NotIdenticalTo ¶
Validates that a value is not identical to another value, defined in the options. To force that a value is identical, see IdenticalTo.
Caution
This constraint compares using !==
, so 3
and "3"
are
considered not equal. Use NotEqualTo to
compare with !=
.
Applies to | property or method |
Class | NotIdenticalTo |

Options ¶
groups
¶
type: array
| string
It defines the validation group or groups of this constraint. Read more about validation groups.
message
¶
type: string
default: This value should not be identical to {{ compared_value_type }} {{ compared_value }}.
This is the message that will be shown if the value is identical.
You can use the following parameters in this message:
Parameter | Description |
---|---|
{{ compared_value }} |
The expected value |
{{ compared_value_type }} |
The expected value type |
{{ value }} |
The current (invalid) value |
payload
¶
type: mixed
default: null
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.
For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
propertyPath
¶
type: string
It defines the object property whose value is used to make the comparison.
For example, if you want to compare the $endDate
property of some object
with regard to the $startDate
property of the same object, use
propertyPath="startDate"
in the comparison constraint of $endDate
.
Tip
When using this option, its value is available in error messages as the
{{ compared_value_path }}
placeholder. Although it's not intended to
include it in the error messages displayed to end users, it's useful when
using APIs for doing any mapping logic on client-side.
value
¶
type: mixed
[default option]
This option is required. It defines the comparison value. It can be a string, number or object.
