Unable to find the solution help me out ..regarding js and php - php

Question

php code :
while($row = mysql_fetch_assoc($arr))
{
$id = $row['id'];
$user_from = $row['user_from'];
$user_to = $row['user_to'];
$date = $row['date'];
$msg_body = $row['msg_body'];
$opened = $row['opened'];
if(strlen($msg_body)>150)
{
$msg_body = substr($msg_body,0,150)."....";
}
echo "<div id='toggletext$id' style='background-color:#ADD8E6;padding:6px;' onclick='toggle()'>";
echo "<form method='post'>";
echo "<input type='hidden' id='id1' value=$id>";
echo "<a href='$username'>$username</a>&nbsp";
echo "&nbsp: $msg_body ";
echo "</form>";
echo "</div> <hr/>";
}
** it will echo the value present in $arr in forms of div so each $arr row will get displayed with unique div id **
js code :
function toggle()
{
var hr = new XMLHttpRequest();
var id = document.getElementById("id1").value;
var tx = "toggletext"+id;
var fn = document.getElementById(tx);
var url = "in.php";
fn.style.backgroundColor = "#fff";
var v = '<?php echo #$username;?>';
var vars = "post="+v+"&id="+id;
hr.open("POST", url, true);
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
hr.onreadystatechange = function()
{
if(hr.readyState == 4 && hr.status == 200)
{
var return_data = hr.responseText;
document.getElementById("status").innerHTML = return_data;
}
}
hr.send(vars);
document.getElementById("status").innerHTML = "processing...";
}
// The problem is ...when there are 2 div(if $arr has 2 rows)..if i click the second div first div will get selected ..

Answer 1

Change your id in your input type hidden
echo "<input type='hidden' id='id".$id."' value=$id>";
and get like this in your javascript...
var incval = '<?php echo $id ?>';
var id = document.getElementById("id"+incval).value;
I am giving php echo because you already call username....
Finally, try to use My_Sqli function instead my_sql
