Hi Michael Dsoza,
 My scenario is like  this link e.g: https://www.salesforce.com/customers .(please refer this link) then, If I click any one image link my vfp-1 redirect to another vfp, that second page display the details of company information.
I was linked one visualforce page to another vfp.,
vfp -1 
<apex:outputLink target="_blank" value="{!$Page.custrefdetail}"  >   
 <apex:image value="{!account.photo__c}" height="150" width="200"   />


In my second visuaforce page i call the one method hello1
  
<apex:page sidebar="false" showHeader="false" controller="sfdctest" action="{!hello1}" >
<apex:form >
  <apex:pageBlock >
    <apex:repeat value="{!accprd}" var="accs">
        {!accs.Detail__c}   
   </apex:repeat> 
        </apex:pageBlock>
     </apex:form>


controller:
  
public Void hello1(){
    accprd = New List<accproducts__c>();
     accprd = [SELECT Detail__c from  accproducts__c where Product__r.name =:productName  andaccount__c in (select ID from Account where industry=:searchStr)];
System.debug(productName);
   }


above the query productName  and  searchStr input comming from vfp -1.
In vfp-2  I call an action hello1,but a controller not known the productName  & searchStr  values. it return the value as null.Any code clarification please refer my first post.If you knows please tell me..

Thanks,
M. Sivasankari

Hi Sivasankari,

As you are using _target that means on clicking, you are opening new window. Also, you are passing URL as "$Page.custrefdetail". If you are passing parameter in URL then get the parameter value in Controller Use - ApexPages.currentPage().getParameters().get('keyName');
And If you are not passing parameter then set the parameter to make it accessible on second page.
Hope it will help you.
Mark Resolved. If it solves your query.

Hi Michael Dsoza,

I tried below code,
  
public PageReference  hello1(){
       
      String  searchStr1= ApexPages.currentPage().getParameters().get('searchStr');
    String productName1 = ApexPages.currentPage().getParameters().get('productName');
   accprd = New List<accproducts__c>(); 
 	accprd = [SELECT Detail__c,Product__c from  accproducts__c where Product__c =:productName1  and account__c in (select ID from Account where industry=:searchStr1)];
	
      System.debug(productName1);
       System.debug(searchStr1);
    	PageReference pagr= new PageReference('/apex/custrefdetail');   
           pagr.setRedirect(true); 
     
        return pagr;
}

but the value shows as null..

Thanks,
Sivasankari.
