$result is not an object. why not lookup in the manual what mysql_query()
returns you?
as you have already been told: don't mix mysql_*() function called at random
with
calls to what seem to be PEAR DB methods.
problems with PEAR should be directed to the pear specific list btw.

Hello,
Show us the full context of the code. The example you give us will work fine
but that doesn't tell us what's really going on in your code.
Here is the function I use to allow french special characters in the subject
line (copied from german university tutorial
http://www-cgi.uni-regensburg.de/~mim09509/PHP/list.phtml//www-cgi/home/mim09509/public_html/PHP/mail-quote.phtml?datei=%2Fwww-cgi%2Fhome%2Fmim09509%2Fpublic_html%2FPHP%2Fmail-quote.phtml%2Crfc822-syntax.txt):
function quote_printable($text, $max=75){
/* $text ist ein String (mit neue Zeilen drin), $max ist die max. Zielenlaenge
Ergebnis ist auch ein String, der nach rfc1521 als Content-Transfer-Encoding:
quoted-printable verschluesselt ist.*/
$t = explode("\n", ($text=str_replace("\r", "", $text)));
for ($i = 0; $i < sizeof($t); $i++){
$t1 = "";
for ($j = 0; $j < strlen($t[$i]); $j++){
$c = ord($t[$i][$j]);
if ( $c < 0x20 || $c > 0x7e || $c == ord("="))
$t1 .= sprintf("=%02X", $c);
else $t1 .= chr($c);
}
while (strlen($t1) > $max+ 1){
$tt[] = substr($t1, 0, $max)."=";
$t1 = substr($t1, $max);
}
$tt[] = $t1;
}
return join("\r\n", $tt);
}
function qp_header($text){
$quote = quote_printable($text, 255);
if ($quote != $text)
$quote = str_replace(" ", "_","=?ISO-8859-1?Q?" . $quote . "?=");
return $quote;
}
So, before I enter:
$sent = mail($destination, $subject, $content, $headers);
I have:
$subject = qp_header($subject);
That's all... As said before, the e-mail is sent, but the mail() function
returns false !
Thank you for your help
LS
And what code is checking the return value of mail()? Trust me, we've
all made stupid mistakes, they're nasty little buggers that can sneak in
and ruin anyone's day; best to include it since it might be relevant.

I'm wondering if there's a convenient way to globally add a final step for
apache w/php that will remove unnecessary whitespace from text/html before
it gets sent to the client. Some sort of global config like thing would be
ideal. For what it's worth we're using the smarty template engine too, but
I suppose I'd prefer a solution that doesn't depend on it. Maybe something
like another AddHandler?

Also consider mod_gzip (or mod_deflate), they will get you a LOT more
space savings than mod_tidy will, and should still work with every
browser made in the past decade or so ;)
From what I've seen, the CPU load induced by compression is quite
small, at least on my test site that had about a quarter million
pageviews (hence compressed documents) per day. Definitely worth the
enormous bandwidth savings!

I am going to do some thinking (typing) out loud here because I need to
come up with a solution to double-clicking on a form button issue.
The steps are;
1. Fill out form
2. Click 'Submit'
3. Data gets stored (including unique data and time stamp data in this
case....which should work out well)
If the process sees the unique data and a timestamp sometime within the
last minute it should ignore the subsequent attempt.
4. A reply is returned to the user based on the first click. The data
returned to the user would be different for each click, that is why this
is so important. The first data returned is the correct data.
My confusion is in this (as I have mentioned in the past couple of
weeks, most of the confusion is as a result of a lack of rest, which
leads to not thinking clearly, which leads to me feeling ignorant); upon
the second click, where I check to see if the data has been entered and
find that it has how do I get it to return the data back to the user. I
think I see it now......let's see.....if I;
Select * from foo where data is what it is and time is within last
interval that I decide upon;
if(1 == mysql_num_rows(that query up there)){
get that data for return to the user;
} else {
Insert data, do calcs, return data back to user;
}
Does that look reasonable, or am I missing something?
Thanks for any insight!

Aside from my previous gd problems, here's another problem. It appears that
PHP5 (for Windows anyways) does not support MySQL (which in itself is
riduculous), but here's my problem. I have a script I just downloaded that
works perfectly on Linux/Apche/MySQL/PHP5, but when I run it on Windows 2000
with PHP 4.4 I get a page full of errors. Lets forget about the errors, does
anyone have any idea how to get PHP5 and MySQL to work on Windows. I have
already tried 100 different variations of things from information I found
searching out this problem, but maybe someone has a new idea.
If it were me I'd just run this site on Linux, but this is for a friend who
wants to use IIS. If your curious the errors are below.
Thanks

The fact that you get an invalid resource error from a mysql_xxx()
function indicates that you do indeed have a working MySQL lib. Looking
at the error further indicates that you are not passing a valid mysql
result handle to the function. Please show us the rest of the code where
you perform the query and attempt to retrieve the result. Since I see no
errors about connecting to the MySQL database, I assume that you have
that part working.
Cheers,
Rob.

While it probably has nothing to do with your errors, mysql_numrows() is
a deprecated alias to mysql_num_rows(), which should be used instead.
As for your problem, have you checked the PHP docs on how to install
MySQL support for PHP5 on Windows?

I use apache2triad (http://apache2triad.net/) which is an AMP package with
PHP 5.
I vaguely remember the first time I installed it (on Win XP Pro though) I
got similar problems with MySQL. I uninstalled it and reinstalled as I
wasn't sure if I accidentally clicked a dialog box without reading what it
said then it worked ok.
HTH...
PS - I had GD working ok on a simple thumbnail generation script.

>From what I have been reading this is a known issue with PHP5. There is
something in the php_mysql.dll which is not compatible.
I wasted 3 hours today trying all the tips and tricks I could find, but the
bottom line is that it won't work.
This was my reason for posting to this group to see if anyone has any ideas.
Here is one of the many links I was looking at to try and solve this.

Subject: Re: [PHP] PHP 5, Windows, and MySQL
Activating MySQL in PHP 5 is pretty simple. Open the php.ini file and
uncomment the line for the extension that you want to use--php_mysql.dll or
php_mysqli.dll. Restart the web server.
Using the mysql functions is described in the php documentation.

I am going to do some thinking (typing) out loud here because I need to
come up with a solution to double-clicking on a form button issue.
[/snip]
Because the data is contained in session variables this became an easy
issue once I logiced it out
/*
* we have to find out if a double click occurred but we are going to
allow for a much longer time interval
* of 30 minutes in order to make sure that the ESN can be provisioned
again, just not today.
*/
$getESNDate = "SELECT `ezESN` FROM `test`.`provision` ";
$getESNDate .= "WHERE `updated` BETWEEN DATE_SUB(NOW(), INTERVAL 1800
SECOND) AND DATE_SUB(NOW(), INTERVAL 1 SECOND) ";
$getESNDate .= "AND `ezESN` = '".$_POST['psESN']."' ";
if(!($dbESNDate = mysql_query($getESNDate, $udc))){
echo mysql_error();
exit();
}
/* does it test positive for ESN within the past few minutes? */
if(0 != mysql_num_rows($dbESNDate)){

Isn't there a javascript method that you could use to accomplish the

That would be the Javascript method to accomplish the same thing. :-)
It's probably more efficient than a PHP-based solution, modulo the usual
Javascript caveats (user can disable, etc.).

JavaScript can't be used for such things, or at least it can't be relied
upon. What if the user has disabled JavaScript? Or what if the user has
specifically disabled the JavaScript behaviour you are relying on?
For example, some websites very wrongly try to disable right-clicking on
webpages. Firefox provides an option (I'm not sure if it is enabled by
default) that prevents pages from disabling right-click. So using said
JavaScript code to disable right-clicks is not a valid way of preventing
people from viewing page source or downloading files. The same would
apply to any other security measure; it'd be just fine to use JavaScript
to discourage multiple clicks, but it wouldn't solve the underlying
problem; he'd still have to solve the problem on the backend.

Egg Zachary. That was why I wanted a PHP method. Since the SESSION data
is set for the activation receipt I do not have to query the database
again, save for the initial query to check and see if the data exists.

I found that my own problem with double click was caused by simply not
updating the session flag early enough! i.e. before trying to do
anything with the database connection ;)

Hi gang:
I don't know who originally asked, but if you generate and use a token with a
session, you can prevent double posting (clicking).

Hi list.
Basically, I'm still learning new things about php and I was wondering if
things inside an if statement get 'looked at' by a script if the condition
is false.
For example, would this mysql query get executed if $number = 0 ?
If ($number == 1) {
mysql_query($blah)
}
I know that's not really valid php, but hope it gets my point across. I was
just wondering from an optimisation perspective, as I don't want sql
commands being executed when they don't need to be (unnecessary server
usage).
Thanks in advance for your responses.
Alex.

Stuff inside an if statement will be compiled (So it has to be free of
syntax errors and such), but it won't be executed unless the condition
is true.

I can't think of any language that processes the contents of a
conditional block when the test condition fails.

Rob.

Nope. That's the definition of an if statement (conditional), in any
language. If the text fails, the contents of the block never happen.

Thanks for your help with my other question, heres a new one for you.
I need to nest a variable, inside another variable. For example:
$($buildingname)level
How (if at all) is this possible?

Why? What are you doing that requires that that cannot be done with
associative arrays? As in, what is wrong with:
$level[$buildingname]
(I'm only guessing at the correct naming scheme)

I've never found a use for it myself, but yes.. php provides for 'variable
variables':
http://us3.php.net/manual/en/language.variables.variable.php
$a = 'varname';
$varname = 'test';
echo $$a;
> test

You were on the right track, but this isn't going to work.. for a couple
reasons:
$var = 1; # this is fine
$var2 = "$var"; # $var2 == 1 at this point
echo $$var2; # you're going to echo $1
Putting $var in double quotes makes PHP evaluate it before assigning it to
$var2, so you won't get $var but the value of $var (1).
If you did use single quotes, you'd get this:
$var = 1; # this is fine
$var2 = '$var'; # $var2 == '$var' (literal)
echo $$var2; # you're going to echo $$var
It seems like you might get $var2 evaluate to $var.. then with $$var have it
evaluate to 1, but doesn't look like PHP digs that deeply. When I ran it, I
got NULL back.
This might be what you were aiming for:
$var = 1; # this is fine
$var2 = 'var'; # remove the $.. then you can use single or double quotes
echo $$var2; # $var == var, $var == 1, this should output correctly
Good lesson in 'gotchas' though.

it's possible but probably an array is a better solution:
$someBuildinglevel = "foo";
$buildingname = "someBuilding";
echo ${$buildingname."level"}; // outputs "foo"
now go lookup variable variables in the manual to for your penance ;-)

I just wanted to add that Richards technique is a good way to go.
I often use something very similar, the only difference being that I
make the head() and foot() function methods in class (an instance
of the class being created by the global include file for the given site
e.g:
class Page
{
function Page() { /* setup page */ }
function head() { /* show header */ }
function foot() { /* show footer */ }
}
I find that the class has all the benefits of the
structure Richard proposed with the added benefit (my opinion :-)
that you can store page related data in the global 'Page' object
as and when you need to and use that data when you do the output...
the net result means you may probably end up polluting the global
space with less variables.
