Hi team,

I am totally new in SFDC Development and I have a big issue .
The previous Developer in my company has gone and I don't manage to resolve the redirection myself.
I would be fully grateful if someone could correct this code.

The problem of my users is the following :

" When I create a New task ,I fill in the datas in the form and I click on the save button on New Event page , I would like to be redirected to the Current view task page (URL + task id)
instead of to be redirected to the Account page ."

I don't know anything about coding in Apex so I really need your help...

I have currently a Visualoforce page nammed : TaskRedirect with this code :

<apex:page standardController="Task" extensions="TaskRedirectController" action="{!redirect}">
</apex:page>
            
It is display for a New Task, and below you will find the code of the Apex Class that is called, could you tell me what I should write to be redirect to the URL + Task_id after save??


public with sharing class TaskRedirectController {
    public final Task task;
    public User userData;
    
    public TaskRedirectController(ApexPages.StandardController redirectController)
    { 
        //get the current record
        this.task=(Task)redirectController.getRecord();
        userData = [SELECT Business_Group__c, Business_Unit__c, User_Division__c, User_Subdivision__c FROM User WHERE Id = :UserInfo.getUserId()]; 
    }
    public PageReference redirect(){
        String what_id = ApexPages.currentPage().getParameters().get('what_id');
        String who_id = ApexPages.currentPage().getParameters().get('who_id');
        String Record_Type = ApexPages.currentPage().getParameters().get('RecordType');
        String task_Id = ApexPages.currentPage().getParameters().get('Id');
        String accid = ApexPages.currentPage().getParameters().get('AccountId');
   
       if(accid == null)
           accid ='';
       if(what_id == null)
           what_id = '';
       if (who_id == null)
           who_id = '';
       if (task_id == null)
           task_id = '';
                 
 String str='/00T/e?retURL=%2F001%2Fo&nooverride=1&00N20000001kXCH='+replaceStr(userData.Business_Group__c)+'&00N20000001kXCL='+replaceStr(userData.Business_Unit__c)+'&00N20000001kXCR='+replaceStr(userData.User_Subdivision__c)+'&00N20000001kXCQ='+replaceStr(userData.User_Division__c)+'&what_id='+ what_id +'&who_id='+ who_id;      
      

        PageReference r= new PageReference(str);
        r.setRedirect(true);
        return r;
        
        }
    public String replaceStr(String s){
        if(s==null) s='';
        return s.replace('&', '%26');
    }
    
    public static testMethod void test()
    {
        Task t = new Task();
        Apexpages.Standardcontroller stdController = new Apexpages.Standardcontroller(t);
        TaskRedirectController testClass = new TaskRedirectController(stdController);
        System.assert(testClass.redirect() != null);
        System.assert(testClass.replaceStr(null) != null);
        System.assert(testClass.replaceStr('&') == '%26');
    }    
}


Many thanks for your help.
