Question

我在下面的代码中遇到了一个问题，当我尝试更新这些字段时，由于喜欢，学校，校园字段，我的查询不起作用＆amp; else部分执行，但当我从查询中删除这3它工作正常。请帮助我，thx提前和PHP＆amp; html代码如下： -

php： -

if(isset($_POST['nametb']) && isset($_POST['usernametb']) && isset($_POST['emailtb']) && isset($_POST['confirmtb']) && isset($_POST['abouttb']) && isset($_POST['interesttb']) && isset($_POST['dreamtb']) && isset($_POST['liketb']) && isset($_POST['schooltb']) && isset($_POST['schoolyrtb']) && isset($_POST['occupationtb']) && isset($_POST['occupationyrtb']) && isset($_POST['passwordstb']))
            {

                $nametb = $_POST['nametb'];
                $usernametb = $_POST['usernametb'];
                $emailtb = $_POST['emailtb'];
                $confirmtb = $_POST['confirmtb'];
                $abouttb = $_POST['abouttb'];
                $interesttb = $_POST['interesttb'];
                $dreamtb = $_POST['dreamtb'];
                $liketb = $_POST['liketb'];
                $schooltb = $_POST['schooltb'];
                $schoolyrtb = $_POST['schoolyrtb'];
                $occupationtb = $_POST['occupationtb'];
                $occupationyrtb = $_POST['occupationyrtb'];
                $passwordtb = $_POST['passwordstb'];
                $passwordstb = md5($passwordtb);            

                if(!empty($nametb) && !empty($usernametb)){

                    if(!empty($passwordtb)){

                        $password_get = "SELECT id from user_login WHERE password='$passwordstb'";

                        if($password_get_run = @mysql_query($password_get)){

                            if(mysql_num_rows($password_get_run) > 0){          

                                if(($emailtb != '' && $confirmtb != '-') || ($emailtb != '-' && $confirmtb != '-')){

                                    if($emailtb == $confirmtb){

                                        if(preg_match("/^[A-Z0-9._%-]+@[A-Z0-9][A-Z0-9.-]{0,61}[A-Z0-9]\.[A-Z]{2,6}$/i", $emailtb)){

                                            $query = "UPDATE user_info SET `name`='$nametb', `username`='$usernametb', `email`='$emailtb', `about`='$abouttb', `interest`='$interesttb', `dream`='$dreamtb', `like`='$liketb', `school`='$schooltb', `schoolyr`='$schoolyrtb', `occupation`='$occupationtb', `occupationyr`='$occupationyrtb' WHERE id='$user_id'";

                                            if($query_run = @mysql_query($query)){

                                                echo 'info successfully updated';
                                            }
                                            else{

                                                echo 'Failiure in updating info';
                                            }

Answer 1

您的SQL语法有错误;查看与您的MySQL服务器版本相对应的手册，以便在附近使用正确的语法 ='嘿那里'，school =' - '，schoolyr =' - '，占用='Chitchat CEO' ，占领'第1行

然后您的第二个SQL错误是您使用保留的SQL关键字作为列名。你需要用反引号引用这个：

 SELECT ...   `like` = '$var'

再次注意反击。

如果您不知道哪些列名可能是特殊名称，那么引用它们是最安全的。（不是一般性建议，但对于新手。）

Answer 2

你错过了'$ schoolyrtb'和职业之间的逗号： , schoolyr='$schoolyrtb' occupation='$occupationtb'。

但您也可以使用

找到这些错误

    else{
       echo 'Failiure in updating info, error: ' . mysql_error();
    }

php代码没有成功执行
