today) and a bunch of bugfixes and small modifications.

We’re releasing more and more P4A 3 based projects for our customers and we’re getting a lot of positive feedback, most of all for the speed of the full AJAX stack (as I like to call the new AJAX-only mode).

Another great news: we finally had time to work on P4A planet, which has been opened today, we already have 3 languages (english, italian and spanish) and we hope we’ll have more in the future. If you have a blog and you write about P4A just contact me! I’ll be happy to add your blog to the planet! We’re now working on the new wiki, just give us a few days to complete the work.

It’s time to release a new P4A 3 preview package! This mainly is a bugfix release, but we’ve a few interesting things out there, I started coding the new exception based error management and started porting some P4A components to it (or to “trigger_error” depending on the specific case). Zend Framework was updated to 1.0.4 and this raised a few issues I fixed (hope I found them all). Due to high demand I also worked on P4A_Sheet, supporting anchoring for text strings and re-creating the setFree method.

Here you have the full changelog:

Forum considerations:
You know P4A has a new fantastic spanish community, they created a new forum on google groups. I has a discussion with some users saying that sourceforge forums are ineffective because of the answers orders and few other things. We’ve to consider that, with P4A 3, 99% of the forum posts will become outdated, so the question is should we move P4A forums to google code or another service?

We always used SF forums because it’s one of the best ways to make the project activity rate raise and let P4A be one of the most active project all over SF. Moving the forum elsewhere will drop this positive effect. We also have to keep this is mind.

Please let me know your considerations!

Yesterday I saw a post by Daniel Carrero on P4A’s forums, talking about this new website:

A spanish blog talking about P4A. Isn’t it cool? I think it really is! Thank you Daniel!

Only 4 days after the 2nd P4A 3 preview release I’m here again for a new release, which is both a bugfix release and an API stabilization release.

Let’s go directly to the changelog which is not so long and complex:

- P4A_Mask::main() method is now called also within an AJAX call, if a full redesign is required
- a bug with search function within products_catalogue sample was fixed
- more chainability was added to the P4A main class
- a bug with P4A_DB_Source::createDataField() method was solved
- P4A_DB_Source::addJoin*() methods now supports null 3rd parameter (fields list)
- a bug with P4A_DB_Source::setFields() and aliases was solved
- README updated because P4A can’t handle db tables with numeric column names
- P4A_Validate class was added, it subclasses Zend_Validate and we need it to remove validators from a validator chain (ZF does not support that feature)
- P4A_Field::removeValidator() method was added
- P4A_Mask::unsetRequiredField() method was added
- P4A_Widget::removeCSSClass() method was added

This week I’ve been damn busy, we got so many feedback after the first P4A 3 preview release that I fixed some things and worked on some others.

Three important issues:

• with the full ajax implementation to boost the user experience we found a bug when you’ve to download a file within a mask, this has been solved creating some new methods to work with
• the README file was updated writing info about PDO, which was a FAQ in these days
• due to the high requests, P4A_Sheet was re-created from scratch with a P4A 3 design in mind

I think we all need a new preview to work on the most updated software, here you have the changelog:

- a bug with “preview” button within P4A_Field file upload was solved
- a bug with file download was fixed
- P4A::inAjaxCall() method was rewritten
- P4A_Redirect_To_File() global function was added
- a bug with images preview on ie/opera was solved
- README was updated
- P4A_Output_File() global function was added, it has to be used when you want to creare a file at run-time and make users download it
- Chainability support was added for P4A_Simple_Toolbar, P4A_Navigation_Toolbar, P4A_Full_Toolbar and P4A_Actions_Toolbar
- P4A_Tab_Pane padding was changed a bit
- P4A_Sheet was re-created

It’s been a hard developing week, I had to do a close some big tasks before the preview release, there are 4 most important points since the last commit digest:

• chainability
• all the code and libraries which did not fit our new licenses was removed or rewritten from scratch. I removed getid3, phpthumb libraries and the jquery color picker but I had to write from scratch a thumbnail generator, it’s been easy and we’ve a good cache support and PHP5 code, light and fast.
• P4A now has a “P4A_Login_Mask”, you can use it for login operations (usage within the P4A’s bundled samples) and it’s the only mask that’s allowed to do not display the “download source code” link in the footer zone
• last but most important: this surely is the fastest release ever, all the client/server interaction was rewritten, javascript/css files will be loaded only one time by the browser, than every call we’ll be done via ajax. It’s lighting fast and it works flawlessly, believe me

Here you have the changelog for this digest:

- P4A_DB_Source::load() method now autodetect schema name
- P4A_DB::nextSequenceId now automatically creates sequences on oracle too
- jQuery color picker was removed
- getId3 was dropped, we went back to getimagesize() PHP function to extract images information but we can’t retrieve video files information anymore
- phpThumb was removed
- P4A_Thumbnail_Generator was added
- P4A_DB::nextSequenceId now automatically creates sequences on postgreSQL too
- P4A_DB_Source compose count query was changed a bit to support PostgreSQL syntax
- P4A_Field does not preview images if GD are not installed
- P4A_Login_Mask was added, it should be used if your application needs a login system, it does not display the “download application source” link in the footer zone
- products_catalogue sample now uses the P4A_Login_Mask to show how to use this new feature
- P4A_Object::implementMethod() method was renamed to implement()
- P4A::getBrowserOS() method was added
- default and popup templates now add to #p4a_body a new CSS class containing the browser platform (windows, linux etc…)
- P4A_Error was removed because outdated, it will be replaced by exception objects
- README was updated
- P4A_Tab_Pane::getActivePageName() method was refactored, if empty returns the first page name
- P4A_Tab_Pane::getAsString() method now calls getActivePageName() to avoid the possibility to render a tab pane without any active page
- P4A_Mask_Preview was renamed to P4A_Preview_Mask
- P4A_Mask_Error was renamed to P4A_Error_Mask
- P4A_Canvas now is rendered inside a container div to have id/class/properties/actions
- all P4A objects now support chainability
- P4A_Image::setSource() and getSource() methods were removed
- P4A_Mask::addTempCss(), dropTempCss(), clearTempCss(), addJavascript(), dropJavascript(), addTempJavascript(), dropTempJavascript(), clearTempJavascript(), addCSS(), dropCSS() were removed
- default and popup mask templates were broken in 3 files, now header and footer and manager by P4A and templates have only the body part
- P4A::getPopupMaskName() and getPopupMask() methods were removed
- P4A_Mask::getP4AJavascript() method was moved to P4A::getJavascriptInitializations()
- ajax manager was completely reworked and now, if you have ajax enabled, you won’t see no refreshes at all, every action will be managed by ajax call with automatic redesign

It’s been an hard work, something like 500 commits and most of the code rewritten, now we need your help, please:

• translate P4A in your language
• test everything you can and report bugs
• write us in forums, we need to know what you think
