Hi all

Someone knows how to create a default category like "Uncategorized" on install of a component?
I couldn't figure it out so far how this should be done correctly in my component.
I read somewhere something about a category.xml file we can use, but I didn't see any documentation about it. So maybe this was something discussed in Beta and got throwed out? I have no clue ;)

You could insert a SQL INSERT statement into the SQL install script for your component.

Code:
INSERT INTO `#__categories` VALUES
('', '', 1, '', '', 1, 'uncategorised', 'com_component', 'Uncategorised', 'uncategorised', '', '', 1, 0, '0000-00-00 00:00:00', 1, '{"target":"","image":""}', '', '', '{"page_title":"","author":"","robots":""}', 42, '2011-01-11 00:00:01', 0, '0000-00-00 00:00:00', 0, '*');

That was my first thought as well, but then the assets table doesn't get populated which then raises all sorts of errors when you try to modifiy this category.
At least I believe it's related to the assets table entries.

And you can't just insert an asset either because you have to recalculate the lft and rgt values for all parent items. You may need to include an install script with a function to insert the category, then the asset, then clean-up the asset table if you really want to include a category with your installation package.

Yes, I think so.
I guess there should be a Core function to do that, which could be called on install.
I see there is a new JCategories class in the core, but it doesn't look like it offers a function to do what I would need.

Or am I the only one who wants to create a default category for my component on install? All the Core applications seem to do this as well, but their life is easier :)

I came across your post when I was looking for the same thing. I'm pretty new at Joomla development, but I think I've got it worked out.

You need to create an installation script and then create the category in there. Something like this...

Code:
    /**
     * method to install com_whatever
     *
     * @param   JInstallerFile   $installer   The class calling this method
     *
     * @return void
     */
    public function install($installer)
    {
        // Create "uncategorised" category for component
        $basePath = JPATH_ADMINISTRATOR . '/components/com_categories';
        require_once $basePath . '/models/category.php';
        $config = array('table_path' => $basePath . '/tables');
        $catmodel = new CategoriesModelCategory($config);
        $catData = array('id' => 0, 'parent_id' => 0, 'level' => 1,
            'path' => 'uncategorised', 'extension' => 'com_whatever',
            'title' => 'Uncategorised', 'alias' => 'uncategorised',
            'description' => '', 'published' => 1, 'language' => '*');
        $status = $catmodel->save($catData);

        if(!$status)
        {
            JError::raiseWarning(500, JText::_('Unable to create default content category!'));
        }
    }


And of course make sure you replace "whatever" with your component name (or whatever).

I hope that helps!
