Hi,

I have a requirement to enter input fields on one Visualforce page and show the output of the same field on another visual force page.

below are my Visualforce page code and apex code.

Visualforce page 1:

<apex:page standardController="Vendors_Detail__c" extensions="Vendorhandler" id="page" >
        <!-- Javascript -->
    <script type="text/javascript">
    
    function nameValidation(id)
    {
         if(id == 'page:form:pb:pdf'){
        this.clickMe();
        }
         if(id == 'page:form:pb:save'){
        this.amtValidation();
        }
        
        var n = document.getElementById('{!$Component.page.form.pb.pbs.name}');
        var a = document.getElementById('{!$Component.page.form.pb.pbs.amtevent}');
         var c = document.getElementById('{!$Component.page.form.pb.pbs.city}');
        var b = document.getElementById('{!$Component.page.form.pb.pbs.country}');
        
        if(n.value == "")
        {
            alert("Name is mandatory");
            return false;
        }
        else if (a.value == ""){
            amtValidation();
            return false;
            }
            else if (b.value == "" || c.value == ""){
            clickMe();
            return false;
            }
                 
        }
    
  function amtValidation()
    {
        var a = document.getElementById('{!$Component.page.form.pb.pbs.amtevent}');
        var savebtn = document.querySelector("[id$='save']");
        
        if(a.value == "" )
        {
            alert("Enter Amount to show Send Email Button");
            savebtn.style.visibility = 'hidden';
            return false;
        }
        else
        {
            save();   
        }
        }
    
function clickMe()
     {
        var a = document.getElementById('{!$Component.page.form.pb.pbs.city}');
        var b = document.getElementById('{!$Component.page.form.pb.pbs.country}');
        var pdfbtn = document.querySelector("[id$='pdf']");
        
        if(a.value == "" )
        {
            alert("Enter state to show Generate Pdf Button");
            pdfbtn.style.visibility = 'hidden';
            return false;
          
        }
        else if(b.value == "")
        {
            alert("Enter Country to show Generate Pdf Button");
            pdfbtn.style.visibility = 'hidden';
            return false;
       
        }
        else
        {
            clickme();
        }
    }
   
    </script>
<!-- Javascript -->
    
    <apex:form id="form">

        </apex:outputPanel>
        
     </apex:pageBlock>
    </apex:form>
   
</apex:page>

Apex Code:

public with sharing class Vendorhandler {
    public Vendors_Detail__c vendor {get; set;}
    
    public Vendorhandler(ApexPages.StandardController std) {
        vendor = (Vendors_Detail__c) std.getRecord();
    }   

    public PageReference save(){
        
        insert vendor;
        
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        String[] toAddresses = new String[] {'sasanjayt@gmail.com'};
        mail.setToAddresses(toAddresses);
        String emailSub = 'Vendor Registration Details';
                mail.setSubject(emailSub);
        String content = 'Vendor Company name = ' + vendor.Vendor_Company_Name__c + ',<br/><br/>'+ 
                              ' Vendor Contact person = ' + vendor.Vendor_Contact_Person__c + ',<br/><br/>' + 
                              'Amount per Event = ' + vendor.Amount_Per_Event__c + ',<br/><br/>' + 
                              'City = '+ vendor.City__c + ',<br/><br/>'+
                              'Country = '+ vendor.Country__c + '.<br/><br/>'+
                              '<br/><br/>Thank you <br/><br/>';
        mail.setHtmlBody(content);
        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
       
        return null;
        
    }
    public PageReference reset() {
        PageReference newpage = new PageReference(System.currentPageReference().getURL());
        newpage.getParameters().clear();
        newpage.setRedirect(true);
        return newpage;
    }
    
     public PageReference clickme(){
         insert vendor;
         PageReference newpage = Page.Vendor_Regidtration_form_pdf;
         newpage.setRedirect(true);
        //Vendors_Detail__c v = new Vendors_Detail__c();
        // v.Vendor_Company_Name__c = vendor.Vendor_Company_Name__c;
         //v.Vendor_Contact_Person__c = vendor.Vendor_Contact_Person__c;
         //v.Amount_Per_Event__c = vendor.Amount_Per_Event__c;
         //v.City__c = vendor.City__c;
         //v.Country__c = vendor.Country__c;
         return newpage;
         
         
    }
    
}

VisualFrce page 2:

<apex:page standardController="Vendors_Detail__c" extensions="Vendorhandler" renderAs="PDF">
    <apex:form>
        <apex:pageBlock title="Vendor Registration Form" >
            <apex:pageBlockSection>
                <apex:outputField value="{!vendor.Vendor_Company_Name__c}" label="Vendor Company Name"/>
            </apex:pageBlockSection>
 
        </apex:pageBlock>
    </apex:form>
</apex:page>

Kindly help me in accessing the values of input fields of page 1 to output field of page 2.

Thanks & Regards,
