Disabling checkout button from shopping cart - php

Answer 1

It looks to me like you're darn close:

if ($rwp >= $total) {    
  echo '<button>Checkout</button>';  //Just put the code you want here
}   
else {
  echo "You do not have enought points to proceed to checkout <br />";
}

In your sample, these lines are in the while which will cause a problem. Just move them out to where you want this to display and you're on your way.

Answer 2

$str = '<tr class="even">
<td colspan="3" align="right"><b> TOTAL:<b></td>
<td align="right"><b>' . number_format ($total) . ' pts </b></td>
</tr>
</table>
<br />
<div align="center"><input type="submit" name="submit" value="Update" />
<input type="hidden" name="submitted"value="TRUE" />
</form><br /><br /></div>
<p><a href="browse_rewards.php"><img src="images/but_continue.png" /></a></p>
<p><a href="submit_cart.php"><img src="images/but_checkout.png" /></a></p>';
if($rwp >= $total) {
 $str .='<a href="submit_cart.php"><img src="images/but_checkout.png" /></a></p>';
}
else {
 $str .='<p>You donnot have enough points to buy</p>'; 
}   
echo $str;

Use the above code instead of the code bellow the following comment in your code

// products the footer, close the table, and the form.
