【问题描述】：

我有一个名为 editdetails.php 的页面，在该页面上，用户可以通过选择选项来编辑他们的详细信息，例如宗教、教育、爱好等。我已经完成了 HTML，但是我如何将 INSERT/UPDATE 放入名为 @ 的数据库中987654327@，其中包含用户详细信息，例如username、password、profile_pic、about_me。

我希望将详细信息更新到users 表中，并且我想在他们选择选项后在他们的个人资料中回显它。代码如下：

<?php include("inc/header.inc.php");
$updateinfo =@$_POST['updateinfo'];
    //This is what I want to echo on their profile
    $get_info = mysql_query("SELECT relationship, height, body_type, hair_color, eye_color, smokes, drinks, religion, children, living, education, job FROM users WHERE username='$user'");
    $get_row = mysql_fetch_assoc($get_info);

    $db_relationship =$get_row['relationship'];
    $db_height =$get_row['height'];
    $db_body_type =$get_row['body_type'];
    $db_hair_color =$get_row['hair_color'];
    $db_eye_color =$get_row['eye_color'];
    $db_smokes =$get_row['smokes'];
    $db_drinks =$get_row['drinks'];
    $db_religion =$get_row['religion'];
    $db_children =$get_row['children'];
    $db_living =$get_row['living'];
    $db_education =$get_row['education'];
    $db_job =$get_row['job'];
 ?>
<?php
if ($updateinfo) {
    //variables for submitted data
    $relationship = @$_POST['relationship'];
    $height = @$_POST['height'];
    $body_type = @$_POST['body_type'];
    $hair_color = @$_POST['hair_color'];
    $eye_color = @$_POST['eye_color'];
    $smokes = @$_POST['smokes'];
    $drinks = @$_POST['drinks'];
    $religion = @$_POST['religion'];
    $children = @$_POST['children'];
    $living = @$_POST['living'];
    $education = @$_POST['education'];
    $job = @$_POST['job'];

    //submit details to database
   //Guys this is where my problem is should I INSERT INTO 'users' or   UPDATE 'users'    
 $info_submit_query = mysql_query("UPDATE users SET relationship='$relationship', height='$height', body_type='$body_type', hair_color='$hair_color', eye_color='$eye_color', smokes='$smokes', drinks='$drinks', religion='$religion', children='$children', living='$living', education='$education', job='$job'");
echo "<div class='alert alert-success'>Your profile information has been updated</div>";
    }
    else
    {
        //do nothing
    }
?>

【问题讨论】：

DANGER! You need to prevent SQL Injection! 拜托，stop using mysql_* functions。 它们不再维护，而是 officially deprecated。 了解prepared statements，然后使用PDO。
启动和使用mysql_* 函数的人数之多令人惊讶。我想知道问题是否在于这些机构没有更新他们的学习材料和教授旧的（和过时的）理论
顺便说一句，另一个大问题：您的update 语句缺少where 子句，因此您将使用新信息更新所有用户记录。
除此之外：您的问题被严重否决，因为您似乎希望有人为您完成工作（即使这种解释可能只是取决于您如何表达问题）。在 Stack Overflow 上，免费工作的请求往往不会被很好地接受 - 我建议您寻求帮助，强调您愿意根据所提供的任何帮助进行必要的实施。

【解决方案1】：

在解决了 Jay Blanchard 告诉您的所有问题（它们应该是您的首要任务）以及我自己发表的评论（关于清理您的 SQL）之后，您可以尝试这样做：

INSERT INTO users ( column_name1, column_name2, .... )
VALUES ( value1, value2, .... )
ON DUPLICATE KEY 
UPDATE column_name1 = value1, column_name2 = value2, ....

这会将新值插入数据库，如果记录已经存在，它将更新它。你可以找到more information on the MySQL web site。
