That depends on how you want to display it (and if you just want to display
it, why aren't you rendering HTML with the PHP in the first place?).

header( 'Location: http://www.somewhere.com/the/page/to/load.php' );

The parameter to the Location header should be a full URL, although many
browsers tolerate relative.

Well, off the top of my head, you could have your "next script" do some
checking (if/switch statement) and then use a header-redirect that
would be based-upon one of the four user choices?

[PAGE 01] ---> [NEXT SCRIPT] (what did user choose? Using $_REQUEST)
---> header refresh ---> ([URL 01] || [URL 02] || [URL 03] || .... )
---> [URL --]

Just point your form to the script that does the checking, and then use:

header("Refresh: 0; URL=http://www.yourDomain.com/index.php?page=$var");

Does that make sense?

Of course, how you do the refresh all depends on how your site is
setup...

I am sure there are better ways though... :)

I have found that using the header function doesn't actually redirect the
page, it pulls the content into the page that the function is called from
(which works good for somethings, but can get confusing with post variables
and such). Its been my experience that meta tags work better.

I'm not sure I understand what you mean. if the header function is used
then the redirect will occur before any content is sent to the browser.
if used properly then an exit(); will follow the header statement.
Additionally the OP said that all of the data was passed to the session,
so it will exist when the visitor gets to the target.

Maybe you meant something entirely different though :)

I guess what you are saying is that this:

Is better than this:

header("Refresh: 0; URL=https://www.theNewUrl/forward.html");

attached mail follows:

My experience was with the Location keyword, it might work better with the
Redirect keyword in the header function. I stopped using header and Location
after a few problems and <meta> has never failed for me. MHO.

I didn't know you could do that *lol*. Either way, I think the example I
gave is better. Why stop at an intermediate page? The location header is
immediate.

What kind of problems did you have? I've never experience a problem with
the location header, but would be interested to know of any gotchas that
I've just been fortunate enough to miss over the years.

attached mail follows:

hello again,
I tried the meta tag stuff and well where i had it it didn't redirect or
refresh, it just litterally echo'd the meta stuff so maybe i read the
manual page wrong but it either does that, or presents me with a blank
page and i know the pages i have it go to aren't blank :p so i guess i'm
doing the meta tag slightly wrong or not in the right place but i guess
actually if the form passed the variable i could go ahead and just
substitute the "url=http://whatever.com/page/to/load.php".etc, to having
the url equal to the variable being passed..yes i'm a moron at times :p
and its not my usual time to be up but maybe that has something to do with
it anyway i will do some reading when my mind is switched on lol

I do not think that using meta is better than header but header has one
problem ( but in my view it is feature) normally.
for eaxample:

<?php
session_start();

$_SESSION['somevar']="anything";
header("location:url");
?>

In this script session variable will not be set and will not available on
other
pages, because sessions also works with headers and headers executed (sent)
in
reverse order.
Am I correct?

Aaron, you was having problems with sessions na ?

Shouldn't be a problem if you change it to:

<?php
session_start();

$_SESSION['somevar']="anything";
session_write_close();

header("location:url");

I generally wrap redirection in a function, that way any shutdown
routines can be performed transparently -- and also the URL can be
reworked from relative to absolute.

Yes indeed, but normally people do not know about this.
Alternatively we can reverse the script, I mean, we can write the header
line as first line of script.

Maybe so, but if you don't know to plug the power saw in, you're not
going to get much sawing done either.

I agree. I was just informing the group about the problem Aaron may have
with header function.

Since we are talking CSS and Tables one of the first things I do when
I come across a site that is blatantly using CSS is to resize the
text. I find that in about 80% of the cases the pages are not
designed to handle resizing the text, which is a big pain.

This is why I tend to stay with tables in a lot of my deisgn. I have
done a few CSS things here and there but it takes too long to do it
properly. That is one thing I notice is convieniently left out of the
tutorials. If they don't know about ctl+ why would I waste time
reading their tutorial? When I come across a tutorial on replacing
tables with CSS I look to see if it mentions the user resizing the
text. If I cannot find that I close the tab.

What is the surefire way to have divs and spans that will resize along
with the text?

font size in CSS is a big problem, but not really its fault. Just
another problem dealing with various browsers and the PC/Mac thing.
I use styleswitcher to allow for resizing. It changes style sheets,
so other stuff can grow with the fonts.

The time consuming part of CSS is also about cross browser as well.
If I just had to do a site for my mac, it would be a breeze. But I'd
heard other browsers are used.

I still prefer pure CSS lay-outs though. I think in the long run,
they save time, and they just look so damn pretty as it keeps code so
clean.

Hi!

I've been playing around a bit with the XML parser in PHP, but I couldn't figure out, how to get it object oriented.

I would like to do something like this:

class MyParser {

private function xml_start_element(...) {
}

private function xml-stop_element(...) {
}

public function parse() {
[start stuff]
xml_set_element_handler($parser, "xml_start_element", "xml_stop_element"); //can't find function
[end stuff]
}

}

This ends up in an error, which says it can't find the function "xml_start_element()" since it doesn't take the member fuction as an argument. I've tried some stuff like setting "$this->start" as callback, but it didn't work either.

Has anyone of you a solution to this problem? I just can't find any myself.

thanks,
Norbert

use array notation for object method handlers:

xml_set_element_handler
(
    $parser,
    array( $this, 'xml_start_element' ),
    array( $this, 'xml_stop_element' )

I apologize because I posted this question earlier under Re: [PHP] href
difference between OS's, and am still struggling with the problem. I
think I have fished all the way around the lake, with no results.

I cannot get href links to local files to work on an XP machine. The
exact script that is creating the links works perfectly on two W2K
machines. On the XP machine if I right click and select print, the given
file will load in the application as desired, but a print dialog box is
also opened. If I right click and select open nothing happens, same as
if I just left click the link. I have added an AddType in the Apache
conf file, but no change. I have looked at the IE security settings,
nothing. The file mime type is set because I can use the file explorer
and clicking on a desired file and the application will run and load the
file for editing.

I'm writing a content management application which saves file paths
in a database and allows users to search the database for those
files. Problem I'm having is that although the PHP script that
handles the database queries works fine, when the search results get
to the browser, all the paths are off limits.

I can't just move the photos inside the web folder as we're talking
tens of thousands of images that are already organized into a folder
structure that must be maintained as is.

Is there a way to allow the web page to see these photos?

The images are stored on a Windows box and all the web server stuff
is on a G5 Macintosh running OS 10.4 3 (in case that has any bearing
on the matter).

Thanks for any help
