php - PyroCMS/Codeigniter 数据库问题

Question

我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很重要。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，它都会触发验证。如果我关闭字段要求，数据库将无法完全接收信息。

来自 Controller :

Admin 类扩展了 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',

);

public function __construct()

    parent::__construct();

    $this->load->model('shows_m');
    $this->load->library('form_validation');
    $this->lang->load('shows');
    $this->load->helper('html');

    $this->template->set_partial('shortcuts', 'admin/partials/shortcuts');

public function index()

    foreach($this->show_validation_rules as $rule)

    }
    else
    {
        if ( $id !== NULL )

            $id_array[0] = $id;

    foreach ( $id_array as $id)
    {

        $show = $this->shows_m->get($id);

        if ( !empty($show) )
        {

            if ( $this->shows_m->delete($id) == FALSE )

                redirect('admin/shows');
            }
        }
    }

    $this->session->set_flashdata('success', lang('shows.delete_success'));

}

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网站的相关页面来输出演出日期、地点和任何支持乐队以及其他信息。

我倾向于认为它应该非常简单并且我遗漏了一些明显的东西，但谁知道呢。如果是，请随时对我大喊大叫，我将不胜感激。

模型代码

类 Shows_m 扩展了 MY_Model {

public function get_all($limit = NULL)
{
    $this->db->order_by("id", "desc");
    if (isset($limit)){ $this->db->limit($limit); }
    $results = $this->db->get('shows');
    $result = $results->result_array();
    return $result;
}


public function get($id)
{
    $results = $this->db->get_where('shows', array('id' => $id));
    $result = $results->row_array();
    return $result;
}


public function insert_show($input)
{

    $to_insert = array(
        'date' => $input['date'],
        'location' => $input['location'],
        'support' => $input['support']
    );


    if ($this->db->insert('shows',$to_insert))
    {
        return TRUE;
    } else {
        return FALSE;
    }
}


public function update_entry($id, $input)
{
    $new_data = array(
        'date' => $input['date'],
        'location' => $input['location'],
        'support' => $input['support']
    );

    if (isset ($input['delete']) )
    {
        if($this->delete($id))
        {
            return TRUE;
        } else {
            return FALSE;
        }
    } else {

        $this->db->where('id', $id);
        if ($this->db->update('shows', $new_data))
        {
            return TRUE;    
        } else {
            return FALSE;    
        }
    }
}


public function delete($id)
{
    if ($this->db->delete('shows', array('id' => $id)))
    {
        return TRUE;    
    } else {
        return FALSE;

Answer 1

它可能是你在模型中的insert

if ($this->db->insert('shows',$to_insert))
    {
        return TRUE;
    } else {
        return FALSE;
    }

改为尝试:

$this->db->insert('shows',$to_insert);
$query_result = $this->db->insert_id();
if($query_result){
    return TRUE;
}else{
    return FALSE;
}

我不认为 insert 返回任何东西。

无论如何，这听起来不像是验证问题。查询未到达数据库。如果以上不是问题，请尝试仅echo 输出POST 数据；确保它到达模型(确保 HTML 符合预期——输入名称等)。
