How to implement “Save & New” functionality in a VisualForce Page

Question

I know that this is how to save a record

<apex:commandButton action="{!save}" value="Save"/>

Now I want a button to save the current record and reset the form to input another record.

Something like this...

<apex:commandButton action="{!SaveAndNew}" value="Save & New"/>

Answer 1

The save method can be defined such that where m_sc is a reference to the standardController which is passed to your extension in it's constructor:

public Pagereference doSaveAndNew()

  {

    SObject so = m_sc.getRecord();

    upsert so;

    string s = '/' + ('' + so.get('Id')).subString(0, 3) + '/e?';

    ApexPages.addMessage(new ApexPages.message(ApexPages.Severity.Info, s));

    return new Pagereference(s);

  }

Now since you want to your controller as an extension, you can modify it's constructor to take a StandardController reference as an argument:

public class TimeSheetExtension

{

  ApexPages.standardController m_sc = null;

  public TimeSheetExtension(ApexPages.standardController sc)

  {

    m_sc = sc;

  }

Now, you need to modify your <apex:page> tag in your page in order to reference it as an extension:

<apex:page standardController="Timesheet__c" extensions="TimeSheetExtension">

  <apex:form >

    <apex:pageMessages />

    {!Timesheet__c.Name}

    <apex:commandButton action="{!doCancel}" value="Cancel"/>

    <apex:commandButton action="{!doSaveAndNew}" value="Save & New"/>

  </apex:form>

</apex:page>
