First question is why do you need to pass it through like that?
> it is not coming across as an array so the foreach is throwing an error
I assume it always has a ',' in it if you only choose one box.
if (strpos($_POST['selectedcontactlist'], ',') === false) {
// no boxes were selected - or at least there is no comma.
die();
}
// turn it into an array
$selected_contact_lists = explode(',', $_POST['selectedcontactlist']);
> This number are selected in a checkbox and passed with a javascript to
> the script should I be converting them to an array in the javascript.
No need to do that either, just make the form variable an array:
The [] turns it into an array which php can then process automatically
as an array.
You can check that some checkboxes are ticked using an idea similar to this:
http://homepage.ntlworld.com/kayseycarvey/jss3p8.html
Though I'd just either set a flag or counter instead of a message when
you find one that is checked.
If you're just checking that any are checked, as soon as you find one,
return true out of the function.

Re: [PHP] tracking Mials Which were bounced.
Seems like the general way is to create a mailbox (POP3 or IMAP) to accept the bounces, then check it periodically and mark the emails as invalid in your local database. I would set threshholds so you don't mark something failed that only bounced once - it could have been a mail setup error or something else; I'd say wait for 3 failures in a 7 day period at least. If you get 3 bounces by that point, the address is probably safely dead. You can use PHP's IMAP functions to check the mailbox (even for POP3) or a million classes or your own functions directly on the socket (POP3 is a simple protocol) - it also helps if you parse the bounced email message to process the return address and the mail code; perhaps build something better than just 3 failures = invalid, but actually determine if they're full out failures, or if they're just temporary bounces, etc. Another method: you could just parse mail logs, if you have access to them. > Chetan Rane wrote: > > Hi All > > > > I am using a PHP Mailer to send mass mails. > > How can I Identify how mails have bounced. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] calling rsync from php script
Hello,
I have a bash script update.sh that contains:
rsync -- delete -avz -e ssh ${files} [EMAIL PROTECTED]:/red
when I use that script ./update.sh as root, it works like a charm as I set up
the private/public key properly.
When run from a php script through the apache webserver
The rsync line is ignored.
I understand that the php script is called under the apache user, when the
private/public key is for my root user. How can I set the the keys so that the
apache user can run fully the php script?
More generally, how do php users handles the ssh private/public keys when
calling rsync?
Thank you

There's so many things that are out of your control when you include a third-party script that could stop it loading; misconfigured servers on their end, network outages, corporate firewalls blocking their server, etc. You can't stop any of that.

Re: [PHP] convert query result to array

As Wang suggested, we should write our own function.
its easy... i have done so many times for larger database.
Store earch rows of the resultset in the array (multidimensional ie. 2). and
then work on the array using the loops & conditions
$query = "select * from tablename";
$result = mysql_query($query);
while($arr = somefunction($result)){
$resultarray[] = $arr;
}
Hope it works!

Re: [PHP] Permissions set on php script question
If your web-server is setup to read files with .php extension through PHP engine (it is I guess) than no body from outside (using HTTP) can't read content of original PHP file only the output of that particular script.

You could use a combination of BASh and Expect shell code here,
but it wouldn't be very secure, because that would automate the root

Generate keys for `nobody` or `apache` (whatever user as which
Apache is being executed). Alternatively, install phpSuExec, Suhosin,
or suPHP so that the scripts are run as the user for which they were
called.

PHP is sevrer sided. So if you want to check if a user provided the
textarea with input. You have to submit the page. and let PHP do the magic.
If the textarea is not filled. You could send the user back to the form.
With an apropriat warning message.
It's probably easier to do it with client side javascript.
Check the contents of the textarea on submit and preform some actions
from there.

One thing you might consider is, first of all, there are many characters which do not print and spaces are one of them, but from a computer standpoint they are characters, tabs and new lines are some others, the list goes on. For this specific case you can trim the results and that often will eliminate most of these if they appear at either end of what was typed, in this case the entire thing.

You should not rely on register_globals, and use either $_GET or $_POST
instead depending on which methoed to send your form details back to the
server. Eg:

You can use the trim() function to determine whether a variable is just
whitespace.
$comments = trim($_POST['comments']);
if ($comments == '') {
// Show error message

[PHP] Can Safari 3 be forced to cache a large jpeg with PHP headers?
I am creating a touch-screen kiosk application, using a full-screen version of Safari 3.1, and was wondering if there's a way I can force Safari to cache a large background image JPEG. What I'm finding is that Safari 3 will sometimes cache my large 1.1 MB background image (1680x1050), and display perfectly fine, but on occassion Safari 3 will "think about the cache" and Flash the screen white for a millisecond and then draw the screen. Firefox doesn't seem to have this problem, so unfortunately this is a Safari 3 only issue. I really only want to cache this ONE image - - - nothing else.

Re: [PHP] Why doesn't working with array's ever stick in my thick head?
Hi Everyone,
I am taking another stab at this problem, complete with code and an

Here is the issue:
I need to be able to display pounds and ounces of a given number of

what I can't seem to get through my head is how to do it for a

Weight of a single piece:size="5" value="{$PieceWeight}">

while ($c != $num) {
echo << Route Number:value="{$RouteNumber}"> Number of pieces: name="txtRoutePieces" value="{$RoutePieces}"size="5">Total

$c++;
}
echo "";
//DEBUG
dump_debug($RoutePieces);

Well, chop() is an alias of rtrim(), so it won't work here for, say,
trimming control characters at the end of the string like line feeds.
trim() is actually the best bit here.

There is always using substr to mimic the Perl chomp() function. Look thru

Actually trim() is probably less efficient since both ends of the string
will be examined whereas a string containing entirely whitespace
characters will rtrim() (chop() if you will) to an empty string also but
the second side won't need to be examined (even if only to check for 0
length).
But maybe you didn't realize this because your assertion was wrong in
the first place:
> so it won't work here for, say, trimming control characters at the
> end of the string like line feeds.
When clearly looking at the online documentation for rtrim() we see:
This function returns a string with whitespace stripped from
the end of str .
Without the second parameter, rtrim() will strip these characters:
" "(ASCII 32 (0x20)), an ordinary space.
"\t" (ASCII 9 (0x09)), a tab.
"\n" (ASCII 10 (0x0A)), a new line (line feed).
"\r" (ASCII 13 (0x0D)), a carriage return.
"\0" (ASCII 0 (0x00)), the NUL-byte.
"\x0B" (ASCII 11 (0x0B)), a vertical tab.
Cheers,
Rob.

DOM is a successor to DOMXML from php4. its a bulky, yet powerful interface into the DOM. SimpleXML is also a DOM parser, however the interface is simpler in exchange for less power. the good news is in php5 you can switch back and for between DOM and SimpleXML easily at virtually no cost. my modo in php5 is to use SimpleXML unless there is a real need for DOM, and in that case most likey, you can get away w/ converting to DOM at runtime (again very little cost there) and doing a few operations, then carrying on w/ SimpleXML. -nathan

I suspect that you are giving a very short timeout but then you are not
handling the timeout error properly.
Anyway, before reinventing the wheel, you may to try this HTTP client
class that supports many options including establishing SSL corrections
and setting and handling timeouts correctly.

[PHP] validating using php
thanks to everyone for providing the solution for validating textarea using
php i have used the following and it worked
$add = trim($_POST["add"]);
if(strlen(trim($add)) == 0 )
{
$error.="Please enter your address ";
}
as part of the form the user has to fill in their name, assuming if the user
simply presses the space bar i would like to display a message like the text
area. presently my validation for name is
$name = trim($_POST["name"]);
if( strlen(trim($name) == 0 ) || !preg_match('/^[a-zA-Z ]+$/x', $name) )
{
$error.="Name is blank or has special characters ";
}
with the above code for validating the name if a user types only spaces then
the error message is displayed however if there is a gap in the name example
john smith the error message is appearing which should not be happening as i
have given
preg_match('/^[a-zA-Z ]+$/x', $name) which means the user can type small,
upper case letters and also there can be a space in the name
how can i change the php code = if( strlen(trim($name) == 0 ) ||
!preg_match('/^[a-zA-Z ]+$/x', $name) )
so that i can validate both a) blank spaces and also accept spaces between
the name, i can validate individually for spaces and uses preg_match as 2
separate lines, instead i would like to validate in a single line of php
please advice.
thanks.
[PHP] form validation using php
hi
i need to validate a field in a form where a user enters their lodgement
number as part of a registration form. this lodgement number can have
letters, numbers, spaces and special characters. i do not know exactly what
those special characters are, so do i have to define the type of special
characters and validate accordingly.
presently my php code for validating the lodgement number is
$lodgementtf = $_POST["lodgementtf"];
if($lodgementtf == "" || !preg_match("/^[a-zA-Z0-9_ <]+$/", $lodgementtf) )
{
echo "display error message":
}
i also have another way of validating
if($lodgementnumber == "" || !preg_match("/^[a-zA-Z0-9_ [EMAIL
PROTECTED]&*()]+$/",
$lodgementnumber) )
does this mean that the special characters can only be = a space AND
[EMAIL PROTECTED]&*() and no other special characters.
please advice.
thanks.
