Question

我想将密码插入数据库现有字段。但这显示错误..

 <?php
    include './DB_Connection/connection.php';
    //some code
    $sql = mysql_query("UPDATE user_info SET password = '$password' WHERE company_name='$company_name' AND email = '$email' ");
            $result = $db->query($sql);
            echo 'out';
            if ($result) {//some cose
       }
    ?>

致命错误：在非对象中调用成员函数query（）第23行的“path”\ password_generation.php

第23行是：$result = $db->query($sql);

Answer 1

  <?php
include './DB_Connection/connection.php';
//some code
 $sql = "UPDATE user_info ". "SET password = $password ". 
           "WHERE company_name = $company_name AND email= $email";
     $result=  mysql_query($sql)
      //  $result = $db->query($sql);
        echo 'out';
        if ($result) {//some cose
   }
?>

Answer 2

删除＆＃39; mysql_query＆＃39;函数，$ db-＆gt; query（）应该得到一个字符串。并且在5.5

中已经弃用了mysql_query

使用php更新mysql数据库现有的feild
