▶ Client Controller API Documentation

■ 1. Controller Overview

• → Purpose: Comprehensive customer/client management system with complex relationships
• → Module: Customer Management / CRM
• → File: controllers/clientController.php (1,805 lines) - Updated Version
• → Primary Database Table: client
• → Dependencies:
• → Extensive DAO/DTO pattern with MySQL implementations
• → RedBean ORM for additional tables
• → Smarty templating engine
• → PHPExcel for bulk imports
• → Image upload functionality
• → Daily entry (accounting integration)
• → Tree management (accounts tree)

■ 2. New Version Updates (v2024)

• 🆕 API Mode Support

The controller now includes basic API functionality:

// API Mode Check - Lines 6-29

">if (isset(">$_GET['api_mode']) && $_GET['api_mode'] == '1') {

    header('Content-Type: application/json; charset=utf-8');

    
    ">$action = isset(">$_GET['action']) ? $_GET['action'] : 'test';

    
    ">if ($action == 'test') {

        echo json_encode(array(
            'status' => 'success',

            'message' => 'API working via existing controller',

            'timestamp' => date('Y-m-d H:i:s'),

            'user_id' => isset($_SESSION['userid']) ? $_SESSION['userid'] : null

        ));
        exit;
    }
    
    ">if ($action == 'list') {

        $clients = R::getAll('SELECT clientid, clientname, clientmobile FROM client WHERE conditions = 0 LIMIT 10');

        echo json_encode(array(
            'status' => 'success',

            'data' => $clients

        ));
        exit;
    }
}

• 🆕 Enhanced CURL/External Integration

• → New File Integration: initiateStaticSessionCommingWithCurl.php (Line 33)
• → CURL Post Support: Enhanced support for external systems calling the controller
• → Session Management: Improved session handling for external integrations

// 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' => $httpStatusCodes[200]);

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

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

• 🆕 New Operation: addSimpleReturn

• → Purpose: Special operation for linking clients with suppliers
• → AJAX Support: Added to $ajaxDoArr array
• → Functionality:
• → Creates client if doesn't exist
• → Links existing client to supplier
• → Removes previous supplier links

">elseif ($do == "addSimpleReturn") { //special for link with supplier

    try {
        $id = add();
        ">if ($id == -1) {
            //there is client with same name => get its id

            ">$checkName = $clientDAO->queryByClientname($_POST['txtName']);

            ">$id = ">$clientId = $checkName[0]->clientid;
            $supplierId = (int) $_POST["linkedSupplierId"];

            //link

            //remove any link to same suppplier

            $clientExt->removeAnyClientLinkForASupplier($supplierId);

            $checkName[0]->linkedSupplierId = $supplierId;
            ">$clientDAO->update($checkName[0]);
        }
        ">echo $id; //it is client id

    } ">catch (Exception $e) {
        header("location:?do=error");
    }
}

• 🆕 Enhanced JSON Response Integration

Multiple operations now support both web and API responses:

• → savedata operation
• → deleteFinaly operation
• → delete operation
• → updatedata operation

3. Authentication: Integrate JWT with existing session system
4. Data Migration: Ensure data integrity during transition
5. Testing: Comprehensive testing with existing data
6. Documentation: API documentation and client examples

• Critical Validations

// Client creation validation

$rules = [
    'clientname' => 'required|string|max:256|unique:client,clientname',

    'clientphone' => 'nullable|string|max:20|regex:/^[0-9+\-\s()]+$/',

    'clientmobile' => 'nullable|string|max:20|regex:/^[0-9+\-\s()]+$/',

    'clientdebt' => 'numeric|min:-999999.99|max:999999.99',

    'debtLimit' => 'numeric|min:0|max:999999.99',

    'clientareaid' => 'required|exists:clientarea,id',

    'clientcode' => 'nullable|string|max:255|unique:client,clientcode',

    'txtemail' => 'nullable|email|max:256',

    'taxnumber' => 'nullable|string|max:255'

];

// Business rule validations

">if (">$clientdebt < 0 && !$allowNegativeDebt) {
    throw new ValidationException(&#039;Negative debt not allowed&#039;);

}

">if (">$debtLimit > 0 && ">$clientdebt > $debtLimit) {
    throw new ValidationException(&#039;Initial debt exceeds credit limit&#039;);

}

• Database Optimizations

-- Add essential indexes

CREATE INDEX idx_client_name ON client(clientname);
CREATE INDEX idx_client_phone ON client(clientphone);
CREATE INDEX idx_client_mobile ON client(clientmobile); 
CREATE INDEX idx_client_area ON client(clientareaid);
CREATE INDEX idx_client_conditions ON client(conditions);
CREATE INDEX idx_client_debt ON client(clientdebt);
CREATE INDEX idx_client_adddate ON client(addDate);
CREATE INDEX idx_client_code ON client(clientcode);

-- Debt history indexes

CREATE INDEX idx_debtchange_client ON clientdebtchange(clientid);
CREATE INDEX idx_debtchange_date ON clientdebtchange(clientdebtchangedate);
CREATE INDEX idx_debtchange_type ON clientdebtchange(clientdebtchangetype);

-- Search optimization indexes

CREATE INDEX idx_client_search ON client(clientname, clientphone, clientmobile, clientcode);
