Reg:Doubt in page reference

Hi All,
In my scenario ,
Select page(input)-select industry and product
User-added image

Select page-click image
User-added image

Detail page- it shows relevant information about the image
User-added image

but in my case the detail page could not shows any informations.it couldn't receive any input from previous page(Select page).
My Code is:
Vfp-1(select page)
  
<apex:commandLink target="_blank" action="{!hello1}">
<apex:image value="{!account.photo__c}" height="150" width="200" id="test"   /> 
    
    </apex:commandLink>


My Controller page: 
public PageReference  hello1(){
       PageReference pagr= new PageReference('/apex/custrefdetail');   
String searchStr1=ApexPages.currentPage().getParameters().get('searchStr'); //input - industry
     String productName1=ApexPages.currentPage().getParameters().get('productName');//input - product

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);//product
      System.debug(searchStr1);//industry
              pagr.setRedirect(false); 
             return pagr;
	}
product and industry values shows as null. I dont know how to pass the detail value in visualforce page2.

if anybody knows please tell me.

Thanks,
M. Sivasankari.

It's hard to know exactly what's going on with the little information provided.  It would help if you could post the entire VF page and entire controller.  However, what I suspect is going on is the following:

You're not setting the values prior to displaying them in Visualforce.  It looks like you're setting productName1, searchString1 or any other fields prior to displaying them.

It could also be that your secondary or "custrefdetail" page is not reading the correct parameters in.

I would add some system.debug lines to your controller to see if your variables are getting set properly and go from there.
