php - yii 中的 findAll()

Question

电子邮件存档表：

id email_id to from
1  101      uk  msm
2  102      uu  avc
3  101      rk  uk
4  103      xyz abc
5  104      xyz poi
6  104      abc xyz
7  101      xyz abc

现在在 Yii 中，我想记录下 email_id=101 我正在使用下面的代码，但它不起作用。

$id =101;
$criteria = new CDbCriteria();
$criteria->addCondition("email_id < :email_id");
$comments = EmailArchive::model()->findAll($criteria, array(':email_id' => $id,));

Answer 1

尝试：

$id =101;
$comments = EmailArchive::model()->findAll(
array("condition"=>"email_id =  $id","order"=>"id"));

或者

$id =101;
$criteria = new CDbCriteria();
$criteria->addCondition("email_id=:email_id");
$criteria->params = array(':email_id' => $id);
$comments = EmailArchive::model()->findAll($criteria);

或者

$Criteria = new CDbCriteria();
$Criteria->condition = "email_id = $id";
$Products = Product::model()->findAll($Criteria);

Answer 2

如果你使用findAll()，我建议你使用这个：

$data_email = EmailArchive::model()->findAll(
                  array(
                      'condition' => 'email_id = :email_id',
                      'params'    => array(':email_id' => $id)
                  )
              );

Answer 3

Just to add some alternate, you could do like this also:

$id =101;
$criteria = new CDbCriteria();
$criteria->condition = "email_id =:email_id";
$criteria->params = array(':email_id' => $id);
$comments = EmailArchive::model()->findAll($criteria);

Answer 4

在 yii 中使用 findall 的另一种简单方法

$id =101; 
$comments = EmailArchive::model()->findAll(array("condition"=>"':email_id'=$id"));
foreach($comments as $comments_1) 
{ 
echo  "email:".$comments_1['email_id'];
}

Answer 5

这是您最安全的方法：

$id =101;
//$user_id=25;
$criteria=new CDbCriteria;
$criteria->condition="email_id < :email_id";
//$criteria->addCondition("user_id=:user_id");
$criteria->params=array(
  ':email_id' => $id,
  //':user_id' => $user_id,
);
$comments=EmailArchive::model()->findAll($criteria);

请注意，如果您注释掉注释行，您将获得一种在搜索中添加更多过滤的方法。

在此之后，建议检查是否有任何数据返回，例如：

if (isset($comments)) { // We found some comments, we can sleep well tonight
  // do comments process or whatever
}

Answer 6

如果你使用 $criteria，我推荐使用：

$criteria = new CDbCriteria();
$criteria->compare('email_id', 101);
$comments = EmailArchive::model()->findAll($criteria);

Answer 7

$id = 101;

$sql = 'SELECT * FROM ur_tbl t WHERE t.email_id = '. $id;
$email = Yii::app()->db->createCommand($sql)->queryAll();

var_dump($email);

Answer 8

使用下面的代码。这应该有效。

$comments = EmailArchive::find()->where(['email_id' => $id])->all();
