Php Private Message reply only functioning on the last row? - php

Question

I am wondering why the code only works on the last row of the message reply, I can't reply on the latest message but I can reply on the last message, the messages are descending.
Please take a look at messages.php:
<form action="read_message.php" method="post">
<div class="pull-right">
<button class="btn btn-info" name="read"><i class="icon-check"></i> Read</button>
Check All <input type="checkbox" name="selectAll" id="checkAll" />
<script>
$("#checkAll").click(function () {
$('input:checkbox').not(this).prop('checked', this.checked);
});
</script>
</div>
<ul class="nav nav-pills">
<li class="active"><i class="icon-envelope-alt"></i>inbox</li>
<li class=""><i class="icon-envelope-alt"></i>Send messages</li>
</ul>
<?php
$query_announcement = mysql_query("select * from message_received
LEFT JOIN user ON user.user_id = message_received.user_id
where message_received.receiver_id = '$session_id' order by date_sent DESC
")or die(mysql_error());
$count_my_message = mysql_num_rows($query_announcement);
if ($count_my_message != '0') {
while ($row = mysql_fetch_array($query_announcement)) {
$id = $row['message_id'];
$id_2 = $row['message_id'];
$fn = $row['firstname'];
$ln = $row['lastname'];
$status = $row['message_status'];
$sender = $row['user_id'];
$sender_name = $fn . ' ' . $ln;
$receiver = $row['receiver_id'];
?><div class="alert alert-info">
<div class="post" id="del<?php echo $id; ?>">
<div class="message_content">
<?php echo $row['content']; ?>
</div>
<div class="pull-right">
<?php if ($status == 'read') {
} else {
?>
<input id="" class="" name="selector[]" type="checkbox" value="<?php echo $id; ?>">
<?php } ?>
</div>
<hr>
Send by: <strong><?php echo $fn . ' ' . $ln; ?></strong>
<i class="icon-calendar"></i> <? php echo $row['date_sent']; ?>
<div class="pull- right">
<a class="btn btn-link" href="#reply<?php echo $id; ?>" data-toggle="modal" ><i class="icon-reply"></i> Reply </a>
</div>
<div class="pull-right">
<a class="btn btn-link" href="#<?php echo $id; ?>" data-toggle="modal" ><i class="icon-remove"></i> Remove </a>
<?php include("remove_inbox_message_modal.php"); ?>
<?php include("reply_inbox_message_modal_user.php"); ?>
</div>
</div>
</div>
<?php }
} else { ?>
<div class="alert alert-info"><i class="icon- info-sign"></i> No Message Inbox</div>
<?php } ?>
</form>
NOW THIS is the function for read_message.php, I can't see any error, please help me.
<?php
if (isset($_POST['reply'])) {
$sender = $_POST['sender'];
$receiver = $_POST['receiver'];
$my_message = $_POST['my_message'];
mysql_query("insert into message_received (user_id,receiver_id,content,date_sent) values('$receiver','$sender','$my_message',NOW())")or die(mysql_error());
mysql_query("insert into message_sent (receiver_id,content,date_sent,user_id) values('$sender','$my_message',NOW(),'$receiver')")or die(mysql_error());
echo "<script> alert('Your message has been sent $my_message') </script>";
echo " <script>location.replace('messages.php')</script>";
?>
<script>
alert('Message Sent');
window.location = "messages.php";
</script>
<?php
}
?>
now this is the reply modal codes,
<!-- Modal -->
<div id="reply<?php echo $id; ?>" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">

You have it your message modal window in one form.
So your solution works only if you have only one message. If you have more messages when you send your response send all responses for each message (its one form) and each response content have same name.
For this reason your server obtains empty $_POST['my_message']
You need have for each response own form and it will works. like this:
<form action="read_message.php" method="post">
<!-- Modal -->
<div id="reply<?php echo $id; ?>" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria- hidden="true">x</button>
<h3 id="myModalLabel">Reply</h3>
</div>
<div class="modal-body">
<center>
<div class="control-group">
<label class="control-label" for="inputEmail">To:</label>
<div class="controls">
<input type="hidden" name="sender" id="inputEmail" value="<?php echo $sender; ?>" readonly>
<input type="hidden" name="receiver" id="inputEmail" value="<?php echo $receiver; ?>" readonly>
<input type="hidden" name="uid" id="inputEmail" value="<?php echo $uid; ?>" readonly>
<input type="hidden" name="my_name" value="<?php echo $reciever_name; ?>" readonly>
<input type="text" name="name_of_sender" id="inputEmail" value="<?php echo $sender_name; ?>" readonly>
</div>
</div>
<div class="control-group">
<label class="control-label" for="inputPassword">Content:</label>
<div class="controls">
<textarea name='my_message'></textarea>
</div>
</div>
<div class="control-group">
<div class="controls">
<button type="submit" name="reply" id="<?php echo $id; ?>" class="btn btn-success reply"><i class="icon-reply"></i> Reply</button>
</div>
</div>
</center>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true"><i class="icon-remove icon-large"></i> Close</button>
<button id="<?php echo $id; ?>" class="btn btn-danger remove" data- dismiss="modal" aria-hidden="true"><i class="icon-check icon-large"></i> Yes </button>
</div>
</form>

PHP variables are not parsed in single quotes. You need to update your SQL queries to use double quotes, or no quotes, with your PHP variables.
insert into message_sent (receiver_id,content,date_sent,user_id) values("$sender","$my_message",NOW(),"$receiver")
That is why only the date is saving.
Clear the messages in your database, update the queries (multiple) and try again. Then, report back with an update and I'll take another look at it.
