文件未在codeigniter中上传

问题描述

我知道这个问题可能被问过百万次。我搜索并遵循了上载文件的必要步骤。但是，当我尝试上载文件时，出现了未选择要上载文件的错误。
我的控制器是：

I know this question may have been asked million of times. I searched and followed the required steps for uploading a file.But when i try to upload a file,I get the error of not selecting a file to upload.My controller is:

function save(){
        $this->load->library('upload');
        $config = array();
        $config['upload_path'] = './assets/images/site_data/images/';
        $config['allowed_types'] = 'gif|jpg|png|jpeg';
        $config['max_size']      = '100';
        $config['file_name'] = time();
        $config['overwrite']     = FALSE;
        $this->upload->initialize($config);
        if($this->upload->do_upload()){
                $fInfo = $this->upload->data();
                echo '<pre>';
                print_r($fInfo);
                exit;
            }
        else
            {
            echo  $this->upload->display_errors();
        }
    }

我的观点是：

<form method="post" action="<?php echo base_url()?>books/save" enctype="multipart/form-data">
    <input type="file" name="cover_photo" id="cover_photo">
    <input type="submit" name="save">
</form>

谁能告诉我我的代码有什么问题。如果我做错了，请原谅我。
谢谢。

Can anyone tell me what is wrong with my code.Please forgive me if I have made a mistake.Thanks.

推荐答案

问题是该类希望文件的名称为 userfile ，如文档。

The problem is that the class expects the file to have a name of userfile as seen in the documentation.

要么更改文件输入的名称，要么将要使用的名称添加到 do_upload 调用中。

Either change the name of the file input or add the name you want to use to the do_upload call.

后者的示例：

$field_name = "cover_photo";
$this->upload->do_upload($field_name)
