zang8027 Posted May 13, 2009 Share Posted May 13, 2009 I have an input box called "amount". When the user enters the amount, i need to check what that amount is and send it to paypal. I have three if statements that send the proper amount to paypal: <html> <head></head> <body> <form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post"> AMOUNT: <input type='text' name='amount'/> <input type="hidden" name="business" value="john@lns.com" /> <input type="hidden" name="upload" value="1" /> <input type="hidden" name="lc" value="US" /> <input type="hidden" name="currency_code" value="USD"> <input type="hidden" name="item_name_1" value="$productName" /> <?php //recieve the passed amount $amount = $_POST['amount']; $productName = "Tender Touch Towels"; if($amount > 0) { if($amount <= 1000) { echo ' <input type="hidden" name="quantity_1" value="$amount" /> <input type="hidden" name="amount_1" value="0.19"> '; } } elseif($amount >=1001) { if($amount <=5000) { //post form to paypal with $amount and 0.18 echo ' <input type="hidden" name="quantity_1" value="$amount" /> <input type="hidden" name="amount_1" value="0.18"> '; } } elseif($amount >=5001) { if($amount <=10000) { //post form to paypal with $amount and 0.17 echo ' <input type="hidden" name="quantity_1" value="$amount" /> <input type="hidden" name="amount_1" value="0.18"> '; } } ?> <input type="submit" value="submit" /> </form> </body></html> now without sending this form to a process page and then sending it to paypal, how can i check to see what the user inputed for amount.

radi8 Posted May 13, 2009 Share Posted May 13, 2009 PHP is server side scripting which means that all of the data must be POSTED before the script can run against the value. It appears as though you may need a client side script (javascript) in order to do the client side processing you are looking for. Otherwise, this will need to be posted and then validated.
