I guess that this is something that would be an issue for many people using mailing lists and/or newsgroups for help, and for all languages - not just PHP. I think that so long as you don't try and mislead the guys who'll potentially be helping you, for example by saying that it's a personal project, or for school, or for a charity site etc. then there aren't really any ethical problems with it - people who help don't do so out of any expectation of a material reward, just out of a desire to make life easier for others who are less experienced or are encountering problems. Sure, I'd be annoyed if I helped someone write 90% of his code and he then sold it, but when you're talking about people answering a few short questions in a forum like this, there's got to be an expectation on everyone's part that they're probably helping you with a commercial project.

Alot :) You have to use forms if you want to pass variables along between pages, unless you use cookies or PHP4 sessions (which use cookies). You could use standard URL anchors for moving between pages and passing variables along - they'd have to be GET type. e.g. page_one.php would be: (although it could be shortened or formatted differently) click "; ?> and page_two.php would be: I suggest you read through the PHP manual some more, especially the section on Variables, and the sub-section "Variables from outside PHP" (http://www.php.net/manual/en/language.variables.external.php). It would also be a good idea to read through some tutorials from some PHP websites, such as: http://www.phpbuilder.com/ http://www.phphelp.com/ Those two should also have some links to other sites.

[PHP] Proper code formatting
Hi all, I'm fairly new to PHP so I don't have too many bad habits yet.
I'm keen to make my code easy to read for me in the future, and for others
as well.
Are there any rules or advice I can use for formatting (especially
indenting) code?
for example how best to format / indent this ?
if ($variable = 'this')
{
do this;
and this;
}
else
{
if ($name = 'bill')
{
do something will bill;
and something else with bill;
}
else
{
assume its not bill;
and do the fred thing;
}
I'm using "PHP designer 2008" which does syntax coloring but if it has
something to automatically indent - I haven't found it yet.

[PHP] foreach and form submission.
Hi all.
I'm writing a script that accepts several different forms with different
content. Depending on what data is sent with the form the script will do one or
the other think.
Before the form data is processed I'd like to scrub it of HTML tags.
I can do this manually as below but the form may have dozens of items of data
so I'd like to automate it.
$_POST['name'] = strip_tags($_POST['name']);
$_POST['address'] = strip_tags($_POST['address']);
$_POST['phone'] = strip_tags($_POST['phone']);
I saw a few lines of code once that used "foreach" on the $_POST array
elements and it did not seem to matter how many or what names the elements had.
Conceptually like this
foreach ($_POST - element) {
$_POST-element = strip_tags($_POST-element)
}
Any ideas please ?
Thanks.
Re: [PHP] foreach and form submission.
Thanks Ashley...that did the trick.
After reading about the limitations of strip_tags I decided to just replace
the bad bits as below...
It still uses your "foreach" suggestion but replaces "<" and ">" with "("
and ")" instead of stripping tags.
I think I will extend the good and bad arrays to deal with magic quotes also
!
$bad = array('<','<','<', '>', '>', '>');
$good = array('(', '(', '(', ')', ')', ')');
foreach ($_POST as $key => $value) {
$_POST[$key] = str_ireplace($bad, $good, $value);
}
I'd do something like this, so as to preserve the original post data
array:
$data = Array();
foreach($_POST as $key => $value)
{
$data[$key] = strip_tags($value);
}
Note that strip_tags() will not be able to decently clean up messy code
(i.e. code where the opening or closing tags themselves aren't formed
properly)

[PHP] Button id's - firefox and IE different ?
Hi all.
I want to have several delete buttons with just one form, and depending on
which button is pressed, one of several items is deleted.
So I need multiple submit buttons for 1 form, each displaying the same text
"Delete" to the user, but each with a different "value" so the PHP script can
tell them apart.
I've used this code for the buttons...
Delete
Delete
Delete
And it works just fine with firefox. But IE does not seem to pass the value
back to the btid so when the script asks
if $_POST['btid'] == "1" {
}
the value 1, 2, or 3 is not given back to PHP by IE. It is given back correctly
by firefox and works fine.
Any suggestions ?
Thanks.
Re: [PHP] Button id's - firefox and IE different ?
I can do as you suggest below, but then the buttons are labelled "Delete" "Cancel" and "Save" to the user. The essential point is that they all need to say "Delete". I know I can accomplish this by making multiple forms, each with its own button but for my purpose that's a pain is the ***. IE returns the text displayed in the button regardless of the "btid" value. It seems to just ignore it. Firefox returns the value assigned to "btid" as I intended regardless of the text in the button that the user sees. - Original Message - From: "Richard Heyes" To: "Angus Mann" Cc: Sent: Thursday, April 02, 2009 8:17 PM Subject: Re: [PHP] Button id's - firefox and IE different ?

[PHP] Directing form to different handlers?
Hi all. I realize this is more an HTML question than PHP but I'm sure someone here can help. I have several forms with lots (dozens) of text inputs. If the user presses the "Update" button I want the form handled by "update.php" but if they press "Delete" it needs to be handled by "delete.php" or "add.php" and so-on depending on the button they press. But when establishing the form I can only have or "add.php" or whatever. Is there a way to direct the content of the form do a different handler depending on the button? I know I can use javascript to direct to a constructed URL and append ?name=smith&address=hishouse&telephone=28376.and so on but this is not practical when there are dozens of entriesthe URL becomes massive. I prefer to use "POST" and then use PHP to extract the POST array. Any ideas? Much appreciated. Angus
Re: [PHP] Directing form to different handlers?
Thanks to all posters for their input. For what it's worth, I'm writing a PHP application for a very specific purpose of running my office billing etc so I have total control over the JavaScript settings for users. The entire application would break without JS so if they turn JS off, all they get is a page telling them to turn it back on. I know I could direct all form submissions to one handler, and easily figure out which button was actually used to submit the form and use a SWITCH, but I like the idea of having the code in smaller segments. It makes it easier for me to find what I'm looking for. Just a personal preference. I actually found some nice JS to change the form action dynamically using by using the button to set the value of the variable "handler" to "edit.php" or "delete.php" etc etc document.myform.action = handler; document.myform.submit(); Thanks again.

[PHP] Web application design considerations - a good reference ?
Hi all. I'm working on a PHP project for my own personal business use. It will handle billing and invoices as well as payments and time management, bookings, appointments and a few more. I may add things like personal messaging between the various users and a customer login to check on the progress of their accounts. It is a big project and will probably take a year or so to complete in my spare time.

The code is not the probblem for me...it's the flow and organization of the code. Can anybody point me to a good book or tutorial that lays down the principles and gives some suggestions for integrating the many subroutines of a large application?

[PHP] Strange behaviour with uploaded files .. XAMPP on Windows

When I use a form to upload a file, using $_FILES['uploadedfile']['name'] and move_uploaded-file($_FILES['uploadedfile']['name'], $targetpath) strange effects happen.

When I go to delete the file, or the entire uploads folder, the file is not deleted, nor the folder.

[PHP] uniqid() and repetition of numbers generated
Hi all. I'm sure I can't be the first person to ask this question but a search of the net leaves me confused. I need a unique identifier in an SQL table and for complicated reasons I don't want to use auto-increment. So I thought I would use a pseudo-random method instead. I am NOT scared of people guessing the unique identifier, it just has to be unique in order for the database to work properly. So I looked at the uniqid() function and see it is based on the "current time in microseconds" and when I test it out I see that it increments (very quickly) when run repeatedly. If it is based on JUST the time, then it should repeat every 24 hours, thus making "collisions" possible, which I don't want. If it is based on the time AND day, then that's fineI can use it. So here's the problem When I calculate the number of microseconds since 1970 I get a 16 digit number. But uniqid() only gives a 13 digit number. Calculating the number of microseconds in a day gives 11 digits. So it seems to me that the numbering sequence will repeat every 100 days, which risks collisions also. Can someone explain how uniqid() is really calculated, so I can make a proper judgement about how to use it? Please don't suggest using a hash of a number generated by uniqid(). Hashing a small number into a longer one does not add entropy, it just transforms the input number, so it does NOT alter the risk of collisions so there is no net advantage. I had a thought to just append the current date to the uniqid() result but I'm interested to know if anyone has a more elegant solution. Thanks in advance. Angus

I had a thought to just append the current date to the uniqid() result but I'm interested to know if anyone has a more elegant solution. Thanks in advance. Angus Auto increment fields are designed to avoid collisions. I can't think of any sensible reason for not using them. If you're worried that users of the system will think a number like '65' is a 'silly' value for an id, why not pad it up with leading zeros, and maybe add in some text from their name or something. To me, one unique number is the same as another, whether it has 11 digits or 2. Also, without having numbers with many leading zeros in your 11-digit unique number, the value range will be dramatically reduced, thereby increasing the chance of you running out of unique values. Thanks, Ash http://www.ashleysheridan.co.uk Thanks Ashley. To clarify, the reason I don't want to use auto-increment : different users with their own populated databases may wish to merge some or all of their data. The unique identifier needs to be carried along with the rest of the data, hence be unique not only on the database it currently resides in ... it still needs to be unique if it gets copied into another person's database, and auto-increment will not meet that requirement. I thought that using microtime (hence uniqid()) will solve the problem, and the only chance of a collision is the unlikely event that by chance, records are added to 2 different people's databases at EXACTLY the same time, to within an accuracy of a millionth of a second. Possible I realize, but very unlikely, given that each user will probably add less than 100 entries per day. On balance I think I will generate an identifier consisting of a few things...uniqid() plus a a few letters from the person's name plus a (pseudo)random 3 digit number. Probably there's enough entropy in that for my purpose. But the question still remainswhat exactly is being returned by uniqid() ? It is obviously not random, and not a hash function because it increments predictably. It's too short to be the number of microseconds since 1970 and too long to be the number of microseconds since midnight. Since it has a fixed length, and it increments, it will eventually get to the last possible number - when will that be, and what will happen - will an extra digit appear or will it go back to zero, or will the generating algorithm crash? If it's anything similar to the unix timestamp then we're all in trouble on January 19, 2038 !
Re: [PHP] uniqid() and repetition of numbers generated
Here's part of the confusion: If you were to express the number of microseconds since 1970 in a decimal number, it would indeed take 16 digits. But uniqid() returns a /13 character string/, not a 13 digit number. The string is actually a hexadecimal number (and thus can express a greater range of values than a decimal number within those 13 characters). -John Ahh! The moment when the penny drops. I was looking at the result as a number, not a string. Solution to problem = use uniqid() -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

1. Is possible. Google the term web-bug. Be prepared that it will only work if the recipient has a HTML enabled email reader AND allows downloading of images.

Just embed an image with a unique filename (tiny or invisible if you want) in the email and make it's source your server. Then track requests for that image. 2. Is impossible. It just is.

[PHP] PHP sessions, AJAX, authentication and security.
Hi all. A question about PHP sessions and their interaction with AJAX. I have a database containing sensitive information and users need to log in to my PHP script and be authenticated before they are granted access. For one of the forms I would like to retrieve information using AJAX, and some of that information is sensitive also. The request from AJAX is handled by another, simpler PHP script. It occurs to me that the AJAX handler could be used to bypass the user authentication and a crafted request sent directly to the AJAX handler to get information without authentication. Can anyone offer some advice about how to piggy-back the session/authentication data that the user originally used to the AJAX so that only an authenticated user will get a valid response from the AJAX handler? I know I could embed authentication information into the web-page and send this with the AJAX request but I'm interested to know if there are other methods also. I hope the explanation is clear. Thanks in advance.
Re: [PHP] Re: PHP sessions, AJAX, authentication and security.
same as everywhere else in your apps.. ajax is no different in any way
at all, not even slightly. as far as PHP and web server is concerned
it's just a plain old request same as any other; thus..
if( !$_SESSION['is_logged_in'] ) {
exit();
}
// do stuff
Thanks for that. Sometimes the solution is right there in front of you.
The bit of code below does the job nicely for me :
session_start();
if(!isset($_SESSION['username'])){
echo("Go Away.");
exit();
}
// now work with sensitive data...

[PHP] Checking for internet connection.
Hi all.
I'w writing a PHP app that is designed to run over a LAN, so internet
connection for the server is not really essential. Some users may
deliberately not connect it to the internet as a security precaution.
But I'd like the app to make use of an internet connection if it exists to
check for an update, and notify the user.
Is there a simple way for a PHP script to check if it has an internet
connection?
I thought of this :
if(fsockopen("www.google.com", 80)){
// we are connected
}
Is this OK or is there something better for the purpose?

Re: [PHP] Checking for internet connection.
Why can't you put the update on the same LAN server that the app resides? If that is not possible, what about using CURL, and update if it can connect successfully, but don't if it cannot? Thanks, Ash http://www.ashleysheridan.co.uk Since the LAN is remote (many hundreds of miles away) from the source of the update, the only practical way to deliver an update every month or week to multiple users is to make it available for download from a central "update server". I'm just trying to maximize efficiency by checking if an internet connection exists, and abandoning further attempts to check for update availability if it does not. The idea to use CURL seems valid, but it pre-supposes that I know the answer to my own question. To use your suggestion, I'd have to have some mechanism to detect if it "can connect successfully". I'm asking what that mechanism should be, and if the one I've suggested is good, or flawed in some way.
[PHP] strtotime - assumptions about default formatting of dates
Hi all. I need to allow users to enter dates and times, and for a while now I've been forcing them to use javascript date/time pickers so I can be absolutely sure the formatting is correct. Some users are requesting to be able to type the entries themselves so I've decided to allow this. I'm in Australia, and the standard formatting of dates here is DD/MM/ or DD-MM- I recognize this is different to what seems to happen in the US, where it is MM/DD/ or MM-DD- When I process an entered date using strtotime() it seems to work fine. But of course I am concerned when dates like January 2 come up. I find that 2/1/2009 is interpreted as January 2, 2009 on my installation, which is Windows 7 with location set to Australia. But can I be sure that all installations of PHP, perhaps in different countries and on different operating systems will interpret dates the same? I can't find much mention of this question online or in the manual. Any help much appreciated. Angus
Re: [PHP] Re: strtotime - assumptions about default formatting of dates
I wrote a little AJAX gadget which sent the string typed to a PHP backend
which parsed it using strtotime and then formatting it out again as
something unamiguous (like 2 January 2009). Then every time the date entry
field is changed by the user (with an onKeyUp event), this AJAX call is
triggered and displays the unambiguous form next to the input box, so
users can see how their entry is being interpreted.
Of course, there's some overhead in the AJAX calls, and it requires
JavaScript.
If you wanted to do without JavaScript you could do a similar parse-format
sequence when the form is submitted and show a confirmation page with your
server's interpretation of the date.
Cheers
Pete
I took this idea and wrote an ajax so that on keyup or blur, the entry is
sent to PHP which puts it into strtotime() and if a valid result comes out,
formats it something like "Wed January 23, 2008 6:23pm". If the result is
invalid, it outputs an "Invalid" message. This is then displayed in a span
next to the textbox.
So as the user types they can see if what they entered is valid, and also
see how the date/time will be interpreted. Works beautifully, and makes the
form very usable.
For what it's worth, here is the code:
The PHP ajax (called judgedatetime.php:
---
$inp=$_REQUEST['a'];
$a=strtotime($inp);
if ($a < 1200103200){
$b="Invalid";
} else {
$b=date("D M j, Y g:ia",$a);
}
echo $b;
?>
The Javascript
---
function assessdtime(dTime,putHere){
AjaxRequest.get({'url':'ajax/judgedatetime.php',
'parameters':{'a':dTime},
'onSuccess':function(req){
document.getElementById(putHere).innerHTML=req.responseText;
}
})}
And HTML embedded in the page..
---
onkeyup="assessdtime(this.value,'startreport');"
onblur="assessdtime(this.value,'startreport');" />
Enter a date and time

[PHP] Luhn (modulo 10) check digit calculator
Hi all. Perhaps a lazy request, but does anybody have some cut-n-paste code to calculate a Luhn check-digit? It's a check-digit often added to the end of things like credit card or account numbers to make detecting typo's a bit easier. I found lots of code to validate a number once the check-digit is applied, but nothing to calculate the digit in the first place. Thanks in advance ! Angus

[PHP] Speed of sending email .. can I put them in a queue rather than wait?
Hi all. I'm currently using the phpmailer class from phpmailer.worxware.com to send datatbase -populated emails to clients. At the moment I'm runninng PHP on Windows and using the built-in sendmail equivalent packaged with XAMPP. It uses a remote SMTP that authenticates by prior logging into a POP account. The number of emails sent is very small. Each one is only sent after a user fills out a form and presses send. But there is a noticable lag of about 5 or sometimes 10 seconds after pressing "send" before the user sees the "Mail sent" page. I presume the reason for the lag is the time spent logging on and off a remote POP, then SMTP server, transferring the data etc. It would be better if this happened in the background - that is, the user could get on with doing his next task while the emails sat in a queue in the backgorund, being lined up and sent without PHP waiting for the process to finish. Can anybody recommend a good way of doing this? Is Mercury Mail going to help me here?
[PHP] Strange behaviour with str_ireplace()
Hi all. I found some unexpected behaviour with str_ireplace.
To summarize, if the $replace term is a number, but formatted as currency with
trailing zero's (34.50) the function drops the trailing zero.
Example :
$price=34.5;
$message="You owe me #amount#.";
$message1 = str_ireplace("#amount#,sprintf("%01.2f",$price),$message);
$message2 = str_ireplace("#amount#,"$".sprintf("%01.2f",$price),$message);
$message1 will yield "You owe me 34.4"
$message2 will yield "You owe me $34.40"
So in other words, if the replace term can be interpreted as a number, it will
be, including truncation of zero's.
I didn't expect this, because as the function name suggests, it's a *string*
replace.
Fortunately I can just add a $ to the amount and make it work as a string, not
a number but this would not always be the case.
Is this by design, or is it a bug?

Re: [PHP] Re: UK Project Opportunity
This thread's getting a bit tired but here's my $0.02 worth. I've always found the phpclasses website a bit confusing to navigate and I've never had much success finding what I want. But it's free and as a non-paying customer I don't feel entitled to complain, when probably a bit more work from me would find what I was looking for. As for advertising, well so what. It's there and my eye is pretty well trained to ignore it. No big deal to me, and if it's a necessary thing to pay for a free site, then so be it. The site could do with an easier interface and I look forward to seeing it in action, but I think it's a bit too much to complain and swear and criticize the owner if you're not paying for what he provides.

[PHP] Recommendation for online PHP editor please....
HI all. I'm looking for a recommendation for an online PHP editor. Here's what I mean I mean a PHP program I can install on my web-server, then log in and use it to browse and edit other PHP files on the server. The idea is that I could make changes and bugfixes to a web app while I'm away from home/office. Ideally it would be more than just a text editor, but also have syntax highlighting and formatting for PHP built in. Any recommendations would be much appreciated. Thanks, Angus
[PHP] FPDF passing values into header and footer?
Hi all. Whilst this question relates to fpdf (www.fpdf.org) I think it really
is a PHP question, because it involves passing values into classes and
functions.
Here's the problem .. I need to pass a PHP variable like $number into the
header of a PDF.
I have extended the FPDF class as follows
class PDF extends FPDF{
function Header(){
$this->SetFont('Arial','BU',12);
$this->Cell(0,5,'User notes for invoice number '.$number,0,'1','L');
}
}
The problem is, I can't figure out how to pass a value from the rest of the PHP
script so it can be seen within the function above.
I'm sure the problem is one of the scope of the variable but this sort of thing
is new to me and I can't figure out the syntax to make it work.
Before anybody suggests something like ...
function Header($number){}
Please recognize that the Header function is called automatically by FPDF and
not by my code, so unless I totally hack the FPDF class I can't do this easily.
Any suggestions please?

Re: [PHP] Need login suggestions
We're building a large site for a school district, to be used by both students and parents. When a student logs in, they gain some access to the site, and when a parent logs in, they gain access to other sections on the site. That's all fine and dandy, it's the actual registration process that I'm having a hard time with. How to determine if a registration is a student or a parent. Do I simply give them a check box (or other method) to pick from (student or parent) and hope they're being honest? Has anyone here have to deal with that in the past, and would you be willing to give me some ideas of what you did? Thanks! It sounds like it really doesn't matter how you do it. Nothing bad happens if a student registers as a parent or vice-versa and the only person inconvenienced is the end-user. I would just take some simple steps to ask the person if they want to view as a student or as a parent. Have you considered the option of just letting people register, and then allowing them to select a radio-button labelled "Show me information important to parents" or "Show me information relevant to students" or "Show me information relevant to both". Some users might quite legitimately want to see both sets of content.
