Question

一次插入多行我已經通過http://www.yiiframework.com/doc/guide/1.1/en/form.table

走後，我不明白這是什麼意思：

$items=$this->getItemsToUpdate(); 

這是什麼$this->getItemsToUpdate()功能？

我試圖一次插入動態行。我用jquery創建數據，但我不知道如何將它們插入到數據庫中。

Answer 1

如果您不受限於使用Active Records，則可以使用DAO執行適當的SQL插入語句以插入多行。提前

Insert multiple records into MySQL with a single query

一旦你有你的INSERT語句作爲一個字符串（可以動態使用的情況下，一個循環來構建你不知道有多少行：你可以在這裏找到這樣的語句的例子你需要插入），你可以像這樣執行它：

$sql = 'INSERT statement goes here'; 
$connection = Yii::app() -> db; 
$command = $connection -> createCommand($sql); 
$command -> execute(); 

Answer 2

我遇到了同樣的問題。

據我所知Yii沒有插入多行的默認函數。

/** 
* Creates and executes an INSERT SQL statement for several rows. 
* @param string $table the table that new rows will be inserted into. 
* @param array $array_columns the array of column datas array(array(name=>value,...),...) to be inserted into the table. 
* @return integer number of rows affected by the execution. 
*/ 
public function insertSeveral($table, $array_columns) 
{ 
    $sql = ''; 
    $params = array(); 
    $i = 0; 
    foreach ($array_columns as $columns) { 
     $names = array(); 
     $placeholders = array(); 
     foreach ($columns as $name => $value) { 
      if (!$i) { 
       $names[] = $this->_connection->quoteColumnName($name); 
      } 
      if ($value instanceof CDbExpression) { 
       $placeholders[] = $value->expression; 
       foreach ($value->params as $n => $v) 
        $params[$n] = $v; 
      } else { 
       $placeholders[] = ':' . $name . $i; 
       $params[':' . $name . $i] = $value; 
      } 
     } 
     if (!$i) { 
      $sql = 'INSERT INTO ' . $this->_connection->quoteTableName($table) 
       . ' (' . implode(', ', $names) . ') VALUES (' 
       . implode(', ', $placeholders) . ')'; 
     } else { 
      $sql .= ',(' . implode(', ', $placeholders) . ')'; 
     } 
     $i++; 
    } 
    return $this->setText($sql)->execute($params); 
} 

用法：

$rows = array(
      array('id' => 1, 'name' => 'John'), 
      array('id' => 2, 'name' => 'Mark') 
); 
$command = Yii::app()->db->createCommand(); 
$command->insertSeveral('users', $rows);

更新

由於

所以我在CdbCommand類（框架/ DB/CDbCommand.php）創建一個Nabi K.A.Z.提到它真的好多了不要觸摸框架的源代碼。 在我的項目中，我實際上創建了MyCDbCommand類（它擴展了CDbCommand），並且創建了MyCDBConnection（擴展了CDbConnection）。

MyCDbCommand（擴展CDbCommand）：

class MyCDbCommand extends CDbCommand 
{ 
    protected $_connection; 

    public function __construct(CDbConnection $connection, $query = null) 
    { 
     $this->_connection = $connection; 
     parent::__construct($connection, $query); 
    } 

    /** 
    * Creates and executes an INSERT SQL statement for several rows. 
    * @param string $table the table that new rows will be inserted into. 
    * @param array $array_columns the array of column datas array(array(name=>value,...),...) to be inserted into the table. 
    * @return integer number of rows affected by the execution. 
    */ 
    public function insertSeveral($table, $array_columns) 
    { 
     $sql = ''; 
     $params = array(); 
     $i  = 0; 
     foreach ($array_columns as $columns) { 
      $names  = array(); 
      $placeholders = array(); 
      foreach ($columns as $name => $value) { 
       if (!$i) { 
        $names[] = $this->_connection->quoteColumnName($name); 
       } 
       if ($value instanceof CDbExpression) { 
        $placeholders[] = $value->expression; 
        foreach ($value->params as $n => $v) { 
         $params[$n] = $v; 
        } 
       } else { 
        $placeholders[]   = ':' . $name . $i; 
        $params[':' . $name . $i] = $value; 
       } 
      } 
      if (!$i) { 
       $sql = 'INSERT INTO ' . $this->_connection->quoteTableName($table) 
        . ' (' . implode(', ', $names) . ') VALUES (' 
        . implode(', ', $placeholders) . ')'; 
      } else { 
       $sql .= ',(' . implode(', ', $placeholders) . ')'; 
      } 
      $i++; 
     } 
     return !empty($sql) ? $this->setText($sql)->execute($params) : 0; 
    } 

} 

MyCDBConnection（擴展CDbConnection和使用MyCDbCommand）：

class MyCDbConnection extends CDbConnection 
{ 

    public function createCommand($query = null) 
    { 
     $this->setActive(true); 
     return new MyCDbCommand($this, $query); 
    } 
} 

然後我改變配置文件（/保護/配置/ main.php）。 我已經改變了CDbConnection到MyCDbConnection有：

... 
'components'=>array(
    ... 
    'db' => array(
     'connectionString' => 'mysql:host=localhost;dbname=dname', 
     'username'   => 'user', 
     'password'   => 'password', 
     'charset'   => 'utf8', 
     'class'   => 'MyCDbConnection', // Change default CDbConnection class to MyCDbConnection 
    ), 
    ... 
    ) 
... 

在這裏你去。我們沒有觸及核心框架，而是可以像以前一樣使用它。

Answer 3

以上代碼從Pigalev Pavel是偉大的。

但是這需要修改核心框架，這是不好的！

所以，我寫了一個獨立的類。

將此代碼放入components文件夾下的GeneralRepository.php文件名。

<?php 
class GeneralRepository 
{ 
    /** 
    * Creates and executes an INSERT SQL statement for several rows. 
    * 
    * Usage: 
    * $rows = array(
    *  array('id' => 1, 'name' => 'John'), 
    *  array('id' => 2, 'name' => 'Mark') 
    *); 
    * GeneralRepository::insertSeveral(User::model()->tableName(), $rows); 
    * 
    * @param string $table the table that new rows will be inserted into. 
    * @param array $array_columns the array of column datas array(array(name=>value,...),...) to be inserted into the table. 
    * @return integer number of rows affected by the execution. 
    */ 
    public static function insertSeveral($table, $array_columns) 
    { 
     $connection = Yii::app()->db; 
     $sql = ''; 
     $params = array(); 
     $i = 0; 
     foreach ($array_columns as $columns) { 
      $names = array(); 
      $placeholders = array(); 
      foreach ($columns as $name => $value) { 
       if (!$i) { 
        $names[] = $connection->quoteColumnName($name); 
       } 
       if ($value instanceof CDbExpression) { 
        $placeholders[] = $value->expression; 
        foreach ($value->params as $n => $v) 
         $params[$n] = $v; 
       } else { 
        $placeholders[] = ':' . $name . $i; 
        $params[':' . $name . $i] = $value; 
       } 
      } 
      if (!$i) { 
       $sql = 'INSERT INTO ' . $connection->quoteTableName($table) 
       . ' (' . implode(', ', $names) . ') VALUES (' 
       . implode(', ', $placeholders) . ')'; 
      } else { 
       $sql .= ',(' . implode(', ', $placeholders) . ')'; 
      } 
      $i++; 
     } 
     $command = Yii::app()->db->createCommand($sql); 
     return $command->execute($params); 
    } 
} 

和使用的任何地方：

$rows = array(
    array('id' => 1, 'name' => 'John'), 
    array('id' => 2, 'name' => 'Mark') 
); 
GeneralRepository::insertSeveral(User::model()->tableName(), $rows); 

Answer 4

Yii的支持添加多個記錄。

使用此....

$alertStatus[] = array(
         'db_field_name1' => $value1, 
         'db_field_name1' => $value2, 
         'created_on' => new CDbExpression('NOW()'), 
         'modified_on' => new CDbExpression('NOW()') 
        ); 
$connection = Yii::app()->db->getSchema()->getCommandBuilder(); 
$command = $connection->createMultipleInsertCommand('table_name', $alertStatus); 
      $command->execute(); 

$ alertStatus數組應該包含所有數據庫
