验证两个字段不应该彼此相等 yii2

Question

我有一个可以创建足球比赛的表格。有 3 个字段 home team（下拉列表，用户在其中选择一个团队），away team（也是下拉列表）和分数字段。所以 <option> 标签值等于 team_id。

例如，我可以选择主队juventus、客队milan和得分2:2。问题是，我应该验证主队是否不等于客队，所以用户不应该为自己创建足球比赛队，例如 juventus vs juventus。我应该如何验证这些字段（home_team、away_team）彼此不相等？

规则方法

 public function rules()
 {
    return [
        [['score'], 'required'],
        ['home_team_id', 'required', 'message' => 'Please choose a home team'],
        ['away_team_id', 'required', 'message' => 'Please choose a away team'],
        ['score', 'match', 'pattern' => '/^\d{1,2}(:\d{1,2})?$/'],
        ['home_team_id', 'compare', 'compareValue' => 'away_team_id', 'operator' => '!=', 'message' => 'Please choose a different teams'],
        [['away_team_id'], 'exist', 'skipOnError' => true, 'targetClass' => Team::className(), 'targetAttribute' => ['away_team_id' => 'id']],
        [['home_team_id'], 'exist', 'skipOnError' => true, 'targetClass' => Team::className(), 'targetAttribute' => ['home_team_id' => 'id']],
        [['round_id'], 'exist', 'skipOnError' => true, 'targetClass' => Round::className(), 'targetAttribute' => ['round_id' => 'id']],
    ];
  }

我的表格

<?php $form = ActiveForm::begin(); ?>

<?= $form->field($model, 'home_team_id')->dropDownList($items, $params)->label('Home Team');?>

<?= $form->field($model, 'away_team_id')->dropDownList($items, $params)->label('Away Team');?>

<div class="hidden">
    <?= $form->field($model, 'round_id')->hiddenInput()->label(''); ?>
</div>

<?= $form->field($model, 'score')->textInput([
    'maxlength' => true,
    'placeholder' => 'seperate goals with colon, for example 2:1'
]) ?>

<div class="form-group">
    <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>

<?php ActiveForm::end(); ?>

$items 数组包含团队（名称和 ID）

Answer 1

只需使用比较验证器：Docs

Answer 2

['home_team_id', 'compare', 'compareAttribute' => 'away_team_id', 'operator' => '!=', 'message' => 'Please choose a different teams'],

将比较值更改为 CompareAttribute
