* the form context's isCreate() method returns false, a PUT request will be done.
* - `method` Set the form's method attribute explicitly.
* - `action` The controller action the form submits to, (optional). Use this option if you
* don't need to change the controller from the current request's controller. Deprecated since 3.2, use `url`.
* - `url` The URL the form submits to. Can be a string or a URL array. If you use 'url'
* you should leave 'action' undefined.
* - `encoding` Set the accept-charset encoding for the form. Defaults to `Configure::read('App.encoding')`
* - `enctype` Set the form encoding explicitly. By default `type => file` will set `enctype`
* to `multipart/form-data`.
* - `templates` The templates you want to use for this form. Any templates will be merged on top of
* the already loaded templates. This option can either be a filename in /config that contains
* the templates you want to load, or an array of templates to use.
* - `context` Additional options for the context class. For example the EntityContext accepts a 'table'
* option that allows you to set the specific Table class the form should be based on.
* - `idPrefix` Prefix for generated ID attributes.
* - `valueSources` The sources that values should be read from. See FormHelper::setValueSources()
* - `templateVars` Provide template variables for the formStart template.
*
* @param mixed $context The context for which the form is being defined.
* Can be a ContextInterface instance, ORM entity, ORM resultset, or an
* array of meta data. You can use false or null to make a context-less form.
* @param array $options An array of html attributes and options.
* @return string An formatted opening FORM tag.

*
* See each field type method for more information. Any options that are part of
* $attributes or $options for the different **type** methods can be included in `$options` for control().
* Additionally, any unknown keys that are not in the list below, or part of the selected type's options
* will be treated as a regular HTML attribute for the generated input.
*
* - `type` - Force the type of widget you want. e.g. `type => 'select'`
* - `label` - Either a string label, or an array of options for the label. See FormHelper::label().
* - `options` - For widgets that take options e.g. radio, select.
* - `error` - Control the error message that is produced. Set to `false` to disable any kind of error reporting (field
* error and error messages).
* - `empty` - String or boolean to enable empty select box options.
* - `nestedInput` - Used with checkbox and radio inputs. Set to false to render inputs outside of label
* elements. Can be set to true on any input to force the input inside the label. If you
* enable this option for radio buttons you will also need to modify the default `radioWrapper` template.
* - `templates` - The templates you want to use for this input. Any templates will be merged on top of
* the already loaded templates. This option can either be a filename in /config that contains
* the templates you want to load, or an array of templates to use.
* - `labelOptions` - Either `false` to disable label around nestedWidgets e.g. radio, multicheckbox or an array
* of attributes for the label tag. `selected` will be added to any classes e.g. `class => 'myclass'` where
* widget is checked
*
