Assuming you have a list of products and each product has a ‘size’ attribute, and you are using a function called search:

Sample list of products

products = [
{‘name’: ‘Product A’, ‘size’: ‘Small’},
{‘name’: ‘Product B’, ‘size’: ‘Medium’},
{‘name’: ‘Product C’, ‘size’: ‘Large’},
# Add more products with size information
]

Function to filter products by size

def filter_by_size(product_list, selected_sizes):
return [product for product in product_list if product[‘size’] in selected_sizes]

Function to perform the search with size filtering

def search_and_filter(query, selected_sizes):
# Call your search function, assuming it returns a list of products
search_results = search(query)

# Filter the search results by selected sizes
filtered_results = filter_by_size(search_results, selected_sizes)

return filtered_results

Example usage

search_query = “your_search_query_here”
selected_sizes = [‘Small’, ‘Medium’]

Call the search and filter function

filtered_results = search_and_filter(search_query, selected_sizes)

Display the filtered results

print(“Filtered Results:”)
for product in filtered_results:
print(product)

In this example, the filter_by_size function takes a list of products and a list of selected sizes, and it returns a new list containing only the products that match the selected sizes.

The search_and_filter function calls your existing search function and then filters the results using the filter_by_size function based on the selected sizes.

Adjust the code according to your specific implementation details and the structure of your product data.

You forgot to tell ChatGPT to use PHP.

How can you filter by size if your model does not have anything related to its size?

Furthermore, if your choices are mutually exclusive (as it seems) use radio buttons instead of check boxes.
