I want to redirect to a page using a <button> tag.. however, it's not working
<?php $url2 = "mission_schedule.php?id=" . urlencode($_GET['id']);?>
    <!-- this is not working -->        
    <button onclick=location.href='<?php echo $url2; ?>'; >Next</button>
    <!-- this is working -->           
    <a href="<?php echo $url2;?>">Next</a>
clicking the button reloads the same page.. while clicking the link redirects me to the right page In addition, this button works in other pages normally
