Question

我正在尝试使用我的local.xml文件（我对布局进行所有更新）来删除嵌套在另一个块中的块。我可以通过＆lt; remove＆gt;轻松删除一个块标记，或使用unsetChild方法，但我似乎无法删除嵌套在另一个块中的块。

以下是我要删除的代码行（位于customer.xml文件中）。特别是，它是名为“customer_account_dashboard_newsletter”的块

<customer_account_index translate="label">
        <label>Customer My Account Dashboard</label>
        <update handle="customer_account"/>
        <!-- Mage_Customer -->
        <reference name="root">
            <action method="setTemplate"><template>page/2columns-left.phtml</template></action>
        </reference>
        <reference name="my.account.wrapper">
            <block type="customer/account_dashboard" name="customer_account_dashboard" template="customer/account/dashboard.phtml">
                <block type="customer/account_dashboard_hello" name="customer_account_dashboard_hello" as="hello" template="customer/account/dashboard/hello.phtml"/>
                <block type="core/template" name="customer_account_dashboard_top" as="top" />
                <block type="customer/account_dashboard_info" name="customer_account_dashboard_info" as="info" template="customer/account/dashboard/info.phtml"/>
                <block type="customer/account_dashboard_newsletter" name="customer_account_dashboard_newsletter" as="newsletter" template="customer/account/dashboard/newsletter.phtml"/>
                <block type="customer/account_dashboard_address" name="customer_account_dashboard_address" as="address" template="customer/account/dashboard/address.phtml"/>
                <block type="core/template" name="customer_account_dashboard_info1" as="info1" />
                <block type="core/template" name="customer_account_dashboard_info2" as="info2" />
            </block>
        </reference>

    </customer_account_index>

我意识到这现在不起作用，但这是我的起点（位于我的local.xml文件中）：

<customer_account_index>
    <reference name="my.account.wrapper">
            <action method="unsetChild"><name>customer_account_dashboard_newsletter</name></action>
    </reference>
</customer_account_index>

有什么想法？谢谢。

Answer 1

我认为你引用了错误的块。您必须引用要删除的块的父块。您正在引用父级的父块。

<customer_account_index>
  <reference name="customer_account_dashboard">
    <action method="unsetChild"><name>customer_account_dashboard_newsletter</name></action>
  </reference>
</customer_account_index>

Answer 2

要在另一个块中取消设置块，您必须嵌套引用。例如：

<catalog_product_view>
    <reference name="content">
        <reference name="product.info">
            <action method="unsetChild"><name>addtocart</name></action>
        </reference>
    </reference>
</catalog_product_view>

此外，有时系统无法识别块名称，因此您必须在操作中使用别名。

Answer 3

通常，如果要删除嵌套块，还应该在local.xml中嵌套引用，在您的情况下，正确的语法将是：

<customer_account_index>
    <reference name="my.account.wrapper">
        <reference name="customer_account_dashboard">
            <remove name="customer_account_dashboard_newsletter" />
        </reference>
    </reference>
</customer_account_index>

但我注意到customer.xml

中的以下行

<block type="customer/account_dashboard_newsletter" name="customer_account_dashboard_newsletter" as="newsletter" template="customer/account/dashboard/newsletter.phtml"/>

没有显示要删除的块的效果。但是该块会添加到customer/account/dashboard/info.phtml模板中，该模板包含在customer.xml中的上一行中：

<block type="customer/account_dashboard_info" name="customer_account_dashboard_info" as="info" template="customer/account/dashboard/info.phtml"/>

如果您将customer/account/dashboard/info.phtml复制到主题，则可以删除在信息中心上显示简报拦截的代码：

<?php if( $this->isNewsletterEnabled() ): ?>

Answer 4

要从Customer DashBoard中删除Newsletter块，您必须修改文件

应用程序/前端/ yourtemplate /模板/客户/帐户/仪表板/ info.phtml

并删除此代码块

<?php if( $this->isNewsletterEnabled() ): ?>
<div class="col-2">
    <div class="box">
        <div class="box-title">
            <h3><?php echo $this->__('Newsletters') ?></h3>
            <a href="<?php echo $this->getUrl('newsletter/manage') ?>"><?php echo $this->__('Edit') ?></a>
        </div>
        <div class="box-content">
            <p>
                <?php if( $this->getIsSubscribed() ): ?>
                    <?php echo $this->__("You are currently subscribed to 'General Subscription'.") ?>
                <?php else: ?>
                    <?php echo $this->__('You are currently not subscribed to any newsletter.') ?>
                <?php endif; ?>
            </p>
        </div>
    </div>
    <?php /* Extensions placeholder */ ?>
    <?php echo $this->getChildHtml('customer.account.dashboard.info.extra')?>
</div>
<?php endif; ?>
