PHP -- CI(CodeIgniter)框架文件或图片上传的实现-php开发知识文章-编程文章分享

本文主要介绍了PHP -- CI(CodeIgniter)框架文件或图片上传的实现方法。分享给大家供大家参考，欢迎大家的学习。

先在“./application/views/”文件夹下创一个视图文件：text.php，代码如下：

<html>
<head>
    <title>文件上传</title>
</head>
<body>
<?php echo $error; ?>
<?php echo form_open_multipart('web/upload'); ?>
<input type="file" name="userfile" />
<input type="submit" value="upload"/>
</body>
</html>

Codeigniter框架有非常丰富upload类库

在Controller中一个Upload.php文件，代码如下：

class Upload extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->helper("form", "url");
    }

    public function index()
    {
        $this->load->view('test', array("error" => ''));
    }

    public function do_upload()
    {
        $config['upload_path'] = './upload/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = 100;
        $config['max_width'] = 90;
        $config['max_height'] = 768;
        $this->load->library('upload', $config);
        if (!$this->upload->do_upload('userfile')) {
            $error = array('error' => $this->upload->display_errors());
            $this->load->view('test', $error);
        } else {
            $data = array('upload_data' => $this->upload->data());
            $this->load->view('upload_success', $data);
        }
    }
}

在视图中创建另外一个文件upload_success.php

<html>
<head><title>上传结果</title></head>
<body>
<h3>上传成功</h3>
<ul>
    <?php
    foreach ($upload_data as $item => $value){?>
    <li><?php echo $item; ?>:<?php echo $value; ?></li> 
    <?php }?>    
</ul>
</body>
</html>
