Need help with modifying values

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The first script works ' modify_values.php' showing the values and a modify 
link next to each but the next script it parses to  'modify_values2.php' is 
obviously not working. I have tried to modify it from another script and 
cant get it to pass the correct variables-- it always shows the first row in 
the database . Any help appreciated.

modify_values.php

<?php
include("connect.php");
$sql = "Select * from leaderboard";
$result = mysql_query($sql);
?>

<body bgcolor="#FFFFFF" text="#666666" link="#666666">


<table width="461" border="1" align="center" cellpadding="2" cellspacing="0" 
bordercolor="#FFFFFF" bgcolor="#FFFFFF">
<tr>
 <td width="206" height="25" align="center" bordercolor="#FFFFFF" ><div 
align="left"><b>Title</b></div></td>
 <td width="165" align="center" bordercolor="#FFFFFF" bgcolor="#FFFFFF"><div 
align="left"><b>Rating</b></div></td>
 <td width="70" align="center" bordercolor="#FFFFFF" bgcolor="#FFFFFF"></td>

</tr>
<?php
while ($myrow = mysql_fetch_array($result)) {

 echo "<tr><td>" . $myrow['Name'] . "</td>";
 echo "<td>" . $myrow['Rating'] . "</td>";
 echo "<td bgcolor='cyan'> <a href='modify_values2.php?id=" . $myrow['ID'] . 
"'>Modify</a></td></tr>";
}
?>
</table>
