Add user meta is saving more values

[egyptimhotep]

On single.php place this function and open single post, meta is working fine, "fero" is saved one time. Then open another blog post, you will see that now it save two times same value "fero".

I believe it should save only one value to array.

<?php
add_user_meta(get_current_user_id(),'video_history',"fero");

Hello, @egyptimhotep! Trac is for reporting bugs in WordPress Core, and this is actually a support issue. That being said, try using ​https://developer.wordpress.org/reference/functions/update_user_meta/ instead.

If you have any further issues, try asking over at the support forums ​https://wordpress.org/support/forums/.

Hello @egyptimhotep

This is the expected behaviour. You may either supply en extra parameter $unique and set it to true, or use ´update_user_meta()´. Documented here ​https://developer.wordpress.org/reference/functions/add_user_meta/ and ​https://developer.wordpress.org/reference/functions/update_user_meta/
