Question

我已经使用CodeIgniter构建了一个页面，它具有搜索功能和数据表。每当我单击搜索按钮时，数据表将根据提交的参数进行相应更改。但它没有像我预期的那样工作。

这是我的模特

public function ocsmodel($biostype=null, $manufacture=null)
{
    // Loading second db and running query.
    if ($biostype==null and $manufacture == Null) {
        $this->ocs = $this->load->database('ocsweb', TRUE);
        return $this->ocs->select('ocslist.*')
                         ->from('ocslist')
                         ->limit(100)
                         ->get();            
    }
    else {
        if ($manufacture == "") {

        }
        else {
             $this->ocs = $this->load->database('ocsweb', TRUE);
            return $this->ocs->select('ocslist.*')
                             ->from('ocslist')
                             ->where('bios_type',$biostype)
                             ->where('smanufature',$manufacture)
                             ->limit(100)
                             ->get();   
        }

    }

}

这是我的控制器

public function ocslist()
{

    $manufactur ="";
    $biostype ="";


    if (isset($_POST['bios_type'])){
        $biostype = $this->input->post('bios_type');
        if (isset($_POST['manufacture'])){
            $manufactur = $this->input->post('manufacture');
        }

        $data['ocs'] = $this->assetmodel->ocsmodel()->result_array();

    } 
    else {
        $data['ocs'] = $this->assetmodel->ocsmodel($biostype,$manufactur)->result_array();  
    }


    $data['ocstype'] = $this->assetmodel->getocstype()->result_array();
    $data['ocsmanu'] = $this->assetmodel->getocsmanu()->result_array();
    $data['content'] = 'master/ocs_list';
    $this->load->view('template', $data, FALSE);    
}

这是我的观点

如何将控制器更改为

public function ocslist()
{

    $data['ocs'] = $this->assetmodel->ocsmodel($this->input->post('bios_type'), $this->input->post('manufacture'))->result_array();
    $data['ocstype'] = $this->assetmodel->getocstype()->result_array();
    $data['ocsmanu'] = $this->assetmodel->getocsmanu()->result_array();
    $data['content'] = 'master/ocs_list';
    $this->load->view('template', $data, FALSE);    
}

因为CI将所有POST数据设置为null（如果它们不存在）

根据您的观点尝试将按钮类型更改为类似

的类型

<button type="submit" class="btn btn-info" name="submit">Search</button>

搜索提交按钮在CodeIgniter中不起作用
