texte = a var will only equal null when assigned that value - either on purpose via form var (that includes passed in URLs), or from if you getting a db field value where that field has no text in it yet (this includes orderfile headers).If a var is unititialized (not given a value by any means, then it's value = [var].[showif [URL][var1][/URL]=[URL][raw][var1][/raw][/URL]] var1 has not been initialized (if that is the right terminology... ie var1 has not been assigned a value [/showif]If you are using the XML webcat tags and parser then an unititialized var = undefined (I think. Someone correct me if I am wrong).Always take note if the var is potentially getting its value from: 1) a db field (incl. ordefile header) , or else 2) other means like formvar, [math], [text] , etc.HTH-Johnchas wrote:> Hi > > Search Page: > > I have a search page with 2 contexts > > one displays by a product Category > > one displays by Company > > Results Page > > I have two search contexts > > one shows results of the Category selection > > one shows results of the Company selection > > They both work, but > > I want to hide/show the empty search table and its founditems. > > I have put on the results page to test..... > > category = [category] > > company= [company] > > the context I want to hide = [fieldname] either the [Company] or the [Category] - not a value > > so I have tried: > > [showif [company]=[company]] > > for the category search results > > and > > [hideif [company]!] > > to test the null and therefore hide that context. > What am I missing? > > Thanks In Advance > > Charley Conquest > > results.tpl below > > > > >
