</form>Controller IndexController.class.php code:
<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
public function index(){
$this->display();
}
public function upload(){
if(IS_POST){
$config = array(
'maxSize' => 3145728,
'rootPath' => './Uploads/',
'savePath' => '',
'saveName' => array('uniqid', mt_rand(1,999999).'_'.md5(uniqid())),
'exts' => array('jpg', 'gif', 'png', 'jpeg'),
'autoSub' => true,
'subName' => array('date','Ymd'),
);
$upload = new \Think\Upload($config);// 实例化上传类
$info = $upload->upload();
if(!$info) {
$this->error($upload->getError());
}else{
foreach($info as $file){
echo $file['savepath'].$file['savename'];
}
}
}else{
$this->display();
}
}
}Upload result display:
Solution:
First method:
$config = array(
'maxSize' => 3145728,
'rootPath' => './Uploads/',
'exts' => array('jpg', 'gif', 'png', 'jpeg'),
'autoSub' => true,
'subName' => array('date','Ymd'),
'saveRule' => '',
);
you can adopt the second method:
$config = array(
'maxSize' => 3145728,
'rootPath' => './Uploads/',
'saveName' => array('uniqid', mt_rand(1,999999).'_'.md5(uniqid())),
'exts' => array('jpg', 'gif', 'png', 'jpeg'),
'autoSub' => true,
'subName' => array('date','Ymd'),
);
