Hyperlink Post using Php

Hi guys, creating a "who's online" module for my project where I can view the user's profile when online. I'm able to view whose online now, but no matter who I click, it would only display the last person's information.

From my understanding, this line of code needs some editting which I'm not really sure about doing it.


echo '<a href ="#" onclick="document.formname.submit(); return false;">'
.$row2['uname'].'<input name="friendName" type="hidden" value="'.$row2["uname"].'" /></a> ,';

I spent a whole afternoon trying to find an appropriate solution but could not solve my problem still. I managed to post information from my main page to the second page but however it only obtains the last information when I retrieve it on the second page.

How do I get the correct information I want ? My codes are below

<?PHP 
//session_start();
include ('conn.php');
include ('time.php');

echo '<br>
<form name="formname" method="POST" action="friendProfile.php">';

$query5 ="select uname from online where online='1'";
$result5 = mysql_query($query5) or die('Query failed: ' . mysql_error());
	if (!$result5) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}//echo 'users online....';
$num = mysql_numrows ($result5);

if($num ==1){
while ($row2 = mysql_fetch_assoc($result5)) {

echo '<a href ="#" onclick="document.formname.submit(); return false;">'.$row2['uname'].'<input name="friendName" type="hidden" value="'.$row2["uname"].'" /></a> ,';

}echo ' is online.';

}else if($num ==0){
echo 'Nobody is online.';

	}else{	
			while ($row2 = mysql_fetch_assoc($result5)) {

echo '<a href ="#" onclick="document.formname.submit(); return false;">'.$row2['uname'].'<input name="friendName" type="hidden" value="'.$row2["uname"].'" /></a> ,';

	}echo ' are online.';}
echo '</form>';
?>

You've got all these hidden form fields, all with the same name, all in the same form. When you submit that form all of those fields will be submitted. Chances are, only the last will be retained.

I'm going to guess you only want one of those names anyway.

<form id='formname' name='formname'><input type='hidden' id='friendName' name='friendName' /></form>
<script type="text/javascript">
// This is just for abbreviation in the link.
var frm = document.getElementById('formname');
var fld = document.getElementById('friendName');
</script>
....loop begins
<a href='#' onclick='fld.value="<?php echo $row2['uname'] ?>"; frm.submit();'>blah blah</a>
....loop ends

The alternative would be to wrap every single link in its own form, or have the link construct a form object, construct a field and insert it into the form, set the value of the field, then submit the form. That could be done either inline in every link, or as a Javascript function call.

Its rather confusing as I'm using SQL to store values 1 and 0 for people that goes online. When one goes online, in the SQL it will update the value to 1.

I have to read the database in order to find out who is "online" so now my codes above are to read from database and display on the webpage. So if I have 5 people online , all 5 would be shown on the webpage, when I click on their name. It should bring me to their profile page. But my codes that I did only allows me to capture the last value which is the 5th person instead of 1st to 4th.

I tried to post in the form with hidden values but I am unable to catch it on the other webpage. Thus its rather frustrating. Having the submit button would solve that problem but its too ugly !!
