我使用嵌套的foreach，第一，我在第一个foreach中显示所有员工第二，我想显示出席和缺席的员工出勤率从出勤表我将employee_id与employee_id的员工表匹配它显示所有现有员工，并正确显示缺席员工。任何帮助，请

我发布了图片，你可以看到，我显示所有员工，我正在检查employee-id = employee-id（表示存在于考勤表中）。如果存在则显示“存在”否则“缺席”。但它过度循环。

Answer 1

SELECT e.*, CASE WHEN (a.attendance_id is null) THEN 'absent' ELSE 'present' END as presentinfo FROM `employee` e left join attendance a on e.employee_id=a.employee_id and a.date=date(now())

您的Html页面如下所示：

           <tr class="gradeX">
                <td><?php echo $emp->first_name.' '.$emp->last_name ?></td>
                <td><?php echo $emp->employee_number ?></td>
                <td><?php echo $emp->presentinfo ?></td>
           </tr> 

            <?php } ?>
        </tbody>

我的建议：使用上面的查询..它会显示您需要的结果。

尝试以下

你的模特

public  function get_attendance () {

    $arrEmployee = $this->db->get('employee')->result();

    $arrEmployeeById = array();
    $arrEmployeeIds = array();
    foreach($arrEmployee AS $objEmployee)
    {
        $objEmployee->arrAttendance = array();
        $arrEmployeeById[$objEmployee->employee_id] = $objEmployee;
        $arrEmployeeIds[] = $objEmployee->employee_id;
    }

    $this->db->where_in("A.employee_id",$arrEmployeeIds);
    $arrAttendances = $this->attendance();

    foreach($arrAttendances AS $objAttendence)
    {
        if (isset($arrEmployeeById[$objAttendence->employee_id]))   $arrEmployeeById[$objAttendence->employee_id]->arrAttendance[] = $objAttendence;
    }

    return $arrEmployee;

    //return $this->db->get('employee')->result();
}

public function attendance() 
{
    $today = date('Y-m-d');  // get today date
    $this->db->where('A.date',$today)->from('attendance A')
    //->join('employee E','E.employee_id = A.employee_id','LEFT');
    return $this->db->get()->result();
}

你的控制器

public function admin() {
    $data['employee'] = $this->attendance_model->get_attendance();
    $data['header'] = "Employee";
    $data['sub_header'] = "Attendance employee";
    $data['main_content'] = 'attendance/admin_list';
    $this->load->view('employeelayout/main',$data);
}

//你的观点

<thead>
    <tr>
        <th>#</th>             
        <th>Employee Name</th>
        <th>Employee Number</th>
         <th>Today</th>
        <th>Mark Incoming</th>       
        <th class="hidden-phone">Status</th>
    </tr>
</thead>

<tbody>
    <?php $count = 1; ?>
    <?php foreach($employee as $emp) {  ?>

   <tr class="gradeX">
        <td><?php echo $count ++ ?></td>
        <td><?php echo $emp->first_name.' '.$emp->last_name ?></td>
        <td><?php echo $emp->employee_number ?></td>
        <?php 
        if (count($emp->arrAttendance) > 0)
        {
            foreach($emp->arrAttendance as $atten) {  
        ?>
                <td><?php echo $atten->date ?></td>
                <td><?php echo $atten->mark_in_time ?></td>
                <td><?php echo "present" ?></td>
        <?php
            }
        }
        else 
        {  
        ?>
            <td></td>
            <td></td>
            <td><?php echo "absent" ?></td>
        <?php } ?>
   </tr> 
    <?php } ?>
</tbody>

使用if else语句嵌入forloop php codeigniter
