* ```

|

* ```
|
|
*
|
|
* It is also possible to mass-assign multiple fields to this entity

* field => value pairs
|

|
|
*
|
|
* ```
|
|
* $entity->set(['name' => 'andrew', 'id' => 1]);

* echo $entity->name // prints andrew

|

*
|
|
* Some times it is handy to bypass setter functions in this entity when assigning
|
|
* fields. You can achieve this by disabling the `setter` option using the

* `$options` parameter:
|
|
*
|
|
* ```
|
|
* $entity->set('name', 'Andrew', ['setter' => false]);
|
|
* $entity->set(['name' => 'Andrew', 'id' => 1], ['setter' => false]);
|
|
* ```
|
|
*
|
|
* Mass assignment should be treated carefully when accepting user input, by default
|
|
* entities will guard all fields when fields are assigned in bulk. You can disable
|
|
* the guarding for a single set call with the `guard` option:
|
|
*
|
|
* ```
|
|
* $entity->set(['name' => 'Andrew', 'id' => 1], ['guard' => false]);
|
|
* ```
|
|
*
|
|
* You do not need to use the guard option when assigning fields individually:
|
|
*
|
|
* ```
|
|
* // No need to use the guard option.
|
|
* $entity->set('name', 'Andrew');
|
|
* ```
|
|
*
|
|
* @param array<string, mixed>|string $field the name of field to set or a list of
|
|
* fields with their respective values
|
|
* @param mixed $value The value to set to the field or an array if the
|
|
* first argument is also an array, in which case will be treated as $options
|
