CountSubEntries
^^^^^^^^^^^^^^^

This one counts in another table. It's easier to explain with an example: You are displaying page entries and want to show the number of content elements on that page -- this is how you do that.

sDatabase
---------

String. If the database differs from dbal/sDatabase, enter it here.

sTable
------

String. Table name of the table to count in. Following our page-contentelement-example: ::

    tt_content

sTableColumn
------------

String. The other end of the relation. Connect the column/field on which this callback is performed with this sTableColumn in the foreign table (sTable) where you count in. The example would consist of the pages' *uid* column on which this callback would be performed. sTableColumn would in that case be set to ::

    pid

sWrap
-----

String. Maybe you want to show more than just the default raw number of entries. Just keep in mind to include the pipe sign (|). Example: ::

    | content elements on this page

Of course, as always, you might want to use markers here: ::

    <a href="?id=###uid###">| content elements on this page</a>
