If post exists in the database – each time goes on `else`

August 19, 2022 by Tarik Billa

I suspect that PHP considers the value of $wpdb->get_row("SELECT * FROM wp_posts WHERE post_title="" . $title . """, 'ARRAY_A'); to be true no matter what (see also this). You’ll have to count the number of rows that are returned

Try something like this instead:

$query = "SELECT COUNT(*) FROM wp_posts WHERE post_title="$title"";
$count = $wpdb->get_var($query);
return $count > 0;
