我正在尝试在我使用 jquery 选项卡切换的一个区域中执行不同的提要。我有一个提要模板,每次只需要在其中切换 rss 提要 url。我试图在我的索引页面上为 url 设置一个值,然后在提要中回显它,但我显然没有这样做。我的方法有什么问题?
<----Index Page--->
<div class="news-feed"><?php $url = "http://mysite.com/category/news/feed/"; ?><?php locate_template( array( 'feeds/news-feed.php' ), true ) ?></div>
<-------FEED-------->
<?php // Get RSS Feed(s)
include_once(ABSPATH . WPINC . '/feed.php');
// Get a SimplePie feed object from the specified feed source.
$rss = fetch_feed('$url');<---WHERE I NEED MY CUSTOM URL
if (!is_wp_error( $rss ) ) : // Checks that the object is created correctly
// Figure out how many total items there are, but limit it to 5.
$maxitems = $rss->get_item_quantity(5);
// Build an array of all the items, starting with element 0 (first element).
$rss_items = $rss->get_items(0, $maxitems);
endif;
?>
<ul>
<?php if ($maxitems == 0) echo '<li>No items.</li>';
else
// Loop through each feed item and display each item as a hyperlink.
foreach ( $rss_items as $item ) : ?>
<li>
<a href='<?php echo esc_url( $item->get_permalink() ); ?>'
title='<?php echo esc_html( $item->get_title() ); ?>'>
<?php echo '<img src="' .get_first_image_url($item->get_content()). '"/>'; ?>
<?php echo esc_html( $item->get_title() ); ?></br>
<span style="color:#e2e2e2"><?php echo shorten( $item->get_description (),140 ); ?></span></a>
</li>
<?php endforeach; ?>
</ul>
