Hi,
Hope I can explain this as easily as possible, basically I am using both
cookies and sessions for my script, whereby the user is allowed to choose
which method they want to login with. Problem for me is removing the
registration form, etc., from those that are logged in. The thing is the
form is in its own method in a seperate file, and its called within HTML
code so obviously if I included session_start() in the seperate include file
where the methods/classes are, etc., I'd get a headers already sent error.
So is there a solution to this?
Thanks.
---End Message---

OK I guess it's somehow like this ..
form
?php
if (isset($_POST['submit'])) {
include('sessions.php');
// include sessions.php
}
?
!-- form innerhtml --
/form
now this of course is something very bad to do and it wont work.
One way to prevent markup from being outputted is using ob_buffer() [1]
EXAMPLE:
?php
$form = FORM
form
!-- form inner xml --
/form
FORM;
ob_start();
echo $form;
$output_buffer = ob_get_contents();
ob_end_clean();
var_dump(nl2br(htmlentities($output_buffer)));
?
So what we do here is simply start the output buffer befor echoing $form.
ob_get_contents() returns the outputbuffer as it is right now.
By calling ob_end_clean() buffering is stopped and the buffer cache released.
Still keep in mind that headers will still be sent when buffering the output.
here is a more complex
EXAMPLE:
?php
ob_start(); // starting the output buffer
?
html
body
!-- inner xml --
{{replace_me}}
/body
/html
?php
$output_buffer = ob_get_contents();
ob_end_clean();
session_start();
$_SESSION['test'] = time();
echo str_replace('{{replace_me}}', 'pThis is the replaced string.br
/SESSION[test] was set to: '.$_SESSION['test'].'/p',
$output_buffer);
?
Now we start the output buffer at the beginning of the script and the
session at the end.
It does not matter whether we close the PHP tag after starting the
ob_buffer. ( like with ? )
As long as we do not flush_end or clean_end the output buffering
process it will continue caching the output (except headers).
So session_start should work after actually outputting markup.
Another method could be like we did above the str_replace() [2] ...
EXAMPLE:
?php
$some_number = time();
$html = HTML
html
body
pTime: $some_number/p
p{{replace_me}}/p
/body
/html
HTML;
echo str_replace('{{replace_me}}', 'This string was changed by PHP', $html);
?
There is still plenty of other possible solutions. Keep on rocking

Well as long as you don not provide any code it's all just wild guesses. What I tried was to show you a way of simply preventing the HTML from being sent to the browser before you include the session and/or cookie file. So you would just have to add the output buffering syntax to your existing code without changing all the scripts. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This code works fine in IE, Opera and Chrome, but gives a javascript error
in FF when I click the radio button: autostartlabel is not defined.
However if I comment out the DOCTYPE line in the header it works fine in all
browsers including FF. (Took ages to narrow it down to the DOCTYPE.) Does
anyone know why, and how to fix it?
You aren't doing it the DOM way, and telling FF3 to use HTML 4.01 (or
XHTML) means you should be doing it the DOM way. IE, Opera and Chrome
are being lax; FF isn't.
input type='radio' name='autostart' value='0'
onclick=document.getElementById('autostartlabel').className='disable';
document.getElementById('startdate').disabled=true; No
input type='radio' name='autostart' value='1'
onclick=document.getElementById('autostartlabel').className='normal';
document.getElementById('startdate').disabled=false; Yes
label id='autostartlabel'Startdate/label
input type='text' name='startdate' id='startdate' disabled='disabled'
Better would be to throw the actions into a function, e.g.
script type=text/javascript
function setStartDateDisabled(asDisabled) {
var autostartlabel = document.getElementById('autostartlabel');
if (autostartlabel)
autostartlabel.className = asDisabled ? 'disable' : 'normal';
var startdate = document.getElementById('startdate');
if (startdate)
startdate.disabled = asDisabled;
}
/script
input type='radio' name='autostart' id='autostart_0' value='0'
onclick=setStartDateDisabled(true); No
input type='radio' name='autostart' id='autostart_1' value='1'
onclick=setStartDateDisabled(false); Yes
PS: pick HTML4 or XHTML; your sample code shows the latter, the DOCTYPE
says the former.

Subject: Re: [PHP] DOCTYPE, javascript and Firefox
The pragmatic approach says that you've already fixed it: just leave
the DOCTYPE out. :-)
I'm not sure what yours should be, but based on the snippet of HTML
you posted, yours should not be HTML 4.01. Since you are closing the
input/ tags, you should probably be using one of the XHTML DOCTYPEs
(as long as the rest of your markup is consistent). I'm not sure that
would fix your issue, though.
As for why your page does that, I'm not really sure. If you leave the
DOCTYPE off the the browser will select the DOCTYPE it wants to use.
Perhaps since you declared the document to be HTML 4.01 Transitional,
Firefox is applying JavaScript rules where you can't refer to an
element in script simply using its ID attribute. You usually have to
use something like:
document.getElementById('autostartlabel').className = 'disable';

Hi Andrew and Ross, thanks a lot - using getElementById sorted it out. As
for the DOCTYPE the scripts aren't consistent enough yet to use one of the
XHTML DOCTYPEs, but it's work in progress. Maybe starting that process
caused the problem because I remember testing this successfully in FF, the
reason I persevered so long was I knew it once worked.
As a matter of interest is there a way to see what DOCTYPE the browser chose
to use? The browser is obviously smarter than I am in selecting DOCTYPEs so
maybe I should follow its cue.
Thanks to everyone else who kindly responded as well, I really appreciate
it.
Cheers

Re: [PHP] Recursive Directory Listing
Thanks, all, for pointing me to the SPL iterators. i've been hunting
around and i've managed to come up with a working script. I know it
could be better, though. I know this is terribly inefficient -- a lot
of manual repetition and no recursion. Here's what I've got,
commenting my concerns:
?php
// start from the current directory
$dirs = new DirectoryIterator('./');
//open master ul
echo 'ul';
foreach ( $dirs as $dir )
{
// only get dirs, exclude . and ..
// seems like this should be a function...
if (($dir-isDir()) AND ($dir != '.') AND ($dir != '..'))
{
// begin each qualifying dir with an li
echo 'li' . $dir;
// don't close the li, check again, one level deeper
// here's where i'm missing recursion, i think...
$subDirs = new DirectoryIterator('./' . $dir .'/');
if ($subDirs-valid())
{
// second verse, same as the first...
echo 'ul';
foreach ($subDirs as $subDir)
{
if (($subDir-isDir()) AND ($subDir !=
'.') AND ($subDir !='..'))
{
// i could manually add another
level check, i guess...?
echo 'li'. $subDir . '/li';
}
}
// close second list
echo '/ul';
}
//close first-level item
echo '/li';
}
}
//close master ul
echo '/ul';
?
this will work for me, but it's bloated, i know. and it's rendering
unnecessary ul / in the code wherever there isn't a subdirectory (i
can't get a hasChildren() check to work properly. I'd appreciate any
feedback.

I'm able to display all the contents of the correct dirs and subdirs,
but I'm struggling with my implementation. Since I'm trying to nest
unordered lists, I can't seem to 'catch' sub-directories to nest it
within their parent li tags (and then close the corresponding ul

the iterators or mine the returned arrays, is it fair to ask if this
approach is even possible?
sure, RecursiveIteratorIterator or DirectoryTreeIterator both have
a getDepth() method which might come in useful.
alternatively you could subclass either and define the beginChildren() and
endChildren() methods to output the open/close UL tags.

/collies
/some/other/dirs/
/horses
I need to display those directories in nested html lists (marked up

HTML:
ul

lidogs
ul
libeagles/li
licollies
ullisome.../li/ul
/li
/ul
/li
lihorses/li
/ul
I'm able to display one level deep (cats, dogs, horses), but not nest
the lists accordingly. Since this is for a navigation structure,
obviously I'll have anchors in the li/li lines. They'll be
formatted like so
href=index.php?section=dogschapter=colliesverse=some .
Some details about my environment:
1) no files will be in the /navigation (or sub) dirs, but i'd
(ideally) like to define a depth, to prevent 3-4 levels of
navigation.
2) I can successfully exclude dirs (. and .. and anything else I define)
3) the actual PHP script probably won't be in the /navigation
directory, so I'll need a defined starting path (ie, $root =
/site/docs/includes/navigation/ or somesuch...).
4) no database access (otherwise this whole contraption wouldn't be an
issue...)

[PHP] Change tracking
