PHP SpecialPage::getRequest方法代码示例

 /**
  * Fetch informations about the user uploading, prepare prefixes list content, and
  * set the default item to select. It also updates the special page DestFileName 
  * attribute. Attached to hooks:
  * <ul>
  * <li>$wgHooks['UploadForm:initial']</li>
  * <li>$wgHooks['UploadForm:BeforeProcessing']</li>
  * </ul>
  * @param SpecialPage $specialUploadObj current SpecialUpload page object
  * @todo if the user cannot upload a new file, maybe this function should
  * however return true, as seen in SpecialUpload page code comments (but if
  * true returned, the form is displayed with our error message on top)
