我正试图从Php 连接到另一个db并更新codeigniter中的一行,php,mysql,codeigniter,codeigniter-2,codeigniter-3,Php,Mysql,Codeigniter,Codeigniter 2,Codeigniter 3,我正试图从admin@something.com添加到$username中的字符串，但正在更新默认数据库，我想连接到新创建的数据库并更新pr_users表中id=1的用户名字段，但无法连接到新创建的数据库并更新该字段 我正在调用一个模型来更新表，即使用$data['applicator\u rows']=$this->mod\u common->add\u new\u user（$email，$userid，$username）不知何故，foreach（$sqls as$statement）后面
admin@something.com$data['applicator\u rows']=$this->mod\u common->add\u new\u user（$email，$userid，$username）不知何故，foreach（$sqls as$statement）后面的语句不起作用，请帮助
以下是我的控制器代码：
控制器：login.php
public function save_userinput()
{
//code goes here
// for example: getting the post values of the form:
$form_data = $this->input->post();
// or just the username:
$username = $this->input->post("username");
$email = $this->input->post("email");
$userid = 1;
$data['applicant_rows'] = $this->mod_common->update_table_with_user_for_the_first_time($email,$userid,$username);
//$data['workspace'] = $this->mod_common->update_admin($email);
// $this->admin_list->manage_package();
$this->load->dbforge();

您的代码易受SQL注入攻击，MD5不用于哈希密码。是否使用用户名为每个用户创建数据库？你到底想用它做什么？！？每个数据库都有一个单独的管理员，这是由于其他一些限制，例如我们在其他代码中依赖于id=1。直接的要求是看看这是否有效，SQL注入和MD5将在稍后处理，这仅用于演示目的
