We are using Liferay 6.2.10 EE.
I have created a custom action referencing doc.
As part of the implementation, I read a parameter from the request (an articleId) and redirect to the appropriate web content article.
My url looks like: /c/portal/solution
This works!
My requirement is to have friendlyUrls like:: /c/portal/solution/123456
I know we have achieve this by custom portlet, as discussed here: Dynamic URLs for a Liferay Portlet
Is there a way to implement this with hooks?
I could not get any reference and I could not find any element like "friendly-url-routes" in liferay-hook.xml.
I asked this question on liferay forum too just in case their is some documentation for this:
https://web.liferay.com/community/forums/-/message_boards/message/75378827
Thanks!

I've build a custom form which action redirects to a confirm page. In the controller of this page I get the POST values via $request->request->get('fieldName');
To enhance the user experience I'd like to stay on the same page as the form and add a success message to the page. I guess this can be done via AJAX? I tried to follow this guide since it kind of seems to describe what I'm trying to achieve, but I struggle to understand the custom component part. It seems this is only for the backend?
Any help would be appreciated.
The guide you shared is about the administration, if you want to add your functionality to the storefront instead you should be able to follow this guide.
For an overview of how the administration and storefront differs, you can read up the concepts behind those two areas here.
I want to serve some data from an static url in Liferay. For example, say to serve a json containing the logged user from "http://server.com/whatever/user" so all the portlets in the proyect can read it. Right now I can do it with a portlet, but then I have to set the url with the configuration panel and I don't like that.
I've seen that I can put jsp files with the static content, but don't know how to access the information of session, users, etc.
Friendly urls seem to accomplish something similar but seem overly complicated and focused in getting a short easy url, something I don't care.
So, how can I get some internal data in an static url (I don't mind if it's friendly, long or short, but always the same) so every element of a Liferay proyect can read it?
FOURTH EDIT: Another way to put it...
In my eclipse I have this tree:
/whatever-war/docroot/html/fancy-porlet/list.jsp
How do I access that jsp in a browser without having to go the Liferay panel and putting the portlet in the menus of the web?
FIFTH EDIT: I haven't had the time to research any more, but I have this in my notes...
https://server/language/c/portal/layout?p_l_id=plid
This goes straight to the portlet, sometimes. plid comes from
PortalUtil.getPlidFromPortletId(themeDisplay.getScopeGroupId(), name_of_portlet_and_war)
It's no solution for me because, it doesn't always work. Sometimes you get a numeric identifier, sometimes you get a zero. I'd bet on the name of portlet and war being incorrect so it doesn't find the portlet, but then, how do you find the new name of the portlet? Sadly, I discarded the code where the name came from, but is coming from Liferay.
SIXTH EDIT: What I want to do is to be able to call a fixed url, with some data internal to Liferay, and get information based on that data back.
There are several aspects here:
Every portlet already has access to the user through a request attribute called ThemeDisplay:
ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);
Check ThemeDisplay's interface for the various options that you have in order to get the current user's id or object.
You've asked about JSON delivery - this will need to go through Liferay and not (directly) through a JSP in your individual web application. The reason is that any request processed by Liferay will contain the user's information, but as any proper webapp, it's completely separate from any request directed at another webapp: Unless included by Liferay, your JSP will have a different session that has nothing to do with Liferay's session. (I hope this explanation makes sense)
If you write a servletFilter hook, you might not yet have the portal context initialized (Liferay 6.x has been a while for me, pardon for being vague here). If you're on the portlet side, you might have to do more than you expected.
One option that you have is to embed a portlet on every page, automatically (e.g. when it's deployed, it's available). You can configure a portlet to be automatically included on every page, it's done for the chat portlet, for example. That portlet does not need to have any UI, it just needs to expose its resourceURL, so that you can use it from everywhere.
However, I somehow doubt that you use it, given that every portlet has the information already at hand.
But I might also just not understand all of your requirements...
I'm trying to figure out how to link to another page within the same liferay site.
Obviously I could hardcode the url in my portlet's view but I'm worried about having to update all of my portlets in case the friendly url changes in the future.
I know the name of the page I'm trying to link to, but what if the page name changes too?
I've found infinity of classes that have methods that return friendlyUrls, such as PortalUtil, LayoutLocalServiceUtil, and even LayoutFriendlyURLLocalServiceUtil, but they all require parameters that I'm not sure how to obtain.
Is there a standard way of obtaining friendly urls in liferay?
If you want to link to another Page, you can either use LayoutId or friendly url names.
Both are unique for each companyId, so you are going to be pretty safe using them.
You can set the friendlyUrl as a PortletConfig parameters, so you can set them on portlet Level, and you won't have them hard-coded in your Portlet. Alternatively, you can also save them as custom params in portal-ext.properties (will apply for all portlets of that portal).
Now, that's a lot of code for this, so if you're dealing with specific problems, like creating Portlet Configuration or Reading portal-ext.properties, or creating renderUrls programatically, you should start new questions
I have passed a render parameter from one portlet to another using user friendly url navigation.
response.setRenderParameter("params", renderParams);
response.sendRedirect(response.encodeURL("/wps/myportal/Home/abcPortlet"), "params");
Here Home and abcPortlet are user friendly page names for specific pages.
While debugging I found that OriginalParameterMap contains the render parameter in its URL.
Can someone tell me how to retrieve it? As usual getter methods are not able to retrieve that value.
You cannot pass render parameters from one portlet to another. It has to be Pubic Render Parameter (PRP). The approach of setting PRP is same as that of render parameter, but both portlets should agree that, they support that PRP. For that you need to register the supported PRPs in portlet.xml file of both the portlets. Please refer to this link for more info.This is what the specification insist. Imagine a scenario where in we have multiple portlets from various vendors on a portal page. It is a security concern if one portlet could retrieve the parameters from the URL even if it is not targeted to that portlet.
Another approach (which is not recommended) is to type case the RenderRequest to HttpServletRequest and get the parameter from request. It is not mentioned in the specification that PortletRequest should be a HttpServletRequest. So it is better not to do that. Future implementation of Portal can change this.
Third approach is to use the URL Generation APIs and construct the URL which has the parameters targeting the portlet. You can refer to the below link which has some helper classes. This will simplify your job. Advanced URL Generation Helper Classes
The best way is to use PRP. Both the source portlet and target portlet are loosely coupled.
I am using Liferay 6 for development .
I have developed a Custom Login Portlet using Struts2 .
I am able to display my Custom Login page , On click of the Submit Button after validating the credentials aganist our MYSQL Databse , please tell me how can i display my 4 other Custom Portlets on entering valid credentials ??
please guide me what is the concept i should refer for this in liferay
( I am using Liferay 6 for development )
Okay, the way I would suggest you do this is by:
adding the 4 other portlets to your Custom Login page (or add a redirect on successful login, and them to the page you redirect to)
Set the permissions of your Custom Portlets to be viewable by only authenticated users. This can be done by removing Guest "View" permissions. This way a non-authenticated user or "Guest" won't see your portlets when the go to the page.
Does this answer your question?
~~ EDIT IN RESPONSE TO COMMENT ~~
Okay, so if you're using Struts, instead of redirecting to a JSP file, you want to redirect to a URL instead. So instead of /view/result.jsp it should be something like http://yoursite.com/page_with_4_portlets_on_it or just a relative URL /page_with_4_portlets_on_it (if the two pages are on the same Navigation level.
HOWEVER:
If you're new to Liferay then I would strongly suggest you use Liferay's inbuilt Portlet architecture using their MVCPortlet class. This will handle all the mappings, and workings that you have to manually write for using Struts. Then you can implement a doPost() method and do a ActionResponse.sendRedirect("/page_with_4_portlets_on_it");
Then this means that when your form action completes Liferay will redirect the user to the page you've specified.
The best place to get started with Liferay 6 portlets, the Liferay way is here.
