Batch Class

public class QuoteToPDFBatchDownload implements Database.Batchable, Database.Stateful {

public Integer recordsProcessed = 0;
public Database.QueryLocator start(Database.BatchableContext bc) {
    
    return Database.getQueryLocator([
        SELECT ID, Opportunity_Number__c FROM Quote WHERE SentToIFS__c =TRUE    
    ]);

}

public void execute(Database.BatchableContext bc, List scope){

    for (Quote qt : scope) {
        // PageReference pr = New PageReference('/apex/culliganReortDownload?id=' + qt.id ); 
        ApexPages.StandardController sc = new ApexPages.StandardController(qt);  
        QuoteToPDFControllerdownload qd = new QuoteToPDFControllerdownload(sc);
          recordsProcessed = recordsProcessed + 1;
    
}
}

public void finish(Database.BatchableContext bc){
     System.debug(recordsProcessed + ' records processed. Ayesha!');
}

}

Answer 1

I suggest you can try using the following statement, in Apex, in a custom controller, to access the id which you are passing via Batch class:

ApexPages.currentPage().getParameters().get('id');

Please let me know if it helps you out.

Thanks.
