Get Category ID from URL title of URL segment?

Question

My Url: http://somelink.com/package/view/a-hald-day-trip-to-the-zoo

//my code below... from url above i want to use entry title category id as my category id below, the url above and my code below have below to separate channels but they share categories groups//

    {exp:channel:entries 
        channel="departures" 
        category="{last_segment_category_id}" 
        limit="10" 
        dynamic="no"
    }
       <p>{title}</p> 
   {/exp:channel:entries}

//But this code above Does not work!, i tried using cat2seg but i think this works with category url and not url title//

Answer 1

{last_segment_category_id} is not a variable provided directly by ExpressionEngine. So to get this value you need to install an add-on - it is not clear from your question what add-ons you are using (or what version of EE...).

To get a value from the variable {last_segment_category_id} you will need to have installed either URL Helper addon (from here) or Low Seg2Cat (from here), both of which define this variable.

It is probably worth checking which of these you are using (or install one). I am not sure what happens to the variable if you install both add-ons...

You also could achieve something like this result using cat2 (here) but with different tag syntax.

HTH.
