[eluser]SaSa[/eluser]
i want convert a class to libraries but not work libraries,

I put the code for best help:

my original class:

Code:

<?php
/*
* GregorianToJalali & JalaliToGregorian Converter
* GregorianToJalali Function source : http://www.farsiweb.info/jalali/jalali.phps
*
*
*    $test = new Converter;
*        $g2j = $test->GregorianToJalali('2000','10','10');
*            echo $g2j[0]." ".$g2j[1]." ".$g2j[2];
*        $j2g = $test->JalaliToGregorian('1386','12','26');
*            echo $j2g[0]." ".$j2g[1]." ".$j2g[2];

i load libraries to config/autoload.php and run this code to view:

Code:

$test = new Converter;
        $j2g = $test->JalaliToGregorian('1390','04','20');
            echo $j2g[0]." ".$j2g[1]." ".$j2g[2];//Class END
                        $g2j = $test->GregorianToJalali('2000','10','10');
            echo $g2j[0]." ".$g2j[1]." ".$g2j[2];

to view have this error:

Code:

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: test

Fatal error: Call to a member function JalaliToGregorian() on a non-object in D:\xampp\htdocs\system\core\Loader.php(679) : eval()'d code on line 116

Sorry, that was too much. Please help me solve this problem.

Please help me

[eluser]Unknown[/eluser]
Try this code :

Code:

$j2g = $this->convert_date->JalaliToGregorian('1390','04','20');
echo $j2g[0]." ".$j2g[1]." ".$j2g[2];//Class END
$g2j = $this->convert_date->GregorianToJalali('2000','10','10');
echo $g2j[0]." ".$g2j[1]." ".$g2j[2];

Best regards

You don't need to do this: $test = new Converter;

Just
$this->load->library('convert_date');

But, you said you autoload it, so you wouldn't need the above line to instantiate it as it already is.
$result = $this->convert_date->JalaliToGregorian('1390','04','20');
