我已經爲此問題添加了答案。 Implement multiple product chooser widget Magento
我檢查了https://github.com/dio5/magento-multiproducts-widget下的模塊。
使用FORK選項而不是下載ZIP。
它的工作原理和給出了精確的結果，例如WIDGET中的多種產品選擇。如果有任何錯誤，請告訴我。
讓我知道，如果這對你有用。
謝謝！
[編輯我以前的評論，在代碼的請求，在這裏直接]

/命名空間/模塊名/座/Adminhtml/Catalog/Product/MultiProducts/Chooser.php
Thi s功能將調用DOCHOOSE（）功能，這將有助於「選擇」選中/選擇的產品。
/**
* prepare layout for products grid
*
* @return type Mage_Adminhtml_Block_Catalog_Product_Widget_Chooser
*/
protected function _prepareLayout()
{
$this->setChild('choose_button', $this->getLayout()->createBlock('adminhtml/widget_button')
->setData(array(
'label' => Mage::helper('adminhtml')->__('Choose Selected Products'),
'onclick' => $this->getJsObjectName() . '.doChoose()'
))
);
return parent::_prepareLayout();
}
的下面功能需要被用於製備產物元素的HTML，格式爲{1} {2}
/**
* Prepare chooser element HTML
*
* @param Varien_Data_Form_Element_Abstract $element Form Element
* @return Varien_Data_Form_Element_Abstract
*/
public function prepareElementHtml(Varien_Data_Form_Element_Abstract $element)
{
$uniqueId = Mage::helper('core')->uniqHash($element->getId());
$sourceUrl = $this->getUrl('*/multiproducts/chooser', array(
'uniq_id' => $uniqueId,
'use_massaction' => true,
));
$chooser = $this->getLayout()->createBlock('widget/adminhtml_widget_chooser')
->setElement($element)
->setTranslationHelper($this->getTranslationHelper())
->setConfig($this->getConfig())
->setFieldsetId($this->getFieldsetId())
->setSourceUrl($sourceUrl)
->setUniqId($uniqueId);
if ($element->getValue())
{
$label = "";
$ids = explode('}{', $element->getValue());
$cleanIds = array();
foreach ($ids as $id)
{
$id = str_replace('{', '', $id);
$id = str_replace('}', '', $id);
$cleanIds[] = $id;
}
$products = $this->_getProductsByIDs($cleanIds);
if ($products)
{
$label .= '<ul>';
foreach ($products as $product)
{
$label .= '<li>' . $product->getName() . '</li>';
}
$label .= '</ul>';
$chooser->setLabel($label);
}
}
$element->setData('after_element_html', $chooser->toHtml());
return $element;
}
JS爲複選框選中/取消
/**
* Checkbox Check JS Callback
*
* @return string
*/
public function getCheckboxCheckCallback()
{
if ($this->getUseMassaction())
{
return "function (grid, element) {
$(grid.containerId).fire('product:changed', {element: element});
}";
}
}
JS行/產品點擊/選中/選中
/**
* Grid Row JS Callback
*
* @return string
*/
public function getRowClickCallback()
{
if (!$this->getUseMassaction())
{
$chooserJsObject = $this->getId();
return '
function (grid, event) {
var trElement = Event.findElement(event, "tr");
var productId = trElement.down("td").innerHTML;
var productName = trElement.down("td").next().next().innerHTML;
var optionLabel = productName;
var optionValue = "product/" + productId.replace(/^\s+|\s+$/g,"");
if (grid.categoryId) {
optionValue += "/" + grid.categoryId;
}
if (grid.categoryName) {
optionLabel = grid.categoryName + "/" + optionLabel;
}
' . $chooserJsObject . '.setElementValue(optionValue);
' . $chooserJsObject . '.setElementLabel(optionLabel);
' . $chooserJsObject . '.close();
}
';
}
}
JS代碼，如果用戶有興趣從特定類別中選擇產品。
/**
* Category Tree node onClick listener js function
*
* @return string
*/
public function getCategoryClickListenerJs()
{
$js = '
function (node, e) {
{jsObject}.addVarToUrl("category_id", node.attributes.id);
{jsObject}.reload({jsObject}.url);
{jsObject}.categoryId = node.attributes.id != "none" ? node.attributes.id : false;
{jsObject}.categoryName = node.attributes.id != "none" ? node.text : false;
}
';
$js = str_replace('{jsObject}', $this->getJsObjectName(), $js);
return $js;
}
用於準備帶產品ID的POST元素的附加JS。
/**
* return additional JS for controls
*
* @return JS
*/
public function getAdditionalJavascript()
{
$chooserJsObject = $this->getId();
$js = '
{jsObject}.initChecked = function() {
$$("#' . $chooserJsObject . '_table tbody input:checkbox").each(function(element, i) {
var values = ' . $chooserJsObject . '.getElementValue();
var capture = values.replace("{"+element.value+"}", "match");
var searchValue = "match";
if(capture.search(searchValue) != -1)
{
element.checked = true;
}
});
}
{jsObject}.initChecked();
var values = ' . $chooserJsObject . '.getElementValue();
$("' . $chooserJsObject . '").insert({bottom: "<div class=\"filter\"><input type=\"hidden\" value=\"+values+\" name=\"selected_products\" /></div>"});
$$("#' . $chooserJsObject . '_table tbody input:checkbox").invoke("observe", "change", function(event) {
var element = Event.element(event);
var label = element.up("td").next().next().next().innerHTML;
label = label.replace(/^\s\s*/, "").replace(/\s\s*$/, "");
if(element.checked)
{
{jsObject}.addValue(element.value);
{jsObject}.addLabel(label);
} else {
{jsObject}.removeValue(element.value);
{jsObject}.removeLabel(label);
}
});
{jsObject}.removeValue = function(value) {
var currentValue = ' . $chooserJsObject . '.getElementValue();
currentValue = currentValue.replace("{"+value+"}", "");
' . $chooserJsObject . '.setElementValue(currentValue);
}
{jsObject}.addValue = function(value) {
var currentValue = ' . $chooserJsObject . '.getElementValue();
currentValue = currentValue.replace("{"+value+"}", "");
currentValue = currentValue + "{"+value+"}";
' . $chooserJsObject . '.setElementValue(currentValue);
}
{jsObject}.removeLabel = function(label) {
var currentLabel = ' . $chooserJsObject . '.getElementLabelText();
currentLabel = currentLabel.replace("<li>"+label+"</li>", "");
' . $chooserJsObject . '.setElementLabel(currentLabel);
}
{jsObject}.addLabel = function(label) {
var currentLabel = ' . $chooserJsObject . '.getElementLabelText();
if(currentLabel.search("ul") != -1)
{
currentLabel = currentLabel.replace("</ul>", "");
currentLabel = currentLabel.replace("<li>"+label+"</li>", "");
} else {
currentLabel = "<ul>";
}
currentLabel = currentLabel +"<li>"+label+"</li></ul>";
' . $chooserJsObject . '.setElementLabel(currentLabel);
}
{jsObject}.doChoose = function(node,e) {
' . $chooserJsObject . '.close();
}
';
$js = str_replace('{jsObject}', $this->getJsObjectName(), $js);
return $js;
}
以上是主要功能，它將幫助您在彈出窗口中從GRID中選擇多個產品。
還有更多的可以在這裏檢查一下代碼：https://github.com/dio5/magento-multiproducts-widget
步驟：
- 導航到一個CMS頁面的管理面板
- 點擊「插入控件」在所見即所得編輯器
- 選擇小工具類型 - 目錄多個產品小工具
- 輸入標題，產品計數
- 選擇一個模板（可以添加所需的一種選擇，因爲許多模板）
- 點擊「選擇產品」按鈕，從電網
- 選擇產品
- 點擊「選擇選用產品」按鈕
希望這可以幫助別人！
編碼快樂......
很好的問題+1爲 –
