我目前正在进行实时搜索，效果很好，当人们看到实时搜索的结果时，会出现“编辑、删除和查看”三个链接
当我试图通过单击删除链接从数据库中删除一个产品信息时，但问题是它没有做任何事情，甚至根本没有显示错误......
我显示 url 地址末尾没有 product_id 编号查看完整的 url ...
http://localhost/shopone/admin/live/search-save.php?deleteid=
我在代码中错过了什么？
本部分用于从搜索文本字段中获取结果。
<?php
if(isset($_POST['kw']) && $_POST['kw'] != '')
{
$kws = $_POST['kw'];
$kws = mysql_real_escape_string($kws);
$query = "select * from product where product_name like '%".$kws."%' limit 10" ;
$res = mysql_query($query);
$count = mysql_num_rows($res);
$i = 0;
if($count > 0)
{
while($row = mysql_fetch_array($res))
{
$product_id = $row["product_id"];
//Contanter
echo " <div class='container'>";
//First columns Product Images
echo "<div class='sidebar1'>";
echo "<div>";?><a href='$row[$product_name]'><img src="<?php echo $row["screenshot"];?>" width="100" height="100" /></a>

echo "</div>";

echo $row['product_name'];"</div>";

echo "<a href='../data/edit_product.php?pid=' . $product_id . ''>Edit</a>
<a href='search-save.php?deleteid=' . $product_id . ''>Delete</a>
<a href='../data/edit-view.php?pid=' . $product_id . ''>View</a>";
echo "</div>";
//End of Container
echo "</div>";
$i++;
if($i == 5) break;
}
echo "</ul>";
if($count > 5)
{
echo "<div id='view_more'><a href='#'>View more results</a></div>";
}
}
else
{
echo "<div id='no_result'>No result found !</div>";
}
}
?>
此部分用于按删除时删除....
<?php
//Delete Item Question to Admin, and Delete Product if they choose
if (isset($_GET['deleteid'])) {
echo 'Do you really want to delete product with ID of ' . $_GET['deleteid'] . '? <a href="search-save.php?yesdelete=' . $_GET['deleteid'] . '">Yes</a> | <a href="search-save.php">No</a>';
exit();
}
if (isset($_GET['yesdelete'])) {
//remove item from system and delete its picture
//delete from database
$id_to_delete = $_GET['yesdelete'];
$sql = mysql_query("DELETE FROM product WHERE product_id='$id_to_delete' LIMIT 1") or die (mysql_error());
/////////////////////////////////////////////////////////////
// unlink the image from server
// Remove The Pic -------------------------------------------

$pictodelete = ("../product_images/$id_to_delete.jpg");
if (file_exists($pictodelete)) {
unlink($pictodelete);
}
}
?>
