Hey there, let's figure out why your footer is acting up after selecting categories on shop.php. From what you shared:

• When picking a category with products, the footer shifts up and overlaps the product display area
• Even when selecting an empty category, there's a problem with the footer's positioning

Since you only shared the opening include lines of your code, I’ll need a bit more context to pinpoint the exact issue. Could you share these parts of your code?

• The HTML/CSS for your category selection controls (how users pick categories)
• The product display container (the area that shows products or empty state messages)
• Your footer’s HTML and CSS
• Any layout-related CSS for the main content area (like flexbox/grid settings, positioning, or spacing rules)

Common Culprits to Check Right Now #

While waiting for the full code, here are some frequent causes of this kind of footer issue:

1. Collapsing Content Container
   If your product container doesn’t have a defined min-height or fails to expand with its content (e.g., from un-cleared floats), the footer will move up into empty space. For floated product cards, add a clearfix to the parent:

   .product-wrapper::after {
     content: "";
     display: table;
     clear: both;
   }
   

   Then apply the class to your product container:

   <div class="product-wrapper">
     <!-- Product cards go here -->
   </div>
   

2. Incorrect Footer Positioning
   If your footer uses position: absolute without a position: relative parent, it won’t stay anchored to the bottom of the content. Switch to position: relative for the footer, or if you need fixed positioning, add padding to your main content to avoid overlap:

   footer {
     position: fixed;
     bottom: 0;
     width: 100%;
     height: 60px;
     background: #fff;
   }
   
   .main-content {
     padding-bottom: 70px; /* Match or exceed footer height */
   }
   

3. Unhandled Empty Category State
   When a category has no products, your content area might collapse to zero height. Add an empty state message to keep the container intact:

   <?php if(empty($products)): ?>
     <div class="empty-state">
       <p>No products found in this category.</p>
     </div>
   <?php else: ?>
     <!-- Render product cards -->
   <?php endif; ?>
   

   Style the empty state to take up enough space so the footer stays in place.
