Form/ File storages¶
EXT:form stores the form definitions within the file system and thus needs
write access to this storage. By default, the filemount
used. It is possible to configure a different and/ or an additional
filemount, which is then utilized for storing and reading forms.
The backend user will only see form definitions that are stored in
filemounts where the user has at least read access. The
form editor and
form plugin respect those access rights. In this way, you are able
to implement ACLs. If you have configured more than one filemount and the
backend user is able to access those, the
form manager will allow the
user to choose the preferred storage in which the form will be saved.
Even cooler, form definitions can be stored in and shipped with your custom extensions. If configured accordingly, the backend user will be able to embed those forms. Furthermore, you can configure that these form definitions:
- can be edited within the
- can be deleted with the help of the
By default, the aforementioned options are turned off. We decided to do so because having dynamic content within an extension - which is possibly version-controlled - is usually not a good idea. Furthermore, there is no ACL system available.
File uploads will be saved within filemounts as well. They are handled as FAL objects. The available filemounts for such uploads can be configured. When adding/ editing a file upload element, the backend user can select the desired upload storage.
In principle, files in filemounts are publicly accessible. If the uploaded files could contain sensitive data, you should suppress any HTTP access to the filemount. This may, for example, be achieved by creating a .htaccess file, assuming you are using an Apache web server. The directive of the .htaccess file is fairly easy:
Order deny,allow Deny from all
The following code block shows you how to configure additional filemounts for form definitions.
TYPO3: CMS: Form: persistenceManager: allowedFileMounts: # default filemount, no need to redeclare it again # just to show you the structure # 10: 1:/user_upload/ # additional filemounts 100: 1:/custom/forms/ 110: 2:/cloudstorage/forms/
The following code block shows you how to allow an extension path as an additional filemount for form definitions.
TYPO3: CMS: Form: persistenceManager: allowedExtensionPaths: 10: EXT:my_site_package/Resources/Private/Forms/
Add the following config if you want to allow backend users to edit forms stored within your own extension.
TYPO3: CMS: Form: persistenceManager: allowSaveToExtensionPaths: true
Add the following config if you want to allow backend users to delete forms stored within your own extension.
TYPO3: CMS: Form: persistenceManager: allowDeleteFromExtensionPaths: true
The following code blocks show you the default setup for filemounts that are used for file (and image) uploads.
