    Hi!

    I'm trying to save to generate a static json with some wordpress data and metabox fields when a user creates / update a post.

    If I hook 'on_save_post' my json file gets the correct info for wordpress fields, but just the previous for the metabox fields. I guess that with this action metabox fields have not been updated yet, ¿right?

    I have also tried to hook 'rwmb_after_save_post' but I think it doesn't work for me because there are several meta boxes / fields and it doesn't complete the action...

    Is there any action I can use to generate this json when everything is saved?

    Thanks for this great plugin 🙂

    Actually it seems this is not firing when I save a post/page and I change same metabox field value

    add_action( 'rwmb_after_save_post', 'on_save_post_rwmb', 10, 1 );

    it should fire when I update a post or am I missing something?

    Thanks!

    Hi,

    You can follow this documentation to use the action save_post which is fired whenever a post or page is created or updated, include the meta data (field value) saved.

    Try to run the action with the sample code below

    add_action( 'save_post', 'post_published_notification', 999, 3 );

function post_published_notification( $post_id, $post, $update ) {
    echo "This post has been published";
    echo "<br>";
    echo rwmb_meta( $field_id );
    echo "<br>";
    echo "Generate your JSON here";
    die();
}

    Hi Thanks for your response.

    Yes, it was my first idea, but when I do it like that I get wordpress fields correctly updated, but I get the previous value for the metabox field.

    That's why I thought that action save_post fired before metabox update.

    I mean if I save twice then the json get the correct values, but in the first attempt I only get the updated value for a wordpress field

    I have updated the version, just in case, and I have made a minimum test and I don't get the updated value for the metabox field with the example code 🙁

    Is there any work around metabox action where I can get that value field updated??

    Thanks a lot

    Hi,

    After a few hours of researching, I've found a hook to fire after the metadata is saved updated_postmeta, please follow the documentation and the sample code

    add_action( 'updated_postmeta', 'post_published_notification', PHP_INT_MAX, 4 );

function post_published_notification( $meta_id, $post_id, $meta_key, $meta_value ) {
    echo "This post has been published";
    echo "<br>";
    echo rwmb_meta( $field_id );
    echo "Generate your JSON here";
    die();
}

    Please try again and let me know how it goes.

    Thanks Long Nguyen! It works, I can get the metabox field updated in this action 🙂

    The only thing is that I have checked that this action runs not only when you actually save a post, but also when you just load a post entry and you don't make any change. So it is executed much many times than desired, but maybe it's the best we can get at the moment

    Hi,

    You can check the post or other screen by using the function get_current_screen()
    https://developer.wordpress.org/reference/functions/get_current_screen/

    and check it before generating JSON

    function post_published_notification( $meta_id, $post_id, $meta_key, $meta_value ) {
    $screen = get_current_screen();
    if( is_admin() && is_object( $screen ) ) {
        if( $screen->id == 'post' ) {
            echo "This post has been published";
            echo "<br>";
            echo rwmb_meta( $field_id );
            echo "Generate your JSON here";
        }
    }
}
