我有4个数据库表。从下拉菜单中选择星期一后，将插入到“表1”，从下拉菜单中选择星期二后，将插入到“表2”，依此类推。请告诉我怎么做。。。我在这方面很新。请欣赏我愚蠢的错误

谢谢。

将菜单放入表单中，以便提交其值：

<form action="insert.php" method="post">
Name: <input type="text" name="Name">
First Name: <input type="text" name="FirstName">
SID: <input type="int" name="SID">
Email: <input type="text" name="Email">
<select name="day">
    <option id="mon" value="1"></option>
    <option id="tue" value="2"></option>
    <option id="thu" value="3"></option>
    <option id="fri" value="4"></option>
</select>
<input type="submit">
</form>

将名称添加到“选择”：

<select name="my_select_name">

但是请注意，在将从用户检索到的数据插入数据库之前，您不会对其进行任何筛选，这是非常危险的，并且会导致错误/SQL注入

成功了！谢谢在我的基本工作完成后，我将进行验证！不过谢谢你的建议。。。你太棒了！：）

<form action="insert.php" method="post">
Name: <input type="text" name="Name">
First Name: <input type="text" name="FirstName">
SID: <input type="int" name="SID">
Email: <input type="text" name="Email">
<select name="day">
    <option id="mon" value="1"></option>
    <option id="tue" value="2"></option>
    <option id="thu" value="3"></option>
    <option id="fri" value="4"></option>
</select>
<input type="submit">
</form>

$table = "table" . $_POST['day'];
$sql="INSERT INTO $table (Name, FirstName, SID, Email)
    VALUES
    ('$_POST[Name]','$_POST[FirstName]','$_POST[SID]','$_POST[Email]')";

<select name="my_select_name">

$sql="INSERT INTO table".$_POST['my_select_name']." (Name, FirstName, SID, Email)
