Joomla如何使到类别的链接起作用

Question

我在 mytemplate/html/com_content/featured/default.php 中有以下代码

<?php if (!empty($this->lead_items)) : ?>
    <div class="<?php echo $this->pageclass_sfx;?>">
<div class="block-head">
        <h2><?php echo $this->escape($this->params->get('page_heading')); ?></h2>
        <a href="<?php echo JRoute::_(ContentHelperRoute::getCategoryRoute($this->item->catslug)); ?>" class="more">all news</a>
    </div><!-- .block-head -->
<?php foreach ($this->lead_items as &$item) : ?>
    <dl>
        <dt>
        <?php 
            $params = JComponentHelper::getParams( 'com_content' );
            $this->item = &$item;
            $images = json_decode($item->images);
        ?>  
        <?php  if (isset($images->image_intro) and !empty($images->image_intro)) : ?>
            <?php $imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro; ?>
                    <a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>" class="img-intro-<?php echo htmlspecialchars($imgfloat); ?>">
                    <img <?php if ($images->image_intro_caption):
                    echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
                endif; ?>
                src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/>
            </a>
        <?php endif; ?>
        </dt>
        <dd>
            <var class="date"><?php echo JHtml::_('date', $this->item->publish_up, JText::_('DATE_FORMAT_LC')); ?></var>
            <h3><a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>" class="<?php if($this->params->get('page_heading') == 'projects'){echo 'more';}; ?>"><?php echo $this->item->title; ?></a></h3>
            <?php echo $this->item->introtext; ?>
            <div class="news-link clearfix">
                <a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>" class="more"><?php  echo JText::sprintf('COM_CONTENT_READ_MORE_TITLE'); ?></a>
                <div class="line"></div>
            </div>
        </dd>
    <?php
        $leadingcount++;
    ?>
    </dl>
<?php endforeach; ?>

一切正常，除了类别新闻的链接。这里是：

<a href="<?php echo JRoute::_(ContentHelperRoute::getCategoryRoute($this->item->catslug)); ?>" class="more">all news</a>

如何让它发挥作用？

谢谢。

感谢洛德的帮助。我使用了你的代码，只是添加了中断

<div class="block-head">
    <h2><?php echo $this->escape($this->params->get('page_heading')); ?></h2>
    <?php foreach ($this->lead_items as &$item) :
          $this->item = &$item;
          $title = $this->escape($this->item->category_title);
          echo '<a href="'.JRoute::_(ContentHelperRoute::getCategoryRoute($this->item->catid, $this->item->catid)).'" class="more">all '.$title.'</a>';
          break;
     endforeach; ?>
</div><!-- .block-head -->

完整的解决方案

<div class="block-head">
    <h2><?php echo $this->escape($this->params->get('page_heading')); ?></h2>
    <?php foreach ($this->lead_items as &$item) :
          $this->item = &$item;
          $title = $this->escape($this->item->category_title);
          echo '<a href="'.JRoute::_(ContentHelperRoute::getCategoryRoute($this->item->catid, $this->item->catid)).'" class="more">all '.$title.'</a>';
          break;
     endforeach; ?>
</div>
<?php foreach ($this->lead_items as &$item) : ?>
    <dl>
        <dt>
        <?php 
            $params = JComponentHelper::getParams( 'com_content' );
            $this->item = &$item;
            $images = json_decode($item->images);
        ?>  
        <?php  if (isset($images->image_intro) and !empty($images->image_intro)) : ?>
            <?php $imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro; ?>
                    <a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>" class="img-intro-<?php echo htmlspecialchars($imgfloat); ?>">
                    <img <?php if ($images->image_intro_caption):
                    echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
                endif; ?>
                src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/>
            </a>
        <?php endif; ?>
        </dt>
        <dd>
            <var class="date"><?php echo JHtml::_('date', $this->item->publish_up, JText::_('DATE_FORMAT_LC')); ?></var>
            <h3><a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>" class="<?php if($this->params->get('page_heading') == 'projects'){echo 'more';}; ?>"><?php echo $this->item->title; ?></a></h3>
            <?php echo $this->item->introtext; ?>
            <div class="news-link clearfix">
                <a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>" class="more"><?php  echo JText::sprintf('COM_CONTENT_READ_MORE_TITLE'); ?></a>
                <div class="line"></div>
            </div>
        </dd>
    <?php
        $leadingcount++;
    ?>
    </dl>
<?php endforeach; ?>

Answer 2

我唯一能做到的就是这样：

<div class="block-head">
    <h2><?php echo $this->escape($this->params->get('page_heading')); ?></h2>
    <?php foreach ($this->lead_items as &$item) :
              $this->item = &$item;
              echo '<a href="'.JRoute::_(ContentHelperRoute::getCategoryRoute($this->item->catid, $this->item->catid)).'">all news</a>';
           endforeach; ?>
</div><!-- .block-head -->

它必须包含在foreach 语句中，并在它之前包含$this->item = &$item;。
