我有一个基本的管理面板，我可以看到所有供应商和所有已添加的产品。在供应商页面中，我想添加一个链接，当单击该链接时，将仅显示/添加/编辑该供应商的产品。有关如何做到这一点的任何线索？
************编辑**************
这就是我的产品页面的样子。此页面显示所有产品。

这就是我所谓的上述页面的链接：
<?php
$sel=mysql_query("select * from offers where OfferID='".$id."'") or die(mysql_error());
$fet=mysql_fetch_array($sel);
$rest=mysql_query("select * from restaurants where RestID='".$fet['RestID']."'") or die(mysql_error());
$restfet=mysql_fetch_array($rest);
$dd= $fet['Links'];
$rest_id=$fet['RestID'];
$sql_mlink=mysql_query("select * from offers where off_status='Y' and OfferID!='".$id."' and RestID='".$rest_id."' order by OfferID asc") or die(mysql_error());
$sql_query = mysql_query("SELECT * FROM offers where RestID='".$res['RestID']."'");
$row = mysql_fetch_array($sql_query);
//$res_count=mysql_num_rows($row);
$sy = mysql_query("SELECT * FROM offers where RestID='".$res['RestID']."' and status='Y'");
$res_count=mysql_num_rows($sy);
$rw = mysql_fetch_array($sy);
?>
<td class="table_text">
<a href="view_offers.php?rest_id=<?php echo $row['RestID']; ?>" target="_blank">Menu</a>
</td>

你应该能够很容易地使用php获取并轻松调整你的SQL。
将供应商编号/转义名称添加到此页面的链接末尾...例如：
<a href='this-page.php?vendor=vendor-1'>vendor 1</a>
然后在页面的开头检查是否有供应商集，如果有，请为您的语句末尾创建一些额外的sql。如果不将额外的sql变量留空，则不添加任何内容：
if(!empty($_GET['vendor']))
{
$extra_sql = " AND vendor = ".$_GET['vendor'];
}
else
{
$extra_sql = "";
}
然后将$ extra_sql变量添加到现有SQL的末尾：
$rest=mysql_query("select * from restaurants where RestID='".$fet['RestID']."'".$extra_sql) or die(mysql_error());
