我正在尝试使用“cornernote/yii2-linkall”和“kartik-v/yii2-widget-select2”来实现多选下拉。我已遵循本指南,它适用于单个多选下拉菜单,所以现在我正在尝试以单一形式实现两个多选下拉菜单,但在这里我被卡住了。当我反复执行更新功能时,它会给出违反完整性约束的错误。

Integrity constraint violation – yii\db\IntegrityException

数据库表如下所示: part(id, name) Industry(id,name)

供应商_to_part(供应商_id,part_id)供应商_to_industry(供应商_id,industry_id)

主表是:- 供应商(id,......)

问题出在 foreach 上。

代替

              foreach ($this->part_ids  as $part_name ){ 
                foreach ($this->industry_ids as $industry_name ){ 
                      $part = Part::getPartByName($part_name);
                     $industry = Industry::getIndustryByName($industry_name);
                   if ($part ||$industry ) {
                    $parts[] = $part;
                    $industries[] = $industry;
                   }
               }
          }

需要使用:

       foreach ($this->production_scope as $part_name ){ 
                $part = Part::getPartByName($part_name);
                if ($part) {
                    $parts[] = $part;
                }
            }
        foreach ($this->target_industry as $industry_name ){ 
                $industry = Industry::getIndustryByName($industry_name);
                if ($industry) {
                    $industries[] = $industry;
                }
            }

在所需的表单字段中使用 $model 变量调用模型名称。前任:

 <?= $form->field($model->industry,'industry_ids')->widget(Select2::className(),['model' => $model->industry, ...
