</html>

4. Configure Storage (Optional)

If using server upload mode, link storage:

php artisan storage:link

⚙️ Configuration

After publishing configuration, edit config/image-cropper.php:

return [
    /*
    |--------------------------------------------------------------------------
    | Default Storage Disk
    |--------------------------------------------------------------------------
    |
    | This option controls the default storage disk that will be used to store
    | uploaded images. You may set this to any of the disks defined in your
    | config/filesystems.php configuration file.
    */
    'disk' => env('IMAGE_CROPPER_DISK', 'public'),

    /*
    |--------------------------------------------------------------------------
    | Default Folder
    |--------------------------------------------------------------------------
    |
    | This is the default folder where uploaded images will be stored.
    */
    'default_folder' => env('IMAGE_CROPPER_FOLDER', 'uploads/images'),

    /*
    |--------------------------------------------------------------------------
    | Default Image Format
    |--------------------------------------------------------------------------
    |
    | This option controls the default format for saved images.
    | Supported: 'webp', 'jpg', 'png', 'original'
    */
    'default_format' => env('IMAGE_CROPPER_FORMAT', 'webp'),

    /*
    |--------------------------------------------------------------------------
    | Default Image Quality
    |--------------------------------------------------------------------------
    |
    | This option controls the default quality for saved images (0-100).
    */
    'default_quality' => env('IMAGE_CROPPER_QUALITY', 90),

    /*
    |--------------------------------------------------------------------------
    | Client-Side Only Mode
    |--------------------------------------------------------------------------
    |
    | When enabled, images are only cropped client-side and sent as base64
    | without server upload. When disabled, images are uploaded to server.
    */
    'client_side_only' => env('IMAGE_CROPPER_CLIENT_SIDE_ONLY', true),

    /*
    |--------------------------------------------------------------------------
    | Auto-Process Form Inputs
    |--------------------------------------------------------------------------
    |
    | When enabled, automatically processes all form inputs with 
    | class "image-cropper" and transforms them into cropping interfaces.
    */
    'auto_process_forms' => env('IMAGE_CROPPER_AUTO_PROCESS', true),

    /*
    |--------------------------------------------------------------------------
    | Default Aspect Ratios
    |--------------------------------------------------------------------------
    |
    | This option defines the default aspect ratios available for selection.
    | Use 'Free' for free cropping (no fixed ratio).
    */
    'default_ratios' => [
        'Free' => null,
        'Square 1:1' => 1,
        'Landscape 16:9' => 16/9,
        'Portrait 9:16' => 9/16,
        '4:3' => 4/3,
        '3:2' => 3/2,
    ],

    /*
    |--------------------------------------------------------------------------
    | Upload Route
    |--------------------------------------------------------------------------
    |
    | This option defines the route for image uploads (when not in client-side mode).
    */
    'upload_route' => env('IMAGE_CROPPER_UPLOAD_ROUTE', '/image-upload'),
];

🚀 Usage Examples

Method 1: Auto-Transform (Easiest)

Simply add image-cropper class to any file input:

<form method="POST" action="/submit">
    @csrf
    
    <!-- This input will be automatically transformed -->
    <div class="mb-3">
        <label for="profile_image" class="form-label">Profile Image</label>
        <input type="file" 
               name="profile_image" 
               class="form-control image-cropper"
               required>
    </div>
    
    <button type="submit" class="btn btn-primary">Submit</button>
</form>

Method 2: Blade Component (Recommended)

Use the included Blade component for more control:

<x-image-cropper 
    name="profile_image"
    label="Upload Profile Picture"
    help="Select and crop your profile picture (Max: 5MB)"
    required
    class="mt-3"
/>

<!-- With custom ratios -->
<x-image-cropper 
    name="banner_image"
    label="Banner Image"
    :ratios="[
        'Banner 3:1' => 3/1,
        'Square' => 1,
        'Portrait' => 2/3,
    ]"
    :radio="true"
    :crop="true"
/>

            <!-- Method 2: Auto-transformed input -->
            <div class="mb-3">
                <label class="form-label">Cover Image</label>
                <input type="file"
                       name="cover_image"
                       class="form-control image-cropper"
                       required>
                <div class="form-text">Select and crop your cover image</div>
            </div>

            <button type="submit" class="btn btn-primary">Submit</button>

    <script src="{{ asset('vendor/image-cropper/js/auto-transform.js') }}"></script>
</body>
</html>

Method 3: Server-Side Upload Controller

If not using client-side mode, create a controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Sharifuddin\ImageCropper\Facades\ImageCropper;

class ImageController extends Controller
{
    public function upload(Request $request)
    {
        $request->validate([
            'image' => 'required|string',
        ]);

        try {
            // Save image with custom settings
            $path = ImageCropper::saveImage(
                base64: $request->input('image'),
                folder: 'profiles',
                quality: 85,
                format: 'webp',
                filename: 'user-' . auth()->id()
            );

            // Get public URL
            $url = ImageCropper::getPublicUrl($path);

            return response()->json([
                'success' => true,
                'path' => $path,
                'url' => $url,
                'message' => 'Image uploaded successfully'
            ]);
            
        } catch (\Exception $e) {
            return response()->json([
                'success' => false,
                'message' => $e->getMessage()
            ], 400);
        }
    }
}

Method 4: Handling Form Submission (Client-Side Mode)

When using client-side mode, handle the base64 image in your controller:

public function store(Request $request)
{
    $request->validate([
        'profile_image' => 'required|string',
    ]);

    $base64Image = $request->input('profile_image');
    
    // Decode and save manually
    if (preg_match('/^data:image\/(\w+);base64,/', $base64Image, $type)) {
        $data = substr($base64Image, strpos($base64Image, ',') + 1);
        $data = base64_decode($data);
        
        // Generate filename
        $filename = 'profile_' . auth()->id() . '_' . time() . '.webp';
        $path = 'profiles/' . $filename;
        
        // Save to storage
        Storage::disk('public')->put($path, $data);
        
        // Save to database
        auth()->user()->update([
            'profile_image' => $path
        ]);
        
        return redirect()->back()->with('success', 'Profile image updated!');
    }
    
    return redirect()->back()->with('error', 'Invalid image format');
}

📁 Advanced Features

1. Multiple File Types Support

// Save video (supports up to 10GB)
$videoPath = ImageCropper::saveVideo($base64Video, 'videos', 'my-video', 10);

// Save audio
$audioPath = ImageCropper::saveAudio($base64Audio, 'audio', 'podcast');

// Save any file
$filePath = ImageCropper::saveFile($base64File, 'documents', 'application/pdf', 'document');

2. Image Processing Functions

// Get image dimensions
$dimensions = ImageCropper::getImageDimensions($base64Image);
// Returns: ['width' => 800, 'height' => 600, 'ratio' => 1.333]

// Check if valid image
$isValid = ImageCropper::isValidImage($base64Image); // true/false

// Generate unique filename
$filename = ImageCropper::generateFilename('jpg', 'profile');

// Check if file exists
$exists = ImageCropper::fileExists('uploads/image.jpg');

// Delete file
$deleted = ImageCropper::deleteFile('uploads/old-image.jpg');

3. Global JavaScript Configuration

You can customize the behavior globally:

// Add this before the auto-transform.js script
window.imageCropperGlobalConfig = {
    client_side_only: true, // or false for server uploads
    upload_url: '/api/image-upload', // required if client_side_only is false
    ratios: {
        'Free': null,
        'Square': 1,
        'Wide 2:1': 2/1,
        'Instagram Post': 1.91/1,
        'Instagram Story': 9/16
    },
    auto_process_forms: true,
    max_file_size: 5, // MB
};

4. Event Handling

Listen to image upload events:

document.addEventListener('DOMContentLoaded', function() {
    document.addEventListener('imageUploaded', function(e) {
        const { path, url } = e.detail;
        console.log('Image uploaded:', path);
        console.log('Image URL:', url);
        
        // Update UI or show notification
        alert('Image uploaded successfully!');
    });
});

🎨 Custom Styling

You can customize the appearance by overriding the CSS:

/* Override in your app.css */
.global-image-cropper-container {
    border: 2px dashed #4a5568;
    border-radius: 10px;
    background: #f7fafc;
}

.cropped-image-preview .card {
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
    color: white;
}

.ratio-option {
    background: #edf2f7;
    border-radius: 8px;
    transition: all 0.3s ease;
}

.ratio-option:hover {
    background: #cbd5e0;
    transform: translateY(-2px);
}

🔧 Troubleshooting

Common Issues & Solutions:

Modal doesn't open
- Check if Bootstrap 5 and Cropper.js are loaded
- Verify console for JavaScript errors
Image not saving
- Check storage permissions: chmod -R 775 storage
- Ensure storage is linked: php artisan storage:link
- Check disk configuration in config/filesystems.php
Base64 too large for form submission
- Increase post_max_size and upload_max_filesize in php.ini
- Consider using server upload mode for large images
Cropper.js not found
- Ensure Cropper.js CDN is included before auto-transform.js
- Check network tab for failed resource loading
