Hi everyone and especially SF/SFI developers!
I've just finished the pre-alpha version of the new Semantic Form Input for
selecting multiple items in a comfortable way.
You can see the demo here:
http://test12.wikivote.ru/index.php?title=D&action=formedit
I want to write a piece of technical documentation for myself and for
future generations of SFInput writers but I don't yet understand several
imporant things about Form Inputs. I'd be very glad if Semantic Forms
developers clarified something for me.
== Question 1. History and future plans ==
As far as I can tell from the code there are three generations of
FormInputs exist now, am I right?
1) in the past input developer had to override getHTML() function. It's
done in most Semantic Forms's formsinput but it's not a good way anymore.
We also have used
2) now it's the era of the Resource Loader and to create my input I have to
override getHtmlText, getResourceModuleNames and getJsInitFunctionData
functions. For figuring out what kind of data can be handled by the input
we now use getHandledPropertyTypes function instead
of getDefaultPropTypes, getDefaultPropTypeLists
and getOtherPropTypesHandled.
3) In the future addJsInitFunctionData, addJsValidationFunctionData will be
used by the internals of the Semantic Forms and all deprecated methods will
be removed.
== Question 2. Naming ==
Is it correct that I have to name my inputs like that: "input_" .
$this->mInputNumber
== Question 3 Naming again ==
What the 'name' attribute is used for? The rule of the thumb is of course
that you always make it like that: $this->mInputName
== Question 4. Handling lists ==
I'm not sure that I understand about handling lists issues in Form Inputs.
1) The Name attribute of the form input sometimes have brackets like in it
like this: input3[].
2) On the other hand sometimes we add an additional hidden element like
Html::hidden($name . '[is_list]', 1)
3) And thirdly we have the method canHandleLists() to override.
It seems that all three thing are indicating that the form input can handle
lists, but it's pretty weird to see three different pieces of code trying
to say the same thing. What's happening
== Question 5. Don't draw my input without proper CSS! ==
When the form is loaded there's a period of time when the user can my
element undressed. Namely the user can see he input without any CSS applied
to it. How can I avoid such an effect?
== Question 6. Be part of something bigger ==
Is it possible that my code will be part of Semantic Forms Inputs or
Semantic Forms? If so, what versions of SMW, SF, SFI should I use for
testing? What versions I have to be compatible with?
Cheers!
