Question

我想验证文件上传，条件是文件输入可以上传文件，如果文件输入为空，但如果文件输入与文件设置的类型不匹配则显示错误。如何制作这些错误。如果我使用这个脚本：!$this->upload->do_upload('file')并且我让文件输入为空，肯定会出现错误。

这是我的配置上传：

        $config['upload_path'] = '../../upload/file';
        $config['allowed_types'] = 'pdf';
        $config['file_name'] = 'file_'.time();
        $config['overwrite'] = true;
        $this->upload->initialize($config);

        if(!$this->upload->do_upload('file')){
            $respond['error'] = true;
            $respond['message'] = "Error Upload".$this->upload->display_errors();
        }

Answer 1

您可以添加条件，因此只会验证是否有上传的文件：

<?php

if ( $_FILES && $_FILES['file']['name'] ) 
{
    $config['upload_path'] = '../../upload/file';
    $config['allowed_types'] = 'pdf';
    $config['file_name'] = 'file_'.time();
    $config['overwrite'] = true;
    $this->upload->initialize($config);

    if(!$this->upload->do_upload('file')){
        $respond['error'] = true;
        $respond['message'] = "Error Upload".$this->upload->display_errors();
    }

}

此解决方案将非常适合您

        $config['upload_path']      =   './uploads/;
        $config['allowed_types']    =   'pdf';
        $config['max_size']         =   0;
        $config['max_width']        =   0;
        $config['max_height']       =   0; 

       $config['file_name']        =   round(100,99); //make your file name random

        $this->load->library('upload', $config);
        $this->upload->initialize($config);

        if($this->upload->do_upload('file_name')){
            print $this->upload->data();                    
        }else{
          print $this->upload->display_errors();
        }
