DateIntervalType Field | ||
====================== | ||
|
||
.. versionadded:: 3.2 | ||
The DateIntervalType field type was introduced in Symfony 3.2. | ||
|
||
This field allows the user to select an *interval* of time. For example, if you want to | ||
allow the user to choose *how often* they receive a status email, they could use this | ||
field to choose intervals like every "10 minutes" or "3 days". | ||
|
||
The field can be rendered in a variety of different ways (see `widget`_) and can be configured to | ||
give you a ``DateInterval`` object, an `ISO 8601`_ duration string (e.g. ``P1DT12H``) | ||
or an array (see `input`_). | ||
|
||
+----------------------+----------------------------------------------------------------------------------+ | ||
| Underlying Data Type | can be ``DateInterval``, string or array (see the ``input`` option) | | ||
+----------------------+----------------------------------------------------------------------------------+ | ||
| Rendered as | single text box, multiple text boxes or select fields - see the `widget`_ option | | ||
+----------------------+----------------------------------------------------------------------------------+ | ||
| Options | - `days`_ | | ||
| | - `hours`_ | | ||
| | - `minutes`_ | | ||

|
||
Basic Usage | ||
----------- | ||
|
||
This field type is highly configurable, but easy to use. The most important | ||
options are `input`_ and `widget`_. | ||
|
||
You can configure *a lot* of different options, including exactly *which* range | ||
options to show (e.g. don't show "months", but *do* show "days"):: | ||
|
||
$builder->add('remindEvery', DateIntervalType::class, array( | ||
'widget' => 'integer', // render a text field for each part | ||
// 'input' => 'string', // if you want the field to return a ISO 8601 string back to you | ||
|
||
// customize which text boxes are shown | ||
'with_years' => false, | ||
'with_months' => false, | ||
'with_days' => true, | ||
'with_hours' => true, | ||
)); | ||
|
||
Field Options | ||
------------- | ||
|
||
days | ||
~~~~ | ||
|
||
**type**: ``array`` **default**: 0 to 31 | ||
|
||
List of days available to the days field type. This option is only relevant | ||
when the ``widget`` option is set to ``choice``:: | ||
|
||
'days' => range(1, 31) | ||
|
||
placeholder | ||
~~~~~~~~~~~ | ||
|
||
**type**: ``string`` or ``array`` | ||
|
||
If your widget option is set to ``choice``, then this field will be represented | ||
as a series of ``select`` boxes. The ``placeholder`` option can be used to | ||
add a "blank" entry to the top of each select box:: | ||
|
||
$builder->add('remindEvery', DateIntervalType::class, array( | ||
'placeholder' => '', | ||
)); | ||
|
||
Alternatively, you can specify a string to be displayed for the "blank" value:: | ||
|
||
$builder->add('remindEvery', DateIntervalType::class, array( | ||
'placeholder' => array('years' => 'Years', 'months' => 'Months', 'days' => 'Days') | ||
)); | ||
|
||
hours | ||
~~~~~ | ||
|
||
**type**: ``array`` **default**: 0 to 24 | ||
|
||
List of hours available to the hours field type. This option is only relevant | ||
when the ``widget`` option is set to ``choice``:: | ||
|
||
'hours' => range(1, 24) | ||
|
||
input | ||
~~~~~ | ||
|
||
**type**: ``string`` **default**: ``dateinterval`` | ||
|
||
The format of the *input* data - i.e. the format that the interval is stored on | ||
your underlying object. Valid values are: | ||
|
||
* ``string`` (a string formatted with `ISO 8601`_ standard, e.g. ``P7Y6M5DT12H15M30S``) | ||
* ``dateinterval`` (a ``DateInterval`` object) | ||
* ``array`` (e.g. ``array('days' => '1', 'hours' => '12',)``) | ||
|
||
The value that comes back from the form will also be normalized back into | ||
this format. | ||
|
||
minutes | ||
~~~~~~~ | ||
|
||
**type**: ``array`` **default**: 0 to 60 | ||
|
||
List of minutes available to the minutes field type. This option is only relevant | ||
when the ``widget`` option is set to ``choice``:: | ||
|
||
'minutes' => range(1, 60) | ||
|
||
months | ||
~~~~~~ | ||
|
||
**type**: ``array`` **default**: 0 to 12 | ||
|
||
List of months available to the months field type. This option is only relevant | ||
when the ``widget`` option is set to ``choice``:: | ||
|
||
'months' => range(1, 12) | ||
|
||
seconds | ||
~~~~~~~ | ||
|
||
**type**: ``array`` **default**: 0 to 60 | ||
|
||
List of seconds available to the seconds field type. This option is only relevant | ||
when the ``widget`` option is set to ``choice``:: | ||
|
||
'seconds' => range(1, 60) | ||
|
||
weeks | ||
~~~~~ | ||
|
||
**type**: ``array`` **default**: 0 to 52 | ||
|
||
List of weeks available to the weeks field type. This option is only relevant | ||
when the ``widget`` option is set to ``choice``:: | ||
|
||
'weeks' => range(1, 52) | ||
|
||
widget | ||
~~~~~~ | ||
|
||
**type**: ``string`` **default**: ``choice`` | ||
|
||
The basic way in which this field should be rendered. Can be one of the | ||
following: | ||
|
||
* ``choice``: renders one to six select inputs for years, months, weeks, days, | ||
hours, minutes and/or seconds, depending on the `with_years`_, `with_months`_, | ||
`with_weeks`_, `with_days`_, `with_hours`_, `with_minutes`_ and `with_seconds`_ | ||
options. | ||
Default: Three fields for years, months and days. | ||
|
||
* ``text``: renders one to six text inputs for years, months, weeks, days, | ||
hours, minutes and/or seconds, depending on the `with_years`_, `with_months`_, | ||
`with_weeks`_, `with_days`_, `with_hours`_, `with_minutes`_ and `with_seconds`_ | ||
options. | ||
Default: Three fields for years, months and days. | ||
|
||
* ``integer``: renders one to six integer inputs for years, months, weeks, days, | ||
hours, minutes and/or seconds, depending on the `with_years`_, `with_months`_, | ||
`with_weeks`_, `with_days`_, `with_hours`_, `with_minutes`_ and `with_seconds`_ | ||
options. | ||
Default: Three fields for years, months and days. | ||
|
||
* ``single_text``: renders a single input of type ``text``. User's input | ||
will be validated against the form ``PnYnMnDTnHnMnS`` (or ``PnW`` if using | ||
only weeks). | ||
|
||
with_days | ||
~~~~~~~~~ | ||
|
||
**type**: ``Boolean`` **default**: ``true`` | ||
|
||
Whether or not to include days in the input. This will result in an additional | ||
input to capture days. | ||
|
||
.. caution:: | ||
|
||
This can not be used when `with_weeks`_ is enabled. | ||
|
||
with_hours | ||
~~~~~~~~~~ | ||
|
||
**type**: ``Boolean`` **default**: ``false`` | ||
|
||
Whether or not to include hours in the input. This will result in an additional | ||

|
||
with_invert | ||
~~~~~~~~~~~ | ||
|
||
**type**: ``Boolean`` **default**: ``false`` | ||
|
||
Whether or not to include invert in the input. This will result in an additional | ||
checkbox. | ||
This can not be used when the `widget`_ option is set to ``single_text``. | ||
|
||
with_minutes | ||
~~~~~~~~~~~~ | ||
|
||
**type**: ``Boolean`` **default**: ``false`` | ||
|
||
Whether or not to include minutes in the input. This will result in an additional | ||
input to capture minutes. | ||
|
||
with_months | ||
~~~~~~~~~~~ | ||
|
||
**type**: ``Boolean`` **default**: ``true`` | ||
|
||
Whether or not to include months in the input. This will result in an additional | ||
input to capture months. | ||
|
||
with_seconds | ||
~~~~~~~~~~~~ | ||
|
||
**type**: ``Boolean`` **default**: ``false`` | ||
|
||
Whether or not to include seconds in the input. This will result in an additional | ||
input to capture seconds. | ||
|
||
with_weeks | ||
~~~~~~~~~~ | ||
|
||
**type**: ``Boolean`` **default**: ``false`` | ||
|
||
Whether or not to include weeks in the input. This will result in an additional | ||
input to capture weeks. | ||
|
||
.. caution:: | ||
|
||
This can not be used when `with_days`_ is enabled. | ||
|
||
with_years | ||
~~~~~~~~~~ | ||
|
||
