Liferay Important Code Snippets

Get Theme display object

<portlet:defineObjects />

<liferay-theme:defineObjects/>

<%=themeDisplay%>

Get PortletDisplay Object

themeDisplay.getPortletDisplay()

PortletConfigurationUrl

themeDisplay.getPortletDisplay().getURLConfiguration()

RenderURL creation

<portlet:renderURL var="configurationURL" windowState="pop_up">

<portlet:param name="struts_action" value="/portlet_configuration/edit_configuration"></portlet:param>

</portlet:renderURL>

=====================

<portlet:renderURL var="sendEmailURL" windowState="<%= LiferayWindowState.EXCLUSIVE.toString() %>">

<portlet:param name="jspPage" value="/html/adminfeedbackportlet/mailsent.jsp"/>

</portlet:renderURL>

Use back url in JSP Pages:

<liferay-ui:header

backURL="<%= backURL %>"

title='<%= (organization == null) ? "new-organization" : organization.getName() %>'

PropsValues class

public static final String[] ORGANIZATIONS_FORM_ADD_MAIN = PropsUtil.getArray(PropsKeys.ORGANIZATIONS_FORM_ADD_MAIN);

String[] mainSections = PropsValues.ORGANIZATIONS_FORM_ADD_MAIN;

String[] identificationSections = PropsValues.ORGANIZATIONS_FORM_ADD_IDENTIFICATION;

String[] miscellaneousSections = PropsValues.ORGANIZATIONS_FORM_ADD_MISCELLANEOUS;

Combine Multiple Arrays

String[] allSections = ArrayUtil.append(mainSections, ArrayUtil.append(identificationSections, miscellaneousSections));

Prevent Default Success Messages in Jsp Pages After Action performed.

Write this in portlet.xml file

<init-param>

<name>add-process-action-success-action</name>

<value>false</value>

</init-param>

Get ThemeDisplay Object in Action Class

ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);

Form Submission through js and dynamic URL

submitForm(document.<portlet:namespace />fm, "<portlet:actionURL><portlet:param name="struts_action" value="/enterprise_admin/edit_organization" /></portlet:actionURL>");

Get Original HttpRequest in lifaray action class

PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(actionRequest))

Get Search Container IteratorURL

searchContainer.getIteratorURL();

If you want to change to logic say for just one action you can override the method

protected void addSuccessMessage(

ActionRequest actionRequest, ActionResponse actionResponse) {

if (!addProcessActionSuccessMessage) {

return; }

String successMessage = ParamUtil.getString(

actionRequest, "successMessage");

SessionMessages.add(actionRequest, "request_processed", successMessage); }

Find organization and community

ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);

long orgnizationId=0;

com.liferay.portal.model.Group currentGroup = themeDisplay.getLayout().getGroup();

if (currentGroup.isOrganization()){

orgnizationId = currentGroup.getClassPK();

} else if (currentGroup.isCommunity() {

orgnizationId = currentGroup.getGroupId();}}

Gets Session Messages

<c:if test='<%= SessionMessages.contains(renderRequest.getPortletSession(),"lore-request-added-successfully")%>'>

<liferay-ui:success key="lore-request-added-successfully" message="lore-request-added-successfully" />

</c:if>

AUI.IO.Request for Action URL

The Following code in Entity ModelImpl class. If we set these properties in properties file then we can enable or disable cache for particular entity. This cache applicable foe Entity and Finder cache. By default it is true.

Following is we can write in property files.

value.object.entity.cache.enabled.YOUR ENTITY MODEL CLASS NAME WITH FULLY QUAKIFIED NAME=true/false

value.object.finder.cache.enabled.YOUR ENTITY MODEL CLASS NAME WITH FULLY QUAKIFIED NAME=true/false

lock.expiration.time.YOUR ENTITY MODEL CLASS NAME WITH FULLY QUAKIFIED NAME= its Number

public static final boolean ENTITY_CACHE_ENABLED = GetterUtil.getBoolean(com.liferay.util.service.ServiceProps.get(
"value.object.entity.cache.enabled.com.vidyayug.global.model.ApplicationParamGroup"),true);

public static final boolean FINDER_CACHE_ENABLED = GetterUtil.getBoolean(com.liferay.util.service.ServiceProps.get(
"value.object.finder.cache.enabled.com.vidyayug.global.model.ApplicationParamGroup"),true);

public static final long LOCK_EXPIRATION_TIME = GetterUtil.getLong(com.liferay.util.service.ServiceProps.get( "lock.expiration.time.com.vidyayug.global.model.ApplicationParamGroup"));

Load Portal class and Portlet Classes

PortalClassLoaderUtil.getClassLoader().loadClass("com.liferay.portal.model.impl.UserImpl")

Ex:

query.addEntity("User_", PortalClassLoaderUtil.getClassLoader().loadClass("com.liferay.portal.model.impl.UserImpl"));

ClassLoader classLoader = (ClassLoader)PortletBeanLocatorUtil.locate(ClpSerializer.SERVLET_CONTEXT_NAME,
"portletClassLoader");

classLoader. loadClass("your portlet class name with fully qualified name");

Ex: query.addEntity("feedBack", classLoader.loadClass("com.vidyayug.global.model.impl.ApplicationParamGroupImpl"));

Get the Portlet level session Factory object.

private static SessionFactory sessionFactory = (SessionFactory)PortalBeanLocatorUtil.locate("liferaySessionFactory");

session = sessionFactory.openSession();

Print log messages in console:

private static Log _log = LogFactoryUtil.getLog(UniversalCommunicationAction.class);

_log.error("Number format exception whhile paring selected criteri id Cerittin Id migh not be expected value");

_log.info("this is json object====="+criteriaControlIdObject);

JQGrid:

jQuery('#list3').jqGrid('getGridParam','datatype')

jQuery('#list3').jqGrid('setGridParam',{page:1}).trigger('reloadGrid');

jQuery("#list3").jqGrid("clearGridData");

jQuery('#list3').jqGrid('getGridParam','reccount')

jQuery("#gridWrapper").hide();

var allrowssel_ids = grid.jqGrid('getGridParam', 'selarrrow');

var single row = jQuery("#list3").jqGrid('getGridParam','selrow');

var myCellData = grid.jqGrid('getCell', sel_ids[0], 'userId');

Get Phones List:

PhoneLocalServiceUtil.getPhones(String companyId, String className, String classPk)

Where companyId is the companyId you are using, classname is 'com.liferay.portal.model.Contact', and the classPk is the username you want.

This should return you a list of com.liferay.portal.model.Phone objects.

Check Method on Process Action This URL can only be invoked using POST

protected boolean isCheckMethodOnProcessAction() {

return _CHECK_METHOD_ON_PROCESS_ACTION;

}

private static final boolean _CHECK_METHOD_ON_PROCESS_ACTION = false;

Instance Factory is class creating instances for classes which are outside the current class loader.

Get Portlet Configuration URL

themeDisplay.getPortletDisplay().getURLConfiguration()

Get Organization URL

set ($test_url = (($theme_display.getPortalURL()) + "/" + ($theme_display.getLocale()) + ("/web") + ($group.getFriendlyURL()) + ("/sitemap")))

Load class and create object

Class<?> classObj=PortalClassLoaderUtil.getClassLoader().

loadClass("com.liferay.portlet.journal.model.impl.JournalArticleImpl");

JournalArticle journalArticleObj = (JournalArticle)classObj.newInstance();

Create URL for Portlet

PortletURL portletURL = PortletURLFactoryUtil.create(request,PortletKeys.PORTLET_CONFIGURATION, plid,PortletRequest.RENDER_PHASE);

portletURL.setParameter("struts_action", "/portlet_configuration/edit_permissions");

portletURL.setParameter("redirect", PortalUtil.getCurrentURL(request));

portletURL.setParameter("returnToFullPageURL",PortalUtil.getCurrentURL(request));

portletURL.setParameter("portletResource", "onceclicksite_WAR_OneclickSiteportlet");

portletURL.setParameter("resourcePrimKey", PortletPermissionUtil.getPrimaryKey(10296,"onceclicksite_WAR_OneclickSiteportlet"));

portletURL.setWindowState(LiferayWindowState.POP_UP);

portletURL.setPortletMode(PortletMode.VIEW);

Get Portlet List in Layout

LayoutTypePortlet layoutTypePortlet1 = (LayoutTypePortlet)layoutObject.getLayoutType();

List<Portlet> portletList = layoutTypePortlet.getPortlets();

AUI Pop UP window

AUI().use('aui-dialog', 'aui-io', 'event', 'event-custom', function(A) {

var smsDialog = new A.Dialog({ title: 'Site Preview', centered: true, draggable: true,

modal: true, width:600, height:400}).plug(A.Plugin.IO, {uri:url,data:{ }}).render();

smsDialog.show();});

JQuery On Click Function

jQuery('#<portlet:namespace />publicLayoutSetPrototypeId').change(function(){

alert("this is meera");

});

Jquery Selected option value

var optioVal=jQuery('#<portlet:namespace />publicLayoutSetPrototypeId option:selected').val();

alert(jQuery(this).val());

alert(optioVal);

});

Jquery get Css property values

jQuery('#theid').css('display')

Jquery Add Css property values

jQuery('#theid').css('display','none')

Jquery Add dynamic options

jQuery('#<portlet:namespace />siteDefaultRoles ').append( new Option(text,msg[0].val));

jQuery('#<portlet:namespace />siteDefaultRoles ').append('<option value="'+msg[k].categoryId+'" selected="selected">'+msg[k].categoryName+'</option>');

Jquery Bind events to element.

jQuery('[selector="site-cutome-role-name"]').bind('keypress keydown keyup', function(){

alert("this is in textt bxa key uppp");

jQuery('[selector="site-default-user-name"]').each(function() {

});});

jQuery("#siteCustomeRoles").find(".aui-field-input-text").attr("placeholder", msg[k].categoryName);

jQuery after method

add element after sleelcted object

jQuery("#siteCustomeRoles").after(currentRow.html());

Creating Portlet URLs(renderURL/actionURL/resourceURL) in Liferay through jsp and javascript

Here I am creating renderURL only.Other URL's can be created in the similar way

In JSP :

<portlet:renderURL var="renderURL ">

<portlet:param name="param-name" value="param-value" />

</portlet:renderURL>

PortletURL renderURL = renderResponse.createRenderURL();

renderURL.setParameter("param-name", "param-value");

In the above example param-name could be "jspPage" and param-value could be "/html/edit.jsp" if you want to navigate from current jsp page to some other jsp page (in this case edit.jsp) . We can set other parameters also as per our requirements.

Inside your java script :

function createRenderURL() {

AUI().ready('liferay-portlet-url', function(A) {

var renderURL = Liferay.PortletURL.createRenderURL();

renderURL .setParameter("param-name","param-value");

renderURL .setPortletId("your-unique-portlet-id");

// i.e. your-unique-portlet-id can be like "helloworld_WAR_helloworldportlet"

});

}

</script>

Note: Key point here is to set PortletId which is mandatory or else it would not be able to recognize the correct URL.

Playing with portletURL in Liferay

Without tld :

1.To get currentURL :

PortletURL url = PortletURLUtil.getCurrent(renderRequest, mimeResponse or renderResponse)

2. To make clone of a URL:

PortletURL url = PortletURLUtil.clone(portletURL, mimeResponse or renderResponse)

3. Creating PortletURL from action Response:

PortletURL renderURL = ((ActionResponseImpl) actionResponse).createRenderURL();

4. Creating PortletURL from render Response:

a.For RenderURL:

PortletURL renderURL = renderResponse.createRenderURL();

b.For actionURL:

PortletURL actionURL = renderResponse.createActionURL();

5. Using TLD's in Life ray :

<portlet:renderURL windowState="<%= WindowState.ur_state.toString() %>">

<portlet:param name="param_name" value="param_value" />

</portlet:renderURL>

<portlet:actionURL windowState="<%= WindowState.ur_state.toString() %>">

<portlet:param name="param_name" value="param_value" />

</portlet:actionURL>

If you put the *-service.jar inside the tomcat/lib/ext then you should remove it from your custom-portlet's WEB-INF/lib/.

I would suggest using the following property in your liferay-plugin-package.properties in all other portlets which use the services of MyCommon-portlet:

required-deployment-contexts=MyCommon-portlet

Only put the *-service.jar inside the tomcat/lib/ext when you need that your *-service.jar's method should be available to even the Hooks or EXTs you would create. For custom plugin portlets the liferay-plugin-package.properties should suffice.
