甚至专家PHP不能回答你的问题...... – user1844933

开放数据库连接，建立查询，执行查询？我没有看到问题在这里。 –

<?php 
include("dbconfig.php"); 
if(isset($_POST['submit'])) 
{ 
    if(isset($_POST['type'])) 
    { 
     if($_POST['type'] == "enquiry") 
     { 
      Query 
     } 
     elseif($_POST['type'] == "enroll") 
     { 
      Query 
     } 
     else 
     { 
      echo "Please select enquiry or enrollment"; 
     } 
    } 
    else 
    { 
     echo "Please select an option"; 
    } 

} 

?> 
<form action="dropd.php" method="POST"> 
<select name="type"> 
<option value="">Please select:</option> 
<option value="enquiry">Student enquiry</option> 
<option value="enroll">Student enrollment</option> 
<input type="submit" name="submit" value="SUBMIT"> 
</select> 
</form>

在这个答案中，HTML部分存在错误，不知道它是如何有用的。 –

您的代码应该是这样的：

<?php 
include("dbconfig.php"); 
if(isset($_POST['submit'])){ 
    if(isset($_POST['type']) && $_POST['type'] == "enquiry") 
    { 
    query for enuiry; 

    } else { 
    query for enroll; 
    } 
} 
?> 
<form action="dropd.php" method="POST"> 
<select name="type"> 
    <option value=''>Please select:</option> 
    <option value="enquiry">Student enquiry</option> 
    <option value="enroll">Student enrollment</option> 
</select> 
<input type="submit" name="submit" value="SUBMIT"> 
</form>
