Typecho——Argument 1 passed to TypechoRouterget() must be of the type string

前言

开发EasyBe主题的置顶功能时候，测试的时候出现了Typecho\Router::get()报错，根据对应的报错信息查看了下源码后解决了该问题；

内容

查询SQL

// 获取全部文章
function getAllPosts($page, $limit) {
    $db = Typecho_Db::get();
    $sql = $db->select('c.cid', 'c.title', 'c.created', 'c.text', 'c.password', 'c.commentsNum', 'c.views', 'c.digg', 'f.str_value as sticky')
            ->from('table.contents as c')
            ->join('table.fields as f', 'f.cid = c.cid', Typecho_Db::LEFT_JOIN)
            ->where('c.status = ? and c.type = ?', 'publish', 'post')
            ->order('sticky', Typecho_Db::SORT_DESC)
            ->order('c.created', Typecho_Db::SORT_DESC)
            ->page($page, $limit);
    return  $db->fetchAll($sql);
}

报错信息

根据报错，这里我们只需要关注#0的提示即可；

排查经过

根据报错进入到对应的文件中，使用vi进行编辑；

?> 到这里其实问题已经就解决了，因为我上面查询的SQL中，并没有将字段type筛选出来，所以这里才导致了传NULL的情况；

解决

把~c c.type c~加入查询字段即可；

    $db = Typecho_Db::get();
    $sql = $db->select('c.cid', 'c.title', 'c.created', 'c.text', 'c.password', 'c.commentsNum', 'c.views', 'c.type', 'c.digg', 'f.str_value as sticky')
            ->from('table.contents as c')

            ->order('c.created', Typecho_Db::SORT_DESC)

    return  $db->fetchAll($sql);
