Question

I have a force.com site with custom url for my web2lead just say www.company.com/step1. i want redirect it to www.company.com/step2 after button clicked but it redirecting to www.company.com/step1/step2.

here's my PageReference

public PageReference Next(){ 
web2lead.Name = firstName+' '+lastName;
web2lead.Phone__c = phone;
web2lead.City__c = city;
web2lead.Company__c ='Keluarga '+firstName+' '+lastName;
web2lead.Email__c = email;
insert web2lead;

web2leadId = web2lead.Id;

PageReference step2Form = new PageReference('/step2');
step2Form.getParameters().put('id',web2lead.Id);
step2Form.setRedirect(true);
return step2Form;
}

did i doing something wrong ? because i don't want to put full url to PageReference like PageReference('http://www.company.com/step2');. can i do that ?

Answer 1

You have suggested that you don't want to hard code the full URL like http://www.company.com/step2. In this case you can get the full URL dynamically with URL.getSalesforceBaseUrl().toExternalForm() and append the vf page name with it. I tried with the below solution and it is working as expected. Please try and let me know if this works.

step1 vf page

<apex:page controller="RedirectTestController"  >
    Hello World {!baseUrl}
    <apex:form>
        <apex:commandButton action="{!Next}" value="Step2"/>
    </apex:form>    
</apex:page>

step2 vf page

<apex:page >
    Hello World
</apex:page

Controller

public class RedirectTestController {
    public String baseUrl;
    public String getBaseUrl() {
        baseUrl=URL.getSalesforceBaseUrl().toExternalForm();
        return baseUrl;
    } 
    public PageReference Next(){ 
        String nextpageurl = getBaseUrl() +'/step2';
        PageReference step2Form = new PageReference(nextpageurl);
        step2Form.setRedirect(true);
        return step2Form;
    }
}

Instantiate PageReference approach Page.Page_API_Name as:

PageReference step2Form = Page.step2; // Return pagereference Page.Page_API_Name
step2Form.getParameters().put('id',web2lead.Id);
step2Form.setRedirect(true);
return step2Form;
