Tried to do it with general wordpress posts and simplier code… still writes the file only after I press the ‘update’ button the second time

function opt_update($ID, $post) {
    $args = array(
        'post_type' => 'post'
    );
    $opt_array = array();
    $the_query = new WP_Query($args);
    while ($the_query -> have_posts()): $the_query -> the_post();
    array_push($opt_array, array(
        'price' => get_field('price')
    ));
    endwhile;
    wp_reset_postdata();
    file_put_contents($_SERVER['DOCUMENT_ROOT'] . '/wp-content/themes/blablabla/json/data.json', raw_json_encode($opt_array));
}
add_action('publish_post', 'opt_update', 10, 2);

Thanks Navneil, but can’t find solution in the articles… tried to do it with ‘transition_post_status’, but everything is the same

<?php
add_action('transition_post_status', function($new_status, $old_status, $post)
{

    if ('publish' == $new_status && $post->post_type == 'opt') {

        $args      = array(
            'post_type' => 'opt'
        );
        $opt_array = array();
        $the_query = new WP_Query($args);
        sleep(3);
        while ($the_query->have_posts()):
            $the_query->the_post();
            $good_type_array = array();
            while (have_rows('good_type')):
                the_row();
                $good_type_name = get_sub_field('good_type_name');
                array_push($good_type_array, $good_type_name);
            endwhile;
            array_push($opt_array, array(
                'name' => get_the_title(),
                'good_type' => $good_type_array,
                'price' => get_field('price')
            ));
        endwhile;
        wp_reset_postdata();
        file_put_contents($_SERVER['DOCUMENT_ROOT'] . '/wp-content/themes/blablabla/json/data.json', raw_json_encode($opt_array));
    }
}, 10, 3);
?>
