Sorting Alpha and Numeric

Smudly · August 12, 2010

Hi,

I have a page that lists the names of the Artists in one column, and the title of their song in the next column. I've included a sort section that allows users to view the artist (with the corresponding title) that starts with whatever letter they press. I've now come to a point where I need to add in a check for numbers.

(View attached image to understand what we're talking about)

So if the artist name starts with any number between 0-9, it will be shown in order on the page once a user clicks on "#". I've tried doing it various ways, but can't seem to get it just right.

Here is the code (I took out all my attempts to get the numeric sort working):

<?php
session_start();

include_once('inc/connect.php');


if (isset($_SESSION['username'])){
$loginstatus = "logout";
}
else{
$loginstatus = "login";
}
if(!isset($_SESSION['sort_counter']))
{$_SESSION['sort_counter'] = 1;}

if(($_SESSION['sort_counter']%2) == 0){ //test even value
  $sortcount = "DESC";
}else{ //odd value
  $sortcount = "";
}

$result = mysql_query("SELECT * FROM sheets ORDER BY artist");
$sheetscount = mysql_num_rows($result);
$sortletteris = $_GET['letter'];
$downloadclick = $_GET['downloadclick'];
$show = $_GET['show'];
$today = date("Y-m-d");

?>
