如何使用$criteria->compare()或$criteria->addCondition()

在 yii 上搜索多个列

我有一个名为product的表，在这个表中我有多个列，例如：＆＃34; productId，name，description ...＆＃34; 我需要我的用户能够在多个列中搜索 $criteria->compare('name' AND 'id' And '','' ,$search,true);但这永远不会奏效！只有一列的工作方式如下： $ criteria-＆gt; addCondition（＆＃34; name LIKE＆＃39;％$ search％＆＃39;＆＃34;）; 或$ criteria-＆gt;比较（＆＃39; productId＆＃39;，$ search，true）;

我的搜索表单：

＆＃13;

<div class="search-bar col-md-9 col-lg-9 no-hor-padding">
	<form role="form" onSubmit="return dosearch();" class="navbar-form- navbar-left- search-form" style="padding-left: 0;"
		action="<?php echo Yii::app()->createAbsoluteUrl('/'); ?>" method="get">
		<input type="text" maxlength="30" placeholder="<?php echo Yii::t('app','Search products'); ?>" class="search-icon form-control input-search <?php echo !empty(Yii::app()->user->id) ? "" : "sign" ?>" name="search"></input>
	</form>		  
</div>

＆＃13;

我的功能或控制器：

if(!empty($search)) {
    //$criteria->addCondition("name LIKE '%$search%'");
    $criteria->compare('name',$search,true);

    $searchCriteria = clone $criteria;
    $searchproducts = Products::model()->find($searchCriteria);
    if(empty($searchproducts)){
        $catrest = 1;
        $location = 1;
    }
}

Products :: model（）参考产品表以下是表＆＃34; hts_products＆＃34;。：

的搜索函数表单模型类

＆＃13;

public function search()
	{
		// @todo Please modify the following code to remove attributes that should not be searched.

		$criteria=new CDbCriteria;

		$criteria->compare('productId',$this->productId);
		$criteria->compare('userId',$this->userId);
		$criteria->compare('name',$this->name,true);
		$criteria->compare('price',$this->price);
		$criteria->compare('quantity',$this->quantity);
		$criteria->compare('sizeOptions',$this->sizeOptions,true);
		$criteria->compare('productCondition',$this->productCondition,true);
		$criteria->compare("from_unixtime(`createdDate`, '%d-%m-%Y')",$this->createdDate,true);
		//if(!empty($this->createdDate))
		//$criteria->condition = "from_unixtime(`createdDate`, '%d-%m-%Y') = '$this->createdDate'";
		//else
		//$criteria->compare('createdDate',$this->createdDate);
		/* $criteria->compare('likeCount',$this->likeCount);
		$criteria->compare('commentCount',$this->commentCount); */
		$criteria->compare('chatAndBuy',$this->chatAndBuy);
		$criteria->compare('exchangeToBuy',$this->exchangeToBuy);
		$criteria->compare('instantBuy',$this->instantBuy);
		$criteria->compare('paypalid',$this->paypalid,true);
		// $criteria->order = 'productId DESC';
		return new CActiveDataProvider($this, array(
		'criteria'=>$criteria,
		'pagination'=>array(
              'pageSize'=>10,
		),
		'sort'=>array(
               'defaultOrder'=>'productId DESC',
		)

		));
	}

对于多列搜索，使用变量和用户输入，compare()可能是最佳选择。取自official Yii 1.1.x docs：

compare（）方法使用新的比较附加到condition属性表达。比较是通过比较列与使用一些比较运算符给定值。请注意，将从值中删除任何周围的空格比较之前。当值为空时，没有比较表达式将被添加到搜索条件中。

实施例。在模型Invoices中，在提交之前，在搜索表单中包含空值：

public function search() {
        $criteria = new CDbCriteria;
        $criteria->compare('invoice_number', $this->invoice_number);
        $criteria->compare('city_id', $this->city_id);
        $criteria->compare('state', $this->state);

        return new CActiveDataProvider($this, array(
            'criteria' => $criteria,
        ));
}

它将输出类似于：

的内容

SELECT * FROM `invoices`

提交后，在搜索表单中填写所有值：

SELECT * FROM `invoices` 
WHERE ( invoice_number = :ycp1 AND city_id = :ycp2 AND state = :ycp3)

仅填写invoice_number并从表单中提交。 city_id和state为空：

SELECT * FROM `invoices` 
WHERE ( invoice_number = :ycp1 )

您可以查看所有compare() method documentation以根据需要自定义它。

我建议您使用compare()来匹配数字等确切值。

对于使用LIKE或不精确/近似值的多列搜索，建议您使用addSearchCondition()。

示例：

public function search() {
        $criteria = new CDbCriteria;
        $criteria->compare('invoice_number', $this->invoice_number);
        $criteria->compare('city_id', $this->city_id);
        $criteria->compare('state', $this->state);
        $criteria->addSearchCondition('customer_name', $this->customer_name);

        return new CActiveDataProvider($this, array(
            'criteria' => $criteria,
        ));
}

它将输出类似于：

的内容

SELECT * FROM `invoices` 
WHERE ( invoice_number = :ycp1 AND city_id = :ycp2 AND state = :ycp3 AND customer_name LIKE :ycp4 )

如果您需要使用compare()的更多代码示例以及CDbCriteria you can see this nice article中的其他方法。
