我想创建一个前一个下一个按钮,用于从特定类别中的一个产品移动到另一个产品。
我在view.phtml中使用此代码,但现在它为$ search_parameter提供了未定义的变量错误。
<?php // Previous and Next product links in product page
$_product = $this->getProduct();
if(!$_product->getCategoryIds())
return; // Don't show Previous and Next if product is not in any category
$cat_ids = $_product->getCategoryIds(); // get all categories where the product is located
$cat = Mage::getModel('catalog/category')->load( $cat_ids[0] ); // load first category, you should enhance this, it works for me
$order = Mage::getStoreConfig('catalog/frontend/default_sort_by');
$direction = 'asc'; // asc or desc
$category_products = $cat->getProductCollection()->addAttributeToSort($order, $direction);
$category_products->addAttributeToFilter('status',1); // 1 or 2
$category_products->addAttributeToFilter('visibility',4); // 1.2.3.4
$cat_prod_ids = $category_products->getAllIds(); // get all products from the category
$_product_id = $_product->getId();
$_pos = array_search($_product_id, $cat_prod_ids); // get position of current product
$_next_pos = $_pos+1;
$_prev_pos = $_pos-1;
// get the next product url
if( isset($cat_prod_ids[$_next_pos]) ) {
$_next_prod = Mage::getModel('catalog/product')->load( $cat_prod_ids[$_next_pos] );
} else {
$_next_prod = Mage::getModel('catalog/product')->load( reset($cat_prod_ids) );
}
// get the previous product url
if( isset($cat_prod_ids[$_prev_pos]) ) {
$_prev_prod = Mage::getModel('catalog/product')->load( $cat_prod_ids[$_prev_pos] );
} else {
$_prev_prod = Mage::getModel('catalog/product')->load( end($cat_prod_ids) );
}
?>
<div class="clear"></div>
<!--PREVIOUS BUTTON NEXT BUTTON STARTS-->
<div class="previousNext">
<?php if($_prev_prod != NULL): ?>
<a href="<?php print $_prev_prod->getUrlPath(); if($search_parameter):?>?search=1<?php endif;?>"><span style="margin-right: 270px;"><?php echo $this->__('<< PREVIOUS') ?></span></a>
<?php endif; ?>
<?php if($_next_prod != NULL): ?>
<a href="<?php print $_next_prod->getUrlPath(); if($search_parameter):?>?search=1<?php endif;?>"><span style="margin-left: 270px;"><?php echo $this->__('NEXT >>') ?></span></a>
<?php endif; ?>
</div>
<!--PREVIOUS BUTTON NEXT BUTTON ENDS-->
<div class="clear"></div>
答案 0 :(得分:-2)
以下是以下步骤:
第1步:添加产品时确保每个产品仅添加到ONE CATEGORY。一个产品在多个类别中,此代码不起作用。换句话说,如果您要添加产品说Cat1&gt; Subcat1&gt; subsubcat2,确保只将它添加到subsubcat2。你可以在那个子子猫中移动下一个。
第2步:打开view.phtml并添加以下代码:
<?php // Previous and Next product links in product page
$_product = $this->getProduct();
if(!$_product->getCategoryIds())
return; // Don't show Previous and Next if product is not in any category
$cat_ids = $_product->getCategoryIds(); // get all categories where the product is located
$cat = Mage::getModel('catalog/category')->load( $cat_ids[0] ); // load first category, you should enhance this, it works for me
$order = Mage::getStoreConfig('catalog/frontend/default_sort_by');
$direction = 'desc'; // asc or desc
$category_products = $cat->getProductCollection()->addAttributeToSort($order, $direction);
$category_products->addAttributeToFilter('status',1); // 1 or 2
$category_products->addAttributeToFilter('visibility',4); // 1.2.3.4
$cat_prod_ids = $category_products->getAllIds(); // get all products from the category
$_product_id = $_product->getId();
$_pos = array_search($_product_id, $cat_prod_ids); // get position of current product
$_next_pos = $_pos+1;
$_prev_pos = $_pos-1;
// get the next product url
if( isset($cat_prod_ids[$_next_pos]) ) {
$_next_prod = Mage::getModel('catalog/product')->load( $cat_prod_ids[$_next_pos] );
} else {
$_next_prod = Mage::getModel('catalog/product')->load( reset($cat_prod_ids) );
}
// get the previous product url
if( isset($cat_prod_ids[$_prev_pos]) ) {
$_prev_prod = Mage::getModel('catalog/product')->load( $cat_prod_ids[$_prev_pos] );
} else {
$_prev_prod = Mage::getModel('catalog/product')->load( end($cat_prod_ids) );
}
?>
第3步:添加PREVIOS和NEXT按钮代码
<!--PREVIOUS BUTTON NEXT BUTTON STARTS-->
<div class="previousNext">
<?php if($_prev_prod != NULL): ?>
<a href="<?php print $_prev_prod->getUrlPath();?>"><span style="margin-right: 270px;"><?php echo $this->__('<< PREVIOUS') ?></span></a>
<?php endif; ?>
<?php if($_next_prod != NULL): ?>
<a href="<?php print $_next_prod->getUrlPath();?>"><span style="margin-left: 270px;"><?php echo $this->__('NEXT >>') ?></span></a>
<?php endif; ?>
</div>
<!--PREVIOUS BUTTON NEXT BUTTON ENDS-->
第4步:将css样式添加到链接
<style>
.previousNext {width: 100%; height: 20px; text-align: right; }
.previousNext a:link {font-size: 12px; color:#ffffff; font-weight: bold; text-decoration: none}
.previousNext a:visited {font-size: 12px; color:#ffffff; font-weight: bold; text-decoration: none}
.previousNext a:hover {font-size: 12px; color:#ff9900; font-weight: bold; text-decoration: underline}
.previousNext a:active {font-size: 12px; color:#ffffff; font-weight: bold; text-decoration: none}
</style>
将以前的下一个按钮理想地放在product-essential div(默认模板)
中你的下一个或上一个项目已做好准备工作......
希望这会有所帮助......
