Question

我有一个问题，如果有人可以帮助我，我需要一些指示。

我正在使用CodeIgniter并且需要在时间表列表中显示每行的客户端名称，作业名称和任务，每天都可以在列表中编辑，但上面的3个字段是静态的。目前我显示存储在timesheetEntries表中的客户端，作业和任务的id，但我需要在时间表条目的每一行的单独表格中显示正确的名称。

在当前状态下，它会返回corretc结果，并且与链接到其他表格之间的效果很好。

由于我无法找到解决方案，我现在已经忘记了这个问题，现在我正在遭遇代码盲。

非常感谢

模型

function getAllEntriesByTimesheet($id){
    $data = array();
    $options = array('timesheet_id' => $id);
    $Q = $this->db->get_where('timesheetEntries', $options);
    if ($Q->num_rows() > 0){
        foreach ($Q->result_array() as $row){
            $data[] = $row;
        }
    }
    $Q->free_result();    
    return $data; 
}

控制器

function id($id){
    $data['title'] = 'Timesheets';
    $data['entry'] = $this->timesheet_model->getAllEntriesByTimesheet($id);
    $data['sheet'] = $this->uri->segment(3);
    $data['header'] = 'default/header';
    $data['main'] = 'timesheet_view';
    $data['footer'] = 'default/footer';
    $data['timesheettab'] = 'current';
    $data['expensestab'] = '';
    $data['holidaytab'] = '';
    $data['admintab'] = '';
    $this->load->vars($data);
    $this->load->view('default/default_view');
}

模型

function getAllEntriesByTimesheet($id){
    $data = array();
    $this->db->select('*');
    $this->db->join('tasks', 'tasks.task_id = timesheetEntries.task_id', 'left');
    $this->db->where('timesheetEntries.timesheet_id',$id);
    $Q = $this->db->get('timesheetEntries');
    if ($Q->num_rows() > 0){
        foreach ($Q->result_array() as $row){
            $data[] = $row;
        }
    }
    $Q->free_result();    
    return $data; 
}

View需要变量

$taskId = $list['task_id'];

更改为

$taskId = $list['task_name'];

排序谢谢：）

Answer 1

也许只是我，但这似乎更倾向于数据库方面。在不知道数据库结构的情况下，除了建议在数据库中创建一个能够提供所需内容然后从该视图中查询和返回数据的视图之外，很难给出更多信息。

Answer 2

因为您没有写表名，所以这是一个例子。你需要改变模型。

$this->db->select('*');
$this->db->from('timesheetEntries');
$this->db->join('otherTable', 'otherTable.id = timesheetEntries.taskId', 'left');
$this->db->where('timesheetEntries.timesheet_id',$id);
$Q = $this->db->get();

在$ this-＆gt; db-＆gt; get（）中，将get部分留空，因为使用from，您已经选择了表格。如果没有确切的表结构，则很难编写正确的语法。
