将不包含扩展名的文件上传到wordpress？

Question

Wordpress版本:4.7.9.

define('ALLOW_UNFILTERED_UPLOADS', true);

声明写入wp-includes/functions.php.
编辑一个名为test不包含任何扩展名的简单文件.

vim test
to upload the file which contain no file extension.

上传文件时出错test.

This file type is not allowed. Please try another.

将文件重命名test为test.txt.
并添加以下内容wp-includes/functions.php.

add_filter('upload_mimes','custom_upload_mimes');
function custom_upload_mimes ( $existing_mimes=array() ) {
     $existing_mimes['txt'] = 'application/txt';
     return $existing_mimes;
     }

该文件test.txt可以成功上传.
在配置文件中设置是没有用的wp-config.php.

define('ALLOW_UNFILTERED_UPLOADS', true);

我正在使用二十四岁的孩子.

这是我的 /var/www/html//wp-content/themes/twentyfourteen-child/functions.php

<?php
define('ALLOW_UNFILTERED_UPLOADS', true);
function my_theme_enqueue_styles() {

$parent_style = 'twentyfourteen-style'; // This is 'twentyfourteen-style' for the Twenty Fourteen theme.


wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'child-style',
get_stylesheet_directory_uri() . '/style.css',
array( $parent_style ),
wp_get_theme()->get('Version')
);
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
remove_filter('the_content', 'wptexturize');
remove_filter('the_excerpt', 'wptexturize');
remove_filter('comment_text', 'wptexturize');
?>

它不会有任何影响.

真正的问题不在于 WordPress 的后端，而在于前端验证。上传器由Plupload处理，默认情况下，WordPress 仅检查您是否ALLOW_UNFILTERED_UPLOADS在上传进度中定义，而没有真正使用该值调整前端插件的过滤器验证。也许是前端的一个小故障。

如您所见，WordPress 始终呈现以下默认设置：

var _wpPluploadSettings = {"defaults":{"file_data_name":"async-upload","url":"\/wp-admin\/async-upload.php","filters":{"max_file_size":"268435456b","mime_types":[{"extensions":"jpg,jpeg,jpe,gif,png,bmp,tiff,tif,ico,asf,asx,wmv,wmx,wm,avi,divx,flv,mov,qt,mpeg,mpg,mpe,mp4,m4v,ogv,webm,mkv,3gp,3gpp,3g2,3gp2,txt,asc,c,cc,h,srt,csv,tsv,ics,rtx,css,htm,html,vtt,dfxp,mp3,m4a,m4b,ra,ram,wav,ogg,oga,flac,mid,midi,wma,wax,mka,rtf,js,pdf,class,tar,zip,gz,gzip,rar,7z,psd,xcf,doc,pot,pps,ppt,wri,xla,xls,xlt,xlw,mdb,mpp,docx,docm,dotx,dotm,xlsx,xlsm,xlsb,xltx,xltm,xlam,pptx,pptm,ppsx,ppsm,potx,potm,ppam,sldx,sldm,onetoc,onetoc2,onetmp,onepkg,oxps,xps,odt,odp,ods,odg,odc,odb,odf,wp,wpd,key,numbers,pages"}]},"multipart_params":{"action":"upload-attachment","_wpnonce":"9ee7fbf228"}},"browser":{"mobile":false,"supported":true},"limitExceeded":false};

在最终解决问题之前，对问题的临时解决方案是挂钩 WordPress 调用以生成前端设置的过滤器plupload_default_settings。

将过滤器添加到您的functions.php：

add_filter('plupload_default_settings', function ($settings) {
    if (defined('ALLOW_UNFILTERED_UPLOADS') && ALLOW_UNFILTERED_UPLOADS) {
        unset($settings['filters']['mime_types']);
    }

    return $settings;
});

test这将允许您通过上传器上传您的内容。由于 WordPress 已经在后端进行检查，因此只要您在wp-config.phpthat ALLOW_UNFILTERED_UPLOADSis中定义了它true，它就应该正确上传。
