FSi DataGrid Component

List component that displays the items from collection (data source) by using special column objects. Displaying objects list is one of the most common tasks in web applications and probably the easiest one, so you could ask how this component can help you?

FSi DataGrid Component allows you to create one action that handle display all kind of lists in your application without duplicating code. It can be very useful in all kind of admin panel generators.

Basic Usage

The sample code shows more than a thousand words so lets start!

Before you can display data you need to add columns into DataGrid component. Columns pull data from objects using DataMappers (They will be described later).

Imagine a situation where we need to display a list of news. List must contains such information as:

• News ID
• News Title
• Author Name, Surname and email
• Publication Date
• Some basic actions like edit and delete

So we should get a table similar to the following:

And here is our News object.

Suppose that we use Doctrine ORM and we can get a list of objects as follows:

So if we have data we need to build grid and pass data into it.

We assume that datagrid.factory is a service with DataGridFactory object instance. More about creating DataGridFactory and loading columns into it will be described later.

DataGrid::addColumn($name, $type = 'text', $options = array());

Ok, so now when we have grid its time to create view. This can be done by calling DataGrid::CreateView()

$view is DataGridView object that implements \SeekableIterator, \Countable and \ArrayAccess interfaces so have easy access to each row in view.

Every single row in view must be DataGridRowView object that also implements \SeekableIterator, \Countable and \ArrayAccess interfaces so you have access to each column in row.

And the last view part, column is an object with methods like getAttribute, getValue and few other that will help you to build perfect view.

Here is a simple view implementation:

Heads up! There is a difference between using getColumns method at view and direct array access.

Installation

This section will describe how to add datagrid into your project. First thing is to get DataGrid sources, we recommend you to use composer After that you need to do a couple of things to create DataGridFactory that finally allows you to create DataGrid objects.

Here are sample scenarios of component usage:

• symfony

You can also add fsi/datagrid into composer.json and run composer.phar update or composer.phar install

Tests

Install PHPUnit To run tests for DataGrid you should install dev packages and run tests with commands:

Extensions

Extensions are something that makes DataGrid component extremely flexible, they are highly inspired by SymfonyForm extensions.

There are two kinds of extensions.

• DataGrid Extension
• DataGrid Column Extensions

DataGrid Extension are used to provide new column types, event subscribers even additional options for existing column types.

DataGrid Column Extensions purpose is to add new functionality to existing column types.

Each DataGrid Column Extension must be loaded by DataGrid Extension. Loading extension into DataGrid is nothing more than registering it in DataGridFactory.
