我想将数据库中的文件导出为excel文件，但是...
这是我的功能：
$path_file = './assets/report/excel/';
$styleBorder = array();
$data = array();
$data['param'] = array(
"start_date" => $this->input->post('start_date'),

这是我的get_all_trx_petugas函数，下面是代码：
function get_all_trx_petugas($petugas="",$start_date="",$end_date=""){
$CI = getCI();
$petugas = !empty($petugas)?"AND norekPetugas LIKE '%$petugas%'":'';
$m = $CI->db->query("
select DATE_FORMAT(dateTrx, '%d %M %Y') as tgl,
COUNT(if(trxType = '21', idTransaksi, NULL)) as setor,
COUNT(if(trxType = '01', idTransaksi, NULL)) as tarik,
COUNT(if(trxType = '49', idTransaksi, NULL)) as transfer,
SUM(if(trxType = '21', amount, 0)) as amount_setor,
SUM(if(trxType = '01', amount, 0)) as amount_tarik,
SUM(if(trxType = '49', amount, 0)) as amount_transfer
FROM transaksi
WHERE DATE_FORMAT(dateTrx,'%Y-%m-%d') >= '$start_date' AND DATE_FORMAT(dateTrx,'%Y-%m-%d') <= '$end_date'
$petugas
GROUP BY DATE_FORMAT(dateTrx,'%Y-%m-%d')
ORDER BY DATE_FORMAT(dateTrx,'%Y-%m-%d') ASC
")->result();
return $m;
}
excel文件始终为空
请帮助我。
