Very Simple Chat Room
I would like to set up a very simple chat room for my daughter to use with her friends. I am reasonably competent in PHP and MySQL and was wondering if anybody could suggest a simple way to create a script.
The obvious way using what I alredy know would be to have the page auto refresh at regular intervals but I can think of several disadvantages of having the chat updated in this way. Is there an alternative way to update new message without refreshing the whole page?

Chat Room Needed
I'm in a need of a chatroom for my website, and I'm assuming PHP would be the best option. There is one feature I must have: I need to be able to assign a user mod powers so any time he logs in, he'll have that power. I also would like for his text to show up in a different color than everyone else's.

Small Bug With My Chat Room.............................................. .....
Take a look at PHP chat with no login screen! Try changing your alias from guest, and click the SEND button, it works. But change it and then press ENTER and the input frame dissapears . This is the main parts of the message and alias text boxes, they are in different forms, how can I stop it going blank when people hit enter? ************************************************** ** <FORM NAME="MsgForm" ACTION="<?php echo($action); ?>" METHOD="POST" AUTOCOMPLETE="OFF" TARGET="<?php echo($target); ?>" onSubmit="return window.parent.validateSubmission();"> <INPUT TYPE="text" NAME="M" SIZE="45" taborder=1 tabindex=1 MAXLENGTH="299" VALUE="<?php echo(htmlspecialchars(stripslashes($ValM))); ?>"> <INPUT TYPE="hidden" NAME="sent" VALUE="0"> <INPUT TYPE="submit" NAME="sendForm" VALUE="<?php echo(L_OK); ?>"> </FORM> <form name="aliasform"> <INPUT TYPE="text" NAME="ZU" SIZE="5" MAXLENGTH="29" VALUE="<?php echo(htmlspecialchars(stripslashes(urlencode($U))) ); ?>"> </form> ************************************************** ** Can I detect if they hit Enter while in the alias text box, then set focus somewhere? Its like it submits a blank form and goes nowhere. is there a setting I can use on <form name="aliasform"> to stop that?

Simple Room Booking App?
I'm lazily looking for a simple app that will let us match up teachers, classes, and instructors, preferably with a php/mysql infrastructure so that it's accessible via the web. If there is a single good repository of free scripts that would be useful as well.

Chat Function That Allows Users To Seek Help Via Live Chat
I found that some of these pre-made help desks also have a live chat function that allows users to seek help via live chat, similar to aim. (Once you log into the help desk at php live, click on the "launch request monitor window" to get a better understanding of what I am talking about.) Unfortunately, I showed this to my boss and he liked that idea. Why unfortunate? I have no idea where to start on this one! I have done several web apps with php and mysql, so I would say I have a fair grasp and understanding, but this one has me stumped. Has anyone done something similar to this or have an idea in which direction that I need to be going?

Checking Room Availability For Hotel Booking System
I was wondering if anyone could help me with a problem I'm having. I've been using Dreamweaver to create a hotel booking system for a friend of mine, using MySQL (version 4.0.21) and PHP 5. The bit I'm struggling with is checking the Room Availability based on dates that are typed into a textfield and then returning a list of the available rooms on the next page. The three tables involved in this function are: CREATE TABLE `room` ( Room_Number tinyint(1) UNSIGNED NOT NULL, Price_Double_per_Night decimal(5,2) NOT NULL, Price_Twin_per_Night decimal(5,2) NOT NULL, Price_Single_per_Night decimal(5,2) NOT NULL, Price_Double_per_Week decimal(5,2) NOT NULL, Price_Twin_per_Week decimal(5,2) NOT NULL, Price_Single_per_Week decimal(5,2) NOT NULL, PRIMARY KEY(`Room_Number`), ) TYPE=InnoDB ROW_FORMAT=fixed; CREATE TABLE `room_booking_link_entity` ( Room_Number tinyint(1) UNSIGNED NOT NULL, Room_Booking_ID int(11) NOT NULL, Single_Double_Twin enum('Single','Double','Twin') NOT NULL, PRIMARY KEY(`Room_Number`, `Room_Booking_ID`), INDEX `Room_Number`(`Room_Number`), INDEX `Room_Booking_ID`(`Room_Booking_ID`), FOREIGN KEY `Reference_14`(`Room_Number`) REFERENCES `room`(`Room_Number`) ON DELETE NO ACTION ON UPDATE NO ACTION, FOREIGN KEY `Reference_85`(`Room_Booking_ID`) REFERENCES `room_booking`(`Room_Booking_ID`) ON DELETE NO ACTION ON UPDATE NO ACTION ) TYPE=InnoDB ROW_FORMAT=fixed; CREATE TABLE `room_booking` ( Room_Booking_ID int(11) NOT NULL AUTO_INCREMENT, Customer_ID int(11) NOT NULL, Bill_ID int(11) NOT NULL, Date_of_Arrival date NOT NULL, Date_of_Departure date NOT NULL, Number_of_Nights tinyint(3) NOT NULL, Date_Booking_Made date, Status_of_Booking enum('Booked','Arrived','Departed') NOT NULL, Total_Cost decimal(7,2) NOT NULL, PRIMARY KEY(`Room_Booking_ID`), INDEX `Room_Booking_ID`(`Room_Booking_ID`), INDEX `Customer_ID`(`Customer_ID`), INDEX `Bill_ID`(`Bill_ID`), INDEX `Date_of_Arrival`(`Date_of_Arrival`), INDEX `Date_of_Departure`(`Date_of_Departure`), INDEX `Status_of_Booking`(`Status_of_Booking`), FOREIGN KEY `Reference_03`(`Customer_ID`) REFERENCES `customer`(`Customer_ID`) ON DELETE NO ACTION ON UPDATE NO ACTION, FOREIGN KEY `Reference_14`(`Bill_ID`) REFERENCES `bill`(`Bill_ID`) ON DELETE NO ACTION ON UPDATE NO ACTION ) TYPE=InnoDB ROW_FORMAT=fixed; I've just discovered that MySQL 4.0.21 does not support subqueries. I'm basically stuck with this version of MySQL. I think I've got round the subquery problem by using a multi query option as follows: 1.Create a temptable that will store all of the room numbers that have bookings for the particular dates requested as follows: SELECT DISTINCT a.room_number INTO temptable FROM booking_link_entity AS a INNER JOIN room_booking AS b WHERE b.departure_date >$_POST[‘ARRIVAL'] And b.arrival_date < $_POST[‘DEPART']; 2.Left join this with the room table and pull out rows with no match SELECT a.room_number, b.room_number FROM room AS a LEFT JOIN temptable AS b ON a.room_number=b.room_number WHERE b.room_number IS NULL; 3.Delete temp table I've tried doing this in Dreamweaver, but to no avail. I have a feeling it is too complex for Dreamweaver. My php knowledge is very basic and was wondering if anyone could give me some pointers as how to do this in PHP?.

Php Chat
i have made a chat script that uses META REFRESHES to update from a flat txt file. this is very inefficient for both server and user. the problem is i can't think of any other way to do it. one way i can think of is to open sockets so that a server can look at the file and see if it has been changed. of course, i have no idea where to start, so instead i built a really bad script that was worse on the client (i.e. 100% CPU usage) but not so bad on the server. any ideas?

Chat
I'm about to write a small chat application. To keep the flow of new messages coming, two things are possible. The first is to use a hidden frame, and to reload it every couple of seconds. The second would be to keep open the connection in the hidden frame (so the page is never realy loaded). I would prever the latter, but don't know how one keeps open the connection. What happens if the user closes the browser?

Simple Script For Doing A Simple Photo Album And Journal?
I'm looking to quickly get a photo album online. Very simple, thumbnails, a few pages, maybe a description, but hopefully a small script that's easy to edit and work into my existing site. I know about hot scripts, etc. but I was wondering if any one could recommend one? Secondly, I also want to setup a journal. It's not really a "blog" although I guess blog software may work. But it isn't going to be a message board or anything like that. Just a place to put out random bits of news. Once again, same premise, I'm trying to find the most simple script possible that could basically traverse a directory of simple textfiles and produce a list. I know all about Blosxom and stuff like that, but I'd like a script that just did the above and didn't overtake my site like PHPNuke or something like that. I'll probably roll my own, but I thought I'd check first.

Chat Whispering
I'm working on making a chatroom, using php and mysql. I'm new to php and mysql, so this might be a stupid question, but how do I make a chat whispering? is it just if ($username == $whisperto) { echo "Hi, I'm whispering to you"; } else { echo " "; } I know I'm doing somehting wrong, just not sure what it is. And also, what I need to create also for the chat whispering, is if you want to whisper to someone, you click on their name, and it will put in a text box who you are whispering to. I'm not sure what its called, so I'm not sure how to do that. Like they have there, you click on one of the smilies, and it puts the little code into the typing area.

Building A Chat
'm trying to build a small chat in PHP, but i'm having some slight problems and need some help. first off, I want to use emoticons, and I want to use the str replace code to make it work, but it doesn't... $smile = str_replace(":)", '<img src="c001.gif">', "$msg"; $msg being the $_POST of a text field (I use a txt file with fwrite to build the chat) can anyone tell me what i'm doing wrong ? also, I want to be able to see how many users are connected to the page, without using MySQL. Can anyone guide me on how I can do this? I already have each user login and it creates a $_SESSION['username'] so i'm guessing I can make it work..

Chat-like Non-buffered Output
I would to like to output html data like in a HTML chat - that means line by line. As soon as I send a line to the client it shall appear directly (continuously), not when the whole document is completed. I need that for some sort of progress indication. So how can I force the browser to output contents before the document has been completely transmitted - like in a HTML chat? Do I have to send some special HTTP header(s)?

Chat And Instant Message
1. Does anyone know of any good chat software? I was looking for something that looks similar to digichat chatrooms and allows setup of multiple rooms. 2. How would I implement instant messaging on my website. You have probably never been on blackplanet or collegeclub before. But I want users to be able to IM each other on the website when they log-in to the site. It is built-in. I was hoping to use something plug-in based, maybe something similar to AIM Express, so they don't have to download the client when they log on from different computers. I think MSN Gaming zone used to have a built-in IM before MS started making everything a part of passport.
