我的提交表单工作正常，但代码中有3个插入查询

让我解释一下原因

“插入查询1”允许将窗体上下拉菜单的选定值插入到数据库表中

插入查询2允许将文本区域框内的值插入到单独的行中

插入查询3允许插入所有其他数据

HTML看起来是这样的（它被包装在一段代码中，但我将只包含几个片段）

下拉菜单：

  <select name="Name" id="">
  <?php
  while ($row = mysql_fetch_array($result)) {
  ?>
<option value="<?php echo $row['Name']; ?>"><?php echo $row['Name']; ?>     </option>
  <?php
} ?>
</select>

插入选定的下拉菜单值：

 //if (isset ($_POST['upload']))
//{
$Name=trim($_POST['Name']);
$ins=mysql_query("INSERT INTO Colleges (Name) VALUES ('$Name')") or die(mysql_error()) ;
if($ins)
{
echo "<br>".$Name."inserted";
}
else
{
echo mysql_error();
}
//}

插入数据库时，将显示多行数据。
1行=学院名称（从下拉菜单中）
第二行=距离文本区域的度数
第三行=所有其他数据

如何将所有insert查询合并到一个查询中，以便只有一行？

您可以使用多个查询将多个sql查询合并到一个查询中

多查询示例

$mysqli = new mysqli("example.com", "user", "password", "database");
$sql = "INSERT INTO table VALUES ('My First Table'); ";
$sql.= "INSERT INTO table VALUES ('My Second Table'); ";
$mysqli->multi_query($sql);

通常，您只构建一个查询

获取每个值并将它们添加到查询中（可能作为参数）

但是，您似乎只有一个表，而不是多个表。您可能希望有一个学院表，然后是另一个表，每个学院都有一行课程

另一种方法是，您的第一个查询返回插入行的唯一id，然后所有其他插入也使用ON DUPLICATE KEY UPDATE子句插入此id。但这将是混乱和缓慢的

编辑

单个查询的示例请注意，我刚刚使用了不推荐使用的mysql_*函数，因为您正在使用这些函数，但您应该切换到mysqli_*函数或PDO。无论是转义数据还是使用参数化查询，这两种方法都非常重要

这将为学院插入一条记录，然后使用mysql_insert_id（）获取插入字段的id字段（假设您有一条）。然后使用此id将每个课程插入到另一个表中，该表列出了每个学院的课程：-

那么您只想在数据库中创建一行？是什么阻止你在最后一个查询中添加'Name'和'BachlorsDegrees'并删除另外两个INSERT查询？@kyeiti-我已经尝试过了。不起作用。我必须将两个查询中的结束括号移到最后一个查询之后，但是当我提交表单时，没有插入任何内容。我如何将其应用到我当前的代码中？
