Thinkphp3.2 solve the problem of uploading a single file with multiple files upload method

HTML Simple page:

Index.html Code:

<form action= "{: U (' Index/upload ')}" method= "Post" enctype= "Multipart/form-data" >    file Upload: <input type= " File "name =" test[] ">    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 = "test[" >    file Upload: <input type= "file" name = "test[" ">    File Upload: <input type=" File "name =" test[] ">    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[]" >    <input type= "Submit" value = "Commit" ></form>

Controller IndexController.class.php Code:

<?phpnamespace home\controller;use Think\controller;class Indexcontroller extends Controller {public function I    Ndex () {$this->display ();                              The Public Function upload () {if (is_post) {$config = array (    ' MaxSize ' + 3145728, ' rootpath ' + './uploads/', ' savepath ' = ', ' savename ' = = Array (' Uniqid ', Mt_rand (1,999999). ' _ '. MD5 (Uniqid ())), ' exts ' = = Array (' jpg ', ' gif ', ' PNG ', ' jpeg '), ' autosub ' =&    Gt                        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!
