Bitrix ЧПУ Catalog.smart.filter: Remove Parameters & Add /apply/

Hey guys! Let's dive into the fascinating world of Bitrix and its catalog.smart.filter component. Specifically, we're going to tackle a common challenge: customizing the SEO-friendly URLs (ЧПУ) generated by this component. If you've ever wrestled with complex URL structures and wished for more control, you're in the right place. We'll explore how to manipulate these URLs, focusing on removing specific parameters and adding custom elements. Trust me, mastering this will significantly enhance your site's SEO and user experience.

Understanding ЧПУ and the catalog.smart.filter Component

First things first, let's break down what we're dealing with. ЧПУ, or человеко-понятные URL (human-friendly URLs), are URLs designed to be easily readable by both humans and search engines. They typically include descriptive keywords that reflect the content of the page, making them SEO gold. The catalog.smart.filter component in Bitrix is a powerful tool for creating dynamic filters in your product catalogs. It allows users to narrow down products based on various criteria, such as price, color, size, and more. However, the default URL structure it generates might not always be ideal, especially when you want a cleaner and more optimized URL.

The default URLs generated by the catalog.smart.filter component often include parameters that, while functional, can clutter the URL and make it less user-friendly. Parameters like is-from-to-or and others, while technically necessary for the filtering logic, don't contribute much to the URL's readability or SEO value. This is where customization comes into play. We want to strip away the unnecessary bits and create URLs that are concise, descriptive, and easy to share. This involves digging into the component's class and tweaking its URL generation logic, which might sound daunting, but we'll break it down step by step.

Furthermore, adding custom elements like /apply/ can provide better control over how filters are applied and how the URLs are structured. This not only improves the user experience by making the filter application explicit but also gives us more flexibility in managing the URL structure. By customizing the URLs, we can ensure that they accurately reflect the filtered content and are optimized for search engines. This is a critical aspect of SEO, as clean and descriptive URLs can improve a site's ranking and click-through rates. So, let's get our hands dirty and start exploring how to make these changes!

The Challenge: Modifying URL Parameters

The core challenge we're addressing today is how to surgically remove specific parameters from the URLs generated by the catalog.smart.filter component. Imagine you have a URL that looks something like this: /catalog/products/?color=red&price-from=100&price-to=200&is-from-to-or=1. It's functional, but let's be honest, it's not the prettiest or most SEO-friendly URL. We want to transform it into something cleaner, perhaps like /catalog/products/color-red/price-100-200/. The key here is identifying the parts we want to remove, like the is-from-to-or parameter, and implementing the logic to exclude them from the URL generation process.

Removing parameters like is-from-to-or requires a deep dive into the component's code. This parameter often represents a logical condition for handling price ranges or other numerical filters. While it's essential for the component's internal workings, it doesn't need to be exposed in the URL. By removing it, we can significantly simplify the URL structure. This involves understanding the component's class structure and identifying the methods responsible for generating the URLs. Once we've located the relevant code, we can modify it to exclude the unwanted parameters. This might involve conditional checks or string manipulation techniques to filter out the specific parameters we want to remove.

In addition to removing parameters, we might also want to add custom elements to the URL, such as the /apply/ suffix. This can be useful for explicitly indicating that a filter has been applied. It also provides a clear separation between the base URL and the filter parameters, making the URL easier to parse and understand. Implementing this involves modifying the URL generation logic to append the /apply/ suffix when filters are active. This might seem like a small change, but it can have a significant impact on the overall clarity and structure of the URLs. So, let's roll up our sleeves and dive into the code to make these changes happen!

Diving into the Bitrix Component Class

Okay, folks, let's get technical! To achieve our URL customization goals, we need to venture into the heart of the catalog.smart.filter component's class. This is where the magic happens – where the URLs are generated and the filtering logic is processed. The first step is locating the component's class file. In Bitrix, component classes are typically found in the /bitrix/components/ directory, under the component's namespace (e.g., bitrix:catalog.smart.filter). Once you've located the class file (usually a PHP file), open it up in your favorite code editor. Brace yourselves; we're about to do some code spelunking!

Inside the component class, we need to identify the methods responsible for generating the URLs. This often involves looking for methods that handle filter parameters and construct the URL string. Common methods to investigate might include those related to prepareResult, getResult, or any methods that explicitly deal with URL manipulation. Pay close attention to how the component processes filter parameters and constructs the URL based on those parameters. This is where we'll need to make our modifications. Understanding the flow of data and the logic behind URL generation is crucial for making the right changes.

Once you've identified the relevant methods, it's time to start thinking about how to modify them. This might involve adding conditional checks to exclude specific parameters, using string manipulation techniques to remove unwanted parts of the URL, or adding custom elements like the /apply/ suffix. Remember, the goal is to modify the URL generation logic without breaking the component's functionality. So, it's essential to test your changes thoroughly to ensure that the filters still work as expected and that the URLs are generated correctly. This might involve setting up a development environment and testing the changes in isolation before deploying them to a live site. So, let's dig into the code and start customizing those URLs!

Code Modifications: Removing and Adding Parameters

Alright, code warriors, let's get down to the nitty-gritty! We're at the point where we'll be making actual modifications to the component's code. This is where our understanding of the component's class and URL generation logic comes into play. Our primary goal is to remove the is-from-to-or parameter and add the /apply/ suffix. We'll tackle these tasks one at a time, ensuring that each modification works as expected.

First, let's focus on removing the is-from-to-or parameter. We'll need to locate the section of code where the URL is being constructed and filter out this specific parameter. This might involve adding a conditional check within a loop that iterates over the filter parameters. For example, you might add an if statement that checks if the parameter name is is-from-to-or and, if so, skips adding it to the URL. Alternatively, you could use array manipulation techniques to remove the parameter from the array of filter parameters before the URL is constructed. The key is to ensure that this parameter is excluded from the final URL without affecting the functionality of other filters. Remember to test this thoroughly to ensure that price range filters and other similar filters still work correctly.

Next up, let's add the /apply/ suffix. This is a relatively straightforward modification. We simply need to append this suffix to the URL after all the filter parameters have been processed. This might involve adding a line of code that concatenates the /apply/ string to the end of the URL. However, we need to be careful to add this suffix only when filters are active. We don't want to append /apply/ to the base URL when no filters have been selected. This might involve adding a conditional check to ensure that the suffix is only added when there are filter parameters in the URL. Again, thorough testing is crucial to ensure that the suffix is added correctly and doesn't break any existing functionality. So, let's dive into the code and make these modifications happen!

Testing and Implementation

Okay, guys, we've made some significant changes to the component's code. Now comes the crucial step: testing and implementation. No matter how confident we are in our code modifications, thorough testing is essential to ensure that everything works as expected. This is our safety net, our chance to catch any bugs or unexpected behavior before deploying the changes to a live site. So, let's put our code through its paces!

The first step in testing is to set up a development environment. This is a safe space where we can experiment with our code without affecting the live site. A development environment is essentially a copy of your website, complete with the database and files. This allows us to make changes, test them, and fix any issues without any risk to the live site. Once we have our development environment set up, we can start testing our modifications.

The testing process should be systematic and comprehensive. We need to test all the scenarios that our modifications might affect. This includes testing different filter combinations, ensuring that the is-from-to-or parameter is indeed removed, and verifying that the /apply/ suffix is added correctly. We should also test the component's behavior when no filters are selected to ensure that the base URL remains clean. If we encounter any issues during testing, we can use debugging tools to identify the root cause and fix the code. This might involve stepping through the code line by line, examining variable values, and tracing the execution flow.

Once we're confident that our modifications are working correctly in the development environment, we can proceed with implementation on the live site. This typically involves copying the modified component files to the live site and clearing the Bitrix cache. It's always a good idea to back up your site before making any changes, just in case something goes wrong. After deploying the changes, we should perform a final round of testing on the live site to ensure that everything is working as expected. And there you have it! We've successfully customized the catalog.smart.filter component's URLs, making them cleaner, more SEO-friendly, and easier to manage.
