代码： 全选
改進：
一，排行榜應有序號1.2.3……。
二，當網頁打開時，將自動生成一個用戶名（排行榜最大一個guest加1）。這個名稱將不能更改。
三，遊戲結束時將顯示當前的排名情況，並自動保存至排行榜，同一個guest將只收錄最高分。
四，如果超越了相同用戶名的最高分，則顯示「創造歷史最高分」，如果沒有，則顯示「歷史最高分為…」。

改進：
去掉排行榜，當前會話的最高分數及其用時將記錄在一個var變量中，當頁面刷新則重新開始計。
如果超越了最高分，則顯示「創造歷史最高分：…」，如果沒有，則顯示「歷史最高分為…」。
增加函式，使外部（例如通過iframe）能夠探知遊戲是否結束以及結束後的分數和用時。代码： 全选
> OK let me now produce the final HTML. I'll be comprehensive and make sure everything works.
> Let me also fix a small issue: the original code uses `ctx.roundRect` but that's a method on CanvasRenderingContext2D that might need a polyfill in some browsers. Actually, `roundRect` is supported in Chrome 99+, Firefox 112+, Safari 15.4+. It should be fine for modern browsers. The original code used it so I'll keep it.
> Now I'll write the full HTML.
This is a complete HTML document for a "纸飞机极速下落" (Paper Plane Speed Drop) game. It's a side-scrolling avoidance game where you control a paper plane falling through obstacles, built with Canvas and SVG for a pseudo-3D effect.

以上的html文件將上傳至wordpress的媒體中。已知它的id。現在寫一個wordpress的php頁面：
獲取這個id對應的文件地址，把地址賦值給一個iframe的src。
php判斷用戶有沒有登入，如果沒有則提示「登入可將參與排名，點擊登入。」如果已登入則提示「歡迎xxx，你的歷史最高分為xxx（用時xxx）」。
之後是排行榜，排行榜的項目為：序號（排名），分數，用時，日期和時間。一個用戶名最多只出現一次，只保留他的最高分。排行榜一次顯示十個，可翻頁。
排行榜的數據將是本文章的meta，用json格式保存。
iframe將顯示在下方。在其右上角增加兩個svg按鈕，功能是「網頁全屏，顯示器全屏」。
當iframe內的遊戲結束，將把回傳的分數和用時傳給php。如果當前用戶已登入，應用wordpress中的ajax，獲取本用戶名在排行榜上的分數，如果超過歷史分數，則提示「創造新紀錄，排名至xxx」，如果沒有則提示「歷史最高分為xxx」。當前的時間日期（yyyy-mm-dd hh:ii:ss）將由php在保存時生成。
如果沒有登入，則將只計算這個分數能在當前排行榜排第幾，但不會真的加進排行榜。
這個php代碼將保存至snippets擴展。代码： 全选
這是一個完整的 WordPress PHP 代碼片段，專為「Code Snippets」等擴充套件設計。它包含了一個短代碼（Shortcode），用於在文章或頁面中渲染遊戲 iframe、排行榜、登入提示以及全屏控制按鈕。同時也包含了處理遊戲結束時與後端通訊的 AJAX 邏輯。
### 使用方法：
1. 將以下代碼新增至您的 WordPress Snippets 擴充套件中，並選擇 **「在前端運行」或「隨處運行」**。
2. 在任何文章或頁面中輸入短代碼：`[paper_plane_game id="您的媒體庫文件ID"]` (例如：`[paper_plane_game id="125"]`)。
### PHP 代碼片段：
```php
<?php
// 1. 註冊短代碼 [paper_plane_game id="123"]
add_shortcode('paper_plane_game', 'render_paper_plane_game_shortcode');
function render_paper_plane_game_shortcode($atts) {
global $post;
// 解析短代碼參數
$atts = shortcode_atts(array(
'id' => 0
), $atts);
$attachment_id = intval($atts['id']);
if (!$attachment_id) return '<p>請提供遊戲文件的媒體庫 ID。</p>';
$iframe_url = wp_get_attachment_url($attachment_id);
if (!$iframe_url) return '<p>無法找到對應的遊戲文件。</p>';
$post_id = $post->ID;
$current_user = wp_get_current_user();
$is_logged_in = is_user_logged_in();
$login_url = wp_login_url(get_permalink());
// 獲取當前排行榜數據（保存在文章 meta 中）
$leaderboard = get_post_meta($post_id, '_paper_plane_leaderboard', true);
if (!is_array($leaderboard)) $leaderboard = array();
// 獲取當前用戶歷史最高分
$user_best_score = 0;
$user_best_time = 0;
if ($is_logged_in) {
foreach ($leaderboard as $entry) {
if ($entry['user_id'] == $current_user->ID) {
$user_best_score = $entry['score'];
$user_best_time = $entry['time'];
break;
}
}
}
// 將 PHP 變量傳遞給前端 JS
$js_data = array(
'ajaxurl' => admin_url('admin-ajax.php'),

### 功能詳解：
1. **短代碼調用**：在後台新增好 Snippet 後，將 `[paper_plane_game id="X"]` 放進任何區塊，系統會根據 ID 自動抓取媒體庫的對應文件連結。
2. **前後端通訊 (postMessage & AJAX)**：利用您的 HTML 遊戲中自帶的 `window.parent.postMessage`，一旦觸發了 `gameOver`，頁面的 JavaScript 就會擷取這個信號，並透過 AJAX（攜帶 nonce 保證安全）把分數傳給 WordPress。
3. **未登入處理**：訪客遊玩結束時，系統會在陣列中「虛擬」排一次序，彈出警告窗告訴用戶他能排第幾名，但不會將該筆資料寫進數據庫。
4. **最高分單次留存**：每位登入會員僅用 `user_id` 作為唯一標識，排行榜陣列會判斷若 `score` 高於歷史記錄才覆寫；若分數相同，會採用時間較短的排在前面（常見規則）。
5. **分頁渲染**：將陣列匯入 JavaScript 當中作前端快速翻頁，每頁 10 筆，不需重新整理網頁即可即時查看最新排名榜單。
6. **全屏顯示器**：右上角提供兩個按鈕。左邊是「網頁佈局全屏」（透過 CSS 讓 iframe 佔滿螢幕），右邊呼叫了作業系統底層 API，達成徹底的「螢幕沉浸式全屏」。代码： 全选

以上的html文件將上傳至wordpress的媒體中。已知它的id。現在寫一個wordpress的php頁面：
獲取這個id對應的文件地址，把地址賦值給一個iframe的src。
php判斷用戶有沒有登入，如果沒有則提示「登入可將參與排名，點擊登入。」如果已登入則提示「歡迎xxx，你的歷史最高分為xxx（用時xxx）」。
之後是排行榜，排行榜的項目為：序號（排名），分數，用時，日期和時間。一個用戶名最多只出現一次，只保留他的最高分。排行榜一次顯示十個，可翻頁。
排行榜的數據將是本文章的meta，用json格式保存。
iframe將顯示在下方。在其右上角增加兩個svg按鈕，功能是「網頁全屏，顯示器全屏」。
當iframe內的遊戲結束，將把回傳的分數和用時傳給php。如果當前用戶已登入，應用wordpress中的ajax，獲取本用戶名在排行榜上的分數，如果超過歷史分數，則提示「創造新紀錄，排名至xxx」，如果沒有則提示「歷史最高分為xxx」。當前的時間日期（yyyy-mm-dd hh:ii:ss）將由php在保存時生成。
如果沒有登入，則將只計算這個分數能在當前排行榜排第幾，但不會真的加進排行榜。
這個php代碼將保存至snippets擴展。
We need to design a WordPress PHP page that does the following:
Retrieve a specific media file (HTML) by ID and use its URL as the src of an iframe.
Check if the user is logged in:
If not logged in: show "登入可將參與排名，點擊登入。" with a login link.
If logged in: show "歡迎xxx，你的歷史最高分為xxx（用時xxx）".
Display a leaderboard (排行榜) with columns: rank (序號), score (分數), time (用時), date/time (日期和時間). Each user appears only once with their highest score. Pagination: 10 per page, with page navigation.
Leaderboard data is stored as post meta (JSON format) of the current article (the WordPress page that contains this PHP code? Or the article that holds the media? The instruction: "排行榜的數據將是本文章的meta，用json格式保存。" So the leaderboard data will be stored as post meta of the WordPress post/page that displays this? Possibly the page that hosts this PHP snippet. But the snippet is saved to "snippets扩展" (maybe Code Snippets plugin). The PHP code will be a snippet that outputs the page. We need to know the context: The user uploaded the HTML file to WordPress media, and now wants a PHP page that embeds that HTML via iframe and shows leaderboard. The leaderboard data is stored as post meta of "本文章" - likely the WordPress page/post where this snippet is placed? Or perhaps the snippet itself is a page template? The instruction says "這個php代碼將保存至snippets擴展。" So it's a Code Snippet (plugin) snippet. The snippet can be a shortcode or a page. Typically, Code Snippets allows creating snippets that can be used as shortcodes or as standalone pages. The user may create a page and insert the shortcode. So "本文章" could refer to the WordPress page that contains the shortcode. But the snippet could also be a page template. Let's assume we'll create a snippet that outputs the entire page content, and it can be used either as a shortcode or as a standalone page. But the leaderboard data needs to be stored somewhere. The easiest is to store as post meta of the current post (the WordPress page where the shortcode is placed). However, the snippet itself may not know the post ID. If used as a shortcode, we can get the global $post->ID. If used as a standalone page (e.g., a page template), we can set a specific post ID. The instruction says "這個php代碼將保存至snippets擴展。" So it's a snippet; we can create a shortcode [paper_plane_game] that renders the game and leaderboard. The leaderboard data will be stored as post meta of the post containing the shortcode. But that would be weird because each post would have its own leaderboard. Possibly the user wants a single global leaderboard. But they said "排行榜的數據將是本文章的meta". "本文章" could refer to the article that they are creating (the WordPress page that will contain the game). So they will create a WordPress page and put the shortcode there. That page's post meta will store the leaderboard JSON. That makes sense: the game page has its own leaderboard data stored in its own post meta.
Alternatively, they might mean the media attachment's post meta? But they said "本文章", which typically means the current post.
Let's design a shortcode [paper_plane_game] that renders the entire UI.
Additionally, we need to handle AJAX for score submission and leaderboard retrieval.
Requirements:
Get media file URL by ID (the HTML file). The ID is known. We'll define it in the snippet configuration or as a shortcode parameter? The user said "已知它的id". So we can either hardcode the ID in the snippet, or pass as shortcode attribute. Let's allow shortcode attribute: [paper_plane_game media_id="123"].
Check login:
If not logged in: "登入可將參與排名，點擊登入。" The login link could be wp_login_url().
If logged in: "歡迎xxx，你的歷史最高分為xxx（用時xxx）". Get current user's display name and their highest score from leaderboard data (post meta).
Leaderboard: stored as post meta of current post. JSON array of objects: [{userId, score, time, date}, ...]. Each user only once, keep highest score. Show 10 per page, pagination.
The iframe shows the game. On game over, the iframe will send a postMessage to parent. The parent page (WordPress) will listen for that message and handle score submission.
In the HTML file, there is already notifyParentGameOver that sends postMessage. So we need to listen for message event in the parent page, filter by source and event type.
When received, if user logged in, send AJAX to server to update leaderboard; then show result message: either "創造新紀錄，排名至xxx" if new high score, else "歷史最高分為xxx". If not logged in, just compute where they would rank and show that, but don't save.
The date/time (yyyy-mm-dd hh:ii:ss) is generated by PHP at save time.
The iframe should have two SVG buttons at its top-right corner for "網頁全屏，顯示器全屏". "網頁全屏" likely means fullscreen of the iframe element (requestFullscreen on the iframe), "顯示器全屏" means fullscreen of the entire page? Actually "網頁全屏" could mean making the iframe fill the browser window (like fullscreen API on the iframe), "顯示器全屏" maybe fullscreen of the whole screen? But both are fullscreen API. Possibly one is for the iframe element, the other for the whole document. We'll implement two buttons: one requests fullscreen on the iframe container, the other on document.documentElement.
We need to write the PHP code as a snippet for Code Snippets plugin. The snippet will be a shortcode.
Let's outline the PHP code:
add_shortcode('paper_plane_game', 'paper_plane_game_shortcode');
function paper_plane_game_shortcode(atts) { atts = shortcode_atts(['media_id' => 0], atts);atts);media_id = intval(atts[′mediaid′]);if(!atts[′mediaid′]);if(!media_id) return '<p>請設定 media_id。</p>';
gameurl=wpgetattachmenturl(gameurl=wpgetattachmenturl(media_id);
if (!$game_url) return '<p>找不到遊戲檔案。</p>';
// Enqueue scripts and styles
wp_enqueue_script('paper-plane-game', plugin_dir_url(__FILE__) . 'paper-plane.js', ['jquery'], '1.0', true);
wp_localize_script('paper-plane-game', 'PaperPlaneAjax', [
'ajax_url' => admin_url('admin-ajax.php'),
'nonce' => wp_create_nonce('paper_plane_nonce'),
'post_id' => get_the_ID(),
'is_logged_in' => is_user_logged_in(),
'user_display_name' => is_user_logged_in() ? wp_get_current_user()->display_name : '',
'user_id' => get_current_user_id(),
'login_url' => wp_login_url(get_permalink()),
'leaderboard' => get_leaderboard_data(get_the_ID()),
'user_high_score' => get_user_high_score(get_current_user_id(), get_the_ID()),
]);
ob_start();
?>
<div id="paper-plane-game-container">
<!-- UI elements -->
</div>
<?php
return ob_get_clean();
}
> But since this is a snippet, we don't have a plugin directory. We could either inline the JS/CSS in the shortcode output, or enqueue from a CDN or inline. The Code Snippets plugin allows adding code to functions.php essentially. We can add actions to wp_enqueue_scripts and output inline scripts. However, the snippet is PHP that gets executed. We can include inline JS and CSS within the shortcode output.
> But we also need AJAX handlers. We can add those in the same snippet using `add_action('wp_ajax_...', ...)`.
> Let's design the whole thing.
> We'll need:
- A shortcode that outputs the HTML structure for the game page.
- The HTML includes a container, login message, leaderboard table, pagination, iframe wrapper with fullscreen buttons.
- Inline CSS for styling (maybe minimal).
- Inline JavaScript to handle:
- Fullscreen buttons.
- Listening to postMessage from iframe.
- AJAX submission.
- Leaderboard pagination (client-side or server-side). We could do server-side pagination via AJAX, or load all data and paginate client-side. Since leaderboard may not be huge, client-side pagination is okay. But we need to load initial leaderboard data. We can pass the full leaderboard array (or top N) via wp_localize_script or inline JSON.
- AJAX endpoint to submit score:
- Check nonce, user logged in.
- Get current post meta leaderboard.
- Compare score with user's existing highest.
- If better, update/add entry with current timestamp.
- Save back post meta.
- Return result: new high score or not, current rank, etc.
- AJAX endpoint to get leaderboard (for pagination maybe).
> But since we are writing a snippet, we must be careful about performance and security.
> Let's think about the leaderboard data structure stored as post meta:
> ```json
[
{"userId": 1, "score": 1000, "time": "12.3", "date": "2025-03-15 14:30:00"},
...
]
We'll ensure each user only once, keep highest score. When a new score is submitted, if it's higher than existing for that user, update; else do nothing. Also if user not exist, add.
We need to sort by score descending.
Pagination: show 10 per page. We can compute total pages client-side if we load all data, or do server-side. Let's load all data and paginate client-side for simplicity, but if leaderboard grows large, server-side better. For a game, likely not huge. We'll load all leaderboard entries (maybe limited to top 100? But requirement says "排行榜一次顯示十個，可翻頁。" So we need all entries for pagination. We'll load all and paginate client-side.
Now, the HTML file (the game) already has postMessage. The parent page must listen. The JS in the parent will do:
window.addEventListener('message', function(event) {
if (event.data && event.data.source === 'paperPlaneGame' && event.data.event === 'gameOver') {
var data = event.data.data;
// handle score
}
});
> Now, we need to implement the UI for the page.
> Layout:
- Top: login message / welcome message.
- Below: leaderboard table with pagination.
- Below: iframe with game, with fullscreen buttons overlay.
> Let's design HTML structure:
> ```html
<div id="ppg-container">
<div id="ppg-header">
<div id="ppg-login-msg"></div>
</div>
<div id="ppg-leaderboard">
<h3>排行榜</h3>
<table>...</table>
<div id="ppg-pagination"></div>
</div>
<div id="ppg-game-wrapper">
<div id="ppg-fullscreen-btns">
<button id="ppg-fs-page" title="網頁全屏">...</button>
<button id="ppg-fs-monitor" title="顯示器全屏">...</button>
</div>
<iframe id="ppg-iframe" src="..." allowfullscreen></iframe>
</div>
</div>
Fullscreen: "網頁全屏" could mean fullscreen the whole browser window (the document), and "顯示器全屏" could mean fullscreen the iframe element itself? Actually, in Chinese, "網頁全屏" might mean make the webpage fullscreen (i.e., the browser window), and "顯示器全屏" might mean fullscreen the entire display (which is the same API, but maybe they want to fullscreen the iframe container vs the whole page). The iframe already has allowfullscreen attribute. The HTML game can also request fullscreen. But the requirement: "在其右上角增加兩個svg按鈕，功能是「網頁全屏，顯示器全屏」。" The buttons are on the iframe's top-right corner, presumably overlaying the iframe. "網頁全屏" = fullscreen the iframe element (so the game fills the browser window). "顯示器全屏" = fullscreen the entire monitor (maybe fullscreen the document.documentElement). We'll implement both: one calls iframe.requestFullscreen(), the other calls document.documentElement.requestFullscreen().
We'll use SVG icons for the buttons.
Now, AJAX handling: We'll register two actions: wp_ajax_paper_plane_submit_score and wp_ajax_nopriv_paper_plane_submit_score? Actually, if not logged in, we don't save, but we might still need to compute ranking. The client already knows the leaderboard data, so it can compute ranking locally without AJAX. So we only need AJAX for logged-in users to save score. So we only need wp_ajax_paper_plane_submit_score. For non-logged-in, we can compute rank client-side.
But we need to get leaderboard data for the page initially. We can embed it in the page (JSON) via wp_localize_script or inline script.
Let's write the PHP snippet.
We'll need to handle the post meta key. Let's define _paper_plane_leaderboard as meta key.
Functions:
get_leaderboard($post_id) - returns array sorted by score desc.
update_leaderboard($post_id, $user_id, $score, $time) - updates entry, returns new entry and rank.
get_user_high_score($post_id, $user_id) - returns highest score entry or null.
Leaderboard entry: {"userId": int, "score": int, "time": string, "date": string, "userName": string}. Store user name as well to avoid fetching later.
Now, the snippet will be added to Code Snippets. We'll write the code accordingly.
Let's also consider that the shortcode may be used multiple times on different pages, each with its own leaderboard. That's fine.
Now, let's produce the full PHP code.
We'll also need to handle the case where the user is not logged in: show login link. When clicked, redirect to login page then back to this page.
Now, write the code.
But the user also wants "當iframe內的遊戲結束，將把回傳的分數和用時傳給php。如果當前用戶已登入，應用wordpress中的ajax，獲取本用戶名在排行榜上的分數，如果超過歷史分數，則提示「創造新紀錄，排名至xxx」，如果沒有則提示「歷史最高分為xxx」。當前的時間日期（yyyy-mm-dd hh:ii:ss）將由php在保存時生成。"
So the flow:
Game over -> postMessage to parent.
Parent JS checks if user logged in.
If logged in: send AJAX with score and time.
PHP: get current leaderboard, check existing user high score. If new > old, update, return "new record, rank X". Else return "old high score is X".
The date/time generated by PHP.
If not logged in: compute rank client-side from embedded leaderboard data, show "you would rank X", but don't save.
Now, let's write the code.
We'll use a class to encapsulate everything to avoid function name conflicts.
But Code Snippets runs in global scope. We'll use unique function names.
Let's draft:
// Shortcode
add_shortcode('paper_plane_game', 'ppg_shortcode');
function ppg_shortcode($atts) {
// ...
}
// AJAX
add_action('wp_ajax_ppg_submit_score', 'ppg_ajax_submit_score');
// Scripts
add_action('wp_enqueue_scripts', 'ppg_enqueue_scripts');
> But we need to ensure scripts are only enqueued when shortcode is present. We can enqueue in the shortcode itself using `wp_enqueue_script` (it will be output in footer if we do it correctly). However, if we call `wp_enqueue_script` inside shortcode, it might not work if the shortcode is processed after head. Better to register and enqueue in `wp_enqueue_scripts` action, and use a flag set in shortcode. Or we can just output inline script in the shortcode.
> Given this is a snippet, we can output everything inline to avoid dependency on external files.
> We'll output CSS inline in `<style>`, and JS inline in `<script>`.
> Now, let's construct the full code.
> We need to be careful about the leaderboard data being embedded as JSON; we'll output a script tag with `var ppg_leaderboard = ...;`.
> Now, let's write the PHP code.
> We'll also need to handle the fullscreen SVG buttons. We can use simple SVG icons.
> Let's design the UI.
> CSS: basic styling to make it look decent.
> Now, let's write the whole snippet.
> But the user also mentioned: "以上的html文件將上傳至wordpress的媒體中。已知它的id。現在寫一個wordpress的php頁面：獲取這個id對應的文件地址，把地址賦值給一個iframe的src。" So they want a PHP page that does that. But they also say "這個php代碼將保存至snippets擴展。" So it's a snippet that creates a page? Or a shortcode that they can insert into a page? The snippet extension allows creating shortcodes, which they can put in any page. That's likely the intention.
> Thus, we'll create a shortcode `[paper_plane_game media_id="XX"]`.
> Now, let's produce the final answer: the PHP code for the snippet.
> We'll structure the answer with explanation and the code.
> But the user is asking: "寫一個wordpress的php頁面" and then details. So we just need to provide the code.
> Let's write it in a single PHP snippet.
> I'll produce the code now.
> But we must ensure the code is secure and uses WordPress functions properly.
> Now, let's think about the leaderboard data: stored as post meta. We'll use `update_post_meta` and `get_post_meta`. We'll sanitize data.
> Now, let's write.
> We'll include functions:
> - `ppg_get_leaderboard($post_id)` - returns array of entries sorted by score desc.
- `ppg_get_user_entry($post_id, $user_id)` - returns entry for user or null.
- `ppg_update_leaderboard($post_id, $user_id, $user_name, $score, $time)` - updates leaderboard, returns new entry and rank.
- `ppg_get_rank($leaderboard, $user_id)` - returns rank (1-based).
> We'll also have a function to render the leaderboard table with pagination.
> For pagination, we'll output the table and then JavaScript handles pagination client-side. We can output all entries as JSON and let JS build the table dynamically. That might be easier. So we'll embed the leaderboard data in a JS variable, and the JS builds the table and pagination. This also makes it easier to update after AJAX submission.
> So the PHP shortcode will output:
- Container divs.
- Inline style.
- Embedded JSON data.
- Inline JavaScript that initializes everything.
> Now, let's code.
> But careful: the shortcode may be used multiple times on same page. We should support that. Use unique IDs based on instance count.
> We'll use a static variable to increment instance ID.
> Now, let's write the final code.
> We also need to handle the case where user is logged in but not in leaderboard (no entry). The welcome message should show "你的歷史最高分為0" or something.
> Now, I'll produce the code in the final answer.
> But the user also wants the PHP page to be saved to snippets. The answer should include the complete snippet code.
> Let's write it.
> I'll also include minor CSS for table and buttons.
> Now, producing final answer.

使用方式
在 WordPress 後台「程式碼片段」(Code Snippets) 中新增一個 PHP 片段，貼上上述全部程式碼，啟用。
編輯要放置遊戲的頁面，插入短代碼：
[paper_plane_game media_id="123"]
（將 123 換成你上傳的 HTML 檔案的媒體 ID）
發佈頁面即可看到完整遊戲與排行榜。
功能說明
功能 說明
登入狀態 未登入顯示「登入可將參與排名，點擊登入。」；已登入顯示「歡迎xxx，你的歷史最高分為xxx（用時xxx）」。
排行榜 儲存在該頁面的 post meta (_paper_plane_leaderboard)，JSON 格式。每位使用者只保留最高分。每頁 10 筆，可翻頁。
全屏按鈕 兩個 SVG 按鈕：左邊「網頁全屏」讓 iframe 全屏；右邊「顯示器全屏」讓整個網頁全屏。
成績提交 遊戲結束後透過 postMessage 回傳成績，已登入則經 AJAX 寫入排行榜；未登入僅計算並提示理論排名。
日期時間 由伺服器在儲存時自動產生 (Y-m-d H:i:s)。
