Try this code:


<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="dev1@ferozitech.com">
<input type="hidden" name="item_name" value="test" class="slug">
<input type="hidden" name="item_number" value="2" class="proposalId">
<input type="hidden" name="custom" value="" class="userId">
<input type="hidden" name="amount" value="40" class="amount">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="rm" value="2" />
<input type="hidden" name="lc" value=""/>
<input type="hidden" name="no_note" value="1"/>
<input type="hidden" name="return" value="<?php echo base_url('payment/payment_complete/') ?>">
<input type="hidden" name="cancel_return" value="<?php echo base_url('payment/payment_cancel') ?>">
<input type="hidden" name="notify_url" value="<?php echo base_url('payment/payment_complete/') ?>" />
<input type="image" name="submit" src="<?php echo base_url('images/checkoutpaypal.png'); ?>" alt="PayPal - The safer, easier way to pay online"> 
</form>

Return url notify_url payment_complete function

print_r($_REQUEST);die;
