php - Passing data to paypal IPN using option_select -
i have question passing paypal data form ipn.
what i'm trying making select field different options donator can choose from. , every option needs handled differently in ipn.
since prices same, handling different on every item cannot use code anymore
$amount = $p->ipn_data['mc_gross'] - $p->ipn_data['mc_fee']; $donateamount = 5; $donateamount2 = 10; if($amount == $donateamount){ //custom code } if($amount == $donateamount2){ //custom code } etc........ here example current form code:
<html> <head> </head> <body> <?php // paypal enchant donation option list echo '<form action="'.$paypalurl.'" method="post" class="paypalform">'; echo '<input type="hidden" name="cmd" value="_xclick" />'; echo '<input type="hidden" name="item_name" value="donation" />'; echo '<input type="hidden" name="custom" value="'.$charname.'">'; //your paypal email echo '<input type="hidden" name="business" value="'.$mypaypalemail.'" />';

example ipn:

$gethelmet = $p->ipn_data['option_select0']; or never work ?
if so, best solution can try accomplish ?
thanks in advance.
the docs can use parameter custom pass custom data (max length=255) https://developer.paypal.com/docs/classic/ipn/integration-guide/ipnandpdtvariables/
depending on situation pass custom notify_url , pass data wanted in ipn url.
p.s. holy echo's batman.
