Class Table

Represents a single database table.

Exposes methods for retrieving data out of it, and manages the associations this table has to other tables. Multiple instances of this class can be created for the same database table with different aliases, this allows you to address your database structure in a richer and more expressive way.

Retrieving data

The primary way to retrieve data is using Table::find(). See that method for more information.

Dynamic finders

In addition to the standard find($type) finder methods, CakePHP provides dynamic finder methods. These methods allow you to easily set basic conditions up. For example to filter users by username you would call

$query = $users->findByUsername('mark');

You can also combine conditions on multiple fields using either Or or And:

$query = $users->findByUsernameOrEmail('mark', '[email protected]');

Bulk updates/deletes

You can use Table::updateAll() and Table::deleteAll() to do bulk updates/deletes. You should be aware that events will not be fired for bulk updates/deletes.

Callbacks/events

Table objects provide a few callbacks/events you can hook into to augment/replace find operations. Each event uses the standard event subsystem in CakePHP

beforeFind(Event $event, Query $query, ArrayObject $options, boolean $primary) Fired before each find operation. By stopping the event and supplying a return value you can bypass the find operation entirely. Any changes done to the $query instance will be retained for the rest of the find. The $primary parameter indicates whether or not this is the root query, or an associated query.
buildValidator(Event $event, Validator $validator, string $name) Allows listeners to modify validation rules for the provided named validator.
buildRules(Event $event, RulesChecker $rules) Allows listeners to modify the rules checker by adding more rules.
beforeRules(Event $event, EntityInterface $entity, ArrayObject $options, string $operation) Fired before an entity is validated using the rules checker. By stopping this event, you can return the final value of the rules checking operation.
afterRules(Event $event, EntityInterface $entity, ArrayObject $options, bool $result, string $operation) Fired after the rules have been checked on the entity. By stopping this event, you can return the final value of the rules checking operation.
beforeSave(Event $event, EntityInterface $entity, ArrayObject $options) Fired before each entity is saved. Stopping this event will abort the save operation. When the event is stopped the result of the event will be returned.
afterSave(Event $event, EntityInterface $entity, ArrayObject $options) Fired after an entity is saved.
afterSaveCommit(Event $event, EntityInterface $entity, ArrayObject $options) Fired after the transaction in which the save operation is wrapped has been committed. It’s also triggered for non atomic saves where database operations are implicitly committed. The event is triggered only for the primary table on which save() is directly called. The event is not triggered if a transaction is started before calling save.
beforeDelete(Event $event, EntityInterface $entity, ArrayObject $options) Fired before an entity is deleted. By stopping this event you will abort the delete operation.
afterDelete(Event $event, EntityInterface $entity, ArrayObject $options) Fired after an entity has been deleted.

Namespace: Cake\ORM
See: \Cake\Event\EventManager for reference on the events system.

strategy: The strategy to be used for selecting results Either 'select' or 'subquery'. If subquery is selected the query used to return results in the source table will be used as conditions for getting rows in the target table.
saveStrategy: Either 'append' or 'replace'. Indicates the mode to be used for saving associated entities. The former will only create new links between both side of the relation and the latter will do a wipe and replace to create the links between the passed entities when saving.
strategy: The loading strategy to use. 'select' and 'subquery' are supported.
finder: The finder method to use when loading records from this association. Defaults to 'all'.

Options

atomic Defaults to true. When true the deletion happens within a transaction.
checkRules Defaults to true. Check deletion rules before deleting the record.

Events

Model.beforeDelete Fired before the delete occurs. If stopped the delete will be aborted. Receives the event, entity, and options.
Model.afterDelete Fired after the delete has been successful. Receives the event, entity, and options.
Model.afterDeleteCommit Fired after the transaction is committed for an atomic delete. Receives the event, entity, and options.

When calling this finder, the fields passed are used to determine what should be used as the array key, value and optionally what to group the results by. By default the primary key for the model is used for the key, and the display field as value.

The results of this finder will be in the following form:

[
 1 => 'value for id 1',
 2 => 'value for id 2',
 4 => 'value for id 4'
]

You can specify which property will be used as the key and which as value by using the $options array, when not specified, it will use the results of calling primaryKey and displayField respectively in this table:

$table->find('list', [
 'keyField' => 'name',
 'valueField' => 'age'
]);

Results can be put together in bigger groups when they share a property, you can customize the property to use for grouping by setting groupField:

$table->find('list', [
 'groupField' => 'category_id',
]);

When using a groupField results will be returned in this format:

[
 'group_1' => [
     1 => 'value for id 1',
     2 => 'value for id 2',
 ]
 'group_2' => [
     4 => 'value for id 4'

If no record can be found, a new entity will be created with the $search properties. If a callback is provided, it will be called allowing you to define additional default values. The new entity will be saved and returned.

If your find conditions require custom order, associations or conditions, then the $search parameter can be a callable that takes the Query as the argument, or a \Cake\ORM\Query object passed as the $search parameter. Allowing you to customize the find results.

Options

The options array is passed to the save method with exception to the following keys:

atomic: Whether to execute the methods for find, save and callbacks inside a database transaction (default: true)
defaults: Whether to use the search criteria as default values for the new entity (default: true)

Values belonging to a parent row based on their parent_id value will be recursively nested inside the parent row values using the children property

You can customize what fields are used for nesting results, by default the primary key and the parent_id fields are used. If you wish to change these defaults you need to provide the keys keyField, parentField or nestingKey in $options:

$table->find('threaded', [
 'keyField' => 'id',
 'parentField' => 'ancestor_id'
 'nestingKey' => 'children'
]);

Returns the validation rules tagged with $name. It is possible to have multiple different named validation sets, this is useful when you need to use varying rules when saving from different routines in your system.

If a validator has not been set earlier, this method will build a valiator using a method inside your class.

For example, if you wish to create a validation set called 'forSubscription', you will need to create a method in your Table subclass as follows:

public function validationForSubscription($validator)
{

  $this->request->getData(),
  ['associated' => ['Tags', 'Comments.Users']]
);

You can limit fields that will be present in the constructed entities by passing the fields option, which is also accepted for associations:

$articles = $this->Articles->newEntities($this->request->getData(), [
 'fields' => ['title', 'body', 'tags', 'comments'],
 'associated' => ['Tags', 'Comments.Users' => ['fields' => 'username']]
 ]
);

You can use the Model.beforeMarshal event to modify request data before it is converted into entities.

Parameters

newEntity() ¶ public

newEntity(array|null $data = null, array $options = []): Cake\Datasource\EntityInterface

Create a new entity + associated entities from an array.

By default all the associations on this table will be hydrated. You can limit which associations are built, or include deeper associations using the options parameter:

$article = $this->Articles->newEntity(
  $this->request->getData(),
  ['associated' => ['Tags', 'Comments.Users']]
);

You can limit fields that will be present in the constructed entity by passing the fields option, which is also accepted for associations:

$article = $this->Articles->newEntity($this->request->getData(), [
 'fields' => ['title', 'body', 'tags', 'comments'],
 'associated' => ['Tags', 'Comments.Users' => ['fields' => 'username']]
]
);

The fields option lets remove or restrict input data from ending up in the entity. If you'd like to relax the entity's default accessible fields, you can use the accessibleFields option:

$article = $this->Articles->newEntity(
  $this->request->getData(),
  ['accessibleFields' => ['protected_field' => true]]
);

By default, the data is validated before being passed to the new entity. In the case of invalid fields, those will not be present in the resulting object. The validate option can be used to disable validation on the passed data:

$article = $this->Articles->newEntity(
  $this->request->getData(),
  ['validate' => false]
);

You can also pass the name of the validator to use in the validate option. If null is passed to the first param of this function, no validation will be performed.

You can use the Model.beforeMarshal event to modify request data before it is converted into entities.

Parameters

array|null $data optional
array $options optional

Returns

Cake\Datasource\EntityInterface

patchEntities() ¶ public

patchEntities(Cake\Datasource\EntityInterface[]|Traversable $entities, array $data, array $options = []): Cake\Datasource\EntityInterface[]

Merges each of the elements passed in $data into the entities found in $entities respecting the accessible fields configured on the entities. Merging is done by matching the primary key in each of the elements in $data and $entities.

Those entries in $entities that cannot be matched to any record in $data will be discarded. Records in $data that could not be matched will be marshalled as a new entity.

When merging HasMany or BelongsToMany associations, all the entities in the $data array will appear, those that can be matched by primary key will get the data merged, but those that cannot, will be discarded.

You can limit fields that will be present in the merged entities by passing the fields option, which is also accepted for associations:

$articles = $this->Articles->patchEntities($articles, $this->request->getData(), [
 'fields' => ['title', 'body', 'tags', 'comments'],
 'associated' => ['Tags', 'Comments.Users' => ['fields' => 'username']]
 ]
);

patchEntity() ¶ public

patchEntity(Cake\Datasource\EntityInterface $entity, array $data, array $options = []): Cake\Datasource\EntityInterface

Merges the passed $data into $entity respecting the accessible fields configured on the entity. Returns the same entity after being altered.

You can limit fields that will be present in the merged entity by passing the fields option, which is also accepted for associations:

$article = $this->Articles->patchEntity($article, $this->request->getData(), [
 'fields' => ['title', 'body', 'tags', 'comments'],
 'associated' => ['Tags', 'Comments.Users' => ['fields' => 'username']]
 ]
);

By default, the data is validated before being passed to the entity. In the case of invalid fields, those will not be assigned to the entity. The validate option can be used to disable validation on the passed data:

$article = $this->patchEntity($article, $this->request->getData(),[
 'validate' => false
]);

You can use the Model.beforeMarshal event to modify request data before it is converted into entities.

When patching scalar values (null/booleans/string/integer/float), if the property presently has an identical value, the setter will not be called, and the property will not be marked as dirty. This is an optimization to prevent unnecessary field updates when persisting entities.

save(Cake\Datasource\EntityInterface $entity, array|ArrayAccess $options = []): Cake\Datasource\EntityInterface|false

Persists an entity based on the fields that are marked as dirty and returns the same entity after a successful save or false in case of any error.

Options

The options array accepts the following keys:

atomic: Whether to execute the save and callbacks inside a database transaction (default: true)
checkRules: Whether or not to check the rules on entity before saving, if the checking fails, it will abort the save operation. (default:true)
associated: If true it will save 1st level associated entities as they are found in the passed $entity whenever the property defined for the association is marked as dirty. If an array, it will be interpreted as the list of associations to be saved. It is possible to provide different options for saving on associated table objects using this key by making the custom options the array value. If false no associated records will be saved. (default: true)
checkExisting: Whether or not to check if the entity already exists, assuming that the entity is marked as not new, and the primary key has been set.

Events

When saving, this method will trigger four events:

Model.beforeRules: Will be triggered right before any rule checking is done for the passed entity if the checkRules key in $options is not set to false. Listeners will receive as arguments the entity, options array and the operation type. If the event is stopped the rules check result will be set to the result of the event itself.
Model.afterRules: Will be triggered right after the checkRules() method is called for the entity. Listeners will receive as arguments the entity, options array, the result of checking the rules and the operation type. If the event is stopped the checking result will be set to the result of the event itself.
Model.beforeSave: Will be triggered just before the list of fields to be persisted is calculated. It receives both the entity and the options as arguments. The options array is passed as an ArrayObject, so any changes in it will be reflected in every listener and remembered at the end of the event so it can be used for the rest of the save operation. Returning false in any of the listeners will abort the saving process. If the event is stopped using the event API, the event object's result property will be returned. This can be useful when having your own saving strategy implemented inside a listener.
Model.afterSave: Will be triggered after a successful insert or save, listeners will receive the entity and the options array as arguments. The type of operation performed (insert or update) can be determined by checking the entity's method isNew, true meaning an insert and false an update.
Model.afterSaveCommit: Will be triggered after the transaction is committed for atomic save, listeners will receive the entity and the options array as arguments.

This method will determine whether the passed entity needs to be inserted or updated in the database. It does that by checking the isNew method on the entity. If the entity to be saved returns a non-empty value from its errors() method, it will not be saved.

Saving on associated tables

This method will by default persist entities belonging to associated tables, whenever a dirty property matching the name of the property name set for an association in this table. It is possible to control what associations will be saved and to pass additional option for saving them.

// Only save the comments association
$articles->save($entity, ['associated' => ['Comments']]);

// Save the company, the employees and related addresses for each of them.
// For employees do not check the entity rules
$companies->save($entity, [
  'associated' => [
    'Employees' => [
      'associated' => ['Addresses'],
      'checkRules' => false
    ]
  ]
]);

// Save no associations
$articles->save($entity, ['associated' => false]);

validateUnique() ¶ public

validateUnique(mixed $value, array $options, array|null $context = null): bool

Validator method used to check the uniqueness of a value for a column. This is meant to be used with the validation API and not to be called directly.

Example:

$validator->add('email', [
 'unique' => ['rule' => 'validateUnique', 'provider' => 'table']
])

Unique validation can be scoped to the value of another column:

$validator->add('email', [
 'unique' => [
     'rule' => ['validateUnique', ['scope' => 'site_id']],
     'provider' => 'table'
 ]
]);

In the above example, the email uniqueness will be scoped to only rows having the same site_id. Scoping will only be used if the scoping field is present in the data to be validated.

Parameters

mixed $value: The value of column to be checked for uniqueness.
array $options: The options array, optionally containing the 'scope' key. May also be the validation context, if there are no options.
array|null $context optional: Either the validation context or null.

Returns

bool

validationDefault() ¶ public

validationDefault(Cake\Validation\Validator $validator): Cake\Validation\Validator

Returns the default validator object. Subclasses can override this function to add a default validation set to the validator object.

Parameters

Cake\Validation\Validator $validator: The validator that can be modified to add some rules to it.

Returns

Cake\Validation\Validator

validationMethodExists() ¶ protected

validationMethodExists(string $name): bool

Checks if validation method exists.

Parameters

string $name

Returns

bool

validator() ¶ public

validator(string|null $name = null, Cake\Validation\Validator|null $validator = null): Cake\Validation\Validator

There are two different ways of creating and naming validation sets: by creating a new method inside your own Table subclass, or by building the validator object yourself and storing it using this method.

For example, if you wish to create a validation set called 'forSubscription', you will need to create a method in your Table subclass as follows:

public function validationForSubscription($validator)
{
 return $validator
 ->add('email', 'valid-email', ['rule' => 'email'])
 ->add('password', 'valid', ['rule' => 'notBlank'])
 ->requirePresence('username');
}

Otherwise, you can build the object by yourself and store it in the Table object:

$validator = new \Cake\Validation\Validator($table);
$validator
 ->add('email', 'valid-email', ['rule' => 'email'])
 ->add('password', 'valid', ['rule' => 'notBlank'])
 ->allowEmpty('bio');
$table->setValidator('forSubscription', $validator);

You can implement the method in validationDefault in your Table subclass should you wish to have a validation set that applies in cases where no other set is specified.

Parameters

string|null $name optional: the name of the validation set to return
Cake\Validation\Validator|null $validator optional: The validator instance to store, use null to get a validator.

Returns

Cake\Validation\Validator

Throws

RuntimeException

Cake\Validation\Validator[]
