Documenting all missing options

[wouterj]

The Form Type Reference has some missing options.

How to document it

Most of the missing options are already documented. You should check in the reference/forms/types/options/ directory to find if the option is already documented and if the description is correct for this type. If it is, you should add an include statement in the type reference article:

.. include:: /reference/forms/types/options/read_only.rst.inc

If the description is not correct for this type, you need to document it in the type reference article:

error_bubbling
~~~~~~~~~~~~~~
**type**: ``boolean`` **default**: ``false``

    
Some description and usage of the type.

If there is no documentation about the option and it is used in other types, you should create a new file in the reference/forms/types/options/ directory and include it in the relevant articles.

The Missing Options in 2.0

The options are all linked to the place where they are defined in the core code. However, search in the class to find some usage and other important information about the option you're documenting.

DateTime

• widget (allowed
  values)
• empty_value

Field

• data_class
• read_only
• max_length
• pattern
• by_reference
• error_bubbling
• error_mapping
• label
• invalid_message
• invalid_message_parameters
• the disabled option should get removed

Form

• virtual

Integer

• precision
  (the docs already exists in the Number type, just create a
  precision.rst.inc and include it in both)

Time

• empty_value

• DateTime
  • empty_value
• Integer
  • precision
• Number
  • precision
• Time
  • empty_value

thanks @xabbuh, updated the PR

[xabbuh]

What do we do with the Field options as it is not part of Symfony since 2.1?

[stof]

@xabbuh they are part of Symfony, but in the form type

[xabbuh]

I know. I think my question was not clear enough. I'm wondering if this list also applies to the FormType? Specifically, why should the disabled option be removed?

[wouterj]

@xabbuh disabled was added in 2.1, not 2.0.

This list does not fully apply to 2.1.

[xabbuh]

So that's not a problem anymore.

I'll walk through the list one by one and will provide an updated list.

[stof]

@wouterj for 2.0, disabled was the same option than read_only in 2.1+

[xabbuh]

The following options need to be documented:

• data_class
• empty_data
• max_length
• pattern
• by_reference
• error_bubbling
• label
• label_attr
• compound

I think some options are already documented. So it's an updated list:

• data_class (Create data_class.rst.inc #2362 #3334)
• empty_data
• pattern
• by_reference
• label_attr ([#2362] Documentation for label_attr option in Form Compontent #3337)
• compound (Create compound.rst.inc #2362 #3336)
