Q:

How to read/send post data with php and hold a variable in it

I have this code in a loop in my code, The loop makes one submit button for every member found. I need each button to have the members name stored in it, in a way it can be sent though post when that button is clicked. Im not sure if this is possible with post but i was trying a way i do it with URLS. Does anyone know how to do this?
<input type="submit" value="Attack" name="Attack?name=<?php echo $Member_name; ?>" />

<?php 
if(isset($_POST['Attack'])){
$sql = "SELECT * FROM users WHERE name='".mysql_real_escape_string($_GET['name'])."'";
$query = mysql_query($sql)  or die(mysql_error());
$row = mysql_fetch_object($query);
}

Here is the whole code i was trying to store it in a hidden form but it only grabs the last member found and wont get others.
<?php

$sql = "SELECT name, rank FROM users ORDER BY rank DESC"; //  Searches the database for every one who has being last active in the last 5 minute
$query = mysql_query($sql) or die(mysql_error());
$count = mysql_num_rows($query);
$i = 1;
while($row = mysql_fetch_object($query)) {
 $Member_name = htmlspecialchars($row->name);
$Member_level = htmlspecialchars($row->rank);
?>
<td><?php echo $i; ?></td>
<td><a href="View_Profile.php?name=<?php echo $Member_name; ?>"><?php echo $Member_name; ?></a></td><td><?php echo $Member_level; ?></td><td>
<input type="hidden" name="thename" value="<?php echo $Member_name; ?>">
<input type="submit" value="Attack" name="Attack" />
</td>
<?

 if($i != $count) { // this counts the amount of people that are online and display the results.
  echo "</tr><tr>";
 }
 $i++;
}
?>

<?php 
if(isset($_POST['Attack'])){
$sql = "SELECT * FROM users WHERE name='".mysql_real_escape_string($_POST['thename'])."'";
$query = mysql_query($sql)  or die(mysql_error());
$row = mysql_fetch_object($query);
$profile_id = htmlspecialchars($row->id);
$profile_userip = htmlspecialchars($row->userip);
$profile_name = htmlspecialchars($row->name);
$profile_money = htmlspecialchars($row->money);
$profile_gang = htmlspecialchars($row->gang);
$profile_exp = htmlspecialchars($row->exp);
$profile_profile = htmlspecialchars($row->profile);
$profile_rank = htmlspecialchars($row->rank);
$profile_health = htmlspecialchars($row->health);
$profile_defence = htmlspecialchars($row->defence);
$profile_stanima = htmlspecialchars($row->stanima);
?>

A:

OK, assuming everything else is working ok, and you are retrieving data.  
Change this:  
<input type="hidden" name="thename" value="<?php echo $Member_name; ?>">
<input type="submit" value="Attack" name="Attack" />

To this:
<form method="POST" action="">
<input type="hidden" name="name" value="<?php echo $Member_name; ?>">
<input type="submit" value="Attack" name="Attack" />
</form>

And also in your PHP, change this line: 
$sql = "SELECT * FROM users WHERE name='".mysql_real_escape_string($_GET['name'])."'";

To:
$sql = "SELECT * FROM users WHERE name='".mysql_real_escape_string($_POST ['name'])."'";

This isn't the best way to do this, you will be generating loads of HTML elements depending how many users you have, but it should solve you problem (providing everything else is working and receiving data).
HTML 5 & Javascript would be perfect for this and is something you should look into.
