一、解决方法:
1 插入数据时,使用CodeIgniterd的Active Record模式的set方法,set()接受可选的第三个参数$escape,如果此参数被设置为FALSE,就可以阻止数据被转义,该参数的默认值是TRUE
2 更新数据时,所有的值会被自动转义,以便生成安全的查询
二、示例:
示例1:
$this->db->set(‘name‘, $name);
$this->db->insert(‘mytable‘);
示例2:
$this->db->set(‘name‘, $name);
$this->db->set(‘age‘, ‘age+1‘);
$this->db->set(‘status‘, $status);
$this->db->insert(‘mytable);
示例3:
$array = array(‘name‘=>$name, ‘title‘=>$title, ‘status‘=>$status);
$this->db->set($array);
$this->db->insert(‘mytable);
示例4:
/*
class Myclass{
var $title = ‘My Title‘, var $content = ‘My Content‘, var $date = ‘My Date‘;
}
*/
$object = new Myclass;
$this->db->set($object);
$this->db->insert(“mytable”);
三、set方法的源码:
/** * The "set" function. Allows key/value pairs to be set for inserting or updating * * @param mixed * @param string * @param boolean * @return object */ public function set($key, $value = ‘‘, $escape = TRUE) { $key = $this->_object_to_array($key); if ( ! is_array($key)) { $key = array($key => $value); } foreach ($key as $k => $v) { if ($escape === FALSE) { $this->ar_set[$this->_protect_identifiers($k)] = $v; } else { $this->ar_set[$this->_protect_identifiers($k, FALSE, TRUE)] = $this->escape($v); } } return $this; }
