Altering upload button PHP/JAVASCRIPT

Hi Guys,

 I am trying to reprogram this wordpress form so it will do two things.

 As of right now, it selects a file using one button and uploads the file using another. I want to make it so when when i click the browse button and select a file, the browse button then changes and says "UPLOAD" allowing for upload.

 Where do i even start?? I have attached my code.

Thanks!

<?php
global $current_user;
 $user_id = get_current_user_id();
$user_last = get_user_meta($user_id);
$unserialize = unserialize($user_last['simple_local_avatar'][0]);

        // ensure no conflicts with existing file names
        $number = 1;
        while ( file_exists( $dir . "/$name$ext" ) ) {
            $name = $base_name . '_' . $number;
            $number++;
        }

I'm not sure that you can change that 'Browse' button because it's built into the browsers to go with <input type="file" name="file">.  It's not something that you program separately.

You can apply some style sheet attributes to the input control, but that's about all.  You cannot access or change the values in the type=file input control.  This is a security issue; the client has 100% of the control over what gets uploaded via an HTML form.

You might be able to do something with a flash animation, but with HTML, it's highly restricted by all modern browsers.
