Populate A Member List In A Chatroom?
Nov 28, 2011
I am facing the above problem for a chatroom app that I am making. People will enter and exit the room any time they want, so i need a member list that updates itself to reflect this on the screen of all users that are in the chatroom. What i have thought of, is to have JS call a PHP function on specific intervals, and that PHP function will retrieve user data from a database and pass it to JS to display on the list. Is this method advisable? Are there any more suitable ways of doing this? I am thinking of applying the same theory for displaying and retrieving chat messages, but i get the feeling that something's missing for this, or maybe this method is not right for displaying messages.

I am trying to get the price updated based on users dropdown selection for Member and Non-Member and also multiply it by how many they want.Should I use javascript on the page or split the page into two where 1st one would collect basic info and if they are member or non members and second would collect quantity?

I have 3 ASP list boxes. I would like to populate the second list box based on the selection in the first list box and based on the selection in the second list box, populate the third. I would like to do this using AJAX. How can I do it? Can someone please give me the code snippet as I am a complete noob when it comes to AJAX and I kinda am running outta time to finish implementing it. Additionally, should I use ASP boxes or HTML <select> tag?

I have several lists each of several hundred selectable items. I send
all lists to the client along with the javascript. When the user types
the first letter of the item in a text box, I know which list to
present- it is likely the user will wish to view several of the lists
concurrently (I am not concerned at the extra load time of a few
thousand items sent via javascript). However, I am trying to do
everything client side- (even if I use ajax to call the list from the
server, there is delay at the client side as the listbox is populated
with appropriate items) - can anyone think of a manner of presenting a
long list dynamically, based on the first letter typed, client side
and with the absolute minimum of delay? (These items then need to be
selectable)

I know that this is very basic to most of you JS Guru's out there, but I am stumped. I have found dozens of tuts on this, but can't seem to find a VERY simple basic version of it. This is what I want, actually my client wants. I want to have a select list that gives the options of countries. Then upon selection this changes the drop down list of the states/provinces listed. So when I click on Europe it shows the different sections of Europe, and US it shows the states (I'm sorry I don't know what Europe calls their equivalent of a state), etc.

I am using Javascript & PHP to populate a select list. The Ajax is working perfectly as I have tested it. However, as you can see from the below code, I have a button which adds more rows (which includes 2 select lists and file input) to a table.
When I click Add Row, the row is added perfectly and both select boxes along with the file field are shown as expected. The problem occurs when I select a value from the "room_name[]" box - there are no values returned inside the "album_title[]" select box. It doesn't seem to be triggering the onChange event.
code JavaScript:
function addRow(tableID) {
var table = document.getElementById(tableID);
[code]...

I want to use arrays to populate an HTML list. I can populate the main list items but I can't seem to get the sub list items to work.
<HTML>
<Body>
<ul>
<script>
var pages = ["page1", "page2","page3"];
var subPages = ["sub1","sub2"];
for(var i = 0; i < pages.length; i++){
var page = pages[i];
document.write('<li>' + page + '</li>');
if (page == "page2"){
document.write('<ul>');
for(var i = 0; i < subPages.length; i++){
var subPage = subPages[i];
document.write('<li>' + subPage + '</li>');
} document.write('</ul'>);
}}
</script>
</ul>
</body>
</HTML>

how to create a somewhat simple form. The form will have text fields for 'Name', 'Phone', etc. What I want is to have a drop down list, which has different insurances to choose from (i.e. Medical Insurance, Dental Insurance, Senior products), and say when I choose 'Senior Products', new text fields pop up within the form to add their 'Address' and click a checkbox that states they authorize to be contacted. These new fields aren't visible unless they choose 'Senior Products' from the drop down list.

Have a WAMP setup with Apache, PHP and Mysql service and I�m working on a HTML form which will have two drop-down controls where information is extracted from two tables in my DB.The first drop-down list called (name="sel_ControlArea") will decide what information the second drop-down list will have.So far I have managed to populate them when the page is loaded using PHP but run into problem when I make a change on the first drop-down list.Question one: What is the best/correct way to solve this problem?Is it to load all information into PHP arrays and then translate these to Javascript arrays, or should I go for AJAX, or XML or are there any other better ways ?I have tried to solve this using the first method, put data in a PHP array but run into problem with this data not properly loaded.This is first time for me to pose a question so please let me know if I have left out some important information or if I should describe this problem in a different way.
<table class="exemption" border="0" cellpadding="2"
cellspacing="5" bgcolor="#eeeeee">

The following PHP code populates a dropdown list of Projects. I would like to be able to click on a Project Name in the list and have its corresponding list of Characters appear beside it. How can I tie jquery into this as it's running? All the jquery examples I see are for hard coded HTML data instead of a PHP loop grabbing from a database.
Code:
//creates the Project dropdown list
while ($proj = mysql_fetch_array($project)){
$id_proj = $proj['projid'];
$name_proj = htmlspecialchars($proj['projectName']);
[Code]....
I don't care if it's a clickable list of anchors instead of a dropdown. Also, I don't care whether people have javascript enabled as this is for my personal use.

I have set up my website quite some time ago that has served its purpose very well, however I will now be adding an order form functionality. So far, by reading books and traversing forums, I have been able to develop a page where the user
1.Enters data into the required fields, that is then submitted to a MYSQL database via PHP,
2.Can retrieve orders that are stored in the database,
3.Delete orders that are stored in the database.
I have wamp installed on my computer as the webserver. I have also incorporated two drop down lists that both retrieve their values from tables within the database. The first drop down list retrieves the Australian States that I have stored in a table, and once the submit button is pressed, it stores the State that is selected to a separate table. This drop down list functions as it should. An extract from "From Place an order.php"
<?php
$dbcnx = @mysql_connect('localhost', 'root', 'tingling');
if (!$dbcnx) {
exit('<p>Unable to connect to the ' .
'database server at this time.</p>');
} .....
The second drop down list retrieves product names from a table that contains products and their prices. What I would like to happen, is that when the product is selected from this drop down list, a text box is automatically filled with its corresponding price. I had this drop down list working as per the "States" drop down list, but could not get it to auto populate the text field. I got some assistance from a friend and was able to get the text box to auto populate with its corresponding price, however when the page was submitted to the database, the "id" number of the product name from the drop down list was stored, and not the product name.
<select name="productSelection" onchange = "getProductDetails(this)">
<option selected value="1product">Select Product</option>
<?php
$products1 = @mysql_query('SELECT * FROM products');
if (!$products1) {
exit('<p>Unable to obtain author list from the database.</p>'); .....

I have created this chatroom using php and scriptaculous but I am stuck with a tiny issue which I believe is only solvable using Javascript.
I have attached 2 screen shots. 1.jpg is what I get at the moment and 2.jpg is what I want to get.
As you see when somebody sends message and the messages exceed pages size, the scroll bars appear, I need the scroll bar to be the oposite direction (down to top) like yahoo or msn or any other chat room.

I'm using AJAX to auto-refresh a chatroom. You can see it on the right of the following site: http:[url]...
The problem is, when large images are placed in the chatroom via BBCode, (temporarily disabled) when the chatroom refreshes, they flicker! This is caused by the AJAX reloading the content, which in turn reloads the image.Is there a workaround for this? I want to allow images in the chatroom, but I don't want to turn off the auto-refresh. Below is the code I am running to refresh the chatroom:
Javascript Code:

- Javascript Code
function update()
{[code]....
Basically, what it does is reloads chatQuery.php and currentlyOnlineQuery.php every 5 seconds, or when a chat message is submitted.

I'm trying to make a link harvester for this Chatroom. Because my friends post way too many links and I never get to view them all. So I was trying to make something to fix that.
Html is roughly:
My javascript was:

This is a calculator that calculates how much a user can earn from their referrals depending on the user's Level & Member type. It's supposed to be updating live (onChange) when the user types in new values in the fields, but nothing is happening. [URL].
Code:

var myLevel = eval(document.earningsform.level.value);
var memberType = eval(document.earningsform.type.value);

I own a GPT site that offers member Daily SUrveys. When a daily survey is completed, the time of completion is stored in SQL in Unix time format. I hired a guy to code a Countdown timer for me that would be placed next to every completed offer in member's panel and that would show how much time is remaining till the Daily surveys resets and becomes available to the member for completion again(Daily Surveys reset every 24 hours)
