Yii2 validator for complex array structures
Validator for array attributes, unlike builtin "each" validator, that support only one rule, this validator can
- validate multiple array attributes and even nested data structures
- All keys that should be present in array must be described, for optional keys default value should be set
- When input array not contains key defined in rules, this key added automatically with null value
- When input array contains key not defined in rules, "unexpected item" error will be defined
Installation
composer require insolita/yii2-array-structure-validator
Usage
For a simple array with known keys like ['id'=>1, 'name'=>'John Doe']
;
public function rules() { return [ //... ['simpleArray', ArrayStructureValidator::class, 'rules'=>[ 'id'=>[['required'], ['integer','min'=>0]], 'name'=>[['required'], ['string', 'max'=>100]], 'sex'=>[['default', 'value'=>'male'], ['in','range'=>['male','female']] ]] ], ]; }
For multidimensional arrays like
[ ['id'=>1, 'name'=>'John Doe'], ['id'=>2, 'name'=>'Jane Doe','sex'=>'female'], ... ]
set each = true
public function rules() { return [ //... [['multiArray', 'some', 'attrs'], 'required'], ['multiArray', ArrayStructureValidator::class, 'each'=>true, 'rules'=>[ 'id'=>[['required'], ['integer','min'=>0]], 'name'=>[['required'], ['string', 'max'=>100]], 'sex'=>[['default', 'value'=>'male'], ['in','range'=>['male','female']] ]] ] ]; }
For nested structures like
[
'user'=>['id'=>1, 'name'=>'John Doe'],
'coords'=>[['x'=>1, 'y'=>2],['x'=>3,'y'=>4]]
]
public function rules() { return [ //... ['complexArray', ArrayStructureValidator::class, 'rules'=>[ 'user'=>[[ArrayStructureValidator::class, 'rules'=>[ 'id'=>[['required'], ['integer','min'=>0]], 'name'=>[['required'], ['string', 'max'=>100]], ]]], 'coords'=>[[ArrayStructureValidator::class, 'each'=>true, 'rules'=>[ 'x'=>[['required'], ['integer','min'=>0]], 'y'=>[['required'], ['integer','min'=>0]], ], 'min'=>1, 'max'=>5]], ], 'min'=>2, 'max'=>2] ]; }
Model scenarios supported
public function rules() { return [ //... ['conditional', ArrayStructureValidator::class, 'rules'=>[ 'a'=>[['integer','min'=>0]], //will be checked on any scenario 'b'=>[ ['default', 'value'=>1, 'on'=>['create']], ['integer', 'max'=>10, 'except'=>['create']], ['required', 'on'=>['update']], ['integer', 'max'=>1000, 'on'=>['update']], ] ] ] ]; }
Closure and Inline validators supported, but with signature different from default
Inline method in model class
public function rules() { return [ ['array', ArrayStructureValidator::class, 'rules'=>[ 'item'=>[['required'], ['customValidator']] ]] ]; } public function customValidator($attribute, $model, $index, $baseModel, $baseAttribute){ /** * $model - Dynamic model with attributes equals value data, or value row, if used with each=>true * $attribute - current keyName * $index - current array index for multidimensional arrays, or null * $baseModel - instance of initial model, where validator was attached * $baseAttribute - name of initial attributed, where validator was attached * access to validated value - $model->$attribute * access to whole validated array $baseModel->$baseAttribute * $model->addError($attribute, '[{index}][{attribute}] Error message', ['index'=>$index]); */ }
When conditions supported (But not whenClient!)
public function rules() { return [ ['conditional', ArrayStructureValidator::class, 'rules'=>[ 'x'=>[['safe']], 'y'=>[ ['default', 'value'=>1, 'when'=>fn(DynamicModel $model) => $model->x < 10], [ 'default', 'value'=>5, 'when'=>function($model, $attribute, $index, $baseModel, $baseAttribute){ return count($baseModel->$baseAttribute) > 5; }], ] ]] ]; }
Note:
Database related validators (exists, unique) not covered by tests yet and not supported
