Redirect from VF page to Add Products page

Question

I have written a visualforce page with a button and i want that when it's pressed there is a redirect to the standard page ADD PRODUCT!(the page that is opened when you click OPPORTUNITY--->ADD PRODUCT)

The URL is salesforce.com/p/opp/SelectSearch?addTo=006E000000AVjws&retURL=%2F006E000000AVjws

I have written the following code but it doesn't work:

<apex:form >
    <apex:commandButton value="Add Product" action="{!addProduct}">
    </apex:commandButton>
</apex:form>

public class tempsection {

public PageReference addProduct(){

Id conids='006E000000AVjwsIAD';

String newPageUrl = '/p/opp/SelectSearch?addTo='+conids;

PageReference p = new PageReference(newPageUrl);
p.setRedirect(true);
return p;
}

}  

Is the Opportunity ID the only necessary?

Thank you in advance for any advice.

Answer 1

Is the Opportunity Id available from the VF page context? If so, you could save yourself some Apex code and do this:

<apex:form >
    <apex:commandButton value="Add Product" action="{!URLFOR($Action. OpportunityLineItem.AddProduct,<ref to opportunity id>)}"/>    
</apex:form>

I would always go for the Action global variable above hacking the raw URL from the browser I can.

If you can't just pick up the URL from the VF page context (std controller or url param) then just have a simple controller property to retrieve the opportunity id:

<apex:form >
    <apex:commandButton value="Add Product" action="{!URLFOR($Action. OpportunityLineItem.AddProduct,OppId)}"/>
</apex:form>

-

public class tempsection {

    public string getOppId(){
        //whatever logic to get the actual opp Id
        return '006E000000AVjwsIAD';
    }

}   

And I've not tested this exact usage of the Action global variable, so I have some questions myself about how this gets the list of products in the first place. But this might send you on your way.

The best code example I've found to do this is at http://www.michaelforce.org/recipeView?id=a0G30000006eVxVEAU
