[solved] arranging sorted result

i don't know if my subject meets my need here. hehe. i'm quiet new to this thing and done a 'hello world" so far. i wanted to sort a result by asc/desc when sort button is clicked. this is what i've got so far.

PHP Code:

---

<style>
body,table,input{
   font:9pt arial;
}
td,th{
   padding:3px;
}
th{
   color:white;
}
</style>
<?php
   mssql_connect("x","sa","password");
   mssql_select_db("northwind");
   echo"<input type=submit value='sort'><br><br>";
   echo"<table cellspacing=1 bgcolor=#666699 width=100%>";
   echo"<tr><th>ID</th><th>Description</th><th>Region</th></tr>";
   load("select * from territories");
   echo"</table><br>";
   
   function load($s){
      $result=mssql_query($s);
      $i=0;
      while($row=mssql_fetch_array($result,MSSQL_NUM)){
         if($i%2==0) echo"<tr bgcolor=white>";
         else echo"<tr bgcolor=#f4f4f4>";
         foreach($row as $r) echo "<td>$r</td>";
         echo"</tr>";
         $i++;
      }
   }
?>

i don't know how to have the page knowing wether it's asc/desc sort of the result. any help would be greatly appreciated.

The best way to do this is to use a link which reverses the sorty order. You can append a query string to a link refering back to your PHP script and pick up the value from the $_GET array.

You can see a similar method used by these forums. The following link:

The bit after the question mark is the query string. You can then pick up the values of these variables in your PHP script as follows:

PHP Code:

---

$thread = $_GET['threadid'];

I have made a slight modification to your code to enable you to sort.

PHP Code:

---

<?php
  mssql_connect("x","sa","password");
  mssql_select_db("northwind");

  /* get the search order if specified
     1 - is for ascending
     0 - is for descending
   */
  $order = isset ($_GET['order'])?int_val($_GET['order']):1  

  if ($order == 0)
    $orderby = 'ORDER BY [i]ColName[/i] DESC';
  else if ($order == 1)
    $orderby = 'ORDER BY [i]ColName[/i] ASC';
  else
    $orderby = ''; 
?>
<table cellspacing="1" bgcolor="#666699" width="100%">
  <tr>
    <th>ID</th>
    <th>Description</th>
    <th>Region</th>
  </tr>
<?php load("select * from territories $orderby"); ?>
</table>
<a href="<?php echo ($_SERVER['PHP_SELF'] . 'order=' . !$order) ?>">Sort</a>
<?php
   function load($s){
      $result=mssql_query($s);
      $i=0;
      
      while($row=mssql_fetch_array($result,MSSQL_NUM)) {
        if($i%2==0) 
          echo"<tr bgcolor=white>";

        else 
          echo"<tr bgcolor=#f4f4f4>";
  
        foreach($row as $r) echo "<td>$r</td>";
          echo"</tr>";
        
        $i++;
      }
   }
?>
