Retrieve error backtrace - El Forum - 10-29-2007
[eluser]iive[/eluser]
I wonder is there any how I can retrieve the stacktrace when there is an error in our php coding or database error?
For example: let's say I have a database error in my Model, can CI trace back on the screen where this error comes from (the model name, the line in the model.php etc...)? Instead of I see the MySql error message and I have to search through my Models to see which of them contains errors..
I hope my question is clear... and I really hope to know the answer..
thanks!

Hello,
I have done a little bit of research on reading this but cannot find a stacktrace within the codeigniter framework. I know there is a debug_backtrace() in php4 / 5 and it works within codeigniter and may be what you want
You need to set db_debug to false in your config file, this will stop the MYSQL error page appearing and halting your application. (rollback needs db_debug to be false)
I have coded my applications to catch all database errors and report them cleanly.
I have mentioned this before in the forums so please forgive me for repeating myself :-S
what I have done is put all db calls into a function wrapper in a db_call model and then you can choose how to handle errors.
models/calldb.php
Code:
function insert($table, $data_array) {
$res = $this->db->insert($table,$data_array);
if (!$res) {
$errNo = $this->db->_error_number();
$errMess = $this->db->_error_message();
}
return array('ErrorN'=>$errNo,
'ErrorM'=>$errMess);
}
...
// need to implement delete update get getwhere etcyou can then handle db errors whenever they occur
Code:
$ret = $this->calldb->insert($table, $data_array, 1);
if ($ret['ErrorN']) {
...... what ever you want to do..., log the error, return it etc.
}
