Question

我使用过BuddyPress Docs。当我尝试从我的前端网站上传图像时。它将与订户成功上传。但是当我尝试上传.xlsx文件的.PDF时，它会给我一个错误

抱歉，出于安全原因，不允许使用此文件类型。

但是当我将用户的角色更改为管理员而不是.PDF时，.xlsx文件也会被上传。那么如何将所有文件类型的媒体权限授予所有用户角色。我还在我的/wp-content/themes/my-theme/functions.php

中添加了以下内容

add_filter('upload_mimes','add_custom_mime_types');
function add_custom_mime_types($mimes) {
    return array_merge($mimes,array (
            'pdf'                          => 'application/pdf',
            'doc'                          => 'application/msword',
            'pot|pps|ppt'                  => 'application/vnd.ms-powerpoint',

Answer 1

WordPress不允许我们在媒体库中上传所有类型的文件，即使您收到错误的zip文件也是如此。

方法1：

过滤钩

正确的功能如下（将此代码放在function.php文件中），如果您想允许其他文件类型，只需将它们添加到$exisiting_mimes数组中：

<?php
add_filter('upload_mimes', 'add_custom_upload_mimes');
if (!function_exists('add_custom_upload_mimes')) {
 function add_custom_upload_mimes( $existing_mimes ){
  $existing_mimes['zip']  = 'application/zip';
  $existing_mimes['swf']  = 'application/x-shockwave-flash';
  $existing_mimes['rtf']  = 'text/richtext';
  $existing_mimes['tiff'] = 'image/tiff';
  $existing_mimes['pdf']  = 'application/pdf';
  $existing_mimes['doc']  = 'application/msword';
  return $existing_mimes;
 }
}
?>

还有其他方法可以禁用文件类型上传限制。对于某些人来说，第一种方法是可以的，但对于其他人，他们不断在博客上上传不同类型的文件，这不是一个好的解决方案。

方法2：

禁用过滤

在WordPress中禁止某些类型文件的过程称为过滤。您可以使用以下代码禁用此过滤。您必须在wp-config.php中添加它。 define('ALLOW_UNFILTERED_UPLOADS', true);

注意：现在您已允许上传博客上的所有类型的文件。这可能会导致严重的安全问题。如果管理不当，请注意上传到服务器上的任何文件都可以执行。

Just Replace with this code
