Php Fatal Error Cannot Access Empty Property
in PHP up vote 7 down vote favorite 1 I have derived a class from Exception, basically like so: class MyException extends Exception { private $_type; public function type() { return $this->_type; //line 74 } public function __toString() { include "sometemplate.php"; return ""; } } Then, I derived from MyException like so: class SpecialException extends MyException { private $_type = "superspecial"; } If I throw new SpecialException("bla") fatal error cannot access protected property pdoexception from a function, catch it, and go echo $e, then the __toString function should load a template, display that, and then not actually return anything to echo. This is basically what's in the template file
message; ?>
in my mind, this should definitely work. However, I get the following error when an exception is thrown and I try to display it: Fatal error: Cannot access private property SpecialException::$_type in C:\path\to\exceptions.php on line 74 Can anyone explain why I am breaking the rules here? Am I doing something horribly witty with this code? Is there a much more idiomatic way to handle this situation? The point of the $_type variable is (as shown) that I want a different div class to be used depending on the type of exception caught. php oop exception share|improve this question edited Nov 19 '09 at 10:21 tuergeist 4,67112448 asked Nov 19 '09 at 9:53 Carson Myers 15.9k2397144 As I wrote down there: It is very very very ugly to let __toString() return an empty string. I really can't see ANY usecase for such stuff. –tuergeist Nov 19 '09 at 10:29here for a quick overview of the site Help Center Detailed answers to any questions you might have media card cannot access fatal error Meta Discuss the workings and policies of this site About Us cannot access private property symfony2 Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with access private variable in php us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just http://stackoverflow.com/questions/1762135/accessing-private-variable-from-member-function-in-php like you, helping each other.

With the $this->$my_value = .. syntax, you set the property
topic 146.115.5.162 (talkcontribs) Hi, trying to resolve an issue with file uploads. Uploading works fine, but upon successful upload, the user goes to a blank page (i.e. a PHP error). The error is: PHP Fatal error: Cannot access private property https://www.mediawiki.org/wiki/Thread:Project:Support_desk/Fatal_error:_cannot_access_private_property/reply LocalFile::$description in /var/www/w/includes/filerepo/file/File.php on line 205, referer: http://[our wiki site]/wiki/Special:Upload. Files appear on the wiki fine, so at this point, it's mostly annoying. Google's not turning up anything similar. Any thoughts? Reply 21:10, 27 August 2014 2 years ago Permalink Hide 88.130.124.240 (talkcontribs) Which version of MediaWiki are you using? Do you maybe have a problem after you did an update? E.g. that you have not replaced all files with the new ones? Do cannot access you use any extensions, which somehow manipulate file upload in some way? Reply 21:31, 27 August 2014 2 years ago Permalink Hide 146.115.5.162 (talkcontribs) Using MediaWiki 1.23.1 and PHP 5.5.9. Not using many extensions, and none that are related to file uploads. Reply 22:29, 27 August 2014 2 years ago Permalink Hide Ciencia Al Poder (talkcontribs) I'd suggest to download the latest 1.23 version and reupload it again on your server. This seems like fatal error cannot you upgraded over an old installation and some files left unmodified with the old version. It would be good if you unpack all new files on an empty folder and copy over your data (LocalSettings.php, extensions, and uploads if they're in subdirectories of the installation) Reply 09:32, 28 August 2014 2 years ago Permalink Hide 18.207.1.184 (talkcontribs) I downloaded and upgraded to a fresh copy of 1.23.3. Copied over my LocalSettings, logo and favicon files, and 3 extensions I use -- BreadCrumbs, MobileFrontend, and HipchatNotifications. Upgrade went fine, no issues at all viewing pages, I go to upload a file... exact same error. I feel like this must be external to MediaWiki, but don't know how to debug PHP in this instance. Reply 15:37, 28 August 2014 2 years ago Permalink Hide Florianschmidtwelzow (talkcontribs) First: The error message above is from your apache error_log, right? Can you enable error reporting in php to see the error's directly on the page (instead of a white page?). Information how to do this, you can find here. Maybe there are other erros, too? Reply 17:36, 28 August 2014 2 years ago Permalink Hide Ciencia Al Poder (talkcontribs) Yes, an error backtrace would be incredibly useful here. Be sure to set $wgShowExceptionDetails = true; Reply 18:50, 28 August 2014 2 years ago Permalink Hide 146.115.5.16
