Synchronize 2 Getresources Calls

I am making 2 getresources calls to generate galleries(li and img tags) that are interactive with each other. I would like to limit and randomize each of them, but need to make sure that the same 5 resources get returned in each one. Any ideas?

One way might be to write a snippet that produces a random number based on the number of images - 5 and writes that value to a TV.

Call the snippet uncached once at the top of the page, then use the TV value in the &offset property of getResources. The images will be in order from the offset value -- I don't think you can randomize the 5, but they'll be taken from a random part of the table.

Another way, if it would work for you, would be to use the &toPlaceholder property to have the results written to a placeholder, then use that placeholder in both places.

Bob, thanks for the thought starter... I ended up putting my 2 getresources calls in a snippet and then passed a simple php variable with the 3 pre-generated random id numbers...

Outer call from template:
[[!randomauthorgenerator? &rset=`[[!getResources? &parents=`99` &limit=`3` &sortby=`rand()` &tpl=`@INLINE [[+id]],`]]`]]

Inside the snippet:

<?php
echo '
<div id="auther-slider-thumb" class="auther-slider-thumb">


[[!getResources? &resources=`'.$rset.'` &limit=`3` &includeContent=`1` &includeTVs=`1` &processTVs=`1` &tvPrefix=`` &tpl=`AuthorImg`]]


</div>
<ul class="auther-slider">
[[!getResources? &resources=`'.$rset.'` &limit=`3` &includeContent=`1` &includeTVs=`1` &processTVs=`1` &tvPrefix=`` &tpl=`AuthorDetail`]]

</ul>
';

I'm glad you got it sorted.

You might consider turning things around by getting the resource list inside the snippet without the overhead of another getResources call (untested).
