选择姓名员工ID
类别地点雇员姓名
声称每人的装量

数量

只需在函数
fetchDataFromTable

差不多


public function fetchDataFromTable()
{
    $arrRows = $this->input->post('checkbox[]');
    if (!empty($arrRows))   $this->db->where_in('id', $arrRows);
    $query =$this->db->get('jc_meeting_expense');
    ...
}


在您的视图中，只需将您的
id
作为值放入
复选框
元素中即可


<td><input type="checkbox" id="checkbox" name="checkbox[]" value="<?php echo $row->id; ?>"></td> 



请检查以下代码

控制器（welcome.php）



Emp_ID

嘿，我在fetchDataFromTable和我的视图中都做了更改。但现在我遇到以下错误：遇到PHP错误严重性：注意消息：未定义属性：stdClass:：$id Filename:JcMeetingExpense/jc_meeting_expense.PHP行号：439“>我解决了这个错误，我只是在网站url中使用了formaction属性。但是，我再次在excel中获取除一个特定行之外的所有数据。请查看您的
复选框中的内容
变量它工作正常，但在excel报告中，我仅获取选中行的员工ID。。。。我需要检查过的员工@Parth viramgam的所有记录，并正确记录我的评论，我已将其放入控制器文件中。。您需要编写代码从数据库中获取记录并将其传递到报表视图文件。目前，您只有一个ID，因为它是用于解决问题的公正和虚拟记录。
