我是codeigniter的新手..请帮助我在codeigniter中上传图像。首先我需要在“codeigniter/userimage/”内创建一个子文件夹，用户ID作为文件夹名称。我做到了。这是我的控制器功能

function update(){
    $uppath="/var/www/html/codeigniter/userimage/";
    $sess_id=  $this->session->userdata('userid');
    $folder=$uppath.$sess_id;
    if(!is_dir($folder))
    mkdir ($folder,777);

    if($x>0){
        $config['upload_path']='./userimage/'.$folder.'/';
        $config['allowed_types'] = 'gif|jpg|png|jpeg';
        $config['max_size'] = '9000';
        $config['max_width']  = '1024';
        $config['max_height']  = '1000';
        echo 'haii'; 
        $this->load->library('upload');
        $this->upload->initialize($config);
        echo 'heloooo'; 
        if (!$this->upload->do_upload('picfile')) {
            print_r( $this->upload->display_error() );die;
        }
        else {
            $image=$this->upload->do_upload('picfile');
            // echo 'uploaded';
            echo $image;
        }
    }
}

我正在从视图'profileinfo'调用我在模型'home'中写入的方法更新。

我的视图 profileinfo 是：

`<?php
  $fn='';
 $ln='';
 $un='';
 $em='';
 $b='';
 $gr='';
 foreach ($query as $row){
 $fn=$row->firstname;
 $ln=$row->lastname;
  $un=$row->username;
  $em=$row->email;
 $b=$row->bday;
 $gr=$row->gender;
}
?>
 <html>
<head></head>
<body>
  <h1><u>My Profile Details</u></h1>
    <br><br><div id="viewdiv" align="center">

          <div align="right" style="font-weight: bold;font-size: 20px;">

        <?php

                  ?>

首先使用：

$uppath='./codeigniter/userimage/';

你的文件字段名是什么？如果不是userfile，则提供如下字段名称：

if ( ! $this->upload->do_upload('field_name'))

最后打印这样的错误进行调试：

print_r( $this->upload->display_error() );die;

编辑：

function update(){
    $uppath="/var/www/html/codeigniter/userimage/";
    $sess_id=  $this->session->userdata('userid');
    $folder=$uppath.$sess_id;
    if(!is_dir($folder))
    mkdir ($folder,777);

    if($x>0){
        $config['upload_path']      = './userimage/'.$sess_id.'/';
        $config['allowed_types']    = 'gif|jpg|png|jpeg';
        $config['max_size']         = '9000';
        $config['max_width']        = '1024';
        $config['max_height']       = '1000';
        echo 'haii'; 
        $this->load->library('upload', $config);
        //$this->upload->initialize($config);
        echo 'heloooo'; 
        if (!$this->upload->do_upload('picfile')) {
            print_r( $this->upload->display_errors() );die;
        }
        else {
            $image=$this->upload->do_upload('picfile');
            // echo 'uploaded';
            echo $image;
        }
    }
}
