## At a glance

- **Vendor**: etechflow (https://packagento.com/etechflow.md)
- **Latest version**: 1.2.1 — released 2026-06-22
- **Pricing**: Free
- **Package type**: Magento 2 module
- **Status**: active, accepting new buyers

## Installation

Packagento is licence-gated, so even free packages need a licence on a project before Composer can resolve them.

1. **Sign in or create an account** at https://packagento.com/customer/account/.

2. **Add the package to your account.** Open https://packagento.com/etechflow/module-variant-links and complete the free checkout. A licence is minted automatically.

3. **Create or pick a project, then activate the licence on it.**
   - Projects represent the Magento installs you deploy to. Manage them at https://packagento.com/projects/.
   - Activate the new licence on the project you'll deploy this package to. Activation is what generates the Composer credentials scoped to that project.

4. **Add the project credentials to your Magento codebase.**

   Grab the project's public + private key from https://packagento.com/projects/ (open the project, then its Credentials tab), and add them to `auth.json`:

   ```json
   {
     "http-basic": {
       "packagento.com": {
         "username": "ppk_live_...",
         "password": "psk_live_..."
       }
     }
   }
   ```

   Add the Packagento Composer repository to `composer.json`:

   ```json
   {
     "repositories": [
       { "type": "composer", "url": "https://packagento.com" }
     ]
   }
   ```

5. **Install and apply.**

   ```bash
   composer require etechflow/module-variant-links:*
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   ```

## What it does

Dynamic 'View Other Options/Finishes/Sizes' PDP buttons driven by per-product link attributes; replaces hardcoded in-description buttons and strips the old ones at render time.

## README


Dynamic **"View Other Options / Finishes / Sizes"** product-detail-page (PDP) buttons for
Magento 2 (Hyvä), driven by per-product link attributes — replacing hardcoded
in-description buttons and stripping the old ones at render time.

### What it does

Many catalogues link product variants ("see this lock in another finish/size") with
anchors hand-baked into the product description HTML. That's unmaintainable: the links
rot, the markup is inconsistent, and the domain is hardwired. This module replaces that
pattern with three editable product attributes and renders clean, on-brand buttons on the
PDP.

- Adds three per-product attributes — `variant_options_url`, `variant_finishes_url`,
  `variant_sizes_url` — each holding a **relative** URL (path + filter query), e.g.
  `/euro-cylinders?manufacturer=2081`. The frontend prepends the store base URL, so the
  domain is always correct. A blank value hides that button.
- Editable in the admin product form (group **Variant Links**) and importable via the
  standard product CSV.
- **Legacy stripping:** removes old hand-coded "View Other …" anchors from the
  description at render time, so the migration is reversible — the source description is
  untouched.
- **Dynamic mode** (optional, off by default): instead of stored URLs, build the target
  link at render time from a category + filter attribute, via `DynamicLinkBuilder` /
  `FilterUrlBuilder`.
- Bulk import + a legacy-button migration CLI for one-shot catalogue conversion.

### Install

```bash
composer require etechflow/module-variant-links
bin/magento module:enable ETechFlow_VariantLinks
bin/magento setup:upgrade
bin/magento setup:di:compile        # production
```

The `setup:upgrade` runs the data patch that creates the three attributes.

### Configuration

**Stores → Configuration → ETechFlow → Variant Links** (`etechflow_variantlinks/*`):

| Setting | Default | Purpose |
|---|---|---|
| `buttons/enabled` | `variant_finishes,variant_sizes` | Which buttons render |
| `buttons/options_label` | `View Other Options` | Label for the options button |
| `buttons/finishes_label` | `View Other Finishes` | Label for the finishes button |
| `buttons/sizes_label` | `View Other Sizes` | Label for the sizes button |
| `dynamic/enabled` | `0` | Build links at render time instead of from stored URLs |
| `dynamic/default_size_attribute` | — | Attribute used for dynamic size links |
| `dynamic/size_attribute_map` | — | Per-category size-attribute overrides |

### Rendering

The buttons are produced by `ViewModel\VariantLinks`. Wire it into the theme's
`product-info` template (or equivalent) to output the buttons; `LegacyButtonStripper`
cleans the old anchors out of the description in the same pass.

> Note: `FilterUrlBuilder` is intentionally kept as a separate seam so a future SEO
> layered-navigation module can share readable filter-URL generation.

### CLI

```bash
bin/magento etechflow:variantlinks:import        # bulk import variant link attributes
bin/magento etechflow:variantlinks:migrate-legacy # convert hardcoded in-description buttons
```

### Requirements

## Quality

Latest release (1.2.1) fails the Packagento QA pipeline. Verdicts below are per-cell (Magento line × PHP version) for the matrixed tools, and run-once for the static / security tiers.


### Compatibility

Each Magento line is installed on its supported PHP versions, then the module is built (DI compile + static-content deploy). Cells show passed / failed / untested; staircase gaps render as `–`.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | Pass | Pass | – | – |
| 2.4.8 | – | Pass | Pass | – |
| 2.4.9 | – | – | not tested | Pass |


### Code Quality

Advisory checks against the module's source. Never affect the Compatibility verdict — a phpcs finding can't make a module incompatible.

#### Static Analysis

Coding standards (phpcs), mess detection (phpmd), copy-pasted code (cpd), PHP cross-version compatibility, composer.json validity. Each runs once for the whole module.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| PHPCS | Fail | 197 | 3 errors, 194 warnings (ruleset: Magento2) — 109 auto-fixable with phpcbf |
| PHPMD | Warning | 34 | 34 rule violations (NPathComplexity:8, UnusedFormalParameter:7, EmptyCatchBlock:7, CyclomaticComplexity:6, UnusedLocalVariable:4) |
| Cpd | Pass | 0 |  |
| Composer validate | Info | 3 | valid; 3 advisory notes (composer validate --strict) |

#### PHPStan

Type-checks the module against a real Magento install. Re-runs per Magento + PHP version because resolvable symbols differ between releases.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | 21 | 21 | – | – |
| 2.4.8 | – | 21 | 21 | – |
| 2.4.9 | – | – | 21 | 21 |


### Tests

Unit and integration suites run per Magento + PHP cell. Test failures speak to the module's behaviour, not its compatibility with a line, so they're reported here separately.

#### Unit Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |

#### Integration Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |


### Security

Dependency-advisory audit (composer audit) plus a source malware scan. A malware detection fails the version outright.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| Composer audit | Pass | 0 |  |
| Malware scan | Pass | 0 |  |

## Licence and pricing

Free. A licence is still minted on checkout and bound to your project for Composer access — no payment step.

Refundable within 14 days of first purchase via https://packagento.com/account/refunds/.

## Install via Claude Code or any MCP client

The Packagento MCP server can run the licence + project + Composer steps above in one tool call:

```
purchase_and_install_packages(
  composer_names=["etechflow/module-variant-links"],
  project_id="proj_xxx"
)
```

This handles cart, checkout, licence minting, project activation, and writes auth.json credentials. Connect a client with `claude mcp add packagento https://mcp.packagento.com`. Full setup at https://packagento.com/docs/mcp-setup.
