Accessing theme images in WCM templates

[Chris Becker，修改在11 年前。]

Hi everyone;

I am using Liferay 6.1 edition in a JBoss app-server environment.

Can anyone tell me how to access images stored in a theme's image folder from within a WCM Velocity template?

I am creating a WCM template that contains a form, and I wish to use an image for the Submit button. I would like to store that button image within the theme, and just reference via a Velocity variable, or at least a Velocity variable that gives me the image directory of the theme and then just append the image name to it.

Any guidance as to how this could be done would be appreciated - thanks in advance!

Regards,

hi Chris Becker :

Try to use :
#set($theme_image_path = $request.get("theme-display").get("path-theme-images"))

Hey Ahmed;

Any chance you would have a similar approach for getting the path to Javascript files?
I tried using the approach above and just request javascript, as follows:
#set($theme_javascript_path = $request.get("theme-display").get("path-theme-javascript"))

However, this did not work. Any ideas?

hello Chris

The theme js path can be retrieved through $themeDisplay.getPathThemeRoot()js on liferay velocity but since $themeDisplay is not available on liferay CMS you cant use it and you have to use the $request.get("theme-display").get("path-theme-images") with some string manipulation like this :

#set($theme_javascript_path = $request.get("theme-display").get("path-theme-images").substring(0, $request.get("theme-display").get("path-theme-images").lastIndexOf("/images")).concat("/js"))

Wow... almost makes you think that Liferay doesn't want this to happen!


But it works, Ahmed... thanks again for your help!

Hi--

The real, actual request and themeDisplay objects (not the request and themeDisplay maps) are available in liferay cms (at least in LR 6.1.1)

#set ($serviceContext = $portal.getClass().forName("com.liferay.portal.service.ServiceContextThreadLocal").getServiceContext())
#set ($httpServletRequest = $serviceContext.getRequest())
#set ($objThemeDisplay = $httpServletRequest.getAttribute("THEME_DISPLAY"))

See the 3rd to last comment at http://www.liferay.com/web/raymond.auge/blog/-/blogs/custom-velocity-tools-and-liferay-6-0 . This is really good to know!
