cake php重定向到空白页面

Question

Edit1: when my directory is www/cake/cake2.1/app it works fine but when its www/cake/app i am facing the problem below.

Hi i have just started off with cake php was doing the blog tutorial. I am trying to create a form and store the values in db as per tutorial i followed all the steps.

The problem is the values are getting stored into Db but i am redirected into a blank page.

controller:

<?php
class PostsController extends AppController {

    public $helpers = array('Html', 'Form');

    public function index(){
        $this->set('posts', $this->Post->find('all'));
    }

    function view($id = null) {        
        $this->Post->id = $id;        
        $this->set('post', $this->Post->read());    
    }
    function add(){
        if($this->request->is('post')){
            if($this->Post->save($this->request->data)){
                $this->Session->setFlash('Your post has been saved.');
                $this->redirect(array('action'=>'index'));
            }else{
                $this->Session->setFlash('Unable to add your post.');
            }
        }
    }
}

the redirect is not happening properly it displays a blank page with url hxxp://localhost/cake/posts/add

even tried $this->redirect('http://www.google.com'); doesn't work any help guys ?

post model:

<?php
class Post extends AppModel {
    public $validate = array(
        'title' => array(
            'rule' => 'notEmpty'
        ),
        'body' => array(
            'rule' => 'notEmpty'
        )
    );
}

Answer 1

It might be due to white space in end of file

Please check your file if white space is there after '?>' tag it redirects it to blank page

or you can remove '?>'(closing php tag) to remove this problem.

You have syntax errors. You have two closing } at the end of your add() method. Remove one and it should be fine.

Also worth keeping an eye on the error log at /app/tmp/log/error.log which will alert you of errors like this.
