Question

这是我的代码

$attendanceDetail = $this->common->getWhere('tbl_attendance', 'date', $allDate);
$total = $attendanceDetail->num_rows();
if($total >0 )
{
    echo "record found";
}
else{
    echo "Not Found";
}

如何获取查询结果中的记录总数？

Answer 1

试试这个：将此方法放在模型中

public function count_records($table_name) {
     return $this->db->count_all($table_name);
}

count_all是查询构建器类方法，它返回表中记录的总数，参见here

在你的控制器方法中使用它：

$total_records = $this->your_model->count_records('put_table_name_here');

Answer 2

$attendanceDetail = $this->common->getWhere('tbl_attendance', 'date', $allDate);
$total = count($attendanceDetail);
if($total >0 )
{
   echo "record found";
}
else{
    echo "Not Found";
 }

如何使用codeigniter获取查询中的记录总数？
