在Codeigniter 3中上传图像文件将返回错误500

Question

所以我试图在数据库中插入并上传文件。但是当我尝试提交时，它会返回服务器错误。

相同的代码正在处理我的其他项目，但它正在使用CI2，我检查了.htaccess及其所有相同的

  

localhost页面无效

     

localhost目前无法处理此请求。

     

HTTP ERROR 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回显配置数组并且没有错误但是当我试图取消注释到这部分时，错误显示。< / p>

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();
        }
    }
}

模型

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());
    }
}
