UhOh is an extension on CI_Extensions that provides awesome error messages with full back traces and a view of the line with the error.

It catches all errors including:

E_PARSE
E_ERROR
E_USER_ERROR
E_COMPILE_ERROR
E_ERROR
E_USER_ERROR
E_PARSE
E_WARNING
E_USER_WARNING
E_STRICT
E_NOTICE
E_RECOVERABLE_ERROR

It also outputs full back traces for all CodeIgniter system errors. No more “Where is it trying to load that view?”, it will show you the line that called it and the surrounding lines.

UhOh! is based on Kohana v3’s error handling. The file contains some code from the Kohana project.

Let me know what you think or if you have issues.  Install instructions are in the README.

Had to fix line 87 of MY_Exceptions.php:

$file = 'APPPATH/'.substr($file, strlen(ABS_APPPATH);

$file = 'APPPATH/'.substr($file, strlen(ABS_APPPATH));

I love it… but loading a missing view just gives me the show_error() error from the router (attached), and only after an exceedingly long load time. I’m using modular separation (tested in both 1.7.2 and 2.0) which I imagine is the cause.

You must be running an old version.  Please re-download and re-install.  There is a new errors/error_general.php file as well.

Thanks,

Sorry, I was wrong.  Just fixed the first issue and re-tagged.

Missed the part that said you were running Modular Separation too…I am fixing that.

Dan

Just posted version 1.3 which fixes the issue with Modular Separation.  Please re-download the MY_Exceptions.php file and replace the existing one.

Thanx a lot! Greate hook!

I said some few words about it at russian - http://mpak666.livejournal.com/540424.html

noctrum how u fixed the error on line 87 ?

it seams i have the same error (i use ci2)

Notice: Use of undefined constant ABS_APPPATH - assumed 'ABS_APPPATH' in C:\wamp\www\final\application\core\MY_Exceptions.php  on line 182

Warning: require(ABS_APPPATHerrors/error_php_custom.php) [function.require]: failed to open stream: No such file or directory in C:\wamp\www\final\application\core\MY_Exceptions.php on line 182

Fatal error: require() [function.require]: Failed opening required 'ABS_APPPATHerrors/error_php_custom.php' (include_path='.;C:\\php5\\pear') in C:\wamp\www\final\application\core\MY_Exceptions.php on line 182

This isn’t the same error, the error I had was on line 87, yours is online 182. I just had to add an extra parenthesis to the end of the statement, which I posted. Dan fixed it almost immediately after that, so unless you downloaded it before I did you don’t have that problem.

ABS_APPPATH is defined in the hook, so you probably haven’t enabled hooks.

the hooks are enabled i will have to do some debuging

Great lib! Already helped me out a lot during bugfixing.

i won’t use this for the same reason i don’t buy paper towels: because i don’t make mistakes. just kidding, nice library 😊

Thanks Dan, I will be using this library to speed up debugging in some upcoming projects.

edit (wrong thread)

the hooks are enabled i will have to do some debuging

I’m getting the same error (running CI 1.5.4). I did not get the error running the exact same downloaded zip file of uhoh on a different server (running CI 1.7.2). The second server is mine and is a fresh install of CI with the only hook being uhoh. The one that fails is an inherited server which has Authlib also installed and enabled. There are also many other changes on that server which I couldn’t begin to enumerate since I don’t know them all. :|

It looks like one of three things is happening:

- uhoh doesn’t like CI 1.5.4
- uhoh doesn’t like Authlib
- some other change that was made to the inherited server is conflicting with uhoh

Unfortunately adding uhoh to the server it died on was a side project, not a requirement, so I don’t know when I’ll be able to look deeper. If anyone else is experiencing this and can give some more info (or even a fix 😛 ), that’d be great.

I should probably add that I’ve been using uhoh on the server that works and it’s great. Thanks a lot for the hard work that went into making our lives easier! :D
