Fluid: dateFormat description is missing

[Gernott]

dateFormat is missing here: https://docs.typo3.org/other/typo3/view-helper-reference/main/en-us/Global/Format/Date.html

<f:form.textfield property="test.date" />
<f:form.hidden property="test.dateFormat" value="d.m.Y"/>

'test' is the property. dateFormat is a way in Fluid to set the needed Format of a f:form.textfield from type date.

@s2b Do you have any information on this? I have never seen it done before...

[s2b]

Me neither. I don't see how this is related to the format.date VH, seems like ExtBase magic to me.

[Gernott]

However - it is not documented ;)
And it's a super nice feature.

Where did you see that? Seems to me like the specific implementation of some Extension?

[Gernott]

It is TYPO3 core ;)
I found it in the Internet, 10 years ago I think. Sry, I don't know where.

Just use it in an extension. It works in every TYPO3 version since Extbase exists.
You can use any existing Extension with a date field and modify fluid to the example above.

If Simon Pretorious does not know about it it is very likely not a core feature. Please point us to the lines of code implementing this or provide a complete example
