Question

我正在开发一个自定义模板，而且我必须修改组件的帮助源代码。为了防止这种情况，我想知道是否有相应的方法来扩展某个组件的特定辅助类具有自己的功能，或者覆盖它？

在我的自定义模板jmlroot/templates/mytemplate/html/com_hikashop/product/listing_div.php中引入覆盖文件：

<form action="<?php echo hikashop_currentURL(); ?>" method="post" name="adminForm_<?php echo $this->params->get('main_div_name').$this->category_selected;?>_bottom">
    <div class="hikashop_products_pagination hikashop_products_pagination_bottom">
    <?php echo $this->pagination->getListFooter($this->params->get('limit')); ?>
    <span class="hikashop_results_counter"><?php echo $this->pagination->getResultsCounter(); ?></span>
    </div>
    <input type="hidden" name="filter_order_<?php echo $this->params->get('main_div_name').$this->category_selected;?>" value="<?php echo $this->pageInfo->filter->order->value; ?>" />
    <input type="hidden" name="filter_order_Dir_<?php echo $this->params->get('main_div_name').$this->category_selected;?>" value="<?php echo $this->pageInfo->filter->order->dir; ?>" />
    <?php echo JHTML::_( 'form.token' ); ?>
</form>

在该表单中有一个PHP代码：

<?php echo $this->pagination->getListFooter($this->params->get('limit')); ?>

从帮助文件jmlroot/administrator/components/com_hikashop/helpers/pagination.php调用的内容：

class hikashopPaginationHelper extends hikashopBridgePaginationHelper{
    function _item_active(JPaginationObject $item){
        $class = 'pagenav';
        $specials = array('start','end','previous','next');
        foreach($specials as $special){
            if(!empty($item->$special)){
                $class.=' hikashop_'.$special.'_link';
            }
        }
        if($item->base>0)
            return "<a class=\"".$class."\" title=\"".$item->text."\" onclick=\"javascript: document.adminForm".$this->hikaSuffix.$this->form.".limitstart".$this->hikaSuffix.".value=".$item->base."; document.adminForm".$this->hikaSuffix.$this->form.".submit();return false;\">".$item->text."</a>";
        else
            return "<a class=\"".$class."\" title=\"".$item->text."\" onclick=\"javascript: document.adminForm".$this->hikaSuffix.$this->form.".limitstart".$this->hikaSuffix.".value=0; document.adminForm".$this->hikaSuffix.$this->form.".submit();return false;\">".$item->text."</a>";
    }
    function _item_inactive(JPaginationObject $item){
        $mainframe = JFactory::getApplication();
        if ($mainframe->isAdmin()) {
            return "<span>".$item->text."</span>";
        } else {
            $class = 'pagenav';
            if(!is_numeric($item->text)){
                $class .= ' pagenav_text';
            }
            return '<span class="'.$class.'">'.$item->text."</span>";
        }
    }
}

我需要使用一点修改后的代码覆盖该类hikashopPaginationHelper（通过<spans />重新填充<li/>。

我尝试将这部分代码添加到文件大小的jmlroot/templates/mytemplate/html/com_hikashop/product/listing_div.php中：

jimport('joomla.application.component.controller');
jimport('joomla.html.pagination');

require_once JPATH_ADMINISTRATOR . '/components/com_hikashop/helpers/pagination.php';

class MY_hikashopPaginationHelper extends hikashopBridgePaginationHelper{
    function _item_active(JPaginationObject $item){
        $class = 'pagenav';
        $specials = array('start','end','previous','next');
        foreach($specials as $special){
            if(!empty($item->$special)){
                $class.=' hikashop_'.$special.'_link';
            }
        }
        if($item->base>0)
            return "<li><a class=\"".$class."\" title=\"".$item->text."\" onclick=\"javascript: document.adminForm".$this->hikaSuffix.$this->form.".limitstart".$this->hikaSuffix.".value=".$item->base."; document.adminForm".$this->hikaSuffix.$this->form.".submit();return false;\">".$item->text."</a></li>";
        else
            return "<li><a class=\"".$class."\" title=\"".$item->text."\" onclick=\"javascript: document.adminForm".$this->hikaSuffix.$this->form.".limitstart".$this->hikaSuffix.".value=0; document.adminForm".$this->hikaSuffix.$this->form.".submit();return false;\">".$item->text."</a></li>";
    }
    function _item_inactive(JPaginationObject $item){
        $mainframe = JFactory::getApplication();
        if ($mainframe->isAdmin()) {
            return "<li>".$item->text."</li>";
        } else {
            $class = 'pagenav';
            if(!is_numeric($item->text)){
                $class .= ' pagenav_text';
            }
            return '<li class="'.$class.'">'.$item->text."</li>";
        }
    }
}

但它没有帮助。我认为我做错了什么，有人评论过什么？
