__construct(string $path, string $originalName, string $mimeType = null, int $error = null, bool $test = false)

Accepts the information of the uploaded file as provided by the PHP global $_FILES.

The file object is only created when the uploaded file is valid (i.e. when the isValid() method returns true). Otherwise the only methods that could be called on an UploadedFile instance are:

• getClientOriginalName,
• getClientMimeType,
• isValid,
• getError.

Calling any other method on an non-valid instance will cause an unpredictable result.

Parameters

string	$path	The path to the file
string	$originalName	The original file name of the uploaded file
string	$mimeType	The type of the file as provided by PHP; null defaults to application/octet-stream
int	$error	The error constant of the upload (one of PHP's UPLOAD_ERR_XXX constants); null defaults to UPLOAD_ERR_OK
bool	$test	Whether the test mode is active Local files are used in test mode hence the code should not enforce HTTP uploads

Exceptions

FileException	If file_uploads is disabled
FileNotFoundException	If the file does not exist

string|null guessExtension()

Returns the extension based on the mime type.

If the mime type is unknown, returns null.

This method uses the mime type as guessed by getMimeType() to guess the file extension.

Return Value

string|null

The guessed extension or null if it cannot be guessed

getMimeType()

string|null getMimeType()

Returns the mime type of the file.

The mime type is guessed using a MimeTypeGuesser instance, which uses finfo(), mime_content_type() and the system binary "file" (in this order), depending on which of those are available.

Return Value

string|null

The guessed mime type (e.g. "application/pdf")

File move(string $directory, string $name = null)

Moves the file to a new location.

Parameters

string	$directory	The destination folder
string	$name	The new file name

Return Value

File	A File object representing the new file

Exceptions

FileException

if, for any reason, the file could not have been moved

protected getTargetFile($directory, $name = null)

	$name

protected string getName(string $name)

Returns locale independent base name of the given path.

Parameters

string

$name

The new file name

Return Value

string

containing

string|null getClientOriginalName()

Returns the original file name.

It is extracted from the request from which the file has been uploaded. Then it should not be considered as a safe value.

Return Value

string|null

The original name

string getClientOriginalExtension()

Returns the original file extension.

It is extracted from the original file name that was uploaded. Then it should not be considered as a safe value.

Return Value

string

The extension

string|null getClientMimeType()

Returns the file mime type.

The client mime type is extracted from the request from which the file was uploaded, so it should not be considered as a safe value.

For a trusted mime type, use getMimeType() instead (which guesses the mime type based on the file content).

Return Value

string|null

The mime type

getMimeType()

string|null guessClientExtension()

Returns the extension based on the client mime type.

If the mime type is unknown, returns null.

This method uses the mime type as guessed by getClientMimeType() to guess the file extension. As such, the extension returned by this method cannot be trusted.

For a trusted extension, use guessExtension() instead (which guesses the extension based on the guessed mime type for the file).

Return Value

string|null

The guessed extension or null if it cannot be guessed

int|null getClientSize() ^deprecated

^deprecated

since Symfony 4.1, use getSize() instead.

Returns the file size.

It is extracted from the request from which the file has been uploaded. Then it should not be considered as a safe value.

Return Value

int|null

The file sizes

int getError()

Returns the upload error.

If the upload was successful, the constant UPLOAD_ERR_OK is returned. Otherwise one of the other UPLOAD_ERR_XXX constants is returned.

Return Value
