Overriding a view with views_pre_render. How to be more specific?
You should be able to put in logic like

if ($view-&gt;name == 'topic_page' &amp;&amp; $view-&gt;current_display == 'MACHINENAMEOFBLOCKDISPLAY') {
  // do whatever you want whenever Views is crafting up this view and display
}


which will further filter to a specific View as well as display.
