HTML Form Basics for PayPal Payments Standard custom fields - forms

Question

I'm trying to put a PayPal form on my website but I would also like to put custom fields on it.
I mean, I would like to receive the details that maybe are different from the PayPal details.
Maybe someone does a payment but wants to use a PayPal account with a different email, so I would like to know both the emails.
I would like to create a form with these fields:
First name
Last name
Personal email (not Paypal email)
and I want to be able to see these information when I receive the payment.
This is my form:
<div id="paynow" class="contact_form_invoice_payment">
<div class="invoice_payment_title">Pay your invoice here</div>
<form method="post" action="https://www.paypal.com/cgi-bin/webscr">
<input value="_xclick" name="cmd" type="hidden">
<input value="nessa#stressless.ie" name="business" type="hidden">
<input value="http://www.matrix-test.com/stressless/" name="return" type="hidden">
<input value="0" name="no_shipping" type="hidden">
<input value="1" name="no_note" type="hidden">
<input value="EUR" name="currency_code" type="hidden">
<input value="IE" name="lc" type="hidden">
<input value="PP-BuyNowBF" name="bn" type="hidden">
<input value="0" name="tax" type="hidden">
<input value="Online Payment" name="item_name" type="hidden">
<input value="OP" name="item_number" type="hidden">
<div class="first_name_invoice_payment">
First name (requiered) <br />
<input value="" name="first_name">
</div>
<div class="last_name_invoice_payment">
Last name (requiered)<br />
<input value="" name="last_name">
</div>
<div class="email_invoice_payment">
Email (requiered)<br />
<input value="" name="email">
</div>
<div class="first_name_invoice_payment">
Invoice Number (requiered)<br />
<input id="inv" value="" name="item_number">
</div>
<div class="last_name_invoice_payment">
Amount - Euro Only (requiered)<br />
<input id="amt" value="" name="amount">
</div>
<div class="job_title_invoice_payment">
<input alt="PayPal - The safer, easier way to pay online!" name="submit" border="0" src="https://www.paypal.com/en_US/i/btn/btn_paynowCC_LG.gif" type="image" class="no-width image" style="width:auto !important; border:none; margin-top:20px;">
<img height="1" width="1" src="https://www.paypal.com/en_US/i/scr/pixel.gif" border="0" alt="">
</div>
</form>
</div>
I tried to put these fields:
name="first_name"
name="last_name"
name="email"
but I can't see them in the PayPal email and even in the PayPal backoffice.

Answer 1

Try using the variables below to gather the information you are looking for:
on0 = CustomerName
os0 = "Enter First and Last Name"
on1 = CustomerEmail
os1 = "Enter Email Address"
Developer: https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/Appx_websitestandard_htmlvariables/
Your updated code would look similar to this:
<input value="CustomerName" name="on0" type="hidden">
<input value="CustomerEmail" name="on1" type="hidden">
<div class="first_name_invoice_payment">
First/Last name (requiered) <br />
<input value="" name="os0">
</div>
<div class="email_invoice_payment">
Email (requiered)<br />
<input value="" name="os1">
</div>
