Hi, I’m a full‑stack developer with over 5 years of experience building custom solutions in PHP, Node and React, and I’ve spent a lot of time extending OpenCart for niche e‑commerce needs. Converting your auto‑parts filter from OpenCart 2.x to 3.0.5 is right up my alley. I’ll start by pulling the current 2.x extension, mapping its controllers, models and view templates to OpenCart 3’s revamped MVC‑L structure. The vehicle‑model filter logic will be ported and refactored to use the newer event system, while I’ll add the necessary joins so products are correctly linked through their categories. A quick set of unit tests and a sandbox install will let us verify that the filters work exactly as they did before, but now on the 3.0.5 core. Do you have any custom modifications or a particular category hierarchy that we need to respect during the migration? Also, could you share the PHP version your server runs so I can align the code accordingly? Looking forward to getting this extension running smoothly on OpenCart 3. Thanks.

Hi, I have solid experience working with OpenCart 2.x and 3.x, including custom extensions and module upgrades. I can efficiently convert your auto-parts filter extension from OpenCart 2.x to 3.0.5.0, ensuring full compatibility with the updated structure (OCMOD/events, controllers, and Twig templates). I will also handle proper product-to-category linking so the filtering works accurately based on car models, maintaining performance and clean logic. The upgraded module will be tested thoroughly to ensure it integrates smoothly with your current store. Code will be clean, well-structured, and easy to maintain, with no conflicts with other extensions. I can start immediately and complete this quickly with reliable results.

Hey — saw your post about converting your OpenCart 2.x Avtofilter extension to work on 3.0.5.0. The main headache here is usually not the code itself, but making sure all events, admin settings, and front-end filters survive the 2.x → 3.x changes without breaking the catalog. Quick question before I suggest an approach: Do you have the original extension files (both admin + catalog + ocmod/vqmod) and is it currently running fine on your 2.x store? I’ve ported several custom and marketplace extensions from OpenCart 2.x to 3.x, including modules with complex filters and SEO-friendly URLs. If you can send the extension archive and a link to your 3.0.5.0 store (or test site), I’ll review them and tell you exactly what needs changing and what’s realistic.

Hi there! Does the extension need to support multi-store setups or just a single store installation? Regardless, this is definitely something that I feel confident delivering on, given my past experience. I would love to discuss your project further! Looking forward hearing from you.

I can help you port your existing OpenCart 2.x Avtofilter extension to OpenCart 3.0.5.0, ensuring full compatibility with the new architecture and event system while preserving all current functionality. I’ve worked on multiple OpenCart migrations and custom extensions, including upgrades from 1.5/2.x to 3.x, resolving issues around namespaces, OCMOD changes, and admin/catalog adjustments. This experience helps prevent common upgrade bugs and maintain stable performance. My approach will be to review the current extension code, adjust it for OpenCart 3 standards, update installation and language files, then test thoroughly on a 3.0.5.0 environment to confirm everything works as expected. I would love to chat more about your project! Regards

I already see a clean way to execute this. I specialize in OpenCart custom development and version upgrades, including porting extensions from 2.x to 3.x while keeping all core functionality intact. I’ve handled similar migrations before, so updating your Avtofilter extension to work smoothly on OpenCart 3.0.5.0 is very much in my lane. You want your existing 2.x Avtofilter extension to run reliably on 3.0.5.0 without breaking your store, losing features, or causing conflicts with your current theme and other modules. My approach would be to review the current extension code, adjust it for OpenCart 3’s structure and event system, then test it on a safe environment before providing you with a clean, installable 3.0.5.0-ready version. Quick question before I suggest next steps: do you have any custom modifications or theme overrides tied to the current Avtofilter extension? Lets chat more about your project, worst case you walk away with a free strategy session Regards

Hey — saw your post about converting an OpenCart 2.x extension (Avtofilter) to work on OpenCart 3.0.5.0. The main headache here is usually changes in the event/system structure and compatibility with the newer admin/theme layout. Quick question before I suggest an approach: Do you already have the original Avtofilter source code and a test copy of your 3.0.5.0 store to work on, or is this a live-only setup? I’ve ported several custom OpenCart 1.5/2.x extensions to 3.x, including filters and catalog-side modules, so I’m familiar with the usual migration issues. If you send the extension files (OCMOD/VQMod) and a link or brief spec of how you’re using it now, I can review and outline exactly what needs to change.

Hey — saw your post about porting the Avtofilter extension from OpenCart 2.x to 3.0.5.0. The main headache here is usually not the code itself, but catching all the small API and event/OCMOD changes so nothing silently breaks in admin or frontend. Quick question before I suggest an approach: Do you already have this running on a test OpenCart 3.0.5 store, or are we starting from a clean install? I’ve migrated and fixed several custom OpenCart 2.x extensions to 3.x, including filters and product modules, so I’m familiar with the version-specific quirks. If you send the current extension files and any notes on customizations, I’ll take a look and tell you exactly what’s involved.
