我很可能遗漏了一些非常明显的东西，但我还是有点迷茫。实际的数据库交互似乎是关键。我的意思是，该表是在安装时创建的，但实际上发送信息似乎不起作用，因为无论我输入什么都会触发验证。如果我关闭字段要求，数据库将无法完全接收信息。
从控制器：
类 Admin 扩展 Admin_Controller {
private $show_validation_rules = array(
array(
'field' => 'date',
'label' => 'Date',
'rules' => 'trim|max_length[100]|required'
),
array(
'field' => 'location',
'label' => 'Location',
'rules' => 'trim|max_length[300]'
),
array(
'field' => 'support',
'label' => 'Support',
'rules' => 'trim|required'
)
);
public function __construct()
{
parent::__construct();
$this->load->model('shows_m');
$this->load->library('form_validation');

$this->load->helper('html');
$this->template->set_partial('shortcuts', 'admin/partials/shortcuts');
}
public function index()
{
$view_data = array();
$view_data['shows'] = $this->shows_m->get_all();
$this->template->build('admin/index', $view_data);
}
public function create()
{
$shows = $this->shows_m->get_all();
$this->form_validation->set_rules($this->show_validation_rules);
if ( $this->form_validation->run() )
{
if ($this->shows_m->insert_show($this->input->post()))
{
$this->session->set_flashdata('success', lang('shows.create_success'));
redirect('admin/shows/index');
} else {
$this->session->set_flashdata('error', lang('shows.create_error'));
redirect('admin/shows/create');
}
}
foreach($this->show_validation_rules as $rule)
{
$shows[$rule['field']] = $this->input->post($rule['field']);
}
$view_data = array(
'shows' => $shows
);
$this->template->build('admin/create', $view_data);
}
public function edit($id)
{
$this->form_validation->set_rules($this->show_validation_rules);
$show = $this->shows_m->get($id);
if ( empty($show) )
{
$this->session->set_flashdata('error', lang('shows.exists_error'));
redirect('admin/shows');
}
if ( $this->form_validation->run() )

redirect('admin/shows/edit/' . $id);
}
else
{
$this->session->set_flashdata('error', lang('shows.update_error'));
redirect('admin/shows/edit/' . $id);
}
}
}
foreach($this->show_validation_rules as $rule)
{
if ($this->input->post($rule['field']))
{
$show[$rule['field']] = $this->input->post($rule['field']);
}
}
$view_data = array(
'shows' => $show
);
$this->template->build('admin/edit', $view_data);
}
public function delete($id = NULL)
{
$id_array = array();
if ( $this->input->post() )
{
$id_array = $this->input->post()['action_to'];
}
else
{
if ( $id !== NULL )
{
$id_array[0] = $id;
}
}
if ( empty($id_array) )
{
$this->session->set_flashdata('error', lang('shows.id_error'));
redirect('admin/shows');
}
foreach ( $id_array as $id)
{
$show = $this->shows_m->get($id);
if ( !empty($show) )
{
if ( $this->shows_m->delete($id) == FALSE )
{
$this->session->set_flashdata('error', lang('shows.delete_error'));
redirect('admin/shows');
}
}
}
$this->session->set_flashdata('success', lang('shows.delete_success'));
redirect('admin/shows');
}
}
来自 details.php 文件
public function install()
{
$this->dbforge->drop_table('shows');
$shows = "
CREATE TABLE ".$this->db->dbprefix('shows')." (
`id` int(11) NOT NULL AUTO_INCREMENT,
`date` varchar(100) NOT NULL,
`location` varchar(300) NOT NULL,
`support` text,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
";
if($this->db->query($shows))
{
return TRUE;
}
}
简而言之，该模块的目的是通过将模块生成的标签插入站点上的相关页面来输出演出日期、位置和任何支撑带和其他信息。
我倾向于认为它应该很简单，而且我遗漏了一些明显的东西，但谁知道呢。如果我是，请随意对我大喊大叫，我会很感激的。
