Interfaces

FileInterface
Interface for a file object. This can be any kind of file object, e.g. a processed file (which is not a FAL file), or a file reference object, which is a decorator around a "File" object, but of course without any additional file on the file system.

Properties

$deleted  : bool
If set to true, this file is regarded as being deleted.
$name  : string
The file name of this file
$properties  : array<non-empty-string, mixed>
Various file properties
$storage  : ResourceStorage|null
The storage this file is located in

Methods

delete()  : bool
Deletes this file from its storage. This also means that this object becomes useless.
exists()  : bool
Checks if this file exists. This should normally always return TRUE; it might only return FALSE when this object has been created from an index record without checking for.
getCombinedIdentifier()  : string
Returns a combined identifier of this file, i.e. the storage UID and the folder identifier separated by a colon ":".
getContents()  : string
Get the contents of this file
getCreationTime()  : int
Returns the creation time of the file as Unix timestamp
getExtension()  : string
Get the extension of this file in a lower-case variant
getFileType()  : FileType
Returns the fileType of this file basically there are only five main "file types" "audio" "image" "software" "text" "video" "other" see FileType enum
getForLocalProcessing()  : non-empty-string
Returns a path to a local version of this file to process it locally (e.g. with some system tool).
getHashedIdentifier()  : non-empty-string
getMimeType()  : non-empty-string
Get the MIME type of this file
getModificationTime()  : int
Returns the date (as UNIX timestamp) the file was last modified.
getName()  : string
getNameWithoutExtension()  : string
Returns the basename (the name without extension) of this file.
getParentFolder()  : Folder
getProperties()  : array<non-empty-string, mixed>
Returns the properties of this object.
getProperty()  : mixed
Returns a property value
getPublicUrl()  : string|null
Returns a publicly accessible URL for this file
getSha1()  : non-empty-string
Returns the Sha1 of this file
getSize()  : int<0, max>
MUST return the size of the file as unsigned int i.e. 0-max.
getStorage()  : ResourceStorage
getType()  : int
Returns the fileType of this file basically there are only five main "file types" "audio" "image" "software" "text" "video" "other" see FileType enum
getUid()  : int
Returns the uid of this file
hasProperty()  : bool
Returns true if the given property key exists for this file.
isDeleted()  : bool
Returns TRUE if this file has been deleted
isImage()  : bool
Useful to find out if this file can be previewed or resized as image.
isMediaFile()  : bool
Useful to find out if this file has a file extension based on any of the registered media extensions
isTextFile()  : bool
Useful to find out if this file can be edited.
isType()  : bool
setContents()  : $this
Replace the current file contents with the given string
setDeleted()  : void
Marks this file as deleted. This should only be used inside the File Abstraction Layer, as it is a low-level API method.
setStorage()  : $this
Sets the storage this file is located in. This is only meant for \TYPO3\CMS\Core\Resource-internal usage; don't use it to move files.
updateProperties()  : mixed
Updates properties of this object.

Properties

$deleted

If set to true, this file is regarded as being deleted.

protected bool $deleted = false

$name

The file name of this file

protected string $name = ''

$properties

Various file properties

protected array<non-empty-string, mixed> $properties = []

Note that all properties, which only the persisted (indexed) files have are stored in this overall properties array only. The only properties which really exist as object properties of the file object are the storage, the identifier, the fileName and the indexing status.

Methods

delete()

Deletes this file from its storage. This also means that this object becomes useless.

public delete() : bool
Return values
bool

exists()

Checks if this file exists. This should normally always return TRUE; it might only return FALSE when this object has been created from an index record without checking for.

public exists() : bool
Return values
bool —

TRUE if this file physically exists

getCombinedIdentifier()

Returns a combined identifier of this file, i.e. the storage UID and the folder identifier separated by a colon ":".

public getCombinedIdentifier() : string
Return values
string —

Combined storage and file identifier, e.g. StorageUID:path/and/fileName.png

getContents()

getForLocalProcessing()

Returns a path to a local version of this file to process it locally (e.g. with some system tool).

public getForLocalProcessing([bool $writable = true ]) : non-empty-string

If the file is normally located on a remote storages, this creates a local copy. If the file is already on the local system, this only makes a new copy if $writable is set to TRUE.

Parameters
$writable : bool = true

Set this to FALSE if you only want to do read operations on the file.
