The value does not match another field in $data.
equals()  : bool
Equals the static value provided.

The field value.

$param : string|null = null

The rule's parameter.

$data : array<string|int, mixed> = []

The data to be validated.

$error : string|null = null
$field : string|null = null

The field name.

Return values
bool

greater_than()

Greater than

public greater_than(string|null $str, string $min) : bool
Parameters
$str : string|null
$min : string
Return values
bool

greater_than_equal_to()

Equal to or Greater than

public greater_than_equal_to(string|null $str, string $min) : bool
Parameters
$str : string|null

Return values
bool

in_list()

Value should be within an array of values

public in_list(string|null $value, string $list) : bool
Parameters

is_not_unique()

Checks the database to see if the given value exist.

public is_not_unique(string|null $str, string $field, array<string|int, mixed> $data) : bool

$data : array<string|int, mixed>
Return values
bool

is_unique()

Checks the database to see if the given value is unique. Can ignore a single record by field/value to make it useful during record updates.

public is_unique(string|null $str, string $field, array<string|int, mixed> $data) : bool

Example: is_unique[table.field,ignore_field,ignore_value] is_unique[users.email,id,5]
