Multiple submissions with 1 submit button. array?

[rmurp006]

So I am very confused on this one. Heres the deal. I am creating a database for a community and it displays every "friend's profile" that is linked to your own profile. That part works. It displays 3 profile pics per row. I then needed to create checkboxes under each one so once accept friend request was clicked, all the checked pics interacted with the database. That worked. Here is where the problem comes in.

I realized not many people have more then a couple friend requests at a time. So I'd rather display each pic on a different row and I would like each row to have their own accept and deny buttons. I put an array together with a hidden field to gather the values, however when I choose to display the array, it displays all of them. Can I get some help on how to select one value from the array? Some of the code is below.. thank you.

Form button:

<input name='rvalue[]' type='hidden' value='$ffriendid'>
			 <input type='submit' name='Submit3' value='Accept Friend Request'>

PHP Portion:

if($_POST['Submit3']){
    $rvalue2 = $_POST['rvalue'];
    array_map('intval',$rvalue2);
    $rvalue2 = implode(',',$rvalue2);
    mysql_query("UPDATE friendslist SET status='active' WHERE friend_id IN ($rvalue2) && user_id='$userid' || user_id IN ($rvalue2) && friend_id='$userid'") or trigger_error(mysql_error(),E_USER_ERROR);
}

Thanks again for any help..

IF you want to submit them separately, put each image and submit button in a separate form. But why not let the user deal with all at requests at once anyway, along the lines of
Form

<form ...>
	<div>
		<img ... />
<?php
		# $user_id would probably come from a while loop accessing database rows
		echo '<input type="radio" name="uid_'.$user_id.'[]" value="accept" />';
		echo '<input type="radio" name="uid_'.$user_id.'[]" value="refuse" />';
?>
	</div>
	<div>
		<img ... />
<?php
		# different user_id from above
		echo '<input type="radio" name="uid_'.$user_id.'[]" value="accept" />';
		echo '<input type="radio" name="uid_'.$user_id.'[]" value="refuse" />';
?>
	</div>
	<div>
		<input type="submit" name="update_friends" value="Update Friends" />
	</div>
</form>

Form processing

if (!empty($_POST['update_friends'])) {
	foreach($_POST as $k => $v) {
		if (preg_match('#uid_(\d+)#', $k, $match)) {
			# $id is id of user who sent friend request
			$id = $match[1];

		# $v is 'accept' or 'refuse'. Let $user be the user submitting the form
		handleFriendRequest($user, $id, $v);			
	}
}
}

# In reality it might be smarter to change the above like this
# and let handleFriendRequest deal with looping over post data.
if (!empty($_POST['update_friends'])) {
	handleFriendRequest($user, $_POST);
}
