Silverstripe Version: 4.2.1
Still new to Silverstripe, and can’t figure this one out. I’m creating a resources section (for PDFs, white papers, etc) as a DataObject and using another DataObject for categories for those resources. I have it setup so I can add individual resources and categories in the admin. My code is below, the important bit is probably CheckboxSetField::create('Categories', 'Categories', $this->Categories()->map('ID','Title')),. Haven’t learned how to fully use the docs yet (they’re overwhelming) so I’m sorta guessing the syntax based on the lessons. I get a section for categories in the resources but instead of checkboxes I get “No options available”. I’ve removed a few non-important sections of the code.
Resource.php
<?php
use SilverStripe\ORM\DataObject;
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\TextField;
use SilverStripe\Forms\HtmlEditor\HtmlEditorField;
use SilverStripe\Forms\OptionsetField;
use SilverStripe\Forms\CheckboxSetField;
class Resource extends DataObject
{
private static $db = [
'Title' => 'Varchar',
'Description' => 'HTMLText',
'ResourceType' => 'Enum(array("File","Link"))',
'Link' => 'Varchar',
];
private static $many_many = [
'Categories' => ResourceCategory::class,
];
private static $summary_fields = [
'Title'
];
public function getCMSFields()
{
$fields = FieldList::create(
TextField::create('Title'),
HtmlEditorField::create('Description'),
OptionsetField::create('ResourceType', 'Resource Type',
$this->dbObject('ResourceType')->enumValues(), 'File'),
CheckboxSetField::create('Categories', 'Categories',
$this->Categories()->map('ID','Title')),
TextField::create('Link')
);
return $fields;
}
}
ResourceCategory.php
<?php
use SilverStripe\ORM\DataObject;
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\TextField;
class ResourceCategory extends DataObject {
private static $db = [
'Title' => 'Varchar',
];
private static $belongs_many_many = [
'Resource' => Resource::class,
];
public function getCMSFields()
{
return FieldList::create(
TextField::create('Title')
);
}
}
