I'm trying to get latest post ID.

And then store that ID into user_meta.

Right now I have this code:

add_action('wp', 'bt_update_user_homepage_meta');
function bt_update_user_homepage_meta () {
// Get user id
$user_id = get_current_user_id();

// Get newest post ID
        //WP_Query Arguments
$args = array(
    'posts_per_page'    => 1,
    'meta_key'          => 'usp-custom-1',
    'meta_value'        => 'question',

//Execute WP_Query (Results placed in $the_query)
$the_query = new WP_Query($args);
$id = get_the_ID();
//The WordPress Loop
if ($the_query->have_posts()) { //Check if there are any posts returned in $the_query

    while ($the_query->have_posts()) { //Loop through posts returned in $the_query

//Update user meta with the latest post ID
         if ( is_page( array( 'home' ) ) ) update_user_meta($user_id, 'pagehome', $id);


//Reset WordPress Post Data

But it stores current post ID, instead of the latest post ID.

Been struggling with this for a while.

I know I maybe missing something in the code.

Need help.

    $id = get_the_ID(); is outside the loop. It needs to be after $the_query->the_post() to get the ID of the post inside the query. Commented Jul 14, 2021 at 14:05
  • You should also elaborate on what you're ultimately trying to achieve. Writing to the database on every request is not a good idea. Commented Jul 14, 2021 at 14:06
  • Brilliant! it worked simply by putting $id = get_the_ID(); inside the query! Thanks Jacob. I thought I was missing something very small. I have also used if ( !empty( $user_id ) && is_page( [ 'home' ] ) ) to process only logged in users. THANKS AGAIN!

Here is the code that should probably work for you:

function bt_update_user_homepage_meta() {

    // Get user id
    $user_id = get_current_user_id();

    if ( !empty( $user_id ) && is_page( [ 'home' ] ) ) {

        $posts = wp_get_recent_posts( array(
            'numberposts' => 1,
            'meta_key'    => 'usp-custom-1',
            'meta_value'  => 'question'
        ) );

        if ( !empty( $posts ) ) {
            update_user_meta( $user_id, 'pagehome', array_pop( $posts )->ID );

add_action( 'wp', 'bt_update_user_homepage_meta' );

I've tweaked things:

  • I've wrapped it up in the if ( !empty( $user_id ) && is_page( [ 'home' ] ) ) so that you don't do any of this processing unless the user is logged-in and it's the page "home"
  • I use the handy wp lookup function wp_get_recent_posts for recent posts that orders them by the newest published, and limit the query to 1 result.
  • then I pop it off the array of posts and reference the ID to store it into the user meta.

For completeness sake, I should say that you probably shouldn't be doing this on every time the page is loaded as you'll have that extra get_posts() query each time, albeit for only logged-in users. There isn't really an issue with updating the user meta though, since if the value isn't changed, no data is written to the DB.

  • Hey Paul G, thanks for your effort, I have actually fixed my code simply putting the $id = get_the_ID(); inside the query and used your if ( !empty( $user_id ) && is_page( [ 'home' ] ) ) so that only logged in users on the page "home" would be proccessed. THANKS AGAIN for your time!
