我需要在我的网站上过滤不同类别的产品。例如，如果您选择类别“饮料”，它将显示属于该类别的产品

为了更好地解释我自己

我需要按类别过滤我网站的出版物[产品]，例如，当选择一个类别时，比如说“饮料”，只显示属于该类别的出版物[产品]

数据库[图像]

类别

发布[产品]

<?php include($_SERVER['DOCUMENT_ROOT'].'/app/controllers/products.php');
include('app/includes/categories.php');
$categorias = selectAll('categories');
$capitulos = selectAll('products');

<div class="productos-list">
    
<?php foreach ($productos as $key => $producto): ?>           
<ul>
    <a href="/ver/productos.php?id=<?php echo $producto['id']?>">
    <li class="producto-name"><?php echo $producto['name']?></li>
    </a>
</ul>
<?php endforeach; ?> 
    </div>

例如，选择“饮料”类别时，仅显示标有此类别的产品，在本例中为“产品”

这是我目前的代码：

在categories.php[index]中显示产品的代码

<?php include($_SERVER['DOCUMENT_ROOT'].'/app/controllers/products.php');
include('app/includes/categories.php');
$categorias = selectAll('categories');
$capitulos = selectAll('products');

<div class="productos-list">
    
<?php foreach ($productos as $key => $producto): ?>           
<ul>
    <a href="/ver/productos.php?id=<?php echo $producto['id']?>">
