Question

我正在进行多个文件上传，工作正常。我得到两个图像，但另一个图像是thumnail没有得到他们的给定路径，也没有改变到拇指大小。

我希望在＆＃34;缩略图创建开始＆＃34; 区域中出现缩略图问题。检查我的阵列，让我知道我的错误。

Answer 1

为图像配置后，即设置图像属性，然后清除并启动image_lib即可生效。

$this->image_lib->clear();
$this->image_lib->initialize($config);
$this->image_lib->resize();

注意：

确保您需要$config或$config1
确保您拥有source_image路径

Answer 2

替换

$config1['source_image'] = $image['full_path'];

要

$config1['source_image'] = $data['full_path'];

同时删除以下注释行

$this->image_lib->resize();
//$this->upload->do_upload();
//$data = $this->upload->data();
