Refreshing part of a page

[PSN]

Hi all,
Can some one help me if it is possible to refresh a part of a page,
without reloading the whole page. Let's say, i want to add a small
message box to my webpage. After writing a message, the user presses
the send button and i want only this part of the page to refresh and
give him a status message saying his message was successfully received.
If yes, how can i do it ??

thanks.

Hi,

This can be done relatively easy with JavaScript.
PHP only produces output for a browser and is thus not involved in
displaying parts of a page.
The technics you could use are:
1) An IFrame
or
2) AJAX

Have a look here for a quickstart:
www.w3schools.com and look at AJAX.

Regards,
Erwin Moller

PS: Since this is not a PHP related question, I suggest you continue in
comp.lang.javascript, an excellent group with fast responses.

I used a <iframefor the script shown below .

From the sound of it you wont be setting the page to refresh every 15
seconds or whatever - so - you wont get the flicker effect .

Don't think I'd recommend W3Schools, Erwin, especially if their HTML
tutorial is anything to go by. Much time and effort is spent in Web
authoring newsgroups debunking the myths and false impressions
propagated by the W3Schools' HTML tutorial. For example, in spite of
what they say in later pages, the introduction fosters the common
misconception that tags are instructions to browsers how to display Web
pages.

I am of course making the assumption that the other tutorials are
similarly poor in quality. Criticism of their PHP tutorial would be
appreciated.

Don't make assumptions unless you've checked them out.

I recommend several of the w3schools courses. And I use them regularly
for references myself.

I am standing up for their PHP course - which is on topic of this
newsgroup. Another poster disparaged this course without even looking
at it, based on what he's heard about their HTML course.

Hi John,

You may be right, I never looked at the HTML course.
All courses on w3schools I did look at gave me a good impression.
Of course w3schools is not a place to master a technic, but it is a great
place to get a quick overview so you know at least what is involved in a
certain technic.
Darn, I heard so much about AJAX some time ago it made me nervous. SO I
checked their guide, and I knew within the hour what it all was about, and
also recognized the technic because I used it years ago, only without the
handy HTTPXML-object thingy or whatever name it gets in different browsers.

For an expert it is easy to spot cutted corners by w3schools, and surely
you'll find things that are not 100% correct.
The advantage is that they provide a quick overview without the details. In
most cases you don't care about the details when just starting with some
technic.
And above all: I am too lazy to keep up an online trainingcenter, so I have
no right to complain. :-)

Personally I REALLY LIKE quickstart guides as presented by w3schools.
I really don't like megabytes/hundreds pages of technical stuff before
getting something done.
I like to see a technic at work, try it out myself, and if the technic and I
are compatable, I dive into the Gory Details. :-)

But of course, this is just a matter of taste. I think different people
learn in different ways. I am just the 'hands-on' type of guy, so I advise
w3schools a lot.

just my 2 cent in defense of w3schools. :-)

Erwin Moller

[re W3Schools' PHP tutorial]

Another poster disparaged this course without even looking at it,

Talking about me? Either (a) you've spectacularly misconstrued my
remarks, in which case I can only point out that what I was talking
about was not specifically their PHP tutorial - I haven't even read it,
ferchrissakes! - but W3Schools in general; or (b) you've made egregious
logical leaps and bounds, without so much as the shame to cover them
up, to arrive at the conclusion that I "disparaged" their PHP tutorial.

Put words in my mouth if you like, Jerry, but the thread is there for
all to read. Where I said that I wouldn't recommend W3Schools, I also
qualified my statement with 'especially if their HTML tutorial is
anything to go by'. In other words, if the quality of their HTML
tutorial is representative of their other tutorials - and this
condition I made explicit - there are probably more technically
accurate and less misleading Websites to recommend. Besides, to drag
this thread kicking and screaming on-topic, I _encouraged_ discussion
of their PHP tutorial.

based on what he's heard about their HTML course.

Me again? More what I've read than what I've heard. Their HTML
tutorial is shamateurish.

Yes, John, I'm talking about you. The discussion was about PHP
tutorials, and Erwin the courses at w3schools.

And you had to hop in there and comment about how you would not
recommend w3schools - based on your experience with a single course.
And you don't offer any alternatives.

And if you have a problem with one Microsoft product, do you claim ALL
products from Microsoft are bad? Or if you use one thing from
HotScripts, SourceForge or whatever, do you claim everything they have
is terrible?

Yes, if that is the quality of tutorial churned out by W3Schools.

And you don't offer any alternatives.

Does my criticism not stand whether or not I offer any alternatives?

And if you have a problem with one Microsoft product, do you claim ALL

Of course not, but after two, three or more problematic products, you
might begin to question the company as a whole.

Or if you use one thing from HotScripts, SourceForge or whatever, do you
claim everything they have is terrible?

HotScripts and SourceForge are fundamentally different to W3Schools,
or at least the image W3Schools projects, in so far as HotScripts and
SourceForge host packages and products created by communities of
developers, whereas W3Schools is three authors making money from
writing tutorials.

If you're going to criticize, you should offer alternatives. Otherwise

Not really. The w3schools courses are not all created by one person,
either. And I don't see where they are making any money off of the
site. Look at their header:

"W3 Schools - The best things in life are free".

Or are you talking about the AdSense ads? I doubt they're making much
off of those, either.

http://www.w3schools.com/about/about_refsnes.asp

http://hotscripts.com/about/index.html
http://sourceforge.net/docs/about

Sure, it's run by a consulting company. But I highly doubt they make
their living off of their website. They probably pay for their hosting
with AdSense - but not a whole lot more.

Yes, sometimes things heat up on usenet for no appearent reason (for the
outsider). Different cultures, different people, different way to express
opinions, and they all come together here on usenet.
I try to think that people care a lot and get excited because of their drive
for the matter. (to give the matter a positive twist.)
About Jerry: he is very precise (which is good for a programmer) and says
straight what he thinks, that sometimes irritates people, but he knows his
business. I had some flaming going on with Jerry too in the past, but I
won't let that happen again. :-)
Waste of energy to flame each other IMHO, but if both sides want to make
some point, there is little to stop them of course.
Except to deal a cool beer around (or a tea) when things heat up. ;-)
It is only about zeros and ones in the end. :P

Best of luck!

Erwin Moller

Here's what I meant. If W3Schools - that group of three Norwegian

You then read far too much between the lines and decided that in saying

Not if the criticism is based on the contents of a completely different
course. Now if they were asking about PHP courses and you responded
with criticism specific to the PHP course, that would be appropriate.

What you said is like me saying "Don't believe everything John Posts.
He has some bad responses in the xxx newsgroup" - where xxx is
completely unrelated to PHP.
