Class: filetypes_util - X-Ref
Utility class for handling with file types in the forms.This class is supposed to serve as a helper class for {@link MoodleQuickForm_filetypes}
and {@link admin_setting_filetypes} classes.
The file types can be specified in a syntax compatible with what filepicker
and filemanager support via the "accepted_types" option: a list of extensions
(e.g. ".doc"), mimetypes ("image/png") or groups ("audio").
| normalize_file_types($types) X-Ref |
| Converts the argument into an array (list) of file types. The list can be separated by whitespace, end of lines, commas, colons and semicolons. Empty values are not returned. Values are converted to lowercase. Duplicates are removed. Glob evaluation is not supported. The return value can be used as the accepted_types option for the filepicker. param: string|array $types List of file extensions, groups or mimetypes return: array of strings |
| looks_like_mimetype($type) X-Ref |
| Does the given file type looks like a valid MIME type? This does not check of the MIME type is actually registered here/known. param: string $type return: bool |
| is_filetype_group($type) X-Ref |
| Is the given string a known filetype group? param: string $type return: bool|object false or the group info |
| get_groups_info() X-Ref |
| Provides a list of all known file type groups and their properties. return: array |
| get_group_description($group) X-Ref |
| Return a human readable name of the filetype group. param: string $group return: string |
| describe_file_types($types) X-Ref |
| Describe the list of file types for human user. Given the list of file types, return a list of human readable descriptive names of relevant groups, types or file formats. param: string|array $types return: object |
| data_for_browser($onlytypes=null, $allowall=true, $current=null) X-Ref |
| Prepares data for the filetypes-browser.mustache param: string|array $onlytypes Allow selection from these file types only; for example 'web_image'. param: bool $allowall Allow to select 'All file types'. Does not apply with onlytypes are set. param: string|array $current Current values that should be selected. return: array |
| expand($types, $keepgroups=false, $keepmimetypes=false) X-Ref |
| Expands the file types into the list of file extensions. The groups and mimetypes are expanded into the list of their associated file extensions. Depending on the $keepgroups and $keepmimetypes, the groups and mimetypes themselves are either kept in the list or removed. param: string|array $types param: bool $keepgroups Keep the group item in the list after expansion param: bool $keepmimetypes Keep the mimetype item in the list after expansion return: array list of extensions and eventually groups and types |
| is_listed($types, $list) X-Ref |
| Should the file type be considered as a part of the given list. If multiple types are provided, all of them must be part of the list. Empty type is part of any list. Any type is part of an empty list. param: string|array $types File type or list of types to be checked. param: string|array $list An array or string listing the types to check against. return: boolean |
| is_whitelisted() X-Ref |
| get_not_listed($types, $list) X-Ref |
| Returns all types that are not part of the given list. This is similar check to the {@see self::is_listed()} but this one actually returns the extra types. param: string|array $types File type or list of types to be checked. param: string|array $list An array or string listing the types to check against. return: array Types not present in the list. |
| get_not_whitelisted() X-Ref |
| is_allowed_file_type($filename, $allowlist) X-Ref |
| Is the given filename of an allowed file type? Empty allowlist is interpreted as "any file type is allowed" rather than "no file can be uploaded". param: string $filename the file name param: string|array $allowlist list of allowed file extensions return: boolean True if the file type is allowed, false if not |
| get_unknown_file_types($types) X-Ref |
| Returns file types from the list that are not recognized param: string|array $types list of user-defined file types return: array A list of unknown file types. |
