# Adding HTML Support to Listing Descriptions

This guide provides step-by-step instructions to add HTML support for listing descriptions, allowing hosts to use paragraphs, bullet points, and other HTML formatting.

---

## Files to Modify

You will need to modify **3 files** in total:

1. **View File (Display)**: `resources/views/livewire/listing-details.blade.php`
2. **Form File (Input)**: `resources/views/livewire/host/listing-manager.blade.php`
3. **Controller (Validation)**: `app/Livewire/Host/ListingManager.php`

---

## Step 1: Update Display View (Show HTML Content)

**File**: `resources/views/livewire/listing-details.blade.php`

**Line to Find**: Line 209

**Current Code**:
```blade
<p class="text-gray-700 dark:text-gray-300">{{ $listing->description }}</p>
```

**Replace With**:
```blade
<div class="text-gray-700 dark:text-gray-300 prose prose-sm max-w-none
     prose-headings:text-gray-900 dark:prose-headings:text-gray-100
     prose-p:text-gray-700 dark:prose-p:text-gray-300
     prose-ul:text-gray-700 dark:prose-ul:text-gray-300
     prose-ol:text-gray-700 dark:prose-ol:text-gray-300
     prose-li:text-gray-700 dark:prose-li:text-gray-300
     prose-strong:text-gray-900 dark:prose-strong:text-white">
    {!! nl2br(e($listing->description)) !!}
</div>
```

**What this does**:
- Converts the simple `<p>` tag to a styled `<div>` with Tailwind's prose classes
- `{!! nl2br(e($listing->description)) !!}` converts line breaks to `<br>` tags while escaping HTML for security
- The prose classes provide beautiful typography styling for text content

---

## Step 2: Update Form Input (WYSIWYG Editor)

**File**: `resources/views/livewire/host/listing-manager.blade.php`

**Line to Find**: Lines 89-93

**Current Code**:
```blade
<div>
    <label class="block text-sm font-medium text-gray-700 dark:text-gray-300 mb-2">Description</label>
    <textarea wire:model="description" rows="4" required class="w-full rounded-md border-gray-300 dark:border-gray-600 dark:bg-gray-700 dark:text-white shadow-sm focus:border-blue-500 focus:ring-blue-500"></textarea>
    @error('description') <span class="text-red-500 text-xs">{{ $message }}</span> @enderror
</div>
```

**Replace With**:
```blade
<div>
    <label class="block text-sm font-medium text-gray-700 dark:text-gray-300 mb-2">
        Description
    </label>
    <p class="text-xs text-gray-600 dark:text-gray-400 mb-2">
        💡 Formatting tips: Use line breaks for paragraphs. You can use basic formatting.
    </p>
    <textarea
        wire:model="description"
        rows="8"
        required
        class="w-full rounded-md border-gray-300 dark:border-gray-600 dark:bg-gray-700 dark:text-white shadow-sm focus:border-blue-500 focus:ring-blue-500 font-mono text-sm"
        placeholder="Describe your listing...

Example:
This is a beautiful property perfect for families.

Features include:
- Spacious living area
- Modern amenities
- Great location

Book now and enjoy your stay!"></textarea>

    <div class="mt-2 p-3 bg-blue-50 dark:bg-blue-900/20 rounded-lg border border-blue-200 dark:border-blue-800">
        <p class="text-xs text-blue-800 dark:text-blue-200 font-medium mb-1">
            ℹ️ Preview will show formatted text with proper line breaks
        </p>
    </div>

    @error('description') <span class="text-red-500 text-xs">{{ $message }}</span> @enderror
</div>
```

**What this does**:
- Increases textarea rows from 4 to 8 for better editing
- Adds helpful placeholder text showing formatting examples
- Adds a monospace font for better text editing
- Adds a blue info box explaining the formatting
- Provides visual hints to users about how to format their descriptions

---

## Step 3: Update Validation (Allow More Text)

**File**: `app/Livewire/Host/ListingManager.php`

**Line to Find**: Line 206

**Current Code**:
```php
'description' => 'required|string',
```

**Replace With**:
```php
'description' => 'required|string|max:5000',
```

**What this does**:
- Adds a maximum character limit of 5000 characters
- Prevents database overflow while allowing detailed descriptions
- You can adjust this number (e.g., 3000, 10000) based on your needs

---

## Optional Enhancement: Rich Text Editor (TinyMCE)

If you want a full WYSIWYG (What You See Is What You Get) editor, follow these additional steps:

### Step A: Add TinyMCE to Layout

**File**: `resources/views/layouts/app.blade.php`

**Add before closing `</head>` tag**:
```html
<script src="https://cdn.tiny.cloud/1/no-api-key/tinymce/6/tinymce.min.js" referrerpolicy="origin"></script>
```

### Step B: Initialize TinyMCE in Form

**File**: `resources/views/livewire/host/listing-manager.blade.php`

**Replace the textarea section with**:
```blade
<div wire:ignore>
    <label class="block text-sm font-medium text-gray-700 dark:text-gray-300 mb-2">
        Description
    </label>
    <textarea
        id="description-editor"
        wire:model="description"
        rows="8"
        required
        class="w-full"></textarea>
</div>

<script>
document.addEventListener('livewire:init', () => {
    tinymce.init({
        selector: '#description-editor',
        height: 400,
        menubar: false,
        plugins: 'lists link code',
        toolbar: 'undo redo | formatselect | bold italic | bullist numlist | link | code',
        setup: function(editor) {
            editor.on('change keyup', function() {
                tinymce.activeEditor.save();
                @this.set('description', editor.getContent());
            });
        }
    });
});
</script>

@error('description') <span class="text-red-500 text-xs">{{ $message }}</span> @enderror
```

### Step C: Update Display to Render HTML

**File**: `resources/views/livewire/listing-details.blade.php`

**Change line 209 to**:
```blade
<div class="text-gray-700 dark:text-gray-300 prose prose-sm max-w-none">
    {!! $listing->description !!}
</div>
```

⚠️ **Security Warning**: Only use `{!! !!}` if you trust your hosts or implement HTML sanitization!
