Bereite dich vor, das wird lang. Hier geht.
Sie benötigen folgende Dateien:

Fügen Sie in Ihrer Formulardatei, in der Sie die Registerkarten Ihrer benutzerdefinierten Entität hinzufügen, Folgendes hinzu:
$this->addTab('categories', array(
'label' => Mage::helper('[module]')->__('Associated categories'),
'url' => $this->getUrl('*/*/categories', array('_current' => true)),
'class' => 'ajax'
));
Im Administrator-Controller Ihrer benutzerdefinierten Entität werden die folgenden 2 Aktionen ausgeführt, mit denen die Anforderungen für Kategorien verarbeitet werden:
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'))
);
}
und stellen Sie sicher, dass diese Methode in demselben Controller vorhanden ist:
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];
}
Fügen Sie in der Admin-Layout-Datei Ihres Moduls dieses Handle für die Aktion "Kategorien" hinzu:
<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>
Fahren wir nun mit dem Speichern Ihrer Daten fort.
Dazu benötigen Sie Folgendes in einem der Installations- / Upgrade-Skripte Ihres Moduls. Dadurch wird eine Tabelle erstellt, in der die verknüpften Werte gespeichert werden
$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);
Deklarieren Sie Ihren Tisch. Fügen Sie dies in config.xml
das <[module]_resource><entities>
Tag ein
<[entity]_category>
<table>[module]_[entity]_category</table>
</[entity]_category>
Sie benötigen ein Modell für die Verknüpfung mit Kategorien:
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;
}
}
und ein Ressourcenmodell 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;
}
}
und ein Sammlungsressourcenmodell: 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;
}
}
Fügen Sie dies jetzt in der saveAction Ihres Admin-Controllers vor dem Aufruf hinzu $[entity]->save()
$categories = $this->getRequest()->getPost('category_ids', -1);
if ($categories != -1) {
$categories = explode(',', $categories);
$categories = array_unique($categories);
$[entity]->setCategoriesData($categories);
}
Fügen Sie in Ihrem Entitätsmodell Folgendes am Anfang Ihrer Klasse hinzu: protected $_categoryInstance = null;
und diese Methoden an einer beliebigen Stelle:
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;
}
Das ist alles. Ich hoffe ich habe nichts verpasst. Der Code erfordert möglicherweise einige Änderungen, da ich nicht genau weiß, wie Ihr Modul aufgebaut ist, aber die Hauptideen sind da. Mit einigem Debuggen sollten Sie es zum Laufen bringen.
Hinweis: Der obige Code wurde mit Ultimate Module Creator v1.9 generiert .
Zumindest für Magento 1.9 muss sichergestellt sein, dass extJs geladen sind.
Wenden Sie eine der folgenden Methoden an, um die Verwendung von extJS im Backend zu aktivieren:
Verwenden Sie in Ihrem Controller Folgendes:
Verwenden Sie in Ihrem Layout-XML Folgendes:
