Variable does not exist: standardController

On line 10 of my Class, I get the error listed in the subject line above.  Unsure how to resolve.  I am working on adding the attachments option to my VF Page listed below as well.  Please help!!

public class VFAttachments {
        public Id recordId;

    public VFAttachments() {

    public VFAttachments(ApexPages.StandardController controller) {
        this.recordId = (Trip_Report__c)standardController.getRecord().Id;

public Attachment attachment {
  get {
      if (attachment == null)
        attachment = new Attachment();
      return attachment;

  public PageReference upload() {

    attachment.OwnerId = UserInfo.getUserId();
    attachment.ParentId = recordId; // the record the file is attached to
 //   attachment.ParentId = ApexPages.currentPage().getParameters().get('id'); 
    attachment.IsPrivate = true;

    try {
      insert attachment;
    } catch (DMLException e) {
      ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Error uploading attachment'));
      return null;
    } finally {
      attachment = new Attachment(); 

    ApexPages.addMessage(new ApexPages.message(ApexPages.severity.INFO,'Attachment uploaded successfully'));
    return null;

Hi Patrick Sluck 5,
This error occured because you use wrong validable  in this line "this.recordId = (Trip_Report__c)standardController.getRecord().Id ",
you need to use this line in your code "this.recordId = (Trip_Report__c)controller.getRecord().Id".
I think this may help you.Please mark it best if it helps you.

Hemant is right above. Use controller rather than standardController variable.
