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,需要在时间表列表中的每一行显示客户名称、作业名称和任务,每天时间在列表中是可编辑的,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中显示来自单独表的正确名称。

在其当前状态下,它返回正确的结果,并且除了链接到其他表之外工作得很好。

我在这个问题上疯了,因为我找不到解决方案,现在正遭受代码盲症的困扰。

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');
}

看法

$datestring = '%Y-%m-%d';
if (count($entry)){
    foreach ($entry as $key => $list){
        $dateNow = mdate($datestring);
        $entryId = $list['entry_id'];
        $sheet = $list['timesheet_id'];
        $clientId = $list['client_id'];
        $jobId = $list['job_id'];
        $taskId = $list['task_id'];
        $fridayHrs = $list['friday_hrs'];
        $saturdayHrs = $list['saturday_hrs'];
        $sundayHrs = $list['sunday_hrs'];
        $mondayHrs = $list['monday_hrs'];
        $tuesdayHrs = $list['tuesday_hrs'];
        $wednesdayHrs = $list['wednesday_hrs'];
        $thursdayHrs = $list['thursday_hrs'];
        echo '<tr>'
            .form_open('/timesheet/update_entry')
            .form_hidden('entry_id', $entryId)
            .form_hidden('timesheet_id', $sheet)
            .form_hidden('date_modified', $dateNow).
            '<td>'.$clientId.'</td>
            <td>'.$jobId.'</td>
            <td>'.$taskId.'</td>
            <td class="studio">'.form_input('monday_hrs', $mondayHrs).'</td>
            <td class="studio">'.form_input('tuesday_hrs', $tuesdayHrs).'</td>
            <td class="studio">'.form_input('wednesday_hrs', $wednesdayHrs).'</td>
            <td class="studio">'.form_input('thursday_hrs', $thursdayHrs).'</td>
            <td class="studio">'.form_input('friday_hrs', $fridayHrs).'</td>
            <td class="studio">'.form_input('saturday_hrs', $saturdayHrs).'</td>
            <td class="studio">'.form_input('sunday_hrs', $sundayHrs).'</td>
            <td class="icon">'.form_submit('', 'Update','class="update"').'</td>
            <td class="icon"><a href="/timesheet/edit_entry/'.$sheet.'/'.$entryId.'"><img src="/images/sitewide/edit.png" alt="Edit Entry" width="24" height="24" /></a></td>
            <td class="icon"><a href="/timesheet/delete_entry/'.$sheet.'/'.$entryId.'"><img src="/images/sitewide/delete.png" alt="Delete Entry" width="24" height="24" /></a></td>'
            .form_close()
            .'</form></tr>';    
    }
}

这些是相关表的数据库表模式

解决方案

由安德拉斯·拉茨提供

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; 
} 

视图需要有变量

$taskId = $list['task_id']; 

变成

$taskId = $list['task_name'];

排序谢谢:)

也许只有我一个人,但这似乎更适合数据库方面的事情。在不了解数据库结构的情况下,除了建议在数据库中创建一个视图来提供您想要的内容,然后从该视图中查询和返回数据之外,很难给出更多的建议。

因为你没有写表名,所以这里是一个例子。你需要改变你的模型。

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