我有一个个人资料表格，用户只保留一份记录，并且可以随时更新他们的信息。首先，我可以使用 mysql update 来更新一个空表吗？我正在尝试设置提交以执行两个功能。插入或更新，取决于记录是否存在：

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，并且不会给出任何错误。任何想法表示赞赏。

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){

还有我的表格...

<form id="profile" action="{$HTTP_HOST}admin/profile.php" method="post" autocomplete="off">

和按钮：

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

谢谢。

从哪里来$profile['user_id']？如果您事先有此值，则您必须已经知道用户是否存在，因此相应地调用插入或更新。

如果您认为您可能已经$profile['user_id']正确定义并且表中不存在此类用户，那么您的应用程序的其他位置可能存在逻辑问题。您始终可以通过简单的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'] . "'"

不，您不能更新空表，您必须有一条要更新的记录。

您对基本 mysql 查询有另一个抽象级别，因此除非您发布插入/更新函数的功能，否则我们无法真正帮助您。

无论如何只需检查记录是否存在，如果存在，则更新记录，如果不插入。
