Question

我有一个运行MySQL查询并返回一些数据的php脚本。我想要做的是通过下拉列表控制返回的结果。

下拉列表需要在其中包含以下信息供学生选择。

SELECT courseid FROM course_students WHERE userid = $ user

以下是我当前的代码.....我试图弄清楚如何将上述内容与之合并：

    <?php
defined('_JEXEC') or die;

$db = JFactory::getDBO();
$user = & JFactory::getUser();
$userid = $user->get('id');
$course = "SELECT 
  c.coursename
FROM
  courses AS `c`  
  LEFT OUTER JOIN course_students AS s 
    ON s.courseid = c.id 
WHERE s.userid = '1285'";
$courses= mysql_fetch_array($course);
?>
Please Select Course for Results:
<select> 
<?php foreach($courses as $c){ 
   echo "<option value='$c'>".$c."</option>";
} ?>
</select>
<?php
$sql =
    "SELECT 
  as.name,
  DATE_FORMAT(s.starttime, '%b %d, %Y %H:%i') AS TIME,
  s.totalhours AS hrs 
FROM
  clinicalsites AS `as` 
  LEFT OUTER JOIN clinical_dashboard AS s 
    ON s.clinicalsite = as.id 
WHERE s.userid = $userid 
  AND starttime > NOW()
AND courseid = $c";

$db->setQuery($sql);

$rows = $db->loadObjectList();
?>
<style>
    table, td, th
    {
        border-bottom:1px solid black;
        text-align:center;
    }
    th {
        background-color:#000000;
        color: #FFF;
    }


    .upcoming {
        font-weight: bold;
    }
    .complete {
        font-weight: bold;
        color: #060;
    }
    .pending {
        font-weight: bold;
        color: #F00;
    }
    .approved {
        color: #C60;
    }
</style>

以下是使用select的下拉查询。

$course = "SELECT 
  c.coursename
FROM
  courses AS `c`  
  LEFT OUTER JOIN course_students AS s 
    ON s.courseid = c.id 
WHERE s.userid = '1285'";
$courses= mysql_fetch_array($course);
?>
Please Select Course for Results:
<select> 
<?php foreach($courses as $c){ 
   echo "<option value='$c'>".$c."</option>";
} ?>
</select>

Answer 1

我相信你需要这样的东西

<select> 
<? foreach($courses as $c){ 
   echo "<option value=".$c['table_id'].">".$c['coursename']."</option>";
} ?>
</select>

祝你好运！

同时在查询中选择表ID，以便将其用作“选项”

的值

将列表选择器添加到mysql查询
