我想创建两个输入字段。一个将保存一个Int,另一个将保存一个K-0001之类的值。保存这些输入字段并重新加载表单后,我想在字段中查看它们保存到数据库中的最后一个值。
之所以要这样做,是因为这样,我只能需要更改最后一位数字,然后可以再次保存表格。问题是我不知道该怎么做。
更好的解释示例:
形成:
字段1:第一个值20000。我输入数字20001。
栏位2:第一个值K-0000。我输入文字K-0001。
保存并重新加载表单后,我希望它看起来像这样。
字段1:显示值20001。我将其更改为20005。
栏位2:显示值K-0001。我将其更改为K-0005。
再次:
字段1:显示值20005。我将其更改为20007。
栏位2:显示值K-0005。我将其更改为K-0007。
等等
我想我需要创建一个从数据库中获取值的函数。之后,我需要将它们放入“输入字段”中,至少这是我的想法。
代码:
add.ctp
div class="customers form large-9 medium-8 columns content">
<?= $this->Form->create($customer) ?>
<fieldset>
<legend><?= __('Neuen Kunden erstellen') ?></legend>
<?php
echo $this->Form->control('tour_id', ['options' => $tours, 'empty' => true]);
/* echo $this->Form->control('order', array('label' => __('Bestellung', true))); */

我希望我对目标的解释足够好,并且没有忘记什么。我仍在学习,因此,如果我放弃某些内容,请告诉我,然后我将编辑我的问题。

找到我的解决方案!
我在Controller内创建了一个函数,以获取所需的值:
CustomersController.php
$query = $this->Customers->find('list', [
'order' => ['Customers.kdnr' => 'DESC'],
'valueField' => 'kdnr',
'limit' => 1]);
$kdnr = $query->first();
$kdnr++;
$query = $this->Customers->find('list', [
'order' => ['Customers.debinr' => 'DESC'],
'valueField' => 'debinr',
'limit' => 1]);
$debinr = $query->first();
$debinr++;
$this->set(compact('customer', 'tours', 'kdnr', 'debinr'));
之后,我只需要将$ kdnr和$ debinr添加到ctp中即可。
add.ctp
echo $this->Form->control('kdnr',['value' => $kdnr]);
echo $this->Form->control('debinr',['value' => $debinr]);
那是我要做的。
