▶ Expenses Type Controller API Documentation

■ 1. Controller Overview

• → Purpose: Comprehensive expense type/category management system with hierarchical organization
• → Module: Financial Management → Expense Types (انواع المصروفات)
• → File: controllers/expensesTypeController.php (620 lines)
• → Primary Database Table: expensestype
• → Dependencies:
• → Extensive DAO/DTO pattern with MySQL implementations

• → CURL Post Support: Enhanced support for external systems calling the controller
• → JSON Response Integration: All operations support JSON responses for API compatibility

// CURL POST detection throughout controller

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

    // JSON response for external systems

    $data = array('status' => 1, 'message' => 'تمت العمليه بنجاح', 'message_en' => 'Success');

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

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

• 🆕 Daily Entry Integration

• → Accounting Integration: include_once("dailyentryfun.php") (Line 9)
• → Chart of Accounts: Automatic integration with accounting tree via addTreeElement() and editTreeElement()
• → Account Tree Management: Each expense type creates corresponding account in chart of accounts

}

// Dependency check before deletion

$childCount = ExpenseType::where('parent', $expensestypeid)->count();

$expenseCount = Expense::where('expensestypeid', $expensestypeid)->count();

">if (">$childCount > 0 || $expenseCount > 0) {
    throw new BusinessException('Cannot delete expense type - has dependencies');

■ 11. Daily Entry System Integration

• Database Tables for Daily Entry

▪ dailyentry - Journal Entry Header

CREATE TABLE dailyentry (
    dailyentryid INT PRIMARY KEY AUTO_INCREMENT,
    dailyentrydate DATE NOT NULL,
    dailyentrycomment TEXT,
    dailyentrytotalvalue DECIMAL(15,2) NOT NULL DEFAULT 0,
    conditions TINYINT NOT NULL DEFAULT 0,  -- 0=active, 1=deleted

    userid INT NOT NULL,
    creationDate DATETIME NOT NULL,
    operationId INT NOT NULL DEFAULT 0,
    operationDetailLink VARCHAR(500),
    costCenterID INT NOT NULL DEFAULT 0
);

▪ dailyentrydebtor - Debit Entries

CREATE TABLE dailyentrydebtor (
    dailyentrydebtoreid INT PRIMARY KEY AUTO_INCREMENT,
    dailyentryid INT NOT NULL,  -- Foreign key to dailyentry

    accountstreeid INT NOT NULL, -- Foreign key to accountstree

    dailyentrydebtorevalue DECIMAL(15,2) NOT NULL,
    dailyentrydebtorecomment TEXT,
    conditions TINYINT NOT NULL DEFAULT 0,
    costCenterID INT NOT NULL DEFAULT 0
);

▪ dailyentrycreditor - Credit Entries

CREATE TABLE dailyentrycreditor (
    dailyentrycreditorid INT PRIMARY KEY AUTO_INCREMENT,
    dailyentryid INT NOT NULL,  -- Foreign key to dailyentry

    accountstreeid INT NOT NULL, -- Foreign key to accountstree

    dailyentrycreditorvalue DECIMAL(15,2) NOT NULL,
    dailyentrycreditorcomment TEXT,
    conditions TINYINT NOT NULL DEFAULT 0,
    costCenterID INT NOT NULL DEFAULT 0
);

• Daily Entry Integration Functions

▪ Core Daily Entry Functions (from dailyentryfun.php)

/
◆ Creates journal entries with debtor and creditor records

◆ This is the core function that maintains double-entry bookkeeping


 */
function insertEntery($dailyEntryObj, $dailyEntryDebtorArray, $dailyEntryCreditorArray, 
                     $stopEntryTransaction = 0, $operationId = 0, $operationDetailLink = '') {

    // Creates dailyentry record

    // Creates multiple dailyentrydebtor records

    // Creates multiple dailyentrycreditor records

    // Calls affectAccount() for each account affected

}

/
◆ Creates or updates account tree elements for expense types

 */
function addTreeElement(">$name, $parent, ">$itemtype, $itemfrom, $itemtype2, 
                       ">$notes = '', $theOrder = 0, ">$theValue = 0, $reportid = 0) {

    // itemtype: 0=expenses, 1=liabilities, 2=revenue, 3=assets, 4=capital

    // itemfrom: 0=from program, 1=from tree only

    // itemtype2: 0=parent node, 1=end element (used in entries)

}

/
◆ Updates account balances based on transaction type

 */
">function affectAccount($CreditorOrDebtorObj, $type) {
    // type: 'debtor' or 'creditor'

    // Updates accountstree.theValue based on account type and transaction

}

• Expense Type Creation with Daily Entry Integration

When an expense type is created, the system:

1. Creates Expense Type Record

INSERT INTO expensestype (...) VALUES (...)

1. Creates Account Tree Entry (via addTreeElement())

INSERT INTO accountstree (
    name, parent, itemtype, itemfrom, itemtype2, 
    accountNature, notes, theValue, userid, sysdate, reportid
) VALUES (?, ?, 0, 0, 1, ?, ?, 0, ?, ?, ?)

1. Updates Expense Type with Tree ID

UPDATE expensestype SET treeId = ? WHERE expensestypeid = ?

• Expense Transaction Workflow

When an actual expense is recorded against an expense type:

1. Create Expense Record

INSERT INTO expenses (expensestypeid, expensesValue, ...) VALUES (...)

1. Create Journal Entry (via insertEntery())

-- Create journal header

INSERT INTO dailyentry (
    dailyentrydate, dailyentrycomment, dailyentrytotalvalue, 
    conditions, userid, creationDate, operationId
) VALUES (?, ?, ?, 0, ?, ?, ?)

-- Create debit entry (expense account)

INSERT INTO dailyentrydebtor (
    dailyentryid, accountstreeid, dailyentrydebtorevalue, 
    dailyentrydebtorecomment, conditions
) VALUES (?, ?, ?, ?, 0)

-- Create credit entry (cash/bank account)

INSERT INTO dailyentrycreditor (
    dailyentryid, accountstreeid, dailyentrycreditorvalue, 
    dailyentrycreditorcomment, conditions
) VALUES (?, ?, ?, ?, 0)

1. Update Account Balances (via affectAccount())

-- Update expense account balance (increase with debit)

UPDATE accountstree SET theValue = theValue + ? WHERE id = ?

-- Update cash/bank account balance (decrease with credit)

UPDATE accountstree SET theValue = theValue - ? WHERE id = ?

• Account Type Behavior in Daily Entry System

// From dailyentryfun.php - Account behavior rules

">function whatToDo(">$accountType, ">$numSign, $type) {
    // $accountType: 0=expenses, 1=liabilities, 2=revenue, 3=assets, 4=capital

    // $numSign: +/- amount

    // $type: 'debtor' or 'creditor'

    
    switch($accountType) {
        case 0: // مصروفات (Expenses)

        case 3: // أصول (Assets)

            // Debit increases, Credit decreases

            ">if ($type == 'debtor') return $numSign;      // +amount

            ">if ($type == 'creditor') return -$numSign;   // -amount

            break;
            
        case 1: // خصوم (Liabilities)

        case 2: // إيرادات (Revenue) 

        case 4: // رأس المال (Capital)

            // Debit decreases, Credit increases

            ">if ($type == 'debtor') return -$numSign;     // -amount

            ">if ($type == 'creditor') return $numSign;    // +amount

            break;
    }
}

• Plugin System Integration

The expense type system integrates with the plugin system (from affectplugins.php):

// Plugin mapping for expense types

$pluginMapArr = array(
    'expenses' => 411,  // Main expenses account tree ID

    'save' => 40,       // Cash accounts

    'bank' => 38        // Bank accounts

);

// When expense is recorded, plugin system routes to appropriate handlers

">function affectPlugin(">$whatIsIt, ">$val, ">$id, $operation, ">$elementName, $comment, 
                     $controllerName, $costCenterID, $accountstreeid, $whichSideisIt, 
                     $dailyEntry, $AllDailyEntryDebtor, $AllDailyEntryCreditor) {
    // Routes expense transactions to proper account handling

    // Updates cash/bank balances

    // Creates audit trail

}

• API Integration with Daily Entry

For API implementation, expense type operations must maintain daily entry integration:

// API Endpoint: POST /api/v1/expense-types/{id}/expenses

">public function createExpense(Request $request, $expenseTypeId) {
    DB::transaction(">function() ">use ($request, $expenseTypeId) {
        // 1. Create expense record

        $expense = Expense::create([
            'expensestypeid' => $expenseTypeId,

            'expensesValue' => $request->amount,

            'expensesDetails' => $request->description,

            'saveid' => $request->save_id,

            'userid' => Auth::id()

        ]);
        
        // 2. Get expense type and account tree info

        $expenseType = ExpenseType::with('accountTree')->find($expenseTypeId);

        ">$save = Save::find($request->save_id);
        
        // 3. Prepare daily entry data

        $dailyEntry = [
            'dailyentrydate' => date('Y-m-d'),

            'dailyentrycomment' => "مصروف: {$expenseType->expensestypename}",

            'dailyentrytotalvalue' => $request->amount,

            'operationId' => $expense->expensesid,

            'operationDetailLink' => 'expenses'

        ];
        
        $debtorArray = [
            [
                'accountstreeid' => $expenseType->treeId,  // Expense account

                'value' => $request->amount,

                'comment' => $request->description

            ]
        ];
        
        $creditorArray = [
            [
                'accountstreeid' => $save->accountTreeId,  // Cash/Bank account

                'value' => $request->amount,

                'comment' => "دفع مصروف: {$expenseType->expensestypename}"

            ]
        ];
        
        // 4. Create journal entry (calls insertEntery function)

        insertEntery($dailyEntry, $debtorArray, $creditorArray, 0, 
                    $expense->expensesid, 'expenses');

    });
}

■ 10. Testing Strategy

• Unit Tests

• → Expense type CRUD operations
• → Hierarchical tree building
• → Dependency validation
• → Accounting integration
• → User permission handling

• Integration Tests

• → API endpoint functionality
• → Chart of accounts synchronization
• → Tree structure validation
• → Bulk operations
• → JSON response formatting

• Performance Tests

• → Large hierarchy handling
• → Concurrent tree modifications
• → Search functionality
• → Recursive queries optimization

• Example Test Cases
