Update 'total' Field With Multiple Price Fields?

Nov 11, 2010

i am currently developing a cart for a website at my company.What i am attempting to do is update the grand total field dynamically as the product total (determined by quantity & price) are being populated.Each product in the cart is being generated by a foreach (php) reading from a mysql database.As the total values are not being prepopulated im not exactly sure what the logic would be to get the desired values.

I will also mention im relatively new to the whole web development area, i started begining of this year and feel i could still learn alot about the 'logic' of a computer.If anything is unclear about what i stated above feel free to request additional information.

Auto Update Price Based On Form Fields?

Aug 7, 2010

I am more of a front end guy with experience in xhtml/css and want to get my hands dirty with some back-end programming (Javascript/jQuery/AJAX/PHP) and was wondering about a specific task involving (mainly) what I would believe is AJAX.

I was wondering if there is a way to have a page with a starting price of $299 (lets say a basic vacuum) then below that are 20 or so customizable add-ons to choose from through simple checkboxes. That (to me) should be easy enough, but I would love to have the grand total at the bottom of the page be updated in real time as the user checks or unchecks certain add-ons (kind like how apple.com does it).

What is a good starting point for this, and would it be possible to send out the order as an email with the total price sent to the business owner.

Multiple Selects To Update The Price?

Apr 19, 2010

I am building a system for creating a booklet.I want the user to be able to select the quantity of booklets they require. (eg 50, 75, 100, 125)Then also select the number of pages each booklet will require. (eg. 4, 8, 12)

both will be select drop down boxes.I would like the price to be calculated based on the selections and displayed on the page.It will be total price not price per booklet.This is how i have built up the prices in php.

if($b_maxpages == '4' && $b_quantity == '50') { $amount = "95.00"; }
elseif($b_maxpages == '4' && $b_quantity == '75') { $amount = "103.00"; }
elseif($b_maxpages == '4' && $b_quantity == '100') { $amount = "115.00"; }

[code]....

I will also need the selected data to be posted once the form is submitted.

Calculate Total Price In Added Tablerow

Sep 12, 2010


i have a table inside a form, with input fields ( price, qty, desc, total ( to be updated ), this works as it should with the following javascript:

<script type="text/javascript"><!--
function updatesum() {
document.forms['hours'].elements['onktotal[]'].value = (document.forms['hours'].elements['onkqty[]'].value.replace(",", ".") -0) * (document.forms['hours'].elements['onkprice[]'].value.replace(",", ".") -0);
}
//-->
</script>

now the problem occurs when i put more rows there then the javascript function does not work anymore, my ultimate goal is to create a function to add tablerows with javascript, but i'm trying to create the update function with a static situation first.

Total Price To Be In DIV And Not Input Type Text

Dec 5, 2010

Firstly, I got this script which gets values and automatically calculates it and shows result.
Script:
<script type="text/javascript">
function calculate(f){
var prod=Number(f['users'].value);
var quan=Number(f['months'].value);
var tot=prod*quan;
f['total'].value=tot==0?'':tot.toFixed(2);
}
</script>
<ul><li class="bold">Users</li>
<li>
<select name="users" onchange="calculate(this.form)" id="users">
<option value='1'>1</option>
<option value='2'>2</option>
</select>
</li></ul>
<ul><li class="bold">Period</li><li>
<select name="months" onchange="calculate(this.form)" id="months">
<option value=''>Select Months</option>
<option value='1'>1 Month</option>
<option value='2'>2 Months</option>
</select></li></ul>
Total: <input type="text" name="total" readonly="readonly">

What I'm trying to make is, the total, to be in a div and not input type text
Something like <div id="total"></div>
I don't like because it shows in form, I want it directly. One more thing, is possible to make the default price 0.00 ? and when selecting automatically changes to price..

Auto Update Price When A User Changes Options To An Item?

Dec 22, 2011

What i am trying to do is allow a user to get a quote on how much an item would be if they wanted to sell it. all the data is being generated dynamically on the item and passed to this JavaScript correctly. The issue is when a user changes his mind and switches his options a few times the price goes out of wack and some times will actually be more then the original price. For example. If the item was in mint condition it would be 100 dollars. If it is " good condition" then it would loose lets say 20 percent, so it would be worth 80 dollars. Now each item has 3 sections of questions, what is the condition of the item, any "modifiers" like water damage or functional issues, and then third section is if its missing any parts or cables. All of this is being asked on 1 page, and when a user changes any of the options it should update the price on that page with out the user needing to press update. So condition goes, 100%, 70%, 40%, 20%. Modifiers are 50 percent of current price of item, so if it was "perfect (yes I know an item cant be perfect and have water damage but this is just an example) thus being 100 dollars, and has water damage, that would make it now worth 50 dollars, and has functional issues, now worth 25 dollars. If it was missing cables, it would loose lets say 5 dollars so now its worth 20 dollars. Thats an example on how i calculate the value of the items. So once again, the actual amount is being passed correctly to this script, but when you make to many changes its not happy.

Writing A Price Based On Selection Of Input Fields?

Aug 29, 2011

I have a registration form that I am working on in which I need to assign a price to each option in a selection box then write that price in the document.Then I have a radio button that will add (different amounts based on selection) to that price before it is written. Then I have another radio button that just needs to write a price based on its selection. Both of these values will be written and then totaled. (See below for a less confusing explanation)

On HTML form:
