Hi I am using yui to display a datagrid ...
<?php
$host = "localhost"; //database location
$user = "root"; //database username
$pass = ""; //database password
$db_name = "cms"; //database name
//database connection
$link = mysql_connect($host, $user, $pass);
mysql_select_db($db_name);
//sets encoding to utf8
$result = mysql_query("select dStud_id,dMarkObtained1,dMarkObtained2,dMarkObtained3,dMarkTotal from tbl_internalmarkallot");
//$res = mysql_fetch_array($result);
while($res = mysql_fetch_array($result))
{
//print_r($res);
$JsonVar = json_encode($res);
echo "<input type='text' name='json' id='json' value ='$JsonVar'>";
}
//print_r (mysql_fetch_array($result));
//echo "<input type='text' name='json' id='json' value ='$JsonVar'>";
?>
