WordPress Chinese name, numeric name image upload automatic renaming code

The code and method for automatically renaming images uploaded by WordPress are already very messy on the Internet. They are even basically the same functions. The compatibility and effect are not so ideal. For example, on the php Chinese website Free WordPress template download## Many # areas are like this, so we have improved these codes to make the WordPress media library upload more compatible with images with Chinese names and meaningless numerical names.

#When we use WordPress to publish articles, we often need to add pictures, multimedia, etc. However, everyone knows that WordPress is a foreign product, and its support for Chinese and for some domestic friends who are paranoid about using Windows Server system servers are not so impressive. It is also for us Chinese users that we are all used to it. Or you like to name the picture in Chinese, but due to the mechanism of WordPress, the picture cannot be displayed normally or there are various problems. Therefore, we need to bring you a comprehensive and high-quality WordPress Chinese name image upload solution.

It is still the old rule of WordPress. Add the following code to the functions.php of the current theme:

//WordPress中文名、数字名图片上传自动重命名
add_filter('sanitize_file_name','fanly_custom_upload_name', 5, 1 );
function fanly_custom_upload_name($file){
$info= pathinfo($file);
$ext= empty($info['extension']) ? '' : '.' . $info['extension'];
$name= basename($file, $ext);
if(preg_match("/[一-龥]/u",$file)){//中文换名
$file= substr(md5($name), 0, 20) . rand(00,99) . $ext;//截取前20位MD5长度，加上两位随机
}elseif(is_numeric($name)){//数字换名
$file= substr(md5($name), 0, 20) . rand(00,99) . $ext;//截取前20位MD5长度，加上两位随机
}
    return $file;
}

Using the above code can also solve the problem of uploading Chinese name image attachments to WordPress articles. To solve the problem of garbled characters or non-display, you can automatically use MD5 encryption to rename and intercept images with Chinese names and meaningless pure numerical names. Compared with automatic renaming of other WordPress images, it is more compatible and has better effects. Some.

But in the end, I still have some suggestions. If you pay attention to the optimization of pictures, it is still possible to use English words/phrases or Chinese pinyin for naming pictures, which is more conducive to naming pictures. Optimization. The encrypted naming method of the above code using MD5 is actually not conducive to image optimization, but it just seems to have a higher desire and quality to show off. Of course, pictures should still add alt description attributes reasonably to optimize the most beneficial image.
