Under Construction

This proposal is under construction and is not ready for review.

Zend Framework: Zend_DataGrid Component Proposal

Proposed Component Name	Zend_DataGrid
Developer Notes	http://framework.zend.com/wiki/display/ZFDEV/Zend_DataGrid
Proposers	Aristide R. ZOUNGRANA Mihai BOJIN
Zend Liaison	TBD
Revision	1.0 - 11 September 2008: Initial Draft. (wiki revision: 11)

Zend_DataGrid is a component that displays the values of a data source in a table where each column represents a field and each row represents a record. The DataGrid component supports the following features:
Binding to data source controls, such as Zend_Db_Select, Zend_Db_Table, XML, CSV, RSS...Build-in columns capabilities (text, hyperlink, checkbox, radiobox, tree, template columns...).Built-in sorting capabilities.Built-in paging capabilities.Built-in row selection capabilities.Programmatic access to the DataGrid object model to dynamically set properties...Customizable appearance through styles.

2. References

3. Component Requirements, Constraints, and Acceptance Criteria

This component will provide extensibility to create automatically Html Table.
This component will provide XHTML valid output.

4. Dependencies on Other Framework Components

Zend_Exception
Zend_Paginator
Zend_Form_Element_*
Zend_View_Helper_*
Zend_Config_*

5. Theory of Operation

The component will displays grid in HTML, XML... formats with few renderers

6. Milestones / Tasks

Milestone 1: Initial class design
Milestone 2: Create prototype
Milestone 3: Finish proposal and submit for community review
Milestone 4: Create code-covering unit tests
Milestone 5: Initial documentation exists.

8. Use Cases

UC1: The model of data

class App_MyDataGrid extends Zend_DataGrid
{
    public function init()
    {
        parent::init();

        $id = new Inova_DataGrid_Column_Literal('#');
        $id->setHeaderText(' # ')
             ->setDataField('mnu_lis_id');

        $select = new Inova_DataGrid_Column_Checkbox('id');
        $select->setHeaderText('')
                   ->setDataField('mnu_lis_id');

        $radio = new Inova_DataGrid_Column_Radio('id');
        $radio->setHeaderText('Choix')
                 ->setDataField('mnu_lis_id');

        $title = new Inova_DataGrid_Column_HyperLink('title');
        $title->setHeaderText('Nom du menu')
               ->setDataField('mnu_elt_title')
               ->setTreeLevelDataField('mnu_list_tree')
               ->setDataUrlField('mnu_elt_id')
               ->setDataUrlFormatString($editActionUrl.'/id/%1$d');

        $alias = new Inova_DataGrid_Column_Literal('alias');
        $alias->setHeaderText('Alias')
                ->setDataField('mnu_elt_alias');

        $desc = new Inova_DataGrid_Column_Literal('desc');
        $desc->setHeaderText('Description')
                 ->setDataField('mnu_elt_desc')
                 ->addFilter('StringToLower');

        $link = new Inova_DataGrid_Column_Literal('link');
        $link->setHeaderText('Lien')
               ->setDataField('mnu_elt_link');


        $this->addColumn($id)
                ->addColumn($select)
                ->addColumn($title)
                ->addColumn($alias)
                ->addColumn($desc)
                ->addColumn($link);

        $this->setName('myListeGrid')
               ->setForm('mnuListeForm','mnu/liste')
               ->bindDataTable(new App_MyDbTable(),'findSqlSelect');

        return $this;
    }

}

UC 2 : In action controller

class Mnu_ListeController extends Intranet_Controller_Action
{
 ...
    public function indexAction()
    {
        $options = Zend_Config....

        $this->view->datagrid = new App_MyDataGrid($options);
        $this->view->datagrid->addPagerParam('paramForPaginationControl', $value);
        ...

    }

}

UC 3 : In view

datagrid->render(); ?>

UC 4: Simple usage, Only With datagrid view helper

$datasource = array(
                               array('columnName1' => 'columnValue1', 'columnName2' => 'columnValue2', 'columnName3' => 'columnValue3'),
                               array('columnName1' => 'columnValue1', 'columnName2' => 'columnValue2', 'columnName3' => 'columnValue3'),
                               array('columnName1' => 'columnValue1', 'columnName2' => 'columnValue2', 'columnName3' => 'columnValue3') );

echo $this->datagrid($datasource);
 
?
