Question

我在Yii有一个表格。如果我输入预先存在的值，它会给我一个错误。这样工作正常，但是如果我在字段前面添加一些空格，它不会给我一个错误，也不会保存数据，而是像保存数据一样显示数据。当我在末尾添加空格时，它会给我一个自定义错误。请帮我解决这个问题。

我的控制器：

public function actionUpdate($id)
    {
        $model=$this->loadModel($id);
                $user = Yii::app()->db->createCommand()
    ->select('cust_name')
    ->from('mst_customers')
    ->where('cust_id='.$model->host_customer_id)                    
    ->queryAll();
                //print_r($user);
                // Uncomment the following line if AJAX validation is needed
        // $this->performAjaxValidation($model);

        if(isset($_POST['NimsoftHost']))
        {
                      $model->attributes=$_POST['NimsoftHost'];
                      echo $model->host_name;
        $criteria = new CDbCriteria;
                $criteria->condition = "host_name = '$model->host_name'";
                $exist=NimsoftHost::model()->findAll($criteria);
                if($exist)
                {
                    $model->addError(null, "Duplicate values entered");
                }
                else if($model->save())
                        {
                             $this->redirect(array('view','id'=>$model->host_id,'name'=>$user));
                         }
                }

        $this->render('update',array(
            'model'=>$model,
        ));
    }

<?php

        // controller action is handling ajax validation correctly.
        // There is a call to performAjaxValidation() commented in generated controller code.
        // See class documentation of CActiveForm for details on this.
        'enableAjaxValidation' => false

我的模特：

public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
                        array('host_name, host_customer_id, status', 'required'),

昨天我遇到了同样的问题。你的框架是Yii，我的是Laravel，但我认为问题是一样的。这就是我做的 -

Are laravel query results encoded?

如果要在不进行规则检查的模型的情况下提示错误消息，则应调用控制器中的trim（）函数以删除空格。

    if(isset($_POST['NimsoftHost']))
    {
      $model->attributes=$_POST['NimsoftHost'];
      $hostName = trim($model->host_name);

      $exist=NimsoftHost::model()->findByAttributes(array('host_name'=>$hostName));
            if($exist)
            {
                $model->addError(null, "Duplicate values entered");
            }
            else if($model->save())
            {
                $this->redirect(array('view','id'=>$model->host_id,'name'=>$user));
            }
     }

修剪功能不起作用Yii
