使用 cakephp 将复选框保存到单独的表中

【中文标题】使用 cakephp 将复选框保存到单独的表中

【英文标题】：Save checkboxes to separate table using cakephp

【发布时间】：2016-07-21 16:19:08

【问题描述】：

我有一些空间可以存放会产生费用的活动和物品。

在后端，我想添加一个空格和可能的费用，所以我有一个带有多个选择复选框的表单。

我希望它将事件空间 ID 写入到 facility_event_spaces_id 列，并将费用写入我的“event_charges”表中的 facility_event_charges_id 列。

它没有在我的表中保存任何东西，event_charges。 我的模型或控制器或两者中可能有一些不正确的地方。任何 cakephp 大师有建议吗？

我们正在运行 cakephp 1.3。谢谢！

<tr>
    <td class="add">Charges:</td>
    <td>
    <?php echo $this->Form->input('charge', array('type'=>'select', 'multiple' => 'checkbox', 'options'=>$charges)); ?>
    </td>         
    </tr>

添加表单源视图

<div class="checkbox"><input type="checkbox" name="data[FacilityEventSpace][charge][]" value="1" id="FacilityEventSpaceCharge1" /><label for="FacilityEventSpaceCharge1">Officials</label></div>
<div class="checkbox"><input type="checkbox" name="data[FacilityEventSpace][charge][]" value="2" id="FacilityEventSpaceCharge2" /><label for="FacilityEventSpaceCharge2">Ushers</label></div>
<div class="checkbox"><input type="checkbox" name="data[FacilityEventSpace][charge][]" value="3" id="FacilityEventSpaceCharge3" /><label for="FacilityEventSpaceCharge3">Additional Staffing</label></div>
<div class="checkbox"><input type="checkbox" name="data[FacilityEventSpace][charge][]" value="4" id="FacilityEventSpaceCharge4" /><label for="FacilityEventSpaceCharge4">Special Lighting</label></div>
<div class="checkbox"><input type="checkbox" name="data[FacilityEventSpace][charge][]" value="5" id="FacilityEventSpaceCharge5" /><label for="FacilityEventSpaceCharge5">Audio Visual Equipment</label></div>
<div class="checkbox"><input type="checkbox" name="data[FacilityEventSpace][charge][]" value="6" id="FacilityEventSpaceCharge6" /><label for="FacilityEventSpaceCharge6">Audio Visual Technician</label></div>

我创建的 joinTable 创建表event_charges ( id int (11) 非空， facility_event_spaces_id int(11) 非空， facility_event_charges_id int(11) 非空， 主键 (id) );

我的模特

<?php
class FacilityEventSpace extends AppModel 
var $name = 'FacilityEventSpace';
var $hasAndBelongstoMany = array('FacilityEventCharge' =>
                        array('className'    => 'FacilityEventCharge',
                              'joinTable' => 'event_charges',
                              'foreignKey'   => 'facility_event_spaces_id',
                              'associationForeignKey' => 'facility_event_charges_id',
                              'with' =>'EventCharge'
                        ),
                  );
 // end Model
?>

---

<?php
class FacilityEventCharge extends AppModel 

var $name = 'FacilityEventCharge';

 // end Model
?>

---

<?php
class EventCharge extends AppModel

 var $name = 'EventCharge';                     
 // end Model
?>

我的控制器 - facility_event_spaces_controller.php

功能添加

$this->set('charges', $this->FacilityEventCharge->find('list', array('fields' => array('id', 'type'))  ));
if (!empty($this->data)) 
    if($this->FacilityEventSpace->save($this->data))
                

                $this->flash('The event space has been saved.','/FacilityEventSpaces/');
                        return;

还有，这是 facility_event_charges 表

【参考方案1】：

我发现将数据保存到单独表格的一种方法是：

$maxId = $this->FacilityEventSpace->getMaxId();
                    // routines for Charges
                    $charges = $this->data['FacilityEventSpace']['charge'];
                    $n = 0;
                    foreach ($charges as $key => $cost) 

                        $charge = array('EventCharge'=>array(
                        'id'=>'',
                        'facility_event_spaces_id'=>$maxId[0][0]['max(id)'],
                        'facility_event_charges_id'=>$cost
                        )
                        );
                        $this->EventCharge->save($charge['EventCharge']);
                        $n = $n + 1;
                     // end charges

【讨论】：

由于我的复选框来自一个单独的表，'facility_event_charges' 和那些被“选中”的被保存到另一个表中，'event_charges' 我如何在我的 edit.ctp 文件中呈现，所有复选框，包括那些被选中的复选框？
