Function Name: get_user_meta
WordPress is a powerful content management system that offers a wide range of functions to developers. One of the most important functions in WordPress is get_user_meta(), which is used to retrieve metadata for a specific user.
Metadata is essentially additional information that is attached to a user profile. It can be used to store any type of information, such as a user’s location, preferences, or any other custom information that is important for your website. get_user_meta() helps you retrieve this information when you need it.
The function takes two parameters: the user ID and the name of the metadata key. If the key doesn’t exist, the function will return an empty string.
Here’s an example of how to use get_user_meta():
$user_id = 123;
// Retrieve user meta for the ‘location’ key $location = get_user_meta($user_id, ‘location’, true);
// Output the location value echo ‘User location: ‘ . $location;
In this example, we retrieve the ‘location’ metadata for the user with ID 123. The third parameter of the function is set to true, which means that we want to retrieve a single value rather than an array of values. Finally, we output the location value using echo.
Overall, get_user_meta() is a powerful function that can help you retrieve important user information for your WordPress website.
