Codeigniter 文件上传和数据库插入 1 种形式

Question

所以我正在尝试插入数据库并上传文件。但是当我尝试提交时，它会返回一个服务器错误。

本地主机页面不工作

localhost 当前无法处理此请求。

HTTP 错误 500

我认为问题出在$this->upload->do_upload('userfile')，因为我试图从这部分注释掉并显示配置数组的回显并且没有错误，但是当我试图取消对此部分的注释时，错误显示。

控制器

public function add_now(){
    $this->load->library('form_validation');
    $this->form_validation->set_rules('Event_Name', 'Event Name', 'trim|strip_tags');
    $this->form_validation->set_rules('Event_Start', 'Start Date', 'trim|strip_tags');
    $this->form_validation->set_rules('Event_End', 'End Date', 'trim|strip_tags');
    $this->form_validation->set_rules('Event_Location', 'Location', 'trim|strip_tags');

    if($this->form_validation->run() == FALSE){
        $this->add();
    }
    else{   
        $query = $this->events_model->do_upload();
        if($query){
            $this->session->set_flashdata('success', 'Successful!');
            $this->index();
        }
        else{
            if(!$this->session->flashdata('upload_error')){
                $this->session->set_flashdata('failed', 'Failed!');
            }
            $this->add();
        }
    }
}

型号

public function do_upload(){
    
    $config['upload_path'] = './resources/images/events_photo/temp/';
    $config['allowed_types'] = 'gif|jpg|jpeg|png';
    $config['file_name'] = uniqid().'.jpeg';
    $config['overwrite'] = TRUE;


    $this->load->library('upload', $config);
    if(!$this->upload->do_upload('userfile')){
        $this->session->set_flashdata('upload_error', $this->upload->display_errors());
    }
}

Answer 1

首先在你的控制器中加载 url helper...

$this->load->helper('url');

然后设置上传文件路径为：

$config['upload_path'] = base_url('resources/images/events_photo/temp/');

试试吧。

那这两个函数呢

$this->add();

$this->success();
