Returns
accessible() public ¶
accessible( string|array $property , boolean|null $set null )
Stores whether or not a property value can be changed or set in this entity.
The special property *
can also be marked as accessible or protected, meaning
that any other property specified before will take its value. For example
$entity->accessible('*', true)
means that any property not specified already
will be accessible by default.
You can also call this method with an array of properties, in which case they will each take the accessibility value specified in the second argument.
Example:
$entity->accessible('id', true); // Mark id as not protected $entity->accessible('author_id', false); // Mark author_id as protected $entity->accessible(['id', 'user_id'], true); // Mark both properties as accessible $entity->accessible('*', false); // Mark all properties as protected
When called without the second param it will return whether or not the property can be set.
Example:
$entity->accessible('id'); // Returns whether it can be set or not
Deprecated
Parameters
- string|array $property
- single or list of properties to change its accessibility
- boolean|null $set optional null
true marks the property as accessible, false will mark it as protected.
Returns
$this|bool
clean() public ¶
clean( )
Sets the entire entity as clean, which means that it will appear as no properties being modified or added at all. This is an useful call for an initial object hydration
dirty() public ¶
dirty( string|null $property null , null|boolean $isDirty null )
Sets the dirty status of a single property. If called with no second argument, it will return whether the property was modified or not after the object creation.

errors( string|array|null $field null , string|array|null $errors null , boolean $overwrite false )
Sets the error messages for a field or a list of fields. When called without the second argument it returns the validation errors for the specified fields. If called with no arguments it returns all the validation error messages stored in this entity and any other nested entity.
Example
// Sets the error messages for a single field $entity->errors('salary', ['must be numeric', 'must be a positive number']); // Returns the error messages for a single field $entity->getErrors('salary'); // Returns all error messages indexed by field name $entity->getErrors(); // Sets the error messages for multiple fields at once $entity->getErrors(['salary' => ['message'], 'name' => ['another message']);
When used as a setter, this method will return this entity instance for method chaining.

Whether or not the entity has been persisted.
jsonSerialize() public ¶
jsonSerialize( )
Returns the properties that will be serialized as JSON
Returns
offsetExists() public ¶
offsetExists( mixed $offset )
Implements isset($entity);
Parameters
- mixed $offset
- The offset to check.
Returns
Success
offsetGet() public ¶
offsetGet( mixed $offset )
Implements $entity[$offset];
Parameters
- mixed $offset
- The offset to get.
Returns
offsetSet() public ¶
offsetSet( mixed $offset , mixed $value )
Implements $entity[$offset] = $value;
Parameters
- mixed $offset
- The offset to set.
- mixed $value
- The value to set.
offsetUnset() public ¶
offsetUnset( mixed $offset )
Implements unset($result[$offset]);
Parameters
- mixed $offset
- The offset to remove.
set() public ¶
set( string|array $property , mixed $value null , array $options [] )
Sets a single property inside this entity.
Example:
$entity->set('name', 'Andrew');
It is also possible to mass-assign multiple properties to this entity with one call by passing a hashed array as properties in the form of property => value pairs
Example:
$entity->set(['name' => 'andrew', 'id' => 1]); echo $entity->name // prints andrew echo $entity->id // prints 1
Some times it is handy to bypass setter functions in this entity when assigning
properties. 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 properties 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' => true]);
You do not need to use the guard option when assigning properties individually:
// No need to use the guard option. $entity->set('name', 'Andrew');
Parameters
- string|array $property
the name of property to set or a list of properties with their respective values
- mixed $value optional null
The value to set to the property or an array if the first argument is also an array, in which case will be treated as $options
- array $options optional []
options to be used for setting the property. Allowed option keys are
setter
andguard
Returns
$this
Throws
setAccess() public ¶
setAccess( string|array $property , boolean $set )

$entity->setAccess('*', true)

will be accessible by default.

Example:
$entity->setAccess('id', true); // Mark id as not protected $entity->setAccess('author_id', false); // Mark author_id as protected $entity->setAccess(['id', 'user_id'], true); // Mark both properties as accessible $entity->setAccess('*', false); // Mark all properties as protected
