系统学习magento二次开发,推荐小册:《Magento中文全栈二次开发 》
本小册面向Magento2以上版本,书代码及示例兼容magento2.0-2.4版本。涵盖了magento前端开发,后端开发,magento2主题,magento2重写,magento2 layout,magento2控制器,magento2 block等相关内容,带领您成为magento开发技术专家。
在 Magento 2 中,可以通过配置锁定来保护配置值,确保它们不被修改。这在多人团队开发环境中非常有用,可以防止一些开发人员无意中修改了其他人的配置。
要使用配置锁定,需要创建一个配置锁定提供程序。以下是一个示例:
<?php
namespace Vendor\Module\Model\Config\Provider;
use Magento\Framework\App\Config\Value;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Framework\App\Config\ValueFactory;
use Magento\Framework\Serialize\Serializer\Json;
class LockProvider
{
const XML_PATH_CONFIG_LOCK = 'lock/path/to/config';
/**
* @var ValueFactory
*/
protected $configValueFactory;
/**
* @var ScopeConfigInterface
*/
protected $scopeConfig;
/**
* @var Json
*/
protected $jsonSerializer;
/**
* LockProvider constructor.
* @param ValueFactory $configValueFactory
* @param ScopeConfigInterface $scopeConfig
* @param Json $jsonSerializer
*/
public function __construct(
ValueFactory $configValueFactory,
ScopeConfigInterface $scopeConfig,
Json $jsonSerializer
) {
$this->configValueFactory = $configValueFactory;
$this->scopeConfig = $scopeConfig;
$this->jsonSerializer = $jsonSerializer;
}
/**
* Get the locked config value.
*
* @return mixed
*/
public function getLockedConfigValue()
{
$lockedConfigValue = $this->scopeConfig->getValue(self::XML_PATH_CONFIG_LOCK);
if ($lockedConfigValue) {
$lockedConfigValue = $this->jsonSerializer->unserialize($lockedConfigValue);
}
return $lockedConfigValue;
}
/**
* Set the locked config value.
*
* @param mixed $value
* @param string $scope
* @param int $scopeId
* @return bool
*/
public function setLockedConfigValue($value, $scope = 'default', $scopeId = 0)
{
$existingValue = $this->getLockedConfigValue();
if ($existingValue === null) {
$configValue = $this->configValueFactory->create();
$configValue->setScope($scope);
$configValue->setScopeId($scopeId);
$configValue->setPath(self::XML_PATH_CONFIG_LOCK);
$configValue->setValue($this->jsonSerializer->serialize($value));
$configValue->save();
return true;
}
return false;
}
/**
* Delete the locked config value.
*
* @param string $scope
* @param int $scopeId
* @return bool
*/
public function deleteLockedConfigValue($scope = 'default', $scopeId = 0)
{
$existingValue = $this->getLockedConfigValue();
if ($existingValue !== null) {
$configValue = $this->configValueFactory->create();
$configValue->setScope($scope);
$configValue->setScopeId($scopeId);
$configValue->setPath(self::XML_PATH_CONFIG_LOCK);
$configValue->delete();
return true;
}
return false;
}
}
