今天我遇到了一個非常奇怪的錯誤。我受到這樣糟糕的折磨,因爲它打破了我的整個應用程序。當使用PDO時使用MySQL時出現奇怪的錯誤
所以,我已經建立了這個我有一個標準模型的小框架,因此對此進行細分會有點長並且具有描述性。
<?php include('inc/inc.php'); ?>
<?php
if(!empty($_POST['answer']) && !empty($_POST['levelstart'])){
if($stmt = $site->answerQuestion($_POST['levelstart'], $_POST['answer'])){
if($stmt[0]){
echo json_encode(array('success' => true, 'correct' => $stmt[1], 'correctanswer' => $stmt[2], 'round_end' => $stmt[3]));
}else{
echo json_encode(array('success' => false, 'error' => 'error occurred'.$stmt[1]));
}
}else{
echo json_encode(array('sucess' => false, 'error' => 'Unknown error'));
}
}else{
echo json_encode(array('success' => false, 'error' => 'Provide all necessary parameters.'));
}
?>
這段代碼輸出如下內容。
INSERT INTO quiz_level_starts (`user_id`, `question_id`, `time`, `round_id`, `type`, `success`, `ref_id`) VALUES ('4', '10', '1471887809', '', '1', '1', '905'){"success":false,"error":"error occurred23000"}
以上生成的查詢只是一個虛擬的,我簡單地放在一起,所以我不需要簡單測試的參數化。 json數組中的「錯誤」鍵包含錯誤數據,並且錯誤代碼在那裏轉儲。 23000是存在重複唯一列的mysql錯誤代碼,但沒有在查詢中使用的唯一列(請參閱下面的表結構)。
由於函數answerQuestion是一個很長的函數,我只會貼上相關的行。在$ site-> answerQuestion中,它調用一個名爲「insertLevelStarts」的函數,它應該向db中插入一個條目。 這是我如何稱呼它:
if($stmtss = $this->db->insertLevelStarts($_SESSION['user']['id'], $stmts['return'][0]['id'], time(), $roundid, 1, 1, $levelstart)){
,這是它是如何宣稱,相關的和未知的代碼還剩下:
public function insertLevelStarts($user_id, $question_id, $time, $round_id, $type = 0, $success = 0, $refid = 0){
/*
Type=0 start 1 stop
success=0 for start 1 if successfull on stop
*/
$query = 'INSERT INTO quiz_level_starts (`user_id`, `question_id`, `time`, `round_id`, `type`, `success`, `ref_id`) VALUES (:user_id, :question_id, :time, :round_id, :type, :success, :refid)';
echo $this->genFakeQuery($query, array(
':user_id' => $user_id,
':question_id' => $question_id,
':time' => $time,
':type' => $type,
':success' => $success,
':refid' => $refid,
':round_id' => $round_id
));
return $this->execInsert($query, array(
':user_id' => $user_id,
':question_id' => $question_id,
':time' => $time,
':type' => $type,
':success' => $success,
':refid' => $refid,
':round_id' => $round_id
)
);
}
public function genFakeQuery($query, $array){
foreach($array as $key => $val){
$query = str_replace($key, "'$val'", $query);
}
return $query;
}
public function execUpdate($query, $preparray, $updatearr){
try {
$stmt = $this->db->prepare($query);
$stmt->execute(array_merge($preparray, $updatearr));
$rows = $stmt->rowCount();
if($rows > 0){
return array('type' => 'rowsaffected', 'return' => $rows);
}else{
return array('type' => 'noreturn', 'return' => 'none');
}
} catch(PDOException $ex) {
return array('type' => 'error', 'return' => $ex);
}
}
public function updateClause($query, $update, $updatearr){
if(count($update) > 0){
$count = 0;
foreach($update as $k => $v){
if($count > 0){
$query .= ',';
}
$query .= " `$k` = :$k";
$updatearr[":$k"] = $v;
$count++;
}
}
return array('query' => $query, 'updatearr' => $updatearr);
}
上述查詢
INSERT INTO quiz_level_starts (`user_id`, `question_id`, `time`, `round_id`, `type`, `success`, `ref_id`) VALUES ('4', '10', '1471887809', '', '1', '1', '905')
刀片放入如下所示的表格中:
CREATE TABLE IF NOT EXISTS `quiz_level_starts` (
`id` int(11) NOT NULL,
`user_id` int(11) NOT NULL,
`question_id` int(11) NOT NULL,
`time` int(11) NOT NULL,
`type` int(11) NOT NULL,
`success` int(11) NOT NULL,
`ref_id` int(11) NOT NULL,
`round_id` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
ALTER TABLE `quiz_level_starts`
ADD PRIMARY KEY (`id`);
ALTER TABLE `quiz_level_starts`
MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;

好吧,錯誤代碼23000可以有不同的含義http://dev.mysql.com/doc/refman/5.7/en/error-messages-server.html –
您需要從mysql打印更詳細的錯誤信息 –
