# DateTimeDiff
|
|
|
|
- `DateTimeDiff(string $type, Validator $validator)`
|
|
- `DateTimeDiff(string $type, Validator $validator, string $format)`
|
|
- `DateTimeDiff(string $type, Validator $validator, string $format, DateTimeImmutable $now)`
|
|
|
|
Validates the difference of date/time against a specific validator.
|
|
|
|
The `$format` argument should follow PHP's [date()][] function. When the `$format` is not given, this validator accepts
|
|
[Supported Date and Time Formats][] by PHP (see [strtotime()][]).
|
|
|
|
```php
|
|
v::dateTimeDiff('years', v::equals(7))->isValid('7 years ago'); // true
|
|
v::dateTimeDiff('years', v::equals(7))->isValid('7 years ago + 1 minute'); // false
|
|
|
|
v::dateTimeDiff('years', v::greaterThan(18), 'd/m/Y')->isValid('09/12/1990'); // true
|
|
v::dateTimeDiff('years', v::greaterThan(18), 'd/m/Y')->isValid('09/12/2023'); // false
|
|
|
|
v::dateTimeDiff('months', v::between(1, 18))->isValid('5 months ago'); // true
|
|
```
|
|
|
|
The supported types are:
|
|
|
|
- `years`
|
|
- `months`
|
|
- `days`
|
|
- `hours`
|
|
- `minutes`
|
|
- `seconds`
|
|
- `microseconds`
|
|
|
|
## Templates
|
|
|
|
The first two templates serve as message suffixes:
|
|
|
|
```php
|
|
v::dateTimeDiff('years', v::equals(2))->assert('1 year ago')
|
|
// The number of years between now and 1 year ago must be equal to 2
|
|
|
|
v::not(v::dateTimeDiff('years', v::lessThan(8)))->assert('7 year ago')
|
|
// The number of years between now and 7 year ago must not be less than 8
|
|
```
|
|
|
|
### `DateTimeDiff::TEMPLATE_STANDARD`
|
|
|
|
Used when `$format` and `$now` are not defined.
|
|
|
|
| Mode | Template |
|
|
| ---------- | ------------------------------------------------- |
|
|
| `default` | The number of {{type|trans}} between now and |
|
|
| `inverted` | The number of {{type|trans}} between now and |
|
|
|
|
### `DateTimeDiff::TEMPLATE_CUSTOMIZED`
|
|
|
|
Used when `$format` or `$now` are defined.
|
|
|
|
| Mode | Template |
|
|
| ---------- | -------------------------------------------------------------- |
|
|
| `default` | The number of {{type|trans}} between {{now|raw}} and |
|
|
| `inverted` | The number of {{type|trans}} between {{now|raw}} and |
|
|
|
|
### `DateTimeDiff::TEMPLATE_WRONG_FORMAT`
|
|
|
|
Used when the input cannot be parsed with the given format.
|
|
|
|
| Mode | Template |
|
|
| ---------- | ---------------------------------------------------------------------------------------------------------------- |
|
|
| `default` | For comparison with {{now|raw}}, {{subject}} must be a valid datetime in the format {{sample|raw}} |
|
|
| `inverted` | For comparison with {{now|raw}}, {{subject}} must not be a valid datetime in the format {{sample|raw}} |
|
|
|
|
## Template placeholders
|
|
|
|
| Placeholder | Description |
|
|
| ----------- | ---------------------------------------------------------------- |
|
|
| `subject` | The validated input or the custom validator name (if specified). |
|
|
| `now` | The date and time that is considered as now. |
|
|
| `sample` | A sample of the datetime. |
|
|
| `type` | The type of interval (years, months, etc.). |
|
|
|
|
## Caveats
|
|
|
|
When using custom templates, the key must be `dateTimeDiff` + name of the validator you passed, for example:
|
|
|
|
```php
|
|
v::dateTimeDiff('years', v::equals(2))->assert('1 year ago', [
|
|
'dateTimeDiffEquals' => 'Please enter a date that is 2 years ago'
|
|
]);
|
|
// Please enter a date that is 2 years ago.
|
|
```
