  1. I've been searching for a science that will solve this analysis problem. Since I don't know what I'm looking for, I cannot properly express the task to accomplish. I have an eCommerce store selling a product that has (let's keep it simple) three properties and each property can hold any one of three possible relevant values (or null). Combinations: 3^3=27 A typical combination would be round/solid/blue, or cubic/squishy/white. The task is to efficiently eliminate that part of the array if any particular {set of values} is null. That is, if I currently have no pink items, the relevant sections of the array would get eliminated. Product variations with low n-values is easy to manually handle. But with five and above, that's the math(?) theory I am trying to know the name of. (I wonder if any Matlab manuals would give a clue.) I am trying this elimination of sections of an established array instead of rebuilding the array every time a value is locked in. On the other hand, maybe I'm trying to be too smart about this and should just let the server do the grunt work over and over.
  2. Hello, I am using a component for joomla 2.5 but i hit snag where it comes to selecting the categories from a drop down box in the front end. I want to use the disabled element for the top category options so that they are visible but unselectable. Something like this: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_option_disabled The component uses the following code to hide certain categories of my choosing but i don't want to hide them i just want to add the HTML element "disabled" to the corresponding options: $options = JHTML::_('category.options','com_content',array('filter.published' => 1 )); require_once(JPATH_COMPONENT_SITE.DS.'config'.DS.'restrictions.php'); $myGroups = $acl->getGroupsByUser($my->id,false); foreach($myGroups as $gid) { if(isset($groupRestrictions[$gid])) { foreach($options as $k=>$option) { if(in_array( $option->value, $groupRestrictions[$gid] )) { unset($options[$k]); } } } } $opt = array('value'=>0,'text'=>JText::_('JOPTION_SELECT_CATEGORY')); array_unshift($options,$opt); return JHTML::_('select.genericlist',$options,'catid',"class='inputbox'",'value','text',$categoryId); } Any help is gratefully appreciated.
