PHP Forms Options

Form options

method string: Form method (default: post)
method_field_name string: Name of the special method field when using methods other than GET and POST
action string: Form action (default: "")
layout string: Form layout ("plain", "table", "bootstrap" or an instance of FormLayout)
prefix mixed: Use custom prefix when generating names and ID
Other: All other options are passed directly to the form as attributes. Use it to specify attributes such as name, class, etc.

Default options

Default options for forms can be set by extending defaultOptions:

class MyForm extends Form {
	static protected function defaultOptions(){
		return [
			'layout' => 'bootstrap',
		];
	}
};
 
MyForm::create("example_default_options", function($f){
	$f->textField('name', 'My field name');
});

Field options

hint string: Description of the field. (default: none)
Other: All other attributes is passed directly to field, allowing custom attributes such as placeholder, title, etc.

Upload field

remove boolean: Adds a removal checkbox (e.g. a user avatar which is set if file is uploaded but retained if nothing is sent and removed if checkbox is checked) (default: false)
current html: HTML to preview the current uploaded data, e.g. <img src="/user/123/avatar.png"/>. (default: none)

Serialization

Most attributes is serialized using these rules:

['foo' => 'bar'] becomes foo="bar"
['foo' => ['a', 'b', 'c']] becomes foo="a b c" (order preserved)
['foo' => ['spam => 'ham']] becomes foo-spam="ham" (deeper nesting is ok)
