CakePHP：保存數據時出錯

Question

所以我遇到了麻煩，我的數據保存在CakePHP中。如果我上傳圖片（意思是['PictureForm'] ['file'] ['name']存在），一切正常，數據被保存。但是，如果['PictureForm'] ['file'] ['name']爲空，並且['PictureForm'] ['url']存在，則圖像被正確保存在磁盤上，但是$ this-> PictureForm - >保存（$ this-> data）失敗。

任何人看到任何公然錯誤的代碼？

if (isset($this->data['PictureForm'])) { 
          ///////////////////////////////////////////////////////DEV 
          if(!$this->data['PictureForm']['file']['name']) { 
            if (!$this->data['PictureForm']['url']) { 
              $this->Session->setFlash('Error: no image URL or file given!'); 
              $this->redirect(array('action' => '/')); 
            } else { 
              $fileExtension = getExtension($this->data['PictureForm']['url']); 
              $this->request->data['PictureForm']['filename'] = randFilename() . "." . $fileExtension; 
              file_put_contents('files/picture/' . $this->data['PictureForm']['filename'], file_get_contents($this->data['PictureForm']['url'])); 
            } 
          } else { //file was uploaded 
            $fileExtension = getExtension($this->data['PictureForm']['file']['name']); 
            if (!$fileExtension) { 
              $this->Session->setFlash('Error: no file extension!'); 
              $this->redirect(array('action' => '/')); 
            } 
            $this->request->data['PictureForm']['filename'] = randFilename() . "." . $fileExtension; 
            move_uploaded_file($this->data['PictureForm']['file']['tmp_name'], "files/picture/" . $this->data['PictureForm']['filename']); 
          } 
          $this->request->data = Sanitize::clean($this->request->data, array('encode' => false)); 
          if ($this->PictureForm->save($this->data)) { 
            resizeUpload($this->data['PictureForm']['filename']); 
            $this->Session->setFlash('Picture <a href="/spootur/media/p/' . $this->data['PictureForm']['filename'] . '">saved</a>'); 
            $this->redirect(array('action' => 'p/' . $this->data['PictureForm']['filename'])); 
          } else { 
            $this->Session->setFlash('Error: could not save to db' . $this->data['PictureForm']['filename']); 
            $this->redirect(array('action' => '/')); 
          } 
        }

如果保存失敗，在其他塊，而不是重定向嘗試查看驗證錯誤：

if ($this->PictureForm->save($this->data)) { 
    // code 
} else{ 
    debug($this->PictureForm->validationErrors); 
}
