php – MySQL事务 – 更新2个表

我有一个表单,要求用户验证他们的电子邮件地址,该链接将发送给用户

http://app.myurl.org/h/activate.PHP?email=useremail@gmail.com\u0026amp;key=80fddb7fa21dd2e2639ae5ec82b9d511\u0026amp;api=8a2d01d7411ec2488307744ddf070a4d

用户被定向到activate.PHP

我试图从网址获取电子邮件,密钥和API.

然后我尝试更新用户表和名册表.

要更新的wrightway_roster表列是激活

wrightway_users要更新的表列是组

它们都传递MD5随机散列的唯一值.一切都很顺利,而不是TRANSACTION查询.

<?PHP
include ('database_connection.PHP');
if (isset($_GET['email']) && preg_match('/^([a-zA-Z0-9])+([a-zA-Z0-9\._-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/', $_GET['email'])) { $email = $_GET['email']; }
if (isset($_GET['key']) && (strlen($_GET['key']) == 32)) { $key = $_GET['key'];}
if (isset($_GET['api']) && (strlen($_GET['api']) == 32)) { $API = $_GET['api'];}
if (isset($email) && isset($key)) {
    MysqLi_query($dbc, "START TRANSACTION");
    $result_activate_account = MysqLi_multi_query($dbc,"
       UPDATE table_users SET groups=[99] WHERE(pinAPP_API ='$API') LIMIT 1;
       UPDATE wrightway_roster SET Activation=NULL WHERE(email ='$email' AND Activation='$key')LIMIT 1;
    ");
    if ($result_activate_account !== false) {
        MysqLi_query($dbc, "COMMIT");
        echo '<div>You may Now proceed.</div>';
    } else {
        MysqLi_query($dbc, "ROLLBACK");
        echo '<div>Oops !You Could not be validated. Please recheck the link or contact your hiring manager.</div>';
    }
    MysqLi_close($dbc);
} else {
    echo '<div>An Error Occurred.</div>';
}
?>

PHP是5.4 Native

激活和组都是VARCHAR

这些查询起作用,并且完全符合预期.

“UPDATE wrightway_users SET groups ='[99]’WHERE(pinAPP_API =’$API’)LIMIT 1;”;

UPDATE wrightway_roster SET Activation = NULL WHERE(email =’$email’AND Activation =’$key’)LIMIT 1“;

我正在使用单个查询或者我需要它做什么,我写了上面的内容来使用Transactions.

if (isset($email) && isset($key)) {

     // Update the database to set the "activation" field to null

     $query_activate_account = "UPDATE wrightway_users SET groups='[99]' WHERE(pinAPP_API ='$API') LIMIT 1;";

     $result_activate_account = MysqLi_query($dbc, $query_activate_account);

     // Print a customized message:
     if (MysqLi_affected_rows($dbc) == 1) //if update query was successful
     {
     echo '<div>You may Now proceed.</div>';

     } else {
     echo '<div>Oops !You Could not be validated. Please recheck the link or contact your hiring manager.</div>';

     }

     MysqLi_close($dbc);

    } else {
     echo '<div>An Error Occurred.</div>';
    }

解决方法:

MysqL不接受这种语法

UPDATE wrightway_users SET groups=[99] ...
                                  ^  ^

也许其中一个会更好：

UPDATE wrightway_users SET groups=99 ...
UPDATE wrightway_users SET groups="99"
UPDATE wrightway_users SET groups="[99]"

根据您的需要和团体类型.

阅读this answer似乎证实了这一点.
