How do I script a friend request using php/ajax/jquery? - php

Question

I would appreciate help with this script:
I have this script on a page called members, what I want this script to do is when a member, let's say member A, sends a friends request by clicking the button, first the status changes to something say 'requesting...', then the script sends the request to php via the script this is what I have:
<script type="text/javascript">
var email_cont = '<?=$mem_com[email]?>';
var cont_email = '<?=$_SESSION[email]?>';
$('#connectButton').click(function() {
var counter = 0;
$.ajax({
url: 'requests.php? cont_email='+cont_email+'&email_cont='+email_cont+'&counter='+counter,
success: function( data ) {
$('#connectButton').val(data); // set the button value to the new status.
$('#connectButton').unbind('click');
}
});
});
</script>
For clarity:
the button has a default values called form the database.
cont_email is the email of the member sending request
email_status is the email receiving the request
counter is the request count for every request sent to the members
However, my problem with script is that it only allows for one click on the request button as there are more than one posts from members on the page as it changes the status for all members even when a particular member have not sent any request. ie members A sends request to B, the status should show that request has been sent but however members C login the status of Member A/B request is still display, I want a way to make the status exclusive to each members, status should only show for a particular memeber if request has been sent else the status bears the default value.
Here is my PHP code:
$email_cont = $_GET['email_cont'];
$cont_email = $_GET['cont_email'];
$counter = $_GET['counter'];
$status = "Connection Sent!";
$insert = mysql_query("INSERT INTO reqst VALUES ('','$cont_email','$email_cont','$status', '$counter', NOW())");
if(!$insert) {
//If it fails to run the SQL return an error.
echo "Connection Failed!";
} else {
$update = mysql_query("UPDATE upd SET request ='$status' WHERE email ='$email_cont'");
//If all goes well, return the status
echo $request;
}
I need a way to separate the request made by member A to B from members B to C so that the $update only update the table called upd status for A to B while B and C or C to D maintains the default values as no request is sent yet. so that when the $request is echoed it only carry the request status of the members according to the request status, ie X if request is made, Y if no request is made, Z if request is accepted .

Use jQuery $.get function to send get request to requests.php
$.get('requests.php' , {email_cont: "name#domain.com", cont_email: "name#domain.com", counter: "counter..", function(data){
$('#connectButton').val(data);
$('#connectButton').unbind('click');
});
