working with VM variables?

[Path Finder LifeRay, modificado 11 Anos atrás.]

Hi All,

I'd like to know how to work with the velocity variables?
While trying to work with themes i have seen the templates folder, and i came to know that vm files was written in velocity mark up language.

Now my question are:

where these variables are defined, for example($nav_item,$nav_item.getURL())etc.,not specifically about nav, variables like these in the whole vm files.

how to get these variables?if i need to define new variables where i can set?

is there any documentation/tutorial available for creating the vm files?please guide me

regards
path

Variables are already available to your template files. See this wiki page for details.

One way of setting defining and using custom VM variables is:

Step 1:

Make a variable " show-control-panel " of boolean type

import com.liferay.portal.kernel.events.Action;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.util.WebKeys;
import com.liferay.portal.model.User;

public class CustomAction extends Action
{
	static Logger logger = Logger.getLogger(CustomAction.class);
	
	@Override
	public void run(HttpServletRequest request, HttpServletResponse response)
			throws ActionException {
		
		
		Map<string, object> vmVariables = new HashMap<string, object>();
		
		HttpSession session	=	request.getSession(true);
		
		if(session!=null)
		{
			User user	=	(User)	session.getAttribute("USER");
			
			if(user !=null &amp;&amp; user.getJobTitle().equalsIgnoreCase("admin"))
			{
				vmVariables.put("show-control-panel", true);
			}
			else
			{
				vmVariables.put("show-control-panel", false);
			}
			request.setAttribute(WebKeys.VM_VARIABLES, vmVariables);
		}
	}
}
</string,></string,>

Step 2:

now in theme you can access this variable with " $show-control-panel "

You can set your variables in init_custom.vm file.
