What I want to do next is to change the menu from being hard coded on all of
my pages to being an include making the menu more manageable. The stumbling
block is I want to be able to keep the CSS functionality where you have the
active indicator which has different CSS for the link of the page you are
on. I have seen this done with PHP before with something like IF on active
page use this style ELSE use this style. Can any PHP gurus assist me in
coding something like this?
I don't believe it is too difficult, but beyond by scope right at the
moment.
It's not a php solution, but you can change it to one easy enough.
This will give you the idea.

I did something similar on my page. I did a simple comparison in a
loop through the menu DOM,
foreach ($nodeList as $node){
if ($currentPage eq $nodeHref) { //set class attribute = 'active'; }
}

Thank you for your response, Tedd.

the archives.
I'm reasonably certain I saw the thread but it was no help. I will go back
and review it in case I missed something.

Well, there's the meat of it, isn't it? I wonder how Paint Shop Pro comes
up
with PPI (Image - Image information). I have several thousand scanned
images
with resolution ranging from 72 PPI up to 1200 PPI (As reported by Paint
Shop
Pro) and want to discard, or more likely tag as rejected, any that suffer a
resolution of less than 150 PPI. As you might imagine, I find the thought
of
doing it manually with Paint Shop Pro repugnant.
T> For example, if you take an image that is 1000 x 1000 pixels and wish
to view it at 72 dpi, then the image size will be 13.8 x 13.8 inches.
If you want to view it at 300 dpi, then the image size will be 3.33
by 3.33 inches in size.
Understand?
I think so, but I am a bit dense. I'm not concerned with image size but
rather
native resolution. Thanks again for taking the time.

Yes, but that's a different question.
On one hand, you have an image that can be presented in numerous resolutions.
On the other hand, how was the image first obtained?
Some images contain that information, but it's defined by the device
that captured the image, for example:
http://www.exif.org/samples.html
In that data set is a host of other information, such as
shutter-speed, flash, focal-length, camera make, model, and such.
Check out:
http://www.digicamhelp.com/what-is-exif/
If you want to access these data via php, check out:
http://us3.php.net/exif
But understand, not all images contain that information.

Thanks again, Tedd.
I've checked out the links but still no luck. As I stated (Or implied.)
in my first post, I have played with exif_read_data() but it is of little
use with the scanned images I've examined. You can see results of my
experiments with exif_read_data() and getimagesize() at:
http://www.campden-main.com/~orchids/test/test_exif.php
You'll note that if I simply divide the dimensions in pixels by the
dimensions in inches, I'll get the resolution in PPI. Perhaps the solution
to my problem lies in simply finding a way to obtain the dimensions in
inches
(As either exif_read_data() or getimagesize() will give me the dimensions in
pixels.) and just do the math.
Again, thanks for your help!

PPI or pixels per inch is a printing term. It has nothing to do with
viewing on a monitor as a monitor's pixel setting is your set
resolution, as in 800x600, 1024x768, 1600x1200.. etc. This is a
constantly debated urban legend. A pixel on a monitor is a pixel...
Pixels per inch are used in the printing world and relates to how many
pixels are used to provide one inch of printed space. Obviously, at
least up to the limits of the printer being used, a high PPI setting
produces a higher quality 'printed' image.
If you don't believe me, use your paint program, change the PPI of an
image and notice how the image doesn't change size on the screen. Also,
do this and switch the image size display back and forth between inches
and pixels.. the pixel count doesn't change, only the inches change..
but again... that's the printing world and has nothing to do with
display on a monitor or webbrowser.
So, an image 10,000pixels by 10,000pixels will be huge on screen. If set
to a resolution of 1000ppi, the image would be printed at 10" x 10", but
you still can't view the whole image on a monitor without zooming out.
If resolution we set to 10,000dpi, the image would print as 1" x 1", but
you still wouldn't be able to view it on a monitor (unless you have an
awesome multi-display setup that can reach 10,000 pixels wide and tall).
That's the bottom line.
So, I keep seeing 'display size' when I'm thinking the term should be
'printed size'.

But there is SOME kind of data embedded in some images providing the
resolution at which they will/should be printed...
Because *SOMETIMES* http://php.net/getimagesize provides a reasonable
"resolution" in its result array.
'Course, sometimes it's full of crap, too...
Thing is, if you go changing those settings, and then save and then
print the two versions, you'll get quite different printer output.
So OBVIOUSLY the files are different, in some way that printers
understand, even if PHP only half-understands it.
'Twould be nice if PHP was as smart as a printer :-) :-) :-)
YMMV

Untrue. GIF images *are* supported by the GD library. They were

years ago). It is being actively developed, and expanded. They've even
added support for animated GIF's.

Yea; but it does work very well. For example, you can resize a GIF in PSP and get a reasonable size file with good
quality.

PHP5 is installed as CGI, not Apache module.
Does anyone have any experience with Nexcess.net -- advertisers on back

At hub.org you can install anything - virtual server.

Anthony,
I really don't know, because computers are much faster, so there may not be
the time lags there were 10 years ago.
As I understand CGI, the web server sees that the page is of type .php,
starts up PHP, PHP processes the page, the web server shuts down PHP and
sends out the results. The overhead of starting and stopping PHP (or Perl,
etc.) was the complaint.
When PHP is loaded as an Apache module there is not startup / shutdown
overhead.
If I have this wrong, or if PHP5 as a CGI stays resident and there is no
penalty, will someone please correct me.
Regards - Miles

No, nothing wrong there, I think.
But there are other differences. (Like some functions not
working, etc.) Pros and cons, one might say. Anyway, here
are some results of a quick google search:

Hmm.. I just couldn't find it but there should be a page
about it on www.php.net ... (^_-)

Hi,
I created a small bannering program. It works great in Firefox. But I have a
problem with IE.
If I place the banner on a different domain than the bannering program, Ex:
www.bannerserver.com
www.otherserver.com has img tag calling from www.bannerserver.com
I use a session to keep track of the banner that is displayed, have even tried
using cookies directly.
Works great in firefox, problem with IE is first time vising
www.otherserver.com, clicking on the img does not work, apparently, the session
was never start/recorded when retrieving the image. However, if I go back to
www.otherserver.com, it then works fine, I can go anywhere, as long as I don't
close the browser, www.otherserver.com works.
Why would IE not be recording the session info on the first visit? Firefox does
it just fine.
Anyone run into this?
Thanks for any help.

as long as I don't close the browser, www.otherserver.com works.
Why would IE not be recording the session info on the first visit?
Firefox does it just fine.
Anyone run into this?

When using session_start() to begin a session this session will remain
open until the page has finished loading or it is explicitly terminated.
You can lose the session however if the the page contains a reference to
<img src=""> with name and id references (which may be used if the image
is referencing a dynamic image, called by javascript) This seems to
casue IE6 to refresh the page session id and hence loose the session.

Hello,
Does a VxWorks port of the PHP interpreter currently exist? If no, is any
such project in the pipeline?? We'd like to run PHP scripts as CGIs in some
of our embedded devices.
Thanks for the info.

Anyone want to point me to why this isn't working:
$hr_query = "select dp_lname,dp_fname,dp_id
FROM dir_all
WHERE dp_id NOT IN (SELECT sup_id FROM dir_title2)
ORDER BY dp_lname";
There are two tables, dir_all (the main list of everyone) and
dir_title2 (supplemental). If someone is in dir_title2 then the
sup_id is the same as their dp_id. What I am trying to do is get a
list of every person in dir_all that is NOT in dir_title2. Any
thoughts as to what am doing wrong?

Kevin,
Looks like an older version of MySQL.
Check your version: subqueries were not supported until ver 4.1.
The older docs at MySQL give a work around.

One of my clients has an os commerce install which requires

It is set up to off in php.ini, as it should, but I'd like to know what
the best fashion would be for me to set it on locally for this domain

If you need to ask a new question please start a new thread - copy the
email address and hit "new" instead of replying to an existing question.
It makes it so much easier to follow.
See http://www.php.net/manual/en/ini.php#ini.list and

Basically, in apache virtualhost or .htaccess file:

Assuming you have apache as your webserver..
If you must set it, you can set it per any apache directive, like
a <VirtualHost>, <Directory> or the like or even a .htaccess (if
enabled).

One last question, considering the above code, would the following code
be a suitable replacement?
<?php
$thestyle= htmlentities($_POST['thestyle']);
setcookie ('thestyle', $set, time()+31536000, '/', '', 0);
header("Location: $HTTP_REFERER");
?>
Actually, you receive $set via GET, so you should use $_GET instead of
$_POST. A lot of people use $_REQUEST (wich is a combination of $_POST,
$_GET and $_COOKIE —check the manual), but I read somewhere that this
isn't a good practice, though I don't recall why :p
$set = $_GET['set'];
or even better would be something like
$set = ( isset($_GET['set']) ? $_GET['set'] : $default_value );
I've used htmlentities() before to filter out user's input, but I don't
know if that's sufficient to protect from all types of injections -- is it?
No, it doesn't suffice this way --it does for the script we're talking
about, but that's because you only use the data as part of the HTML
code, so no more harm can be done with it.
A tipical example would be a login script that uses the data as it
arrives, for example:
$login = $_POST['login'];
$passw = $_POST['passw'];
$sql = "SELECT * FROM user\n"
."WHERE( login = '$login' AND passw = '$passw' )";
In this case, what happens if I send something like
login: ' OR '1'='1' OR '0
passw: doesnt care
? (I avoided the ' in the passw, just in case)
Well, we'll end up with an SQL similar to this
SELECT * FROM user
WHERE( login = '' OR '1'='1' OR '0' AND passw = 'doesnt care' )
and because of the priority of the AND / OR, we would have 3 separated
conditions each enough to validate the user, as '1'='1' is true, then we
have a validated user.
Now, if I can do this, I could change the logic a little...
login: admin' AND '1'='1' OR '0
WHERE( login = 'admin' AND '1'='1' OR '0' AND passw = 'doesnt care' )
In this case you should care about ' and " (depending on which one are
you using) Again, I read somewhere that the safest way is to use
(emulated?) "prepared SQL statements", such the "?" SQL-parameters in
ADODB, PEAR-DB and others.
By the way, even causing an SQL error that is displayed to the user
(the whole message or just a part of it) can reveal info that could be
used to bypass your protection.
