php - 单个 PHP 上的多种表单

Question

我正在尝试在 PHP 文件上创建两个表单。处理PHP代码位于同一页面上，但我不知道如何将表单1连接到代码1，将表单2连接到代码2。我知道这可能是一个非常基本的问题，但我不知道该怎么做它..谢谢!这是我的代码(我只发布重要部分，而不是连接等)

    <div class="persinfo">

<?php

$bday = $_POST['bday']; 
$sex = $_POST['sex'];  
$flighttime = $_POST['flighttime'];
$country = $_POST['country'];

$sqlupdate = "SELECT * FROM users WHERE username='$u' AND activated='1'";
$user_query = mysqli_query($db_conx, $sqlupdate);

mysqli_query($db_conx,"UPDATE users SET country='$country', bday='$bday', sex='$sex', flighttime='$flighttime' WHERE username='$u' ");

?>

    <form method="post" /> 

        <p><span>Country: </span> <input type="text" name="country" id="country" value="<?php echo $country; ?>"></p>
        <p><span>Gender: </span>
            <select name="sex" id="sex">
                <option>Male</option>
                <option>Female</option>
            </select></p>
        <p><span>Birthday: </span><input type="date" name="bday" id="bday" value="<?php echo $bday; ?>"></p>
        <p><span>Flight experience: </span>
            <select name="flighttime" id="flighttime">
                 <option>0-500</option>
                 <option>500-1000</option>
                 <option>1000-5000</option> 
                 <option>5000 +</option>    
            </select></p>

         <p><input  name="submit_profile" type="submit" value="Save"></p>

    </form>


    </div>

         <p><input  name="submit_lic" type="submit" style="margin: 0 auto; width:100px;" value="Save"></p>

    </form>

    </div>

Answer 1

通常的方法是使用一个隐藏的输入字段来指定每个表单的形式。例如:

<form id="Form1">
    <input type="text" name="formName" value="form1" hidden />
    <!-- add the rest of inputs for the form -->
</form>

<form id="Form2">
    <input type="text" name="formName" value="form2" hidden />
    <!-- add the rest of input for the form -->
</form>

然后在你的 PHP 中:

$formName = $_GET['formName'];

if($formName === 'form2'){
    // do something for form2
}else{
    // do something for form1
}

注意

我在您的代码中注意到的一点是，它相当容易受到称为“SQL 注入(inject)”的攻击类型的攻击。基本上，通过直接将 $_POST 中的数据放入 SQL 查询中，攻击者就有可能将恶意脚本插入到输入字段中。如果这最终要成为现场形式，则需要注意一些事情。
