Waiting for the FLV version

oops
I replied by mistake
Sorry

thanks for tutorial its really wonderfull

This is an amazing tutorial. I will make some amazing stuff with this.
Thanks very much..

Great, thanks! Haven’t done the complete screencast yet – wouldn’t let this opportunity to be one of the first to comment pass by.
Anyway, I’m still pretty new to Ajax, but will take some time to figure out how I can add this functionality into the WordPress theme I’m creating.

Hey Jeff,

I am watching this right now but the buffering is killing me and the player does not allow me to forward through to a part that was not download. Any way for a non-iTunes download link?

very nice thanks post

Good one Jeff!

Loved the animations, and thanks for the loader page

its a good video ! but a little large

Just what I was looking for..

very nice thank…

Thanks,
this is very helpful

Nice Tut. I just wondering when next Codeigniter tut will be available

That’s an awsome tutorial.

I can’t wait until someone does a tutorial on those sliding navigation bar. The ones that the highlight object follows whatever is hovered over and when you click it, it stays.

I want to create a template with that in it.

If you know of one send me a link to info@lavishimage.com.

Nice!

But isn´t the isset($_POST[$key]) at 13:30 in line 7 somehow unneccesary because items only show up in the $_POST Array if they are set!?

Great work Jeffrey, I’m glad PHP-Tips could be of some inspiration. The effect comes built in with the theme for the CMS (chyrp), so sadly, I can’t take credit. Way to take it to the next level!

Does anyone else have trouble with the video player? Every time I try and scrub forward the video just fades out and it shows the replay button. I have to watch the whole thing beginning to end.

Hi,

You should check if the POST value exists … otherwise it will give a warning

Solution:

It will check if there is any POST value submitted with the key”field”. If it exists it will show the value of the POST array otherwise it will display “Your name here” in the textbox.

$var1 ? $action2 : $action1;

Is the same as:

if( $var ){
$action2;
}else{
$action1;
}

If you don’t get any warnings and you don’t using this method, or any similar method you probably turned of the php warnings. To turn these on check your MAMP/WAMP settings or use above the page.

Thanks Mr. Jeffrey Way

Note: we miss the code igniter tutorials from scratch xD .

Hi Jeff,

Another great tutorial!
You know that problem you were having with the “li” item withing the “ul#comments” when you slid it down it would jump, well you fixed it by defining the height in jQuery, but all you need to do is define a width for the “li” in the stylesheet and that resolves the problem.

very informative video.

i’ve been looking screencast in validating forms both client and server side
and found it in this video.

learned a lot!

Thanks Jeff!

Jeff thanks for the if(is_ajax){} trick, it was really useful

Nice screencast Jeffrey, but I’ve a question, why don’t you use $(’#addComment form’).submit(), instead of $(’#submit’).click() ?

Well NAH, what if you press enter to submit, #submit HASNT BEEN CLICKED. its COMMON SENSE to submit a form WHEN IT HAS BEEN SUBMITTED and not button click ……….

Amazing tutorial, thanks Jeffrey!
Good video, the code is easy readable on the full screen.

In the file leaveComment.php (downloaded) you miss the else statement on line 24 – else { header(’location….. } so it displays twice the page…

Isn’t it a good idea to begin the javascript using $(document).ready() ?

Another very cool tutorial as always!

You may mumble your words as much as you like …
this screencast is great!

ThanX
Kind regards
Rata

One small thing,

Creating an animation after someone clicks the submit button isnt exactly helping the user with the “how long does this take” feedback.

Although I think what you have there is really cool, I dont think its applicable in real world applications.

For example, what if the server hangs and what you have there is the only thing users see. Those users could and might navigate off teh page without the post effecting the DB.

Wouldn’t it be more practical to add this animation to actual loading sequence?

Again, nothing wrong with this option… it looks great, but…. you know…

Great screen cast, I loved it…

P.S – One of your very old ASP.NET screen casts has it where you create a that shows exactly what I’m trying to say… That being more practical and sending the correct feedback to the user.

thank for code

Thanks Jeff for this nice tutorial.

Please resume the CodeIgniter tutorials. Could you please use AJAX in your next CI tutorial.

Thanks again.

If you get an error like this:

Notice: Undefined index: comment in C:\wamp\www\comments\index.php on line 127 – 129

Which is this line(s):
<input type="text" id="name" name="name" value="” />
<input type="text" id="email" name="email" value="” />

(sorry for the code is messed out)

Just use this fix: (Line 127)

<input type="text" id="name" name="name" value="” />

And this one: (line 128)

<input type="text" id="email" name="email" value="” />

Finally: (Line 129)

Enjoy!

Thanks for this great tutorial. I’ve always wondered how to do this and find it very impressive whenever I encounter it on web sites. This is a great thing to have in one’s skill set as a web designer/developer. I love how it combines so many different technologies. Very cutting edge. Thanks again.

When I try this on my own local testing computer I get this kind of thing displayed in the form fields when the page loads:

Notice: Undefined index: comment in C:\htdocs\Tutorials\ajaxComment\index.php on line 129

If I fill out the fields anyway the info is inserted in the DB but the ajax reloading of the page hangs up and things get wacky. If I refresh the page, my post is displayed.

Any thoughts or solutions would be appreciated.

Wow. Great!!!

This was VERY helpful. Many thanks!

I love that aJax, plus when you add animated gifs. Way to get my blood flowing.

Very nice tutorial! Keep it up!

Another great tutorial. Thanks, Jeffrey!

Hey very nice Tut! It will be very helpfull for me

Wow! This is got to be the longest tutorial/screencast I’ve seen you do. Out of curiosity, is it? if not, which one?

Thanks again Jeff, you covered a lot!

Nice one Jeff, picked up a few gems in there.

Like the php javascript test, didn’t know about that one, but it tied in beautifully with this project.

You are insanely good at this!!!

I hope to have you skills one day. I have been watching a lot of tutorials on PHP etc but I don’t seem to be soaking it up very quickly!!!
It’s frustrating!

I will keep watching your videos though and hope it clicks one day!

Thanks Jeff

Noob question alert:

How would I go about reversing the order, whereby the newest loads on top?

Thanks! Had absolutely no trouble understanding you. explained everything so well.

This is a great tutorial, thanks for sharing. I’m however getting an error when trying to post a comment. It reads “Column ‘name’ cannot be null”. I’m passing the first parameter into the prepare as NULL and the next three as ‘?’. Anyone have similar issue

learn a lot.
