Usage

Basic Usage

$path = 'img/uploads'; // The folder to save images.    
$dir = 'dir_name'; // The directory name to save images.  
$surpass = \Surpass::path($path)->dir($dir);

(See also a folder named "exaple" which has some files.)

Upload (in Controller)

$surpass = \Surpass::path('img/uploads')
				->dir('dir_name')
				->ids([
					'input' => 'image_upload',
					'preview' => 'preview_images'
				])
				->maxFiles(5)
				->alert('You can upload up to %d files.')
				->formData([
					'key_1' => 'value_1', 
					'key_2' => 'value_2', 
					'key_3' => 'value_3'
				])
				->preview(['maxHeight' => 120])
				->css([
					'div' => 'div_class', 
					'button' => 'button_class', 
					'preview' => 'preview_class', 
					'loading' => 'loading_class'
				])
				->progress('<img src="http://example.com/img/ajax-loader.gif"><br>Uploading..')
				->callback([
					'upload' => 'alert("Uploading..");', 
					'done' => 'alert("Done.");',
					'failed' => 'alert("Failed..");', 
					'remove' => 'alert("Removed");', 
					'load' => 'alert("Loading..");',
                    'timeout' => 'alert("Timeout..");',
                    'file_type_error' => 'alert("Only image files are allowed");'
				])
				->timeout(3000) // 3 seconds
				->overwrite(false)   // When using overwriting-mode
				->resize(['maxWidth' => '100', 'maxHeight' => '50'], $force_crop = false)   // Client Resizing(See "About resizing")
				->dropZone('drop_zone_id')  // See "Drop Zone"
				->button('Remove');
$surpass->load([1, 2, 3]);    // These are IDs of DB that you saved image(s) in the past.

return view('surpass', [
		
	'surpass' => $surpass
		
]);

*Note: method dir('dir_name') can no longer receive "/" and "." to protect from directory traversal attack.

Upload (in View)

Note1:
Need to load jQuery, jQuery UI and jQuery-File-Upload. (Loading order is important. See the below)
If you can use bower, use bower install blueimp-file-upload --save-dev to install all of the packages easily.

Note2:
Changed tags {{ and }} to {!! and !!} from the previous version.

@section('content')

    <form>
    	<input 
    		id="image_upload" 
    		name="image_upload" 
    		title="Select Image" 
    		data-url="http://example.com/upload" 
    		data-remove-url="http://example.com/remove" 
    		accept="image/*" 
    		type="file" multiple>
    		
        <!-- Preview(s) will be displayed here -->
        {!! $surpass->html('preview') !!}
    </form>
@stop

@section('script')

    <!-- Load required JS libraries. -->
    <script src="bower_components/jquery/dist/jquery.min.js"></script>
    <script src="bower_components/blueimp-file-upload/js/vendor/jquery.ui.widget.js"></script>
    <script src="bower_components/blueimp-load-image/js/load-image.all.min.js"></script>
    <script src="bower_components/blueimp-canvas-to-blob/js/canvas-to-blob.js"></script>
    <script src="bower_components/blueimp-file-upload/js/jquery.iframe-transport.js"></script>
    <script src="bower_components/blueimp-file-upload/js/jquery.fileupload.js"></script>
    <script src="bower_components/blueimp-file-upload/js/jquery.fileupload-process.js"></script>
    <script src="bower_components/blueimp-file-upload/js/jquery.fileupload-image.js"></script>
    <script src="bower_components/blueimp-tmpl/js/tmpl.min.js"></script>

    <!-- JS code (including <script></script> tag) will be displayed here. -->
    {!! $surpass->html('js') !!}
@stop

Upload (Ajax)

*Important: To save images you want, you need to make a specific dir which must be writable in advance.

// To save an image and its data into DB

$surpass = \Surpass::path('img/uploads')->id('input', 'image_upload');
$attributes = array('alt' => 'alt_value', 'title' => 'title_value');  // Optional
$save_dir = $surpass->saveDir();    // The directory you want to save.(Optional)
$surpass->renameFiles(true);    // If you'd like to use the original filename, set false.(Optional)

if($surpass->save($attributes = array())) {

    // You can get the data of saved image like this.

	$load_item = $surpass->loadSaved();
	$id = $load_item->id;
	$dir = $load_item->dir;
	$filename = $load_item->filename;
	$path = $load_item->path;
	$url = $load_item->url;
	$attributes = $load_item->attributes;
	$tag = $load_item->tag;
	
	// You can save attributes also here. (Of course you can do that at other places.)
	
	$id = $load_item->id;
	$surpass->saveAttributes($id, array(
	    'key_1' => 'value_1',
	    'key_2' => 'value_2',
	    'key_3' => 'value_3'
	));
	
}

return $surpass->result();  // This will return json.

*Note 1: If uploading completed, the result data(json) has the following values.
*Note 2: About renameFiles(), See the details

  1. result (true / false)
  2. insertId
  3. path
  4. dir
  5. filename
  6. file_path
  7. extension
  8. width
  9. height
  10. mime_type
  11. saveMode : (overwrite / insert)

Remove (Ajax)

// To remove an image and the data into DB

$surpass = \Surpass::path('img/uploads');

if($surpass->remove()) {
	// Something..
}

return $surpass->result();  // This will return json.

Minimal Way

(in Contoller)

$surpass = \Surpass::path('img/uploads')->dir('dir_name');
$surpass->load([1, 2, 3]);

(in View) See above.

(in Upload Ajax)

$surpass = \Surpass::path('img/uploads');
$dir = $surpass->requestDir();

if($surpass->save()) {
	// Something..
}

return $surpass->result();

(in Remove Ajax)

$surpass = \Surpass::path('img/uploads');

if($surpass->remove()) {
	// Something..
}

return $surpass->result();

Refresh
This method will remove all data and images that don't already exist.

$surpass = \Surpass::path('img/uploads');
$surpass->refresh();

Remove by ID

$surpass = \Surpass::path('img/uploads')->removeById(1);


// or


$surpass = \Surpass::path('img/uploads')->removeById([1, 2, 3]);

Load with validation

$ids = [1, 2, 3];
$surpass->load($ids, $old_flag = true);
// If $old_flag is true, $ids will be replaced with Input::old() value(s) automatically.

Get image file id(s) when submitting

\Surpass::imageFileId('dir_name');
\Surpass::imageFileIds('dir_name');

About Saved IDs

Afeter uploading image(s) with Ajax, the preview(s) have hidden-input-tag(s) named "surpass_ids[]" (and of course the value(s) are ID of DB saved at the time).
So when submitting, you can receive those data as array.

Now You can use imageFileId() and imageFileIds() to get image ID(s) easily.

with Multiple file-inputs
(in Controller)

$surpass = \Surpass::path('img/uploads');
$surpass_x = clone $surpass->dir('xxx')
				->ids([
					'input' => 'input-xxx',
					'preview' => 'preview-xxx'
				]);
$surpass_y = clone $surpass->dir('yyy')
				->ids([
					'input' => 'input-yyy',
					'preview' => 'preview-yyy'
				]);
return view('view', [
	'surpass_x' => $surpass_x,
	'surpass_y' => $surpass_y
]);

(in View)

<input 
	id="input-xxx" 
	name="input-xxx" 
	title="Select Image" 
	data-url="http://example.com/upload" 
	data-remove-url="http://example.com/remove" 
	accept="image/*" 
	type="file" multiple>
{!! $surpass_x->html('preview') !!}  

<input 
	id="input-yyy" 
	name="input-yyy" 
	title="Select Image" 
	data-url="http://example.com/upload" 
	data-remove-url="http://example.com/remove" 
	accept="image/*" 
	type="file" multiple>
{!! $surpass_y->html('preview') !!}  

// JS
{!! $surpass_x->html('js') !!}
{!! $surpass_y->html('js') !!}

Set filename length

\Surpass::filenameLength(10);    // Default: 10

Insert

Note:
This method is to save image(s) and their data directly like seeding.
So, in usual you should use save() method.

$insert_id = \Surpass::path('path')
                ->dir('dir')
                ->insert('file_path', $attributes = []);

Drop Zone

If you'd like to upload images through Drop Zone(using Drag and Drop), add a div-tag like the below.

(in Controller)

$surpass->dropZone('drop_zone_id');


(in View)

<div id="drop_zone_id">Drop images here!</div>

Save Attributes

$id = 1;    // Here means ID of "image_files" table.
$surpass->saveAttributes($id, [
    'key_1' => 'value_1',
    'key_2' => 'value_2',
    'key_3' => 'value_3'
]);

*Note: The old attributes data will be removed.

      }
    

Configuration

After executing vendor:publish, you have a configuration file called surpass.php in /config.
In there, you can change table name that Surpass will use.

Note: For stable DB design, the actual table name in your database will NOT be changed automatically.
So, in order to rename, you need to generate a migration file and to execute it after setting the new table name in the configuration file.
For more details, see Renaming / Dropping Tables or examples/migrations/2016_04_03_063049_rename_image_files_to_thumbnail_files.php.
