Magento 2覆盖自定义模块
Magento 2覆盖自定义模块
提问于 2019-03-01 19:44:45
总之，我正在尝试覆盖第三方模块，以便在admin Ui上包含一个额外的下拉菜单
这是Prince/Productattach/Block/Adminhtml/Productattach/Edit/Tab/Main.php上的第三方文件
namespace Prince\Productattach\Block\Adminhtml\Productattach\Edit\Tab;
/**
*Class Main
*@package Prince\Productattach\Block\Adminhtml\Productattach\Edit\Tab
*/
class Main extends \Magento\Backend\Block\Widget\Form\Generic implements
\Magento\Backend\Block\Widget\Tab\TabInterface
{
/**
* @var \Magento\Store\Model\System\Store
*/
private $systemStore;
/**
* @var \Magento\Customer\Model\ResourceModel\Group\Collection
*/
private $customerCollection;
/**
* Main constructor.
* @param \Magento\Backend\Block\Template\Context $context
* @param \Magento\Framework\Registry $registry
* @param \Magento\Framework\Data\FormFactory $formFactory

* @param \Magento\Customer\Model\ResourceModel\Group\Collection $customerCollection
* @param array $data
*/
public function __construct(
\Magento\Backend\Block\Template\Context $context,
\Magento\Framework\Registry $registry,
\Magento\Framework\Data\FormFactory $formFactory,
\Magento\Store\Model\System\Store $systemStore,
\Magento\Customer\Model\ResourceModel\Group\Collection $customerCollection,
array $data = []
) {
$this->_systemStore = $systemStore;
$this->_customerCollection = $customerCollection;
parent::__construct($context, $registry, $formFactory, $data);
}
/**
* Prepare form
*
* @return $this
*/
public function _prepareForm()
{
$model = $this->_coreRegistry->registry('productattach');
/*
* Checking if user have permissions to save information
*/
if ($this->_isAllowedAction('Prince_Productattach::save')) {
$isElementDisabled = false;
} else {
$isElementDisabled = true;
}
/** @var \Magento\Framework\Data\Form $form */
$form = $this->_formFactory->create();
$form->setHtmlIdPrefix('productattach_main_');
$fieldset = $form->addFieldset(
'base_fieldset',
['legend' => __('Attachment Information')]
);
$customerGroup = $this->customerCollection->toOptionArray();
if ($model->getId()) {
$fieldset->addField('productattach_id', 'hidden', ['name' => 'productattach_id']);
}
$fieldset->addField(
'name',
'text',
[
'name' => 'name',

);
$fieldset->addField(
'description',
'textarea',
[
'name' => 'description',
'label' => __('Description'),
'title' => __('Description'),
'disabled' => $isElementDisabled
]
);
$fieldset->addField(
'files',
'file',
[
'name' => 'file',
'label' => __('File'),
'title' => __('File'),
'required' => false,
'note' => 'File size must be less than 2 Mb.', // TODO: show ACCTUAL file-size
'disabled' => $isElementDisabled
]
);
$fieldset->addType(
'uploadedfile',
\Prince\Productattach\Block\Adminhtml\Productattach\Renderer\FileIconAdmin::class
);
$fieldset->addField(
'file',
'uploadedfile',
[
'name' => 'uploadedfile',

);
$fieldset->addField(

[
'name' => 'url',
'label' => __('URL'),
'title' => __('URL'),
'required' => false,
'disabled' => $isElementDisabled,
'note' => 'Upload file or Enter url'
]
);
$fieldset->addField(
'customer_group',
'multiselect',
[
'name' => 'customer_group[]',
'label' => __('Customer Group'),
'title' => __('Customer Group'),
'required' => true,
'value' => [0,1,2,3], // todo: preselect ALL customer groups, not just 0-3
'values' => $customerGroup,
'disabled' => $isElementDisabled
]
);
$fieldset->addField(
'store',
'multiselect',
[
'name' => 'store[]',

);
$fieldset->addField(

'select',

'label' => __('Active'),
'title' => __('Active'),
'value' => 1,
'options' => ['1' => __('Yes'), '0' => __('No')],
'disabled' => $isElementDisabled
]
);
$this->_eventManager->dispatch('adminhtml_productattach_edit_tab_main_prepare_form', ['form' => $form]);
if ($model->getId()) {
$form->setValues($model->getData());
}
$this->setForm($form);
return parent::_prepareForm();
}
/**

public function getTabLabel()
{
return __('Attachment Information');
}

public function _isAllowedAction($resourceId)

}我用下面常用的加号配置了我的模块设置和di.xml，以覆盖该类。
<preference for="Prince\Productattach\Block\Adminhtml\Productattach\Edit\Tab" type="Vendor\Filecategory\Block\Adminhtml\Productattach\Edit\Tab"/>然后是类的精确副本，名称空间和我在Vendor/Filecategory/Block/Adminhtml/Productattach/Edit/Tab/Main.php中添加的额外字段
namespace Vendor\Filecategory\Block\Adminhtml\Productattach\Edit\Tab;
use \Prince\Productattach\Block\Adminhtml\Productattach\Edit\Tab\Main as Main;
class MainExt extends Main
{
/**

}然而，我一直收到错误
Incompatible argument type: Required type: \Magento\Store\Model\System\Store. Actual type: array; 我尝试过刷新缓存和重新建立索引，但没有成功。有人能告诉我我哪里做错了吗？也乐于倾听任何替代的方式来完成同样的事情。
提前谢谢。

我通过创建一个插件类来完成这个任务，而不是覆盖整个类。我已经为任何有兴趣添加表单字段到附加到第三部分模块的现有表单的人附上了我所关注的帖子。
