Try using defining the style as a class instead of ID, since ID makes every child element inside the parent inheriting the style - seems that different browsers handle this differently, but my guess is that this is the case.

[PHP] menu Q
Hello,
This might not be a PHP related issue. I don't know. But this one is really
bothering me.
I have a menu on a header bar on my page. The header bar is 20px
high. The menu, code and style below, works ok on Opera but not in Ie6 or
Firefox. In these browsers the menu 'streches' the bar height so that the bg
image starts repeating itself. (looks nasty) It's almost like the menu
prints one 'invisble' or empty row beneath the menu so that the header bar
becomes about 30 or 35px high. Any ideas?
Thanks

Since web requests are stateless you need to protect yourself in some ways, this is a method to prevent those duplicate entries in the db when someone refreshes the browser and reposts the data.

Re: [PHP] Saving a BLOB image to a file (SOLVED)
So single-user disclaimer would apply?
Obviously, if you have numerous people accessing your dB and doing
inserts and updates, then all the lock-down stuff needs to be
implemented.
But, my code is not for that, but rather for someone (a single
programmer) who wants to pull an image from a BLOB and save it as a
file.
Normally, a civilian wouldn't be doing that for if they wanted to see
a file, your code would simply pull the image directly from the MySQL
to the web page. No need to save as a file.
However, after given it some thought, I would imagine that one could
get a unique generated string, create a file with that string, give
the file the correct permissions, then pull the image from the dB and
save, do image processing, and then reload the image into a web page,
and delete the file without any conflict. I can envision lot's of
users doing that simultaneously without problems. BUT, I haven't
tried it yet!

Normally, it's not needed for civilians. This is for when YOU want to
do some image stuff on your images, like to do some background
processing via your code.
As for users, they just want to see the image and you can pull that
out of your dB or files, whichever you prefer.

Re: [PHP] Clear POST variables
I am not using a session, and redirecting I think would be a bad way
of doing this because of the potential hit that the server would take
for every insert. I have done a few pages like this, and never ran
into this situation. Now I need to go back and fix this. Basically
all I have is this.
add.php
Name:
?>
Then in insert.php I have this:
if ($_POST['name'] !== "")
{
$name = $_POST['name'];
$query = "insert into Locations
(name)
values
('$name)";
mysql_query($query, $link) or die
(mysql_error());
}
This is how I learned in some book somewhere. Is everyone saying that
I need to either use sessions, or redirect so that when someone
refreshes insert.php, it doesn't submit the information again? To me
it seems that there has to be a more efficient way. I don't
understand the token thing that some are suggesting.

You can't clear out the POST variables -- they are SENT by the

The simplest solution is to set up a one-time-use token and embed
that
in your FORM data:
I usually use a session based token but i guess it the result is

Re: [PHP] Clearing pipe stream and a few other issues.
Permissions on a virtual server is the reason for running this script as a
cgi. It's not what prefer to do. However, this is only way php will work

know perl. If I had control of the apache server this would not be a

I have the script working, I just need to clear up these issues.

Re: [PHP] Site bloated by images
Good point, I didn't check all the images and probably had assumed that there was one that was huge. Another candidate to look at, is the number of file transfer threads that her server can maintain for each client, this is often limited. I have seen one occasion when a user cranked the number down to just a few (2 or 3) and transfer became very slow as some transfers had to wait on others to complete, but this was limited to pages with lots of images. this of course would be a server issue (apache or whatever) and not PHP. Seems also that browser security (firewalls) could be a factor as well.

It really comes down to how you build your application and how it
behaves on a POST. If the application is designed to post something
and come back to the same page, a redirect makes sense after the action
occurs. But then again you have to worry about how to transmit a
mesage back saying the action is done.
Honestly, i think the abuse of the re-direct is due to the commonly
used browser, IE. If you hit back an ugly message comes up warning
the person that it is going to re-post data, if they hit OK and you
protect against it (like the solution you give later in this
thread) your ok, but if they hit cancel, they get an 'Expired
Page'. The redirect avoids that issue.

If the server supports keep-alive connections the client most
likely will use the same connection to make the redirect.

Well, it depends what "usually is" (can be) before what you want to get
and the regex family your using. If it's PCRE, you may try something
like "\b\d{4} [A-Za-zÅØ]{2,20}" \b = "word boundary", it's basically
a word separator and it's not included in the result you get (since it's
more a "position" rather than a "string")
Also, you may notice a couple of 'special' characters in my expression
'Å + Ø' By putting them in they seem to work fine, but is this the

I think it is. IIRC what you define in a "class" (i.e. between
square-brackets) is quite fast; e.g. "[ab]" fastest than "(a|b)", is
that what you were asking?

Re: [PHP] Site bloated by images
MARG's suggestion is right on, I took a look at some of the images, and while relatively small at 250 x 300 pixels, they end up displaying in an image statement that limits them to 15 x 16 pixels (or there abouts) on the finished page. If you only need 15 x 16 pixels, resize the files to that size and reduce the transfer size to about 5 percent of their current size. What you are doing is transferring all the pixels then asking the browser at the destination to resize them. This will eat up bandwidth very fast. If you need to keep the original image with lots of pixels, keep copies on your work machine and not on the server. good luck, Warren [EMAIL PROTECTED] At 04:51 PM 2/16/2006, Angelo Zanetti wrote: MARG wrote: Hi, I have this site on http://www.dte.ua.pt/portulano/ The problem with it is that it tak ages for the images to appear.

I've seen a fair number of PHP applications that had nothing to do with Hypertext... GD, libPDF, Ming, GTK... The list goes on. I was hoping for some inspiration from the ancient poll on php.net from the last time we went through this. Some of the suggestions were very... creative. :-) Personally, I don't really care what the acronym's words say. I know it's "not just for text anymore" Actually, I think most of the non-text Modules were there when we did the last acronym change. And certainly there were many heavy-duty applications whose "Hypertext" component was not the primary focus of PHP. So, fwiw, I'm voting -1 on the re-invention of PHP as an acronym. I could be swayed by a REALLY good acronym that expressed what I really thought PHP was all about... But I defy anybody to fit that all into 3 words that come out to PHP.

[PHP] Clearing pipe stream and a few other issues.
ok, I'm not sure how to explain this but here goes.. I have a php script being used as a cgi to get around certain permission issues. Its not what I wanted but is basically working. Running through the cgi-bin has been much more difficult however, for example, 1. I need to clear or reset the stream because on occasion, I am get variables from a previous submission to the form. Not sure how to do this. 2. I have having trouble using the header function. Its says that the header is already been sent. I can only assume at this point its because of the #!/usr/local/bin/php -q at the top of the script required for cgi's. I may be wrong. I may not even need the header. 3. The formatting is coming out in plain text..The html code is not executing. Here again I believe its a header content issue. here is the code: Thank You, $sender_name Your secret message has been sent."; ?> here is the result: Thank You, David Your secret message has been sent.

[PHP] A quick Regex query

I am using the following:

to extract data like:
1000 Øslo
How can I alter the above to limit to ONLY 4 digits, or in other words
exclude:
11000 Beograd
Please note that what I am extracting from is NOT at the begining of a
line, so I can't use the ^ first.
Also, you may notice a couple of 'special' characters in my expression
'Å + Ø' By putting them in they seem to work fine, but is this the best
way of doing it?

Check your Apache error log for messages. It SHOULD have messages about having successfully restarted when you restarted. If it doesn't, you only THINK you re-started Apache, and didn't. I've seen cases where apachectl (or maybe /etc/rc.d/rc.init/S10apache) would fail to kill/start Apache, but would output a message that it HAD done so. :-( More likely, however, you've got error messages about the .so files not being valid or not being found. They have to be where php.ini says they should be, and if your php.ini is out of sync with your pecl, then pecl put them someplace else. :-( -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you want Apache error logs, you can just configure Apache to generate them and put them where you want them... They usually end up in /var/log/httpd/error.log (or somesuch) by default, though with older Apache from source maybe in /usr/local/lib/apache/logs/error or similar. It's quite likely that you HAVE error logs, but just don't know where they are :-) locate error_log might find them for you. If the error logging was turned "off" in Apache config, you want to find your "httpd.conf" file: locate httpd.conf and turn it back on. Installing a whole new Apache to turn on error logging is like buying a new car because the cigarette lighter is missing... > So I downloaded apache 2.0.55.

In the Httpd.conf? php.ini traditionally went in /usr/local/lib/php.ini Many OS-installed distros (RPMs et al) put it in place like: /etc/php.ini /usr/local/etc/php.ini locate php.ini might be instructive. You can put php.ini anyplace you like ; You just have to convince Apache+PHP where to find it. PHPIniDir directive in Apache 2.0 simplifies this. PHPIniDir would need to go in httpd.conf file. All these "locate xyz" things assume you can SSH (telnet?!) in to your server... If you ONLY have FTP access, then it is unlikely to be useful... It is equally unlikely, with only FTP access, that you'll be able to successfully install a new Apache anyway, much less get it to run (you'd have to have root access).

Check for your bug here: http://bugs.php.net and also on the GD site. If it's not there, post the raw text string somewhere on the 'net, file a bug report, and link to it. One Issue: Browsers are notoriously forgiving and capable of rendering botched images, as well as image formats that GD doesn't know about (EG, AOL's image "format"), so the browser test is not really conclusive.

Hi gang:
In a previous post (i.e., [PHP] Strange response to MySQL query) I
was trying to save a BLOB as a file, namely using an "INTO DUMPFILE"
query.
If you are the system admin, and have all the system permissions,
then this is not a big problem. However, if you aren't, then getting
MySQL to dump a file becomes very problematic with respect to getting
the right permissions to accomplish the task.
So, I found a way around it. I am sure that others have thought of
this before me, so I'm not claiming credit and I am sure that this
solution is obvious to some -- but, it's just that I searched
literally hundreds of posts and spent considerable time without
finding an answer. The following is the result of my tinkering. So
here goes:
First, on your site create a file called "my_image.png"
Second, give it 777 permissions.
Third, in your code after opening the dB, grab the image from MySQL:
$dbQuery = "SELECT image";
$dbQuery .= "FROM $your_table ";
$dbQuery .= "WHERE image_Id = $pageNum";
$result = mysql_query($dbQuery) or die("Error: ".mysql_error());
Forth, drop the image into a variable:
$fileContent = @mysql_result($result, 0, "image");
Fifth, create an image from a string (a great function here):
$original=imagecreatefromstring($fileContent);
Sixth, save the image.
imagepng($original, "my_image.png");
And Bingo, the image is now the "my_image.png" file.
Any comments or suggestions are welcomed.

I dunno why you are having trouble losing \r and \n, since it's not
tricky...
But forget all that, and consider this:
$Email = $_POST['Email'];
$Email = str_replace("\r", "\n", $Email);
$Email = explode("\n");
$Email = $Email[0];
if (trim($Email) !== trim($_POST['Email'])){
die("spammer");
}
$Email = trim($Email);
Now, whatever other crap headers they added, they're gone, and you can
safe go on with life, secure in the knowledge that $Email, even if
it's not valid, is at least not header-injected with all kinds of crap
you dont' want.
You should do this for all variables that get embedded into headers.
You can't do this on the Body, of course, so they still might be able
to trick things with a cleverly-composed $Email to set up the
Mime-type, and then an html "enhanced" (cough, cough) Body.
Assuming you don't allow HTML "enhanced" email in the first place, do:
$Body = striptags($_POST['Body']);
Should take care of it.
The advantage of this technique is that it doesn't just focus on the
headers you know are "bad" while possibly ignoring other headers
you're not aware of.
It forces the $Email to a single line, which cannot have multiple
headers in it.
Sort of like "whitelist" better than "blacklist"

First, bypass the problem entirely, and look for an RSS / XML feed of the same content. Or a SOAP source of the content. Or RPC. Or WebDAV. Or *anything* but web-scraping and parsing HTML, which should be your "last resort" If Regex seems high-maintenance, consider using just strpos and explode and other simple string functions.

If it's not "wrong" for me to push the "back" button, why are you
breaking it with all your re-directs :-)
Seriously, I think the re-direct feature is the most over-used and
abused feature.
It's also wasteful of HTTP connections which will kill a busy server,
and does not scale well.
I generally find that if I sit down and figure out why there is a
re-direct, and then code the application so that I don't need the
re-direct, because I've gathered/generated the information in advance
or re-structed things to not need the re-direct, I end up with a far
more clean and sensible design in my code-base.
YMMV

Where does $email_address come from?
Unless we know that, we can't discuss header injection...
Also, this:
$body = $body . "...";
is more usually expressed as:
$body .= "...";
And, finally, your '\r\n' are not going to work.
Only \\ and \' are special inside ''
You need "" for \r\n to be special.

[PHP] php.net has turned Japanese [SOLVED]
Yesterday, while searching for a way to programmatically do HTTP Basic Authentication, I ended up visiting the Japanese language version of http://php.net/ The User-Contributed notes that matched my search were in English, so I thought nothing of it, and successfully completed that task. Today, I type something like: http://php.net/mysql_affected_rows And I end up on the Japanese site, with no /ja/ in the URL. I suppose this is a "feature" and a nifty one at that... ... for those users that can actually read Japanese. E... How do I turn this feature off? :-) :-) :-) Actually, I'd have to say it's a bug that viewing the site ONE TIME in some language forever ties one to that language... I did nothing explicit to "choose" Japanese, other than clicking on a link in a search engine -- said link having nothing about it to indicate I was switching to Japanese. Aha! I just click on a link to get to a URL with /ja/ in it, then change the /ja/ to /en/ and then it default back to English when I use a short-cut URL again. I think this post can now be condensed into a plea: When the php.net site is utilizing a short-cut URL, perhaps an additional navigational element should be added to switch languages, as it is not at all obvious how one should switch. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Saving a BLOB image to a file (SOLVED)
Hi gang:
In a previous post (i.e., [PHP] Strange response to MySQL query) I
was trying to save a BLOB as a file, namely using an "INTO DUMPFILE"
query.
If you are the system admin, and have all the system permissions,
then this is not a big problem. However, if you aren't, then getting
MySQL to dump a file becomes very problematic with respect to getting
the right permissions to accomplish the task.
So, I found a way around it. I am sure that others have thought of
this before me, so I'm not claiming credit and I am sure that this
solution is obvious to some -- but, it's just that I searched
literally hundreds of posts and spent considerable time without
finding an answer. The following is the result of my tinkering. So
here goes:
First, on your site create a file called "my_image.png"
Second, give it 777 permissions.
Third, in your code after opening the dB, grab the image from MySQL:
$dbQuery = "SELECT image";
$dbQuery .= "FROM $your_table ";
$dbQuery .= "WHERE image_Id = $pageNum";
$result = mysql_query($dbQuery) or die("Error: ".mysql_error());
Forth, drop the image into a variable:
$fileContent = @mysql_result($result, 0, "image");
Fifth, create an image from a string (a great function here):
$original=imagecreatefromstring($fileContent);
Sixth, save the image.
imagepng($original, "my_image.png");
And Bingo, the image is now the "my_image.png" file.
Any comments or suggestions are welcomed.

I had a similar problem with my contact form and went down a similar
path of trying to clean up the user-input with regexes. They caught
some of the spammers but they kept trying and were eventually able to
get around them.
I posted this to the php-general list as well and two users suggested
I try the following:
- add a numeric limit to your email field to prevent spammers from
dumping huge blocks of email addresses:
if (strlen($email)>255) echo "Scram!";
- after you have tried to filter/clean the e-mail address, test it
again with a function that determines if the input is a valid email
address. I used this validation function to check email addresses,
from an article on "Validating Emails with PHP" on Developer.com:
http://www.developer.com/lang/php/article.php/10941_3290141_1
function validate_email($email)
{
// Create the syntactical validation regular expression
$regexp =
"^([_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.[a-z]{2,4})$";
// Presume that the email is invalid
$valid = 0;
// Validate the syntax
if (eregi($regexp, $email))
{
list($username,$domaintld) = split("@",$email);
// Validate the domain
if (getmxrr($domaintld,$mxrecords))
$valid = 1;
} else {
$valid = 0;
}
return $valid;
}
$email = "[EMAIL PROTECTED]";
if (validate_email($email))
echo "Email is valid!";
else
echo "Email is invalid!";
I implemented these two steps to a function that was similar to yours
and haven't had a breach since.
Best of luck,
- schnippy

Re: [PHP] Clear POST variables
How do I clear out the POST variables, or the variables that I have set from the POST variables, so that when the page is refreshed it will not resubmit. I have tried unset() and have tried to set it to and empty value, but it doesn't seem to work. You can clear out POST by doing this: $_POST = array(); But that won't do anything in your case because every time the page is refreshed the form is resubmitted (and POST is repopulated). You need to find a way to ensure unique entries in the database. One option is to store a hidden, random value in the form, like a timestamp or the md5() of a random value. Then store this in the db, along with the other data. Put a unique index on that column so that the same random value cannot be inserted multiple times. (In other words, the form would need to be reloaded, then resubmitted for the data to go into the db.)

RE: [PHP] Clear POST variables
I agree. I always redirect my users to a "GET" page after a successful
posting so that they can't click the browser's "RELOAD" button to cause
a second posting. I have used this technique in dozens of PHP
applications with hundreds of users, and it really cuts down on
duplicate entries.
On the "POST" page I usually add something to the session variables that
causes the user to see a "Your changes have been saved" type message on
the "GET" page that they're redirected to.

I'm curious to hear what others say, but I tend to build into my

[PHP] Secure Mail Form using PHP

in the archive, so I'm sorry if I'm going over old ground.
I'm trying to make sure my email form cannot be used for spam or
injecting additional code and addresses in any way.
So far I'm able to remove bcc, cc, to, etc but unable to remove \n & \r.
If I could do that I'd consider it fairly secure. As you'll see below,
I've been trying various ways of doing it.
// CHECK FOR SPAM ATTEMPTS AND REMOVE THEM
$Email = stripslashes($Email);
$Senders_Name = stripslashes($Senders_Name);
$Message = stripslashes($Message);
$recipient = stripslashes($recipient);
$subject = stripslashes($subject);
$Email = preg_replace( "/[\n\r]+/", " ", $Email );

I'm not really sure what you're trying to do, but I assume you want to
keep the four(?) spaces when you output the data. If you're going to
display it using HTML, you have to replace the spaces with -
otherwise HTML truncates the excess whitespace. Try using REGEX:
$contents =3D file($filename);
echo preg_replace("/\s/", " ", $contents);
This regular expression will replace all whitespace
(spaces/newlines/carriage returns) with the character , which in
HTML yields a blank space.

Re: [PHP] installing php 4.4.2 on windows system
Hi Paul, I have been developing a php website. I have been ftping my php web pages to a webserver and that works hkowever I don't have an error log on the webserver. So I downloaded apache 2.0.55. I am doing a manual installation and I am at the point where it tells me where to place the php.ini file. The instructions tell me to put the file in a number of places. The directions told me that if I were using apache to use the PHPIniDir directive. My question is where do I put the php.ini file? Where do I put this Directive? In the Httpd.conf? Under Windows it didn't use to be necessary to make Apache explicitly point to the ini file (at least: for all Apache 1.3.x versions). Rather, the trick used to be to simply place the php.ini file somewhere in the path that has been set for all Windows applications. Normally, the 'windows' or 'winnt\system32' directories do the trick. If you're working under NT, 2000, or XP give the latter a go and restart Apache. Chances are it still picks it up swell. If it doesn't, then indeed perhaps as of Apache 2 you need to explicitly make Apache point to the right file. Cheers!

Re: [PHP] Ternary operators
sorry - I have had a php5 CLI at hand for so long I forgot that 'php -r' is not available in v4. that said the 'php -a' option also works (although I always find the interactive mode odd to work with) Kevin Kinsey wrote: Carl Furst wrote: Well, I tried something simple... $ php -r 'echo "hello world\n";' Error in argument 1, char 2: option not found r Error in argument 1, char 2: option not found r Usage: php [-q] [-h] [-s] [-v] [-i] [-f ] php [args...] -a Run interactively -C Do not chdir to the script's directory -c | Look for php.ini file in this directory -n No php.ini file will be used -d foo[=bar] Define INI entry foo with value 'bar' -e Generate extended information for debugger/profiler -f Parse .

Still, not too hard to open an editor, code a tiny script, and run it from the CLI in either PHP4 or PHP5. Let's all learn to test things, eh?

Re: [PHP] Help! Apache 2.2 gives segmentation fault errors with PHP.
Hi all, Yesterday I had trouble when configuring Apache 2.2 with PHP 4.4.2, which caused Apache to crash (segmentation fault) when calling various PHP functions. Just before heading home I encountered the source of the issue, as well as the solution. The hint to the answer resided in the /var/log/httpd-error.log file: > And the /var/log/httpd-error.log file mentions the following (at the end): > [...] > PHP Warning: Function registration failed - duplicate name - bzopen in > Unknown on line 0 > PHP Warning: Function registration failed - duplicate name - bzread in > Unknown on line 0 > [...] > ..many more similar messages... This obviously hinted at these functions (i.e php4-extensions) somehow being doubly present and called. Issuing a 'pkg_info | grep php' command was most illustrative, and showed over a screen full of output like this: mod_php4-4.4.2_1,1 PHP Apache Module php4-bcmath-4.4.2_1 The bcmath shared extension for php php4-bz2-4.3.10 The bz2 shared extension for php php4-bz2-4.4.2_1The bz2 shared extension for php php4-calendar-4.4.2_1 The calendar shared extension for php php4-crack-4.4.2_1 The crack shared extension for php php4-ctype-4.4.2_1 The ctype shared extension for php php4-dio-4.4.2_1The dio shared extension for php php4-domxml-4.4.2_1 The domxml shared extension for php php4-exif-4.4.2_1 The exif shared extension for php php4-extensions-1.0 A "meta-port" to install PHP extensions php4-gd-4.3.10 The gd shared extension for php php4-gd-4.4.2_1 The gd shared extension for php [...more lines where those came from...] Tadh!! there we go: indeed several extensions were somehow not removed properly when a previous upgrade to PHP 4.4.2 (from v4.3.10) was performed! As to the reason for this, go figure, I always install from the ports by doing a 'make' 'make deinstall' 'make reinstall' sequence when upgrading... Anyway, manually removing all PHP extensions using the various individual 'make deinstall' sequences (and bluntly pkg_delete for pear). Then, I cleanly redid the process for installing mod_php4 and the extensions, and now all is working fine! Tnx for thinking along with me, and beware of this potential pitfall! :) Cheers!

Re: [PHP] please help me I try to post my question to Php.net 2-3times
wvolks wrote "...but when I display data in text file it compress space in
each lines..." Sounded to me like he wanted all the blank spaces he put
into the string, but when he "displayed" it, the spaces were gone. Since
html ignores more than one blank space between printable characters, I
suggested he substitute for the blank spaces. He also said "I want
fixed possition . please help me ?", and so I tried to help.

is it just "whitespace" or are there also commands in it like \t or \r ?
Otherwise just replace the whitespace with "" like
$filename = "c:data.txt";
str_replace(" ", "", $contents);
echo $contents;
Something like that?
