Success

offsetGet()

Implements $entity[$offset];


    public
                &    offsetGet(string $offset) : mixed

Parameters

$offset : string: The offset to get.

#[ReturnTypeWillChange]

offsetSet()

Implements $entity[$offset] = $value;


    public
                    offsetSet(string $offset, mixed $value) : void

Parameters

$offset : string: The offset to set.
$value : mixed: The value to set.

offsetUnset()

Implements unset($result[$offset]);


    public
                    offsetUnset(string $offset) : void

Parameters

$offset : string: The offset to remove.

set()

Sets a single field inside this entity.


    public
                    set(array<string, mixed>|string $field[, mixed $value = null ][, array<string, mixed> $options = [] ]) : $this

Example:

$entity->set('name', 'Andrew');

It is also possible to mass-assign multiple fields to this entity with one call by passing a hashed array as fields in the form of field => 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 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');

Parameters

$field : array<string, mixed>|string: the name of field to set or a list of fields with their respective values
$value : mixed = null: 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
$options : array<string, mixed> = []: Options to be used for setting the field. Allowed option keys are setter and guard

Return values

$this

setAccess()

Stores whether a field value can be changed or set in this entity.


    public
                    setAccess(array<string|int, string>|string $field, bool $set) : $this

The special field * can also be marked as accessible or protected, meaning that any other field specified before will take its value. For example $entity->setAccess('*', true) means that any field not specified already will be accessible by default.

You can also call this method with an array of fields, in which case they will each take the accessibility value specified in the second argument.

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 fields as accessible
$entity->setAccess('*', false); // Mark all fields as protected

Parameters

$field : array<string|int, string>|string: Single or list of fields to change its accessibility
$set : bool: True marks the field as accessible, false will mark it as protected.

Return values

$this
