# Video Help System Setup Guide

## Overview
This guide explains how to implement video tutorials throughout your ITRPOS system. The system allows administrators to manage video links for different pages and provides an easy way for users to access helpful tutorials.

## 🚀 Quick Start

### 1. Database Setup
Run the SQL file to create the video help table:
```sql
-- Execute the create_video_help_table.sql file
-- This creates the video_help table with sample data
```

### 2. Access Video Help Management
Navigate to: `video_help_management.php`
- Add, edit, and manage video links for different pages
- Set page names, titles, video URLs, and descriptions
- Enable/disable videos as needed

### 3. Add Video Help to Pages
Follow the template in `video_help_template.php` to add video help to any page.

## 📋 Implementation Steps

### Step 1: Include Video Help Functions
Add this line at the top of your page (after other includes):
```php
include 'functions/video_help.php';
```

### Step 2: Add Video Help Button
Choose one of these options:

**Option A: Full Button with Text**
```php
<?= display_video_help_button('page_name', $conn, '<i class="fa fa-play-circle"></i> Watch Video', 'btn-outline-primary') ?>
```

**Option B: Icon Only Button**
```php
<?= display_video_help_icon('page_name', $conn, 'fa-play-circle', 'btn-outline-info') ?>
```

### Step 3: Add Video Help Modal
Add this at the end of your page (before closing body tag):
```php
<?= display_video_help_modal() ?>
```

## 🎯 Page Names Reference
