Answer 1

你需要在你的php.ini中设置upload_max_filesize的值：

upload_max_filesize = 2M defalt upload_max_filesize = 5M

          (or)

你需要在代码config.php中添加以下行（root path public_html / application / config）

ini_set（'upload_max_filesize'，'5M'）;

          (or)

您需要添加以下代码行.htaccess php_value upload_max_filesize 5M

Answer 2

place the constructor inside or class inside it will work

class Home_model extends CI_Model {

/**
 * @return void
 * */
public function __construct() {
    parent::__construct();
    $this->load->helper("security");       
    ini_set('upload_max_filesize', '5M');
}
