Question

我正在尝试将类别列添加到产品网格中。我修改了Mage_Adminhtml_Block_Catalog_Product_Grid。将以下内容添加到_prepareCollection：

->joinField('category_ids',
            'catalog/category_product_index',
            'category_id',
            'product_id=entity_id',
            null,
            'left')

这给了我一个错误： a:5:{i:0;s:72:"Item (Mage_Catalog_Model_Product) with the same id "16243" already exist"。

在prepareColumns中我添加：

$this->addColumn('category_ids',
        array(
            'header'=> Mage::helper('catalog')->__('Categories'),
            'index' => 'category_ids',
            'width' => '150px'
    ));

如何修复查询，以免出错？是否可以按类别名称而不是ID显示和过滤？

论坛帖子显示了类似的代码，但我无法使其与类别一起使用 http://www.magentocommerce.com/boards/viewthread/44534/

static protected $COLUMN_ID_TRADE_REFERENCES = 'ref_text';

protected function _prepareCollection()
{
    $store = $this->_getStore();
    $collection = Mage::getModel('catalog/product')->getCollection()
        ->addAttributeToSelect('name')
        ->addAttributeToSelect('attribute_set_id')
        ->addAttributeToSelect('type_id')
        ->addAttributeToSelect('ref_text')
        ->joinTable('productreferences/reference',
            'product_id=entity_id',
            array('ref_text'),
            null,
            'left')
        ->joinField('qty',
            'cataloginventory/stock_item',
            'qty',
            'product_id=entity_id',
            '{{table}}.stock_id=1',
            'left')
        ->addStaticField('ref_text')
        ->addExpressionAttributeToSelect(self::$COLUMN_ID_TRADE_REFERENCES,
            'GROUP_CONCAT(ref_text SEPARATOR " ; ")',
            'ref_text')
        ->groupByAttribute('entity_id');

Answer 1

根据上面的引用。

过滤器和可排序标志将阻止列标题可单击，并删除该列的过滤器文本框。由于我们已经做了一些繁重的解决方法来将类别列放入网格中，因此这些功能无论如何都不会起作用。我不需要它们，因此我没有考虑让它们工作有多难。

您需要做的就是粘贴下面的代码

    $collection = Mage::getModel('catalog/category')->getCollection()->addAttributeToSelect('name');
$options = array();
foreach ($collection as $item){
    if($item->getId() != ''){
    $options[$item->getId()] = $item->getName();
}
}

$this->addColumn('category_ids',
        array(
            'header'   => Mage::helper('catalog')->__('Categories'),
            'index'    => 'single_category_id',
            'width'    => '150px',
            'type' => 'options',
             'options'  => $options
));

取代

$this->addColumn('category_ids',
    array(
        'header'   => Mage::helper('catalog')->__('Categories'),
        'index'    => 'category_names',
        'width'    => '150px',
        'filter'   => false,
        'sortable' => false,

））;

Answer 2

如果您只想添加类别（不是类别路径），并且产品只有一个类别，请将其添加到集合设置中：

$collection->joinAttribute('catname','catalog_category/name','category_ids',null,'left');

Answer 3

显示您可以使用的所有类别的名称

$this->addColumn('category_ids',
        array(
                                    'header'=> Mage::helper('catalog')->__('Category'),
                                    'type'  => 'options',
                                    'index' => 'category_ids',
                                    'options' => $this->catOptions,
                                    'renderer'  => 'Your_Module_Block_Adminhtml_List_Cat',
));

在你的课程块中

 class Your_Module_Block_Adminhtml_List_Cat extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{
    public function render(Varien_Object $row)
    {
        $product = Mage::getModel('catalog/product')->load($row->getEntityId());
        $cats = $product->getCategoryIds();
        $allCats = '';
        foreach($cats as $key => $cat)
        {
            $_category = Mage::getModel('catalog/category')->load($cat);
            $allCats.= $_category->getName();
            if($key < count($cats)-1)
                $allCats.= ' ,';
        }
        return $allCats;
    }

}

我知道现在回答为时已晚，但最近我看到了这个问题，所以我也回答，因为它也可以帮助其他人。

参考此处：here

您必须创建一个扩展名才能在产品网格中显示类别。请创建以下文件，它将适合您：

在app/code/local/SoftProdigy/AdminGridCategoryFilter/Block/Catalog/Product/Grid/Render/Category.php位置创建新文件并添加以下代码：

<?php
class SoftProdigy_AdminGridCategoryFilter_Block_Catalog_Product_Grid_Render_Category extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{
    public function render(Varien_Object $row)
    {
        $product = Mage::getModel('catalog/product')->load($row->getEntityId());
        $cats = $product->getCategoryIds();
        $allCats = '';
        foreach($cats as $key => $cat)
        {
            $_category = Mage::getModel('catalog/category')->load($cat);
            $allCats.= $_category->getName();
            if($key < count($cats)-1)
                $allCats.= ',<br />';
        }
        return $allCats;
    }

}

在app/code/local/SoftProdigy/AdminGridCategoryFilter/etc/config.xml位置创建新文件并添加以下代码：

在app/code/local/SoftProdigy/AdminGridCategoryFilter/Helper/Data.php位置创建新文件并添加以下代码：

<?php
class SoftProdigy_AdminGridCategoryFilter_Helper_Data extends Mage_Core_Helper_Abstract
{

}

在app/code/local/SoftProdigy/AdminGridCategoryFilter/Model/Observer.php位置创建新文件并添加以下代码：

<?php

    public function addCategoryFilterToProductGrid(Varien_Event_Observer $observer)
    {   
        $block = $observer->getEvent()->getBlock();
        if( ($block instanceof Mage_Adminhtml_Block_Catalog_Product_Grid)  ) {
            $block->addColumnAfter('softprodigy_category_list', array(
                    'header'    => Mage::helper('admingridcategoryfilter')->__('Category'),
                    'index'     => 'softprodigy_category_list',
                    'sortable'  => false,
                    'width' => '250px',
                    'type'  => 'options',
                    'options'   => Mage::getSingleton('admingridcategoryfilter/system_config_source_category')->toOptionArray(),

    public function filterCallback($collection, $column)
    {
        $value = $column->getFilter()->getValue();
        $_category = Mage::getModel('catalog/category')->load($value);
        $collection->addCategoryFilter($_category);

        return $collection;
    }

}

在app/code/local/SoftProdigy/AdminGridCategoryFilter/Model/System/Config/Source/Category.php位置创建新文件并添加以下代码：

<?php

    public function toOptionArray($addEmpty = true)
    {
        $options = array();
        foreach ($this->load_tree() as $category) {
            $options[$category['value']] =  $category['label'];
        }

        return $options;
    }



    public function buildCategoriesMultiselectValues(Varien_Data_Tree_Node $node, $values, $level = 0)
    {
        $level++;

        $values[$node->getId()]['value'] =  $node->getId();
        $values[$node->getId()]['label'] = str_repeat("--", $level) . $node->getName();

        foreach ($node->getChildren() as $child)

        $parentId = $store ? Mage::app()->getStore($store)->getRootCategoryId() : 1;  // Current store root category

        $tree = Mage::getResourceSingleton('catalog/category_tree')->load();

        $root = $tree->getNodeById($parentId);

        if($root && $root->getId() == 1)
        {
            $root->setName(Mage::helper('catalog')->__('Root'));
        }

        $tree->addCollectionData($collection, true);

        return $this->buildCategoriesMultiselectValues($root, array());

现在从缓存管理中清除缓存，您可以在产品网格中看到类别列。
