如何使用codeigniter将值数组发送到数据库

<?php
class MyModel extends CI_Model {
    public function insertData($data) {
        $this->db->insert('table_name', $data);
        return $this->db->insert_id();
    }
}
?>

<?php
class MyController extends CI_Controller {
    public function __construct() {
        parent::__construct();
        $this->load->model('MyModel');
        $this->load->database();
    }

    public function insertData() {
        $data = array(
            'field1' => 'value1',
            'field2' => 'value2',
            // 添加更多字段和值
        );

        $insertId = $this->MyModel->insertData($data);
        echo "Data inserted with ID: " . $insertId;
    }
}
?>
