自定义library 参数传递错误,请大家帮忙

wnpers

自定义了一个library
application/library/myReadFilter
它是一个第三类的接口实现:代码如下

PHP复制代码

class MyReadFilter implements PHPExcel_Reader_IReadFilter
{      
        private $_startRow = 0;
        private $_endRow = 0;
        private $_columns = array();
 
        /**  Get the list of rows and columns to read  */
        public function __construct($startRow, $endRow, $columns)
        {
                $this->_startRow = $startRow;
                $this->_endRow = $endRow;
                $this->_columns = $columns;
        }
 
        public function readCell($column, $row, $worksheetName = '')
        {       //  Only read the rows and columns that were configured
                if ($row >= $this->_startRow && $row <= $_endRow) {
                        if (in_array($column, $this->_columns)) {
                                return true;
                        }
                }
                return false;
        }
}

我在控制器函数中:

PHP复制代码

 
//导入library
$this->load->library('myReadFilter');
// 生成对象
$filterSubset = new MyReadFilter(1,2,range('A', 'B'));
 
 

复制代码

错误:

请参考 upload的使用方法：

PHP复制代码

               
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size']     = '100';
$config['max_width']  = '1024';
$config['max_height']  = '768';
 
$this->load->library('upload', $config);
 

复制代码

希望对你有帮助 :)
