codeigniter issues with DB and special characters

In your sql queries.

yup i have added the escap string in the sql driver..

PHP Code:

// escape LIKE condition wildcards
        if ($like === TRUE)
        {
            $str = str_replace(array('%', '_', '%ca'), array('\\%', '\\_', '\\%ca'), $str);
        }
        
        return $str; 


after saved, i reboot the db,  and when i insert 239.106.%card.%number

and save the txt data into my db it not stores only 239.106 no other data copied into the db

so it completelly wipes the data %card.%number
