ThinkPHP3.0 thumbnail cannot be saved to a subdirectory

Solution 1 (ThinkPHP official offer, I have not tested) : upgrade to ThinkPHP3. 1 latest UploadFile. class. php (https: / / github com/liu21st/extend/tree/master/Extend/Library/ORG/Net), replace the original UploadFile. After downloading class. php

Solution 2: modify part of the code for UploadFile.class.php

This is to do their own solution, add a slightly thumbnail subdirectory generation function
Step 1 > >

UploadFile.class.php creates an getThumbSubName() function that mimics the getSubName() function

 
private function getThumbSubName($file) { 
　　switch($this->subType) { 
　　　　case 'date': 
　　　　　　$dir = date($this->dateFormat,time()); 
　　　　　　break; 
　　　　case 'hash': 
　　　　default: 
　　　　　　$name = md5($this->thumbPath); 
　　　　　　$dir = ''; 
　　　　　　for($i=0;$i<$this->hashLevel;$i++) { 
　　　　　　　　$dir .= $name{$i}.'/'; 
　　　　　　} 
　　　　　　break; 
　　} 
　　if(!is_dir(($this->thumbPath).$dir)) { 
　　　　mkdir(($this->thumbPath).$dir); 
　　} 
　　return $dir; 
} 

Step 2 > >

In UploadFile.class.php, line 158 is changed

 
$thumbPath = $this->thumbPath?$this->thumbPath.($this->autoSub?$this->getThumbSubName($file).'/':''):$file['savepath']; 

Finally problem solved!
