Yah, I think I will use a global for now... Until I can think of an
alternative coding approach.
Have a good one!

Ah, hehe... Oh, basically I am trying to write a plugin for the
Textpattern CMS:
<http://textpattern.com/>
processTags() is a core TXP function... Basically, it parses any TXP
template tags (<txp:function_name atts="foo" />).
Long story short, I am am modifying the processTags() function so that
it looks for class methods when parsing template tags, vs. looking for
regular functions.
Thanks again Casey! I really appreciate your help. :)

i have two select tags as part of a registration form, city1 city2 where
city1 has a list of regions and similar for city2
there are different regions for city1 and city2 so instead of all the
regions appearing one after the other i would like to create a blank option
followed by the next set of regions for formatting purpose only.
ex=
<select name="city1">
<option <?php if ($city1=="region1"){echo "SELECTED";}?>
value="region1">Select region1</option>
<option <?php if ($city1=="nameofregion1"){echo "SELECTED";}?>
value="nameofregion1">nameofregion1</option>
<option <?php if ($northisland=="0"){echo "SELECTED";}?> value="0"></option>
<option <?php if ($city1=="nameofregion2"){echo "SELECTED";}?>
value="nameofregion2">nameofregion2</option>
<option <?php if ($northisland=="1"){echo "SELECTED";}?> value="1"></option>
</select>
<select name="city2">
<option <?php if ($city2=="region2"){echo "SELECTED";}?>
value="region2">Select region2</option>
<option <?php if ($city2=="nameofregion1"){echo "SELECTED";}?>
value="nameofregion1">nameofregion1</option>
<option <?php if ($northisland=="2"){echo "SELECTED";}?> value="2"></option>
<option <?php if ($city2=="nameofregion2"){echo "SELECTED";}?>
value="nameofregion2">nameofregion2</option>
<option <?php if ($northisland=="3"){echo "SELECTED";}?> value="3"></option>
</select>
from a php validation perspective if a user does not select any of the
regions or both the regions i am displaying an error message asking them to
either select 1 region from either city1 or city2
as of now there is a blank option being displayed which is working fine, i
am having an issue with the php validation.
until i introduced value=0 my rules for validating the select tag were:
1. user cannot leave both the select tags with the default option which is
"Select region1" & "Select region2"
2. user cannot select both the regions from city1 & city2 select tags
the code of 2. is
if(!($city1 == "region1") && !($city2 == "region2"))
{
$error.="Please select only 1 Region<br />";
}
now by introducing <option <?php if ($northisland=="0"){echo "SELECTED";}?>
value="0"></option> there is a conflict with the above php validation code
used in point 2.
1.
is it correct to use 1,2,3 as part of the following <option> tag or should i
only use 0 everywhere
<option <?php if ($northisland=="0"){echo "SELECTED";}?> value="0"></option>
<option <?php if ($northisland=="1"){echo "SELECTED";}?> value="1"></option>

how can i get around the conflict that is being created by introducing this
value=0 with

{

}
as i need the above php code and i also need the blank space for formatting
purpose
please advice.
thanks.

Code wise your form options are too bulky and you need to look at slimming that
down like below. Not that my example is prefect but easier to control the
option enviroment.
echo "<select name='city1'>";
for($d=1; $d<=2; $d++)
{
if($city1 == "region$d"){
echo "<option selected value='region$d'>region$d;
}ELSE{echo "<option value='region$d'>region$d;}
}
echo "</select><BR><select name='city2'>";
for($d=1; $d<=3; $d++)
{
if($city1 == "region$d"){
echo "<option selected value='region$d'>region$d;
}ELSE{echo "<option value='region$d'>region$d;}
}
echo "</select>";
Also I would use some onblur or onsubmit javascript for form validation
submitting and then showing the error is NOT a good way to validate a form.

Hi,
I am a new php user and I have a question, for which I couldn't find any
answer.
I'd like to restrict php code to access the filesystem. I'd like to have
only one directory where the php code can write, create or read files,
and an other directory hierarchy where the php codes present. I need
this to avoid php code to rewrite other php code in case of bug and/or
an attack.
I already tried the open_basedir directive, but it couldn't work because
in this case the executed php have to be in the accessable directory
hierarchy.
Thanks,
Gabor

it depends, if you run your own server (you have root password). then you
can do something
about this. but if you run on shared server, i don't think you have a lot of
options.
if you afraid the php code to rewrite other code (rare case). just chmod all
the php files
to 644.

Hi,
Thank you for the answer.
I am running my site on a shared server, but I can overwrite the options
in the php.ini file. Unfortunately php runs as my user, so changing the
permissions to 644 doesn't work, php is still able to write anything.

ok.. your hosting enable the php suexec. i afraid there is not much you can
do to modified the php.ini. you may use ini_set() or the .htaccess to
override
the value anyway.
one thing you can do. sanitize input and make sure you code good :p

Are you saying that you want to use one file to allow people to
write to your server without allowing them to overwrite other files?
Try creating a directory, chmod 777 if needed, and then in your write
routing, disallow periods (.), slashes (/), backslashes (\), et
cetera. And you may also want to look into escapeshellarg() and
escapeshellcmd() depending on your code. You can also chmod the
directory and all files within where the PHP files are located to 644,
which will disallow writing if Apache isn't running suExec.

Hi,
I have the code of a function to generate a random 10 character long
password following my signature.
To test it i do:
$clearpass = create_pass();
print('Clear: ' . $clearpass);
die();
But the output is only "Clear:"
Why isn't it working ?
Any help would be appreciated.
Warm Regards,
Mário Gamito

function create_pass ()
{
$length=10;
$password = "";
$possible = "0123456789abcdefghijklmnopqrstuvxz";
$i = 0;
while ($i < $length) {
$char = substr($possible, mt_rand(0, strlen($possible)-1), 1);
if (!strstr($password, $char)) {
$password .= $char;
$i++;
}
}
return $password;

Just wanted to avoid installing and maintaining a LDAP server and

Perhaps I am underestimating it, but just to read one URI like request,
find the data and send it back in some form, does not look difficult to
implement. We do not need full LDAP support, just to feel Thunderbird
and Squirrelmail address books. Both can't edit LDAP yet anyway.

That's a DNS issue, not a PHP issue. Is this a shared web host,
or one for which you have root access? If you have at least shell
access without a jail (chroot), try PING'ing the domain from the
server and see what happens. It could even be something as simple as
a typo in the domain, but most likely it's a DNS resolution problem.
If you want to test your script on a different server, let me know
and I'll set you up with a temporary account on one of mine.

Sounds like you're using literal quotes here, Mary. Single quotes
('like this')take all data between them as literal, while double
quotes ("like this") translate things within.
$a = "Hello!";
$b = "I just wanted to say: $a";
$c = 'I just wanted to say: $a';
$d = "The quick brown fox jumped over the lazy dogs.\n";
$e = 'The quick brown fox jumped over the lazy dogs.\n';
The above will output as follows:
$a: Hello!
$b: I just wanted to say: Hello!
$c: I just wanted to say: $a
$d: The quick brown fox jumped over the lazy dogs. (with a newline)
$e: The quick brown fox jumped over the lazy dogs.\n
You may instead want to use HEREDOC syntax.
$text =<<<EOT
This will allow for actual newlines to be carried over.
This also means that Windows-vs-Linux-vs-Mac newlines
are translated exactly as they were entered, so if you're
typing the data into the HEREDOC in a standard Windows
environment, you'll have \r\n, whereas Linux will have \n, and
Mac will have \r. Keep in mind, in a HEREDOC, those
newline characters will not translate, but variables will.
$b
EOT;
As always, if you want a newline after the final text is typed,
include one full blank line after. And always end your HEREDOC by
typing the signifier as the first character on the line.
Sorry if this is "dumbing it down" for you, but I wanted to take
the opportunity to not only address what may be your problem, but also
put this tidbit into the archives with the question you asked, since
someone down the road may very well find your question with that
problem. ;-)

Because it's not there. A lot of times, when you don't have a

lead to a 404, like in your case. ;-P

If you do have a index.php file in that directory and you are sure the path is
correct check the chmod and chown of the index.php file.

A lot of people don't realize, but if you're using Linux, CUPS has
a nice print-to-PDF-file option. It's not native PHP, of course, but
it's a nice, quick, reliable alternative.

Hi,
I wrote a little registration routine, which will send a confirmation letter to
the user with a random number in the message body (my site is on a host, so I
can't write in the subject, and ask the user to reply), which can be clicked
then, and my site will finish the registration. My big problem is, that this
host inserts an X header to the mail which identifies my PHP script as the
X-PHP. As I recognize, this header adds a huge number to the spam score. Is
there any possibility, to reduce the other scores? By the way, what counts most
in a spam?
Thanks,
SanTa

Paul Graham wrote an interesting essay several years ago about
that, including some great real-world examples using Bayesian filters
and scores. I'd recommend giving it a look:
