undefined method Main::_remove_invisible_characters() with OCI8

[eluser]FabD[/eluser]
Hi,

I'm trying to make my first app with CodeIgniter and using ActiveRecord class with an Oracle database. I received this error message :

Call to undefined method Main::_remove_invisible_characters() in \system\database\drivers\oci8\oci8_driver.php on line 378

This the call stack :

The code is :

Code:

$this->db->select('soc_code,sp_code,matricule') ;
$this->db->from('groupe.sg_mp_signa');
$this->db->where('mps_initiales',$user);

Is there a bug ? If Yes is there a workaround ?

Thanks,

I just ran across that the other day. It appears to be the same bug that's documented here:

http://codeigniter.com/bug_tracker/bug/6752/

So, if you change

Code:

$this->_find_invisible...

to read

Code:

$this->input->_find_invisible...

you should be good.

Hopefully they'll merge this into the codebase.

BTW - how did you get that stacktrace printed out? Debugger? Or is there some PHP function that prints the stack trace when an error occurs? Thanks.

There are some native PHP functions: debug_backtrace(), debug_print_backtrace()
You can also use some PHP debuggers: Xdebug, DBG

If you update your drivers from the current subversion, this has been fixed, per the bug report linked above.

Thanks for your answers.
I use Xdebug as debugger. That's the easiest way using Eclipse/PDT.
