Wordpress Chinese user name login (user name cannot use Chinese)

Wordpress cannot register a Chinese user name

We can make the following changes to allow wordpress to log on with a Chinese user name:

1. Open the wp-uplodes/formatting. Php file.

2. Find

Function sanitize_user ($ username, $ strict = false) {3. Add

$ Strict = false; this function can be implemented through a simple trilogy. The principle is also very simple. Force $ strict = false, in this way, wordpress does not strictly process the user name characters when registering or modifying the user name, and the Chinese user name can be used normally.

 

1. Security question: If any string can be registered as a user name, will it pose a threat to your website?
2. coverage after upgrade: If you upgrade wordpress, wp-nodes des/formatting. the PHP file will be overwritten by the upgrade file. You need to modify it again. Otherwise, new users may no longer be able to use the Chinese user name, the original Chinese user name may also encounter problems such as information modification and logon.

Another solution

By default, a wordpress blog does not support registering a Chinese user name. Whether you register a user at the front-end or you add a Chinese user in the background, the user will prompt "this user name contains invalid characters ". To solve this problem, you can modify the code or use the plug-in.

Modify the code to open the formatting. Php file under the wp-uplodes Directory, search for "function sanitize_user ($ username, $ strict = false)", and add the code "$ strict = false;" under it ;"
Function sanitize_user ($ username, $ strict = false)
{
$ Strict = false; // solve the problem that the Chinese user name cannot be registered
$ Raw_username = $ username;
$ Username = wp_strip_all_tags ($ username );
$ Username = remove_accents ($ username );
}

The disadvantage of modifying the code to solve the problem is that you need to perform the operation again after each WordPress upgrade.

Now we can implement Chinese login.
