Question

所以我在搜索栏上遇到了问题。问题是我从数据库中获取了我的产品，当我尝试搜索它们时，搜索栏仅重定向到produkti页面。但这并没有显示我所期望的下拉列表及其不可链接性。

<?php 
include "header.php";

$connect = mysqli_connect("localhost", "root", "majsql", "registration");

if(isset($_POST["add_to_cart"]))
{
	if(isset($_SESSION["shopping_cart"]))
	{
		$item_array_id = array_column($_SESSION["shopping_cart"], "item_id");
		if(!in_array($_GET["id"], $item_array_id))
		{
			$count = count($_SESSION["shopping_cart"]);
			$item_array = array(
				'item_id'			=>	$_GET["id"],
				'item_name'			=>	$_POST["hidden_name"],
				'item_price'		=>	$_POST["hidden_price"],
				'item_quantity'		=>	$_POST["quantity"]
			);
			$_SESSION["shopping_cart"][$count] = $item_array;
		}
		else
		{
			echo '<script>alert("Izdelek je že bil dodan")</script>';
		}
	}
	else
	{
		$item_array = array(
			'item_id'			=>	$_GET["id"],
			'item_name'			=>	$_POST["hidden_name"],
			'item_price'		=>	$_POST["hidden_price"],
			'item_quantity'		=>	$_POST["quantity"]
		);
		$_SESSION["shopping_cart"][0] = $item_array;
	}
}

if(isset($_GET["action"]))
{
	if($_GET["action"] == "delete")
	{
		foreach($_SESSION["shopping_cart"] as $keys => $values)
		{
			if($values["item_id"] == $_GET["id"])
			{
				unset($_SESSION["shopping_cart"][$keys]);
				echo '<script>alert("Izdelek odstranjen")</script>';
				echo '<script>window.location="kosarica.php"</script>';
			}
		}
	}
}

			<br />
			
		</div>
	</div>
	<br />

</html>

<?php
   include "footer.php";
?>

并且在searchbar.php中，我现在拥有

<?php


$conn = mysqli_connect('localhost', 'root', '', 'registration', $tbl_product);

if(!isset($_POST['Išči'])) {
	header("Location:produkti.php");
}

$search_sql="SELECT * FROM tbl_product WHERE name LIKE '%".$_POST['Išči']."%'";
$search_query=mysql_query($search_sql);
if(mysql_num_rows($search_query) != 0)
{
	$search_rs =mysql_fetch_assoc($search_query);
}

?>

预期结果就像当我在搜索栏中编写asus时，它会下拉所有asus产品。在我的示例中，当我单击其中的一个将其重定向到他的页面时，我有3种产品，带有asus的一种将被重定向到页面p1.php。

PHP下拉搜索栏，带有活动链接
