    Hi @killhunt888,

    I hope you are well today and thank you for your question.

    Is the data stored in fnews database table?

    Can you just write print_r($randomFact); in your code and check whether it displays any data or not?

    Best Regards,

    Hi @killhunt888,

    Thanks for reply.

    I meant if you write print_r($randomFact); then does it display any data on the page? Just copy paste here whatever you see there.

    Are you calling function randomfnews() somewhere? Just write echo 'function calld randomfnews'; in the function randomfnews and tell me is is displaying the message 'function calld randomfnews' ?

    Best Regards,

    Thanks @WPMU DEV
    i got it actually i forgot to call function . I was confused to catch the error sometimes little mistakes causes big tension.
    now it displays random posts
    can you do an extra favor for displaying 7 new recent posts that made recently.
    plz
    thanks a lot

    Hi @killhunt888,

    Thanks for reply.

    You can use following code to display 7 new recent posts but i assume that you have post_date column in wp_fnews table which stores post creation date. if you don't have that column create one and add it's name in following query if it is different name.

    $randomFact = $wpdb->get_results( "SELECT TOP 7 FROM $fnews_table ORDER BY post_date DESC");

    Best Regards,
