How can I take parameters from one page to another with different controllers in Salesforce?

Hi,

You can use the below code snippet for this

public Pagereference gotonewpage()
{
PageReference pageRef = Page.existingPageName;
pageRef.getParameters().put('msg','success');
return PageRef
}

This will make your URL looks like this //na5.salesforce.com/apex/SamplePage2?msg=success

Retrieve Parameter Values in Apex Class:

public class Sampleclass
{
Public String message = System.currentPagereference().getParameters().get('msg');
}

Hope this helps you.

Hi,

In the code segment below we are passing two parameters along the page url – ownerid and eventid :

PageReference newPage =
new PageReference('/apex/cys_meeting_rooms?ownerid='+event.OwnerId+'&eventid='+event.Id);
return newPage.setRedirect(true);
Now here is how to get these values on second VF page :

In salesforce we can get parameter values from the current page url by using global variable $CurrentPage. We can use CurrentPage.parameters.parameterName to reference page request parameters and values, where parameterName is the request parameter being referenced.

For the page url invoked above, we can display the value of eventid parameter in the page url on our VF page as :

<apex:outputText value="{!$CurrentPage.parameters.eventid}">
It will display the values of the page parameter eventId as output text on the VF page.

Hope this helps.
