Overriding Save functionality

Overriding "Save" functionality when using a standard controller can be accomplished by a simple extension.

Visualforce page for inputing the data of the Testing__c object.

Custom Fields (Testing__c)

• Name
• City__c

Visualforce Page

<apex:page sidebar="false" standardController="Testing__c" extensions="OverrideSAVE">

  <apex:form >

      <apex:pageBlock >

          <apex:pageBlockSection columns="1">

              <apex:inputfield value="{!Testing__c.Name}"/>

              <apex:inputfield value="{!Testing__c.City__c}"/>

              <apex:commandButton value="SAVE" action="{!dosave}"/>

          </apex:pageBlockSection>

      </apex:pageBlock>

  </apex:form>

</apex:page>

• Contructor fetching the inputfields data and storing the same in the "CON" variable. 
• "doSave" method doing the saving of the inputted records and redirecting the page as required.

Apex Class

public with sharing class OverrideSAVE {

    ApexPages.StandardController con;

    public OverrideSAVE(ApexPages.StandardController controller) {

        con=controller;

    }

   

    public pagereference dosave(){

    con.save();

    pagereference ref=new pagereference('/apex/standardSavePage');

    ref.setredirect(true);

    return ref;

    }

}
