Search Yii使用条件搜索并添加参数

我有一个表格，我想在我的数据库中搜索。我用所有参数创建对象，但有一个问题。当写入一个文本字段时，搜索工作正常，查询运行正常。当写入两个或多个文本字段时，参数不起作用，并且查询执行失败：

在哪里 （（（id_reservation=：id_reservation）和（start=：start））和（end=：end））和 （fkCustomer.first_name=：first_name））

params不能代替

    $criteria=new CDbCriteria;
    $criteria->with =array('fkCustomer');
    if(!empty($start))
    {
        $criteria->addCondition('start=:start');
        $criteria->params=array(':start'=>$start);
    }
    if(!empty($end))
    {

        $criteria->addCondition('end=:end');
        $criteria->params=array(':end'=>$end);
    }
    if(!empty($merge->customer_name))
    {

        $criteria->addCondition('fkCustomer.first_name=:first_name');
        $criteria->params=array(':first_name'=>$merge->customer_name);
    }
    if(!empty($merge->customer_surname))
    {

        $criteria->addCondition('fkCustomer.last_name=:last_name');
        $criteria->params=array(':last_name'=>$merge->customer_surname);
    }
    if(!empty($merge->customer_email))
    {

        $criteria->addCondition('fkCustomer.email=:email');
        $criteria->params=array(':email'=>$merge->customer_email);
    }
    $criteria->limit = 100;

这是因为在每个

if

块中，都替换

params

数组。在

if

块中构建一个数组，然后将其添加到块外最后一行的

$criteria->params

例如：

$criteria=new CDbCriteria;
$criteria->with =array('fkCustomer');
$my_params = array();

if(!empty($end))
{
    $criteria->addCondition('end=:end');
    $my_params['end'] = $end;
}

if(!empty($merge->customer_name))
{
    $criteria->addCondition('fkCustomer.first_name=:first_name');
    $my_params['first_name'] = $merge->customer_name;
}

// other ifs ..

//then
$criteria->limit = 100;
$criteria->params = $my_params;

另外，如果我没记错的话，您不需要在

params

数组中写入“：end”和“：first_name”，它将在没有冒号的情况下工作。

您还有以下替代方法

$criteria=new CDbCriteria;
$criteria->with = 'fkCustomer';

if(!empty($end))
{
    $criteria->compare('end', $end);
}

if(!empty($merge->customer_name))
{
    $criteria->compare('fkCustomer.first_name', $merge->customer_name);
}

// The following conditions ..

// Limit:
$criteria->limit = 100;

---

您还可以选择以下选项

$criteria=new CDbCriteria;
$criteria->with = 'fkCustomer';

if(!empty($end))
{
    $criteria->compare('end', $end);
}

if(!empty($merge->customer_name))
{
    $criteria->compare('fkCustomer.first_name', $merge->customer_name);
}

// The following conditions ..

// Limit:
$criteria->limit = 100;

您好，我想这与我以前遇到的params变量的问题相同，为了避免这个问题，我使用了CMap:：mergeArray函数

之所以会发生这种情况，是因为每次条件通过变量时都会覆盖该变量

这是避免它的语法，它是一个例子

$criteria=new CDBCriteria;
$criteria->addBetweenCondition("Date",$datestart,$dateend);
$criteria->addCondition("Type=:type");
//$criteria->params=array(":type"=>"1"); //This is wrong, overwrites addBetweenCondition params
$criteria->params=CMap::mergeArray($criteria->params,array(
    ":type"=>"1",
)); //This is ok, mantain all parameters in the params var
$query=Model::findAll($criteria);
