正如标题所说，我正在使用插件中的设置模型访问组件的设置，但得到的结果是空白的，而不是存储在DB中的当前值。这就是我正在做的。首先，这是我的fields.yaml文件定义：
fields:
sandbox_enabled:
label: Activar modo Sandbox?
type: checkbox
default: false
ppal_fee:
label: Cargo de PayPal
type: text
ppal_discount:
label: Descuento por transferencias
type: text
ppal_app_id_sandbox:
label: PayPal Sandbox App ID (*)
type: text
ppal_developer_account:
label: PayPal Developer Account Email Address (*)
type: text
ppal_api_username_sandbox:
label: PayPal Username API Credentials (Sandbox) (*)
type: text
ppal_api_password_sandbox:
label: PayPal Password API Credentials (Sandbox) (*)
type: text
ppal_api_signature_sandbox:
label: PayPal Signature API Credentials (Sandbox) (*)
type: text
ppal_rest_client_id_sandbox:
label: PayPal REST API Username Credentials (Sandbox) (*)
type: text
ppal_rest_client_secret_sandbox:
label: PayPal REST API Secret Credentials (Sandbox) (*)
type: text
第二，alomicuba.recharge.settings在DB:记录值
{
"sandbox_enabled":"1",
"ppal_fee":"0.029",
"ppal_discount":"0.30",
"ppal_app_id_sandbox":"",
"ppal_developer_account":"",
"ppal_api_username_sandbox":"",
"ppal_api_password_sandbox":"",
"ppal_api_signature_sandbox":"",
"ppal_rest_client_id_sandbox":"",
"ppal_rest_client_secret_sandbox":""
}
最后，我是如何获得组件中设置的值的：
public function onAmountChange()
{
// The user amount
$amount = post('amount');
if (empty($amount))
{
throw new 'Exception(sprintf('Por favor introduzca un valor.'));
}
$toReload = $amount - ($amount * Settings::get('ppal_fee') - Settings::get('ppal_discount'));
$this->page["confirmation_text"] = $toReload;
}
但它不起作用，因为这两个值Settings::get('ppal_fee')，Settings::get('ppal_discount')为空，为什么？我做错了什么？
您在顶部指定了以下代码行吗？
use Alomicuba'Recharge'Models'Settings;
如果您已经指定，然后尝试使用以下代码行：
$settings = Settings::instance();
$settings->ppal_fee;
所有的功能代码看起来都像这个
public function onAmountChange()
{
// The user amount
$amount = post('amount');
if (empty($amount))
{
throw new 'Exception(sprintf('Por favor introduzca un valor.'));
}
$settings = Settings::instance();
$toReload = $amount - ($amount * $settings->ppal_fee - $settings->ppal_discount);
$this->page["confirmation_text"] = $toReload;
}
