我正在致力于codeigniter应用程序，以允许用户添加编辑和修改数据库。动态地在codeigniter中添加数据库
我想通过循环重复此代码：
$db['db1']['hostname'] = 'localhost';
$db['db1']['username'] = 'ts4l_wp13';
$db['db1']['password'] = 'O&3D6c(0zD70.^9';
$db['db1']['database'] = 'ts4l_wp13';
$db['db1']['dbdriver'] = 'mysql';
$db['db1']['dbprefix'] = '';
$db['db1']['pconnect'] = FALSE;
$db['db1']['db_debug'] = TRUE;
$db['db1']['cache_on'] = FALSE;
$db['db1']['cachedir'] = '';
$db['db1']['char_set'] = 'utf8';
$db['db1']['dbcollat'] = 'utf8_general_ci';
$db['db1']['swap_pre'] = '';
$db['db1']['autoinit'] = TRUE;
$db['db1']['stricton'] = FALSE;
我这样做：
@$get_data = mysql_query("SELECT * FROM `database_name`");
while($getdata = mysql_fetch_assoc($get_data)){
$id='db'.$getdata['id'];
$iid="$id";
$db["$iid"]['hostname'] = 'localhost';
$db["$iid"]['username'] = $getdata['username'];
$db["$iid"]['password'] = $getdata['password'];
$db["$iid"]['database'] = $getdata['name'];
$db["$iid"]['dbdriver'] = 'mysql';
$db["$iid"]['dbprefix'] = '';
$db["$iid"]['pconnect'] = FALSE;
$db["$iid"]['db_debug'] = TRUE;
$db["$iid"]['cache_on'] = FALSE;
$db["$iid"]['cachedir'] = '';
$db["$iid"]['char_set'] = 'utf8';
$db["$iid"]['dbcollat'] = 'utf8_general_ci';
$db["$iid"]['swap_pre'] = '';
$db["$iid"]['autoinit'] = TRUE;
$db["$iid"]['stricton'] = FALSE;
}
和该块。
// Loading db and running query.
$CI = &get_instance();
$this->db1 = $CI->load->database('db1', TRUE);
$this->db1->set($data);
$this->db1->insert($this->_table_name);
$id=$this->db1->insert_id();
我这样做：“你已经指定了一个无效的数据库连接组”
$this->load->model('mdb_m');
$dbms =$this->mdb_m->get();
if (count($dbms)) {
foreach ($dbms as $dbm) {
$mid=$dbm->id;
$dbc='db'.$mid;
$CI = &get_instance();
$this->db.$mid = $CI->load->database("$dbc" , TRUE);
$this->db.$mid->set($data);
$this->db.$mid->insert($this->_table_name);
}
}
但只在阵列中的第一个数据库中插入，然后停止和retrive这个错误
