Using 2 while loops to get data from 2 tables - php

Question

I'm trying to get an id from the users database so that I can link to about.php?id=$id1 and I'm using 2 while loops to do that. I end up getting what I want, about.php?id=$id1 but there are duplicate entries...
Here's the code.
<?php
require("connect.php");
require("header.php");
$max = 5; //amount of articles per page. change to what to want
$p = $_GET['p'];
if(empty($p))
{
$p = 1;
}
$limits = ($p - 1) * $max;
//view the news article!
$id = isset($_GET['id']) ? $_GET['id'] : false;
if($id && is_numeric($id)){
$id = $_GET['id'];
$sql = mysql_query("SELECT * FROM blogdata WHERE id = '$id'");
while($r = mysql_fetch_array($sql))
{
echo $total;
$id = $r['id'];
$date = $r['date'];
$title = $r['title'];
$content = $r['content'];
$email = $r['author_email'];
$cat = $r['category'];
$author = $r['author'];
$query1 = mysql_query("SELECT * FROM users");
while ($row1 = mysql_fetch_array($query1)){
$id1 = $row1['id'];
echo "<center>
<table border='0' width='100%' cellspacing='10'>
<tr>
<td width='20%' valign='top'><div class='title'>$title</div>
<div class='info'><i>$date</i><br />
By <a href='$id1'>$author</a><br />
$cat</div>
</td>
<td width='80%' valign='top'>";
echo nl2br($content);
echo "</td>
</tr>
</table>
<hr />
<a href='index'>← Rewind.</a>
</center>";
}
}
}else{
//view all the news articles in rows
$sql = mysql_query("SELECT * FROM blogdata ORDER BY id DESC LIMIT ".$limits.",$max") or die(mysql_error());
//the total rows in the table
$totalres = mysql_result(mysql_query("SELECT COUNT(id) AS tot FROM blogdata"),0);
//the total number of pages (calculated result), math stuff...
$totalpages = ceil($totalres / $max);
while($r = mysql_fetch_array($sql))
{
$id = $r['id'];
$date = $r['date'];
$title = $r['title'];
$content = $r['content'];
$email = $r['author_email'];
$cat = $r['category'];
$author = $r['author'];
$query1 = mysql_query("SELECT * FROM users");
while ($row1 = mysql_fetch_array($query1)){
$id1 = $row1['id'];
echo "<center>
<table border='0' width='100%' cellspacing='10'>
<tr>
<td width='20%' valign='top'><div class='title'>$title</div>
<div class='info'><i>$date</i><br />
By <a href='$id1'>$author</a><br />
$cat</div>
</td>
<td width='80%' valign='top'>";
echo nl2br($content);
echo "</td>
</tr>
</table>
<hr />
</center>";
}
}
//close up the table
echo "</tr></table><center>";
$page = $_GET['p'];
for($i = 1; $i <= $totalpages; $i++)
{
if ( $page == $i ) {
echo "<b>$i</b>";
} else {
echo "<a href='?p=$i'>$i</a>";
}
if ($i < $totalpages)
echo " <font color=\"#666\">•</font> ";
}
}
echo "<br />";
require("footer.php");
?>

Couldn't fully get your question, but does SELECT DISTINCT column_name FROM table help you? It selects only distinct rows from a table.
