codeigniter照片拇指创建和上传

它提供了一个空白屏幕：/它上传第一个图像，这很好。然后调用_create_thumbnail，在“$this->image_lib->resize（）”行显示空白屏幕：

知道有什么问题吗

谢谢

在此处检查您的花括号：

if（！$this->upload->do_upload（））echo$this->upload->display_errors（）；
否则{

看起来您在混合语法样式。

尝试删除

$fileName

：

而不是：

$config['source_image']=“uploads/”。$fileName；

使用此选项：

$config['source\u image']=“uploads/”

尝试此选项

function _create_thumbnail($fileName) 
 {
$this->load->library('image_lib');
         $config['image_library'] = 'gd2';
         $config['source_image'] = './uploads/' . $fileName;       
         $config['create_thumb'] = TRUE;
         $config['maintain_ratio'] = TRUE;
         $config['width'] = 210;
         $config['height'] = 160;
         $config['new_image'] = './uploads/'.$fileName;

         $this->image_lib->initialize($config);
         if(!$this->image_lib->resize()) echo
 $this->image_lib->display_errors();

 }

function _create_thumbnail($fileName) 
 {
$this->load->library('image_lib');
         $config['image_library'] = 'gd2';
         $config['source_image'] = './uploads/' . $fileName;       
         $config['create_thumb'] = TRUE;
         $config['maintain_ratio'] = TRUE;
         $config['width'] = 210;
         $config['height'] = 160;
         $config['new_image'] = './uploads/'.$fileName;

         $this->image_lib->initialize($config);
         if(!$this->image_lib->resize()) echo
 $this->image_lib->display_errors();

 }
