我试图通过我的表单提取用户提交的数据，并且不做任何事情，除以100，或者根据字段乘以1,000,000。
我在编写可以成功执行此操作的beforeSave（）函数时遇到问题。当我禁用验证时，数据会提交，但我想要发生的数学运算不会发生。
我之所以这样做是因为如果用户输入2.16为2.16％，我们希望将其存储为.0216。表格提交后，它只是基本的数学，对于我的生活，我无法让它发挥作用。
任何建议都将不胜感激。 Haven没有找到关于这个主题的任何好的教程，所以如果有人知道任何有用的东西。
这是我从提交中获得的原始数据数组：
Array
(
[Subfirmdetail] => Array
(
[subfirm_id] => 4
[subfirmdetailtype_id] => 55
[value] => 20
[date] => 2011-12-02
[active] => yes
[modified] => 2011-12-02 19:00:06
[created] => 2011-12-02 19:00:06
)
)
Array
(
[Subfirmdetail] => Array
(
[subfirm_id] => 4
[subfirmdetailtype_id] => 56
[value] => 20
[date] => 2011-12-02
[active] => yes
[modified] => 2011-12-02 19:00:06
[created] => 2011-12-02 19:00:06
)
)
Array
(
[Subfirmdetail] => Array
(
[subfirm_id] => 4
[subfirmdetailtype_id] => 57
[value] => 20
[date] => 2011-12-02
[active] => yes
[modified] => 2011-12-02 19:00:06
[created] => 2011-12-02 19:00:06
)
)
Array
(
[Subfirmdetail] => Array
(
[subfirm_id] => 4
[subfirmdetailtype_id] => 58
[value] => 20
[date] => 2011-12-02
[active] => yes
[modified] => 2011-12-02 19:00:06
[created] => 2011-12-02 19:00:06
)
)
Array
(
[Subfirmdetail] => Array
(
[subfirm_id] => 4
[subfirmdetailtype_id] => 59
[value] => 20
[date] => 2011-12-02
[active] => yes
[modified] => 2011-12-02 19:00:06
[created] => 2011-12-02 19:00:06
)
)
这是我的beforeSave函数：
function beforeSave() {
switch($this->data['Subfirmdetailtype']['calculation']) {
case 0:
$this->data['Subfirmdetail']['value'] = $this->data['Subfirmdetail']['value'];
break;
case 1:
$this->data['Subfirmdetail']['value'] = $this->divide($this->data['Subfirmdetail']['value']);
break;
case 2:
$this->data['Subfirmdetail']['value'] = $this->multiply($this->data['Subfirmdetail']['value']);
break;
}
pr($this->data);
return true;
}

答案 0 :(得分：0)
您确定switch语句正确执行吗？我在代码示例中的任何地方都没有看到对此数据的引用，但您在交换机中调用它。
$this->data['Subfirmdetailtype']['calculation']
我建议将这些内容放在一边，看看你遇到了什么案例：
debug('Hello case n');
die;

这是我最终使用的。不得不对我的模型进行一些更改，并将数据拉入适当的部分。如果有人需要做类似的事情......我来帮忙。
function divide($number) {
return $number / 100;
}
function multiply($number) {
return $number * 1000000;
}
function beforeSave() {
switch($this->data['Subfirmdetail']['calculation']) {
case "divide":
$this->data['Subfirmdetail']['value'] = $this->divide($this->data['Subfirmdetail']['value']);
break;
case "multiply":
$this->data['Subfirmdetail']['value'] = $this->multiply($this->data['Subfirmdetail']['value']);
break;
case "none":
default:
$this->data['Subfirmdetail']['value'] = $this->data['Subfirmdetail']['value'];
break;
}
return true;
}
