Codeigniter Error Logs
in the php.ini file An error handler is set in system/codeigniter/CodeIgniter.php using set_error_handler - this error handler, _exception_handler, is found in system/codeigniter/Common.php The _exception_handler function ignores E_STRICT errors, calls the show_php_error function From the Exceptions system library if the severity is that specified by your error_reporting() function in index.php and logs the error according to whatever you have set up in your config.php file The handler returns FALSE so after this PHP goes on to handle the error however it normally would according your error_reporting level and display_errors setting. 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('foo'); in a controller, the handler doesn’t get called. Any sug

Exception Handling In Codeigniter
CodeIgniter SonalFebruary 9, 2015, 2 years ago008.5K Today we are going to codeigniter try catch understand the error handling especially in CI in this Error Handling in CodeIgniter tutorial. PHP has various levels codeigniter log_message of error reporting for different errors. What level of error we get when we run our script depends on our server configuration. The decision to show the error on screen http://stackoverflow.com/questions/14778377/error-handling-in-codeigniter or not, is controlled by the server setting called display_errors. The developer may or may not have access to the underlying server setting such as display_errors. So the underlying settings are unknown to us. These settings are made known to us by codeigniter by the use of error_reporting() function on every page call, which overrides the settings of display_errors. This error_reporting() https://www.eduonix.com/blog/web-programming-tutorials/error-handling-codeigniter/ is found in the main index.php file. Error functions in codeigniter are simple procedural interfaces that are available globally throughout the application, hence the error messages are triggered without caring about the class/function scope. CodeIgniter helps us to report errors into our applications by using the following functions: show_error(): This function displays the error message using the template in application/errors/error_general.php. Syntax of show_error() function is: PHP show_error(‘message’,status_code); 1 show_error(‘message’,status_code);
Here, the parameter message is mandatory and is the string error message to be shown. The parameter status_code is optional which is an integer value representing the HTTP status code to be sent with the error. Example: PHP show_error(‘File not found!’); 1 show_error(‘File not found!’); show_404(): This function displays the 404 error message supplied to it by the template in application/errors/error_404.php. Syntax of show_404() function is: PHP show_404(‘page’[,’log_error’]); 1 show_404(‘page’[,’log_error’]); The first parameter page in show_404() function is the path of the page that is not found. In general we can see that 404 messages are shown by codeigniter automatically, if the controllers are not found.

Advanced Search Custom error handling Mark Croxton Posted: 01 December 2009 01:59 PM Joined: 2002-10-08316 posts I would like to intercept the expression engine error messages before they are output to the browser. My idea is to store the error message in the session, redirect to the original page (the return to link), grab the message from the session and display it on the original page. This would allow inline error messages. I've got this working easily for freeform using the extension hooks freeform_module_validate_end and freeform_module_form_end (see attached). I would now like to get this to work for member registration, login and profile forms. Unfortunately there are no hooks that I can find that intercept the form processing at the validation and form rendering stages. Also, frustratingly there are no hooks for show_message and show_user_error in the core output class. Are there any hooks that I've missed that might be used for this purpose? If not, is it possible to overload the core classes like you can in CI? Any other ideas?
