I usually set up what amounts to a quick controller page. The page
accepts a GET variable that identifies the download, and it also
delegates to a helper object that determines the access level.
If the delegate determines that the person should be able to download/
view the content, the controller sets the headers, retrieves the file,
and then outputs the file contents to the output stream.
Otherwise, the controller redirects the visitor to a page that let's
them know they don't have access, but prompts them to pay/sign up to
get the access for the product.

Hi Folks,
This may not be strictly a PHP question but there may be something
in PHP to do what I want. I am in the process of putting together a
pretty basic website using MySql and PHP on a third party host. One
of the function is to allow known stockist download a catalogue
(.pdf). I am fine to do login etc. but I am not sure how to
approach restricting the catalogue. I can do it so that the link is
only visible if the user logins in, but that doesn't stop the link
being downloadable even if it is not visible. I was thinking I
could put it in a location not visible to the public and transfer it
to a location that is when the user logs in, something with a
cryptic name etc... but that doesn't really sit right with me and
at very least gives me some house keeping issues....
Anybody got a suggestion as to the best way to handle this ?
TIA,
JC

-- I usually place the documents in a folder above the web root so that it
can not be acccessed directly through a url, then as Adam suggested, create
a controller that will validate the user, read in the file and send it out
to the user.

I'm using the pear class Mail_RFC822::parseAddressList() which
apparently only throws an error_object for PEAR_Error.
You might want to consider the filter_var() function if you can - it
will be much faster.
The manual says that PEAR_Error is deprecated, so I'd like to use
PEAR_Exception; but; am having trouble getting it to recognize the error.
Can anyone help me with this?
You could use your own version of RFC822.php and use the wonderful
search and replace. Don't worry about updates, Mail_RFC822 is quite
stable, and has been for some years.

filter_var() is an excellent suggestion and works great.

Man... this is really irritating the heck out of me. I have recently been
learning regular expressions, and thought I was "fresh" enough to fix this with
new eyes. However, I've been running into all kinds of trouble, and I now
impatiently anticipate an expert's answer, much the same as you. :)
It's interesting to me that ``$st = preg_replace("(SUN)", "FRIKI", $st);``
replaces the word "SUN" with the word "FRIKI", but ``$st =
preg_replace("(^SUN)", "FRIKI", $st);`` does the same thing (when it should be
replacing everything BUT the word "SUN").
Annoying behavior. Is this particular to PHP's regular expression engine? I
should try this in VB.NET and see what the results are, as that's what I'm used
to playing with (for the time being).

Hi All,
I must be overlooking something here ...
$var1 = "01011090"; $var2 = "010190"; // 2 strings
if ($var1 < $var2) ECHO "var1 < var2"; else ECHO "var1 >= var2"; echo "<br />";
$r = strcmp ( $var1 , $var2 );
if ($r < 0) ECHO "var1 < var2", "<br />";
2nd line says: $var1 >= $var2

Implicit type conversion. "<" is a numeric operator, so your strings
are silently promoted to integers, where (1011090 > 10190).
strcmp() treats the strings as strings, and orders them in something
close to ASCII order (which isn't the same as alphabetical ordering,
BTW, and see the comments at www.php.net/strcmp for locale-specific
gotchas).
PHP's implicit conversions can bite you if you don't understand them.
Try this one:
$a = 'string';
$b = 0;
if ($a==true && $b==false && $a==$b)
{
echo ('universe broken');
}

Hi David,
I already suspected that the > operator forced a numeric comparison.
Even if I use: if ((string) $var1 < (string) $var2) ...
So I have to use strcmp()

But, that's what the 301 does... it's say it's over there. Your browser
is what actually takes you over there. And I know in Opera you can
disable automatic redirects so that you actually have to say... hey I
wanna go where I was told to go.

*lol* I didn't use Google because they are obviously correct, my primary
reason for using Google was because they chose to redirect despite that
high probably they would have concerns about performance.
I'll let this die here. I know it wasn't really resolved the last time
either. My hackles just go up when someone argues performance as a
reason to present information in the wrong location :) For instance,
let's have Google start an index for the following page:

Hi,
Apologies for posting this here but coudn't find a decent Smarty list.
I've been using Smarty for 4 years without much problem. I'm adding some
extra functionality to a page used by 2 members of staff. My snippets of
relevant code are:
$smarty->assign('clearance', $clearbits['clearance_alt']);
<td align="right" class="s9">Clearance {$clearance}</td>
<td class="s9"> </td>
<td bgcolor="aliceblue"><select class="formInputText" id="clearance_alt"
name="clearance_alt">
<option value=0{if $clearance==0} selected{/if}>Select</option>
<option value=1{if $clearance==1} selected{/if}>Yes</option>
<option value=2{if $clearance==2} selected{/if}>No</option>
<option value=3{if $clearance==3} selected{/if}>Failed</option>
</select></td>
You will see that I have called the variable in the first column. On the web
page, this displays as "Clearance 1". I would then expect 'Yes' to appear
selected in the column three drop-down box. Unfortunately, this displays as
'Select'.
I have tried deleting all the cached template files as well as single and
double quotes around the 0,1,2,3 values, all to no avail.
All the other Smarty stuff seems to be working on the site.
Can anyone point me in the right direction?
Cheers

try doing this..
{if $clearance eq 0}
instead use ==
i saw that some version of smarty has a bug related to this issue
BTW .. you could use the options helper [1]

Hi George,
I tried your code and it works.
If you have some way of remote assistance I can have a look "on-site",
if you like.
But it could be that you just need a good sleep, and then look again ;)

Right... I forgot to ask which Smarty version you have. I tried it with
the last.

Iv,
Thanks, but its Firefox to blame. Apparently it holds previously stored values
in form fields. These are released when the user holds shift while reloading.
Cheers

In which situation would somebody use a static method, instead of a
function in a namespace, after the namespaces arrive with 5.3?

If the functionality doesn't conceptually promote the inclusion of the
variables it works on (i.e., no class variables), doesn't conceptually fit a
scheme where instances can exist, and likely won't benefit from refactoring
into component methods, then I could see using a namespaced function.
Most of the time, though, I'd probably start out with a class method instead
of a namespaced function so I could more readily adapt to OOP practices if
desired as the implementation evolves.

Here I would do the same.

Hm...
Would you consider it safer to convert a static method into an instance
method, than implementing a namespaced function into a (new) class and
redirecting the calls?
I am not starting a fight, I am really interested in what you think.

Hi all,
I've put this off as long as possible, however I think I've reached an
impasse.
I've got an application that I've been writing. One of the modules for
this app is an event calendar. I've got the calendar to the place where
it displays the current month as well as previous and future months. The
place I'm stuck is it will only show months in the past or the future
that are months in the current year.
Basically the method I'm using to move backward and forward is with Unix
timestamps.
1. When the calendar first loads the "what" is checked for;
// passed in via $_GET
$what == current, prev, or next
a. "current" is the default
$now = time()
$prev = date('n',$now)-1
$next = date('n',$now)+1
b. Timestamp values are then stored in an array and then
sent to client in session cookie which is then accessed
upon each subsequent request to display the event calendar.
My question/boggle is why, when the calendar advances to
December(current year) it will display January, but of the current year.
The same happens in reverse.
Once I reach the end of the year either in the past or future the month
increases or decreases accordingly, but the year doesn't change. Since
the year value isn't changing the month calendar days that are displayed
simply repeat themselves.
I know there's something I'm missing, but I am definitely not seeing
what it is...
/********************** code below ************************/
$cal = new Calendar;
$calpos = array();
// check incoming values
if ($what === "current"){
$cal->setCal(0,0,0,date('n'),1);
$now = time();
$prev = $cal->getStamp(date('n',$now)-1,1);
$next = $cal->getStamp(date('n',$now)+1,1);
$calpos['curr'] = $now;
$calpos['prev'] = $prev;
$calpos['next'] = $next;
$_SESSION['calendar'] = $calpos;
}
elseif($what === "prev"){
$peek = $_SESSION['calendar'];
$now = $peek['prev'];
$cal->setCal(0,0,0,date('n',$now),1);
$prev = $cal->getStamp(date('n',$now)-1,1);
$next = $cal->getStamp(date('n',$now)+1,1);
$calpos['curr'] = $now;
$calpos['prev'] = $prev;
$calpos['next'] = $next;
$_SESSION['calendar'] = $calpos;
}
elseif($what === "next"){
$peek = $_SESSION['calendar'];
$now = $peek['next'];
$cal->setCal(0,0,0,date('n',$now),1);
$prev = $cal->getStamp(date('n',$now)-1,1);
$next = $cal->getStamp(date('n',$now)+1,1);
$calpos['curr'] = $now;
$calpos['prev'] = $prev;
$calpos['next'] = $next;
$_SESSION['calendar'] = $calpos;
}
<================================================================>
function setCal($h=0,$m=0,$s=0,$offset,$dayVal=1){
$stamp = date('U',mktime($h,$m,$s, $offset,$dayVal,date('Y')));
// Using the stamp the various necessary properties are set for the
// object
function getStamp($dateStr,$dayVal=1){
return date('U',mktime(0,0,0, $dateStr,$dayVal,date('Y')));
}
