例,利用图片高与宽生+文件名成名字
代码如下
代码如下 | 复制代码 |
add_filter( 'wp_handle_upload_prefilter', 'modify_uploaded_file_names', 20); function modify_uploaded_file_names( $image ) { |
例,利用年月日时分秒+千位毫秒整数
以wordpress 3.2.1为例,打开“wp-admin/includes/file.php” www.111cn.net文件,找到第327行这段代码:
代码如下 | 复制代码 |
// Move the file to the uploads dir $new_file = $uploads['path'] . "/$filename"; if ( false === @ move_uploaded_file( $file['tmp_name'], $new_file ) ) return $upload_error_handler( $file, sprintf( __('The uploaded file could not be moved to %s.' ), $uploads['path'] ) ); |
将其修改为
代码如下 | 复制代码 |
// Move the file to the uploads dir $new_file = $uploads['path'] . "/".date("YmdHis").floor(microtime()*1000).".".$ext; if ( false === @ move_uploaded_file( $file['tmp_name'], $new_file ) ) return $upload_error_handler( $file, sprintf( __('The uploaded file could not be moved to %s.' ), $uploads['path'] ) ); |
保存,重新上传文件。这样,新上传的文件,就会自动保存为“年月日时分秒+千位毫秒整数”的新文件名,并保存到相应的年月文件夹之下了。
提醒你,这两种方法个人觉得后者更适合我们一些哦,因为按年月日时分秒+千位毫秒整数不会出现重复名字,而按图片高与宽生+文件名成名字还有可能存在重复名字
