问题描述

我正在尝试在代码点火器中制作图像上传表单,但出现以下错误。

严重性:通知

消息:未定义索引:image_file

文件名:控制器/men.php

行号:23

回溯:

文件:C:\xampp\htdocs\CodeIgniter-3.1.8\application\controllers\men.php 行:23 功能:_error_handler

文件:C:\xampp\htdocs\CodeIgniter-3.1.8\index.php 行:315 功能:require_once

这是我的视图、控制器和模型代码

1) 查看

<!DOCTYPE html>
<html>
    <head>
        <title>image</title>
        <link rel="stylesheet" type="text/css" href="<?php echo base_url();?>/public/css/bootstrap.css">
    </head>
    <body>
        <form method="post" action="<?php echo base_url()?>men/image_upload" id="upload_form" />
            <input type="file" name="image_file">
            <input type="submit" id="upload" name="upload" value="Upload" />
        </form>
    </body>
</html>

2) 控制器

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Men extends CI_Controller
{
    public function index(){
        $this->load->view("imageupload");
    }

    public function image_upload(){
        $config['upload_path']='./uploads';
        $config['allowed_types']='*';
        $this->load->library('upload',$config);
        $this->upload->do_upload('image_file');
        $image_file = $this->upload->data();
        $data=array('image_file'=> $image_file['image_file']);
        $this->load->model("mymodel");
        $this->mymodel->imagedone($data);   
    }
}
?>

3) 型号

<?php
class Mymodel extends CI_Model{

    function imagedone($data){
        $query = $this->db->insert("image_tbl",$data);
        if($query)
        {
            echo "File is uploaded";
        }
        else{
            echo "failure";
        }
    } 
}

解决方案


这个错误可能是由于表单标签的属性缺失导致的,在表单标签中添加 -> enctype="multipart/form-data" 属性并尝试如下:

<form method="post" action="<?php echo base_url()?>men/image_upload" id="upload_form" enctype="multipart/form-data" /> <input type="file" name="image_file"> <input type="submit" id="upload" name="upload" value="Upload" /> </form>
