Question

我们正在尝试使用Codeigniter上传一些文件，但出于某种原因，这段代码无效。

将图书馆加载到＆＃34; autoload＆＃34;由于显而易见的原因，它仍然不是最佳解决方案。

奇怪的是，我正在另一个网站工作。

<?php
// set options
$config['upload_path']      = FCPATH.$path;
$config['allowed_types']    = 'png|jpeg|jpg|gif';
$config['max_size']         = 2048;
$config['encrypt_name']     = TRUE;
$config['overwrite']        = TRUE;
$config['max_width']        = 0;
$config['max_height']       = 0;
// check if folder exists
if( ! is_dir($config['upload_path']))
  @mkdir($config['upload_path'], 0755, true);
//load upload library
$this->load->library('upload', $config);
//check success of upload
if( ! $this->upload->do_upload($name)) 
  return $this->upload->display_errors();
else
{
  // do upload
}
?>

这是错误：

A PHP Error was encountered

Severity: Notice

Message: Undefined property: xxx::$upload

Filename: core/xxx.php

Line Number: 424

Fatal error: Call to a member function do_upload() on null

首先确保$path是正确的var dump（$ path）并检查是否接收它。

其次，如果do_upload的一部分和is目录周围没有任何{}

public function do_upload() {

$config['upload_path']      = FCPATH . 'uploads/';
$config['allowed_types']    = 'png|jpeg|jpg';
$config['max_size']         = 2048;
$config['encrypt_name']     = TRUE;
$config['max_size'] = '30000'; // Added Max Size
$config['overwrite']        = TRUE;
$config['max_width']        = 0;
$config['max_height']       = 0;

//load upload library

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

// check if folder exists

if( ! is_dir($config['upload_path'])) {
@mkdir($config['upload_path'], 0755, true);
}

//check success of upload

$name = "userfile"; // Field name

if( ! $this->upload->do_upload($name)) {

  $error = array('error' => $this->upload->display_errors());

  $this->load->view('upload_form', $error);

} else {

  $data = array('upload_data' => $this->upload->data());

  $this->load->view('upload_success', $data);

}

}

确保在视图中使用echo form_open_multipart('controller/do_upload')
