WordPress 3.9.0上传文件自动重命名文件方法
在以前我记得分享一篇在上传文件时按日期自动生成一个名字,这样可以防止有重复的文件名替换了,下面我今天再分享一个差不多功能的处理方法:
打开[wp-admin/includes/file.php]文件,找到第313行和452行这段代码:
$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:
$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.' ), $error_path ) );
}
核心代码上图红色那一行,代码如下:
date("YmdHis").floor(microtime()*1000).".".$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的形式了,最后我们再把文件保存之后上传到空间就可以了.
