[英]How to update WordPress wp_usermeta?
I need to update a single column in wordpress wp_usermeta
.I have gone through the web and I found these codes 我需要更新wordpress
wp_usermeta
的单个列。我已经遍历网络,发现了这些代码
<?php update_user_meta( $user_id, $meta_key, $meta_value, $prev_value ); ?>
Here user_id=1, meta_key=first_name, meta_value="Smith", $prev_value="benny" 在这里,user_id = 1,meta_key = first_name,meta_value =“ Smith”,$ prev_value =“ benny”
How do i write SQL to update the specific column. 如何编写SQL更新特定列。
You don't need to write the SQL, wp gives you that function. 您无需编写SQL,wp为您提供了该功能。
If you are doing a one-off to update the DB, then in your phpmyadmin, you just find the record, and edit it manually; 如果您要一次性更新数据库,则只需在phpmyadmin中找到记录,然后手动进行编辑即可;
if writing PHP, then you use 如果编写PHP,则使用
update_user_meta( $user_id, $meta_key, $meta_value, $prev_value )
ie update_user_meta( 1, 'first_name', 'Smith', 'benny' ) 即update_user_meta(1,'first_name','Smith','benny')
Use below code to update user meta value if it match old meta value 如果与旧元值匹配,请使用以下代码更新用户元值
$user_id = 1;
$meta_key = 'first_name';
$new_value = 'Smith';
$prev_value = 'benny';
update_user_meta( $user_id, $meta_key, $new_value, $prev_value );
