当我打印时，我正在尝试通过 wordpress 中的 custom.php 上传图像 

`$_FILES['uploadfiles'];`

它没有显示我之前在另一个 wordpress 网站上使用过的相同代码的任何东西，该代码在ec2我当前的 wordpress 上运行良好，在 ec2 上，并且有 bitnami 图像我已经检查了php.ini文件中的所有配置upload_tmp_dir=/opt/bitnami/php/tmp， . file_uploads=on, upload_max_filesize=40M.

我没有使用任何表单，我刚刚在一个钩子中添加了上传字段，该字段在一页上显示该字段。

我正在使用论文主题。所以任何人都知道为什么在使用此代码时会发生这种情况，而同一代码的一个副本在另一个具有大师主题的 wordpress 上工作。

贝娄是我用来上传图片的代码。

<input type="file" name="uploadfiles[]" id="uploadfiles" size="35" class="uploadfiles" />



<?php
$uploadfiles = $_FILES['uploadfiles'];

print_r ($uploadfiles);

      if ($uploadfiles['error'][$key] == 0) {

        $filetmp = $uploadfiles['tmp_name'][$key];

        //clean filename and extract extension
        $filename = $uploadfiles['name'][$key];

        // get file info
        // @fixme: wp checks the file extension....
        $filetype = wp_check_filetype( basename( $filename ), null );
        $filetitle = preg_replace('/\.[^.]+$/', '', basename( $filename ) );

          $i++;
        }

        //exit();
        $urlimage=wp_get_attachment_url( $attach_id );
          $_SESSION["oldurl"]=$urlimage;
