## Installation

### Via Composer

Add the repository to your Magento project's `composer.json`:

```json
{
    "repositories": {
        "module-order-items-custom": {
            "type": "vcs",
            "url": "https://code.shopkeeper.dev/McQueen/module-order-items-custom.git"
        }
    }
}
```

Then install:

```bash
composer require shopkeeper/module-order-items-custom:dev-main
php bin/magento module:enable Shopkeeper_OrderItemsCustom
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:flush
```

### Manual Installation

```bash
# From your Magento root directory
mkdir -p app/code/Shopkeeper/OrderItemsCustom
# Upload all module files to app/code/Shopkeeper/OrderItemsCustom/

php bin/magento module:enable Shopkeeper_OrderItemsCustom
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:flush
```

## Usage

After installation, the changes are automatically applied to all order views in the admin panel.

### Viewing Orders

1. Go to **Sales > Orders**
2. Open any order
3. Scroll to the **Items Ordered** section

You'll see:
- No tax columns
- A new "Cost" column showing product costs
- Clickable product names and SKUs that open the product edit page

### Analyzing Profitability

With both Price and Cost visible side-by-side, you can quickly:
- Calculate profit margins
- Identify high-margin products
- Review cost accuracy for ordered items

## Requirements

- Magento 2.4.x (or 2.3.x with compatible framework versions)
- PHP 7.4, 8.1, 8.2, or 8.3
- Product cost attribute configured in Magento

## Technical Details

### Plugin Architecture

The module uses Magento's plugin system (interceptors) to modify:

1. **Magento\Sales\Block\Adminhtml\Order\View\Items**
   - Plugin: `ItemsColumns`
   - Removes tax columns
   - Adds cost column definition

2. **Magento\Sales\Block\Adminhtml\Order\View\Items\Renderer\DefaultRenderer**
   - Plugin: `DefaultRenderer`
   - Renders cost column with formatted values
   - Adds clickable links to product names and SKUs
   - Handles missing products gracefully

### Module Structure

```
Shopkeeper/OrderItemsCustom/
├── Plugin/
│   └── Order/
│       └── View/
│           ├── ItemsColumns.php
│           └── Items/
│               └── Renderer/
│                   └── DefaultRenderer.php
├── etc/
│   ├── di.xml
│   └── module.xml
├── composer.json
└── registration.php
```

### Cost Attribute

The module expects a product attribute with code `cost`. To configure:

1. Go to **Stores > Attributes > Product**
2. Ensure "cost" attribute exists
3. Set costs for your products via:
   - Bulk import
   - Individual product edit pages
   - API updates

## Troubleshooting

### Cost shows "N/A" for all products

**Possible causes:**
1. Cost attribute not configured
2. Cost values not set for products
3. Permissions issue accessing product data

**Solutions:**
```bash
# Verify cost attribute exists
php bin/magento catalog:product:attributes:list | grep cost

# Reindex if needed
php bin/magento indexer:reindex

# Check product has cost value
# Go to Catalog > Products > Edit Product > Advanced Pricing
```

### Links not working

1. **Clear cache:**
   ```bash
   php bin/magento cache:flush
   ```

2. **Check admin permissions:**
   - Ensure your admin role has access to edit products

3. **Verify module is enabled:**
   ```bash
   php bin/magento module:status Shopkeeper_OrderItemsCustom
   ```

### Tax columns still showing

1. **Clear generated code:**
   ```bash
   rm -rf generated/code/*
   php bin/magento setup:di:compile
   ```

2. **Clear cache:**
   ```bash
   php bin/magento cache:flush
   ```

## Customization

### Removing Different Columns

To remove other columns, edit `Plugin/Order/View/ItemsColumns.php`:

```php
// Add to the $excludedColumns array
$excludedColumns = [
    'tax-amount',
    'tax-percent',
    'discount-amount',  // Add this line to remove discount column
];
```

### Adding Different Columns

To add more columns, modify the same file:

```php
$columns = $result->setData([
    // ... existing columns ...
    'your-column-name' => [
        'label' => __('Your Column Label'),
    ],
]);
```

Then implement rendering in `Plugin/Order/View/Items/Renderer/DefaultRenderer.php`.
