Remove the Categories’ items from the menu in WordPress

By default, WordPress displays the categories in the menu bar. If you don’t want them, you can’t just remove all the categories. At least one category should be present. And a post has to be categorized.

The solution is to hide the categories’ items of the menu bar with the following steps :

  • go to your WordPress dashboard
  • in the left menu, go to Appearance> Theme Options
  • expand the Navigation panel
  • check Hide all categories
  • save changes

Now your categories does not appear anymore in the menu.

Request parameters from a portlet in eXo/GateIn

Portlet specs does not provide a standard way to read a parameter from the request within a portlet, for example to get the myparameter parameter in http://localhost/portal?myparameter=myvalue.

request.getParameter() within a portlet does not help since the request object is a PortletRequest, not the HttpRequest.

An easy solution in eXo/GateIn is to use the getRealRequest method of the concrete implementation of PortletRequest of GateIn. So, in order to retrieve the myparameter param from the request in the render phase, you can do :

((org.gatein.pc.portlet.impl.jsr168.api.RenderRequestImpl) request).getRealRequest().getParameter("myparameter")
