Question

我有一个个人资料表单，用户只保留一个记录，并可以随时更新他们的信息。首先，我可以使用mysql更新来更新空表吗？我正在尝试设置提交以执行两个功能。插入或更新，具体取决于是否存在记录：

if(isset($_POST['update']) && $profile['user_id'] == ""){
    DB::getInstance()->insert_profile(
        $_POST['user_id'], 
            $_POST['fname'], 
        $_POST['mname'], 
        $_POST['lname'], 
        $_POST['profilepic'], 
        $_POST['location'],
        $_POST['tag'], 
        $_POST['email'],
        $_POST['confemail'],
        $_POST['newsletter'], 
        $_POST['height'], 
        $_POST['build'],
        $_POST['eyecolour'], 
        $_POST['haircolour'], 
        $_POST['race'], 
        $_POST['nationality'], 
        $_POST['languages'],
        $_POST['playingage'], 
        $_POST['accents'], 
        $_POST['aname'], 
        $_POST['aagency'], 
        $_POST['atelephone'],
        $_POST['aemail'], 
        $_POST['aweb'], 
        $_POST['facebook'], 
        $_POST['twitter'], 
        $_POST['spotlight'],    
        $_POST['castingcall']);
}

else if (isset($_POST['update']) && $profile['user_id'] != ""){
hcDB::getInstance()->update_profile(
        $_POST['user_id'], 
        $_POST['fname'], 
        $_POST['mname'], 
        $_POST['lname'], 
        $_POST['profilepic'], 
        $_POST['location'],
        $_POST['tag'], 
        $_POST['email'],
        $_POST['confemail'], 
        $_POST['newsletter'], 
        $_POST['height'], 
        $_POST['build'],
        $_POST['eyecolour'], 
        $_POST['haircolour'], 
        $_POST['race'], 
        $_POST['nationality'], 
        $_POST['languages'],
        $_POST['playingage'], 
        $_POST['accents'], 
        $_POST['aname'], 
        $_POST['aagency'], 
        $_POST['atelephone'],
        $_POST['aemail'], 
        $_POST['aweb'], 
        $_POST['facebook'], 
        $_POST['twitter'], 
        $_POST['spotlight'],    
        $_POST['castingcall']);
}

这不起作用，并且不会出现任何错误。任何想法都表示赞赏。

很抱歉这是我的插入和更新功能：

public function update_profile (
$userID,$fname, $mname, $lname, $profilepic, $location, $tag, $email, $confemail, $newsletter,
$height, $build, $eyecolour, $haircolour, $race, $nationality, $languages,
$playingage, $accents, $aname, $aagency, $atelephone, $aemail, $aweb,
$facebook, $twitter, $spotlight, $castingcall){

和我的表格......

和按钮：

<button class="submit" type="submit" value="update" name="update">Update</button>

感谢。

Answer 1

不，你不能更新空表，你必须有一个你想要更新的记录。

你对基本的mysql查询有另一层次的抽象，所以除非你发布你的插入/更新函数所做的事情，否则我们无法真正帮助你。

无论如何只检查是否存在记录，如果存在，则更新记录，如果没有插入。

Answer 2

$profile['user_id']来自哪里？如果您事先拥有此值，则必须已知道用户是否存在，因此请相应地调用insert或update。

如果您认为可能已正确定义$profile['user_id']并且表中不存在此类用户，则您的应用程序的其他位置可能存在逻辑问题。您始终可以使用简单查询检查该用户是否存在：

"SELECT user_id 
    FROM your_user_table 
    WHERE user_id = '" . (int)$profile['user_id'] . "'"

更新空表的形式
