NET Framework Version 4. Ad HTML5 apps are quite possibly the future of the web.

Un Chat para tu Web - Recientemente hemos sacado el que entre otras, ofrece esta posibilidad de adaptarlo al tamaño que realmente se desee o necesite para cubrir esa necesidad en nuestra página, a la vez que presentará una menor carga de recursos en los equipos de los usuarios. Lastly, we close our file handle using fclose.

In this tutorial we will be creating a simple web-based chat application with PHP and jQuery. This sort of utility would be perfect for a live support system for your website. Or you could to help you. Otherwise, learn how to build one yourself in this tutorial. Introduction The chat application we will be building today will be quite simple. It will include a login and logout system, AJAX-style features, and will also offer support for multiple users. Step 1 : HTML Markup We will start this tutorial by creating our first file called index. In the head tag, we add our title, and link to our css stylesheet style. We will have three main blocks: a simple Menu, our chatbox, and our message input; each with its respective div and id. The first will be a welcome to the user and will float left and the second will be an exit link and will float right. We also include a div to clear the elements. We will load our log from an external file using jQuery's ajax request. We will first link to the Google jQuery CDN, as we will be using the jQuery library for this tutorial. Our second script tag will be where we will be working on. We will load all of our code after the document is ready. Step 2 : CSS Styling We will now add some css to make our chat application look better than with the default browser styling. The code below will be added to our style. As you can see above, we are finished building the chat's user interface. Step 3 : Using PHP to Create a Login Form. Now we will implement a simple form that will ask the user their name before continuing further on. We then use an if and else statement to verify that the person entered a name. One thing that you may want to pay close attention to, is that we have used the htmlspecialchars function, which converts special characters to HTML entities, therefore protecting the name variable from become victim to. We will later also add this function to the text variable that will be posted to the chat log. Showing the Login Form In order to show the login form in case a user has not logged in, and hence has not created a session, we use another if and else statement around the wrapper div and script tags in our original code. On the opposite case, this will hide the login form, and show the chat box if the user is logged in and has created a session. We still need to allow the user to log out, and end the chat session. If you can remember, our original HTML markup included a simple menu. Let's go back and add some PHP code that will give the menu more functionality. First of all, let's add the users name to the welcome message. We do this by outputting the session of the user's name. Welcome, In order to allow the user to log out and end the session, we will jump ahead of ourselves and briefly use jQuery. If the user confirms the exit, therefore deciding to end the session, then we send them to index. This simple creates a variable called logout with the value of true. If the variable has been passed via a url, such as the link mentioned above, we proceed to end the session of the user's name. It will say that the user has left the chat session. We do this by using the fopen , fwrite , and fclose functions to manipulate our log. Please note that we have added a class of 'msgln' to the div. We have already defined the css styling for this div. After doing this, we destroy the session, and redirect the user to the same page where the login form will appear. Step 4 : Handling User Input After a user submits our form, we want to grab his input and write it to our chat log. In order to do this, we must use jQuery and PHP to work synchronously on the client and server sides. This can be achieved with the val function, which gets the value set in a form field. We now store this value into the clientmsg variable. This sends a POST request to the post. It posts the clients input, or what has been saved into the clientmsg variable. Please not that the code above will go into our script tag, where we placed the jQuery logout code. Our goal now is to grab this data, and write it into our chat log. To do this we open the file with the mode on the fopen function to 'a', which according to php. If the file does not exist, attempt to create it. We then write our message to the file using the fwrite function. It will contain the date and time generated by the date function, the session of the user's name, and the text, which is also sorrounded by the htmlspecialchars function to prevent from XSS. Lastly, we close our file handle using fclose. Step 5 : Displaying the Chat Log log. The only thing left to do is to display the updated chat log to the user. In order to save ourselves some time, we will preload the chat log into the chatbox div if it has any content. This request not only allows us to send and receive data throught the form without refreshing the page, but it also allows us to handle the data requested. You will see why in a second. As you see above we will only use three of the jQuery ajax request objects. We will use our chat log's filename of log. It will ensure that we get an updated chat log everytime we send a request. As you see, we then move the data we requested html into the chatbox div. Auto-scrolling As you may have seen in other chat applications, the content automatically scrolls down if the chat log container chatbox overflows. We are going to implement a simple and similar feature, that will compare the container's scroll height before and after we do the ajax request. If the scroll height is greater after the request, we will use jQuery's animate effect to scroll the chatbox div. If the newscrollHeight is greater than the oldscrollHeight, we use the animate effect to scroll the chatbox div. Continuously Updating the Chat Log Now one question may arise, how will we constantly update the new data being sent back and forth between users? Or to rephrase the question, how will we continuously keep sending requests to update the data? This function will run our loadLog function every 2. Finished We are finished! I hope that you learned how a basic chat system works, and if you have any suggestions on anything, I'll happily welcome them. This chat system is a simple as you can get with a chat application. You can work off this and build a multiple chat rooms, add an administrative backend, add emoticons, ect. The sky here is your limit.
