Question

也许它很简单，但我对php不太好使用此代码，我可以加载Magento中类别顶部样式的静态块和顶部类别具有子项时底部的子类别我想要做的是，当没有子类别时，它应该只加载块
否则因为造型会占据子猫所处的位置。请查看我的代码，也许您了解：

<?php
    $_helper    = $this->helper('catalog/output');
    $_category  = $this->getCurrentCategory();
    $_imgHtml   = '';
    if ($_imgUrl = $_category->getImageUrl()) {
        $_imgHtml = '<div class="category-image"><img src="'.$_imgUrl.'" alt="'.$this->htmlEscape($_category->getName()).'" title="'.$this->htmlEscape($_category->getName()).'" /></div>';
        $_imgHtml = $_helper->categoryAttribute($_category, $_imgHtml, 'image');
    }
    $_catHtml = $this->getChildHtml('catalog.inline.subcat');
?>
<?php if (!Mage::registry('current_category')) return ?>
<?php $_categories = $this->getCurrentChildCategories() ?>
<?php $_count = is_array($_categories)?count($_categories):$_categories->count(); ?>
<?php if($_count): ?>

// load the blocks styled with ul and il backgrounds 

                <ul class="inline-categories"> 
                <?php echo $this->getLayout()->createBlock('cms/block')->setBlockId(   $this->getCurrentCategory()->getLandingPage()    )->toHtml() ?> 
                <?php foreach ($_categories as $_category): ?>
                <li<?php if($_i == 1):?> class="first"<?php endif ?>><a href="<?php echo $this->getCategoryUrl($_category) ?>"<?php if ($this->isCategoryActive($_category)): ?> class="current"<?php endif; ?>>    
                <?php echo $this->htmlEscape($_category->getName()) ?></a> (<?php echo $_category->getProductCount() ?>)</li>
                <?php endforeach ?> 
                <?php endif; ?>     
                </ul>

                // here i need something like an "else" because the if($count) allready understand that this is not on count so should only load this that is without style //

               <?php echo $this->getLayout()->createBlock('cms/block')->setBlockId(   $this->getCurrentCategory()->getLandingPage()    )->toHtml() ?> 

                //end of this else thing, now should only load the cms/block alone without anything / end of page we are done...

您可以使用PHP的if / else语句，如下所示：

<?php if ($_count): ?>

    stuff if $_count is non-zero

<?php else: ?>

    other stuff if $_count is zero

<?php endif; ?>

Magento PHP if语句“加载两个块”，否则只加载一个？
