DateTimeDiff

• DateTimeDiff("years"|"months"|"days"|"hours"|"minutes"|"seconds"|"microseconds" $type, Validator $validator)
• DateTimeDiff("years"|"months"|"days"|"hours"|"minutes"|"seconds"|"microseconds" $type, Validator $validator, string $format)
• DateTimeDiff("years"|"months"|"days"|"hours"|"minutes"|"seconds"|"microseconds" $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()).

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

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}} and
inverted	The number of {{type|trans}} between {{now}} and

DateTimeDiff::TEMPLATE_NOT_A_DATE

Mode	Template
default	For comparison with {{now|raw}}, {{subject}} must be a valid datetime
inverted	For comparison with {{now|raw}}, {{subject}} must not be a valid datetime

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 as prefix

The template serves as a prefix to the template of the inner validator.

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

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:

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.
