The Business Logic is: If product is already purchased, upgrade the product
I have a customer input form to get information, along with some fields which should be auto populated based on what the customer chooses.
Screen Shot:
https://i.stack.imgur.com/Fkyim.png
Note: Price and Shipping Weight are done with Ajax,
When we come to the shipping cost I am getting it from Magento, using a PHP function.
form :
https://paste.ofcode.org/335FVUhpBGbazQtrcPLVQUs
PHP :
sp_cost.php
https://paste.ofcode.org/hvG2sP9TW9CEPgMMuKXNuw
From the above code I am given the predefined value,
$results = getShippingEstimate('14419','1',"IN","642001");
How can i get country and zipcode from the user entry and return the shipping cost?

in the code here: https://paste.ofcode.org/335FVUhpBGbazQtrcPLVQUs
you can easyly see that at the bottom are 3 script-elements that basically do assign an event-handler (onchange) to the element with the id="new" - and all 3 handlers invoke a request each with passing the exact same data to different endpoints: -
var old_val = $("#old option:selected").val();
-
var new_val = $("#new option:selected").val();
-
-
// ...
-
-
data: { old: old_val, new: new_val},
-
this means that you simply need to retrieve the data from the fields correctly in your javascript sections and pass it in the data-object of the ajax call to the endpoint(s) that should receive it. For optimization of all that it would even be preferable to just send 1 request and not fire 3 in parallel.

@gits : Okay, with my code how can i use input form values in PHP function arguments,
as said,
sp_cost.php https://paste.ofcode.org/hvG2sP9TW9CEPgMMuKXNuw
From the above code I am given the predefined value, - $results = getShippingEstimate('14419','1',"IN","642001");
-
How can i pass my zip code & country from form and pass by using ajax.
i know the following is wrong, how can i write the right code, - <script>
-
$(document).ready(function(){
-
$('#new').on('change',function(){
-
-
var old_val = $("#old option:selected").val();
-
var new_val = $("#new option:selected").val();
-
-
$.ajax({
-
type: "POST",
-
// url: "ajax_ship_cost_data.php",
-
url: "sp_cost.php",
-
dataType: "text",
-
data: { old: old_val, new: new_val},
-
success: function(data)
-
{
-
// Check the output of ajax call on firebug console
-
//console.log(data);
-
$('#findata').html(data);
-
$('#shipping_cost').val(data);
-
-
}
-
});

-
</script>

as i said - you need to retrieve the correct values from the form elements and pass it to the data object in the jQuery ajax call. I suggest to read the jQuery API docs if you don't know how to do it - i probably won't write the code for you - basically its easy changes and considered as the minimum knowledge when working with jQuery. you can start from here: http://api.jquery.com/val/
for example and then go on from there.

Using this -> http://api.jquery.com/val/ i did my couple of fields as you see [Price & weight]. Here shipping cost field is not predefined value, actually it gets from Magento [PHP CMS]. I need some help regarding how to pass my value which is getting from Magento and insert into shipping cost field, for me, it's quite tough, workout :
My PHP function : - <?php
-
ob_start();
-
// require_once(__DIR__ . '/app/Mage.php');
-
require_once('./../app/Mage.php');
-
umask(0);
-
ini_set('display_errors',true);
-
ini_set('memory_limit', '1024M');
-
Mage::app()->loadArea('frontend');
-
-
function getShippingEstimate($productId,$productQty,$countryId,$postcode ) {
-
-
// $quote = Mage::getModel('sales/quote')->setStoreId(Mage::app()->getStore('default')->getId());
-
$quote = Mage::getModel('sales/quote')->setStoreId(Mage::app()->getStore('english')->getId());
-
$_product = Mage::getModel('catalog/product')->load($productId);
-
-
$_product->getStockItem()->setUseConfigManageStock(false);
-
$_product->getStockItem()->setManageStock(false);
-
-
$quote->addProduct($_product, $productQty);
-
$quote->getShippingAddress()->setCountryId($countryId)->setPostcode($postcode);
-
$quote->getShippingAddress()->collectTotals();
-
$quote->getShippingAddress()->setCollectShippingRates(true);
-
$quote->getShippingAddress()->collectShippingRates();
-
-
$_rates = $quote->getShippingAddress()->getShippingRatesCollection();
-
-
$shippingRates = array();
-
foreach ($_rates as $_rate):
-
if($_rate->getPrice() > 0) {
-
$shippingRates[] = array("Title" => $_rate->getMethodTitle(), "Price" => $_rate->getPrice());
-
}
-
endforeach;
-
-
return $shippingRates;
-
-
}
-
-
// echo "<pre>";
-
// product id, quantity, country, postcode
-
// print_r(getShippingEstimate('14419','1',"IN","642001"));
-
-
// echo "</pre>";
-
-
//$results = getShippingEstimate('14419','1',"IN","642001");
-
-
// $results = getShippingEstimate('14419','1',"US","99501");
-
-
-
-
<!-- if(isset($_POST['zip_postal_code']) && isset($_POST['country']))
-
{
-
$zip_postal_code = $_POST['zip_postal_code'];
-
$country = $_POST['country'];
-
} -->
-
-
-
$results = getShippingEstimate('14419','1',"IN","642001");
-
-
//$results = getShippingEstimate('14419','1',"$country","$zip_postal_code");
-
-
-
$count = -1;
-
echo "<select>";
-
foreach ($results as $result):
-
$count++;
-
?>
-
<option value="<?php echo $count; ?>"> <?php echo $result["Title"]." - Rs ".$result["Price"]?>
-
</option>
-
-
<?php
-
endforeach;
-
echo "</select>";
-
?>
FYI -> In PHP function :
shipping cost calculated using :
$results = getShippingEstimate('14419','1',"IN","642001");
and passing the shipping cost value using,
<option value="<?php echo $count; ?>"> <?php echo $result["Title"]." - Rs ".$result["Price"]?>
</option>
Note: By using $results = getShippingEstimate('14419','1',"IN","642001"); its returned the value, i need if customer enter the zip_code and country, once the customer entered those values using ajax passing value to -> $results = getShippingEstimate('14419','1',"IN","642001"); and returned to the shipping cost.
I hope I explained well. Can I get some help?

Solved :
Actually error in Ajax & error in passing fields, - <script>
-
$(document).ready(function(){
-
$('#new').on('change',function(){
-
-
var zip = $("#zip_postal_code").val();
-
var country = $("#country").val();
-
-
$.ajax({
-
type: "POST",
-
// url: "ajax_ship_cost_data.php",
-
url: "sp_cost.php",
-
dataType: "text",
-
data: {zip_postal_code : zip, country: country},
-
success: function(data)
-
{
-
// Check the output of ajax call on firebug console
-
//console.log(data);
-
$('#findata').html(data);
-
$('#shipping_cost').val(data);
-
-
}
-
});
-
-
});
-
});
-
</script>

grats :) the only thing to note is that the requests are only send when the value of the select-element with id="new" is changed. so if a user only changes some other field like zip-code or something else - the request is not fired. If that's how it should work then all is good - else you would need to attach the the correct eventhandlers to the fields that are relevant for new calculations.

this screenshot doesn't tell much. your program in fact acts as you programmed it. in case the code didn't change much - you fire at least 3 requests in parallel always when you change the value of the select-element with id="new". So you need to check all entrypoints that you call and even if its necessary/correct to call them all at the same time - and see what values they get received and what they then do - i cant help much with that without seeing more of the actual code.
