多个文件上载导致foreach（）错误 [英] Multiple File Upload results in foreach() error

问题描述

实际上试图用一种重命名的方式一次上传多个图片到一个文件夹中。上传到foreach循环。然而，它在这一点上停止：

$ foreach $ _FILES ['pictures'] ['name'] as $ f = $ name $）{
if（$ _FILES ['pictures'] ['error'] [$ f] == 0）{
$ name = $ date;
$ name。= - ;
$ name。= $ i;
$ name。=。;
$ extsearch = $ _FILES ['pictures'] ['name'] [$ f];
$ ext = pathinfo（$ extsearch，PATHINFO_EXTENSION）;
$ name。= $ ext;
if（move_uploaded_file（$ _ FILES [pictures] [tmp_name] [$ f]，$ path。$ name））{
if（$ i == 1）{
create_image_thumb（$ albumFolder，$ name）;
}
$ i ++;
resize_image（$ albumFolder，$ name）;





$ b然而，我收到这个错误在error_log中，文件不会被移动：

  PHP警告：为/ home / clublabo中的foreach /public_html/management/create_album_action.php on line 43 
  

更新：这里是HTML代码：

 < form class =form form-horizo​​ntalaction =create_album_action.phpmethod =postenctype =multipart /表单数据> 
< div class =form-group> 
< label for =email-2class =col-sm-3 col-md-4 control-label>日期< / label>

也许你们有任何想法如何解决？

感谢：）

解决方案

替换：

 < input name =picturesid =password-2class =form-controltype =filemultiple> 
  

：

 < input name =pictures []id =password-2class =form-controltype =filemultiple> 
  

Actually trying to upload multiple pictures in a folder at once with some kind of renaming. The upload goes to the foreach loop. However, it does stop at this point:

foreach ($_FILES['pictures']['name'] as $f => $name) {
        if ($_FILES['pictures']['error'][$f] == 0) {
            $name = $date;
            $name .= "-";
            $name .= $i;
            $name .= ".";
            $extsearch = $_FILES['pictures']['name'][$f];
            $ext = pathinfo($extsearch, PATHINFO_EXTENSION);
            $name .= $ext;
            if(move_uploaded_file($_FILES["pictures"]["tmp_name"][$f], $path.$name)) {
                if ($i == 1) {
                    create_image_thumb($albumFolder, $name);
                }
                $i++;
                resize_image($albumFolder, $name);
            }
        }
    }

However, I receive this error in the error_log and the files aren't moved:

PHP Warning:  Invalid argument supplied for foreach() in /home/clublabo/public_html/management/create_album_action.php on line 43

UPDATE: Here is the HTML Code:

<form class="form form-horizontal" action="create_album_action.php" method="post" enctype="multipart/form-data">
              <div class="form-group">
                <label for="email-2" class="col-sm-3 col-md-4 control-label">Date</label>
                <div class="col-sm-6 col-md-4">
                  <div class="input-with-icon">
                  <input name="dateAlbum" class="form-control" type="text" value="<?php echo date('Y-m-d'); ?>" data-provide="datepicker" data-date-autoclose="true" data-date-format="yyyy-mm-dd"><span class="icon icon-calendar input-icon"></span></div>
                </div>
              </div>
              <div class="form-group">
                <label for="password-2" class="col-sm-3 col-md-4 control-label">Pictures</label>
                <div class="col-sm-6 col-md-4">
                  <input name="pictures" id="password-2" class="form-control" type="file" multiple>
                </div>
              </div>
              <div class="form-group">
                <div class="col-sm-offset-3 col-sm-6 col-md-offset-4 col-md-4">
                  <button class="btn btn-primary pull-right" type="submit">Create Album</button>
                </div>
              </div>
            </form>

Maybe you guys has any Idea how to have this resolved?

Thanks :)

解决方案

Replace:

<input name="pictures" id="password-2" class="form-control" type="file" multiple>

with:

<input name="pictures[]" id="password-2" class="form-control" type="file" multiple>
