Displaying Specific Data from mysql database based on user - php

Question

I am trying to have make it so if a user looks at their page they can see the assignments that they have either been working on or have completed. Then I want to make it so that if they look at another users page they can see the projects that they have created.
$my_id = $_SESSION['user_id'];
$frnd_query = mysql_query("SELECT user_one, user_two FROM frnds WHERE user_one = '$my_id' OR user_two = '$my_id'");
while($run_frnd = mysql_fetch_array($frnd_query)) {
$user_one = $run_frnd['user_one'];
$user_two = $run_frnd['user_two'];
if($user_one == $my_id) {
$user = $user_one;
} else {
$user = $user_two;
}
$username = getuser($user, 'username');
echo "<a href = 'my_ideas.php?user=$user' class = 'list' style=display:block>Ideas</a>";
?>
<ul>
<li><a href = '#my_links'>Linked Ideas</a></li>
<li><a href = '#idea_chemistry'>My Idea Chemistry</a></li>
<li><a href = 'settings.php'>Profile Settings</a></li>>
</ul>
</div>
<div id = 'my_projects'>
<?php
if($user != $_SESSION['user_id']) {
$ideas_sql = "SELECT * FROM projects WHERE user_id = $username";
$query = mysql_query($ideas_sql) or die(mysql_error());
$rsIdeas = mysql_fetch_assoc($query);
do {
?>
<h2><a href = 'edit_post.php?id=<?php echo $rsIdeas['id']; ?>'><?php echo $rsIdeas['name']; ?></a></h2>
<?php echo $rsIdeas['keywords']; ?></p>
<p><?php echo $rsIdeas['description']; ?></p>
<?php } while ($rsIdeas = mysql_fetch_assoc($query));
} else {
$ideas_sql = "SELECT * FROM projects WHERE user_id = $my_id";
$query = mysql_query($ideas_sql) or die(mysql_error());
$rsIdeas = mysql_fetch_assoc($query);
do {
?>
<h2><a href = 'edit_post.php?id=<?php echo $rsIdeas['id']; ?>'><?php echo $rsIdeas['name']; ?></a></h2>
<p><?php echo $rsIdeas['keywords']; ?></p>
<p><?php echo $rsIdeas['description']; ?></p>
<?php } while ($rsIdeas = mysql_fetch_assoc($query));
}
?>
<?php
}
?>
I have googled this and searched for related questions on here but I cannot seem to find anything that helps with my problem.

This is basically a code review question. There is also another site on SO network where you could place this type of question. Although you should show that you have some knowledge of coding.
I am not sure why there isn't a starting PHP tag, but here is the first part.
<?php
$my_id = $_SESSION['user_id'];
$frnd_query = mysql_query("SELECT user_one, user_two FROM frnds WHERE user_one = '".$my_id."' OR user_two = '".$my_id."'");
while($run_frnd = mysql_fetch_array($frnd_query)) {
$user_one = $run_frnd['user_one'];
$user_two = $run_frnd['user_two'];
if($user_one == $my_id) {
$user = $user_one;
} else {
$user = $user_two;
}
$username = getuser($user, 'username');
echo "<a href = 'my_ideas.php?user='".$user."' class = 'list' style=display:block>Ideas</a>";
?>
<ul>
<li><a href = '#my_links'>Linked Ideas</a></li>
<li><a href = '#idea_chemistry'>My Idea Chemistry</a></li>
<li><a href = 'settings.php'>Profile Settings</a></li>>
</ul>
<div id = 'my_projects'>
<?php
if($user != $_SESSION['user_id']) {
$ideas_sql = "SELECT * FROM projects WHERE user_id = '".$username."'";
$query = mysql_query($ideas_sql) or die(mysql_error());
$rsIdeas = mysql_fetch_assoc($query);
do {
?>
<h2><a href = 'edit_post.php?id=<?php echo $rsIdeas['id']; ?>'><?php echo $rsIdeas['name']; ?></a></h2>
<?php echo $rsIdeas['keywords']; ?></p>
<p><?php echo $rsIdeas['description']; ?></p>
<?php } while ($rsIdeas = mysql_fetch_assoc($query));
} else {
$ideas_sql = "SELECT * FROM projects WHERE user_id ='".$my_id."'";
$query = mysql_query($ideas_sql) or die(mysql_error());
$rsIdeas = mysql_fetch_assoc($query);
do {
?>
<h2><a href = 'edit_post.php?id=<?php echo $rsIdeas['id']; ?>'><?php echo $rsIdeas['name']; ?></a></h2>
<p><?php echo $rsIdeas['keywords']; ?></p>
<p><?php echo $rsIdeas['description']; ?></p>
<?php } while ($rsIdeas = mysql_fetch_assoc($query));
}
?>
<?php
}
?>
Question: Is this a custom function getuser().
