exit;
}

<form id="formid" action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<label>Tribuna :</label> <select name="tribuna" class="tribuna">
<option selected="selected">-Select-</option>
<?php
$sql=mysql_query("select id,tribune_number from tb_tribuna ");
while($row=mysql_fetch_array($sql))

假设“createdb.php”具有正确的数据库连接信息:
$conn = mysql_connect("$host","$db_uid","$db_pwd");
mysql_select_db("$db", $conn);
使您的删除功能如下所示:
$sql = "DELETE FROM tb_tribuna WHERE id = '$_POST[tribuna]' ";
$result = mysql_query($sql, $conn) or die(mysql_error());
您需要将db连接传递给mysql_query。
在你的mysql语句中添加“或者死mysql_error()”,这样当某些东西不起作用时,你会得到一条错误信息,帮助你找出问题所在。
