PHP - My Own Realtime Chat Script
Hello everyone, im new here. so to begin with i wanted to ask you about my realtime chat script im creating. You can check it out here http://madnet.us.lt/chat.php. Please! i repeat PLEASE, dont use any tags or sumtin in input fields, the chat is still unsafe! It only works in some versions of Opera, Mozila(best) and i think it should work on Chrome, but god no ,dont use IE This is my first
project i created so dont judge me if the code sounds stupid to you:D I made this using php/html/jquery and css . My first problem is that i used timeout function for chat div refresh, i dont think its the best way to get data from mysql, couse if like 500 or more people will get refreshes every 1 second, i think the server would crash, maybe you could get me through this with an alternative. Another problem is as i mentioned before that this chat is not capable with all explorers people use today. Third problem is that i cant figure it out how to make the public and clan buttons work (i only manage to get one of them work, if i make another one work then they conflict(nevermind you will see in the code)). I got a lot of more questions about security and stuff. but for now i would like to get the answers how to fix these things. Now il share you the code. I will accept all you advices so be free to say anything you think would be better for my real time chat. Im attaching the chat files.You will find the mysql tables in the zip Many thanks! [attachment deleted by admin] Similar TutorialsCan anyone suggest some good php Script(or Weburl) to do chat part in my php system please...

Any help please... If I send normal messages I don't get any errors...i am new with web socket
and in same time
I try to make server and client communication for soccer manager application, and for this purpose, i need to create closed "chat rooms" or "games" where two users can watch (read game event) and menage (create) game event (make substitution, formation ... or if you want, to send message to server, that they make changes in formation)
this game (room) mast bi secret, and only this two player can use this game for "read" and "write" events in game
for example: Game no: 200001 between user A and user B in 14.05.
when User A, and User B click on game no. 200001 they can read and write game event.
PS: for now, i create basic chat aplication with PHP, jQuery and webSocket and in this app, all user see wath all other user do (public chat) and i want to make secret chat for specific user (already automate subscribed from server) All work with no problem (i work on this example http://www.sanwebe.c...ket-php-socket)
How i can create chat room(s) and subscribe user to specific chat room?
Thanks

I'm trying to get it so when somebody is logged in, and posts something in the chat area, it displays: [Name] [Comment] I know how to read from the database, but for some reason, when I press the 'submit' button, the text in the 'comment' box isn't inserting into my 'comment' column in my database...

Please tell me any known or good script. thanks I am not sure how I should go about doing this. I have a server that has a chat server on it, people register an account and then have access to this chat server from their application. To initially connect to it, they need a game id and game stamp (kind of like a username/password for the game). I don't want chats from one application to display in another users application. When I created this chat server it was for another purpose, and could only support about 64,510 different chats since each chat ran on its own port. For my current purpose it is a little different some applications can have 1 - 10 chats going at once per user using the application. Say their is 100 people using the application and each is using 5 - 10 different chat windows. With 100 users on at the same time all chatting, that can get up to 1,000 different ports being used. I don't want that, because say there are 100 applications also using chat, that is about 100,000 different ports, and I am pretty sure you cant have 100,000 ports. So! I need a way to make a chat server, any ideas on how I could do this with my php? need more information? please ask! My database name is cute and in cute database contain chatmessages and ipbans tables in which chatmessages contains id(auto increment), name, IP,postime and message and here is the form2.php coding form 2.php Code: [Select] <?php mysql_connect("localhost","root") or die(mysql_error()); mysql_select_db("cute") or die(mysql_error()); $message=$_POST['message']; $n=$_POST['username']; $name=$_POST['name']; if(isset($_POST['submit'])) //if submit button push has been detected { if(strlen($message)>1) { $message=strip_tags($message); $IP=$_SERVER["REMOTE_ADDR"]; //grabs poster's IP $checkforbanned="SELECT IP from ipbans where IP='$IP'"; $checkforbanned2=mysql_query($checkforbanned) or die("Could not check for banned IPS"); if(mysql_num_rows($checkforbanned2)>0) //IP is in the banned list { print "You IP is banned from posting."; } else { $thedate = date("U"); //grab date and time of the post $insertmessage="INSERT into chatmessages (name,IP,postime,message) values('$name','$IP','$thedate','$message')"; mysql_query($insertmessage) or die("Could not insert message"); } } } ?> <html> <head> <script type="text/javascript"> function addsmiley(code) { var pretext = document.smile.message.value; this.code = code; document.smile.message.value = pretext + code; } function a() { var x = document.smile.message.value; if(x=="") { alert("Please insert an message!"); return false; } } </script> <style type="text/css"> body{ background-color: #d8da3d } </style> </head> <body> <form name="smile" method="post" action="form2.php" onSubmit="return a()" > Your message:<br><textarea name='message' cols='40' rows='2'></textarea><br> <img src="smile.gif" alt=":)" onClick="addsmiley(':)')" style="cursor:pointer;border:0" /> <img src="blush.gif" alt=":)" onClick="addsmiley('*blush*')" style="cursor:pointer;border:0" /> <input type="hidden" name="name" value="<?php echo $n;?>"> <input type='submit' name='submit' value='Set Name' class='biasa' ></form> <br> <br> </body> </html> my problem is if the first chat message that i click submit button it would be appear name:message but when the second time submit it only appear the message but the name is blank(nothing and empty) This is my login.php Code: [Select] <?php mysql_connect("localhost","root") or die(mysql_error()); mysql_select_db("Regis") or die(mysql_error()); if (isset($_POST["sub"])) { $_POST['pass'] = md5($_POST['pass']); if (!get_magic_quotes_gpc()) { $_POST['username'] = addslashes($_POST['username']); $_POST['pass'] = addslashes($_POST['pass']); } $usercheck = $_POST["username"]; $check = mysql_query("SELECT username FROM registration WHERE username = '$usercheck'") or die(mysql_error()); $check2 = mysql_num_rows($check); //if the name exists it gives an error if ($check2 != 0) { echo("<SCRIPT LANGUAGE='JavaScript'>window.alert('Sorry, the username" ." ".$usercheck." ". "is already in use.')</SCRIPT>"); echo ("<SCRIPT LANGUAGE='JavaScript'>setTimeOut(window.location = 'registration.php',1)</script>"); } else if($_POST['username'] && $_POST['pass'] && $_POST['pass2'] ) { $insert = "INSERT INTO registration (username, password) VALUES ('".$_POST['username']."', '".$_POST['pass']."')"; $add_member = mysql_query($insert); echo("<SCRIPT LANGUAGE='JavaScript'>window.alert('Registration had been succesfully added :)')</SCRIPT>"); } } ?> <html> <head> <script type="text/javascript"> function a() { var x = document.login.username.value; var y = document.login.pass.value; if(x==""&& y=="") { alert("Please insert all message!"); return false; } if(x=="") { alert("Please insert an username!"); return false; } if(y=="") { alert("Please insert an password!"); return false; } } </script> </head> <body> <table border="0"> <form name="login" method="post" action="form2.php" onsubmit="return a()"> <tr><td colspan=2><h1>Login</h1></td></tr> <tr><td>Username:</td> <td><input type="text" name="username" maxlength="40"></td></tr> <tr><td>Password:</td> <td><input type="password" name="pass" maxlength="50"></td></tr> <tr><td><input type="submit" name="submit" value="Register"></a></td> <td><input type="submit" name="submit" value="Login"></td></tr> </form> </body></html> So how to make when the second and next submit click button, it would appear name with message ?[/b] I've been trying to think of the best way to build a PHP based chat room. Obviously a push method would work the greatest but I have been unable to find any such techniques using PHP so this is the only alternative I can think of. When a user logs in to the chat, a file is created in a secure directory on the server for the user. This file will store messages to be sent to the user. Each time someone sends a message to the chat, the message is inserted into every user's file. Then, using AJAX, the user in chat will "reload" the chat every few seconds, which will simply access a PHP script that reads the file, sends it to the user, then truncates the file contents to zero. My concern is obviously the high frequency of server loads to access the chat file, but this is why I would try to minimize the server's effort for retrieving chat content and focus the efforts more on sending messages since this action is done less often. I'm looking for suggestions on what would be best to keep the system efficient... maybe some ideas of headers to send which may help with optimization. Thank you for your time. |
