Question

如何获取名称而不仅仅是ID？
我实际上在数据表中是这样的：
Current Datatable
但是我需要的是显示区域名称而不是ID。我尝试这样做：

<table aria-describedby="dataTable_info" cellspacing="0" class="table table-hover dataTable" id="dataTable" role="grid" style="width:100%;" width="100%">
                        <thead>
                            <tr>
                                <th>Areas</th>
                                <th>Auditorias</th>
                            </tr>
                        </thead>
                        <tbody>
                            {% for audit in auditsByArea %}
                                    <tr>
                                        <td>{{ audit.id_Area.name }}</td>
                                        <td>{{ audit.Audits }} <input style="width:0.8cm; height:0.8cm;background-color:##E4E8E9; border-radius: 8px; border-color:#3A93B2"  class ="mx-2" data-id="4" data-area="{{ audit.id_Area }}"data-responsible="4" data-startDate="<?php date('n/d/Y');?>" id="auditBtn" name="auditBtn" type='text' readonly  data-toggle="modal" data-target="#auditModal"></input></td>
                                    </tr> 
                            {% endfor %}
                        </tbody>
                    </table>

但出现以下错误：
无法访问字符串变量（“ 1”）上的属性（“名称”）。

有关修复此问题的想法或建议吗？还是出什么问题了？

这是我转储AuditsByArea的结果：

    array (size=3)
  0 => 
    array (size=2)
      'id_Area' => string '1' (length=1)
      'Audits' => string '1,2,3,4' (length=7)
  1 => 
    array (size=2)
      'id_Area' => string '3' (length=1)
      'Audits' => string '12,11,10,9' (length=10)
  2 => 
    array (size=2)
      'id_Area' => string '5' (length=1)
      'Audits' => string '17,18,19,20' (length=11)

Table of fsa_Areas

Table of fsa_Audits

Answer 1

在您写的评论中，您的查询是：

SELECT id_Area, GROUP_CONCAT(id_Audit) as Audits 
FROM helios.fsa_audits 
WHERE id_Auditor='$AuditorId' 
GROUP BY id_Area;

添加要输出的信息：

SELECT id_Area, area.Name as area_name, GROUP_CONCAT(id_Audit) as Audits 
FROM helios.fsa_audits 
LEFT JOIN helios.fas_areas area USING (id_Area)
WHERE id_Auditor='$AuditorId' 
GROUP BY id_Area;

，您可以通过以下方式在循环中访问它：

{{ audit.area_name }}

但是，请注意，您使用的是纯PHP数组，带有“手动” SQL查询，而没有ORM所提供的功能。
