RE: [PHP] Function to remember costs.[Scanned]

Steve, I've only had a quick glance at this but from the code you've posted you don't seem to be associating a variable with the hidden field you're referring to in the display_form function. You need to store the amount in a variable and then refer to the variable in the value attribute of the hidden field. Michael Egan -----Original Message----- From: Steve Jackson [mailto:stephen.jackson@violasystems.com] Sent: 11 October 2002 11:47 To: PHP General Subject: [PHP] Function to remember costs.[Scanned] I am having difficulty passing details to a form. I need to somehow pass a variable cost to a form. The cost is made up of items in a cart (details taken from a Mysql DB) and a shipping cost. I then have a function written to display the credit card form (which needs to be passed to a secure server below the final cost (ie cost plus shipping). I have tried without success most of this morning to pass the final cost plus shipping to the form hidden field (which is on the same html page!) Here is the section of code I am having problems with. I will supply the rest of the functions to anyone who thinks they can help but it's a lot of code. <? } function display_shipping($shipping) { // display table row with shipping cost and total price including shipping global $total_price; ?> <table border = 0 width = 760 cellspacing = 0> <tr><td align = left>Shipping</td> <td align = right> <?=number_format($shipping, 2); ?></td></tr> <tr><th bgcolor="#146190" align = left>TOTAL INCLUDING SHIPPING</th> <th bgcolor="#146190" align = right>€ <?=number_format($shipping+$total_price, 2); ?></th> </tr> </table><br> <? } function display_card_form($name) { //display form asking for credit card details ?> <table border = 0 width = 760 cellspacing = 0> <form action ='https://spos.luottokunta.fi/pm/servlet/Payment' method='post'> <input type='hidden' name='version' value='1.2'> <input type='hidden' name='merchant_rn' value='8058950'> <input type='hidden' name='order_rn' value='10001'> <input type='hidden' name='amount' value=''> <input type='hidden' name='amount_exp' value='-2'> <input type='hidden' name='currency' value='978'> <input type='hidden' name='order_description' value='Viola test product'> <input type='hidden' name='success_url' value='http://www.violasystems.com'> <input type='hidden' name='failure_url' value='http://www.violasystems.com/bazaar'> <input type='hidden' name='cancel_url' value='http://www.violasystems.com/privacy.php'> <input type='hidden' name='trans_method' value='0'> <input type='hidden' name='mac' value='F529BC531D'> <tr><th colspan = 2 bgcolor="#cccccc">Credit Card Details</th></tr> <tr> <td>Type</td> <td><select name = card_type><option>VISA<option>MasterCard</select></td> </tr> <tr> <td>Number</td> <td><input type = text name = card_number value = "" maxlength = 16 size = 40></td> </tr> <tr> <td>AMEX code (if required)</td> <td><input type = text name = amex_code value = "" maxlength = 4 size = 4></td> </tr> <tr> <td>Expiry Date</td> <td>Month <select name = card_month><option>01<option>02<option>03<option>04<option>05<option>06< option>07<option>08<option>09<option>10<option>11<option>12</select> Year <select name = card_year><option>00<option>01<option>02<option>03<option>04<option>05<o ption>06<option>07<option>08<option>09<option>10</select></td> </tr> <tr> <td>Name on Card</td> <td><input type = text name = card_name value = "<?=$name; ?>" maxlength = 40 size = 40></td> </tr> <tr> <td colspan = 2 align = center> <b>If you press purchase your credit card details will be transmitted via a secure server, your details processed and then you will be redirected to our site.</b> <? display_form_button("purchase", "Purchase These Items"); ?> </td> </tr> </table> <? As you can see the PHP code is just a part of one larger page of functions. What I am trying to do is pass the <?=number_format($shipping+$total_price, 2); ?> to the amount hidden field in the form. Any ideas? This is not all my code which is why I am having problems.
