How to Sort Columns in Table Views

Firs we need to add a sort option to the Title of the column
 

array_push($td_titles,"140-CLIENT:sort:NAME");

In this example 140 is the width of the column, CLIENT is the title to show and sort:CLIENT indicates that it will sort the table by the column NAME.

Then we need to add the conditional before our query that will modify the order of the results,  $orderby and $asde are predefined variables, in the first part we define our defaults, in this case order by REG_DATE DESC:

if(!isset($ob)){

    $orderby = 'REG_DATE';

    $asde = 'DESC';

}else{

    $orderby = $ob;

}

$query = "SELECT CID, NAME, EMAIL, TEL, REG_DATE FROM $dbtable %%WHERE%% order by $orderby $asde";
