Comment system with jQuery, Ajax and PHP.

best practice, thank you

Cool! Thank you!

The javascript is some obtrusive: when you disable javascript the form doesn't work. Better is posting to an existing page. With jQuery, you could change the action and do your AJAX thing.

hey ... this is a very good script but what i wanted to know was that if i practically add something like this on my website then where do i store my comments .. how is this script going to change. please help me with this.... waitin..

Yes where to store the comments :)

thanks for the fast reply , my mean is too keep
the comment on the page like when the comment
just come also

this character ' is transform to /

can we make clicable link from the comments ?

thanks and very good job :)

exactly what i was looking for, thanks

nmn

nice script but how to keep the comments visible ??

hello! i love the script.. so i tried to change it a bit.. can you please show me how to add an input there as file? i want to add upload file using that script... please help me...

Looks perfect, thanks.

Can I get some clarification on what I need to do in order to store my posted comments here?

Namely, a better explanation of the following:

"Comments will store in database table..

CREATE TABLE comments
(
com_id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(25),
email VARCHAR(25),
comment TEXT
);


Edit " commentajax.php " SQL Statement

mysql_query("INSERT INTO comments (name,email,comment) VALUES ('$name','$email','$comment') ") ; "

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'password';

$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');

$dbname = 'commentbox';
mysql_select_db($dbname);


Any help would be appreciated

My last comment cut off my question :S

I want to set up an SQL database to allow these comments to be saved. I have a basic knowledge of databases, but can anyone tell me how I set up the information I posted above to allow the comments to be saved?

The blog author's suggestion confused me slightly

Can anyone help me with selecting the comments from the database and displaying them in the same format? I can save them successfully but of course when you refresh the page they disappear.

::lost::

At this point I have a DB created, but even in reading everything here have no idea what I need to do next to be able to save these comments. I expected to actually see something in either comment.php or commentajax.php that asked me for the DB name, user and pass - something where'd I'd just plug these in and be good to go.

I need a "for dummies" version if someone should feel inclined. :/

hi Srinivas,

Very nice comment system , but i have one question , is it possible to make this script work in other languages such as Arabic ( right to left languages).

If so please tell me which files need to be changed...

Thanks man.

Thanks for keeping it simple. Just what I needed.

Hi Srinivas,

Can we have the final script with all the feature
request ? to be more clear im sure it's easy for you
but just for newbies like me :)

try it

How can I revert the order where the li elements are placed? They are always placed 1 under the other... I would like to put one on topp of the other.
I tried changing $("ol#update li:FIRST").fadeIn("slow");
but it didnt work...
is there another way?

Hi Srinivas,
Actually i m making a social community website. I have one problem here how can i show the comment post in the wesite once it is refreshed it is gone though it remains in the database.
Is there anything i have to do ?

What about security? When doing a comment system like this, you expose the php file that handles the post, and also the variables.

Everyone who knows php can access that php file directly, and add comments to non-existing blogs.

Is there a way to prevent this? I'm making a system like this myself, and I need som kind of security.

cool,,
thank's for the sharing...
i will try it , ,,

You should be aware that if there is a lot of content in the comment box it looks a mess. The comment crosses over into the text fields.

Surprised nobody has noticed this. Tried it on the live demo in multiple browsers

Great turtorial. But if we have a lot of comments, how should we do next for the jquery pagination? Thankx

Great explaination

how do you make this comment system to display the time when the comment was posted

hi can this be themed like facebook

Hey, Nice script m8.

But if adding this to different pages while using the same db and table's will it only display the comments based on the page ID?

I see the post above and the additional table instructions but have yet to see if anyone actually got it working.

Any additional info would be greatly appreciated. Thanks :)

You should really make this a more complete script.
Its got great potential but its missing too many required pieces to be a viable option for anyone other than dev's.

Make a simple config file for mysql and include it with the download. It should also be built assuming people will be using it on multiple pages thus the post_id should be included by default.

hi can you explain the jQuery.js?


-oscar

thank you Srinivas Tamada,

i just have another question how can fix the comment msg it overflows in the div i want it to be align on the div or if you have a final sourcecode can you share it to me im working on my personal page im just testing in at localhost..do you have email?thnx

Srinivas u r too gud yar... was looking fr the same thing



Preeti

Nice!

can i do pagging? in this script

Hi Srinivas,
Thanks for the script. I tried what you proposed to put one comment on top of the others

$("ol#update li:first").fadeIn("slow");

But it doesn't work. I can display the first comment but the others doens't appear. Can you help me?

thanks ya..

Awesome! It works great. Thanks Srinivas

Great Work

I can't see anywhere your mysql_close(); statement if you are to create tables in your database. Do you keep it opened and lying like that all the time just for everybody to access?

Hello Srinivas,

I am lost on how to keep the old comments. What code and WHERE will I put it????

I am new to PHP and MySQL but very much interested in your work.

Hello Srinivas,

I am lost on how to keep the old comments posted and how to delete the old comments. What CODE and WHERE will I put it????

I am new to PHP and MySQL but very much interested in your work.

Many thanks!

Arnold

Hi Srinivas,

All of us appreciated your work! Many thanks and keep it up.

Can you post here the complete COMMENT SYSTEM you have done.

Because for newbies like me, I am kinda loss with all additional codes. Like displaying the old comments, where to put the code, etc.

Again, thank you!

Great Work

Hey, nice script.. with easy understanding :-)

thanX
Manjula

thank you! very good!

Was wondering; the comments show above the form. How about making it into the reverse and have the comments show below the form. This format might be needed if just a single field is to be filled in. Think of something like Facebook's share form.

good job

Thanks very nice

NICE!!!!!!

Cool!

PS: Why are the comments dissappearing when you go in to the page again?

Great script, but when you put a blank space( hit spacebar) in textarea, you can still post a blank comment. How to fix that ? Tnx

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/a5530317/public_html/coment/comment.php

what this mean?
how to fix please

Wow great example i have edit it and it now shows comments has an captcha and posts to a DB also it works on multiple pages remembering wich page it has been posted to !!

is this an example of the system itself?

i love your script, you made me want to learn ajax now :)

excelent

Very cool

Wow, this is awesome!

I’ve implemented this and it works great. However, I’m having a hard time implementing multiple comment boxes on a single page. The best way to describe what I’m doing is to think of a twitter stream, and the users having the ability to view comments and add comments on each individual tweet. So I added another column to the comments table called item_id which will reference which item this comment belongs too. I’m not sure how to implement this though…..any help is greatly appreciated!!

thanks i like it...

thanks

The comment system is great when used in conjunction with JQuery,Ajax,CSS and PHP

cool

Awesome I'll give it a try, got a complete account/profile settings system ready, people can sign up, log in and out alright. Now I'm going for how the site is gonna work.
Can't believe people are still using IE, it's such a pain in the ass to make the site compatible, not sure I'll do it anytime soon.
btw I'm following you on twitter ;)

Very cool!

cool

Excellent. Can't wait to give this a go, thanks.

Nice job

good

Hi Srinivas,

How could i make this automatically update ? I can store the values, i can display them, but i would like to refresh the page everytime a new comment is added ( basically a chat function .. ). Any sugestions? Your help is greatly appreciated :) Thanks!

Hello again, i have figured this out on my own. It's not the best solution, but this is my add :
in commentajax.php , instead of listing the last comment, you put the code to list all comments.

then, in your comment.php file, you create a function (ex: show_content() ) which contains the $.ajax code, without the data parameters. at the end of this function you add setTimeout("show_content()",2500); (2500 meaning 2.5 secs to refresh). You would need to clear the innerHTML of the update div, and remove the getElementByID('comment')="" statement, and than this can be used as a chat.

The instructions are short, but i can provide you the files so you can write more detailed instructions :) i'm sure people will be gratefull. My email is freecubex@yahoo.com (maybe you won't make this public,please!). Thanks!!!!
Alex.

nice. this is helpful

Hello,

Nice Comment System

nice pretty cool but need to finish

Nice comment box script. I might have to work on one myself.

I have added this code to my streamline, however after it posts the comment, I cannot get the text area to clear. Any thoughts?

very interesting cods thanks a lot

you chose to make a click event on the submit button, it would be more intereting to use an onsubmit event listener...

Firts of all thanks for the script im new to js and jquery so as ajax, is very simple and understandable. I have a site with several posts on a single page, i want to add comments to every single one of them, how can i tell the script which form is been submited?

Thanks!

thank!

wow

thank you

Thanks man !!!

Good work!

Thank you for this script. But I have one question - how can I add more fields. I make everything to works fine but I can not make show post_id. I try to add input hidden field with post_id and after that i try to access it with $_POST[post_id] but... it's not working. I try to add one row it in the JavaScript:

var post_id = $("#post_id").val();
var name = $("#name").val();
var email = $("#email").val();

But it still not working :) Any suggestions?

cool..........

Nice

Looks good!!!

Pls can someone upload the working code and maybe post a link? is that possible here?. I really like this script, but it must be full of typo's or bugs judging by what people have commented on. Its an excellent looking comments system.

Kev

good one...

how do i retain the comments while the page refreshes?...please any good assistance will be appreciated..thanks *

###You can add more fields###
Just change the Id element name to your desired..and feel happy
################################

$(function() {
$(".submit").click(function()
{
var name = $("#name").val();
var email = $("#email").val();
var comment = $("#comment").val();
var Id = $("#actID").val();
var dataString = 'name='+ name + '&email=' + email + '&comment=' + comment + '&actID=' + Id;
if(name=='' || email=='' || comment=='')
{
alert('Please Give Valid Details');
}
else
{
$("#flash").show();
$("#flash").fadeIn(400).html('(insert your loading image here)Loading Comment...');
$.ajax({
type: "POST",
url: "commentajax.php",
data: dataString,
cache: false,
success: function(html){
$("ol#update").append(html);
$("ol#update li:last").fadeIn("slow");
$("#flash").hide();
}
});
}return false;
}); });

it is great article.

is this script working with mobile web browsers?

Nice script.

Hi guys See this PHP script:-

this script is good but has one major problem which i think most people would prefer to have, and that is to have the comments stream always display, and not just display when a comment is sent

good nice

does this comment goes directly or goes for approval first?

Nice sript, thanks man ! Just be good to add some function for paginatin comments - if we have moor comment about this article ?
But, again, thanks man !
