money Field Type
Renders an input text field and specializes in handling submitted "money" data.
This field type allows you to specify a currency, whose symbol is rendered next to the text field. There are also several other options for customizing how the input and output of the data is handled.
Field Options
currency
type: string
default: EUR
Specifies the currency that the money is being specified in. This determines the currency symbol that should be shown by the text box. Depending on the currency - the currency symbol may be shown before or after the input text field.
This can be any 3 letter ISO 4217 code. You can also set this to false to hide the currency symbol.
divisor
type: integer
default: 1
If, for some reason, you need to divide your starting value by a number
before rendering it to the user, you can use the divisor
option.
For example:
1 2 3
$builder->add('price', 'money', array(
'divisor' => 100,
));
In this case, if the price
field is set to 9900
, then the value
99
will actually be rendered to the user. When the user submits the
value 99
, it will be multiplied by 100
and 9900
will ultimately
be set back on your object.
precision
type: integer
default: 2
For some reason, if you need some precision other than 2 decimal places,
you can modify this value. You probably won't need to do this unless,
for example, you want to round to the nearest dollar (set the precision
to 0
).
grouping
type: integer
default: false
This value is used internally as the NumberFormatter::GROUPING_USED
value when using PHP's NumberFormatter
class. Its documentation is non-existent, but it appears that if you set this to true
, numbers will be grouped with a comma or period (depending on your locale): 12345.123
would display as 12,345.123
.
Inherited Options
These options inherit from the field type:
required
type: Boolean
default: true
If true, an HTML5 required attribute will be rendered. The corresponding
label
will also render with a required
class.
This is superficial and independent from validation. At best, if you let Symfony guess your field type, then the value of this option will be guessed from your validation information.
label
type: string
default: The label is "guessed" from the field name
Sets the label that will be used when rendering the field. The label can also be directly set inside the template:
1
{{ form_label(form.name, 'Your name') }}
read_only
type: Boolean
default: false
If this option is true, the field will be rendered with the disabled
attribute so that the field is not editable.
error_bubbling
type: Boolean
default: false
If true, any errors for this field will be passed to the parent field or form. For example, if set to true on a normal field, any errors for that field will be attached to the main form, not to the specific field.
invalid_message
type: string
default: This value is not valid
This is the validation error message that's used if the data entered into this field doesn't make sense (i.e. fails validation).
This might happen, for example, if the user enters a nonsense string into
a time field that cannot be converted
into a real time or if the user enters a string (e.g. apple
) into a
number field.
Normal (business logic) validation (such as when setting a minimum length for a field) should be set using validation messages with your validation rules (reference).
invalid_message_parameters
type: array
default: array()
When setting the invalid_message
option, you may need to
include some variables in the string. This can be done by adding placeholders
to that option and including the variables in this option:
1 2 3 4 5
$builder->add('some_field', 'some_type', array(
// ...
'invalid_message' => 'You entered an invalid value - it should include %num% letters',
'invalid_message_parameters' => array('%num%' => 6),
));
