[TYPO3-project-formidable] Number of Results (renderlet:LISTER)

Fri Feb 29 10:56:43 CET 2008

Hy again,

There is another way to get the number of filtered results from a lister.

So, you can use something like this:

	<renderlet:BOX name="filterresults" mode="inline">
		<html>
			<userobj>
				<php><![CDATA[/*<?php*/

					return $this->aORenderlets["mylister"]->aPager["numrows"];

				/*?>*/]]></php>
			</userobj>
		</html>
	</renderlet:BOX>

It is very important to put this renderlet after the definition of your 
renderlet:LISTER, so you can already access his properties. So I moved 
all the renderlet:BOX at the end of the document.

You can see the new code at:
	XML:	http://pastebin.com/f4da03d38
	HTML:	http://pastebin.com/f6479d29c

Now, I’m wondering why you couldn’t use the code line 
{mylister.pager.numrows} into your template file. Maybe, you don’t have 
the latest version of formidable? Which version do you have? If you want 
to get the latest version of formidable, please visit 
http://www.ameos.com/formidable (SVN builds -> Revision 162 to 164)

Good luck!
