You have 2 ways of doing the same :-
1). You can follow this approach also, but the user name will be displayed in the url.
Like:-
http://googl.com/aba.php?name=dinesh
<?
$sql = "SELECT * from members";
$result = mysql_query($sql);
while($row1 = mysql_fetch_array($result)){
echo '<tr>
<td><img src='. $row1['propict'] .' width="70" height="70" /></td>
<td name="frnd" onClick="showUserInfo('$row1[name]')"><a href="fprofile.php">' . $row1['name'] . '</td>';
}
?>
Js function write just below of you code..
function showUserInfo(name) {
window.location= <YOUR BASE URL>+'user_info.php?name='+name;
}
2). The name can also be set in the SESSION by AJAX also. This is a bite long approach but the name will not be displayed in the url.
You need to follow the following steps.
<?
$sql = "SELECT * from members";
$result = mysql_query($sql);
while($row1 = mysql_fetch_array($result)){
echo '<tr>
<td><img src='. $row1['propict'] .' width="70" height="70" /></td>
<td name="frnd" onClick="showUserInfo('$row1[name]')"><a href="fprofile.php">' . $row1['name'] . '</td>';
}
?>
JS function:---
Write the name in session in set_name_in_session.php file, then redirect the control to user_info.php page. There read the user name in user_info.php page and fetch the user details..
function showUserInfo(user_name) {
$.ajax({
url: <BASE_URL_OF_YOUR_SITE>+'set_name_in_session.php', //SET THE SESSION IN THIS FILE
data: {name: user_name},
method:'post',
success:function(response) {
window.location = <BASE_URL_OF_YOUR_SITE>+"user_info.php";
}
});
}

<?
$sql = "SELECT * from members";
$result = mysql_query($sql);
while($row1 = mysql_fetch_array($result)){
echo "<tr><td><img src='. $row1['propict'] .' width='70' height='70' /> </td>";
echo "<td name='frnd'><a href='fprofile.php?name=". $rows['name']. "'>" .
$row1['name'] . '</td>';
}
?>
and in fprofile.php
$_SESSION['name']= $_GET['name'];
now the clicked name is in the variable of $_SESSION['name']
just tell me if there is a syntax error

Update the link so that it passes the name you want to store in the session.
<a href="fprofile.php?name=' . $row1['name'] . '">' .$row1['name'] . '</td>
In fprofile.php, detect if $_GET['name'] has been set, and store it in the session.
if (isset($_GET['name']) && !empty($_GET['name'])) {
$_SESSION['name'] = $_GET['name'];
}
This assumes you are auto starting your session.
You can use $_REQUEST instead of $_GET to handle POST and GET requests similarly.
