make CI throw an exception when it encounters a DB error instead of displaying a message like: A Database Error Occurred Error Number: 1054 Unknown column 'foo' in 'where clause' SELECT * FROM (`FooBar`) WHERE `foo` = '1' NOTE: I only want this to happen in one controller. In the other controllers, I'm happy for it to display the DB error messages. php codeigniter share|improve this question edited Oct 20 '11 at codeigniter error handling 23:29 asked Oct 20 '11 at 23:22 StackOverflowNewbie 9,96467186337 add a comment| 7 Answers 7 active oldest votes up vote 34 down vote accepted Try these CI functions $this->db->_error_message(); (mysql_error equivalent) $this->db->_error_number(); (mysql_errno equivalent) share|improve this answer edited Oct 21 '11 at 4:22 answered Oct 21 '11 at 4:17 Oskenso Kashi 51147 3 And when the queries are dinamically created, $this->db->last_query() useful too. –uzsolt Oct 21 '11 at 15:17 5 How do these prevent the messages from displaying? –StackOverflowNewbie Oct 21 '11 at 21:36 7 You must turn debug off for database in config/database.php -> $db['default']['db_debug'] = FALSE; –decebal Dec 12 '12 at 12:47 8 Why is not possible to use Exception instead :-( ? –Thomas Decaux Mar 8 '13 at 11:39 16 These methods have been removed in CodeIgniter version 3.

Codeigniter Db Error
on this topic in the CI forum, StackOverflow and elsewhere. I tried to do my http://stackoverflow.com/questions/7843406/codeigniter-how-to-catch-db-errors research carefully but it seems to me, that I did not find a proper answer. The question is how to handle database transaction errors and not to loose the error http://forum.codeigniter.com/archive/index.php?thread-1255.html details. The CI guide suggested way is PHP Code: $this->db->trans_start();
$this->db->query('ANSQLQUERY...');
$this->db->query('ANOTHERQUERY...');
$this->db->trans_complete();
if($this->db->trans_status()===FALSE)

It is very annoying for the users if the errors are not handled properly. CodeIgniter provides an easy error handling mechanism. You would like the messages to be displayed, when the application is in developing mode rather than in production mode as the error messages can be solved easily at the developing stage. The environment of your application can be changed, by changing the line given below from index.php file. This can be set to anything but normally there are three values (development, test, production) used for this purpose. define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development'); Different environment will require different levels of error reporting. By default, development mode will display errors and testing and live mode will hide them. CodeIgniter provides three functions as shown below to handle errors. show_error() function displays errors in HTML format at the top of the screen. Syntax show_error($message, $status_code, $heading = 'An Error Was Encountered') Parameters $message (mixed) − Error message $status_code (int) − HTTP Response status code $heading (string) − Error page heading Return Type mixed show_404() function displays error if you are trying to access a page which does not exist. Syntax show_404($page = '', $log_error = TRUE) Parameter
