Hello,
this morning, i was just thinking about an interesting new ZF concept.
Imagine.
You got a class, let's say "News", which treats news on your website.
Datas for this class may come from everywhere : db, xml, csv, ....
The only requisite is that these datas must be indexed (this way, we can
do searches, inserts, deletes, ...)
Let's go for a schema, you'll quickly understand what i mean :
Zend/
Data.php
Data/
Adapter/
Abstract.php
Db.php
Xml.php
Config.php
...
Abstract.php implements common methods like finding, fetching,
inserting, updating, deleting, ....
Then, every adapter simply implements an existing (or not) ZF elements :
Db.php -> Zend_Db_Table
Xml.php -> Zend_Xml
Config.php -> Zend_Config
...
The code, now :
$news = Zend_Data::factory( $adapter, $config );
or
class News
{
protected $_data;
public function __construct($adapter, $config)
{
$this->_data = Zend_Data::factory( $adapter, $config );
}
}
or ...
Three (surely more ) greats aspects of this approach :
1) Totally abstracted and centralized data manipulation
2) We can connect Zend_Data directly to Zend_Form to make all ready
forms for one or more elements.
3) We can implement a Zend_Datagrid, which take a Zend_Data object for
source (and render it through Zend_Html_Table, or Zend_Pdf, or
Zend_Excel, ...)
It sounds good, no ?
