</form>
The payment transaction is completed successfully and the redirect is done perfectly to my application. But the problem is i didn't get any response in that page. I tried var_dump($_POST). It retruns null. Don't know why i didn't get any response. Any help is appreciated.

Check the following link and update your paypal account.The response is in $_GET

How to make sure the paypal notify_url being called from paypal server?

I was working with paypal recurring payment subscription form and using sandbox account for testing
here is my form:
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick-subscriptions">
<input type="hidden" name="business" value="testacc#email.com">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="item_name" value="Standard Pack">
<input type="hidden" id="item_number" name="item_number" value="1233434-23213">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="user_id" value="13692">
<input type="hidden" id="package_id" name="package_id" value="<?php echo $package_type; ?>">
<input type="hidden" name="a1" value="0">
<input type="hidden" name="p1" value="1">
<input type="hidden" id="t1" name="t1" value="M">
<input type="hidden" id="a3" name="a3" value="10">
<input type="hidden" name="p3" value="1">
<input type="hidden" name="t3" value="M">
<input type="hidden" name="src" value="1">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="no_shipping" value="1">
<input name="return" type="hidden" value="<?php echo base_url();?>package/new_payment_success" />
<input name="notify_url" type="hidden" value="<?php echo base_url();?>package/new_payment_notify" />
<input name="cancel_return" type="hidden" value="<?php echo base_url();?>package/new_payment_cancel" />
<div class="paypal-btn">
<input type="image" src="pay-with-paypal.png" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!" style='width: 125px'>
</div>
<img alt="" border="0" src="https://www.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>
and it's working totally fine and sends a success information to notify_url url
now for security purpose im checking HTTP_USER_AGENT from $_SERVER variable but this can be modified too.
so how can i make sure that transection is done successfully before i update my database?
I think that you can verify the whole POST content by appending cmd=_notify-validate and sending it to PayPal. They will answer you with a Verified or Not verified response.

Want to connect my shopping cart total price to a paypal checkout

I have a displaycart.php page where it displays all items I have in a shopping cart, each item has an ItemUnitPrice field where it shows the unit price of the item.
If I have say 6 items in the cart then I want to add up the total ItemUnitPrice fields and set that amount to be paid with PayPal.
I have checked out PayPals button features which they allow and you can only set a given price for the user to pay for when you create the button.
Is there a way I can link the PayPal button to my database so it shows the total of all the ItemUnitPrice fields.
The variable which holds the total ItemUnitPrice:
<?php
$Total = $Quantity * $ItemUnitPrice;
?>
The PayPal 'Pay Now' Button:
<html>
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="KAMQ5PVWVDYYN">
<input type="image" src="https://www.paypalobjects.com/en_GB/i/btn/btn_paynow_LG.gif" border="0" name="submit" alt="PayPal – The safer, easier way to pay online.">
<img alt="" border="0" src="https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>
</html>
Edit:
Yeah I've done something stupidly wrong!
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_BLANK">
<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="business" value="info#asianweddingservices.org" />
<input type="hidden" name="item_name" value="<? $ItemDesc ?>" />
<input type="hidden" name="item_number" value="<?$ItemCode ?>" />
<input type="hidden" name="amount" value="<?$Total ?>" />
<input type="hidden" name="currency_code" value="GBP" />
<input type="hidden" name="lc" value="GB" />
<input type="hidden" name="bn" value="PP-BuyNowBF" />
<input src="paypal/purchase.png" name="Submit" type="image" value="purchase" alt="Purchase" />
</form>
Yes. Change the set value to your total.
Show your code and I can edit the answer to fix it for you.
Add this:
<input type="hidden" name="amount" value="<? echo $Total; ?>" />
If that doesn't work:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_BLANK">
<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="business" value="PAYPAL EMAIL" />
<input type="hidden" name="item_name" value="ITEM NAME" />
<input type="hidden" name="custom" value="CUSTOM VALUE" />
<input type="hidden" name="item_number" value="ITEM NUMBER" />
<input type="hidden" name="amount" value="TOTAL" />
<input type="hidden" name="currency_code" value="GBP" />
<input type="hidden" name="lc" value="GB" />
<input type="hidden" name="bn" value="PP-BuyNowBF" />
<input src="paypal/purchase.png" name="Submit" type="image" value="pruchase" alt="Purchase" />
</form>
Replacing the values to yours of-course.
