described below. In addition, it has an error logging class that permits error and debugging messages to be saved as text files. Note: By default, CodeIgniter displays all PHP errors. You might wish to codeigniter database error handling change this behavior once your development is complete. You'll find the error_reporting() function

located at the top of your main index.php file. Disabling error reporting will NOT prevent log files from being written if codeigniter error handling example there are errors. Unlike most systems in CodeIgniter, the error functions are simple procedural interfaces that are available globally throughout the application. This approach permits error messages to get triggered without having to worry
Codeigniter Log_message
about class/function scoping. The following functions let you generate errors: show_error('message' [, int $status_code= 500 ] ) This function will display the error message supplied to it using the following error template: application/errors/error_general.php The optional parameter $status_code determines what HTTP status code should be sent with the error. show_404('page' [, 'log_error']) This function will display the 404 error message supplied to it using the following error template: application/errors/error_404.php The codeigniter try catch function expects the string passed to it to be the file path to the page that isn't found. Note that CodeIgniter automatically shows 404 messages if controllers are not found. CodeIgniter automatically logs any show_404() calls. Setting the optional second parameter to FALSE will skip logging. log_message('level', 'message') This function lets you write messages to your log files. You must supply one of three "levels" in the first parameter, indicating what type of message it is (debug, error, info), with the message itself in the second parameter. Example: if ($some_var == "")
{
log_message('error', 'Some variable did not contain a value.');
}
else
{
log_message('debug', 'Some variable was correctly set');
}
log_message('info', 'The purpose of some variable is to provide some value.');
There are three message types: Error Messages. These are actual errors, such as PHP errors or user errors. Debug Messages. These are messages that assist in debugging. For example, if a class has been initialized, you could log this as debugging info. Informational Messages. These are the lowest priority messages, simply giving information regarding some process. CodeIgniter doesn't natively generate any info messages but you may want to in your appli

The thing that is puzzling me is that E_ERROR errors i.e. fatal errors don’t seem to be being caught by _exception_handler at all. It’s not just that show_php_error isn’t being called, it looks like the function just isn’t being called for them. This is obviously a problem as it means that they aren’t get handled by show_php_error or logged. For example if I deliberately mistype $this->load->views
errors. Note: The exception to this is Subscription PeopleCode. All errors for Subscription PeopleCode get logged to the application message https://docs.oracle.com/cd/E58500_01/pt854pbh1/eng/pt/tpcr/task_ErrorHandling-c07b72.html error table. Error messages include system error messages or messages from the message catalog (a common set of error messages used by all PeopleSoft applications.) For a Component Interface, the http://thecancerus.com/simple-way-to-add-global-exception-handling-in-codeigniter/ session object level errors also contain any text errors that may have occurred from running ExecuteEdits. On the session object, you can use the following properties to initially check error handling for errors: ErrorPending indicates whether there are API errors WarningPending indicates whether there are API warnings All errors are contained in the PSMessages collection. (The PSMessages property on a Session object returns this collection.) Each item in this collection is a PSMessage object. A PSMessage object contains information about the specific error that has occurred, such as the explain text ci error handling for the error, the message set number, and so on. (The type of information depends on the type of error.) If the error was caused by a Component Interface, a contextual string is attached to the end of the Text property of the PSMessage object. This contextual string contains the exact location of the error, that is, which field in which data collection, on which row, caused the error. This string is also accessible (by itself) using the Source property. When errors are loaded into the PSMessages collection depends on the type of error. System errors (that is, errors in the connection to the PeopleSoft Session) are logged as they occur. When an API error is logged depends on the API, as some APIs can be run in either interactive mode (meaning errors are logged as they happen) or in non-interactive mode (so errors are logged only when a particular method is run.) If you are using Visual Basic or another COM environment, the PeopleSoft API system raises a COM exception the first time ErrorPending changes from
for us to know. The idea was that whenever such an exception occur on production we should send an email to developers mailing list so that someone can investigate it. As usual I did a quick google search and i found two forum posts in CodeIgniter and one on stackoverflow, but they all fall short as CodeIgniter does not set’s any default exception handlers they way it sets the native error handler. So here is a quick tutorial on how you can do that. First of all you need to setup a hook, so put following code in hook.php file in config folder. $hook['pre_controller'][] = array( 'class' => 'ExceptionHook', 'function' => 'SetExceptionHandler', 'filename' => 'ExceptionHook.php', 'filepath' => 'hooks' ); Now I am using pre_controller hook as I wanted to use $CI object which is available at this stage. Now put the code shown below in the file named ExceptionHook.php in your application’s hooks folder. Also if you need to capture and email native PHP errors, you can do so by extending the Exceptions library as shown in the code below. While I have used the simple PHP mail function in the example above, you can use CI's mail library as well. If you have any doubts feel free to ask in comments below.
