All you need to do is to include an hidden field in the form. Then check
the respective $_POST or $_GET variable is set. If it is not set, show
the form for the first time. If it is set, validate the form and process
it. If the form is not valid, show the form again with previously
submitted values.
This tutorial video explains this workflow:
http://www.phpclasses.org/browse/video/1/package/1/section/usage.html
This example script demonstrates how to setup your code. It uses a
function of a forms class name WasSubmiteed() to check if the form is
being presented for the first time or is being submitted:

I try to avoid the use of hidden form elements as much as possible,
especially for tracking whether a user has submitted a form or not...
I use name="submit" for the submit button instead, that will pass the
value of the submit button to the action script.
above all i use a template engine, smarty to take care of the
presentation for me(like deciding whether to show the form and/or a
success/failure message)

That only works if the user clicks on that submit button. If the user
hits the enter key in a text input, the form is submitted but the submit
input variable is not set. That is why an hidden input is a safer solution.

i doubt that, because i use the above mentioned method in nearly all
of my projects, and all of them are working fine.
P.S: i prefer keyboard to mouse as a input device

and yes i forgot to mention... i avoid hidden form elements because

You say you don't use hidden fields because they can be modified too
easily, yet you say you check for the submit button? Which out of the
two do you do, as last time I checked, modifying one form field is as
easy as changing any other!
Also worth noting, you can only successfully check for the name="submit"
value if there is only one submit button in your form, as that is then
the default (and only) submit that the form can use, so it uses that. If
you have more than one submit button (and this includes image input
elements) then using the keyboard will use the first submit field it
finds I believe.

I completely agree with you. changing submit text is as easy as
changing hidden fields, but its less likely for a user to modify a
submit button as compared to a hidden field. moreover it just reduces
my typing load. (This is just my practice)

Cant agree with you on this though. as far as i know using name=""
(names of the two buttons may/may not be unique) is the only way to
track form submission for forms with multiple submit buttons. Please
point out if you think otherwise

before the excel import, some date fields look like "2009-9-29

Use the tool that PHP provides for such problems.

try using strtotime() on that field and see if it works.
http://php.net/strtotime
I'm pretty sure that function will handle it.

I don't know about the javascript, but if the CSS is an external file,
then it wouldn't get dragged along with the original file, and thus
wouldn't be there to style anything on the HTML page. Just a guess.

thanks
using a basic curl call
$curl_handle=curl_init();
curl_setopt($curl_handle,CURLOPT_URL,'http://example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER,0); // return into a variable
curl_exec($curl_handle);
Along the lines of what Paul has already alluded to, you will probably find upon further examination
of the html source that the "linked" files (js, css, etc...) are probably using relative paths, not
absolute paths including the domain name.
To fix this, you would have to do a little source code rewriting to add the full domain name and
directory path information to the "linked" in url structure.
I know if you do this with wget (cli app) that you can have it re-write the domain + path url
references. But, I'm not sure if cURL has an option for that. You might RTM on the cURL options
page to find out.

using the <base tag is a solution to your problem if the links are relative..
http://www.w3schools.com/TAGS/tag_base.asp
but I am not sure if base tag works outside <html></html>....
try... <base href="URL"></base> before curl_init()
where URL is parsed using PHP's parse_url() function on http://example.com
in either case if there are any external js/css files cURL wont fetch
external files(and if they are internal/inline your browser should
display them already).. your browser will have to fetch them for you,
net console of firebug will be helpful in that case.

Some browser security settings may not allow you to run Javascript code
that exists on another server though. The <base> tag can be used to
reference the external CSS and Javascript, but watch out for security
settings on client agents.

not many users use those kind of browsers, because if they do most of
the websites which use CDNs will not work.
Firstly, it is not a good idea to fetch an entire web page and snow it
to an user. (use iframes if this is a must)
Secondly, this idea may not be feasible if the web page in question
uses AJAX, because none of the browsers allow cross domain AJAX
requests
As a side note, use str_replace("<head>", "<head><base....></base>",
$text) if base tag doesnot work

I've read that the upcoming Firefox 4 may have some features built in
for this sort of thing, and there are plugins out there for most
browsers that can do this as an added layer of security.
On this front though, has anyone else read about Microsofts Gazelle
browser/os? I'm not trying to plug it here or anything (I'm an anti
Windows person myself!) but the concept looks interesting. It goes
further than Chrome where each tab has it's own process by giving each
domain specific object its own process/sandbox.

Sorry but I could not understand what you meant by "this"
coming back to original problem... you should keep in mind that if
base tag is used, the links (<a href="...">) in that page will become
absolute links instead of relative links

Hello
I noticed a problem using iconv, but investigation showed, that this is
not exectly the iconv itself, but something like php encoding.
From the beginning:
a hava an incoming variable $text;
it has some Polish diactics 'strona główna'.
I expect to remove diactics : 'strona glowna'.
So I use iconv: iconv('utf-8', 'us-ascii//TRANSLIT', $text)
and unfortunetly i get: 'strona g??wna' ... But only under apache, in
browser
The same file, command, etc run from bash gives: 'strona glowna' ... OK
So i think : "bad config", but double checked and configs are
identical... (cli and apache2)
Best part: for 2 or 3 times after starting computer (debian), it didn't
worker until I did: (apache start && apache stop - not apache restart),
then it worked. Now it doesn't work any more. No other config (except
php was changed).
Any ideas?

I would recommend using an open framework like yui/dojo/jquery for ALL
your javascript needs..(i personally prefer jquery) each of the above
mentioned frameworks have wysiwyg editors of their own.
try using http://code.google.com/p/jwysiwyg/ i doubt it will conflict
with your javascript with compatibility mode ON
http://docs.jquery.com/Using_jQuery_with_Other_Libraries
TinyMCE as such is a very good plugin (i use that in nearly all of my
projects and never faced a problem with it). may be you should try to
debug your code that is conflicting with tinyMCE
