linking variable to database

I've made a blog where users can post and make comments on each others' posts. I'd like to make it possible to click on the name of the person who made a post in order to see ALL the posts they have made. In order to do this, my plan was to pass the name of the poster through the URL to the page "personal.php", and then display the posts WHERE the name of the poster matches the name in the field 'Human' in my mysql table. I think I must be going about this all wrong. Help!

Here is the php code for the page so far (it includes a maximum of 10 rows per page stipulation):

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Untitled Document</title>
</head>

<body>

<div style='border-style:solid;
border-width:1px;
width:100px;
bordercolor:white;
cellpadding=:20;
position: absolute;
top: 20px;
left:200px;
width:800px;
text-align: left'>


<?php

$dbh = mysqli_connect("", "", "", "");

$pagenum = $_GET['pagenum'];

if (!(isset($pagenum)))

{

$pagenum = 1;

}

$sql = "SELECT * FROM Posts";

$query = mysqli_query($dbh,$sql);

while($feed = mysqli_fetch_assoc($query))

{

$title = $feed['Title'];

$post = $feed['Content'];

$date = $feed['Date'];

$id = $feed['id'];

$human = $feed['Human'];

$pic = $feed['image_url'];

$pic2 = $feed['image_url2'];

$pic3 = $feed['image_url3'];

$personal = $_GET['human'];

echo "personal $personal$personal$personal/$human";

$sql3= "SELECT * FROM Posts ORDER BY id DESC $max";

$query3 = mysqli_query($dbh,$sql3);

$rows = mysqli_num_rows($query3);

$page_rows = 10;

$last = ceil($rows/$page_rows);

if ($pagenum < 1)

{

$pagenum = 1;

}

elseif ($pagenum > $last)

{

$pagenum = $last;

}

$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;

echo "<a style='text-decoration:none' href='personal.php?human=$human'>$human</a> ";

echo "$date ";

echo "$title \n";

echo " $post \n";

if ( !empty($feed['image_url']) ) {

echo "<img src= '$pic'/> ";

} else {

echo " ";

}

if ( !empty($feed['image_url2']) ) {

echo "<img src= '$pic2'/> ";

} else {

echo " ";

}

if ( !empty($feed['image_url3']) ) {

echo "<img src= '$pic3'/> ";

} else {

echo " ";

}

echo "<div align='right'>";

echo " <a style='text-decoration:none' href='comment1.php?id=$id&Title=$title&Content=$post&Date=$date&image_url=$pic&image_url2=$pic2&image_url3=$pic3&human=$human'>comment on this post </a>\n";

echo " <a style='text-decoration:none' href='delete.php?id=$id&Title=$title&Content=$post&Date=$date&image_url=$pic&image_url2=$pic2&image_url3=$pic3&human=$human'>delete this post </a>\n";

$sql4 = "SELECT comment_id FROM Comments WHERE comment_id=$id";

$query4 = mysqli_query($dbh,$sql4);

if($query4) {

$feed2 = mysqli_fetch_assoc($query4);

$commentid = $feed2['comment_id'];

if ( !empty($feed2['comment_id']) ) {

echo " <a style='text-decoration:none' href='viewcomments.php?id=$id&Title=$title&Content=$post&Date=$date&image_url=$pic&image_url2=$pic2&image_url3=$pic3'> see comments on this post </a>\n";

} else {

echo "no comments yet";

}

echo "</div><hr />";

}

echo "</center>";

echo "<center> Page $pagenum of $last</center>";

if ($pagenum == 1)

{

}

else

{

echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=1'> <center> <<-First </center></a> ";

echo " ";

$previous = $pagenum-1;

echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$previous'> <center> <-Previous </center></a> ";

}

if ($pagenum == $last)

{

}

else {

$next = $pagenum+1;

echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$next'> <center> Next -> </center></a> ";

echo " ";

echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$last'> <center> Last ->> </center> </a> ";

}

echo"</body>

</html>"

?>

</body>

</html>

and here's the link to the page from the main page:

echo "<a style='text-decoration:none' href='personal.php?human=$human'><font style='font-style:italic;font-size:11px' face='Times' align='left'>$human</font></a><br/>";

the 1st div tag u have doesnt appear to be closed</div>, also I would use a userID instead of username as its possible to have users with the same name, if you use a unique autoincrement ID for the user you can link the blog posts and the user to the userID in the user table.
