Web Based Chatting App (AJAX + PHP)

Apr 9, 2007

I am looking for people's opinions on if this is a good model for my chatting application or if they have any suggestions on a better and quicker way to do it.

I am making a web bases chatting application that is using PHP server side scripting. I plan on using AJAX to bring about the live chatting feel. I have already written most of my custom AJAX scripts. Currently I am storing the chat in a log file instead of using MySQL database (my hope is that the file system will perform faster). I have a text file that basically holds a few bits of information in groupings. One grouping may look like this:

msg:this is a test message

Each log file will have many of these, which is the chat for a given chatroom. My idea is to have PHP read the file in and display any new chats to the user. I want to be sure that this log file doesn't get too large so I was thinking I would only store a certain number of messages in the log file. So one of my questions, is there an easy way to remove some of the log file at the beginning of the file and keep the rest of the file intact?

AJAX Based Forms Generator

Jan 3, 2006

I've looked a lot at phpMyEdit and it is decent for throwing up a very quick php form for editing a table in a mysql db. Especially nice would be one which uses AJAX technologies and automatically generates as much of the code as possible. With phpmyedit I'm finding it difficult to retrofit in the stuff I want. Not sure where to post this, it isn't really php specific as I don't care if it is python, perl, php, but, since I've been using phpmyedit i figured in the php forum.

Handle Redirection In An Ajax Based Application

Jan 2, 2011

I'm developing a Ajax based php application. As anybody knows, I'm checking whether user is logged in every php file as the first statement. And there are two ways that I should response in an event of logging failure,

server redirect to the login page using header(url). CASE: If user directly enter a particular URL passing url in Ajax response asking client side page redirection or notification CASE: If user trying to perform some action through a Ajax request

So my question is how can identify whether request coming from client side is a Ajax call or not ? If I know that I can handle my response accordingly.

Computing Result Based On Two Different Ajax Request?

May 27, 2011

i have a simple form with two fields whose data are being validated against a database on keyup with jquery. I am also having a button which is currently enabled or disabled based on the number of characters entered in these two fields. THe two jquery functions return an "accept" or "cancel" image for the two fields. I want to enable the button only if both the functions return the accept image or i can even make them return true along with it, which will not be a problem. I just wanna know how to compute a local result based on the returned value from two different ajax requests.

These are two functions that validate teh field against a database.

var agentName = $("#agentName").val();
if(agentName.length > 3)
$("#agt-name-result").html(ajax_load).load(loadUrl, "val="+agentName+"&fld=agent_name");

Initialize And Handle SESSIONS In Ajax Based Application

Jan 28, 2009

Ideally in ajax based application, when a user logs in successfully , then user has to be redirected to secured pages [secured by SESSION check], but Iam facing a problem that even successful logins, I am redirected to login page.

Following is my Server side code

PHP Code:



As per above mentioned codes, if I get 'MsgType == A', even then I am redirected to login page. But I want to be redirected to secure page [main.php], after successful login.

Note: Secure page [main.php] is validating SESSION variables. If SESSION variables exist, then secure page is opened, otherwise user is redirected to login page.

So in my opinion, there is a problem with SESSION in AJAX. Without ajax, this application is running fine.

Comet - Best Approach For A Scalable AJAX Based Chat System?

Mar 19, 2010

I'm building a chat system for a company and I'm wondering as to what the best way to build the system would be?The current setup we have is a Nginx HTTP Server with PHP and Memcacheq (as a message queue that appends the chat messages to the user's own queue). We then poll the Nginx server (through a Comet style request) and query the message queue for updates.Is it a good idea to use a message queue such as Memcacheq to handle a chat system that has both user-to-user and site-wide chat or is it best to just stick to MySQL?

Stop A Form Load Based On The Return Data From An Ajax Callback

Nov 18, 2010

I am working with an ajax post function, where I send data and my callback from PHP returns some data back. Based on the data returned I make the decision, either to go forward or allow the user to stay on the page and make changes.

if (validateStep(step))
var data = document.getElementById('hiddenContact').value;
$.post('/app/controller/action', {'data':data}, function(returndata){if(returndata.match('not Unique'))alert('Contact source already exists'); else if(returndata.match('not posted')){alert("Not posted to the database");return false;}});

Here I am trying to stop the application going ahead when the return data is matched to "not posted", and I am throwing an alert and then a return false to stop the operation. I am unable to stop the application from going to next step though. Though it is returned false, the operation continues to the next step, but when I comment the last 4 lines which increment the step, set the action and submit, it stays on the page and the alert is thrown.

Web Crawler PHP

Nov 2, 2006

I am supposed to construct a page that searches in specific websites to extract information, like those sites from where you can rent a car for example. There is a form in the site where the user selects some fields (for instance departure and drop-off date), then the data are submitted to the other page that searches 2-3 sites and finds which cars are available on those dates.

I wanted to ask if there are ready scripts to do that, if not, some hints on how to start. I am familiar with PHP forms and data extraction from mysql databases, but when you extract data from other sites, I have no clue how I can begin and deal with it...

Keep Crawler In One Domain?

May 21, 2011

I'm writing a simple php crawler, essentially a class which recursively crawls the website by detecting link tags and going deeper. The problem is that I would like to contain it within the domain it's crawling, otherwise it will start following links to other domains and start a never ending chain reaction. My idea was to scrabble a regex that would dissect the bare domain name of the website (eg. and check every link against it. The regex itself will have to be quite long, since I will have to include all TLDs in it.

UPDATE: parse_url is not a solution - only can give HOST name not DOMAIN name.

Checking If Referrer Is Web Crawler

Jun 28, 2006

I have a book affiliate website. Whenever a visitor clicks on one
of the books, a script adds one to a field in a mysql database and then
takes the visitor to the shopping basket on the book website.

I have noticed that the book links are getting lots of hit. At first, I
was pleased about the potential income this might mean - but then it
occurred to me that many of these hits are web crawlers (this was
confirmed by webaliser).

Any suggestions of ways of checking if the link is being "clicked" by a
webcrawler so that I can not increment the field in the sql database?

I've checked HTTP_REFERER but it seems to be empty for what I assume
are crawled clicks.

Web Crawler For Competitive Pricing

Jan 18, 2011

I am thinking of writing an application that will pseudo-track competing websites to ensure that our prices stay competitive, etc. I looked at possibly using the Google Shopping Search API, but I felt that it could possibly be lacking in flexibility and not all of our competitors are fully listed or updated regularly. My question, is where is a good place to start with a PHP based webcrawler? I obviously want a crawler that is respectful (even to our competitors), so it will hopefully obey the robots.txt and throttling. (To be fair, I think I am even going to host this on a third party server and have it crawl our websites to show no biases.) I looked around via google and I couldn't find any mature packages -- only some poorly written sourceforge scripts that haven't been maintained in over a year, despite being labeled as beta or alpha.
