Question

I have try to get answer from WordPress Answer but instead of getting answer I earn Thmbleweed badge. 🙁 anyways so I am trying here and hopping solution.

My new website going to have multiple author. All I need to do with that some specific system where Admin can add banner to the specific author’s post.

Fore example xxx banner will only display on xyz author’s post and not on any other author post. Which will have auto expiry system, it will automatically invisible when it reach to defined date by admin. All these systems will be under admin control only.

I am not php guy but can play with wordpress codes a bit. So I need really great help to work this out. I also won’t mind to give full credit on my website credit display for this system.

Answer 1

Create a table with fields:id, authorid, banner_content, expiry_date.

To fill in the table with specific details of authorid,
banner_content, expiry_date create a simple form or directly enter in
the database.

After your table is created and is filled with details

HERE IS THE COMPLETE CODE TO DISPLAY THE BANNER

    <?php 
    $getid = $posts[0]->post_author; //No need to change this
    $sql= "SELECT * FROM bannertable wbanner WHERE author_id = $getid AND expiry_date>CURDATE();"; //change the table name 'bannertable' and field names 'author_id' and 'expiry_date' to your own
    $banner_con=$wpdb->get_results($sql);
    echo "<div class='banner'>";
    foreach ( $banner_con as $content ) 
    {
        echo $content->banner; //change field name 'banner'.
    }
    echo "</div>
    ?>

Make sure to enter the above code inside the loop of your theme.
