PHP ADODB生成下拉列表框功能示例

<?php
  include_once ('../adodb5/adodb.inc.php');
  $conn = ADONewConnection('mysql');
  $conn -> PConnect('localhost','root','root','db_database14');
  $conn -> execute('set names gb2312');
  $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC;
?>

<?php
include_once 'conn/conn.php';
$sqlstr = 'select bigclass,id from tb_object';             //sql查询语句
$rst = $conn -> execute($sqlstr) or die('execute error: '.$conn -> errorMsg()); //执行查询语句，返回结果集
?>
<!-- 提交表单 -->
<form method='post' action=''>
  请选择购买商品的类别
<!-- 调用getMenu()函数 -->
  <?php echo $rst -> getMenu('bigclass'); ?>
  <input type='submit' name='submit' value='提交' />
</form>
<!-- ---------------- -->
<?php
if(isset($_POST[bigclass])){                    //判断表单是否被提交
  echo '您选择的商品类别是'.$_POST[bigclass];         //输出提交的表单值
}
?>
