1 问题简述

Joe1.4自带「付费可见」→游客支付成功→仍显示灰色遮罩，刷新也不出来。

2 修复思路（30秒看懂）

①支付时把游客IP写进订单表ip字段
②文章渲染时用当前IP查订单status=1
③命中→直接输出隐藏内容，无需登录

3 一键修复代码（复制即用）

3.1 先执行SQL(这里1.4版本不需要)

ALTER TABLE `typecho_orders` ADD `ip` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '游客支付公网IP' AFTER `user_id`;

3.2 全局IP函数（粘贴到function.php顶部）

3.3 替换markdown_hide函数

function markdown_hide($content, $post, $login)
{
    // 如果内容中不存在 {hide} 标签，直接返回原内容
    if (strpos($content, '{hide') === false) return $content;
    // 初始化变量：调用全局的get_visitor_ip()
    $showContent = false;
    $payment = null;
    $visitorIp = get_visitor_ip(); // 直接调用全局函数，无报错
    $currentCid = $post->cid;
    $db = \Typecho\Db::get();
    $prefix = $db->getPrefix();

    // 1. 登录用户：用user_id匹配订单
    if ($login && isset($GLOBALS['JOE_USER']->uid)) {
        $payment = Db::name('orders')->where([
            'user_id' => $GLOBALS['JOE_USER']->uid,
            'status' => 1,
            'content_cid' => $currentCid
        ])->find();
        $showContent = !empty($payment);
    } 
    // 2. 游客：用IP匹配订单（核心修复逻辑）
    else {
        $payment = Db::name('orders')->where([
            'ip' => $visitorIp,
            'status' => 1,
            'content_cid' => $currentCid
        ])->find();
        $showContent = !empty($payment);
    }

    // 原有登录/评论可见逻辑：兼容付费优先，非付费时走原逻辑
    if ($post->fields->hide != 'pay' && !$showContent) {
        if ($post->fields->hide == 'login') {
            $showContent = $login;
        } else {
            $userEmail = $login && isset($GLOBALS['JOE_USER']->mail) ? $GLOBALS['JOE_USER']->mail : $post->remember('mail', true);
            $comment = !empty($userEmail) ? Db::name('comments')->where([
                'cid' => $currentCid,
                'mail' => $userEmail
            ])->find() : null;
            $showContent = !empty($comment);
        }
    }

    // 隐藏内容标签替换：兼容所有{hide*}格式，无多余字符限制
    if ($showContent) {
        $content = preg_replace('/\{hide[^}]*\}/i', '', $content);
        $content = preg_replace('/\{\/hide\}/i', '', $content);
    } else {
        if (strpos($content, '<br>{hide') !== false || strpos($content, '<p>{hide') !== false) {
            $content = preg_replace('/\<br\>\{hide[^}]*\}([\s\S]*?)\{\/hide\}/i', '<br><joe-hide style="display:block"></joe-hide>', $content);
            $content = preg_replace('/\<p\>\{hide[^}]*\}([\s\S]*?)\{\/hide\}/i', '<p><joe-hide style="display:block"></joe-hide>', $content);
        }
        $content = preg_replace('/\{hide[^}]*\}([\s\S]*?){\/hide}/i', '<joe-hide style="display:inline"></joe-hide>', $content);
    }

    // 付费框显示逻辑：非爬虫才显示，区分付费/免费资源
    if ($post->fields->hide == 'pay' && !detectSpider()) {
        if ($post->fields->price > 0) {
            $pay_box_position = $showContent ? _payPurchased($post, $payment) : _payBox($post);
        } else {
            $userEmail = $login && isset($GLOBALS['JOE_USER']->mail) ? $GLOBALS['JOE_USER']->mail : $post->remember('mail', true);
            $comment = !empty($userEmail) ? Db::name('comments')->where([
                'cid' => $currentCid,
                'mail' => $userEmail
            ])->find() : null;
            $pay_box_position = _payFreeResources($post, $comment);
        }
        if (!$post->fields->pay_box_position || $post->fields->pay_box_position == 'top') $content = $pay_box_position . $content;
        if ($post->fields->pay_box_position == 'bottom') $content = $content . $pay_box_position;
    }
    return $content;
