magento的产品列表页面（类别view.phtml / product list.phtml）中的getChildHtml（）方法不起作用

Question

我在getToolbarHtml（）之后在list.phtml文件中调用我新创建的引用。 但是它什么也没显示。 我的catalog.xml文件如下所示：

<reference name="content">
            <block type="catalog/category_view" name="category.products" template="catalog/category/view.phtml">
                <block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml">
                    <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml">
                        <block type="page/html_pager" name="product_list_toolbar_pager"/>

                        <!-- The following code shows how to set your own pager increments -->
                        <!--
                            <action method="setDefaultListPerPage"><limit>4</limit></action>
                            <action method="setDefaultGridPerPage"><limit>9</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>2</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>4</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>6</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>8</limit></action>
                            <action method="addPagerLimit" translate="label"><mode>list</mode><limit>all</limit><label>All</label></action>
                        -->
                    </block>
                    <reference name="newreference">
                        <block type="core/template" name="newreferenceblock" template="newreference.phtml" />
                    </reference>

                    <action method="addColumnCountLayoutDepend"><layout>empty</layout><count>6</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>one_column</layout><count>5</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>two_columns_left</layout><count>4</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>two_columns_right</layout><count>4</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>three_columns</layout><count>3</count></action>
                    <action method="setToolbarBlockName"><name>product_list_toolbar</name></action>

                </block>
                    </block>

我在引用内部调用引用，问题是我想创建自己的侧边栏。 那么，这有什么问题呢？ 在list.phtml中，我通过以下方式致电我的参考：

<?php echo $this->getChildHtml('newreference') ?>

请帮我。

Answer 1

请使用以下方法（记住要在内容下的catelog.xml中更新您的xml）：

<?php echo $this->getLayout()->getBlock('yourblockname')->toHtml(); ?> 

Answer 2

更换：

<reference name="newreference">
    <block type="core/template" name="newreferenceblock" template="newreference.phtml" />
</reference>

与：

<block type="core/template" name="newreferenceblock" template="newreference.phtml" />

然后使用“ newreferenceblock”作为模块名称在模板中调用您的模块：

<?php echo $this->getChildHtml('newreferenceblock') ?>

Answer 3

将您的newreference块放在内容块的外面。

<?php echo $this->getChildHtml('newreference') ?> call this block in one of your layout file something like below its for 2columns-right layout

<div class="main-container col2-right-layout">
        <div class="main">
            <?php echo $this->getChildHtml('breadcrumbs') ?>
            <div class="col-main">
                <?php echo $this->getChildHtml('global_messages') ?>
                <?php echo $this->getChildHtml('content') ?>
            </div>
            <div class="col-right sidebar"><?php echo $this->getChildHtml('right') ?></div>
        </div>
        <div><?php echo $this->getChildHtml('newreference') ?></div>
    </div>

<reference name="content">
            <block type="catalog/category_view" name="category.products" template="catalog/category/view.phtml">
                <block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml">

                     <block type="core/text_list" name="left_custompage" as="left_custompage">
                        <block type="catalog/navigation" name="catalog.leftnav" after="currency" template="catalog/navigation/left.phtml"/>
                     </block>
                    <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml">
                        <block type="page/html_pager" name="product_list_toolbar_pager"/>
                        <!-- The following code shows how to set your own pager increments -->
                        <!--
                            <action method="setDefaultListPerPage"><limit>10</limit></action>
                            <action method="setDefaultGridPerPage"><limit>8</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>10</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>20</limit></action>
                            <action method="addPagerLimit"><mode>list</mode><limit>30</limit></action>
                            <action method="addPagerLimit" translate="label"><mode>list</mode><limit>all</limit><label>All</label></action>
                            <action method="addPagerLimit"><mode>grid</mode><limit>8</limit></action>
                            <action method="addPagerLimit"><mode>grid</mode><limit>16</limit></action>
                            <action method="addPagerLimit"><mode>grid</mode><limit>24</limit></action>
                            <action method="addPagerLimit" translate="label"><mode>grid</mode><limit>all</limit><label>All</label></action>
                        -->
                    </block>
                    <action method="addColumnCountLayoutDepend"><layout>empty</layout><count>6</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>one_column</layout><count>5</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>two_columns_left</layout><count>4</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>two_columns_right</layout><count>4</count></action>
                    <action method="addColumnCountLayoutDepend"><layout>three_columns</layout><count>3</count></action>
                    <action method="setToolbarBlockName"><name>product_list_toolbar</name></action>
                </block>
            </block>

其中custompage是我的自定义块，我将其用作侧边栏。
