Feature: #88238 - FeatureToggle: form.legacyUploadMimeTypes¶
See forge#88238
Description¶
The feature toggle form.legacyUploadMimeTypes
makes it possible to enable some predefined allowedMimeTypes
in FileUpload
and ImageUpload
form elements.
These MIME types are enabled through this feature toggle by default as of TYPO3v10 and will be removed completely in TYPO3v11.
Impact¶
Full control over file upload MIME type validation can be achieved by disabling this flag and explicitly listing all allowed MIME types.
