Question

This is my current code:

$wonAwards = $altdb->get_var("SELECT achievement_id 
                                FROM user_1
                               WHERE isTold='false'");

Currently, $wonAwards is set equal to the first result of the sql query. Is it possible to set $wonAwards equal to an array of all the results of the query?

////////////////// Full Function

function the_header_function(){ //called when wordpress header is loaded
    if (is_user_logged_in()){ //checks if user is logged in
        global $altdb;  //wp global database object
        $user_info = wp_get_current_user();
        $wonAwards = $altdb->query("SELECT achievement_id FROM user_".$user_info->ID." WHERE isTold='false'"); //query
        if(is_array($wonAwards)) $hello='true';
        if(!is_array($wonAwards)) $hello='false';
        if($wonAwards != ''){
            echo "<script>jQuery(document).ready( function(){alert('".$hello."');});</script>";
        }
    }
}

As for checking what the result of my query was, I simply changed this:

echo "<script>jQuery(document).ready( function(){alert('".$hello."');});</script>";

to this:

echo "<script>jQuery(document).ready( function(){alert('".$wonAwards."');});</script>";

Well, according to the Documentation Here, get_var will give you a single result, and query will give you the number of results.

What you really wants (getting all results) can be achieved by the get_results method, so you should write:

$wonAwards = $altdb->get_results("SELECT achievement_id 
                                FROM user_1
                               WHERE isTold='false'");

Try it and tell us if it works, hope that’s helpful.
