Is it possible to scope a submit with html/php? - php

Question

I have a form wrapped table with many repeating rows. The table's purpose is to allow editing of user accounts. Each row look like this:
<tr>
<td><input type="text" name="username" value="$row->username" /></td>";
<td><input type="text" name="fname" value="$row->fname" /></td>
<td><input type="text" name="lname" value="$row->lname" /></td>
<td><input type="email" name="email" value="$row->email" /></td>
<td><button type="submit" class="btn btn-primary" name="edituserbutton" value="$row->id" >Edit</button>";
</tr>
I build this table. I can change the names of each of the input elements, on a row
to row basis, so that they are made unique; name="username##" where ## = $row->id.
But I was wondering if the post could be scoped somehow to the row. I'm trying
to avoid having to build keys like this
$id = $_POST['edituserbutton'];
$user_name = $_POST['username'.$id];
Is this possible?
And also, concerning the presentation and editing of data, is this how it's generally done?
=========== update
Here's what I did. Works great. Thank you all:
$(document).ready(function() {
$('button[name=edituserbutton]').click(function(e) {
e.preventDefault();
var buttonvalue = $(this).attr("value");
alert("button value is " + buttonvalue);
// .. business here
return;
})
});

<tr>
<td><input type="text" name="username[$row->id]" value="$row->username" /></td>";
<td><input type="text" name="fname[$row->id]" value="$row->fname" /></td>
<td><input type="text" name="lname[$row->id]" value="$row->lname" /></td>
<td><input type="email" name="email[$row->id]" value="$row->email" /></td>
<td><button type="submit" class="btn btn-primary" name="edituserbutton" value="$row->id">Edit</button>";
</tr>
Then, in PHP
$id = $_POST['edituserbutton'];
$newUserName = $_POST['username'][$id];
If you also want to avoid submitting a lot of redundant data, you'll want to make each row a form on its own, like
<tr>
<form action="...">
<td><input type="text" name="username" value="$row->username" /></td>
<td><input type="text" name="fname" value="$row->fname" /></td>
<td><input type="text" name="lname" value="$row->lname" /></td>
<td><input type="email" name="email" value="$row->email" /></td>
<td>
<button type="submit" class="btn btn-primary" name="edituserbutton">Edit</button>
<input type="hidden" name="rowId" value="$row->id"/>
</td>
</form>
</tr>
