Answer 1

For one thing, you can put parameter in the form's action attribute, just like you did with the link and href.

More readable option is hidden input element: <input type="hidden" name="offset" value="your_value">

Is this what you asked?

Answer 2

<? echo '<input type=button onclick=\'window.location="companies.php?offset='. $next_offset .'"\'>';?>
