Bug #88238
Updated by Ralf Zimmermann over 5 years ago
The ext:form setup contains some predefined mime types for the elements "FileUpload" and "ImageUpload"
* https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/form/Configuration/Yaml/BaseSetup.yaml#L254
* https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/form/Configuration/Yaml/BaseSetup.yaml#L260
Such predefined values are used as starting values while the form element is factorized:
* https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/form/Classes/Domain/Factory/ArrayFormFactory.php#L104
* https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/form/Classes/Domain/Model/FormElements/AbstractSection.php#L138
later on, the values from the form definition will be overlayed (https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/form/Classes/Domain/Model/FormElements/AbstractFormElement.php#L148):
* https://github.com/TYPO3/TYPO3.CMS/blob/master/typo3/sysext/form/Classes/Domain/Factory/ArrayFormFactory.php#L119
A form definition like this
<pre>
type: Form
identifier: test-1
label: test
prototypeName: standard
renderables:
-
type: Page
identifier: page-1
label: Step
renderables:
-
type: FileUpload
identifier: fileupload-1
label: 'File upload'
properties:
saveToFileMount: '1:/user_upload/'
allowedMimeTypes:
- application/pdf
</pre>
ends up in with the default ext:form setup, the result is a form element like this
<pre>
type: FileUpload
identifier: fileupload-1
label: 'File upload'
properties:
saveToFileMount: '1:/user_upload/'
allowedMimeTypes:
- application/msword
- application/vnd.openxmlformats-officedocument.wordprocessingml.document
- application/vnd.oasis.opendocument.text
- application/pdf
</pre>
We need to remove the predefined mime types from the ext:form setup-
