| $checkExtensionByMimeType |
|
whether to check file type (extension) with mime-type. If extension produced by
file mime-type check differs from uploaded file extension, the file will be considered as invalid. |
|
| $extensions |
|
a list of file name extensions that are allowed to be uploaded.
This can be either an array or a string consisting of file extension names
separated by space or comma (e.g. "gif, jpg").
Extension names are case-insensitive. Defaults to null, meaning all file name
extensions are allowed. |
|
| $maxFiles |
|
the maximum file count the given attribute can hold.
Defaults to 1, meaning single file upload. By defining a higher number,
multiple uploads become possible. Setting it to 0 means there is no limit on
the number of files that can be uploaded simultaneously.
> Note: The maximum number of files allowed to be uploaded simultaneously is
also limited with PHP directive max_file_uploads, which defaults to 20. |
|
| $maxSize |
|
the maximum number of bytes required for the uploaded file.
Defaults to null, meaning no limit.
Note, the size limit is also affected by upload_max_filesize and post_max_size INI setting
and the 'MAX_FILE_SIZE' hidden field value. See FileValidator::getSizeLimit for details. |
|
| $message |
|
the error message used when a file is not uploaded correctly. |
|
| $mimeTypes |
|
a list of file MIME types that are allowed to be uploaded.
This can be either an array or a string consisting of file MIME types
separated by space or comma (e.g. "text/plain, image/png").
The mask with the special character * can be used to match groups of mime types.
For example image/* will pass all mime types, that begin with image/ (e.g. image/jpeg, image/png).
Mime type names are case-insensitive. Defaults to null, meaning all MIME types are allowed. |
|
| $minSize |
|
the minimum number of bytes required for the uploaded file.
Defaults to null, meaning no limit. |
