Manage the Category Values?
15 May 2009 at 10:16pm
hey there,
is there a way to manage the Category values in the CMS?this is a part of Resource.php
static $db = array (
'Name' => 'Text',
'Description' => 'Text',
'Category' => "Enum('Industry, Finance, Education')"
);is it able to ADD / REMOVE / RENAME these Category in the CMS? when there are entries belong to an category that i want to delete, these entries should switch to an "holder" or "exil" category, or the category cant be deleted while there are entries belong to.
hm.. someone? ;)

Of course. First of all, you know that's just example code, right? It's by no means anything you have to use.
If you want dynamic categories, you could do something like this:
class ResourcePage extends Page
{
static $has_many = array (
'Categories' => 'ResourceCategory'
);// add to getCMSFields:
new TableField(
$this,
'Categories',
'ResourceCategory',
array('Name' => 'Name'),
array('Name' => 'TextField')
);
}class ResourceCategory extends DataObject
{
static $db = array ('Name' => 'Varchar(50'));
static $has_one = array ('ResourcePage' => 'ResourcePage');
}class Resource extends DataObject
{
static $has_one = array (
'Category' => 'ResourceCategory'
);
}
and then on your dropdown for categories, instead of the enumValues() function, just do this:$map = ($records = $this->ResourcePage()->ResourceCategories()) ? $records : array();
$dropdown = new DropdownField('CategoryID','Resource category',$map);
$dropdown->setEmptyString('-- Select category --');That's just pseudo code, but you get the idea.
