使用 CodeIgniter 将表单数据插入数据库

Question

这是我遇到的问题，我正在使用 HMVC，到目前为止：

routes.php

$route['create_qso'] = 'qso/create_qso';
$route['insert_qso'] = 'qso/insert_qso';

Qso_model.php 模型

function add_qso($data){

     $data = array(
        'user_id' => $this->input->post('user_id'),
        'date' => $this->input->post('date'),
        'time_in_field' => $this->input->post('time-in-field'),
        'discipline_id' => $this->input->post('discipline'),
        'shift_id' => $this->input->post('shift'),
        'type_id' => $this->input->post('type'),
        'at_risk_category_id' => $this->input->post('at-risk'),
        'at_risk_details' => $this->input->post('at-risk-details'),
        'severity_level_id' => $this->input->post('severity-level'));



    $this->db->insert('qso', $data);}

create_qso.php 查看

public function __construct()

    parent::__construct();
    //Transfers data to model
    $this->load->model('Qso_model'); // load the model

} 

public function index() {  
    //  Quick Page setup is the same as $this->load->view() method used in CI
    $this->quick_page_setup(Settings_model::$db_config['active_theme'], 'main', 'Create QSO', 'create_qso', 'header', 'footer');  

    // Setting values for table coloums

}
public function insert_qso() {

    $this->Qso_model->add_qso();
    $this->load->view('qso/insert_qso');

}
}

当我运行这个时，表单显示很好，我可以输入数据，但是当我提交表单时，我得到了这个：

我不知道如何从表单中将数据插入数据库中的 qso 表中？

Answer 1

您使用的是哪种类型的 HMVC？

首先，这是我的 HMVC 文件夹： HMVC folder

我不需要使用$route['method'] 来配置 url 或查看。我只是在我想加载视图时使用$this->load->view('account',$this->_data);，account.php 将放置在application\modules\account\views中

如果它无法连接并显示错误，可能问题应该是您的 HMVC 源。我在我的项目中使用了bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc 的 HMVC。

第二，在你的 VIEW 文件中，这样写对吗？这里的表格是form_close，不是form_open，对吧？

<div class="text-center">
<?php
    echo form_submit('submit', 'Submit QSO');
    echo form_open('create_qso/insert_qso');
?>
</div>

应该是：

<div class="text-center">
<?php
    echo form_submit('submit', 'Submit QSO');
    echo form_close('create_qso/insert_qso');
?>
</div>
