[PHP] $_GET $_POST simultaneously

Re: [PHP] $_GET $_POST simultaneously
Browser history: I do not want it to contain any URIs to files which require some sort of id variable passed. Example: 1. http://www.entity.org/edit.php (should produce an error or redirect to entity list) 2. http://www.entity.org/edit.php?id=1 (should display editing interface) Now I really do not like to use redirects in case of errors. So I could constantly use (2) second form of URI, even in POST requests. But then, if I already have id in $_GET, why the redundancy of sending another id to $_POST? B.

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

Re: [PHP] $_GET $_POST simultaneously
If your question is a matter of Is this a good programming practice then I think it's ok. There are times when something like this could be really useful. Should people get into the practice of using this kind of thing? I think it really depends on the circumstances and there's definitely times when it would just make things more confusing which is bad programming practice in general. So unless there's a web server that looks for POST data and ignores any GET data sent (which I've never heard of but I'm guessing that someone's managed to create a web server at one point that did this.. on purpose or not), then I think this is an ok technique if there's not a simpler one that does the same thing. Simplicity is really the key, but it's nice to know that you CAN use GET and POST together if you want/need to. Just as long as it's not complicating the situation for no reason. -TG = = = Original message = = = Browser history: I do not want it to contain any URIs to files which require some sort of id variable passed.

Re: [PHP] strange sessions
Hello, Here's a link to a website demonstrating my problems: http://www.timburgan.com/problems/ You can download the code from the site or here: http://www.timburgan.com/problems/files/site.zip I'm experiencing some weird issues with sessions, and because I'm quite new to PHP and sessions.. I'm a bit lost. My use of headers also seems to be playing up. I'd really appreciate it if someone has time to assist me, look at my code, and solve some of my problems that are described below. On my website, there are 3 types of users: 1. Students 2. Staff 3. Admin There are many students, and students are able to login and edit their own page, but they have no rights to edit other student pages, staff pages, or any other pages. There are many staff members, and staff are able to login and edit their own page, but they also have no rights to edit other student pages or staff pages. BUT THEY ARE ALLOWED TO EDIT ANY OTHER PAGES. The admin is also staff member, but they are given admin status and therefore able to edit anything - including any students, staff, or content. When someone logs-in successfully, they are taken to the editing page. If the editing page is then closed and the user tries to navigate the site as any normal non-logged-in user would (by clicking the navigation links), the address bar in the browser changes, but the content stays the same and doesn't change. Also, when someone logs-in successfully, they are taken to the editing page. If the editing page is then closed they are returned to the original page they were trying to edit. If the user then clicks [edit this page] again, it says they do not have permission to edit this page.. even though they do! By the way- to login, staff are Joe (username password are both: joe) and Simon (username password are both: simon). Students are Tim (username password both: tim), and Grace (username password both: grace). Thank you very much for your time and assistance. I cannot thank you enough.

Re: [PHP] client information
A couple of things that mey help. I think phpinfo() will display all the system varables. These varables come from the web server so your web server documentation may help. Another thing that may work is implode ( ',' $_SERVER ) which should give you a (, comma) seperated list of $_SERVER (Not sure uf this works for assosiated arrays) and you can also see if the varable is there.

Re: [PHP] 2 dimensional array processing
A, I was wondering why your variable was named insert.
Anyway, that's easy too.
foreach($insert as $table = $fields) {
$fieldList = array_keys($fields);
$fieldNames = implode(',', $fieldList);
$fieldValues = ''.implode(',', $fields).'';
echo 'insert into '.$table.' ('.$fieldNames.') values
('.$fieldValues.')';
}
That puts double quotes around the values. I always use single quotes
around my text pieces since PHP doesn't parse what's inside them, thus
it's supposed to be faster.

tab2 [fields1] [fields5]
tab1 [fields2] [fields7]
You almost have it, you just need to set your loop up to handle
unlimited field/value pairs in your array.
One option is to structure your loop like this:
foreach ($insert as $table = $fields) {
foreach($fields as $field = $value) {
$fieldValuePairs[] = $field = $value;
}
$fieldValueStr = implode(',', $fieldValuePairs);
echo update $table set $fieldValueStr;
unset($fieldValuePairs);
}

how do I do 2 levels of nested loop with the first level looping
through the first level of the array and the second nesting through
the second. something like:-
foreach( $insert as $table = $fields ) {

[PHP] Get name of extending class with static method call
Hi list,
in PHP4 it was possible to get the name of the calling class with
debug_bcktrace(). Unfortunately this behaviour has been changed in PHP5. I
didn't find a solution in the archives.
Is there *any* way to get the name of the calling class?:
class Car {
function drive() {
// I need the name of the calling class here
// in this case it should be 'Porsche'
}
}
class Porsche extends Car {
}
Porsche::drive();
Any help is greatly appreciated!

[PHP] PHP5 sprintf() function borken
Today i think i found an bu in the PHP5 version 5.0.3 ( allready exits also in
the version 5.0.2 , i try this version also ).
When tryo one of this scripts:
$i_test = 0.085007667542;
$tm_total = sprintf('%.2f', $i_test);
echo $tm_total;
$i_test = 0.085007667542;
$tm_total = sprintf('%.2f', $i_test);
echo $tm_total;
$i_test = 0.085007667542;
$tm_total = sprintf('%.2f', floatval($i_test));
echo $tm_total;
i always get an other result. Some time it get a result like that:

That puts double quotes around the values.

[Though MySQL may be forgiving in this regard...]
$fieldValues = implode(', ', $fields);
would work on all standard SQL engines if ALL the fields were text (or
non-numeric).
Or, in MySQL, for integer/float as well, as MySQL lets you get away with
bogus (non-standard) apostrophes on numeric field values, so this will
work for MySQL even though it's morally wrong :-)
To make it really portable (standard SQL), you'd want to query your
database as to the type of each field and put apostrophes only around
non-numeric field values.
Or you could have some other way of keeping track of what's numeric and
what's not, of course.
I always use single quotes
around my text pieces since PHP doesn't parse what's inside them, thus
it's supposed to be faster.
It's not measurably faster.
Even apostrophes have *some* internal processing (for embedded ' and \) so
there is no real difference in speed.
Benchmark it on your own machine to confirm.

Re: [PHP] $_GET $_POST simultaneously
[EMAIL PROTECTED] wrote: If your question is a matter of Is this a good programming practice then I think it's ok. There are times when something like this could be really useful. There are many scripts I write which provide results for either GET or POST data interchangably, so that links or forms can be used in the other pages to fit in with their look/feel. As far as mixing GET/POST goes, one reason for doing it would be this: Suppose throughout your whole site, you are passing $username via GET. But you have a FORM on one page with other information being sent via POST, for the minor convenience benefits that POST provides. To *keep* your username usage consistent, you pass username in the URL being POSTed to. This makes perfect sense to me, even if some don't like the idiom. Should people get into the practice of using this kind of thing? I think it really depends on the circumstances and there's definitely times when it would just make things more confusing which is bad programming practice in general. So unless there's a web server that looks for POST data and ignores any GET data sent (which I've never heard of but I'm guessing that someone's managed to create a web server at one point that did this.. on purpose or not), then I think this is an ok technique if there's not a simpler one that does the same thing. It's trivial to configure Apache to allow only GET or POST (or neither) for any given directory: http://httpd.apache.org/docs/mod/core.html#limit Simplicity is really the key, but it's nice to know that you CAN use GET and POST together if you want/need to. Just as long as it's not complicating the situation for no reason. = = = Original message = = = Browser history: I do not want it to contain any URIs to files which require some sort of id variable passed. Example: 1. http://www.entity.org/edit.php (should produce an error or redirect to entity list) 2. http://www.entity.org/edit.php?id=1 (should display editing interface) Now I really do not like to use redirects in case of errors. So I could constantly use (2) second form of URI, even in POST requests. But then, if I already have id in $_GET, why the redundancy of sending another id to $_POST? Don't send the id in $_POST. That's too confusing -- to have the same thing coming in via two vehicles. You *can* do it, and consistently use either $_POST or $_GET to read the variable, and ignore the other one, but why send data you *know* you'll ignore? Is it just me or ... why on earth would you want to populate both GET and POST arrays through this obscure way of coding ? See above. If you really have a form where you dont have a clue wether your data comes from GET or POST, It's more like: I don't care if the other programmer asks for my content via GET or POST, I'll give it to him either way. Now what I am interested in is if this is valid behaviour regarding HTTP specification and if other platforms support this interference of GET and POST variables in request? Completely valid, and that's why PHP has settings in php.ini to determine precisely which ones over-ride with others in $_REQUEST (an array combining POST+GET+COOKIES) as well as in the global variables if you turn register_globals ON which you shouldn't. -- 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

Yeah, this is really better on an Apache list... but... http://httpd.apache.org/docs/mod/core.html#errordocument No, it has nothing to do with Apache. Apache doesn't open the file, PHP does. You could argue that PHP should try to throw a 403 on a permissions error, but the problem is that it is really too late in the game to do so once we get to the content handler phase where PHP lives. It could be hacked to do it a number of ways, but it wouldn't be pretty and it wouldn't be very consistent either since we would have to only do it if no output has been sent on the request yet. So a sub-request or an auto-prepend would both change the behaviour. Actually, as the naive PHP programmer, I'd only want it to happen if it were the file matching the original URI request rather than no content sent to the browser yet Consider: ?php /* index.php */ require 'connect.inc'; require 'authenticate.inc'; ? If index.php is not readable, then a 403 would make sense to me. But suppose index.php is readable, and so is connect.inc, but *not* authenticate.inc: chmod 644 index.php chmod 644 connect.inc chmod 000 authenticate.inc If authenticate.inc were not readable, a 403 sent because PHP can't read one of those files would just be morally wrong, even if no content went to the browser yet. Because it's real likely that *I* am sending a 403 as part of my script in authenticate.inc, using HTTP Basic Authentication as described in the PHP manual. You'd be confusing the HELL out of me to have PHP sending out a 403 because it couldn't read the included file after it already managed to read index.php and connect.inc At that point, the problem is not that the page is not readable, but some portion of PHP script is not readable, and I would expect PHP to know the difference. That may be an unreasonable expectation on my part, and maybe I'm just spoiled by PHP's exemplary behaviour in the past of telling me exactly which file where I managed to screw up, but that's what I expect from PHP these days. :-) I suspect that this makes it even more of a hack to try to do, and even less likely, if it's even possible to be less likely, that it will be done some day. Throw in some mod_rewrite stuff and having PHP figure out when to do 403, and when to complain that it can't read a file, will be probably be *way* too much hackery. -- 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

Sometimes when I write a PHP-script and upload it to a ISP through

If I do so, is it right that anyone can write a data to that folder? E.g.

If it's 777, they don't even need to write a PHP script to read/write it.
ANYBODY with a login on the same server, or anybody who manages to break
into that server, will be able to read/write this file.
One common practice is to chown/chmod the files that PHP needs to
read/write so only the PHP user can read/write them. If the PHP user (see
output of http://php.net/phpinfo) can read/write the files, but nobody
else can, you've raised the bar a little bit to access.
This then limits the access to PHP scripts.
Of course, some other user with a login can write a PHP script, load it in
their browser, and effectively be running as the PHP user and still
read/write your data, same as you.
If you think about this a bit, you'll realize that you've got a chicken
and egg problem: If *your* PHP script can alter the data, so can theirs.
If you make it so *their* PHP script can't alter the data, neither can
yours, and your application won't be real useful, eh?
[+} It was rumored at some point that Apache 2 would allow PHP Modules to
be run as different users in different VirtualHosts. A recent post by
Rasmus makes me think that never happened. But maybe it did. RTFM. If
you *can* set up your server that way, and make each VirtualHost run PHP
Module as a different user, then you can limit access in Apache 2 in a
better way.
You can add a *tiny* bit of a barrier by burying the stuff PHP can
read/write *outside* the web tree, and only display things on your server
using PHP to 'filter' the content.
For example, if you allow JPEGs to be uploaded, set up your PHP
readable/writeable directory in, say, ~/image instead of
~/public_html/images
Then you need a PHP script to 'display' the JPEG:
?php
/* display.php */
if (!isset($_SERVER['PATH_INFO'])){
trigger_error(Invalid attempt to use display.php without specifying
image filename, possibly for nefarious reasons., E_USER_ERROR);
exit;
}
$filename = $_SERVER['PATH_INFO'];
$filename = preg_replace('/[A-Za-z0-9_\\.-]/', '', $filename);
if ($filename != $_SERVER['PATH_INFO']){
trigger_error(Invalid character in image filename, possibly for
nefarious reasons., E_USER_ERROR);
exit;
}
readfile(/full/path/to/your/home/images/$filenaem);
?
You can even bury it *inside* a directory that the PHP user can *NOT*
read, so the Bad Guy has to guess at the name of the directory that they
can read, because it's inside a directory that they can't read:
mkdir access
chmod 600 access
mkdir access/images
chmod 700 access/images
chown apache access/images
So now the 'apache' user (may be 'nobody' or 'www' or ... on your system)
can do what it wants with the images directory, but somebody poking around
in your system won't *KNOW* there is an images directory, cuz they can't
read 'access' directory to find out it's there.
You then change the PHP display.php script to run some basic sanity checks
before presenting any JPEG to the browser.
You can, fairly easily:
Be sure that http://php.net/getimagesize 'works' on the JPEG, so it's
probably a JPEG and not some kind of Trojan/Virus/Whatever.
Only serve up images that were recorded through your application in the
database as having been uploaded. So if somebody manages to put a JPEG in
your directory, they'd *also* have to hack into your MySQL data to add it
to the database.
Record an http://php.net/md5 hash of the file when it was uploaded, so if
somebody changes the file out from under you, you can do md5() again and
see that it was changed.
If all these security measures are insufficient for your application, then
it's time to buy a dedicated server, where there aren't any other PHP
users other than yourself [*] and then this is all moot.
[*] Of course, on a dedicated server, if a hacker breaks in, they can
probably run PHP and do these Bad Things but if they've already broken
in, you've got MUCH BIGGER PROBLEMS than your PHP-alterable data.
For *MOST* web applications, the measures outline here (or similar) are
sufficient, so you can make PHP secure enough to manage your risk to an
acceptable level on a shared server.
In some cases, you simply can't, and you need a dedicated server -- But
that's usually something you know you need anyway, for all the *OTHER*
security issues involved in the first place.
PS The ideas above are but a fraction of the kinds of things one can do to
limit access and sanity check content using PHP.

[PHP] Re: Get name of extending class with static method call
__CLASS__ contains the name of the class the method is in. In my sample it
would be 'Car' and not 'Porsche'.
What I don't understand is why the behaviour of debug_backtrace() has been
changed!?!
Regards, Torsten
I have no idea why the behaviour changed (I didn't really use the
function before, either). And I see now the change in the manual that
addresses this (essentially debug_backtrace gives you __CLASS__)
If you had an actual instance of the class you could use get_class, but
alas you are using a static method call. You punk.
The only other solution that comes to mind is a little messy but it lets
you get away with no object. Instead of calling the method statically
you can use call_user_func_array() with the child class name as a
parameter. Then change the parent method to accept the child class name
as a parameter.
?php
function call_static_child() {
$drive_args = func_get_args();
/** assume that first parameter is child of class Car */
return call_user_func_array(array($drive_args[0], 'drive'), $drive_args);
}

[PHP] dba_open(), NFS file locking test please
If you have php installed with the dba extension, and have access to NFS,
could you try out the code below, to see if it works for you.
Doesn't matter what OS you're using (as long as the OS professes its capable
of locking over NFS).
Im currently using FreeBSD 5.3 (server client), with NFS the lockd
daemon running.
Dummy code -
?php
var_dump(dba_open('/path/to/nfs_mount/foo.dat', 'c', 'gdbm'));die;
?
Gives me -

It creates the file, but Im guessing that its unable to get a lock on it.

Chris, I was thinking of this as well. Except that the method drive is
actually a static method so the class definition for Car is (I'm
assuming) more like this:
?php
class Car {
static function drive() {
/** I am a static function, so $this should not exist! */
/** However, class constants and static variables are available */
}
}
class Porsche extends Car { }
Porsche::drive();

Stephen,
Not sure I can see your error either but here's a thought that might be
useful. I run Apache 2.0 on my laptop with PHP 4.3.4. Sessions work fine
for me. For various reasons I chose to set my session.save_path at the
beginning of every script and it works fine. Here's the line of code I use:
session_save_path('c:\Program Files\Apache Group\Apache2\htdocs\tmp');
Again it doesn't answer the question you're asking but it might be
an approach that's easy for you to implement. I do it via an include().

Stephen,
Not sure I can see your error either but here's a thought that might be
useful. I run Apache 2.0 on my laptop with PHP 4.3.4. Sessions work fine
for me. For various reasons I chose to set my session.save_path at the
beginning of every script and it works fine. Here's the line of code I use:
session_save_path('c:\Program Files\Apache Group\Apache2\htdocs\tmp');
Again it doesn't answer the question you're asking but it might be
an approach that's easy for you to implement. I do it via an include().

[PHP] weird upload problem
Hi,

works, except two problems.
1) for some odd reason if i attach all fields with an image it only submits
5. seems its skipping one.
2) if i attach an image to field 1, 3, 5 and skip the other fields only 1
file gets uploaded.. how do i make it so it doesnt matter which fields are
used? just submit whatever fields(s) are used.. i snipped a lot of the code
off the script so its easier to find the problem.. maybe i just overlooked
something.
form action=/ enctype=multipart/form-data method=post
1: input type=file name=image[]br /
2: input type=file name=image[]br /
3: input type=file name=image[]br /
4: input type=file name=image[]br /
5: input type=file name=image[]br /

Re: [PHP] Re: Get name of extending class with static method call
I was kinda thinking about all that too, for a project I'm currently
doing, in that I wanted to be able to create a singleton, without
having to put the singleton code in each class. The only hack I could
think of was to use debug_backtrace() to get the line of source that
contained the call, and parse(reparse) it manually.
Bare in mind that this is EXTREMELY UGLY, and probably extremely slow,
and unprofessional, but as a wise man once said(Andrew Morton IIRC),
if there is no implemention there is nothing to improve on, but if you
provide a crappy solution, you can rally people to improve on it.
If you're new to PHP, or prone to picking up bad habits, stop reading now.
eg
?pseudo_code
class Base {
function static_get_class_name(){
list($file, $line, $method) =
get_calling_file_and_line_and_method_from_debug_backtrace();
$codeline = file($file)[$line];
preg_match(/([a-zA-Z_][a-zA-Z0-9_]*)::$method_name/, $codeline, $match);
return $match[1];
}

Steve My laptop is my development server but my production work is
on a public server. I apologize for not giving you a complete
description of what I do ... I set my session.save_path on the public
server by creating a TMP directory in my Public_html folder. I've
created an IF THEN ELSE that recognizes whether the code is being
executed on my laptop or at the public server. The entire include() file
is as follows:
?php
if ($_SERVER['SERVER_NAME'] == localhost)
{
session_save_path('c:\Program Files\Apache Group\Apache2\htdocs\tmp');
} else {
session_save_path('/...x/public_html/tmp');
}
?
Works great ... and the old session files in the public_html/tmp
directory get cleaned out automatically.

should give you a more complete answer .. Jerry

Re: [PHP] Forms on PHP
Leon Poon wrote:
Refer to the following line numbers:
01 ?php

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
$_POST['form_sumbitted'], thus once again the 'form hass been submitted'
message.
In order to prevent this from happening, you should do a header('Location:
success-page.php') on a successful submit. This is so that at the redirected
page, the user would not have resent data even if he press the Reload
button.
Hope this helps
-Leon
Many thanks - at the top of the file I put in the code:
if ($_POST['submit'])
header('Location: .../submitted.php');
where further down in the form I have name=submit for the submit button.
This goes to a new page submitted.php. The code is in fact now at
http://proteus.as.arizona.edu/~csharp/lightcurved.php .
No doubt there is still a way of writing back to the original page after
the submit button has been clicked, but I can't see an easy way, so this
will have to do for now. A work-around is to do it in frames, and write
to a frame at the bottom so that it appears to be in the same page.

Here are the files created by make install: Installing PHP SAPI module: cgi Installing PHP CGI into: /usr/bin/ Installing shared extensions: /usr/lib/php4/extensions/no-debug-non-zts-20020429/ Installing PEAR environment: /usr/lib/php4/php/ [PEAR] Archive_Tar- already installed: 1.2 [PEAR] Console_Getopt - already installed: 1.2 [PEAR] PEAR - already installed: 1.3.2 Wrote PEAR system config file at: /usr/etc/pear.conf You may want to add: /usr/lib/php4/php to your php.ini include_path [PEAR] DB - already installed: 1.6.8 [PEAR] HTTP - already installed: 1.3.3 [PEAR] Mail - already installed: 1.1.4 [PEAR] Net_SMTP - already installed: 1.2.6 [PEAR] Net_Socket - already installed: 1.0.2 [PEAR] XML_Parser - already installed: 1.2.1 [PEAR] XML_RPC- already installed: 1.1.0 Installing build environment: /usr/lib/php/build/ Installing header files: /usr/include/php/ Installing helper programs: /usr/bin/ program: phpize program: php-config program: phpextdist I get no errors in the make/make test/make install stages. Why isn't libphp4.so created? It also seems bizarre that I am the only person that has encountered this. Thanks. __ Do you Yahoo!? Yahoo! Mail - now with 250MB free storage.
