Question

我有一个大表单，我只是添加了一个文件输入，以允许用户上传图像。

以下是新的HTML：

<input type="file" name="file_1" />
<input type="text" name="image_description_1" class="text-input"/>

这是新的_submit函数：

if($this->CI->input->post('file_1')){
    $config['overwrite'] = TRUE;
    $config['allowed_types'] = 'jpg|jpeg|gif|png';
    $config['max_size'] = 2000;
    $config['upload_path'] = realpath(APPPATH . '../assets/uploads/avatars');

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

    $image_data = $this->CI->upload->data();

    $image['description'] = $this->CI->input->post('image_description_1');
    $image['user_id'] = $id;
    $image['image'] = $image_data['file_name'];

    $this->CI->db->insert('report_images',$image);

}

说明和user_id已正确提交，但文件已丢失。

我应该做些不同的事吗？不确定出了什么问题。

Answer 1

首先，不要将do_upload()视为理所当然，您必须验证upload：

if ( ! $this->upload->do_upload('file_1'))
{
    // something went wrong, display errors
}   
else
{
    // everything is fine
}

此外，很有可能是你的upload_path，请查看我链接到的文件：

//You'll need a destination folder for your uploaded images. Create a folder at the root of your CodeIgniter installation called uploads and set its file permissions to 777.  
$config['upload_path'] = './uploads/';

因此，您可能需要将设置更改为：

$config['upload_path'] = './assets/uploads/avatars/';

Answer 2

codeigniter期望您的文件输入被命名为userfile，除非您在代码中指定

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

我不确定问题是什么。但可能是以下链接可以帮助你。

您也可以初始化配置以设置首选项。

$this->upload->initialize($config);

Answer 4

确保输入文件的名称设置为＆＃34; userfile＆＃34;因为上传功能需要来自输入字段的文件，其名称设置为＆＃34; userfile＆＃34;
