CodeIgniter中的图像操作 [英] Image Manipulation in CodeIgniter

问题描述

我使用CodeIgniter 1.7处理图片时遇到了一些问题。使用以下代码，图像正确上传。唉，而不是一个新的图像，然后修改;则修改现有图像。任何帮助？

I am having some trouble manipulating images using CodeIgniter 1.7. With the following code, the image is uploaded correctly. Alas, instead of a new image being made, and then modified; the existing image is modified. Any help?

//Upload image first
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|bmp';

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

//Now fix the image
$picloc = $this->upload->data();
$picloc = $picloc['file_name'];

$thumbnail = "thumb_".$picloc;

$imagemanip['image_library'] = 'gd2';
$imagemanip['source_image'] = './uploads/'.$picloc;
$imagemanip['new_img'] = './uploads/'.$thumbnail;
$imagemanip['maintain_ratio'] = TRUE;
$imagemanip['width'] = 250;
$imagemanip['height'] = 250;

$this->load->library('image_lib', $imagemanip);

$this->image_lib->resize();

推荐答案

问题很简单，行：

$imagemanip['new_img'] = './uploads/'.$thumbnail;

索引应该是new_image，而不是new_img / p>

The the index should be "new_image", not "new_img", so the line becomes..

$imagemanip['new_image'] = './uploads/'.$thumbnail;
