我想将文件上传到服务器，但 $_FILES 数组似乎是空的 .

我的代码下面有什么问题吗？

<form action='' method='POST' enctype='multipart/form-data'> 
                <table class='table table-striped table-hover'> 
                    <tr> 
                        <td> 
                            Bestand(en)
                        </td>
                        <td> <input type='file' name='fotos[]' multiple='multiple' /> </td>

                    </tr>
                    <tr> 
                        <td> Aangepaste bestandsnaam </td>
                        <td> <input type='text' name='naam' class='form-control' /> </td>
                    </tr>
                    <tr> 

                        <td> <input type='submit' class='btn btn-primary' value='Fotos toevoegen' name='fotos_toevoegen' /> </td>
                        <td></td>
                    </tr>
                </table>
            </form>

PHP代码

if(isset($_POST['fotos_toevoegen'])){

    print_r($_FILES['fotos']['name']);

    $array_lenght = count($_FILES['fotos']['name']);
    //print_r($_FILES['fotos']);
    for($i = 0; $i < $array_lenght; $i++){

        $array_fotos = array();

        // trek $_FILES uit elkaar zodat je individuele foto kan toevoegen.
        foreach($_FILES['fotos'] as $key => $value){
            $array_fotos[$key] = $_FILES['fotos'][$key][$i];
        }



        $foto = new Foto();

        $foto->path = $path . '/cms/fotos/orginele-bestanden';
        $foto->naam = $_POST['naam'].'-'. $i;
        $foto->album_id = $session_album_id;
        $foto->file_info = $array_fotos;
        $foto->width_thumbnail = 300;
        $foto->height_thumbnail = 250;
        $foto->width_grootformaat = 500;
        $foto->height_grootformaat = 400;

        $foto->to_string();

        //$foto_beheer->add($foto);
    }


}

Print_r（$ _ FILES ['fotos']）向我显示：Array（[name] => Array（[0] => pannekoeken4.jpg [1] => pannekoeken5.jpg）[type] =>数组（[0] => [1] =>）[tmp_name] =>数组（[0] => [1] =>）[错误] =>数组（[0] => 6 [1] => 6）[size] = >数组（[0] => 0 [1] => 0））

    一些非常基本的测试给了我以下结果：

    <?php
if(isset($_POST)){
  echo '<pre>';
  var_dump($_POST);
  var_dump($_FILES);
  echo '</pre>';
}


?>
<form action='testfile.php' method='POST' enctype='multipart/form-data'> 
                <table class='table table-striped table-hover'> 
                    <tr> 
                        <td> 
                            Bestand(en)
                        </td>
                        <td> <input type='file' name='fotos[]' multiple='multiple' /> </td>

                    </tr>
                    <tr> 
                        <td> Aangepaste bestandsnaam </td>
                        <td> <input type='text' name='naam' class='form-control' /> </td>
                    </tr>
                    <tr> 

                        <td> <input type='submit' class='btn btn-primary' value='Fotos toevoegen' name='fotos_toevoegen' /> </td>
                        <td></td>
                    </tr>
                </table>
            </form>

    输出：

    array(2) {
  ["naam"]=>
  string(17) "customfilename"
  ["fotos_toevoegen"]=>
  string(15) "Fotos toevoegen"
}
array(1) {
  ["fotos"]=>
  array(5) {
    ["name"]=>
    array(1) {
      [0]=>
      string(50) "2014-10-06.pdf"
    }
    ["type"]=>
    array(1) {
      [0]=>
      string(15) "application/pdf"
    }
    ["tmp_name"]=>
    array(1) {
      [0]=>
      string(36) "/Applications/MAMP/tmp/php/php79bugX"
    }
    ["error"]=>
    array(1) {
      [0]=>
      int(0)
    }
    ["size"]=>
    array(1) {
      [0]=>
      int(770241)
    }
  }
}

    您能否根据为post_max_size配置的值检查上传文件的大小

    如果发布数据的大小大于post_max_size，则$ _POST和$ _FILES超全局变量为空 .
