This is How to Update User Meta with Spaces Using the WordPress REST API
As a WordPress developer, you may often need to update user meta data, which can include fields with spaces. Updating user meta with spaces can be a bit tricky, as the WordPress REST API doesn't handle spaces in field names very well. In this article, we'll explore a few techniques you can use to successfully update user meta with spaces using the WordPress REST API.
Understand the Challenge of Updating User Meta with Spaces
When you try to update user meta with spaces using the WordPress REST API, you may encounter issues. The REST API expects field names to be URL-encoded, but this can cause problems when you have spaces in the field names.
For example, let's say you have a user meta field called "First Name". If you try to update this field using the REST API, the request may look something like this:
POST /wp-json/wp/v2/users/1/meta
{
"First Name": "John"
}
However, this will not work because the REST API expects the field name to be URL-encoded, which would look like this:
POST /wp-json/wp/v2/users/1/meta
{
"First%20Name": "John"
}
Use HTML Entities to Update User Meta with Spaces
One way to overcome the issue of updating user meta with spaces is to use HTML entities to represent the spaces. HTML entities are special codes that represent certain characters, and they can be used in the field names to bypass the REST API's URL encoding requirements.
Here's an example of how you can use HTML entities to update user meta with spaces:
POST /wp-json/wp/v2/users/1/meta
{
"First Name": "John"
}
In this example, we've used the HTML entity
to represent the space in the "First Name" field name. This should allow the REST API to update the user meta successfully.
You can also use other HTML entities to represent different characters, such as &
for the ampersand (&
) and "
for double quotes ("
).
Use URL Encoding to Update User Meta with Spaces
Another approach to updating user meta with spaces is to use URL encoding. This involves manually encoding the field names using a function like urlencode()
or rawurlencode()
before sending the request to the REST API.
Here's an example of how you can use URL encoding to update user meta with spaces:
POST /wp-json/wp/v2/users/1/meta
{
"First%20Name": "John"
}
In this example, we've manually encoded the "First Name" field name using the urlencode()
function, which replaces the space with the %20
character.
You can also use the rawurlencode()
function, which is a bit more strict and may be preferred in some cases:
POST /wp-json/wp/v2/users/1/meta
{
"First%20Name": "John"
}
Combine HTML Entities and URL Encoding
In some cases, you may need to use a combination of HTML entities and URL encoding to successfully update user meta with spaces. This can be useful if you're working with field names that contain both spaces and other special characters.
Here's an example of how you can combine these techniques:
POST /wp-json/wp/v2/users/1/meta
{
"First%20 Name": "John"
}
In this example, we've used both URL encoding (for the space) and an HTML entity (for the additional space) to create a field name that should work with the WordPress REST API.
Use the implode()
Function to Simplify the Process
To make the process of updating user meta with spaces a bit easier, you can use the implode()
function in PHP to combine the field name and value into a single string. This can help you avoid having to manually construct the JSON payload for the REST API request.
Here's an example of how you can use implode()
to update user meta with spaces:
$meta_key = 'First Name';
$meta_value = 'John';
$meta_data = array(
rawurlencode($meta_key) => $meta_value
);
$response = wp_remote_post(
'/wp-json/wp/v2/users/1/meta',
array(
'body' => json_encode($meta_data),
'headers' => array(
'Content-Type' => 'application/json'
)
)
);
In this example, we use the rawurlencode()
function to encode the field name before adding it to the $meta_data
array. This allows us to easily create the JSON payload for the REST API request without having to manually construct the field name.

Real-World Example: Updating User Meta with Spaces in a WordPress Plugin
Let's say you're building a WordPress plugin that needs to update a user's "Favorite Color" meta field. Here's an example of how you could implement this functionality using the techniques we've discussed:
function update_favorite_color() {
// Get the current user ID
$user_id = get_current_user_id();
// Get the new favorite color from the request
$new_color = sanitize_text_field($_POST['favorite_color']);
// Update the user meta
$meta_key = 'Favorite Color';
$meta_value = $new_color;
$meta_data = array(
rawurlencode($meta_key) => $meta_value
);
$response = wp_remote_post(
"/wp-json/wp/v2/users/$user_id/meta",
array(
'body' => json_encode($meta_data),
'headers' => array(
'Content-Type' => 'application/json'
)
)
);
if (is_wp_error($response)) {
// Handle the error
$error_message = $response->get_error_message();
// ...
} else {
// Success!
// ...
}
}
In this example, we first get the current user's ID, then we sanitize the new favorite color value from the request. We then construct the $meta_data
array using the rawurlencode()
function to encode the "Favorite Color" field name. Finally, we use the wp_remote_post()
function to send the update request to the WordPress REST API.
By using the techniques we've discussed in this article, you can ensure that your WordPress plugin or application can successfully update user meta with spaces, even when using the WordPress REST API.
In summary, the key techniques for updating user meta with spaces using the WordPress REST API are:
- Use HTML entities to represent spaces in the field names.
- Use URL encoding (e.g.,
urlencode()
or rawurlencode()
) to encode the field names.
- Combine HTML entities and URL encoding for more complex field names.
- Use the
implode()
function to simplify the process of constructing the REST API request.
By implementing these techniques, you can ensure that your WordPress applications can effectively manage user meta data, even when dealing with fields that contain spaces.
