Just checking. Have you found a solution for this?

hacked together a function for this

Code:

function getItemsViaCategoryId($id){
	global $mainframe, $option;
	$params 	= & $mainframe->getParams('com_flexicontent');
	$user	= & JFactory::getUser();
	$db 	= & JFactory::getDBO();
	$lang 		= JRequest::getWord('lang', '' );
	$where = ' WHERE rel.catid = '.$id;

	// Second is to only select items the user has access to
	$states = '1, -5';
	if ($user->authorize('com_flexicontent', 'state')) {
		$states .= ', 0 , -3, -4';
	}
	$where .= ' AND i.state IN ('.$states.')';
	$where .= ' AND i.sectionid = ' . FLEXI_SECTION;
	if (FLEXI_FISH) {
		$where .= ' AND ie.language LIKE ' . $db->Quote( $lang .'%' );
	}	
	$query 	= 'SELECT DISTINCT i.*, ie.*, u.name as author, ty.name AS typename,'
			. ' CASE WHEN CHAR_LENGTH(i.alias) THEN CONCAT_WS(\':\', i.id, i.alias) ELSE i.id END as slug'
			. ' FROM #__content AS i'
			. ' LEFT JOIN #__flexicontent_items_ext AS ie ON ie.item_id = i.id'
			. ' LEFT JOIN #__flexicontent_types AS ty ON ie.type_id = ty.id'
			. ' LEFT JOIN #__flexicontent_cats_item_relations AS rel ON rel.itemid = i.id'
			. ' LEFT JOIN #__categories AS c ON c.id = '. $id
			. ' LEFT JOIN #__users AS u ON u.id = i.created_by'
			.$where;
	$db->setQuery( $query);
	$db->query();
	$data = $db->loadObjectList();
	$items = FlexicontentFields::getFields($data, 'category', $params);
	return $items;
			
}

Excellent. Could you briefly describe how to use it in a template?

Thanks in advance!

copy paste the entire code in categories.php
in the subcategories in the

Code:

foreach ($this->categories as $sub) :

loop you could for example

Code:

$items = getItemsViaCategoryId($sub->id); 
foreach ($items as $item) :
//...now you can do your position magic
endforeach;

you can use almost the entire code in the items section, to show items from the same category.

Code:

just replace the line
$items = FlexicontentFields::getFields($data, 'categories', $params);

with

Code:

$items = FlexicontentFields::getFields($data, 'items', $params);

Honestly, I am grateful, but do not really know where to change or add what... :roll:

Any chance that you would explain in a little bit more detail?

Thanks a lot
