WordPress 3.9.0上传文件自动重命名文件方法

作者：袖梨 2022-06-25

打开“wp-admin/includes/file.php”文件，找到第313行和452行这段代码：

代码如下

复制代码

$new_file = $uploads['path'] . "/$filename"; //主要是修改这行的代码！
if ( false === @ rename( $file['tmp_name'], $new_file ) ) {
if ( 0 === strpos( $uploads['basedir'], ABSPATH ) )
$error_path = str_replace( ABSPATH, '', $uploads['basedir'] ) . $uploads['subdir'];
else
$error_path = basename( $uploads['basedir'] ) . $uploads['subdir'];
return $upload_error_handler( $file, sprintf( __('The uploaded file could not be moved to %s.' ), $error_path ) );
}

把上面代码改成如下代码

代码如下

复制代码

$new_file = $uploads['path'] . "/".date("YmdHis").floor(microtime()*1000).".".$ext; //主要是修改这行的代码！
if ( false === @ rename( $file['tmp_name'], $new_file ) ) {
if ( 0 === strpos( $uploads['basedir'], ABSPATH ) )
$error_path = str_replace( ABSPATH, '', $uploads['basedir'] ) . $uploads['subdir'];
else
$error_path = basename( $uploads['basedir'] ) . $uploads['subdir'];
return $upload_error_handler( $file, sprintf( __('The uploaded file could not be moved to %s.' ), $error_path ) );
}

核心代码上图红色那一行

代码如下

复制代码

date("YmdHis").floor(microtime()*1000).".".$ext;

当然你也可以改更详细一些，如果你每天有大量文件上传我们可以这样修改日期分类

date("Y/M/d").floor(microtime()*1000).".".$ext;

这样就生成了如

/2013/06/18/123123.gif

了哦

最后我们再把文件保存之后上传到空间就可以了哦。
