- Events fired before, during, and after upload(s).
- Allows integration of external asset management systems, S3, CDNs, etc.
- Provides file icons.
- Ajax uploads.
- Progress bars.
- Uses jQuery File Upload
- ...and more.
Installation is similar to a standard bundle. http://symfony.com/doc/current/cookbook/bundles/installation.html
- Add bundle to composer.json: https://packagist.org/packages/symfonycontrib/filefield-bundle
- Add bundle to AppKernel.php:
- jQuery is required but not provided by this bundle.
- Include JS files (order is important):
- 'bundles/filefield/js/vendor/jquery.ui.widget.js' (only required if jQuery UI is not installed)
- Include CSS file
By default the bundle loads a form template to theme the default fields. If you want to customize filefield themeing, you can disable loading of the default template by setting
# app/config/parameters.yml filefield.load_form_template: false
Simple single file upload backed by an array:
// Only URI is required. $data = [ 'name' => 'examplefile.txt', 'mime_type' => 'text/plain', 'size' => 50, 'uri' => '/uploads/examplefile.txt', ]; ... // These are the only two required options but there are many more. $builder->add('file', 'filefield', [ 'upload_dir' => '/absolute/system/path/to/upload/dir/web/uploads', 'uri' => '/uploads/', ]);
Simple multi-file upload backed by an array of File objects.
$data = [ new File('/path/to/file'), new File('/path/to/file'), ]; ... $builder->add('files', 'filefield', [ 'upload_dir' => '/absolute/system/path/to/upload/dir/web/uploads', 'uri' => '/uploads/', 'multiple' => true, 'limit' => 2, 'allow_add' => true, 'allow_delete' => true, ]);
At its core, FileFieldBundle only takes care of uploading the file from the browser to a server. This means that most of the display portion of the file in the form is offloaded to some other form that is used as a sub-form very much like the core collection form field.
However, FileFieldBundle does provide a simple display form type that is used by default if no other form type is provided. This form type simply displays the filename(linked to the file), a file icon representing the mime type, and the file size.
