我碰到了一些與我的項目有關的問題。像許多書呆子一樣，我決定創建自己的視頻遊戲評論網站。評論存儲在數據庫中，並且可以通過遊戲的標題檢索通過URL：處理'。'通過url傳遞給MySQL查詢的字符
http://www.example.com/reviews/ {gameName}/{可選 pageOfReview}
不幸的是，測試的邊緣情況時，我來到發生奇怪的錯誤 - 如果遊戲在標題中有一段時間，我無法檢索它。如果這段時間是標題的主角（如.hack），我會得到一個Kohana堆棧跟蹤錯誤屏幕，告訴我評論（或者更確切地說，遊戲）不存在。如果它位於標題的中間或末尾，我會收到一條自己的錯誤消息，說明無法檢索評論（遊戲）。有沒有辦法解決？這是MySQL解析一段時間或其他問題的問題嗎？
編輯：所有查詢都通過Kohana 2的ORM功能使用MySQLi驅動程序進行處理。節能審查（管理控制器）：
public function saveReview()
{
$this->checkAdmin();
if (isset($_POST['submit'])) { $this->storeReview(); }
else { header('Location: /admin'); }
}
private function storeReview($id = null)
{
if (!preg_match("/^[a-zA-Z0-9\-_:!'. ]*$/", $_POST['gameTitle']) || empty($_POST['gameTitle'])) { $gameTitle = false; }
else { $gameTitle = ucwords($this->clean($_POST['gameTitle'])); }
if (!is_numeric($_POST['genre'])) { $genre = false; }
else { $genre = $_POST['genre']; }
$platformCheckArray = array_map('is_numeric', $_POST['platforms']);
$platformCheck = true;
foreach ($platformCheckArray as $pca)
{
if (!$pca)
{
$platformCheck = false;
break;
}
}
$proCheck = true;
$cleanedPros = array();
foreach ($_POST['pros'] as $pro)
{
if (!preg_match("/^[a-zA-Z0-9\-_:!' ]*$/", $pro))
{
$proCheck = false;
break;
}
if (!empty($pro)) { $cleanedPros[] = $this->clean($pro); }
}
$conCheck = true;
$cleanedCons = array();
foreach ($_POST['cons'] as $con)
{
if (!preg_match("/^[a-zA-Z0-9\-_:!' ]*$/", $con))
{
$conCheck = false;
break;
}
if (!empty($con)) { $cleanedCons[] = $this->clean($con); }
}
if (!is_numeric($_POST['score'])) { $score = false; }
else { $score = $_POST['score']; }
if (empty($_POST['content'])) { $content = false; }
else { $content = true; }
// save review if all tests pass, display error otherwise
if ($gameTitle && $genre && $platformCheck && $proCheck && $conCheck && $score && $content)
{
$gameTitle = $gameTitle;
$platforms = $_POST['platforms'];
$reviewContent = $_POST['content'];
$prosText = implode(', ', $cleanedPros);
$consText = implode(', ', $cleanedCons);
$game = ORM::factory('game');
$game->title = $gameTitle;
$game->genre_id = $genre;
$game->platforms = $platforms;
$game->save();
$storedGenre = ORM::factory('genre')->where('id', $genre)->find();
$storedGenre->platforms = $platforms;
$storedGenre->save();
$review = ORM::factory('review', $id);
$review->content = $reviewContent;
$review->score = $score;
$review->game_id = $game->id;
$review->date_added = date('Y-m-d H:i:s');
$review->platforms = $platforms;
$review->save();
$pros = ORM::factory('pro');
$pros->review_id = $review->id;
$pros->text = $prosText;
$pros->save();
$cons = ORM::factory('con');
$cons->review_id = $review->id;
$cons->text = $consText;
$cons->save();
if ($game->saved && $storedGenre->saved && $review->saved && $pros->saved && $cons->saved) { $this->success('review'); }
else { $this->showError("Something went wrong with saving the review. Please try again."); }
}
else { $this->showError("All fields must contain values. Please try again."); }
}
檢索複審（從評論控制器）：
public function show($id, $page = 1)
{
if (is_numeric($id)) { $game = ORM::factory('game', $id); }
else
{
$id = ucwords(stripslashes($id));
$game = ORM::factory('game')->where('title', $id)->find();
}
if ($game->loaded) { $this->showReview($game->id, $page); }
else { HandiError::factory('Could not retrieve the specified review. Please check that you entered the correct value.'); }
}
private function showReview($id, $page = 1)
{
$page = (int)$page;
if ($page < 1) { $page = 1; }
if ($id)
{
$game = ORM::factory('game', $id);
$review = ORM::factory('review')->where('game_id', $game->id)->find();
$genre = ORM::factory('genre')->where('id', $game->genre_id)->find();
$revPlatforms = $this->db->query("SELECT * FROM platforms
INNER JOIN platforms_reviews AS pr ON platforms.id = pr.platform_id
INNER JOIN reviews ON pr.review_id = reviews.id
WHERE reviews.id = ?", $review->id);
$revPros = ORM::factory('pro')->where('review_id', $review->id)->find();
$revCons = ORM::factory('con')->where('review_id', $review->id)->find();
$platforms = array();
foreach($revPlatforms as $rp) { $platforms[] = $rp->name; }
$pros = explode(', ', $revPros->text);
$cons = explode(', ', $revCons->text);
$pages = explode('<split />', $review->content);
$count = count($pages);
if ($page > ($count)) { $content = $pages[0]; }
else { $content = $pages[$page - 1]; }
$view = new View('reviews/show_review');
$view->content = $content;
$view->gameTitle = $game->title;
$view->genre = $genre->name;
$view->platforms = implode(', ', $platforms);
$view->pros = $pros;
$view->cons = $cons;
$view->score = $review->score;
$view->pages = $pages;
$view->render(true);
}
else { HandiError::factory('Could not retrieve the specified review. Please check that you entered the correct value.'); }
}
編輯2：嗯，我發現了一些關於超前時段情況：
在我的管理員索引中，我有幾個查詢用於根據遊戲標題，平臺，流派等列出評論。它基本上是一個窮人的維基。請參閱：
public function index()
{
/* show a wiki-like page with reviews listed by title,
* game title, genre, and platform
*/
$numGenres = $this->db->query("SELECT COUNT(id) AS num FROM genres");
$numPlatforms = $this->db->query("SELECT COUNT(id) AS num FROM platforms");
$genreCount = $numGenres[0]->num;
$platformCount = $numPlatforms[0]->num;
$scoreCount = 5;
$genreResults = array();
$platformResults = array();
$scoreResults = array();
$gameResults = $this->db->query("SELECT LEFT(title, 1) AS letter, COUNT(id) AS count FROM games GROUP BY letter ORDER BY letter ASC");
for($i = 1; $i < ($genreCount + 1); ++$i)
{
$genreResults[] = $this->db->query("SELECT genres.id AS id, genres.name AS name, COUNT(reviews.id) AS num FROM reviews
INNER JOIN games ON reviews.game_id = games.id
INNER JOIN genres ON games.genre_id = genres.id
WHERE genres.id = ?", $i);
}
for($j = 1; $j < ($platformCount + 1); ++$j)
{
$platformResults[] = $this->db->query("SELECT platforms.id AS id, platforms.name AS name, COUNT(reviews.id) AS num FROM reviews
INNER JOIN platforms_reviews AS pr ON reviews.id = pr.review_id
INNER JOIN platforms ON pr.platform_id = platforms.id
WHERE platforms.id = ?", $j);
}
for($k = 1; $k < ($scoreCount + 1); ++$k)
{
$scoreResults[] = $this->db->query("SELECT score, COUNT(id) AS num FROM reviews WHERE score = ?", $k);
}
$view = new View('reviews/index');
$view->gamesByLetter = $gameResults;
$view->genres = $genreResults;
$view->platforms = $platformResults;
$view->scores = $scoreResults;
$view->render(true);
}
當我將這些查詢的結果傳遞給視圖時，我循環遍歷它們並創建基於元類別的鏈接。因此，它顯示了多少遊戲以字母A，B等開始，並且點擊其中一個鏈接將用戶帶到鏈接列表，每個鏈接都帶有評論（所以，A-> Afterburner（等等））， - >對Afterburner的評論）。
當我將鼠標懸停在具有領先期的組上時，我的狀態欄顯示鏈接中缺少該時間段，即使它顯示在源中。所以，即使源代碼顯示鏈接爲site.com/reviews/game/。瀏覽器將其顯示爲site.com/reviews/game/這讓我相信這段時間甚至沒有被傳遞到方法中，堆棧跟蹤似乎證實（它聲稱有一個缺失的參數，這將是期間）。
編輯3：好吧，我看看我的路線，並找不到任何東西。這就是說，我確實有一個.htaccess文件，mod_rewrite的路線看起來漂亮的SEO，所以我想知道如果這可能是問題。我自己從來沒有寫過mod_rewrite文件 - Kohana論壇上的人給了我這個，它工作，所以我去了。我可以理解一些涉及的regEx，但是我的regEx Fu很弱。我相信最後一行是'魔術'。
# Turn on URL rewriting

如果我正在閱讀這個權利，那麼'。'只是指任何單個字符。
Can a'。'除了表示文件擴展名或網址後綴（.com，.org等）之外，還可以在格式正確的URL中使用？我的意思是，當我將鼠標懸停在他們的鏈接上時，它們並未出現在Firefox的狀態欄中，這導致我認爲這是瀏覽器/格式良好問題，而不是編碼問題。
你能張貼您用來檢索查詢評價？ PHP代碼將會很有幫助，如果可能的話，它會在發送給MySQL之前將最終語句的回顯/打印輸出。 – Mike 2010-07-27 20:54:08
我不使用Kohana - 是否（或可以）堆棧跟蹤包括導致問題的SQL查詢？ – Mike 2010-07-27 21:08:31
從我能看到的，沒有。 – 2010-07-27 21:14:04
