Liferay URL Parameter details

Whenever you have used liferay, you surely have seen a URL like this:


http://localhost:8080/web/guest/neu?p_p_id=23&p_p_lifecycle=0&p_p_state=maximized&p_p_col_id=column-1

In my case it´s a URL that is shown when the portlet is maximized.
In this blog post I want to show you how to interpret those URL parameters so that you have the possibility to construct one on your own.

p_p_id : 


This is the unique ID of your portlet. If you don´t know the ID, you can just maximize it. If you want to have a list of the portlet IDs, the liferay portlet provides, take a look here:


http://www.liferay.com/de/community/wiki/-/wiki/Main/Portlet+IDs

Whenever you perform an action in your portlet and you submit a form, then this is the variable that liferay uses to identify the portlet to update.

p_p_lifecycle :


This was called p_p_action before and determines whether the render() method of your portlet should be executed or a struts action. 0 means render, 1 means execute.


p_p_mode: This just tells the Struts action you executed


p_p_state:


This hoolds the state of the portlet, just like you woulkd do if you would click on the "+" and "-" buttons on the top right corner of the portlet.


Maximized: Maximizes the portlet, taking the whole width of the page. No other portlet will be shown.


Minimized: Minimizes the portlet so that it just shows it´s title:


Exclusive: Expands the portlet to thr browsers width and height. No more portal ...





If you like this post it would be very nice, if you could click on some of the google ads you see on the right side. It helps me run this block and motivates me ;)
