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.

Add Extra File Field(s) To The Form

Apr 23, 2009

I'm stuck with this one since my knowledge of javascript is very low, PHP I'm ok with but this is a new language to me. Anyway, I have a form (a table-less one) which I would like to have the ability to add extra file fields if needed. One is already placed but I would like the user to have the option to add more photos. Here's my html:

Passing Extra Data Along With Form Submission

Jul 15, 2011

Mootools 1.3 user here. I am just wondering if I can pass extra data along with form values when I use the \$('myform').submit(); method.

I am wondering if there's anyway to attach data the same way you do with a Request object (ie: Request.send(data) or do I have to create hidden inputs in my form to pass the values?

The reason is some parts of my form are dynamic. The user can add as many entries as he wants. Those entries are stored in an object that's a module's property (Modyle.property = {obj, obj, obj}).

I am wondering if I'll have to iterate through the entries and create hidden inputs for each before submitting the form or can I just create a string that I can pass with my Form.submit() statement?

Jan 2, 2010

I am trying to find a way to add an extra piece of hidden text onto the end of the text a user enters into the form field so that when the form is sent the extra text will automatically be added to the end before sending.

Calculating 2+ Form Field Inputs On The Fly

Mar 6, 2007

I'm working on a financial form that is filled out and then a pdf is outputted (via php).

I'm an xhtml/css and php guy but new to javascript - I'm sure there's got to be a way to do the following with js...

I've got a section for "project costs" with 4 fields (numeric is expected). I'd like to add a 5th field "Total Project Cost" that adds all the inputs of the first 4 fields on the fly as they are typed (or at least, after focus changes).

Also I'd like to have a field which defaults to "10" and a drop down with 3 items that will either add 0, 5 or 10 to the field which defaults to 10.

Code To Auto Update Price When Form Field Value Are Changed?

Write A Script That Adds An Extra Field To A Form When Needed

Feb 11, 2010

I have been trying to write a script that allows a user to click on a button like a plus sign to add an additional field for a phone number when they have more than one phone number to enter. I have created a script that sort of does this. It doubles up what is already there, so, the first time, everything is fine, but after that I get a lot more fields than I want. I am a php programmer and not familiar enough with javascript to get to what I want. My script is included below. What I am doing here is retrieving the html content and then adding it to what is already there. In php I would use an if conditional test to see if the data has been retrieved.

The first time it would retrieve the data into a variable. After that it would not retrieve it. I think I am getting into some scope and sequence issues here. Javascript is a bit different than php in these regards. Also there is a commented line in the code that asks another question about the use of variables that I don't understand. I also tried using appendChild() here to no avail. I couldn't get that to work at all.

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"><!--
document.forms['hours'].elements['onktotal[]'].value = (document.forms['hours'].elements['onkqty[]'].value.replace(",", ".") -0) * (document.forms['hours'].elements['onkprice[]'].value.replace(",", ".") -0);

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>

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..

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:
>drop down list (name courseName, value of selections 1,2,3,4)
> radio button (name returnStudent, value of selections 1,2)
