上一篇文章$this->thePrev()
下一篇文章$this->theNext()
输出中包含有a标签,应该如何获取单纯的链接地址 和 文章标题?
是需要修改系统核心还是可以有更简单的方法?
系统核心代码:
public function theNext($format = '%s', $default = NULL, $custom = array())
{
$content = $this->db->fetchRow($this->select()->where('table.contents.created > ? AND table.contents.created < ?',
$this->created, $this->options->gmtTime)
->where('table.contents.status = ?', 'publish')
->where('table.contents.type = ?', $this->type)
->where('table.contents.password IS NULL')
->order('table.contents.created', Typecho_Db::SORT_ASC)
->limit(1));
if ($content) {
$content = $this->filter($content);
$default = array(
'title' => NULL,
'tagClass' => NULL
);
$custom = array_merge($default, $custom);
extract($custom);
$linkText = empty($title) ? $content['title'] : $title;
$linkClass = empty($tagClass) ? '' : 'class="' . $tagClass . '" ';
$link = '<a ' . $linkClass . 'href="' . $content['permalink'] . '" title="' . $content['title'] . '">' . $linkText . '</a>';
printf($format, $link);
} else {
echo $default;
}
}
public function thePrev($format = '%s', $default = NULL, $custom = array())
{
$content = $this->db->fetchRow($this->select()->where('table.contents.created < ?', $this->created)
->where('table.contents.status = ?', 'publish')
->where('table.contents.type = ?', $this->type)
->where('table.contents.password IS NULL')
->order('table.contents.created', Typecho_Db::SORT_DESC)
->limit(1));
if ($content) {
$content = $this->filter($content);
$default = array(
'title' => NULL,
'tagClass' => NULL
);
$custom = array_merge($default, $custom);
extract($custom);
$linkText = empty($title) ? $content['title'] : $title;
$linkClass = empty($tagClass) ? '' : 'class="' . $tagClass . '" ';
$link = '<a ' . $linkClass . 'href="' . $content['permalink'] . '" title="' . $content['title'] . '">' . $linkText . '</a>';
printf($format, $link);
} else {
echo $default;
}
}
