no, i mean that on the searchpage.php page, yoou will have behaivors that use the button as a trigger:
something like:
if(isset($_GET['SEARCH'])) {
use the text box as the trigger instead:
if(isset($_GET['name'])) {
also, the button should have a name and value attribute:
<button type="submit" name="SEARCH" value="SEARCH">SEARCH</button>
