Prestashop 1.7.7 - HelperForm在Multistore上下文中

Question

我正在测试multistore兼容模块的第一个简单版本。它只有两个设置，必须根据当前商店上下文(主要是单个商店)以不同的方式保存。现在，我知道从1.7.8有额外的复选框在BO表单中的每个设置，但我必须设法让它也为1.7.7工作。现在，Configuration::updateValue()和Configuration::get()都应该是多存储就绪的，这意味着它们只更新或检索当前上下文的值，所以应该没问题。奇怪的是，在安装测试模块后，如果我转到配置页面，它会自动重定向到All-Shop上下文，如果我尝试手动切换(从右上方的下拉菜单)，它会显示一个空白页面。如果我试图取消激活底部复选框"激活这个模块在上下文中:all shop "

下面是我的代码:

class TestModule extends Module
{
public function __construct()
{
$this->name = 'testmodule';
$this->tab = 'front_office_features';
$this->version = '1.0.0';
$this->author = 'Test';
$this->need_instance = 1;
$this->ps_versions_compliancy = [
'min' => '1.7.0.0',
'max' => '1.7.8.0',
];
$this->bootstrap = true;
parent::__construct();
$this->displayName = $this->l("Test Module");
$this->description = $this->l('Collection of custom test extensions');
$this->confirmUninstall = $this->l('Are you sure you want to uninstall?');
if (!Configuration::get('TESTM_v')) {
$this->warning = $this->l('No version provided');
}
}
public function install()
{
if (Shop::isFeatureActive()) {
Shop::setContext(Shop::CONTEXT_ALL);
}
return (
parent::install() 
&& $this->registerHook('header')
&& $this->registerHook('backOfficeHeader')
&& Configuration::updateValue('TESTM_v', $this->version)
); 
}
public function uninstall()
{
if (Shop::isFeatureActive()) {
Shop::setContext(Shop::CONTEXT_ALL);
}
return (
parent::uninstall() 
&& $this->unregisterHook('header')
&& $this->unregisterHook('backOfficeHeader')
&& Configuration::deleteByName('TESTM_v')
);
}
public function getContent()
{
// this part is executed only when the form is submitted
if (Tools::isSubmit('submit' . $this->name)) {
// retrieve the value set by the user
$configValue1 = (string) Tools::getValue('TESTM_CONFIG_1');
$configValue2 = (string) Tools::getValue('TESTM_CONFIG_2');
// check that the value 1 is valid
if (empty($configValue1)) {
// invalid value, show an error
$output = $this->displayError($this->l('Invalid Configuration value'));
} else {
// value is ok, update it and display a confirmation message
Configuration::updateValue('TESTM_CONFIG_1', $configValue1);
$output = $this->displayConfirmation($this->l('Settings updated'));
}
// check that the value 2 is valid
Configuration::updateValue('TESTM_CONFIG_2', $configValue2);
$output = $this->displayConfirmation($this->l('Settings updated'));
}
// display any message, then the form
return $output . $this->displayForm();
}
public function displayForm()
{    
// Init Fields form array
$form = [
'form' => [
'legend' => [
'title' => $this->l('Settings'),
],
'input' => [
[
'type' => 'text',
'label' => $this->l('Custom CSS file-name.'),
'name' => 'TESTM_CONFIG_1',
'size' => 20,
'required' => true,
],
[
'type' => 'switch',
'label' => $this->l('Enable custom CSS loading.'),
'name' => 'TESTM_CONFIG_2',
'is_bool' => true,
'desc' => $this->l('required'),
'values' => array(
array(
'id' => 'sw1_on',
'value' => 1,
'label' => $this->l('Enabled')
),
array(
'id' => 'sw1_off',
'value' => 0,
'label' => $this->l('Disabled')
)
)
],
],
'submit' => [
'title' => $this->l('Save'),
'class' => 'btn btn-default pull-right',
],
],
];
$helper = new HelperForm();
// Module, token and currentIndex
$helper->table = $this->table;
$helper->name_controller = $this->name;
$helper->token = Tools::getAdminTokenLite('AdminModules');
$helper->currentIndex = AdminController::$currentIndex . '&' . http_build_query(['configure' => $this->name]);
$helper->submit_action = 'submit' . $this->name;
// Default language
$helper->default_form_language = (int) Configuration::get('PS_LANG_DEFAULT');
// Load current value into the form or take default
$helper->fields_value['TESTM_CONFIG_1'] = Tools::getValue('TESTM_CONFIG_1', Configuration::get('TESTM_CONFIG_1'));
$helper->fields_value['TESTM_CONFIG_2'] = Tools::getValue('TESTM_CONFIG_2', Configuration::get('TESTM_CONFIG_2'));
return $helper->generateForm([$form]);
}
/**

*/
public function hookHeader()
{
//$this->context->controller->addJS($this->_path.'/views/js/front.js');
if (Configuration::get('TESTM_CONFIG_2') == 1) {
$this->context->controller->addCSS($this->_path.'/views/css/'.((string)Configuration::get('TESTM_CONFIG_1')));
} else {
$this->context->controller->removeCSS($this->_path.'/views/css/'.((string)Configuration::get('TESTM_CONFIG_1')));
}
}
}

正如你所看到的，这是一个非常简单的设置:只需加载一个自定义的CSS文件，并选择是否加载它。我查看了Multistore处理的官方PS文档，并在网上搜索了一下，但没有找到这个特定问题的答案。我还试着添加:

if (Shop::isFeatureActive()) {
$currentIdShop = Shop::getContextShopID();
Shop::setContext(Shop::CONTEXT_SHOP, $currentIdShop);
}

到'displayForm()'函数，但没有结果。

提前谢谢你。

Answer 1

似乎是缓存错误。在尝试了许多变化之后，我可以确认我尝试的第一个解决方案是正确的，这意味着:

if (Shop::isFeatureActive()) {
$currentIdShop = Shop::getContextShopID();
Shop::setContext(Shop::CONTEXT_SHOP, $currentIdShop);
}

需要加上"displayForm()"函数，使其在选择单个商店时工作。值现在正确地保存在数据库中。通过一点额外的逻辑，可以安排它在为"所有商店"存钱时表现不同(如果需要的话)。上下文。
