How to get URL parameter at JSP and put it to hidden input using Liferay 7

Question

I want to get parameter from URL and set it as value to hidden input. I tried it like I did when I used Servlet API. It doesn't work. (value=0). Also I checked this answer. And nothing helped. Also I tried to use scriptlets <input type="hidden" name="views" value="<%PortalUtil.getOriginalServletRequest(request).getParameter("views").toString();%>">

But it doesn't work too. How to extract it in liferay7 portlet and set to input?

Can you print `String view = request.getParameter("views")`and check whether you are getting the value? — soorapadman, Jun 14 '17 at 10:09

HttpServletRequest httpReq = PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(renderRequest));
String abc = httpReq.getParameter("abc");

You can try to use ParamUtil. Hope this will help.

String myUserName = ParamUtil.getString(request, "views");

You should create renderURL with your parameter, smth like that:

<portlet:renderURL var="anyNameYouWantUrl" copyCurrentRenderParameters="true"> <portlet:param name="anyName" value="anyValue"/> </portlet:renderURL>

--

copyCurrentRenderParameters="true" will save your render parameter and you can easily set it to hidden input using action method.
