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. That will be 2 cents, please. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Subject: [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');
}
}
I hate it when I ask a question prematurely, because I could have figured it
out myself. Getter and Setter functions are the answer.
function setNumber($number){
$this-number = $number;
}
$pdf-setNumber('12345');

[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.

Before anybody suggests something like ...

[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?

[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] 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..
---
input type=text size=14 id=start name=start
onkeyup=assessdtime(this.value,'startreport');
onblur=assessdtime(this.value,'startreport'); /
span id=startreportEnter a date and time/span

[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] 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] 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

Re: [PHP] PHP 6 and MySQL 5 for Dynamic Web Sites Book
Hi all. I monitor this list and occasionally contribute as an amateur so please forgive a question that might seem terribly obvious to those in the know. I'm confused about all this PHP 6 talk. Until now I thought I was right up there, because I worked with PHP 5.29 and was ready to upgrade to 5.3. How does it happen that PHP 5.3 has just been released, but books already exist about PHP 6 ? I searched google and so on, but still can't really work out how the PHP development cycle works. Given that PHP 6 exists, does that mean I'm behind the times working with 5.29 or 5.3? I only just figured out that I can get the internet on my *computer*.

[PHP] PHP Manual in PDF format
Hi all. I realize this question has been asked before and I've found responses in the archive, but none of the links work now, or the files they point to are old or unsuitable. I'd like to print the most recent PHP manual to paper, so I need it in a format that's suitable. I've downloaded it from php.net in chm and HTML format but neither of them can easily be printed with proper attention to page numbering and order. Any idea where to find a PDF or similar version of the manual? Thanks, 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. I have made a couple of starts but I have no experience in creating such large applications and I find I often end up with spaghetti code. I've tried using session variables to keep track of where and what the program is doing but there are so many permuations and combinations I found myself writing endless streams of if's, and's and or's just to figure out what page to display. 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? I want to make the code readable and logical in its flow, and avoid repetition of code segments. Much appreciated.

[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 form method=POST action=delete.php 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=smithaddress=hishousetelephone=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
[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...
centerbutton type=submit name=btid value=1Delete/center
centerbutton type=submit name=btid value=2Delete/center
centerbutton type=submit name=btid value=3Delete/center
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 rich...@php.net To: Angus Mann angusm...@pobox.com Cc: php-general@lists.php.net Sent: Thursday, April 02, 2009 8:17 PM Subject: Re: [PHP] Button id's - firefox and IE different ?

[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('','lt;','#60;', '', 'gt;', '#62');
$good = array('(', '(', '(', ')', ')', ')');
foreach ($_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] 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.

How can I pass an anchor tag attribute to a page?
e.g. If I want to echo "1" on page_two:

All you're doing there is setting the variable id to "1". You're not even
printing it.
page_two.php contains:
? echo($id); ?
but page_two is coming up blank after a delay... what I am doing wrong?
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)
?php
// Below: Set the variable id to 1.
$id = "1";
// Below: append the id as a GET variable to the url.
echo "a href=\"page_two.php?id=$id\" click /a";
?
and page_two.php would be:
?php
// Below: Make sure that id was actually appended to the URL in page_one.php
if(isset($HTTP_GET_VARS["id"]))
{
// Below: If it was there, set it as a variable
$id = $HTTP_GET_VARS["id"];
echo "$id";
}
?
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.
Good luck!
