Dynamic Pricing Based On Selection

Hi, I would like a price to appear on the checkout page based on a selection from a previous page. I therefore DO NOT want to create a product and assign a fixed price to it.
Let me explain a bit more-:
I have built a prototype site which allows persons to pay insurance. Insurance amounts will vary from person to person and are subject to change each year. Currently I have a page in joomla! which has a dropdown menu where persons can select the portion of insurance they want to pay. I want that when a user selects their insurance portion and selects 'OK', the selected amount will appear on the checkout page.

Does hikashop offer this functionality or is there a way to modify the code so as to facilitate this action. If there is a way, please tell me how.

Thank you

Hi again,

I tried to follow your instructions but I was not successful. I am not an expert so that may be part of the problem. To further clarify what I wish to happen:-

Currently I am able to pass the amount that a user selects in a session variable. I just want that session variable to appear under the 'Unit Price' field on the checkout page.

Is there a simple way to do this?

Hi again,

You have been helpful so far but now I need some additional functionality.


I tried your suggestion of replacing $product->amount with $_SESSION which pulls from a drop-down menu as shown in code below:-

<?php
jimport('joomla.plugin.plugin');
class plgSystemCustom_price extends JPlugin{
}

function hikashop_product_price_for_quantity_in_cart(&$product){
$currencyClass = hikashop_get('class.currency');
$quantity = @$product->cart_product_quantity;
if(empty($product->prices)){
$price= null;
$price->price_currency_id = hikashop_getCurrency();
$price->price_min_quantity = 1;
$product->prices = array($price);
}
if(!empty($_SESSION)){
foreach($product->prices as $k => $price){
$product->prices[$k]->price_value = $_SESSION;
$product->prices[$k]->price_value_with_tax = $_SESSION;
}
}
$currencyClass->quantityPrices($product->prices,$quantity,$product->cart_product_total_quantity);
}

function hikashop_product_price_for_quantity_in_order(&$product){
$quantity = $product->order_product_quantity;
if(!empty($product->ordered_length)){
$product->order_product_price = $_SESSION;
$product->order_product_tax = 0;
}
$product->order_product_total_price_no_vat = $product->order_product_price*$quantity;
$product->order_product_total_price = ($product->order_product_price+$product->order_product_tax)*$quantity;
}


I would now like to update this code so that if the session variable is not selected from the drop-down list, the $product->amount which I created on the HikaShop-->Products page will be used instead.

Thank You again

Hi again,

I tried your suggestion but my page loads blank.

Below is the code I tried:-
(I am a novice somewhat so maybe I have something incorrect)

Please advise. Thank You again.

<?php
jimport('joomla.plugin.plugin');
class plgSystemCustom_price extends JPlugin{
}

function hikashop_product_price_for_quantity_in_cart(&$product){
$currencyClass = hikashop_get('class.currency');
$quantity = @$product->cart_product_quantity;
if(empty($product->prices)){
$price= null;
$price->price_currency_id = hikashop_getCurrency();
$price->price_min_quantity = 1;
$product->prices = array($price);
}
/* if(!empty($_SESSION)){
foreach($product->prices as $k => $price){
$product->prices[$k]->price_value = $_SESSION;
$product->prices[$k]->price_value_with_tax = $_SESSION;
*/
if(isset($_SESSION) ? $_SESSION : $product->amount){
foreach($product->prices as $k => $price){
$product->prices[$k]->price_value = isset($_SESSION) ? $_SESSION : $product->amount;
$product->prices[$k]->price_value_with_tax = isset($_SESSION) ? $_SESSION : $product->amount;


}
}
$currencyClass->quantityPrices($product->prices,$quantity,$product->cart_product_total_quantity);
}

function hikashop_product_price_for_quantity_in_order(&$product){
$quantity = $product->order_product_quantity;
if(!empty($product->ordered_length)){
$product->order_product_price = isset($_SESSION) ? $_SESSION : $product->amount;
$product->order_product_tax = 0;
}
$product->order_product_total_price_no_vat = $product->order_product_price*$quantity;
$product->order_product_total_price = ($product->order_product_price+$product->order_product_tax)*$quantity;
}

Hi again,

I will not be able to check for at least another 7 hours.
Could you tell me in the meantime if my modified code looks correct with the "(isset($_SESSION) ? $_SESSION : $product->amount)" line which you suggested?

Also how do I set error reporting to maximum?

Please direct me step by step.

Thank You again
