How to get HTML form data into PHP function Arguments?

[aveeva]

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:

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.

[aveeva]

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.

@gits I am facing error while select shipping cost, if i select anyone from dropdown all the values saves into db, how to modify my code.
Output : https://snag.gy/BIJZb7.jpg

Any help thanks.

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.
