Hi All,
I want to toggle one link in web content display based on if user is signed-in or not. Is there a way I can check in web content display if user is signed-in?

Thanks for the reply.

This may help

You could check for the role "user" or "community member" vs. "guest".
As the web content display would be static and not respond to such dynamic behaviour, you could create two web content displays - one for the guest and one for the other users.
Somewhere (probably look&feel) you can configure that the non-authorized user would not even see the message "not authorized", so everybody would see only one web content.

Hi Jelmer,
Thanks for the reply.
However the post you mentioned is other way round i.e. checking in velocity template if user is signed in or not.
I am looking for the check - if user is signed in or not, in web content display.


Hi Hiran,
Thanks for the reply.
I dont want to hide the whole web content display rather want to hide link in that. And just for one link, I dont think its good practice to create two separate web content display.

I am not sure if i understand you then

structure + template = webcontent

The only way to do anything dynamic in webcontent is by using (velocity / xsl) templates. The post i linked explains how to check if you are logged in in a velocity template used to construct webcontent

Hi Jelmer,
Thanks for reply.
I will explain bit more about my question:

I am using liferay web content display portlet. Added using dockbar on the page. After clicking Edit web content link for that web content, I have added some links on the web content. Now I am writing javascript function in that which should check if user is signed-in or not to toggle on of the image. However, I couldnt find yet how to retrieve user details in that javascript function.

Please let me know if you need more details around it.
Again, thanks for helping me out.

Hi Rupesh,

I guess that javascript in/for web content will not work.
You have to write your own structure and template and in template you can check weather user is logged in or not using velocity variables.

Hope that might help you.

Thanks Nisarg for the reply.
Can you suggest wiki/documentation explaining how to create structure & template using web content display.

Appreciated your help.

Hi Rupesh,

You can refer below link

http://docs.liferay.com/portal/6.0/official/liferay-administrator-guide-6.0.pdf

there is section 4 for WCM..

Hope this helps.

Thanks Nisarg for the details.

We just had a similar requirement for Liferay6.
A simplified way of detecting whether the user is logged in from within the web content and doing certain action without engaging Velocity Templates mechanism is below.
Stick the following javascript at the bottom of the web content article located on a page where you want to have this action.
This particular script will redirect the user to another page in 3 seconds if user is signed in.

It assumes that you have jQuery, modify script if you do not use it. Cookie such as COMPANY_ID is set by the portal for any signed in user.
Why 3 seconds delay? In case you want to modify the page while you are signed in. It will give enough time to click on X button to stop javascript running.


In case when in your version of portal COMPANY_ID cookie is not being set, you can use run-time detection of some content on the page, e.g. if Sign In portlet (portlet_58) displays the message "You are signed in as...";
