AJAX :: Auto Update Depending On Database Value?

May 13, 2010

I have a been developing an Online auction website using PHP and Mysql for the last few weeks. I have implemented everything including the 'bidding', 'buy it now' options of the auction etc.

I don't know much about AJAX to be honest, but I think it is the technology I need for this... My requirement is to devise a way of updating (in real-time) the current price of a particular auction product as more and more users bid on the item. Once a user bids on the item, the bid table of the database is updated with the highest bidders price. So once this value changes in the database, would it be possible to update the price on the webpage? Obviously, it is important for this update to be as accurate as possible to maintain the integrity of the auction.

JQuery :: Ajax POST Designed To Update Database Table Updates All Records At Once

Jul 12, 2011

This jquery code pulls in an XML file, then passes the contents down to the nested POST call to add all of the records from the XML into a database table (which is handled by the saveSenatorRecord.asp file). This all works fine.. except that when the POST is called for "EACH" of the member nodes I expected the success: function to be called once after each of the records are added to the table. But what appears to be happening is that when function is called in the EACH property... it adds all of the records to the database table at one time, THEN it calls the success function once for each individual record.. but AFTER they have all been added.

Form Update Depending On Which Values Were Entered

Dec 7, 2009

I have a form that works out some basic math questions e.g. area etc. I run a function when a form field is updated to do the calculations, however I'd like to run a different calculation depending on which form element was updated. Is there a way to say something like:

if (area1 was updated) {
work out this calculation
}
if(area2 was updated) {
work out this calculation
}
and so on?

I'm trying to update a shopcart depending on radio button choice, the problem is when I'm submitting and want to go to the next page.

Imagine this, I'm on a page with 2 radio buttons, either u can pick A or B, depending on my choice the shopcart gets updated, and its placed in the bottom of the page, to that point everything works fine.But when I post from my form and get redirected to the next page it seems like my jquery function runs again and choose the first radio button even if i have the second selected when posting.$cart is the class object and i add the items with just a name and some price parameters.

Update Database On Browser Close

Nov 12, 2010

I am working on a chat program. When a user logs in, a value in the database is set to 1 (online), and when he/she logs out it is set to 0 (offline). The problem is, when the user exits the browser, naturally the value is still set to 1.

I was wondering if it is possible using AJAX or otherwise to update the database on the event of browser close? I have tried onbodyunload in the body tags pointing to a file with a JavaScript function containing the PHP code (query to update the field) but cant get it to work.

Help With Form Auto Update

Jan 4, 2006

For instance, Box A has a blank entry and I enter in 5. Box B I enter in 6
so in Box C it should automatically give me 11 (if the code I put in is to
add box A and B). Then in Box D I put in 3 (say to subtract from A and B
combined) so then Box C adjusts to give me 8.

Don't worry about the math as that's all taken care of it, I just need to be
able to know how to update on the fly like this.

Auto-update DIV Content (images)?

May 4, 2011

This is my first venture in this forum and also my first attempt at some programming for a fair few years and I have run into a problem i cannot for the life of me see the answer to. I am fairly sure I am just missing something stupidly obvious, but like I said its been a few years since I did any programming so I'm a bit behind with my knowledge!

What I am trying to do is using a combination of HTML & Javascript (well actually JQuery), is to automatically update a cell in a table without the user doing anything. The changes to the content are based on changes to a database by other users. I have written the following code which auto updates text in the DIV, the question is how do I ammend this text to automatically switch between pictures?

JQuery :: Update HTML With Id Attribute From Database After $ Request?

Oct 8, 2010

I was wondering if someone could help me out with the following.I'm developing a webshop CMS in which you can create categories. By using jquery's ajax method I'm making a POST request to a PHP script which then handles all the data supplied to it. This works good and all except for the fact that after the query is being executed my HTML doesn't get updated, at least not as well as I want it to.I understand that the common way of working here is to update HTML in the success callback of the ajax method. But the thing is that every category is being displayed as a list item with an id attribute, this id corresponds to the id the category has in the database.If$.ajax tells me that everything went down smoothly and my query has been executed then there's still no way for me to know which id this new category has been given so that I can update the HTML accordingly.

What would be a "smart" way to tackle this? The first thing that comes to my mind is simply calling another script which figures out the last inserted id on the db but that would mean doing an ajax request in the callback of another ajax request? That doesn't sound right to me..

Altering Mootools Rating System To Update Database?

Nov 9, 2009

im trying to add a star rating system to a website. id like to do something elegant graphically instead of just using a drop down... the javascript framework im using is mootools and i found a great rating system here, but have no idea how to adjust it so that it updates the database with the new rating vote from the user and it calculates the new average rating.

the way i have the database set up for this is with the following fields: id (the rating's unique id) listingid (the listing that the rating corresponds to) userid (the user that entered the rating) rating (the rating itself)

i use php to communicate with a mysql database. the file im going to write will check to see if there is already a rating entered in from the logged in user. if there is, it will update it. if not, it will insert it, then it will calculate the average of all votes for that listing (rounded up) and return the new rating to the page and set the stars to reflect that rating... ive tweaked the code a bit to represent a 5 star system instead of a 10 star system and also so it can be used multiple times on a page.

heres what ive been playing with:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

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.

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.
