你怎么能在single.php上获得帖子类别

Question

How can you get the post category on single.php?

I've tried:

<h1><?php echo $this->escapeHtml($post->get_the_category()) ?></h1>

&

   <?php echo $this->escapeHtml($post->get_category_parents( $cat, true, ' &raquo; ' )) ?>

&

<h1><?php echo $this->escapeHtml($post->get_the_category($post->ID)) ?></h1>

This is the entire file:

<?php $post = $this->getPost() ?>
<?php if ($post): ?>
    <?php $helper = $this->helper('wordpress') ?>
    <?php $author = $post->getAuthor() ?>


    <div class="page-title post-title">
        <h1><?php echo $this->escapeHtml($post->get_the_category($post->ID)) ?></h1>
        <h1><?php echo $this->escapeHtml($post->getPostTitle()) ?></h1>
    </div>
    <div class="post-view">
        <p class="post-date when"><?php echo stripslashes($this->__('<span class=\"by-author\"> by %s</span> on %s.', $post->getAuthor()->getDisplayName(), $post->getPostDate())) ?></p>
        <?php echo $this->getBeforePostContentHtml() ?>
        <div class="post-entry entry std<?php if ($post->getFeaturedImage()): ?> post-entry-with-image<?php endif; ?>">
            <?php if ($post->isViewableForVisitor()): ?>
<!--                --><?php //if ($featuredImage = $post->getFeaturedImage()): ?>
<!--                    <div class="featured-image left"><img src="--><?php //echo $featuredImage->getAvailableImage() ?><!--" alt="--><?php //echo $this->escapeHtml($post->getPostTitle()) ?><!--"/></div>-->
<!--                --><?php //endif; ?>
                <?php echo $post->getPostContent() ?>
            <?php else: ?>
                <?php echo $this->getPasswordProtectHtml() ?>
            <?php endif; ?>
        </div>
        <?php echo $this->getAfterPostContentHtml() ?>
        <?php echo $this->getCommentsHtml() ?>
    </div>
<?php endif; ?>

I'm working on WordPress through the Fishpig WordPress integration for Magento so the file path is template/wordpress/post/view.phtml.

Tomas is correct; you cannot use WordPress code in a Magento template file, even if that template file is integrating WordPress. None of the WP library code is included so the WP functions that you include do not exist.

It is still possible to get all of the WP data you require via Magento code though. To get a posts categories, use the following code:

<?php $categories = $post->getParentCategories() ?>
<?php if (count($categories) > 0): ?>
    <?php foreach($categories as $category): ?>
        <a href="<?php echo $category->getUrl() ?>"><?php echo $this->escapeHtml($category->getName()) ?></a>
    <?php endforeach; ?>
<?php endif; ?>
