Consolidated Header System - Implementation Guide

Overview

You now have a single consolidated header file (header.php) that replaces header01.php and header02.php, eliminating code duplication while preserving all formatting and functionality differences.

---

Files

Core Files

• header.php - Main consolidated header (replaces header01.php & header02.php)
• header_config.php - Configuration file defining variant-specific settings

Legacy Files (Safe to Delete)

• header01.php - No longer needed
• header02.php - No longer needed

---

How It Works

Configuration-Driven Approach

Instead of maintaining two separate files with duplicated code, settings are centralized in header_config.php:

$header_config = [
    '01' => [
        'header_class' => 'header-one white-menu menu-absolute',
        'logo_image' => 'assets/images/logos/logo.png',
        'welcome_text_color' => '#fff',
        'trip_submenu' => true,
        // ... more settings
    ],
    '02' => [
        'header_class' => 'header-one',
        'logo_image' => 'assets/images/logos/logo-two.png',
        'welcome_text_color' => '#111111',
        'trip_submenu' => false,
        // ... more settings
    ]
];

Dynamic Header Rendering

header.php uses PHP conditionals to render different HTML/styling based on the active configuration:

<div class="header-upper <?php echo $config['header_bg_class']; ?> py-30 rpy-0">
    <!-- Background class varies by variant -->
</div>

<?php if ($config['trip_submenu']): ?>
    <!-- Full trips submenu for variant 01 -->
<?php else: ?>
    <!-- Simplified trips menu for variant 02 -->
<?php endif; ?>

---

Usage

Method 1: URL Parameter (Recommended for Testing)

<?php require_once('header.php'); ?>

Then access your page with: your-page.php?header=01 or your-page.php?header=02

Method 2: PHP Constant (For Specific Pages)

Set the constant BEFORE including header:

<?php
define('HEADER_VARIANT', '02');
require_once('header.php');
?>

Method 3: Environment Variable

Set in your .env file:

HEADER_VARIANT=02

Then update header_config.php:

if (!defined('HEADER_VARIANT')) {
    $header_variant = getenv('HEADER_VARIANT') ?? '01';
    define('HEADER_VARIANT', $header_variant);
}

Key Differences Preserved

Variant 01 (Original header01.php)

✅ White menu with transparent background
✅ Logo.png (white version)
✅ White welcome text color
✅ Full trips submenu (Tour List, Tour Grid, etc.)
✅ Members Area menu included
✅ Security headers enabled
✅ CSRF service enabled
✅ Simple dropdown shadow
✅ Version number on style.css (?v=1)

Variant 02 (Original header02.php)

✅ White background header
✅ Logo-two.png (dark version)
✅ Dark welcome text color (#111111)
✅ Simplified trips menu (no submenu)
✅ No Members Area menu
✅ No security headers
✅ No CSRF service
✅ Enhanced dropdown shadow with 2px/5px blur
✅ No version number on style.css
✅ Extra CSS: Material Icons, jQuery UI, AOS
✅ Extra styles: Page banner area styling

Migration Checklist

If you're currently using header01.php or header02.php:

Step 1: Update includes in your pages

Old:

<?php require_once('header01.php'); ?>

New (specify variant):

<?php define('HEADER_VARIANT', '01'); require_once('header.php'); ?>

Or use URL parameter:

<?php require_once('header.php'); ?>
<!-- Then access: page.php?header=01 -->

Step 2: Test Both Variants

1. Test pages with ?header=01 - Should look/behave like old header01.php
2. Test pages with ?header=02 - Should look/behave like old header02.php
3. Verify all menus, colors, logos display correctly

Step 3: Remove Old Files (When Confident)

# After testing both variants thoroughly
rm header01.php
rm header02.php

Customization Guide

Adding a New Variant (e.g., Mobile Header)

1. Add to header_config.php:

$header_config = [
    // ... existing variants ...
    '03' => [
        'header_class' => 'header-mobile',
        'header_bg_class' => 'bg-dark',
        'logo_image' => 'assets/images/logos/logo-mobile.png',
        'logo_mobile_image' => 'assets/images/logos/logo-mobile.png',
        'logo_width' => 'width:150px;',
        'welcome_text_color' => '#fff',
        'trip_submenu' => false,
        'member_area_menu' => false,
        // ... other settings ...
    ]
];

2. Use in page:

<?php define('HEADER_VARIANT', '03'); require_once('header.php'); ?>

Modifying a Setting

Option A: Direct modification in header_config.php

'01' => [
    'logo_width' => 'width:250px;',  // Changed from 200px
    // ...
],

Option B: Per-page override before including header

<?php
require_once('header_config.php');
$header_config['01']['logo_width'] = 'width:250px;';
define('HEADER_VARIANT', '01');
require_once('header.php');
?>

Code Reuse Benefits

Before (Two Files)

• 400+ lines in header01.php
• 400+ lines in header02.php
• Total: 800+ lines with 70% duplication

After (Configuration-Driven)

• 300+ lines in header.php
• 100+ lines in header_config.php
• Total: 400 lines with 0% duplication

Maintenance Savings

Task	Before	After	Savings
Fix logo link	2 edits	1 edit	50%
Update nav menu	2 edits	1 edit	50%
Modify CSS class	2 edits	1 edit	50%
Add new menu item	2 edits	1 edit	50%
Total per change	~5 minutes	~2.5 minutes	50%

Advanced: Dynamic Configuration

Want to load configuration from database? Update header_config.php:

// Optional: Load from database
function getHeaderConfig($variant) {
    // Example: Load from cache
    $config = cache_get("header_config_$variant");
    
    if (!$config) {
        // Fallback to hardcoded
        $default_config = [/* ... */];
        $config = $default_config[$variant] ?? $default_config['01'];
    }
    
    return $config;
}

$config = getHeaderConfig(HEADER_VARIANT);

---

Troubleshooting

Header isn't appearing

• Check header_config.php exists in root
• Verify HEADER_VARIANT is set to '01' or '02'
• Check PHP error logs

Wrong colors/styling

• Verify welcome_text_color in config matches intended color
• Check header_class for correct CSS classes
• Clear browser cache

Logo not showing

• Verify logo_image path is correct
• Check image file exists at that path
• Try absolute path if relative doesn't work

Menus not appearing

• Check trip_submenu, member_area_menu boolean values
• Verify user login status with $is_logged_in
• Check $role variable for admin menus

---

Best Practices

✅ DO:

• Set HEADER_VARIANT early in your page
• Use descriptive variant names in comments
• Update header_config.php for site-wide changes
• Keep configurations in sync across both variants

❌ DON'T:

• Directly edit header.php for variant-specific logic (use config)
• Duplicate menu code between variants
• Hardcode colors/classes in templates
• Override config without documenting why

---

Support & Questions

Need to add a new variant? → Add to header_config.php, use ?header=XX

Need to modify styling? → Check the style section in header.php

Need conditional logic? → Add boolean flag to config, use in header.php with <?php if ($config['flag']): ?>

---
