Informations about the package dzend
DZend
DZend is a set of classes to wrap around Zend
. It' goal is to make common
patterns easier to implement and to transparently add commonly used
functionalities.
If a Zend class is wrapped at DZend, then it's name will be the same as the Zend
class but with a D at the beginning, but there is no abstract tables at DZend.
For instance, DZend_Db_Table
extends Zend_Db_Table_Abstract
.
Prerequisite
PHP 5.4 >=
Bootstrap
The bootstrap instantiate a few commonly used tools.
Logger
Instantiate Zend_Log
and write it on registry. To access this instance just
call:
Zend_Registry::get('looger');
All the logs will be written on the file public/tmp/log.txt
.
Internationalization
A Zend_Translate
instance is already included on the registry translate
.
Similarly to the logger, to access the translate object, call:
Zend_Registry::get('translate');
The detection of the locale is made automatically, in case none is found,
en_US
is the default.

Database
DZend_Db_Table
The class DZend_Db_Table
implements the __call
magic function to add a few
functionalities to select queries. For instance, let DbTable_User
extends
DZend_Db_Table
and represents the user
database table. To find all female
users, just use the call $userDb->findByGender('f')
, where $userDb
is an
instance of DbTable_User
. DZend parses the function name recognize the
columns.
The "And" can be used to separate column names. The method of format
findByColumnAAndColumnBAndColumnC($a, $b, $c)
will return a Zend_Db_Table_Rowset
containing all rows that have column_a = $a AND column_b = $b AND column_c = $c
.
To fetch just a Zend_Db_Table_Row
instead of a rowset, use findRowBy
,
instead of findBy
.
Similar to findBy
, there is also deleteBy
, which deletes all matching rows.
Registry Cache
If the class extending DZend_Db_Table
set $_allowRequestCache
to true, then
rows will be cached by ID, when using the methods findById
or findRowById
.
Beware that the cache lasts only during the request. Also, be mindful that
changed objects are not updated on cache. If an object is fetched and then updated.
Feching the object a second time will bring the old object.
insertMulti
Method
While Zend_Db_Table
provides a method insert
that inserts a single row,
DZend_Db_Table
provides the insertMulti
method that gets an array of data
arrays, to insert multiple rows.
DZend_Db_Table_Row
Usually SQL names for databases, tables and columns uses underscore notation
while programming uses camel notation. DZend_Db_Table_Row
automatically
converts between one another. Let $row
be an instance of DZend_Db_Table_Row
.
$row->columnName
can be used to access the column value for column_name
.
CurrentUser
The pre-requisite to get this trait working properly is to have the auth to
store the currently logged in user row on
DZend_Session_Namespace::get('session')->user
. It assumes that the id
attribute holds the primary key for the user.
DZend_CurrentUser
is a trait that provider two methods, _getUserRow()
and
_getUserId()
. In case there is not user logged, in it returns null
.
By default, DZend_Model
and DZend_Db_Table
already extends this trait.
