Typecho主题非插件置顶功能
添加
在 index.php 的 $this->title(); 前面加上 $this->sticky();例如下面这段代码
<h2 class="title"><a href="<?php $this->permalink() ?>"><?php $this->sticky(); $this->title() ?></a></h2>
//其实就是这个
<?php $this->sticky(); $this->title() ?>创建后台设置选项：
在主题的 functions.php 文件中添加代码，创建一个新的后台设置选项来存储置顶文章的 cid
// 在主题的 functions.php 文件中
$stickyCids = new Typecho_Widget_Helper_Form_Element_Text('stickyCids', NULL, NULL, _t('置顶文章CID'), _t('在这里填入置顶文章CID,支持多填，用英文逗号隔开'));
$form->addInput($stickyCids);
$stickyCids->setAttribute('class', 'j-setting-content j-setting-global');前台index.php添加
<?php
$stickyCids = $this->options->stickyCids;
if ($stickyCids) {
// 用英文逗号分割
$sticky_cids = explode(',', $stickyCids);
// 去除每个元素的空格并过滤掉空元素
$sticky_cids = array_filter(array_map('trim', $sticky_cids), 'trim');
$sticky_html = "<span style='color:red'>[置顶] </span>";
$db = Typecho_Db::get();
$pageSize = $this->options->pageSize;
$select1 = $this->select()->where('type =?', 'post');
$select2 = $this->select()->where('type =? && status =? && created <?', 'post', 'publish', time());
$this->row = [];
$this->stack = [];
$this->length = 0;
$order = '';
$stickyCidMap = [];
$whereClauses = [];
$whereParams = [];
foreach ($sticky_cids as $i => $cid) {
$whereClauses[] = 'cid =?';
$whereParams[] = $cid;
$order.= " when ". $cid. " then ". $i;
$select2->where('table.contents.cid!=?', $cid);
$stickyCidMap[$cid] = $i;
}
if (!empty($whereClauses)) {
$select1->where(implode(' OR ', $whereClauses),...$whereParams);
}
if (empty(trim($order))) {
$orderBy = 'table.contents.created';
$sort = Typecho_Db::SORT_DESC;
} else {
$orderBy = null;
$sort = "(case cid$order end)";
}
if ($orderBy!== null) {
$select1->order($orderBy, $sort);
}
if ($this->_currentPage == 1) {
$stickyPosts = $db->fetchAll($select1);
// 对获取到的置顶文章按照设置的顺序排序
usort($stickyPosts, function ($a, $b) use ($stickyCidMap) {
return $stickyCidMap[$a['cid']] - $stickyCidMap[$b['cid']];
});
foreach ($stickyPosts as $sticky_post) {
$sticky_post['sticky'] = $sticky_html;
$this->push($sticky_post);
}
}
$uid = $this->user->uid;
if ($uid) {
$select2->orWhere('authorId =? && status =?', $uid, 'private');
}
$sticky_posts = $db->fetchAll($select2->order('table.contents.created', Typecho_Db::SORT_DESC)->page($this->_currentPage, $this->parameter->pageSize));
foreach ($sticky_posts as $sticky_post) {
$this->push($sticky_post);
}
$this->setTotal($this->getTotal() - count($sticky_cids));
}
?>
