The following for everyone to bring a Thinkphp3.2 simple solution to upload a multi-file upload only one problem. Content is very good, now share to everyone, but also for everyone to make a reference.

HTML Simple page:

Index.html Code:

<form action= "{: U (' Index/upload ')}" method= "Post" enctype= "multipart/form-data" > File upload: <input type= "Files" Name = "test[" > File upload: <input type= "file" name = "test[]" > File upload: <input type= "file" name = "test[]" > File upload: < Input type= "file" name = "test[]" > File upload: <input type= "file" name = "test[]" > File upload: <input type= "file" name = "T est[] "> Upload: <input type=" file "name =" test[] "> File upload: <input type=" file "name =" test[] "> File upload: <input ty pe= "file" name = "test[]" > File upload: <input type= "file" name = "test[]" > File upload: <input type= "file" name = "test[" " ; File Upload: <input type= "file" name = "test[]" > <input type= "submit" value = "Submit" ></form>

Controller IndexController.class.php Code:

<?phpnamespace 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);//instantiation of upload class   $info = $upload->upload ();   if (! $info) {    $this->error ($upload->geterror ());   } else{    foreach ($info as $file) {     echo $file [' Savepath ']. $file [' Savename '];    }   }  else{   $this->display ();}}}  

Upload Results display:

Many people in the multi-file upload, the last to find just upload a, mainly because of the name, because it is the same names, so the last picture left
Workaround: The first type:

$config = Array (    ' maxSize ' = = 3145728,    ' rootpath ' = './uploads/',    ' exts ' = =  Array (' jpg ', ' GIF ', ' PNG ', ' jpeg '),    ' autosub ' = True,    ' subname ' = = Array (' Date ', ' YMD '),    ' saverule ' =   ', ' );

Empty $config inside the Saverule, after the name of the upload: 59c8d38cdb968.jpg

If you feel this name is unreliable, you can take a second approach:

$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 '),   );

Set $config: ' savename ' = = Array (' Uniqid ', Mt_rand (1,999999). ' _ '. MD5 (Uniqid ())),

The final results are similar to: 672563_30ad4d8a2aafc832363de8edc1940b5c59c8d44a303f9.jpg

However, the name can be modified as needed, many file upload method, here is just a simple and convenient way!
