ThinkPHP3.0 thumbnail cannot be saved to subdirectory solution summary_PHP tutorial

Thumbnails cannot be saved to subdirectories after uploading files in THINKPHP3.0. This is because the getSubName() function in the upload class UploadFile.class.php can only create a subdirectory of the original image but not a subdirectory of the thumbnail. , it can be said to be a BUG.

Solution 1 (the official solution provided by ThinkPHP, I have not tested it): Upgrade to the latest UploadFile.class.php of ThinkPHP3.1 (https://github.com/liu21st/extend/tree/master/Extend /Library/ORG/Net), replace the original UploadFile.class.php
after downloading

Solution 2: Modify some codes of UploadFile.class.php

This is my own solution, add a thumbnail subdirectory generation function

Step 1>>

Imitate the getSubName() function in UploadFile.class.php to create a getThumbSubName() function

　　　$dir = date($this->dateFormat,time()); 　　　break;

The code is as follows

代码如下

复制代码

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; }

Copy code

private function getThumbSubName($file) {

switch($this->subType) {

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

​​case 'date':

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>>

Change line 158 in UploadFile.class.php to

The code is as follows

Copy code

$thumbPath = $this->thumbPath?$this->thumbPath.($this->autoSub?$this->getThumbSubName($file).'/':''):$file[ 'savepath']; http://www.bkjia.com/PHPjc/632175.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/632175.htmlTechArticleTHINKPHP3.0 After uploading the file, the thumbnail cannot be saved to the subdirectory because of the UploadFile.class.php upload The getSubName() function in the class can only create a subdirectory of the original image but cannot create a thumbnail image...
