FileNameFilter
class FileNameFilter (View source)
Filter certain characters from file name, for nicer (more SEO-friendly) URLs as well as better filesystem compatibility.
Caution: Does not take care of full filename sanitization in regards to directory traversal etc., please use PHP's built-in basename() for this purpose.
For file name filtering see {@link FileNameFilter}.
The default sanitizer is quite conservative regarding non-ASCII characters, in order to achieve maximum filesystem compatibility. In case your filesystem supports a wider character set, or is case sensitive, you might want to relax these rules via overriding {@link FileNameFilter_DefaultFilter::$default_replacements}.
To leave uploaded filenames as they are (being aware of filesystem restrictions),
add the following code to your YAML config:
SilverStripe\Assets\FileNameFilter:
default_use_transliterator: false
default_replacements:
See {@link URLSegmentFilter} for a more generic implementation.
Traits
Provides extensions to this object to integrate it with standard config API methods.
A class that can be instantiated or replaced via DI

Methods
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Gets the uninherited value for the given config option
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Depending on the applied replacement rules, this method might result in an empty string. In this case, {@link getDefaultName()} will be used to return a randomly generated file name, while retaining its extension.
Take care not to add replacements which might invalidate the file structure, e.g. removing dots will remove file extension information.

static Injectable
create(array ...$args)
An implementation of the factory method, allows you to create an instance of a class
This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.
This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create('SiteTree'); $list = SiteTree::get();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
string
filter(string $name)
Depending on the applied replacement rules, this method might result in an empty string. In this case, {@link getDefaultName()} will be used to return a randomly generated file name, while retaining its extension.
setReplacements(array $replacements)
Take care not to add replacements which might invalidate the file structure, e.g. removing dots will remove file extension information.
