사용자 정의 확장에 카테고리 트리 추가

제품 편집 페이지의 탭 중 하나에있는 카테고리 트리 인 맞춤 확장에 카테고리 트리를 추가하려고합니다.

자신을 준비하십시오, 이것은 긴 것이 될 것입니다. 간다
다음 파일이 필요합니다.

사용자 지정 엔터티의 탭을 추가하는 양식 파일에서 다음을 추가하십시오.

    $this->addTab('categories', array(
        'label' => Mage::helper('[module]')->__('Associated categories'),
        'url'   => $this->getUrl('*/*/categories', array('_current' => true)),
        'class'    => 'ajax'
    ));

사용자 지정 엔터티의 관리자 컨트롤러에서 범주에 대한 요청을 처리하는이 두 가지 작업 :

public function categoriesAction(){
    $this->_init[Entity]();
    $this->loadLayout();
    $this->renderLayout();
}
public function categoriesJsonAction(){
    $this->_init[Entity]();
    $this->getResponse()->setBody(
        $this->getLayout()->createBlock('[module]/adminhtml_[entity]_edit_tab_categories')
            ->getCategoryChildrenJson($this->getRequest()->getParam('category'))
    );
}

동일한 컨트롤러 에이 방법이 있는지 확인하십시오.

protected function _init[Entity](){
    $[entity]Id  = (int) $this->getRequest()->getParam('id');
    $[enity]    = Mage::getModel('[module]/[entity]');

    if ($[entity]Id) {
        $[entity]->load($[entity]Id);
    }
    Mage::register('current_[entity]', $[entity]);
    return $[entity];
}

모듈의 관리자 레이아웃 파일에서 카테고리 조치에이 핸들을 추가하십시오.

<adminhtml_[module]_[entity]_categories>
    <block type="core/text_list" name="root" output="toHtml">
        <block type="[module]/adminhtml_[entity]_edit_tab_categories" name="[entity].edit.tab.categories"/>
    </block>
</adminhtml_[module]_[entity]_categories>

이제 데이터 저장을 진행하겠습니다.
이를 위해 모듈의 설치 / 업그레이드 스크립트 중 하나에 다음이 필요합니다. 연결된 값이 저장 될 테이블이 생성됩니다

$table = $this->getConnection()
    ->newTable($this->getTable('[module]/[entity]_category'))
    ->addColumn('rel_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        'unsigned'  => true,
        'identity'  => true,
        'nullable'  => false,
        'primary'   => true,
        ), 'Relation ID')
    ->addColumn('[entity]_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        'unsigned'  => true,
        'nullable'  => false,
        'default'   => '0',
    ), '[Entity] ID')
    ->addColumn('category_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        'unsigned'  => true,
        'nullable'  => false,
        'default'   => '0',
    ), 'Category ID')
    ->addColumn('position', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        'nullable'  => false,
        'default'   => '0',
    ), 'Position')
    ->addIndex($this->getIdxName('[module]/[entity]_category', array('category_id')), array('category_id'))
    ->addForeignKey($this->getFkName('[module]/[entity]_category', '[entity]_id', '[module]/[entity]', 'entity_id'), '[entity]_id', $this->getTable('[module]/[entity]'), 'entity_id', Varien_Db_Ddl_Table::ACTION_CASCADE, Varien_Db_Ddl_Table::ACTION_CASCADE)
    ->addForeignKey($this->getFkName('[module]/[entity]_category', 'category_id', 'catalog/category', 'entity_id'),    'category_id', $this->getTable('catalog/category'), 'entity_id', Varien_Db_Ddl_Table::ACTION_CASCADE, Varien_Db_Ddl_Table::ACTION_CASCADE)
    ->addIndex(
    $this->getIdxName(
        '[module]/[entity]_category',
        array('[entity]_id', 'category_id'),
        Varien_Db_Adapter_Interface::INDEX_TYPE_UNIQUE
    ),
    array('[entity]_id', 'category_id'),
    array('type' => Varien_Db_Adapter_Interface::INDEX_TYPE_UNIQUE))
    ->setComment('[Entity] to Category Linkage Table');
$this->getConnection()->createTable($table);

테이블을 선언하십시오. 태그 config.xml안에 이것을 추가하십시오<[module]_resource><entities>

<[entity]_category>
    <table>[module]_[entity]_category</table>
</[entity]_category>

카테고리에 연결하려면 모델이 필요합니다.
app/code/local/[Namespace]/[Module]/Model/[Entity]/Category.php

<?php

class [Namespace]_[Module]_Model_[Entity]_Category
    extends Mage_Core_Model_Abstract {
    protected function _construct(){
        $this->_init('[module]/[entity]_category');
    }
    public function save[Entity]Relation($[entity]){
        $data = $[entity]->getCategoriesData();
        if (!is_null($data)) {
            $this->_getResource()->save[Entity]Relation($[entity], $data);
        }
        return $this;
    }
    public function getCategoryCollection($[entity]){
        $collection = Mage::getResourceModel('[module]/[entity]_category_collection')
            ->add[Entity]Filter($[entity]);
        return $collection;
    }
}

그리고 자원 모델 app/code/local/[Namespace]/[Module]/Model/Resource/[Entity]/Category.php:

<?php

class [Namespace]_[Module]_Model_Resource_[Entity]_Category
    extends Mage_Core_Model_Resource_Db_Abstract {

    protected function  _construct(){
        $this->_init('[module]/[entity]_category', 'rel_id');
    }
    public function save[Entity]Relation($[entity], $data){
        if (!is_array($data)) {
            $data = array();
        }
        $deleteCondition = $this->_getWriteAdapter()->quoteInto('[entity]_id=?', $[entity]->getId());
        $this->_getWriteAdapter()->delete($this->getMainTable(), $deleteCondition);

        foreach ($data as $categoryId) {
            if (!empty($categoryId)){
                $this->_getWriteAdapter()->insert($this->getMainTable(), array(
                    '[entity]_id'      => $[entity]->getId(),
                    'category_id'     => $categoryId,
                    'position'      => 1
                ));
            }
        }
        return $this;
    }
}

및 콜렉션 자원 모델 : app/code/local/[Namespace]/[Module]/Model/Resource/[Entity]/Category/Collection.php

<?php
class [Namespace]_[Module]_Model_Resource_[Entity]_Category_Collection
    extends Mage_Catalog_Model_Resource_Category_Collection{
    protected $_joinedFields = false;
    public function joinFields(){
        if (!$this->_joinedFields){
            $this->getSelect()->join(
                array('related' => $this->getTable('[module]/[entity]_category')),
                'related.category_id = main_table.entity_id',
                array('position')
            );
            $this->_joinedFields = true;
        }
        return $this;
    }
    public function add[Entity]Filter($[entity]){
        if ($[entity] instanceof [Namespace]_[Module]_Model_[Entity]){
            $[entity] = $[entity]->getId();
        }
        if (!$this->_joinedFields){
            $this->joinFields();
        }
        $this->getSelect()->where('related.[entity]_id = ?', $[entity]);
        return $this;
    }
}

이제 관리자 컨트롤러의 saveAction에서 전화하기 전에 이것을 추가하십시오. $[entity]->save()

$categories = $this->getRequest()->getPost('category_ids', -1);
if ($categories != -1) {
    $categories = explode(',', $categories);
    $categories = array_unique($categories);
    $[entity]->setCategoriesData($categories);
}

엔티티 모델에서 클래스 맨 위에 이것을 추가하십시오 protected $_categoryInstance = null;.

protected function _afterSave() {
    $this->getCategoryInstance()->save[Entity]Relation($this);
    return parent::_afterSave();
}
public function getCategoryInstance(){
    if (!$this->_categoryInstance) {
        $this->_categoryInstance = Mage::getSingleton('[module]/[entity]_category');
    }
    return $this->_categoryInstance;
}
public function getSelectedCategories(){
    if (!$this->hasSelectedCategories()) {
        $categories = array();
        foreach ($this->getSelectedCategoriesCollection() as $category) {
            $categories[] = $category;
        }
        $this->setSelectedCategories($categories);
    }
    return $this->getData('selected_categories');
}
public function getSelectedCategoriesCollection(){
    $collection = $this->getCategoryInstance()->getCategoryCollection($this);
    return $collection;
}

그게 다야. 나는 아무것도 놓치지 않기를 바랍니다. 모듈이 정확히 어떻게 작성되었는지 모르지만 주요 아이디어가 있기 때문에 코드에 약간의 변경이 필요할 수 있습니다. 약간의 디버깅으로 작동하도록해야합니다.

_{참고 : 위의 코드는 Ultimate Module Creator v1.9를 사용하여 생성 되었습니다 .}

적어도 Magento 1.9의 경우 extJ가로드되어 있는지 확인해야합니다.
다음 방법 중 하나를 사용하여 백엔드에서 extJS 사용을 활성화하십시오.

1. 컨트롤러에서 이것을 사용하십시오 :

   $this->getLayout()->getBlock('head')->setCanLoadExtJs(true);

2. 레이아웃 xml에서 이것을 사용하십시오 :

   <reference name="head">
       <action method="setCanLoadExtJs">
           <value>1</value>
       </action>
   </reference>
