Kategoriebaum in benutzerdefinierte Erweiterung hinzufügen

Question

Ich versuche, die kundenspezifische Erweiterung der Kategorie hinzuzufügen, die Kategoriebaum, die sich auf einer der Registerkarten der Produktseite bearbeiten

Answer 1

Bereiten Sie sich vor, das wird lang. Hier geht.
Sie benötigen die folgenden Dateien:

app/code/local/[Namespace]/[Module]/Block/Adminhtml/[Entity]/Edit/Tab/Categories.php - Die Registerkarte, die die Kategorien rendert.

<?php
class [Namespace]_[Module]_Block_Adminhtml_[Entity]_Edit_Tab_Categories
    extends Mage_Adminhtml_Block_Catalog_Category_Tree {
    protected $_categoryIds = null;
    protected $_selectedNodes = null;
    public function __construct() {
        parent::__construct();
        $this->setTemplate('[namespace]_module/[entity]/edit/tab/categories.phtml');
        $this->_withProductCount = false;
    }
    public function get[Entity](){
        return Mage::registry('current_[entity]'); //use other registration key if you have one
    }

    public function getCategoryIds(){
        if (is_null($this->_categoryIds)){
            $categories = $this->get[Entity]()->getSelectedCategories();
                $ids = array();
                foreach ($categories as $category){
                    $ids[] = $category->getId();
                }
                $this->_categoryIds = $ids;
        }
        return $this->_categoryIds;
    }
    public function getIdsString(){
        return implode(',', $this->getCategoryIds());
    }
    public function getRootNode(){
        $root = $this->getRoot();
        if ($root && in_array($root->getId(), $this->getCategoryIds())) {
            $root->setChecked(true);
        }
        return $root;
    }

        }

            $selectedCategoryIds = $this->getCategoryIds();
            $allChildrenArr = explode(',', $allChildren);
            for ($i = 0, $cnt = count($selectedCategoryIds); $i < $cnt; $i++) {
                $isSelf = $node->getId() == $selectedCategoryIds[$i];

        return $result;
    }
    protected function _getSelectedNodes(){
        if ($this->_selectedNodes === null) {
            $this->_selectedNodes = array();
            $root = $this->getRoot();
            foreach ($this->getCategoryIds() as $categoryId) {
                if ($root) {
                    $this->_selectedNodes[] = $root->getTree()->getNodeById($categoryId);
                }

        }
        $children = array();
        foreach ($node->getChildren() as $child) {
            $children[] = $this->_getNodeJson($child);
        }
        return Mage::helper('core')->jsonEncode($children);
    }
    public function getLoadTreeUrl($expanded = null){
        return $this->getUrl('*/*/categoriesJson', array('_current' => true));
    }
    public function getSelectedCategoryPathIds($rootId = false){
        $ids = array();
        $categoryIds = $this->getCategoryIds();
        if (empty($categoryIds)) {
            return array();
        }
        $collection = Mage::getResourceModel('catalog/category_collection');

            $collection->addFieldToFilter('parent_id', $rootId);
        }
        else {

            }
        }
        return $ids;
    }
}

app/design/adminhtml/default/default/[namespace]_[module]/[entity]/tab/edit/categories.phtml - Die Vorlage, die erforderlich ist, um die Kategorien zu rendern

        }

    }
</script>
<?php endif; ?>

In Ihrer Formulardatei, in der Sie die Registerkarten Ihrer benutzerdefinierten Entität hinzufügen, fügen Sie dies auch 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 Diese beiden Aktionen, die die Anfragen für Kategorien bearbeiten:

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 im selben 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 -Layoutdatei Ihres Moduls dieses Handle für die Kategorienaktion 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>

Gehen wir nun mit dem Speichern Ihrer Daten fort.
Dazu benötigen Sie Folgendes in einem der Install-/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 das hinzu config.xml im Inneren <[module]_resource><entities> Schild

<[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 Sammelressourcenmodell: 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 Savaction Ihres Administratorcontrollers direkt vor dem Aufrufen hinzu $[entity]->save()

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

In Ihrem Entitätsmodell fügen Sie dies ganz oben in Ihrer Klasse hinzu: protected $_categoryInstance = null; und diese Methoden überall:

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 erforderte möglicherweise einige Änderungen, da ich nicht weiß, wie genau Ihr Modul erstellt wird, aber die Hauptideen sind da. Mit einigem Debuggen sollten Sie es zum Laufen bringen.

Answer 2

Zumindest für Magento 1.9 müssen Sie sicher sein, dass EXTJS geladen ist.
Verwenden Sie eine der folgenden Methoden, um die Verwendung von ExtJs im Backend zu aktivieren:

1. Verwenden Sie dies in Ihrem Controller:

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

2. Verwenden Sie in Ihrem Layout XML Folgendes:

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