Hoe los ik dit op?

Hallo

Ik ben momenteel aan het werken aan een website. Ik biedt er op 1 bepaalde pagina meerdere dingen te koop aan.
Betalen kan via e-gold.

Om dit te doen kan volgende code gebruikt worden:

<form action="https://www.e-gold.com/sci_asp/payments.asp"; method="POST" target=_top>
<div align="center">
<input type="hidden" name="PAYEE_ACCOUNT" value="XXXXXX">
<input type="hidden" name="PAYEE_NAME" value="Put Your Company name here">
Enter Amount You'd like to Donate:<br>
<input type=text name="PAYMENT_AMOUNT" size=4>
<input type=hidden name="PAYMENT_UNITS" value=1>
USD worth of e-gold
<input type=hidden name="PAYMENT_METAL_ID" value=1>
<input type="hidden" name="STATUS_URL" value="mailto:YourEmailAddress@YourDomain">
<input type="hidden" name="NOPAYMENT_URL"
value="http://www.e-gold.com/unsecure/sci_home.html">;
<input type="hidden" name="NOPAYMENT_URL_METHOD" value="LINK">
<input type="hidden" name="PAYMENT_URL"
value="http://www.e-gold.com/unsecure/sci_home.html">;
<input type="hidden" name="PAYMENT_URL_METHOD" value="LINK">
<input type="hidden" name="BAGGAGE_FIELDS" value="CUSTOMERID">
<input type="hidden" name="CUSTOMERID" value="0">
<input type="hidden" name="SUGGESTED_MEMO" value='Thanks for paying with e-gold!'>
<br>
<input type="submit" name="PAYMENT_METHOD" value="Donate Now">
</div></form>

Ik zou echter slechts 1 betaalknop willen (dus niet bij elke object 1).

Ik zou dit via een selectbox doen (of hoe heet zo'n ding; ik ken eigenlijk niet veel van php of html).

Het zou dus als volgt gaan dan:

<form name="submit-egold" action="https://www.e-gold.com/sci_asp/payments.asp"; method="post" target="_blank">
<select class=input1 name="PAYMENT_AMOUNT" size="1">
<option>Choose:</option>
<option value="GELDBEDRAG1">ITEM1</option>
<option value="GELDBEDRAG2">ITEM2</option>
enz...
</select>
<input type="hidden" name="PAYEE_ACCOUNT" value="XXXXXX">
<input type="hidden" name="PAYEE_NAME" value="Put Your Company name here">
Enter Amount You'd like to Donate:<br>
<input type=hidden name="PAYMENT_UNITS" value=1>
USD worth of e-gold
<input type=hidden name="PAYMENT_METAL_ID" value=1>
<input type="hidden" name="STATUS_URL" value="mailto:YourEmailAddress@YourDomain">
<input type="hidden" name="NOPAYMENT_URL"
value="http://www.e-gold.com/unsecure/sci_home.html">;
<input type="hidden" name="NOPAYMENT_URL_METHOD" value="LINK">
<input type="hidden" name="PAYMENT_URL"
value="http://www.e-gold.com/unsecure/sci_home.html">;
<input type="hidden" name="PAYMENT_URL_METHOD" value="LINK">
<input type="hidden" name="BAGGAGE_FIELDS" value="CUSTOMERID">
<input type="hidden" name="CUSTOMERID" value="0">
<input type="hidden" name="SUGGESTED_MEMO" value='Thanks for paying with e-gold!'>
<br>
<input type="submit" name="PAYMENT_METHOD" value="Donate Now">
</form>

de input voor payment_amount is dus niet meer nodig.

Ik wil nu echter ook dat de suggested_memo automatisch de naam is van het item dat geselecteerd is.

HOE DOE IK DAT??

Alvast bedankt
Robin
