Re: [PHP] ampersands in href's
The simplest way to make sure everything work well regardless of what the
values are:
?
$url = somepage.php?var1=.urlencode($var1).var2=.urlencode($var2);
echo a href=\.htmlspecialchars($url).\;
?
htmlspecialchars() changes characters '', '', ''', '', '' into the HTML
equivilant. And yup, you should do this for all *ML pages as long as the
thing being printed is not part of the mark-up syntax.

I think you have the idea. The 's are used to seperate the various
variables. If you want to set $p to something like 'Tom Jerry' then
personally I'd do something like:
?php
$p = Tom Jerry;
$s = Cat Mouse;
printf(a href='{$_SERVER['PHP_SELF']}?p=%ss=%s, urlencode($p),
urlencode($s));
?
That's nice. To get more specific (because my code varies a bit from
yours and I don't wanna mess up the ) and ' and s:
$p and $c are actually row ID numbers so up to 3 digits. So for example
if
$p=1
$c=32
I was wanting to see a URL of
http://foo.com?r=1c=32
In that case, you can simply echo them out, once you're sure that $r,
and $c are actually integers.
I forgot to mention that above I did $r = intval($_GET[r])
!
Thanks, everyone!
echo a href='http://foo.com?r=$rc=$c'whatever/a
if not(sure they're integers, you could always
printf(a href=\http://foo.com?r=%dc=%d\;whatever/a, $r, $c);
Alternatively you could $r = (int)$r;
or echo a href='http://foo.com?r=; . (int)$r . c= . (int)$c .
'whatever/a;
There's more than one way to do it...
so was this the way to go?
//Make a thumbnail table of contents to display in the left sidebar
while ($sidebar = mysql_fetch_assoc($sidebar_result)) {
$sidebar_thumbnails[] = a class='img-link'
href='{$_SERVER['PHP_SELF']}?p=%pc={$sidebar['art_id']}, urlencode($p)'
title=\{$sidebar['art_title']}\img class='sidebar-img'
src='{$image_dir}{$sidebar['art_thumbnail']}' width='50' height='60'
border='0' alt=\{$sidebar['art_title']}\ //a;
}
?
Thanks in advance!

Hi,
If I want to make a link to a URL which includes some GETs can I just
do:
a href='{$_SERVER['PHP_SELF']}?p={$p}c={$s}' ... etc etc
or must I escape the ampersand somehow?
TIA,

Re: [PHP] Re: 1 web site, 3 servers, 3 countries - best practises?
I think he wants mirror, sort of... I will do this if I were you: Select the server wif the most bandwidth. Call this the master. The other 2 are slaves. To sync files: == Enable network file system server on the 2 slaves. Export the htdocs directories. Setup the master to mount the exports. Setup file monitoring tools (maybe fam?) on the master to copy new files to the mounted slave directories when alteration of files in htdocs is detected. DO NOT instead mount exports of the master's htdocs on the slaves otherwise the slaves will be very slow in serving out files. Of course, you have to enable security - things like IP restriction/encryption on the NFS. To sync database: = Use database slaving tools? If you are using MySQL, see http://mysql.hjc.edu.sg/doc/mysql/en/replication-intro.html. All updates from ANY server must be done at the master though. Or you can just host the SQL server at the master. All queries goes to the master.

Re: [PHP] Forms on PHP
Refer to the following line numbers:
01 ?php
02 // Start of PHP code - Extract values from form.
03 /* Other values read */
04 $n=$_POST['n'];
05
06 // Pass the data from the form to lightcurve_csharp
07 $command=./lightcurve_csharp $a $i $e $lomega $bomega $lambda $n;
08 $result=`$command`;
09
10 $form_submitted=$_POST['form_sumbitted'];
11 if (isset($form_submitted)) {
12 if ($form_submitted) {
13 echo 'The form has been submittedbr';
14 unset($form_submitted);
15 }
16 } else
17 echo 'The form has not been submittedbr';
When the user first load the page, no data was posted. So there was no
$_POST['form_sumbitted'] available. Line 10 will cause $form_submitted to
contain the NULL value (I think). $form_submitted will evaluate to FALSE at
line 12. Thus it will not display any message.
By the way, by doing line 10, $form_submitted would have been set regardless
whether there is $_POST['form_sumbitted'], and line 11 will evaluate to TRUE
always. Thus you will never ever see the 'form not been submitted' message.
Anyway, when you posted for the first time, $_POST['form_sumbitted'] is
available. The 'The form has been submittedbr' message will be printed.
After that, when you press Reload button on the browser, the post data will
once again be sent from the user. (This is the behaviour of reloading a
posted page. In Internet Explorer there should be a message dialog box
asking the user whether to resend form data in order to refresh.) Reposting
the data during the reload means that there will be
$_POST['form_sumbitted'], thus once again the 'form hass been submitted'
message.
In order to prevent this from happening, you should do a header('Location:
success-page.php') on a successful submit. This is so that at the redirected
page, the user would not have resent data even if he press the Reload
button.
Hope this helps
-Leon

Re: [PHP] PHP form POST question
When you access /foo, the server will redirect the client to /foo/ (because
it is a directory). At the redirected page, the post data will not be sent
again by the browser thus there are no _POST values.
Try using action=/foo/. That may work.

Subject: [PHP] PHP form POST question
I just narrowed something down about forms and POST and would like
education. In the following scenarios, all work except #4. $_POST is null.
Why is that?
Setup:
1) Running on localhost
2) /foo/index.php has the following:
? var_dump($_POST); var_dump($_GET); ?
3) /index.php contends vary per scenario (below)
Running RHEL 3, all updates (PHP 4.3.2).
SCENARIO 1:
/index.php contains the following:
form method=get action=/foo/index.php
input name=foobutton type=submit
/form
In this case in /foo/index.php $_GET has the right value, i.e.
array('foobutton' = '');
SCENARIO 2:
/index.php contains the following:
form method=get action=/foo
input name=foobutton type=submit
/form
In this case in /foo/index.php $_GET has the right value, i.e.
array('foobutton' = '');
SCENARIO 3:
/index.php contains the following:
form method=post action=/foo/index.php
input name=foobutton type=submit
/form
In this case in /foo/index.php $_POST has the right value, i.e.
array('foobutton' = '');
SCENARIO 4:
/index.php contains the following:
form method=post action=/foo
input name=foobutton type=submit
/form
In this case in /foo/index.php $_POST is NULL.
HUH? Why is $_POST empty? Is Apache doing something to kill the form's
post information when it has to resolve /foo to /foo/index.php?
