▶ Product Controller API Documentation

■ 1. Controller Overview

• → Purpose: Comprehensive product/inventory management system with advanced features
• → Module: Inventory Management / Product Catalog
• → File: controllers/productController.php (5,533 lines) - Updated Version
• → Primary Database Table: product
• → Dependencies:
• → Complex DAO/DTO pattern with 20+ related models
• → RedBean ORM for additional operations
• → PHPExcel for bulk imports/exports
• → Image processing for product photos
• → Barcode generation and management
• → Store management and inventory tracking
• → Accounting integration (daily entries)
• → Manufacturing/production features

■ 2. New Version Updates (v2024)

• 🆕 Enhanced CURL/External Integration

• → New File Integration: initiateStaticSessionCommingWithCurl.php (Line 11)
• → Improved Session Handling: Better support for external system integration
• → JSON Response Support: Added throughout various operations for API compatibility

• 🆕 Enhanced AJAX Operations

Updated AJAX operations array:

$ajaxDoArr = array("addOneSimpleReturn", "addsizeColorToProductAjax", "editAjax", "productsAndProUnitsToExcel");

• 🆕 External System Integration

Multiple operations now support both web and API responses:

// CURL POST detection throughout controller

">if (isset($_POST['curlpost']) && $_POST['curlpost'] == 1) {

    // JSON response for external systems

    $data = array('status' => 'success', 'status_code' => 200, 'message' => $response);

    ">echo json_encode($data);
} else {
    // Standard web response

    header("location:?do=sucess");
}

• 🆕 Improved Excel Integration

• → New Operation: productsAndProUnitsToExcel for advanced reporting
• → Enhanced PHPExcel Usage: Better integration with Excel processing
• → Export Capabilities: Improved product data export functionality

■ 3. Business Logic Analysis

• Core Operations

1. CREATE: Add products with categories, pricing, units, and inventory
2. READ: Display products with advanced filtering and search
3. UPDATE: Edit product information with inventory adjustments
4. DELETE: Soft delete with inventory reconciliation
5. BULK IMPORT: Excel-based product imports with validation
6. BARCODE MANAGEMENT: Generate and print barcodes/labels
7. INVENTORY TRACKING: Store-wise quantity management
8. PRICE MANAGEMENT: Multiple price tiers and calculations
9. MANUFACTURING: Production recipes and raw materials
10. OPTICS: Specialized handling for optical products with size/color

• → Optic Products: Special handling for glasses/lenses
• → Online Integration: E-commerce synchronization
• → Accounting Integration: Automatic inventory value calculations

• Data Validation & Business Rules

• → Product Name: Required, can have duplicates in different categories
• → Category Assignment: Must belong to valid product category
• → Pricing Rules: Buy price ≤ sell prices, configurable markups
• → Inventory Limits: Minimum stock alerts and maximum limits
• → Barcode Uniqueness: System-wide unique barcode enforcement
• → Unit Relationships: Proper conversion factors between units
• → Manufacturing Logic: Raw material availability for production
• → Store Distribution: Products can be available in specific stores only

▪ Business Logic Integration:

1. Category Handling: Uses special optic categories (getProductCatParentOptic())
2. Variant Management: Automatically enables size/color variants for optical products
3. Inventory Tracking: Creates separate inventory for each variant
4. Barcode Generation: Individual barcodes for each variant
5. Store Movement: Records initial inventory addition
6. Accounting Integration: Links to daily entry system for inventory valuation

▪ API Endpoint Mapping:

• API Endpoint to SQL Mapping

▪ GET /api/v1/products (List Products)

Implementation SQL:

-- Base query with category information

SELECT product.*, productcat.productCatName,
       SUM(sd.productquantity) as totalQuantity,
       COUNT(DISTINCT sd.storeid) as storeCount
FROM product
JOIN productcat ON product.productCatId = productcat.productCatId

LIMIT ? OFFSET ?

-- With filters:

-- Category filter: AND product.productCatId = ?

-- Search: AND (product.productName LIKE "%?%" OR product.parcode LIKE "%?%")

-- Price range: AND product.productSellUnitPrice BETWEEN ? AND ?

-- Store: AND EXISTS(SELECT 1 FROM storedetail WHERE productid = product.productId AND storeid = ?)

-- Low stock: HAVING totalQuantity < product.limitamount

▪ POST /api/v1/products (Create Product)

Implementation SQL (Transaction):

BEGIN TRANSACTION;

-- Insert main product

VALUES (?, ?, ?, ?, ...);
SET @product_id = LAST_INSERT_ID();

-- Insert units

INSERT INTO productunit (productid, unitid, unitsellprice, unitbuyprice, unitquantity, isMainUnit, ...)

-- Generate barcode

INSERT INTO availableparcode (value) VALUES (?);

COMMIT;

▪ PUT /api/v1/products/{id} (Update Product)

Implementation SQL:

BEGIN TRANSACTION;

-- Update main product

UPDATE product SET productName = ?, productBuyPrice = ?, ... WHERE productId = ?;

-- Handle units (replace all)

DELETE FROM productunit WHERE productid = ?;
INSERT INTO productunit (productid, unitid, ...) VALUES (?, ?, ...);

-- Update store quantities

UPDATE storedetail SET productquantity = ?, ... WHERE productid = ? AND storeid = ?;

-- Handle variants

DELETE FROM sizecolor WHERE productid = ?;
INSERT INTO sizecolor (productid, sizename, ...) VALUES (?, ?, ...);

COMMIT;

▪ GET /api/v1/products/{id} (Get Single Product)

Implementation SQL:

-- Main product with category

SELECT p.*, pc.productCatName FROM product p
JOIN productcat pc ON p.productCatId = pc.productCatId
WHERE p.productId = ? AND p.conditions = 0;

-- Product units

SELECT pu.*, u.unitName FROM productunit pu

-- Store inventory

SELECT sd.*, s.storeName FROM storedetail sd

4. Inventory Management: Implement real-time inventory tracking
5. Manufacturing: Support production recipes and raw materials
6. Testing: Comprehensive testing with existing data

• Critical Validations

    'productName' => 'required|string|max:256',

    'productCatId' => 'required|exists:productcat,productCatId',

    'productBuyPrice' => 'required|numeric|min:0',

    'productSellUnitPrice' => 'required|numeric|gte:productBuyPrice',

    'parcode' => 'nullable|string|max:256|unique:product,parcode|unique:sizecolor,parcode',

    'limitamount' => 'integer|min:0',

    'type' => 'in:0,1',

    'isService' => 'boolean',

    'isOptic' => 'in:0,1,2',

    'hasSizeAndColor' => 'boolean'
