[SalesForce] Prepopulate fields on visualforce page from a button on another VF page

I have two Visualforce Pages, one for Account and another for Opportunity.
On the Account page there is a button named New Opportunity. I want to pre-populate some data from Account fields to the Opportunity page.

What I have done so far is I have created a button with the following url:

/apex/Oppurtunitynew?retURL=%2Fapex%2Faccountview%3Fid%3D{!Account.Id}%26sfdc.override%3D1%26core.apexpages.devmode.url%3D1&OIP87654543={!account.name}accid={!Account.Id}&sfdc.override=1

When I click on this button it redirects to the Opportunity page (correct), but does not populate the fields (incorrect).

I have checked the redirecting URL which is

https://c.cs5.visual.force.com/apex/Oppurtunitynew?retURL=%2Fapex%2Faccountview%3Fid%3D%26sfdc.override%3D1%26core.apexpages.devmode.url%3D1&accid=&sfdc.override=1

What I found it is not taking account id after redirecting.

Based on the resulting url, your {!account.Id} value is null. This indicates the record has not yet been inserted. So the core problem has nothing to do with parameters, but rather order of operations. You should use a commandButton that calls an action something like:

public static final String ID_PARAM = 'Id';
public static final String ACCOUNT_PARAM = 'accid';
public static final String RETURL_PARAM = 'retURL';

public PageReference save()
{
    try
    {
        insert myAccount;
    }
    catch (DmlException dmx)
    {
        ApexPages.addMessages(dmx);
        return null;
    }

    PageReference retUrl = Page.AccountView;
    retUrl.getParameters().put(ID_PARAM, myAccount.Id);

    PageReference redirect = Page.OpportunityNew;
    redirect.getParameters().put(ACCOUNT_PARAM, myAccount.Id);
    redirect.getParameters().put(RETURL_PARAM, retUrl.getUrl());
    return redirect;
}

Note that because your parameter names are all public, you can now reference them from your other controller/extension to make sure you get an exact match. Your markup would look something like:

<apex:pageMessages id="msgs" />
<apex:form>
    <apex:commandButton value="Save" action="{!save}" rerender="msgs" />
</apex:form>

[SalesForce] URL hacking on a VisualForce page

The related list will already pass parameters from the standard button, so there is no need URL hack, you just need to know the parameter (which you would be using for URL hacking anyways) Then you assign the value to the record generated by the controller. Here is a an extremely simplified example.

Controller

public class OppEntryTestExtension {

  public OppEntryTestExtension(ApexPages.StandardController controller) {

    // Get Parameters that correspond to those passed by related list
    Id accountId = ApexPages.currentPage().getParameters().get('accid');

    // Reference to Controller Record
    Opportunity opp = (Opportunity)controller.getRecord();

    // Assign values to Record
    opp.AccountId = accountId;

  }

}

Visualforce Page

<apex:page standardController="Opportunity" extensions="OppEntryTestExtension">

   <apex:form>
     <apex:inputField value="{!Opportunity.AccountId}" />
   </apex:form>

</apex:page>

In this example we override the standard Opportunity New page and use the parameter passed by the Opportunity related list on the account to set the Account on the Opportunity.

Once you have the id of the incoming object, you could also query that object if there were other fields you wanted to pre-populate in your new related object. (for example, I wanted to use an Account Type field to set a type field on the Opportunity)

[SalesForce] How to pass parameter in the new button to VF page in related list section

Visualforce interprets fields like into the underlying SObject. That means that you can reliably determine the parent record like this:

public MyController(ApexPages.StandardController ctrl) {
    MySObject__c record = (MySObject__c)ctrl.getRecord();
    Id parentId = record.ParentField__c;
    // Do something with parentId
}

You should never rely on ApexPages.currentPage().getParameters() for values like "Id" or a specific field name, because they could theoretically change at any time. Always use supported methods, like StandardController.getRecord(), to get fields that are passed in to the Visualforce page via the system.
