What is the TableListField class, and how do you use it in SilverStripe?

The TableListField class in SilverStripe is a component of the CMS that provides a user-friendly way to display and manage a list of related data records in a tabular format. It is commonly used for managing relationships, such as many-to-many associations or one-to-many relationships between DataObjects.

Key Features of TableListField

  • Data Display: Shows related records in a structured table format.
  • Editable: Allows for inline editing of certain fields.
  • Sorting and Filtering: Supports sorting and filtering capabilities for ease of data management.
  • Customization: Offers various options for customizing the display, including which columns to show and how to format them.

How to Use TableListField in SilverStripe

Step 1: Create Your DataObjects

First, you need to define the DataObjects that you want to manage. For example, consider a simple Author and Book relationship:

Example

<?php
use SilverStripe\ORM\DataObject;

class Author extends DataObject
{
    private static $db = [
        'Name' => 'Varchar(255)',
    ];

    private static $many_many = [
        'Books' => Book::class,
    ];
}

class Book extends DataObject
{
    private static $db = [
        'Title' => 'Varchar(255)',
    ];

    private static $many_many = [
        'Authors' => Author::class,
    ];
}
?>

Step 2: Create a CMS Page or Controller

In your CMS page or controller, you can create a TableListField to manage the relationship.

Example

<?php
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\GridField\GridField;
use SilverStripe\Forms\GridField\GridFieldConfig_RecordEditor;
use SilverStripe\Forms\GridField\GridFieldConfig_RelationEditor;
use Page;

class AuthorPage extends Page
{
    private static $has_many = [
        'Authors' => Author::class,
    ];

    public function getCMSFields()
    {
        $fields = parent::getCMSFields();

        // Create a GridField to manage the many-to-many relationship
        $gridField = GridField::create(
            'Books',
            'Books',
            $this->Books(), // The related data (Books)
            GridFieldConfig_RelationEditor::create() // Configuration for editing
        );

        // Add the GridField to the fields
        $fields->addFieldToTab('Root.Books', $gridField);

        return $fields;
    }
}
?>

Step 3: Configure the TableListField

You can customize the TableListField further by specifying which fields to show, applying filters, or enabling sorting:

Example

<?php
use SilverStripe\Forms\GridField\GridFieldConfig_RecordEditor;
use SilverStripe\Forms\GridField\GridFieldConfig_RelationEditor;

$gridField = GridField::create(
    'Books',
    'Books',
    $this->Books(),
    GridFieldConfig_RelationEditor::create()->addComponents(
        new GridFieldSortableHeader(), // Enables sorting
        new GridFieldFilterHeader() // Enables filtering
    )
);
?>
