Auto Calculate Form Fields Value Using JQuery Calculation Plugin

Jan 6, 2011

I am building a form that will automatically calculate the values entered by a user ideally using jQuery/javascript, i am not sure how to do this but have a general idea of the logic required (i am no expert so feel free to correct me) - I have created a dummy image to help explain what I am trying to do.


I have a single form, which has many input fields automatically calculate the total amount for each table provided it has been selected. Using jQuery - I would expect the logic to be something like -

i) Find the input field element ii) Find all the text fields within the table that have a value iii) Add these together and display in the 'total' form field

While i'm ok on the PHP, javascript is something I still get confused with at times -

Use JQuery To Add Form Fields And Sessions To Remember The Fields Were Added

I am creating a multi-paged form and now i am consulting the Stack guru's for some assistance; On this page the user can add more input fields [type=text] onto the page. So basically there is a singular input for "CHILD NAME" then a Add button to allow the user to add more children if they have more than one.

My form allows you to go backwards and forwards, the form remembers what was input, how would i get jQuery and php to remember that the form fields were added so they are not hidden when the user re-vists the page?

Validation With Jquery Form Plugin?

This is the first time I have attempted to make a form using jquery and php. I used the folks over at Mid Mo Design as an example but even with that tutorial am still having trouble getting it to do what I want. This is the code I have been using. As well as jquery 1.4.1 and jQuery Form Plugin 2.43.


#scrollContact {
border-top: double 1px #0D0D0D;
padding: 100px 50px 50px 50px;[code]...

Auto Populating Form Fields

I know this isn't a PHP thing. But, I've been unsuccessfully looking for how to populate form fields with data found in other fields.

For example, I would like to populate shipping information with the billing information - if they are the same. This would save the time from entering the same address twice.

Does anyone know of a javascript site that is decent at these options?

Auto Create Form Fields

is there a way in php to look up a mysql table and use the column headings as form field variables … meaning with this php program the entire table columns are displayed as form fields in the browser ?

No need then to build the form by hand … in this consequence there could be a input type column and a width column which could be used to also automatically create the right types of fields for that particular mysql table …

Auto Fill - Use Eleven Form Fields On Page

I am trying to use eleven form fields on a php page where one of the fields will be used to enter a user name (or id number) and have the remaining fields fill in with the data I have for that user. I have over twenty records in m database and I need (I think) a menu/list as well that does the same thing so I can see all files in the list and click on a name (or id). how to do this for a single field entry (user name) as I can remember (or view) the files using XAMPP but there will come a point where I am unable to do this so I would also need help with the menu/list option.

Ajax In Form Then Jquery To Display Filled Form Fields

I have a form that requires a physical address. Once the user enters the full address, I have a button that says "Verify address". I want to be able to click that button, trigger an ajax call that will call a file in the server which will get the longitude and latitude of that address, then return to the form with those coordinates, and display a div with them. Dont worry about figuring out the coordinates. Im just trying to figure out the whole ajax call and jquery display upon response from the server So, I did this;

$(document).ready(function() {
//if verify button is clicked
$('#verify').click(function () {
var address = $('input[name=address]');
var city = $('input[name=city]');
var state = $('input[name=state]');
var zip = $('input[name=zip]');
var country = $('select[name=country]');

process.php returns the longitude and latitude back in a variable as: "longitude,latitude". How do I access that data back in the front end so I can populate the form fields with it?

Paypal IPN Setup - Ship To Zipcode And Auto Calculation?

I have successfully setup paypal IPN on my site and its working fine. From my paypal account I have set options to ass shipping and tax calculations(only if it's Iowa). But the only issue is, on the paypal checkout page it's asking me to enter the "Ship to Zipcode" manually.if I enter and update only then the net payable is getting updated with the shipping and tax charges.

Is there any variable via which I could send the ship to zip code which will work directly on the cart and make it auto calculate the charges and show it? I have tried both "zip" and "address_zip" variables. None of them worked. By the way I have multiple items on my cart so I am using the "cart" transaction type.

Jquery Repopulate Table Form Fields?

I have a simple html table that starts off with two rows. Each row contains 2 form fields. User's can add additional rows to the table as follows:

$('a#addRow').click(function() {
$('#jTable tr:last').after('<tr>'+
'<td><input type="text" name="foo[]" value="" id="foo[]" /></td>'+
'<td><input type="text" name="bar[]" value="" id="bar[]" /></td></tr>');
return false;

This works fine.

However, if there is an error detected after the form is posted, then I need to recreate the table with the correct number of rows. At the moment, after posting, the table defaults back to the two starting rows only.

JQuery Autocomplete Not Working For Dynamic Form Fields

I am using jquery Autocomplete on a form field. The issue is, then dynamically I add another row to the form, it doesn't. Yes, I keep toggle the id of the new field to a new one.


I think the problem is that jQuery is not recognizing the dynamically added elements, it only reads the elements present on load. Is there any way that we can poke the jquery handler to read these new added elements? I heard of the bind and live functions, albeit I cannot find a way to implement those.

Jquery - Read Text File Into Div Then Add Positioned Form Fields?

I have multiple text files, which are simple reports, that must be reviewed and validated by users. I would like to pull the report into an html div element then add form fields at absolutely positioned locations. For example, the report may have monthly sales by sales rep:

Jan Feb Mar
13 9 11

I want the user to see that, and an input type="text" element after the row of sales numbers. The user would have to enter their initials to confirm the numbers. At that point, I would actually modify the text file to show their initials (as well as set some flags in the database). The site is built using PHP and JQuery, with some cgi perl scripts as well. So solutions involving any of those would be great.

Jquery - Large Enable Web Form - Around 75 Field - Best To Send Email With All Fields?

Have created simple Ajax enabled contact forms before that have around 12 fields - worked fine.Now working on a PHP enabled web page for job applications that has around 100 fields.The ajax technique I was using was to send request via querystrings(&val1=test;&val2=test2 and etc ...)

That is not going to scale very well with larger form with 100+ fields.
Maybe use jQuery Form plug-in instead?

Comparing Form Fields With Data Base Fields And Highlighting The Form Fields?

the following two scenarios (PHP+MYSQL)

Scenario1: I need to compare the HTML Form field values with the Database field values and highlight the form fields in some color whose values are different from database values before submitting the form (to alert the user).

Scenario2: On loading the form, i need to compare the values present in 2 different database tables (tables are having different column names but the information is same). the fields which are not same needs to be highlighted in the html form to indicate the users that the master data is varying from secondary data.

Netbeans, Auto-formatting IDE Inserts Braces, Quotes, In Plugin?

Note that this is not about auto-completion or the excellent code formatter, Alt+Shift+F.Right, so I've tried to let the auto-close braces, brackets and quotes 'grow on me.I've coded PHP in NetBeans for a few months now.Especially, fixing up an echo HTML-line that is lacking one single or double quote is a terrible experience, same thing for when I cut out a few lines ending with a brace to put it below a code line that should be inside the braces.
