# Heat Status Dashboard Integration

## Overview
Integration of heat status cards into the event dashboard for read-only informational display.

## Implementation Date
2025-01-XX

## Components Modified

### 1. Event Dashboard (`admin/event_dashboard.php`)

#### HTML Structure Addition
Added heat cards container in Heat Flow Overview section (line ~488):
```html
<!-- Heat Status Cards (View Only) -->
<div id="heatCardsContainer" class="mt-4">
    <h6 class="text-muted mb-3">
        <i class="fas fa-layer-group me-2"></i>Heat Status Overview
    </h6>
    <div id="heatCardsContent"></div>
</div>
```

#### JavaScript Functions

**loadHeatData()** - Updated to fetch from both APIs:
```javascript
const [flowResponse, cardsResponse] = await Promise.all([
    fetch(`heat_flow_api.php?event_id=${eventId}`),
    fetch(`heat_cards_api.php?event_id=${eventId}`)
]);

const flowData = await flowResponse.json();
const cardsHtml = await cardsResponse.text();

renderHeatData(flowData, cardsHtml);
```

**renderHeatData(flowData, cardsData)** - Accepts both data types:
```javascript
function renderHeatData(flowData, cardsData) {
    // ... existing flow data rendering ...
    
    // Render heat cards (view-only)
    if (cardsData) {
        renderHeatCards(cardsData);
    }
}
```

**renderHeatCards(htmlContent)** - Transforms cards to view-only:
```javascript
function renderHeatCards(htmlContent) {
    const container = document.getElementById('heatCardsContent');
    
    // Parse HTML and remove interactive elements
    const tempDiv = document.createElement('div');
    tempDiv.innerHTML = htmlContent;
    
    // Remove action buttons (footers)
    const footers = tempDiv.querySelectorAll('.card-footer');
    footers.forEach(footer => footer.remove());
    
    // Strip onclick handlers
    const clickableElements = tempDiv.querySelectorAll('[onclick]');
    clickableElements.forEach(el => el.removeAttribute('onclick'));
    
    // Add "View Only" badges
    const cards = tempDiv.querySelectorAll('.card');
    cards.forEach(card => {
        card.style.cursor = 'default';
        // Add badge to header
        const viewOnlyBadge = `<small class="badge bg-secondary ms-2">
            <i class="fas fa-eye me-1"></i>View Only
        </small>`;
        // Append to card header
    });
    
    container.innerHTML = tempDiv.innerHTML;
}
```

## Features

### Display Characteristics
- **Read-Only**: All action buttons removed (Close, Cancel, Reschedule, etc.)
- **Status Visibility**: Shows all heat statuses with color-coded badges
- **Non-Interactive**: onclick handlers stripped, cursor set to default
- **Visual Indicator**: "View Only" badges added to each card header

### Status Badge Colors (from heat_cards_api.php)
- **Pending**: Gray (`bg-secondary`)
- **Active**: Yellow (`bg-warning`)
- **Finished**: Blue (`bg-info`)
- **Cancelled**: Red (`bg-danger`)
- **Rescheduled**: Orange (`bg-warning text-dark`)

## Integration Flow

```
Event Dashboard Load
    ↓
loadHeatData() called
    ↓
Promise.all([
    heat_flow_api.php,    // Flow chains & stats
    heat_cards_api.php    // Status cards
])
    ↓
renderHeatData(flowData, cardsHtml)
    ↓
renderHeatCards(cardsHtml)
    ↓
    → Remove footers
    → Strip onclick attributes
    → Add "View Only" badges
    ↓
Display in heatCardsContent div
```

## User Interface

### Location
**Event Dashboard → Heat Flow Overview Panel → Bottom Section**

### Layout

- Each card shows:
  - Heat number/name
