Load Language from within an own Library - El Forum - 11-01-2009

Hey Guys,

i have created my own Language File and my own Class in the application/libaries Folder.

The Language is defined in the Configuration File and Autoloaded!

I have access to the File through the Views - there's no Problem, but when i try to access the Language File through my Libaries Class, i get an Error!!

How to fix that? In my own Library Class i have to define a Standard Message - and this one depends on the Language, so i need access to the File.

Hope everyone understands what i mean???

Greetings from Germany,

Sascha

Okay, that's the code of the Library:

Code:
class Displayerror 

 {

    function raiseError( $message = '' )

    {

        $return = '';

        if( empty( $message ) ) $message = $this->lang->line( 'error_undefined' );

        $return .= "\n".'<div class="error">'."\n";

        $return .= "\t".'<div class="message"><h1>Error</h1><span>'.$message.'</span></div>'."\n";

        $return .= '</div>'."\n";

        return $return;

    }

 }

An this is the Error:

Quote:A PHP Error was encountered

Severity: Notice

Message: Undefined property: Displayerror::$lang

Filename: libraries/Displayerror.php

Line Number: 19
Fatal error: Call to a member function line() on a non-object in /srv/www/vhosts/mydomain.de/httpdocs/application/libraries/Displayerror.php on line 19

Line 19 is that line:

Code:
if( empty( $message ) ) $message = $this->lang->line( 'error_undefined' );

Thanks,
Sascha

If thats the whole code, yoy forgot to use get_instance() so that you can use CI libraries. This can be found in the user guide

For example:

Code:
class Displayerror

{

    function Displayerror()

    {

        $this->CI =& get_instance();

    }

    function raiseError( $message = '' )

    {

        $return = '';

        if( empty( $message ) ) $message = $this->CI->lang->line( 'error_undefined' );

        $return .= "\n".'<div class="error">'."\n";

        $return .= "\t".'<div class="message"><h1>Error</h1><span>'.$message.'</span></div>'."\n";

        $return .= '</div>'."\n";

        return $return;

    }

}
