<h2><span class="ask-title">附件地址</span></h2>
<span class="ask-title">wp-content/uploads/年/月/日</span>

例子

<span style="color: #ff0000;">/wp-content/uploads/2024/10/07/</span>20241007214227417.png

/wp-content/uploads/2024/10/07/<span style="color: #ff0000;">原版没有日期只有年月</span>
<pre class="line-numbers language-markup"><code class="language-markup">/** wordpress年月日文件目录**/
function custom_upload_directory( $uploads ) {
date_default_timezone_set("Asia/Shanghai");//设置时区
$subdir = date("Y/m/d");//设置目录格式
$uploads['subdir'] = $subdir;
$uploads['path'] = $uploads['basedir'].DIRECTORY_SEPARATOR.$subdir;
$uploads['url'] = $uploads['baseurl'].'/'.$subdir;
return $uploads;
}
add_filter( 'upload_dir', 'custom_upload_directory' );</code></pre>
需要在主题文件夹下，修改function.php函数，实现文件上传目录由原来的"wp-content/uploads/年/月"的方式，修改为"wp-content/uploads/年/月/日"
<h2>上传附件重命名</h2>
<span class="ask-title">wp-content/uploads/年/月/日</span>

例子

/wp-content/uploads/2024/10/07/<span style="color: #ff0000;">20241007214227417.png</span>

<span style="color: #ff0000;">20241007214227417</span>随日期生成
<pre class="line-numbers language-php"><code class="language-php">add_filter('wp_handle_upload_prefilter', 'custom_upload_filter' );
function custom_upload_filter( $file ){
    $info = pathinfo($file['name']);
    $ext = $info['extension'];
    $filedate = date('YmdHis').rand(10,99);//为了避免时间重复，再加一段2位的随机数
    $file['name'] = $filedate.'.'.$ext;
    return $file;
}
</code></pre>
&nbsp;

以下是随机生成附件名字

如果位数够的话，就不用看其它的。
<pre class="line-numbers language-php"><code class="language-php">// WordPress上传图片或文件自动重命名的方法
// https://themebetter.com/wordpress-upload-auto-filename.html
add_filter('sanitize_file_name', 'tbwp_new_filename', 10);
function tbwp_new_filename($filename) {
    $info = pathinfo($filename);
    $ext = empty($info['extension']) ? '' : '.' . $info['extension'];
    $name = basename($filename, $ext);
    return substr(md5($name), 0, 15) . $ext;
}
</code></pre>
<h2 id="65873">文件名md5转码为32位字符串</h2>
<pre class="line-numbers language-php">
add_filter('wp_handle_upload_prefilter', 'custom_upload_filter' );
function custom_upload_filter( $file ){
    $info = pathinfo($file['name']);
    $ext = '.' . $info['extension'];
    $md5 = md5($file['name']);
    $file['name'] = $md5.$ext;
    return $file;
}

</pre>
以上附件重命名只能用一种，不能重复。
<h2>后台媒体库路径修改</h2>
以前的版本是有后台设置功能的，恢复后台功能代码如下，本人没测试过，你可以试试，放到functions.php
<pre class="line-numbers language-php"><code class="language-php">//找回上传设置
if(get_option('upload_path')=='wp-content/uploads' || get_option('upload_path')==null) {
    update_option('upload_path',WP_CONTENT_DIR.'/uploads');
}
</code></pre>
