[Snippet] homepagedisplay #

//homepagedisplay by Mark Kaplan
//Please create a tv with a checkbox titled something like "Promote to home page". Then look up in the db which tmplvarid it is in the site_tmplvar_contentvalues table. If it is your first tv ever it will be 1. Enter this value for $tempid. Then add this snippet to your homepage and promote some documents. You are set. If you have any text in the summary field it will be displayed instead of the shortened content by default (very handy if you experience formatting issues)
