我有一个PHP类,可以像这样从RSS提要中获取帖子:
1-Post Title 2-post图像 3-post描述 4-post链接到原始
问题是有时后期描述太长了,我需要帮助将描述限制为几个字。
include_once(ABSPATH . WPINC . '/feed.php');
$rss = fetch_feed(' RSS URL ');
if (!is_wp_error( $rss ) ) :
$maxitems = 1;
$rss_items = $rss->get_items(0, $maxitems);
endif;
?>
<?php if ($maxitems == 0) echo 'No items';
else
foreach ( $rss_items as $item ) : ?>
<div id="deals">
<b><a href="<?php echo Clean($item->get_permalink()); ?>" rel="nofollow" target="_blank"><?php echo $item->get_title(); ?></a></b>
<?php echo hapus(Clean($item->get_content())); ?>
<p style="text-align:center;bottom:0;"><a title="Order <?php echo $item->get_title(); ?>" href="<?php echo Clean($item->get_permalink()); ?>" rel="nofollow" target="_blank"><img src="<?php bloginfo('template_url');?>/images/check.jpg" alt="<?php echo $item->get_title(); ?>" /></a></p>
</div>
<div class="clear"></div>
<?php endforeach; ?>
function Clean($result) {
$result = trim($result);
return $result;
}
function hapus($result){
$result = str_replace('<tbody>', '',$result);
$result = str_replace('<tr>', '',$result);
$result = str_replace('<td>', '<p>',$result);
$result = str_replace('</td>', '</p>',$result);
$result = str_replace('</tr>', '',$result);
$result = str_replace('</tbody>', '',$result);
$result = str_replace('<strike>', '',$result);
$result = str_replace('</strike>', '',$result);
$result = str_replace('<table>', '',$result);
$result = str_replace('</table>', '',$result);
$result = str_replace('</p></p>', '</p>',$result);
$result = trim($result);
return $result;
}
