I have a form where I am dynamically building a bunch of checkbox
inputs. Then when submitted, I need to update the db. Problem is, of
course, if the checkbox is unchecked then the $_POST doesn't have the
value in the array. How can I get the value from $_POST even though
it's unchecked?
For example, here would be the generated form:
input type=checkbox name=cars[2] value=1Car 1
input type=checkbox name=cars[3] value=1Car 2
input type=checkbox name=cars[4] value=1Car 3
input type=checkbox name=cars[5] value=1Car 4
Then in the update I loop through:
foreach($_POST[cars] as $id=$value){
//update vehicles set value to yes or no
}
But, if the unchecked values aren't in $_POST, how do I know to update them???
Thanks!

Well if your keys are a straight sequence of numbers instead of a foreach
you can do a for loop and for those whose value is not one, set to zero.

This is a good example on how *not* to trust data via form data
posted. I'm assuming you have some sort of one to many relation
going on:
table lot {
id int,
lot varchar(255) -- Lot 1
}
table vehicles {
id int,
name varchar(255) -- Car 1, Car 2, etc...
}
table lotvehicle {
lot_id int,
vehicle_id int,
}
The form value of cars[X] where X being the id of vehicle and the
value of 1 being it is selected (although with the form definition
you just want to know if if cars[X] is defined.).
So we have a form that will eventually need to knnow what values
should be selected. Potentially data alreadly exists that may have
the same records. There are two options (or perhaps more) to
approach this:
Decide as we go approach and clean up:

Ciprian Constantinescu wrote: Not efficient, because the actual size on the disk depends on the filesystem. I don't think you can find out before writing it to the disk excuse me but: 1. the OP asked for the size of the file, not the number of bytes it takes up on disk (which are eaten up in fixed increments aka clusters) - then again chances are the OP didn't consider that there may be a difference, so he'll have to figure out which of the 2 number is actually important to him. 2. you don't seem to know what 'efficient' means, generating a wrong (in your opinion) size consitutes wrongness not inefficiency. I called it inefficient because it requires that the whole file is read into php's memoryspace. Jochem Maas [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Karuna wrote: Hi.

[PHP] FW: Merging two images (GD PNG)
I have two images which I want to overlay on each other. Image1 is a satellite image. Image2 is contains the statistical data we collected. It has a transparent background and should be overlaid on top of the satellite image. Both are in PNG format. My current code: ? $dataImage = imagecreate(1000, 1000); $dIBack = imagecolorallocate($dataImage, 199, 199, 199); imagecolortransparent($dataImage, $dIBack); $darkGreen= imagecolorallocate($tileImage, 2, 123, 48 ); $grey = imagecolorallocate($tileImage, 118, 131, 120); $fuchsia = imagecolorallocate($tileImage, 255, 0, 255); $aqua = imagecolorallocate($tileImage, 113, 168, 194); $brown= imagecolorallocate($tileImage, 177, 170, 107); $offwhite = imagecolorallocate($tileImage, 187, 210, 193); $black= imagecolorallocate($tileImage, 0, 0, 0 ); $blue = imagecolorallocate($tileImage, 0, 0, 255); $red = imagecolorallocate($tileImage, 255, 0, 0 ); $yellow = imagecolorallocate($tileImage, 255, 255, 0 ); /* Code to draw data on image comes here */ $satImage = imagecreatefrompng(sat_image.png); $mergedImage = imagecreate(1000, 1000); imagealphablending($mergedImage, true); imagecopy($mergedImage, $satImage, 0, 0, 0, 0, 1000, 1000); imagecopy($mergedImage, $dataImage, 0, 0, 0, 0, 1000, 1000); imagepng($mergedImage, merged_image.png); imagedestroy($mergedImage); imagedestroy($satImage); imagedestroy($dataImage); ? Notes: 1. When using imagecreatetruecolor the images turn black 2. When using imagealphablending = true or imagealphablending = false with imagecopy the result is the same. The top image is shown but it is almost transparent. Some images are also discoloured. 3. When using imagecopymerge to copy with a pct value of 99, and commenting out the imagealphablending line the top image does not appear at all 4. When using imagecopymerge to copy with a pct value of 99, and imagealphablending=true, it has the same result as 2. above. 5. When using imagecopymerge to copy with a pct value of 50, and Imagealphablending=true, it has the same result as 2. above. What is the effect of the pct value of imagecopymerge? Should I be using different values for the pct value of imagecopymerge or is there an alternative method which will do what I want to be done? It seems to me that the palette used in the top image is not merged with the palette used in the satellite image. Albert -- No virus found in this outgoing message. Checked by AVG Free Edition.

Re: [PHP] checkboxes
Excellent response. You should always be expecting certain data. So if no checkboxes are checked, your code should realize that since it was expecting the data and none was submitted. The lazy way is much easier to code, but it is actually fairly efficient. You are only hitting the database twice, once of the delete and once for the bulk insert. On a fixed record length table, the lazy way may actually be quicker.

[PHP] PHP on Mobile Devices(Pocket PC specifically)
Does anybody know of a way to run PHP files on a windows mobile device(Pocket PC 2003)? Optimally I'd like to run it under a web server running on the mobile device itself but barring that I'll take some form of command line I guess. Realize that the mobile device will NOT be running any active network connectivity. For all intents and purposes the individual is sitting in a wireless empty room with no land connectivity talking to the mobile device. I haven't been able to find any web servers that run on the Pocket PC that can be viewed by the mobile IE(or mobile Opera either I guess) when it doesn't have active connectivity, at which point I might as well just be using a server for all of the mobile devices rather than hiding it on the mobile device.

It sounds like you have a PHP script with a security vulnerability, and you think that restricting what the client uses to request the script is going to fix it. This is not a good approach.

[PHP] Lowest PHP version to work with MySQL 4.1.x

Re: [PHP] Schroedinger's Bug - may require exorcism...
What to do next? I'd check to see if your page is being inadvertantly called
twice (I've seen this happen when people used frames.. or like someone else
mentioned, doing a double include() or sometimes redirecting back to itself via
header())... anything that could possibly re-initiate the page, check into.
Failing that, do it old school... just inserted die() statements to break
execution at various points and see where the probably first starts occuring
and focus in that area. Crude but it works. At least helps narrow down where
the problem could be.
It doesn't do something silly like include() itself inside a conditional
somewhere does it?
You might also echo/var_dump/print_r/whatever some of your key variables
(especially input variables like $_GET/$_POST/etc and variables used in
conditionals) and try to isolate what combination causes your problem. Since
it doesn't do it all the time, I'd guess you could have something like:
$x = 4;
if ($x 1) {
include('someinclude.inc');
}
if ($x 5) {
include('someinclude.inc');
}
Where 'someinclude.inc' contains your double declarations.
Next point... check your logic around your include()/require()s and such.
Maybe you have a condition where something is falling into multiple categories.
The logic puzzle is as much about writing good logic as untangling possibly
flawed logic.
If all else fails, trace through your code by hand... interpret it in your head
like the computer would.. like by line.. maybe you'll see where something is
ambiguous and under certain conditions creates a fail.
Let us know what you find.. kind of curious myself.
-TG
= = = Original message = = =
So... I have this script (being called in a perfectly typical way by
PHP 4.4.1 through mod_php in Apache 2.0.55) which sometimes runs
perfectly, and sometimes chooses, totally haphazardly, to seemingly
run itself twice, which of course causes it to die with a fatal error
after it tries to redefine some functions.
As mysterious as that is, it turns out it must be something
altogether more sinister. I tried putting die() at the end of the
script, on the assumption that it was for some reason executing
twice, yet behold: the problem is still present, and the PHP error
log still complains about constants and functions being redefined!
The problem, I therefore thought, cannot be that the script is being
run twice. (In retrospect, this was the most likely possibility,
because the page doesn't actually output anything if it dies with
this error.) So for debugging, I added a bit that logs one message to
a file immediately before the die() at the end of the file, and a
different message after the die(). The die() seems to be working
normally, in that it only logs the first message...
But wait a second! WTF? If the PHP error log is to be believed, then
the script should be dying with a fatal error before it even *gets*
to that point in the script, isn't it?
And the greater WTF is the fact that, as I mentioned above, every
time the page is requested, it unpredictably either does this or
works flawlessly. Oh my. How do I even *begin* to debug something
like this?
Thanks for any help.

Re: [PHP] php related segmentation fault with Apache 2.0.55
Hi again,
I tried compiling and installing php 4.4.1 with Apache 2.0.54, out of
curiosity (because php 4.3.10 and Apache 2.0.54 didn't give me any
problems).
With this combination, I still get a segmentation fault with at least
one php script. The gdb backtrace is:

I think it is worth reiterating that this is only happening with one
script, to our knowledge. The actual file being served is a .shtml
file which includes a php script. I looked at the php script, and it
looks like a pretty straightforward database access script, using
mysql. Is there anything I should look for in that script?
Thanks,

[PHP] include_once behaves differently in mod_php4 vs php5-cgi
Hello!
There's a website with a following structure
index.php in the site's DocumentRoot directory (for this thread, let's
call it /www)
functions.php, init.php and db_connect.php in /www/library
index.php includes line:
include_once('library/functions.php');
functions.php includes lines:
include_once('db_connect.php');
include_once('init.php');
The website was running fine under PHP 4.4.0 installed as Apache module.
Then we tried it with PHP 5.0.5 installed as CGI. We got the following
errors:
PHP Warning: main() : open_basedir restriction in effect.
File(/db_connect.php) is not within the allowed path(s):
(/www:/usr/local/www/phpMyAdmin:/var/tmp/php) in
/www/library/functions.php on line 2
PHP Warning: main(db_connect.php) : failed to open stream: Operation
not permitted in /www/library/functions.php on line 2
PHP Warning: main() : Failed opening 'db_connect.php' for inclusion
(include_path='.:') in /www/library/functions.php on line 2
...and similar 3 messages about init.php.
Note that first warning is about '/db_connect.php', not 'db_connect.php'
or './db_connect.php'. /www/library should be inside the open_basedir,
since it is under /www, which is listed in open_basedir in php.ini. It
looks like something is changed in PHP's behaviour between versions 4
and 5 or is differently handled in CGI vs Apache SAPI, but I find it
unlikely since I can find no documentation regarding this. It's more
likely that I am overlooking something trivial, but I can't figure out
what it is.
I tried to change the include lines to
include_once('./db_connect.php');
include_once('./init.php');
but this made no difference.
However, when I specify the full path:
include_once('/www/library/db_connect.php');
include_once('/www/library/init.php');
then the errors disappear and 'everything' seems to work.
Also, I never get any errors about the
include_once('library/funcions.php');
line in index.php
I'm puzzled...

[PHP] RE: help avoid multiple login
-Mensagem original-
De: Jochem Maas [mailto:[EMAIL PROTECTED]
the normal way of doing session 'closing' is by way of 'garbage
collection'
- every now and then a script/process/function is run that 'closes' any
sessions which are (according to your criteria) inactive. php has stuff
built it that will do this for you to a degree.
-
Is there a way I can access sessions from other users on a script?
what exactly do you mean by that last sentence? I don't quite follow it.
--
I mean if I knew all active session id's I could compare them to the
members_online table.
An example in pseudo code:
// Member logs in, store session id, login datetime, last visit datetime:
INSERT INTO members_online
// Get active session ids from table:
php code
// Compare active session ids with table sessions:
for ($i=0; $i table rows; $i++){
if ( !isset( session id from member $i )) {
DELETE member from table
}
}
If yes I could store the session id on a table and later check if isset.
You could write the session id into a table when the session is started,
along with the start time.
Something like
sessionid CHAR|starttime DATETIME|lastvisittime DATETIME
You could then update this table each time the user visits a page, and
delete it if the interval between starttime and lastvisittime is longer
than
you want. A cron job/scheduled task could be used to clean this table up
periodically
a nice description of 'session garbage collection' :-)
which is pretty much all you can do in terms of 'logoff'.
I already use a class to perform this task. The problem is if a member
closes the browser windows and then tries to login again before the
specified timeout.
Does Apache have a function like asp Session_OnStart, Session_OnEnd ?
I am using IIS and PHP 5.0.4
Thanks in advance.

This might be good enough:

You could also replace:
if (!preg_match('/([0-9]*)(\\.0*)?/', $_POST['x'])
with:
if(!is_numeric($_POST['x']) || $_POST['x'] 0)
This would ensure that your value only contains numbers, and that it is
greater than zero. Then when you put it into the $_CLEAN array, you can
type-cast it as an int (as in the other script) and that would convert
any doubles to an integer value. If you wanted you could also round,
ceil, or floor the value.

[PHP] Using POST to pass variables
When I have more than one button on a page, I us what I call a reentrant
approach. That is the page calls itself.
If the page is emailer.pgp, the the FORM tag would be
form method=get action=emailer.php
At the top is
?php
$send= $_GET[btnSend]; // Send button pressed
$cancel = $_GET[btnCancel];// Cancel is pressed
$message = $_GET[message];
if ($send) {
header(location: send.php?message= . $message);
}
if ($cancel) {
header(location: index.php);
}
?
Is there a better way to do this so I can use a POST form?
Thank you...

Except this passes the message in the URL. Is there a way to pass
variables as a POST (not in the URL)?
I have a class that creates a new socket, however on my client's shared
server, the creation of sockets is not allowed. With a new socket, I am
able to pass the variable information via the socket (POST).

[PHP] Database Class Help
Hi,
We have a database class that we want to use to connect to multiple
databases at the same time using different variables.
Here is part of the db class:
class db {
var $dbh = ;
var $q = ;
function db($db_host, $db_user, $db_pass, $db_name) {
$this-dbh = @mysql_pconnect($db_host, $db_user, $db_pass);
$this-select_db($db_name);
}
function select_db($db) {
if ([EMAIL PROTECTED]($db, $this-dbh)) {
die(emCannot select database because:/em/p\npcode .
mysql_error() . /code);
}
}
function num_rows($_q) {
if (!$this-q = mysql_query($_q, $this-dbh)) {
die(Invalid query \code . $_q . /code\/p\npcode .
mysql_error() . /code);
} else {
return mysql_num_rows($this-q);
}
@mysql_free_result($this-q);
}
}
In my php file I say something like
?php
Include ( 'db.php' );
$db_1 = new db('server','username','password','db1');
$db_2 = new db('server','username','password','db2');
Echo $db_1-num_rows('select * from table1');
Echo $db_2-num_rows('select * from table2');
?
Now that happens is when I try and do the query for db1, I get told that
db2.table1 doesn't exist. I can swop anything around and it doesn't seem to
work for one of the classes.
Does anyone have any idea as to why this is happening?
Thanks a lot,
Ian

You didn't specify but I guess all your databases are on the same server.
When accessing multiple databases on the same server using multiple
instances of a class, you need to make multiple connections to the server.
By default PHP creates only ONE connection to a server and the database you
select is linked to the connection. So instantiating another instance will
use the previous established connection and change the database.
To force a new connection, you need to use mysql_connect() instead of
mysql_pconnect(). When using mysql_connect() you can specify:
$this-dbh = @mysql_connect($db_host, $db_user, $db_pass, true);
[quote from=PHP manual]
resource mysql_connect ( [string server [, string username [, string
password [, bool new_link [, int client_flags ] )
[/quote]
Which will force a new connection. By default PHP will use a connection
which have already been established.
Take care when doing this as each time you instantiate a class a new
connection to the database will be created adding additional load on your
database which can cause a denial of service.
I normally store a list of connections to servers and databases in a
variable which can be accessed by the script. Every time I instantiate a new
instance of my database class I first make sure that a connection to that
server and database does not already exist. If it does exist then I call
mysql_connect() without the true for new_link otherwise I call
mysql_connect() with the true for new_link.
The downside of this is that you do not have persistent connections which
last beyond the end of the script.
Hope it helps
