我有這樣的代碼來設置定期付款PayPal上PHP的PayPal簡單的API,一次性支付
$p->add_field('cmd','_xclick-subscriptions');
$p->add_field('business','[email protected]');
$p->add_field('item_name', 'Remove Album Release');
$p->add_field('return', $this_script.'?action=success&idAlbum='.$idAlbum.'&package='.$package);
$p->add_field('cancel_return', $this_script.'?action=cancel&idAlbum='.$idAlbum);
$p->add_field('notify_url', 'http://pitchmystuff.com/modules/yobilab/digidist/PayPal/paypal_remove.php');
$p->add_field('no_note','1');
$p->add_field('currency_code','USD');
$p->add_field('a3', "$paymentAmount");
$p->add_field('t3', "Y");
$p->add_field('p3', "1");
$p->add_field('src', "1");
$p->add_field('sra', "1");
我如何改變它與ONE TIME支付工作,而不是重複?
感謝
