我是 php、html 和 mysql 的新手。我有一个数据库,其中包含他们想要出售产品的用户名、产品和价格。该代码用于带有提交按钮的复选框表单,该按钮的作用类似于价格过滤器,提交时应该回显与相应复选框匹配的用户名、产品和价格。. 如果用户选择标记为“0-25”或“100 及以上”的复选框,并单击提交按钮,它应该会回显拥有该特定价格范围内商品的所有用户。我在网上看过并试图操纵一些接近我所拥有的东西。有人可以帮助我或让我了解如何做到这一点吗?任何帮助表示赞赏
这是我的复选框表单。
<form action="pricefilter.php" method="post">
<br><b>Filter By Price:</b><br><br>
<input type="checkbox" name="$0-$25[]" id="Price" value="0-25"/> $0-$25<br><br>
<input type="checkbox" name="$25-$50[]" id="Price" value="25-50"/> $25-$50<br><br>
<input type="checkbox" name="$50-$100[]" id="Price" value="50-100"/> $50-$100<br><br>
<input type="submit" name="submit" value="Submit" />
</form>
这是我的 php 文件的代码。
<?php
mysql_connect ("localhost", "root","root") or die (mysql_error());
mysql_select_db ("xuswapuser");
$priceFilter = $_GET['priceFilter'];
$filteredResponse = array ();
foreach($priceFilter as $range)
{
if($range == 025)
{
$query = "select * from Books where Price <= 25";
$sql = mysql_query($query);
array_push($filteredResponse, $sql);
}
if($range == 2550)
{
$query = "select * from Books where Price >= 25 AND Price <=50";
$sql = mysql_query($query);
array_push($filteredResponse, $sql);
}
if($range == 5075)
{
$query = "select * from Books where Price >= 50 AND Price <=75";
$sql = mysql_query($query);
array_push($filteredResponse, $sql);
}
if($range == 75100)
{
$query = "select * from Books where Price >= 75 AND Price <=100";
$sql = mysql_query($query);
array_push($filteredResponse, $sql);
}
if($range == 100)
{
$query = "select * from Books where Price >= 100";
$sql = mysql_query($query);
array_push($filteredResponse, $sql);
}
}
