似乎我的第二個MySQL查詢失敗,原因不明。只有當從$ dbLink-> query()獲得結果時,連接時纔會出現問題。PHP MySQL第二次查詢失敗
$photos = getPhotos(getID($_COOKIE[$uname_cookie], $_COOKIE[$passwd_cookie]));
function getID($uName, $passwd) {
// Just in case, for modularity :P
include 'misc.php';
$query = "SELECT ID FROM Users WHERE UserName = '" . $uName . "' AND Password = '" . $passwd . "';";
$dbLink = new mysqli($host, $user, $pass, $dbname);
if ($dbLink->connect_errno) {
echo "Failed to connect to database: " . $dbLink->connect_error;
return null;
} else {
$results = $dbLink->query($query);
print_r($results->fetch_array());
$rows = $results->fetch_array();
return $rows["ID"];
}
}
function getPhotos($id) {
// Just in case, for modularity :P
include 'misc.php';
$query = "SELECT Location FROM Photos WHERE UserID = " . $id . ";";
$dbLink = new mysqli($host, $user, $pass, $dbname);
if ($dbLink->connect_errno) {
echo "Failed to connect to database: " . $dbLink->connect_error;
return null;
} else {
$results = $dbLink->query($query);
print_r($results->fetch_array());
$rows = $results->fetch_array();
return $rows["ID"];
}
}
編輯:明白了周圍的$ DBLINK傳遞給函數IE getPhotos($ ID,$ DBLINK)
你迫切需要在[適當的SQL轉義(HTTP讀了起來: 'mysqli'。您應該使用'bind_param',而不是將原始用戶數據插入到查詢字符串中。 – tadman 2013-04-10 21:10:30
沒有錯誤或任何?另外,你可能想分開實例化數據庫,以避免有許多不同但平等的連接。 – Think 2013-04-10 21:11:15
@tadman我不斷點擊向上箭頭,但它只能讓我給你一個upvote! (jk) – 2013-04-10 21:11:31
