Move your article’s data header to footer

After very busy work time I can write some other articles that I hope you find interesting.
I am involved in a large project for a news portal http://www.arezzonotizie.it/.
For this project I made some patches and writed some code personalization.
The first plugin I want to present is a mambot to move data from header to footer.
The standard joomla article's header show some elements in the header of the article:

  • pdf icon
  • print icon
  • e-mail icon
  • date created
  • author name

The mambot I have developed move all of this elements in the footer of the article.
As a bonus if the author have a linked contact, shows hyperlink to the correspondig author contact page.

Want a free layout for your cake?

If you want a layout for your new cake app and don't want to waste your time you can benefit of thousands of templates made for jOOmla.
The translation from joomla templates to cake layout is a very very simple job.

Let me explain from start:
A jOOmla template is composed of this main files and dirs

index.php - main template file
css/template_css.css - stylesheet file
images/* - all the images needed from stylesheet and main file

this can vary but this is the minimum requirements.

The first thing to do is to move the css/* files in your webroot/css
then move the images dir in your webroot.

webroot
|----css
|       template_css.css
|       cake.generic.css
|
|----img/*
|
|----images/*

If you wish to have only one dir for all your images then you must change all reference to images/ with img/ in your index.php and template_css.css

Now move your index.php file to your cakeroot/views/layout and rename it to default.thtml

Ok this is the 50% of job :).

Now we must modify the default.thtml file to meet cake requirements.

This a simple joomla template 2 (columns i used for one of my clients)
You can view how it renders here

The translation is very simple:
Replace mosMainBody(); jOOmla functions with echo content_for_layout;
And if needed replace the mosLoadModules() functions with renderElements()

Bypass jOOmla acl for automatic publishing

You knows that with jOOmla only publishers can publish there are situations with small groups I had requests for lowering the acl and permits to publish their articles also for authors. This is a very simple trick to do.

Locate these lines near the top of components/com_content/content.php

PLAIN TEXT
PHP:
  1. // Editor usertype check
  2. $access = new stdClass();
  3. $access->canEdit    = $acl->acl_check( 'action', 'edit', 'users', $my->usertype, 'content', 'all' );
  4. $access->canEditOwn = $acl->acl_check( 'action', 'edit', 'users', $my->usertype, 'content', 'own' );
  5. $access->canPublish = $acl->acl_check( 'action', 'publish', 'users', $my->usertype, 'content', 'all' );

And replace with:

PLAIN TEXT
PHP:
  1. // Editor usertype check
  2. $access = new stdClass();
  3. // ---------------------------------------------------------------------------
  4. // Marco 05.12.2005
  5. // Show publish in frontend even for authors
  6. // http://blog.nospace.net/
  7. // ---------------------------------------------------------------------------
  8. $acl->_mos_add_acl( 'action', 'publish', 'users', 'editor', 'content', 'all' );
  9. $acl->_mos_add_acl( 'action', 'publish', 'users', 'author', 'content', 'all' );
  10. // ---------------------------------------------------------------------------
  11. $access->canEdit    = $acl->acl_check( 'action', 'edit', 'users', $my->usertype, 'content', 'all' );
  12. $access->canEditOwn = $acl->acl_check( 'action', 'edit', 'users', $my->usertype, 'content', 'own' );
  13. $access->canPublish = $acl->acl_check( 'action', 'publish', 'users', $my->usertype, 'content', 'all' );

And then locate this lines:

PLAIN TEXT
PHP:
  1. } else {
  2.         $row->sectionid = $sectionid;
  3.         $row->version = 0;
  4.         $row->state = 0; // <<<<----------- replace 0 with 1 if you wish publish checkbox auto checked
  5.         $row->ordering = 0;
  6.         $row->images = array();
  7.         $row->publish_up = date( 'Y-m-d', time() );
  8.         $row->publish_down = 'Mai';
  9.         $row->creator = 0;
  10.         $row->modifier = 0;
  11.         $row->frontpage = 0;
  12.     }

that's all.

When model::getLastInsertId() is not enough.

There are situation where the very useful model::getLastInsertId() function is not enough.
For example if you are editing a records of an hasMany parts and you want to return to the list of records that belongsTo its parent.

Let me explain better:
