我需要这个来上传和调整图像大小 . 我一直收到404错误，不知道为什么 . 它也假设在成功页面上输出图像，但我没有那么胖 . 我不太擅长codeignighter任何帮助表示赞赏 .
已知问题我在MySQL中放入图像的表称为image_upload . 我知道这个从未被引用过，我现在知道我想在构造中有一个 $this->load->database(); .
controller
<?php
class Upload extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
public function index()
{
$this->load->view('upload_form', array('error' => ' ' ));
}
public function do_upload()
{
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
$this->upload->do_upload('image');
$fInfo = $this->upload->data(); // get all info of uploaded file
//for image resize
$img_array = array();
$img_array['image_library'] = 'gd2';
$img_array['maintain_ratio'] = TRUE;
$img_array['create_thumb'] = TRUE;
//you need this setting to tell the image lib which image to process
$img_array['source_image'] = $fInfo['full_path'];
$img_array['width'] = 113;
$img_array['height'] = 75;
$this->image_lib->clear(); // added this line
$this->image_lib->initialize($img_array); // added this line
if (!$this->image_lib->resize())
if ( ! $this->upload->do_upload('userfile'))
{
$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);
}
}
}

将其更改为输入类型文件名
如果图像成功上传，则调整图像大小调整代码
