To get users by a specific ID in WordPress, you can use the WordPress function get_user_by(). This function allows you to retrieve a user object based on a specific field, such as ID.
The syntax for using get_user_by() with ID is as follows:
1
|
$user = get_user_by( 'id', $user_id );
|
Here, $user_id is the ID of the user you want to retrieve.
Once you have fetched the user using the above code, you can access various user information using object properties. For example, to retrieve the user's username, you can use $user->user_login.
However, if you only need to access a few specific properties and not the entire user object, you may consider using the get_userdata() function instead. This function retrieves user data from the database and returns an object with user properties.
The get_userdata() function can be used with ID as follows:
1
|
$user_data = get_userdata( $user_id );
|
After fetching the user data using this function, you can access various user properties using object properties. For example, to retrieve the user's display name, you can use $user_data->display_name.
Remember to replace $user_id with the actual ID of the user you want to retrieve.

How can I get a user's information using their ID in WordPress?
To retrieve a user's information in WordPress using their ID, you can utilize the get_userdata() function. Here's an example of how to accomplish this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
$user_id = 123; // Replace 123 with the actual user ID $user_info = get_userdata($user_id); // Retrieve user data if ($user_info) { // User found, access user information $username = $user_info->user_login; // Username $user_email = $user_info->user_email; // User email $display_name = $user_info->display_name; // Display name // ...and more // Output user information echo "Username: " . $username . "<br>"; echo "Email: " . $user_email . "<br>"; echo "Display Name: " . $display_name . "<br>"; } else { // User not found echo "User not found."; } |
Make sure you replace 123 in $user_id with the actual user ID you want to retrieve information for. You can access various properties of the $user_info object to fetch different details like username, email, display name, and more.
How can I create a shortcode to fetch users by ID in WordPress?
To create a shortcode in WordPress that fetches users by ID, you can follow these steps:
- Open your theme's functions.php file located in your WordPress theme directory.
- Add the following code to create a new shortcode:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
function fetch_user_by_id_shortcode($atts) { $atts = shortcode_atts( array( 'id' => '', // default value if not provided ), $atts, 'fetch_user_by_id' ); $user_id = intval($atts['id']); // convert to integer if ($user_id > 0) { $user = get_user_by('id', $user_id); // fetch the user data if ($user) { return $user->display_name; // return the user's display name, you can modify it as per your requirement } } return 'User not found'; // fallback message } add_shortcode('fetch_user_by_id', 'fetch_user_by_id_shortcode'); |
- Save the functions.php file.
After adding this code, you can use the [fetch_user_by_id id="user_id"] shortcode in your WordPress content or widget areas, replacing user_id with the actual ID of the user you want to fetch. For example, [fetch_user_by_id id="5"] will display the display name of the user with ID 5.
Feel free to modify the shortcode functionality according to your specific needs, such as returning additional user information or formatting the output differently.
What is the function to check if a user with a specific ID exists in WordPress?
The function to check if a user with a specific ID exists in WordPress is get_user_by(). Here's an example of how to use this function:

How to programmatically get users by their ID in WordPress?

In the above example, get_user_by( 'id', $user_id ) searches for a user with the specified ID. If a user is found, it returns the user object, which you can then use to access user data such as their username, email, or any other user meta.
Remember to replace $user_id with the actual ID you want to query.
