Upload
class Upload extends Controller (View source)
Manages uploads via HTML forms processed by PHP, uploads to Silverstripe's default upload directory, and either creates a new or uses an existing File-object for syncing with the database.
Validation
By default, a user can upload files without extension limitations, which can be a security risk if the webserver is not properly secured. Use setAllowedExtensions() to limit this list, and ensure the "assets/" directory does not execute scripts (see http://doc.silverstripe.org/secure-development#filesystem). File::$allowed_extensions provides a good start for a list of "safe" extensions.
Traits

__call(string $method, array $arguments)
Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located
You can add extra methods to a class using Extensions}, {@link Object::createMethod() or Object::addWrapperMethod()
protected
defineMethods()
Adds any methods from Extension instances attached to this object.
All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

defineExtensionMethods()
Adds any methods from Extension instances attached to this object.
All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().
static bool
add_extension(string $classOrExtension, string $extension = null)
Add an extension to a specific class.
The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.
As an alternative, extensions can be added to a specific class directly in the Object::$extensions array. See SiteTree::$extensions for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through singleton()).
static
remove_extension(string $extension)
Remove an extension from a class.
Note: This will not remove extensions from parent classes, and must be called directly on the class assigned the extension.
Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any Object instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through singleton() to avoid side-effects from stale extension information.

No description
static array|null
get_extra_config_sources(string $class = null)
Get extra config sources for this class
static bool
has_extension(string $classOrExtension, string $requiredExtension = null, bool $strict = false)
Return TRUE if a class has a specified extension.
This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))
array
invokeWithExtensions(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)
Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array
array
extend(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)
Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed
Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.
The extension methods are defined during __construct()} in {@link defineMethods().
Extension|null
getExtensionInstance(string $extension)
Get an extension instance attached to this object by name.
bool
hasExtension(string $extension)
Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.
Caution: Don't use singleton(
Extension[]
getExtensionInstances()
Get all extension instances for this specific object instance.
See get_extensions() to get all applied extension classes for this class (not the instance).
This method also provides lazy-population of the extension_instances property.
static Injectable
create(mixed ...$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::class); $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).

$this
setField(string $field, mixed $value)
Set a field on this object. This should be overloaded in child classes.

customise(array|ViewableData $data)
Merge some arbitrary data in with this object. This method returns a ViewableData_Customised instance with references to both this and the new custom data.
Note that any fields you specify will take precedence over the fields on this object.
bool
exists()

object|DBField
cachedCall(string $field, array $arguments = [], string $identifier = null)
A simple wrapper around ViewableData::obj() that automatically caches the result so it can be used again without re-running the method.
bool
hasValue(string $field, array $arguments = [], bool $cache = true)
Checks if a given method/field has a valid value. If the result is an object, this will return the result of the exists method, otherwise will check if the result is not just an empty paragraph tag.

Get the string value of a field on this object that has been suitable escaped to be inserted directly into a template.
array
getXMLValues(array $fields)
Get an array of XML-escaped values by field name

This is useful so you can use a single record inside a <% control %> block in a template - and then use to access individual fields on this object.
array
getViewerTemplates(string $suffix = '')
Find appropriate templates for SSViewer to use to render this object
ViewableData
Me()
When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.

ThemeDir()
deprecated
deprecated
Return the directory if the current active theme (relative to the site root).
This method is useful for things such as accessing theme images from your template without hardcoding the theme
page - e.g. 
.
This method should only be used when a theme is currently active. However, it will fall over to the current project directory.
string
CSSClasses(string $stopAtClass = self::class)
Get part of the current classes ancestry to be used as a CSS class.
This method returns an escaped string of CSS classes representing the current classes ancestry until it hits a stop point - e.g. "Page DataObject ViewableData".
ViewableData_Debugger
Debug()
Return debug information about this object that can be rendered into a template
HTTPResponse|RequestHandler|string|array
handleRequest(HTTPRequest $request)
Executes this controller, and return an HTTPResponse object with the result.
This method defers to RequestHandler->handleRequest() to determine which action should be executed
Note: You should rarely need to overload handleRequest() - this kind of change is only really appropriate for things like nested controllers - ModelAsController} and {@link RootURLController are two examples here. If you want to make more orthodox functionality, it's better to overload init()} or {@link index().
Important: If you are going to overload handleRequest, make sure that you start the method with $this->beforeHandleRequest() and end the method with $this->afterHandleRequest()

storeTempFile(array $tmpFile, string $filename, AssetContainer|AssetStore $container)
Assign this temporary file into the given destination
protected string|false
getValidFilename(array $tmpFile, string $folderPath = null)
Given a temporary file and upload path, validate the file and determine the value of the 'Filename' tuple that should be used to store this asset.
protected string
resolveExistingFile(string $filename)
Given a file and filename, ensure that file renaming / replacing rules are satisfied
If replacing, this method may replace $this->file with an existing record to overwrite. If renaming, a new value for $filename may be returned
setReplaceFile(bool $replace)

validate(array $tmpFile)
Container for all validation on the file (e.g. size and extension restrictions).
Is NOT connected to the {Validator} classes, please have a look at {FileField->validate()} for an example implementation of external validation.
AssetContainer
getFile()
Get file-object, either generated from {load()}, or manually set.
setFile(AssetContainer $file)
Set a file-object (similiar to {loadIntoFile()})
clearErrors()
Clear out all errors (mostly set by {loadUploaded()}) including the validator's errors
bool
isError()
Determines wether previous operations caused an error.
array
getErrors()
Return all errors that occurred while processing so far (mostly set by {loadUploaded()})
string
getDefaultVisibility()
Get default visibility for uploaded files. {AssetStore} One of the values of AssetStore::VISIBILITY_* constants
$this
setDefaultVisibility(string $visibility)
Assign default visibility for uploaded files. {AssetStore} One of the values of AssetStore::VISIBILITY_* constants
