Question

我无法从while循环获取规则点数据。请帮助我...... :(

以下是我的代码

<?php 
                                    $employee_query = $dbcon->query("SELECT * FROM employee ORDER BY name ASC");
                                    while($employee_array = $employee_query->fetch_array()):
                                    $employee_ids = $employee_array['id'];
                                    $department_ids = $employee_array['department_id'];

                                    $department_query = $dbcon->query("SELECT * FROM department WHERE id='$department_ids'");
                                    $department_array = $department_query->fetch_assoc();
                                ?>
                                <tr>
                                    <td> <small> <strong> <?= $employee_array['name']; ?> </strong> </small> </td>
                                    <td> <small> <strong> <?= $department_array['department']; ?> </strong> </small> </td>
                                    <td> <small> <strong> <?= $y; ?> </strong> </small> </td>
                                    <td> <small> <strong> <?= $m; ?> </strong> </small> </td>
                                    <td> <small> <strong> <?= $w; ?> Week </strong> </small> </td>
                                    <td> <small> <strong> <?= $pd['week_range']; ?> </strong> </small> </td>
                                    <td>
                                    <?php 
                                        $pm_query = $dbcon->query("SELECT * FROM performance_management WHERE performance_id='$pid' AND department_id='$department_ids' AND employee_id='$employee_ids'");
                                        while($pm_data = $pm_query->fetch_array()):
                                            echo $rules_ids = $pm_data['rules_id'];

                                            $rules_query = $dbcon->query("SELECT * FROM point WHERE rules_id='$rules_ids'");
                                            $rules_data = $rules_query->fetch_assoc();

                                            echo $rules_data['points'];
                                        endwhile;
                                    ?>
                                    </td>
                                </tr>

在上面的代码中，我无法获得$rules_data['points']

Answer 1

fetch_assoc()将所有row作为associative array返回。所以像这样访问它

echo $rules_data[0]['points'];

更新：

您的$rules_ids值为47,30,36，因此您需要使用IN clause查询

"SELECT * FROM point WHERE rules_id IN (".$rules_ids.")"
