Hide and disable access to Liferay's 6.1 control panel.

It is often needed to hide control panel dockbar for simple users. This article I'll describe different ways to achieve this.

 First we need to change theme little in order to hide dockbar, it can be done in following way.

Create new theme if you don't have theme ready.
In portal_normal.vm file, change following lines of code

#if ($is_signed_in)
#dockbar()
#end

 in to following.

#if (($is_signed_in) && $permissionChecker.isCompanyAdmin($company_id))
 #dockbar()
#end

It will remove dockbar for all non admin users.

 But user still can be able to access control panel by typing the following url 

 http://localhost:8080/group/control_panel.

 To avoid this, we can write costume hook to restrict user to doing so.

 Let's check how this can be done:

 In liferay-hook.xml add following lines of code.

 <portal-properties>portal.properties</portal-properties>

Add portal.properties file to hook's src folder and add following line to it.

 servlet.service.events.pre=my.event.portal.ControlPanelAccessPreAction

Create ControlPanelAccessPreAction.java in appropriate package and add following code.

 package my.event.portal;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.liferay.portal.kernel.events.Action;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.util.WebKeys;
import com.liferay.portal.model.User;
import com.liferay.portal.security.auth.PrincipalException;
import com.liferay.portal.service.GroupLocalServiceUtil;
import com.liferay.portal.service.RoleServiceUtil;
import com.liferay.portal.service.UserServiceUtil;
import com.liferay.portal.theme.ThemeDisplay;

/**
 * The ControlPanelAccessPreAction restricts access to Control panel of simple
 * users.
 */
public class ControlPanelAccessPreAction extends Action {

  /**
   * Instantiates a new control panel access pre action.
   */
  public ControlPanelAccessPreAction() {
 super();
  }

  /*
   * @see com.liferay.portal.kernel.events.Action#run(javax.servlet.http. HttpServletRequest,
   * javax.servlet.http.HttpServletResponse)
   */
  public void run(HttpServletRequest request,
      HttpServletResponse response) throws ActionException {
 try {

   ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);
   if (GroupLocalServiceUtil.getGroup(themeDisplay.getLayout().getGroupId()).isControlPanel()) {

  User currentUser = UserServiceUtil.getUserById(themeDisplay.getUserId());
  if (!RoleServiceUtil.hasUserRole(currentUser.getUserId(),
           currentUser.getCompanyId(),
           "administrator",
           true)) {
    throw new PrincipalException("User " + request.getRemoteUser()
     + " can't access the control panel.");
  }
   
   }
 } catch (Exception ex) {
   throw new ActionException(ex);
 }
  }

}

 Deploy the hook.
That's it, now you completely hide and restricted access to control panel.

The Simplest Way To Center Elements Vertically And Horizontally

Flexbox is a relatively new addition to the CSS world and we keep finding more and more excellent applications for it. We can even solve the age-old problem with centering an element both vertically and horizontally with CSS. It is easier than you can imagine – it is only three lines of code, doesn’t require you to specify the size of the centered element and is responsive-friendly! This technique works in all modern browsers – IE10+, Chrome, Firefox and Safari (with the -webkit- prefix). See the full compatibility table here . The HTML The idea, of course, revolves around flexbox. First, we create a container in which we want everything to be centered: <div class="container"> <h3> All content in here will be centered. </h3> </div> You can place this container div anywhere you want. In the live example above we’ve made it take up the whole width and height of the page. The CSS As we said earlier, we will be u
