I have built an application similar to yours, and I have solved the printing problem by using software from the following two companies: http://www.nicelabel.com and http://www.namtuk.com/autoprintemail.aspx Basically the user runs a web page which generates the required report, in either XML or PDF format (I believe others are available) and sends an email which identifies a particular client printer. At the client end, with any number of PCs and printers, there is a piece of software running which looks for these emails, and when one is received it sends the print to the designated printer. Each report can be tailored to output to any printer, including a specific printer for each user. This means that the user does not see the generated report in his web browser and then have to press the PRINT key and choose the printer before it gets printed. He simply presses a Generate Report button, and within a few seconds it is sent to the printer.

thanks! 2009/1/21 Manuel Lemos mle...@acm.org Hello, on 01/20/2009 09:10 PM Matthias Laug said the following: I've got a problem using curl to upload a file. I want to send it to a form written with the Django Framework. Post Request are processed correctly, with one anomaly. This piece of code works fine curl_setopt($process, CURLOPT_POSTFIELDS, http_build_query($data)); But if i provide only an array no data is send to the form curl_setopt($process, CURLOPT_POSTFIELDS, $data); I have read somewhere that curl sends formdata with enctype=form/mulitpart only if I provide an array not a string. If I add @filename to the $data variable (string or array) it does not send the file to the form. Each example I have found in the internet so far did not work. I do not use the Curl functions directly. When possible I use fsockopen as alternative and use this HTTP client class to submit any kind of HTTP requests. Take a look at the test_http_post.php to see how simple is to submit form with one or more file uploads. http://www.phpclasses.org/httpclient -- Regards, Manuel Lemos Find and post PHP jobs http://www.phpclasses.org/jobs/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- Matthias Laug Schillerstr. 36 10627 Berlin http://www.mconcepts-online.com/

$Today = date('m/d/y');
$Agreements = 0;
$lateFees = 0;

[PHP] About printing functions
Hi gang,
Lets say that you have a function that prints something to the
output simply like this:
function print_str() {
print blah blah blah;
}
I was wondering if there is a way to use this output and store it in a
var or something without changing the function itself?
And store the blah blah blah somewhere for later use?
I can think of many reasons that someone could use this.

[PHP] Suggested diagramming package for php application
Hi - we currently use visio for creating basic block diagrams and save these as images to our web site so others can view them. What we really would like to do is to have our php application be able to display the diagram and then upon clicking an edit button, allow the user to edit the diagram directly. We are currently using php 5 and postgresql 8.2 on an Ubuntu server. I was wondering if anyone had any suggestions on an open source package that would allow us to do this functionality?

A couple of thoughts. First precede all your mysql_* calls with the at
sign (@) to shut up the routines if they generate text. I had this
problem, and that was the answer.
Second, store your connection resource as a class variable, so you can
pass it around to the various routines. Actually, you're already doing
this, but I prefer to do so explicitly, as:
var $link;
at the top of the class.
I have a similar class for PostgreSQL. I also have routines like
update, which allow you to pass a table name and an associative array
of field values. Same thing for an insert routine.

The only way to save this text off is to put it in a $_SESSION variable

you could also store it in a database.

I'd try to move to using the mysqli functions or class, which
you can still wrap in a custom object (I do this because
I like to minimize the interface to the bare, bare minimum ...
professional laziness you might say).
does you class need to be php4 compatible? I'd hope
not but you may still have to support php4 ... even then

yes that's very bad advice. using error suppression is bad for performance
and debugging, don't do it unless you really really have to (e.g. you
have some function that spits warnings even with display_errors set to Off)
display_errors should be set to Off in production, and errors/warnings shouldn't
be suppressed, they should be logged.

wouldn't the slickest way be to carry/store unixtimestamps and
then output whatever version you need when you need it,
the conversion back and forth *seems* pointless.

$t = strftime('%R', strtotime($t));
return $t;
what's with the superfluous variable?
why not just:
return strftime('%R', strtotime($t));
also, small point, if you came across the function
militaryToStandard() somewhere in the code, how would
one know if it were all about about time formats
or elephants?

One of the goals of encapsulating DB access should be to hide some of the
tediousness of database access, however, using the interface for your object
you're still writing just as many (if not more) lines of code as you would by
simply using the mysql_* functions directly.
As an example of how you can put this into practice, here's the interface to
the DB object that I use:
The object is implemented as a singleton. When retrieved initially the
constructor deals with setting up the connection using constant defined in the
class for username, password, dbName and server address. The instance itself
wraps a PDO connection and provides the following interface:
// Query functions
query($query, $queryName = null, $taskName = null);
prepare($query, $queryName, $taskName = null);
execute($queryName, array $params = array(), $taskName = null);
static sanitize($string);
// Data retrieval functions
getResults($queryName, $taskName = null);
getColumn($queryName, $taskName = null, $columnIndex = 0);
getRow($queryName, $taskName = null, $rowIndex = 0);
getCell($queryName, $taskName = null, $rowIndex = 0, $columnIndex = 0);
// Storage control
reset($queryName, $taskName = null);
resetAll($taskName = null);
The interface is clean and lets me handle most common cases with readable
code:
// Retrieve one piece of data from the database
try {
$db = DB::getInstance();
$db-prepare('SELECT COUNT(*) FROM users WHERE id=:userid',
'getNumUsers');
$db-execute('getNumUsers', array(':userid' = $userId));
$numUsers = $db-getCell('getNumUsers');
// Retrieve a row from the database
if($numUsers == 1) {
$db-prepare('SELECT * FROM users WHERE id=:userid',
'getUserInfo');
$db-execute('getUserInfo', array(':userid' = $userId));
$userInfo = $db-getRow('getUserInfo');
// Retrieve multiple rows from the data
$db-prepare('SELECT friend_id FROM user_friends WHERE
user_id=:userid',
'getUsersFriends');
$db-execute('getUsersFriends', array(':userid' = $userId));
foreach($db-getColumn('getUsersFriends') AS $friendId) {
$db-execute('getUserInfo', array(':userid'=
$friendId));
$friendInfo = $db-getRow('getUserInfo');
// .
}
}
$db-reset('getNumUsers');
$db-reset('getUserInfo');
$db-reset('getUsersFiends');
} catch(DBException $exception) {
echo $exception;
}
Since the object wraps a PDO object, there's no need to sanitize, just
parameterize anything that may be unsafe in a prepared statement. The
retrieval functions will all return the data in a form that's easy to access
so you don't need to worry about getting an associative array when all you
want is a single cell or worry about getting a table when all you want is a
single row. This helps to reduces clutter in your code. Any PDOExceptions
are wrapped with the DBException class that implements an __toString method
that outputs a nice message to make error output clean and consistent.
The interface for you object does little more than replace the mysql_*
function calls with calls to an equivalent function in your oject.
Re-writing your example from above:
$db = DB::getInstance();
$value = 'value';
$db-prepare('SELECT * FROM wherever WHERE field=:val, 'getData');
$db-execute('getData', array(':val' = $value));
foreach($db-getResults('getData') AS $row) {
// Do stuff
}
Resulting in a reduction of 5 lines of code. I may not sound that impressive
for a small example but over the number of times you generally access a
database it will really add up.

Umm I don't think there is a better option, you probably can return the

function standardToMilitary($t)

}
function militaryToStandard($t)
{
return strftime('%r', strtotime($t));

But it doesn't really matter.

I'd try to move to using the mysqli functions or class, which
you can still wrap in a custom object (I do this because
I like to minimize the interface to the bare, bare minimum ...
professional laziness you might say).
does you class need to be php4 compatible? I'd hope
not but you may still have to support php4 ... even then
I'd doubt you'd be using php4 for new project so it
might be worth making a new php5 only class.
I always write with PHP4 in mind. You never know. Besides, I can always
change the internal implementation, if it's a class.
snip
A couple of thoughts. First precede all your mysql_* calls with the at
sign (@) to shut up the routines if they generate text. I had this
problem, and that was the answer.
yes that's very bad advice. using error suppression is bad for performance
and debugging, don't do it unless you really really have to (e.g. you
have some function that spits warnings even with display_errors set to Off)
display_errors should be set to Off in production, and errors/warnings
shouldn't
be suppressed, they should be logged.
handle errors gracefully ('or die()' is not graceful)
I don't know about performance. But every call to the query() method of
my class tests to see the results of the query. If it failed, I call the
proper function from PostgreSQL to fetch the error, and store it in the
class. The query function returns false, if there's an error. So the
user can test the return and then call a function to echo the stored
error.
Second, store your connection resource as a class variable, so you can
pass it around to the various routines. Actually, you're already doing
this, but I prefer to do so explicitly, as:
var $link;
that's very php4.
Yep.
at the top of the class.
I have a similar class for PostgreSQL. I also have routines like
update, which allow you to pass a table name and an associative array
of field values. Same thing for an insert routine.
if the postgres extension is anything like the firebird extension then
there may actually be a few calls which do require error suppression :-)
Probably. When I first started coding PHP/PostgreSQL, I was getting
stuff printed out from the pg_* routines on the webpages and screwing
things up. I was on the PostgreSQL list at the time, and sent an email
to the list about chatter from the pg_* routines. The solution was to
prefix them with @. Works great, but I *do* check for and capture error
text and such.

you use them not for control flow, but for deferring exceptional application
states, which you can then handle in a small number of places as opposed
to scattering the error handling of unlikely events in all sorts of
disparate places.
there is an art to using them, they compliment 'traditional' error handling,
and I agree they can hinder if used badly.
NB: you can have multiple catch blocks:
try {
// do lots of stuff
} catch (ConnectException $e) {
} catch (QueryException $e) {
} catch (DBSelectException $e) {

the problem to some code that knows what to do with it given the context,
if a DB object cannot connect to the DB how does it know what to do in
terms of handling the situation? ... in a webpage you may wish to
redirect, show an error msg or something else (which shouldn't be up
to the object in question and should therefore not be built into it),
in a CLI environment you'd want to do something else maybe.
wrapper functions to handle exceptions as Richard offered is actually
quite neat assuming that the wrapper functions are designed for a
given context (and that they can then assume to be able to handle
the given exception in a way suitable to the given context)

I prefer to deal with the issues locally, or have a documented behaviour with return values and error details available, much like most of PHP extensions/internals. try/catch ends up with weird code organization, imho, especially when you can only really handle some exceptions. For real fun, one API layer will catch all the lower exceptions, then wrap them in a generic exception, and you have to string parse $e-getMessage() to figure out what to *do*.

Re: [PHP] About printing functions

Hi gang,
Lets say that you have a function that prints something to the
output simply like this:
function print_str() {
print blah blah blah;
}
I was wondering if there is a way to use this output and store it in a
var or something without changing the function itself?
And store the blah blah blah somewhere for later use?
I can think of many reasons that someone could use this.
Perhaps you are looking for what the output buffering functions do?

[PHP] Help me understand unit testing?
Hi All, I'd like to understand unit testing better (or, in fact, at all). I understand the broad idea that testing Is A Very Good Thing, but when I have tried to look into it further (for example, have just been looking through the PHPUnit site), I always end up thinking 'This looks like more trouble than it's worth.' I'm sure that's down to me and not the process of unit testing, but I'd like to get some idea of how people on the list actually use unit testing in the real world. I'm assuming that you have your actual application classes and functions designed in their own files, and then you build a series of unit testing classes / functions in their own sort of space, but do you build these in parallel to your application code, or during alpha / beta testing etc? Any practical or even theoretical advice welcome! Many thanks, M is for Murray

Unfortunately, in PHP - like other languages - you can't.
A variable is considered to be null if:
* it has been assigned the constant NULL.
* it has not been set to any value yet.
* it has been unset().
Actually, you can, but it's not terribly pretty. Check for the
variable name as a key in the array returned from get_defined_vars():
?php
$foo = 0;
$bar = null;
$variables = get_defined_vars();
// Check for $foo, $bar, and $baz:
foreach (array('foo', 'bar', 'baz') as $var) {
if (!array_key_exists($var, $variables)) {
echo \$$var does not exist in the current scope.\n;
continue;
}
if (is_null($$var)) {
echo \$$var exists and is null in the current scope.\n;
continue;
}
echo \$$var exists and is not null in the current scope.\n;
}
?
Again, not that pretty, and it only checks the local scope, but it can be done.

Torben
