Hello!

The task is completely clear. Transitioning from the "sizes as options" architecture (in OpenCart 2.3) to the "sizes as separate products via the OAP Pro module" architecture (in ocStore 3.0) is the right solution for SEO, but it completely changes the logic of working with non-standard sizes.

Since there is physically no product with the conditional size "163x195 cm" in the database, the algorithm for working through the OAP Pro module needs to be implemented as follows:

Here’s how I propose to implement this on the new platform:

Admin logic: For each mattress model, we define a "base" product (parent in the OAP link). In its card, we activate the checkbox "Allow non-standard size" and set the cost per square meter (or per linear meter, depending on your calculation formula).

Frontend logic (in the product card):

When clicking the "Non-standard size" checkbox, the script blocks the standard size grid of the OAP Pro module.

Two input fields appear: Width (cm) and Length (cm) with validation of minimum/maximum technological limits (for example, from 70 to 200 cm).

As numbers are entered, JavaScript dynamically calculates the cost based on the area formula and displays it to the user.

The standard "Buy" button is replaced: now when clicked, the ID of the base product is sent to the cart, but the entered length/width parameters and the dynamically recalculated cost are hiddenly attached to it.

Logic in the cart and order admin:
through the OCMOD modifier, the system class of the ocStore 3 cart will be refined. In the cart, during checkout, and in the admin panel, the manager will see the base mattress model, but with a clear note in the parameters: "Non-standard size: 165x192 cm" and the correct final cost.

Cost and implementation timeline:
Considering the need for integration with the logic of the third-party OAP Pro module and the redefinition of the standard cart mechanism of ocStore 3:

Development cost turnkey: 20,000 UAH

Completion time: 5–7 working days.

What you will need to start:

Access to the deployed test version of the new site on ocStore 3.0.3.7 (where the OAP Pro module is already installed and configured).

The formula currently used to calculate the price for a non-standard size (fixed price per sq.m., or if there are surcharges for cutting/complexity).

I am ready to implement this functionality carefully and without conflicts with existing modifiers. Expand

Budget: 1001 UAH Deadline: 7 days

Good day, Ilya!

To better understand the task, please clarify:
1. Should the sizes of mattresses remain separate products in the new version of the website, or are they planned to be combined into options?
2. What specific functionality for non-standard sizes needs to be implemented: only visual output or also the logic for calculating cost and availability?
3. Is integration with the existing module required, or are alternative solutions possible?

My approach to the task:
- I will analyze the current implementation on the old version of the website and adapt it to the new product structure on ocStore 3.0.3.7.
- I will ensure correct output and functionality for non-standard sizes for each model, including activating the "Buy" button when a non-standard size is selected.
- I will take into account all the features of the product linkage module to avoid potential conflicts and maintain stable website operation.

Please send your answers to the questions in private messages — I will be able to more accurately assess the cost and timeline for completing the task. Expand

Good day. I am an individual developer with over 4 years of experience in full-stack development, creating custom OCMOD/PHP modules, and administering ocStore 3.0 systems. I work officially through a sole proprietorship, ensuring direct transparent communication without intermediaries and managers, and I guarantee the careful implementation of a custom size calculator without accumulating junk code in the controllers. I will independently study the logic of your current site come-for.com/ua, write new JS logic for replacing the "Buy" buttons, integrate the calculation form into the new theme, link it with the prices of the donor products of the OAP Pro module, and test the correctness of displaying custom orders in the cart and admin panel.

Hello. Our small team has been designing business solutions, backend engineering, and deeply customizing online stores on ocStore for over 4 years. The task of creating a parametric calculator for custom mattress sizes fully aligns with our profile, and we guarantee the development of a clean, fault-tolerant architecture that will not break when updating products through the OAP Pro communication module. We will set up the activation of the block via a checkbox, hide the basic purchase button, implement AJAX validation of the data entered by the client, and adapt the interface for mobile devices to make it convenient for users to enter centimeters from their smartphones.

Budget: 2500 UAH Deadline: 1 day

Good day. My colleague and I have been specializing in product web development, custom cost calculators, and setting up e-commerce platforms on OpenCart for over 4 years, so the task of implementing a non-standard mattress grid is very clear to us. We will carry out all the work in a secure staging environment (on a test domain) to avoid interfering with the current content of the site: we will develop a Twig template for the product card, integrate size input blocks, configure server-side cost calculation per sq.m/linear m, and ensure the correct transmission of custom product parameters to the order admin panel and the production technical specifications. We will need up to 24 hours to study the code of the installed multi-option Ajax module to form an accurate step-by-step integration plan, the estimated project budget will be $200, the completion time is 3 days, and examples of our technical expertise are presented in the portfolio: drkukharevich.rivne.ua, crave-agency.com.ua, jk-solution.com.ua.

Hello. My partner (designer + full-stack developer) and I have over 4 years of experience in code refactoring, customizing cart logic, and developing for ocStore 2.3/3.0. We are ready to implement a custom size calculator with the OAP Pro module from scratch. We will completely rewrite the logic: the frontend will be implemented using pure JS/AJAX requests with the standard purchase button blocked, and on the backend, we will implement dynamic price recalculation based on related donor products through the event system (Events OpenCart 3) or a neat OCMOD modifier, ensuring secure addition of unique dimensions to the cart (with protection against price tampering in the page code). For the initial technical analysis of the architecture of your new database connections, studying the methods of the OAP module, and displaying custom fields in the admin panel, we will need 1 day. Full development and testing will take 3–4 days at a fixed price of $190–230, and our engineering approach is reflected in our portfolio: hyperfi.tech, espressolab.com.ua, hudi.com.ua.

Hello. I have experience in refining OpenCart/ocStore and related product modules. I will implement a non-standard size block on ocStore 3.0.3.7 with logic similar to the current site: activation via a checkbox, toggle purchase button, cost calculation, and order processing. I will consider the OAP PRO module to ensure that non-standard sizes are correctly linked to individual products. After reviewing the admin panel and the structure of related products, I will be able to accurately assess the timeline and cost.

Hello!

I have extensive experience working with OpenCart.

I suggest we discuss the details in private messages.

Budget: 1001 UAH Deadline: 3 days

Good day! I know OpenCart and have worked with ocStore 3.x.
The task is clear — in the new version, product sizes are implemented as separate products through OAP Pro, and I need to add the logic for a custom size with a checkbox that activates its own "Buy" button and disables the main one.
I looked at come-for.com — I see how it works now.
What I will do:

I will integrate the custom size block compatible with OAP Pro.
The checkbox activates a separate order button for the custom size.
The main "Buy" button is disabled when the checkbox is activated.
The block is displayed only for products where it exists.

Cost: $80–120

Hello! I have experience in development on OpenCart 2-3. I have done a similar task for pre-ordering products where the thickness is selected through an option, I expanded the functionality and made it possible. I can implement the same functionality for you by creating a module with a modifier for the admin panel to add functionality specifically and on the user side as well. There will be 2 modifiers, one for the admin panel and one for the catalog. The cost of the work and the timeline is 50 USD for 4 days including testing.

Budget: 5000 UAH Deadline: 2 days

Good day, I am engaged in the development and support of websites on OpenCart. I am ready to create a similar module for the new site. It would be good to have access to both sites if possible, to create an optimal solution. I am ready to start today.

Budget: 3000 UAH Deadline: 3 days

The main difficulty lies not in displaying non-standard sizes themselves, but in the correct integration with the module where sizes are presented as separate products instead of standard OpenCart options. This is why it is important not just to display an additional block on the product page, but to maintain ease of selection for the customer and ensure proper data transfer to the cart and order.

I will carefully study the current implementation on the live site, analyze the logic of the checkbox, the mechanism for activating non-standard sizes, and the scenario for switching purchase buttons. As a result, the new implementation will closely resemble the familiar interface for clients without degrading the user experience. Compatibility with the template, related products module, and standard cart functionality will also be checked to avoid conflicts during price updates, size selections, or order placements after implementation.

Additionally, I will focus on making the solution as universal as possible. If a specific model has non-standard sizes, the block will be displayed automatically. If this option is not available, the interface will remain unchanged. This will allow for a single solution to be used across the entire catalog without the need for manual adjustments to each product card.

Work plan:

1. Analyze the current implementation of non-standard sizes on the active site.
2. Study the structure of products after transitioning to ocStore 3.0.3.7.
3. Analyze the operation of the related products module and its API.
4. Develop the mechanism for displaying the non-standard size block.
5. Implement the activation logic via checkbox.
6. Configure the switching of the main purchase button and the non-standard size order button.
7. Organize the correct transfer of selected parameters to the cart.
8. Check compatibility with the template and site modifiers.
9. Test product cards with and without non-standard sizes.
10. Final check of the order placement and user scenarios. Expand

Hello, briefly, what needs to be done on the new ocStore 3.0.3.7:
- on the product page, add a checkbox "I want to order in a custom size"
- when the checkbox is checked, show a block with fields Width / Length and live recalculation of the price per 1 m²
- while the block is active, the main button "Buy" dims, and the button "Order" becomes active
- pass the size and calculated price to the cart and the order, so the manager can see the dimensions

I see that on the new site, sizes are presented as separate products through the OAP Pro module, not as options like on the old one. So I will link the block specifically to the main product model, so it appears only where a custom size is provided.

A few questions to avoid guessing:
- The price per 1 m² for each model is different. Where to get it on the new site: a separate product field, an option, or a value from the module?
- Is there a minimum and maximum size and step (for example, only even centimeters)?
- Should the custom size be included in the order as a product with dimensions in the comments or as a separate line?

I am ready to start as we agree. Expand

Budget: 1000 UAH Deadline: 2 days

Hello, I understand the task. I will implement the logic for non-standard sizes for each model in the new version, if it is provided for the product.

Here’s the plan:

1. We will display a non-standard size block on the product card similar to the current website.
2. If the model has such a size, the user will be able to enable it with a checkbox.
3. When selecting a non-standard size, the main Buy button will change according to the logic of the current website.
4. For the new version, we will adapt this to a scheme where sizes are separate products and linked through the OAP Pro module.
5. I will check that the product is correctly added to the cart and that the necessary parameters are transmitted.

Deadline is 1-2 days; I will provide a more precise estimate after access to FTP and verification. Budget is 1k. Expand
