Here’s a sample code example for a Visualforce page with a standard controller and multiple controller extensions in Apex:
Visualforce Page (samplePage.page):
Welcome to the Sample Page
Controller (SampleController.cls):
public class SampleController {
public String accountName { get; set; }
public SampleController() {
// Initialization logic
accountName = 'ABC Company';
}
}
Controller Extension 1 (SampleExtension1.cls):
public class SampleExtension1 {
private ApexPages.StandardController stdController;
public SampleExtension1(ApexPages.StandardController controller) {
stdController = controller;
}
public String getAccountName() {
// Accessing the standard controller's record
Account acc = (Account)stdController.getRecord();
return acc.Name;
}
}
Controller Extension 2 (SampleExtension2.cls):
public class SampleExtension2 {
private ApexPages.StandardController stdController;
public SampleExtension2(ApexPages.StandardController controller) {
stdController = controller;
}
public String getContactName() {
// Accessing the standard controller's record
Contact con = (Contact)stdController.getRecord();
return con.Name;
}
}
