    I want to show defined posts but get_posts shows current post without use definition in args.Why, how to solve it? what is difference between get_posts and wp query? thanks

    ——————————–

    an user on stackoverflow shared this “solution” but it is so fast answer and I couldn’t work it:

    global $post; // This...

foreach ($post_types1 as $post_type1) {
    $post = $post_type1; // ...and this.

    setup_postdata( $post_type1 );

    // etc.
}

wp_reset_postdata();

    ——————————-

    add_action( 'template_redirect', 'check_shop' );
function check_shop()
{
    if (is_shop() ) {
            $args1 = array(
                'post_author' => 'admin',
                'post_type' => 'page',
            );
            $post_types1 = get_posts( $args1, 'objects' );
            foreach ($post_types1 as $post_type1) {
                setup_postdata( $post_type1 );
                if (!empty($post_type1->post_content)) {
                    add_action('woocommerce_before_shop_loop_item_title', function() {
                        global $post_type1;
                        the_title();
                        echo get_the_title($post_type1->ID);
                        echo $post_type1;
                        echo $post_type1->post_content;
                        echo "denemeee yaz?s?";
                    }, 1);
                }
            }
        wp_reset_postdata();
    }
}

    If you’re going to use template tags like the_title(), you must assign the current post in your loop to $post, which you’ve previously declared global. Also use it in the setup_postdata() call. If you don’t, the_title() uses the global $post value from elsewhere.

    get_posts() is essentially a wrapper function for a new WP_Query instance, so there is almost no difference. “almost” because it does do some light interpretation of some arguments. In some rare cases you might get different results.

    your message is not clear for me.can you give working example code with edit my code, it is best answer for me.

    global $post;
$post_types1 = get_posts( $args1, 'objects' );
            foreach ( $post_types1 as $post ) {
                setup_postdata( $post );
                // change all subsequent instances of $post_type1 to $post

    I’d hope you’d understand why as well as have working code. Maybe the More Information section for the setup_postdata() docs page explains it better than I did.

    it is not working on plugin php file or function.php.probably it works on theme template page but not on functions.php.also one developer on google says it is WordPress bug, I don’t know.I changed get_posts with wp_query from plugin PHP file, now, I can see custom query results but also websites under critical error.so, I can’t use website.I tried all WordPress debug commands in wp-config file but WordPress doesn’t write any technic line related my custom query code into log file also WordPress doesn’t show errors on browser even I setted display option on wp-config.Nobody couldn’t help me on debugging issue so I don’t know how can I continue development on this project.

    I’m not sure about your code’s logic, but the code itself, with my modifications should be OK. One exception: echo $post_type1; you can’t echo out a post object. print_r() or var_dump() if you want to examine the entire object. Obviously such output would be for your own investigation, it’s not suitable for production.

    The logic I’m questioning is adding an action callback from within a loop of another action callback. I think by the time ‘woocommerce_before_shop_loop_item_title’ fires, the context of the template_redirect loop will be lost. You might get the final page of the loop at best.

    I’d drop the template_redirect callback and hook ‘woocommerce_before_shop_loop_item_title’ directly, making whatever query and generating whatever output is needed right in the callback.

    Oh, one more minor correction FWIW: get_posts( $args1, 'objects' ); ‘objects’ does nothing. The function only accepts one argument, the $args1 array.
