Home » Functions » update_user_meta

The "update_user_meta" function in WordPress is used to update a specific meta field for a user in the database. This function is particularly useful if you want to store additional information or data about a user beyond the standard WordPress user fields.

The function takes three parameters:

  1. User ID – the ID of the user whose meta field you want to update.
  2. Meta key – the name of the meta field you want to update.
  3. Meta value – the new value for the meta field.

Here’s an example usage code:

$user_id = 25;
$meta_key = 'favorite_color';
$meta_value = 'blue';

update_user_meta( $user_id, $meta_key, $meta_value );

In this example, we’re updating the "favorite_color" meta field for the user with an ID of 25, and setting the value to "blue". This would update the value of the "favorite_color" meta field in the database for that user.

Overall, the "update_user_meta" function is a powerful tool for customizing and extending the user capabilities of WordPress.
