 * UniqueValidator validates that the attribute value is unique in the specified database table.
 *
 * UniqueValidator checks if the value being validated is unique in the table column specified by
 * the ActiveRecord class [[targetClass]] and the attribute [[targetAttribute]].
 *
 * The following are examples of validation rules using this validator:
 *
 * ```php
 * // a1 needs to be unique
 * ['a1', 'unique']
 * // a1 needs to be unique, but column a2 will be used to check the uniqueness of the a1 value
 * ['a1', 'unique', 'targetAttribute' => 'a2']
 * // a1 and a2 need to be unique together, and they both will receive error message
 * [['a1', 'a2'], 'unique', 'targetAttribute' => ['a1', 'a2']]
 * // a1 and a2 need to be unique together, only a1 will receive error message
 * ['a1', 'unique', 'targetAttribute' => ['a1', 'a2']]
 * // a1 needs to be unique by checking the uniqueness of both a2 and a3 (using a1 value)
 * ['a1', 'unique', 'targetAttribute' => ['a2', 'a1' => 'a3']]

		0 ignored issues – show Coding Style Comprehensibility introduced 2017-04-18 10:35 UTC by Report Bug Copy Issue Report `$conditions` was never initialized. Although not strictly required by PHP, it is generally a good practice to add `$conditions = array();` before regardless. Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code. Let’s take a look at an example: foreach ($collection as $item) { $myArray['foo'] = $item->getFoo(); if ($item->hasBar()) { $myArray['bar'] = $item->getBar(); } // do something with $myArray } As you can see in this example, the array `$myArray` is initialized the first time when the foreach loop is entered. You can also see that the value of the `bar` key is only written conditionally; thus, its value might result from a previous iteration. This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization `$myArray = array()` either outside or inside the foreach loop.

		0 ignored issues – show Documentation introduced 2016-12-15 09:48 UTC by Report Bug Copy Issue Report `$targetClass` is of type `object<yii\db\ActiveRecordInterface>`, but the function expects a `string`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
