Re: [PHP] sessions
Nothing is safe unless it goes over SSL, and even then, NOTHING is 100% secure :) The point is that you shouldn't have the plain text password as a session var... Your login form (and the script that varifies the login) should be secure (see note), and should establish a session var like logged_in NOT session vars like password. This way, IF the session is hijacked, the hijacker can only hijack that session NOT find out what the user's password is. Note: The real issue you have is that the password can be seen in plain text when the login form is submitted... therefor, you need to be concerned about running the login process under SSL.

Re: [PHP] PHP Online Store
You only have two options really... either they manually change each product themselves via a web based form, or the process is managed by a CSV file. The first thing you need to ensure is that every product in the catalogue has a unique key (identifier / product number / barcode number / whatever). This value needs to be present in the database, and in the case of a CSV file, needs to match the CSV. You take the following CSV: '10034','Socks - Red','2.99' '10485','Socks - Blue','3.24' And parse it into your database, where you'd have columns like: id,description,price They can change the description all they want... they can also change the price, but they need to leave the id alone. If they change the ID, it's like a new product. If their supplier can't supply an Excel or CSV file, or doesn't have unique codes for each product, then your client has no choice but to manually update the data themselves via web forms, or maintain THEIR OWN Excel file which you can parse weekly/daily/whatever. I'd avoid doing anything manually. Try to get an agreed format CSV from the supplier monthly, and parse it.

It's possible you're being afflicted with the same problem I am. See
the message just one or two above this about Sessions problem. What I
found in my debugging is that it had to do with how I was
mix-and-matching the way I specified links.
Short version of the problem is that http://mysite.org/ has one session
and http://www.mysite.org/ has another. In my code, I sometimes have
the links as a href=/page and sometimes it's explicit, as a
href=http://www.mysite.org/;. So if a user went to the site as
http://mysite.org - the pages that used the explicit www.mysite.org
would fail.
So if there's anything in your pages/links that may change how the link
is referred, you may be have different sessions occuring.
I would imagine it should be pretty easy for you to debug whether or not
this is the problem. Have each of your pages echo out the current
session id (echo 'session is '.session_id().'br';) and see if it
changes at any point, and especially on the pages that fail.

This is a pretty simple debugging type query, so:
First things first, make sure that $annrow[id] is what you expect, by
echoing it to the screen.
?
echo $annrow[id] . br /;
?
Then your file_exists() line has to use double quotes, because you're using
a variable:
file_exists(cherpdocs/$annrow[id].doc)
Or better still, clarify exactly what you want by using {braces} or .'s
file_exists(cherpdocs/{$annrow[id]}.doc)
Or:
file_exists(cherpdocs/ . $annrow[id] . .doc)
Same applies to your echo line.
Summary, I think you can save yourself a little grief by making the
following changes to your code. Personally, I prefer wrapping all vars in
{braces} if inside a string. It also includes some minor debugging code, so
that you can hunt down the issue.

$file = cherpdocs/{$annrow[id]}.doc

I haven't included every little line and data check that I should (otherwise
you'd have to pay me :P), but it works.
The beauty of keeping it all in one script is that you can echo the POSTed
variables back out into the form, with an error message.
This should be a suitable framework for you to further develop into your own
application.

PHP is some kind of programming language which is PARSED by PHP. The result
is a TEXT FILE of some description... yes, even a CSS file.
How to do it depends entirely on your database structure and what you want
to achieve.
But a quick example:
---
?
$textColour = 'FF9900'; // a var you retrieved from a DB
$bgColour = 'white';// a var you retrieved from a DB
?
P { color: #?=$textColour?; }
BODY { background-color: #?=$bgColour?; }
---
Will php commands executre from a .css file or is there a different way to
do this??
.css files will not *automatically* be parsed by PHP, however you can force
them through with either a .htaccess file, or by editing apache's httpd.conf
file to suit.
this is my .htaccess file:
Files dynamic.css
ForceType application/x-httpd-php
/Files
Or, you can just include() some CSS generated by PHP directly into your PHP
application, and it will just appear as part of the HTML source.

Re: [PHP] Truncating text
Take the truncating out of the picture, and just concentrate on returning
two results from mysql. If that works, then try it with rows that contain
an exclamation mark (!).
If they both work, THEN concentrate on truncating the variable down.
Let us know how far you get, so we can pinpoint the problem.

Re: [PHP] Code Validator
You need to validate the RESULT of the HTML/PHP source being processed by PHP, resulting in pure HTML source, which is what your browser sees. So, upload your pages to a server which can be accessed over the internet, then go to somewhere like validator.w3.org, enter the URL, and it will validate it. If you're looking for an OFFLINE validator, then I think you'd need to View Source on the resultant HTML output, copy and paste into a text editor, save it, then run it through your validator.

First, if there are any you know of and want to recommend, please post. Secondly, if I do build it myself would it be better to write this log to file or mysql db? Right now I only get like 200 page views a day but still am concerned about resource use since I'm on a shared server. It depends how detailed you you want it broken down by: - page - page and month - page and week - page and day - page and hour - page and minute - page and second Personally, I have two tables: counters_page (id, url) counters_hits (page_id, stamp) My counters.inc script does the following: - looks to see if the current URL is already listed in counters_page - if it is, it grabs the id - if not, it inserts and creates a new id - inserts a record into counters_hits with the page_id, and a unix timestamp of when that page was hit. This way, I know the exact second that a page was hit... So I can perform report on that data, selecting how many hits for each page within the last week, month, year, minute, 30 seconds, etc etc. This *IS* a little expensive in terms of data storage though. Each hit to the site costs around 20 bytes. A site I recently launched has attracted 37,000+ hits, so we're already looking at 740k of data. However, this table layout IS more economic than recording the entire URL of each hit... instead we only record the id of the URL. If I were only concerned with days, or months, I'd choose to store less data (and may still!!)... for example, a current timestamp is 10 chars long, wheras storing 2003-03 is only 7 chars (but only cares about the month, not the day, hour, minute, second, etc). The key issue with the above design is NOT how long it takes to record the data (I have never noticed any performance hit on my code, even on a very busy shared server). It seems to be (although not drastic AT ALL) at the point where I choose to report. It's a LOT of information to plow through, and it will get worse :) There are plenty of things I can do though... I can archive reports, I can cache queries, I can perform monthly analysis, etc etc. To me, the most important factor is the data, and I know I've got exactly what I want.

Re: [PHP] HELP PLEASE ! Need PHP Advice !!!
Right, well there's a few issues here. 1. You're asking if there's a way to parse a QXD file so retrieve the text from it. I doubt this can be done. I had a quick google for it, to no luck. I also bothered to open up a Quark 3.32 file in my text editor, to check out the source. It looks pretty complex. However, there MAY be some light at the end of the tunnel. a) PHP *IS* able to read and write PDF format. Prerhaps if your newspaper designers export a PDF of the newspaper (relatively easy). you can pick up the pieces you need through the PDF, rather than the QXD file. b) What you're really talking about is using one set of data in multiple ways (web print, then maybe email, WAP, PDA, etc). What I'd be aiming to do is have all the text/content stored in a shared database or easy-to-parse file format (like XML), so that the writers write to this format, then the designers copy + paste to Quark, the editors can edit directly in the XML file or via database GUIs, and people in charge of other content formats (like web_ can either copy + paste from the central content, or parse it with a program like PHP. c) Perhaps your company should look at Adobe InDesign 2 -- I read an article which briefly discussed it's ability to parse or read from XML files -- so you could have a simple XML doc: --- article id28/id titleLearning about XML/heading subtitleI wish I had time to explore this properly!/subtitle authorJustin French/author email[EMAIL PROTECTED]/email keywordsXML,Justin,Foo,Bah,PHP/keywords content p class=introIn this article, I'll attempt to show you some blah blah./p pParagraph 1/p pParagraph 2/p pParagraph 3/p p class=footerThis is my footer/p /content /article --- I *think* InDesign 2 can take this data, and with the designer's help, format it to a designed article. At the very least, you could export some nice clean plain text for the designer to copy+paste, which is probably what they already do (copy+paste from Word to Quark. 2. Image files in Quark need to be either TIFF or EPS format. So, what you need is a way of copying these files, converting them to JPEGs, GIFs or PNGs, and resizing them to suit the web. I don't really know if the image functions in PHP can do this... best left to others. You *could* batch convert everything to a RGB JPEG using photoshops batch processing and actions, THEN get PHP or Photoshop to do the resizing etc. However, cropping and whatnot of a file is often something that can ONLY be done by eye... You may never be able to achieve this with automated computer programs. Think about the real issue. Is it taking stuff from quark and messing with it, or is it having a good clean source of data which can be used many ways?

nothing I've read advocates doing this, and I've never had a problem
with my code when I've written it this way.
Wrapping vars in braces helps clarify the code, and can avoid problems like:
?
$price = '44.99';
echo Price: US$$priceeach;// probably won't work
echo Price: US${$price}each; // will work for sure
echo Price: US$ . $price . each;// will work, but not my pref
?
I've also found it helps with things like:
?
echo a href='{$_SERVER['PHP_SELF']}'click/a;
?
... where normally the single quotes would cause confusion, or require the
href to be wrapped in escaped double quotes.
In otherwords, wrapping $vars in {braces} provides clarity to both the PHP

Archiving a report, rather than archiving the raw data can save lots of space, and yes a cron would be the best way. the downside is that the report is the ONLY record of the data. 2. Have the counter dump the visitor info into a DB (probably MySQL), then process the data whenever the administrator wants to view his stats. On-demand stats will use up more space long-term than generating monthly reports or something... but there are obvious benefits. The biggest issue IMHO is that if your site is processing a large amount of data, processing it over and over and over on demand is going to burden the server. Anyone have any suggestions or considerations on which method would work better? Is there something else I should do instead? If you're going to be dealing with large amounts of data, a combination. Perhaps perform a monthly analysis and consolidation of data to keep on demand / real time processing to the current month only... However, make sure you keep the long-term data SOMEWHERE, in case you want to change the reporting, method, or analyse the data a different way.

Re: [PHP] Logging Referer
on 22/02/03 10:19 AM, Matt Honeycutt ([EMAIL PROTECTED]) wrote: I'd also like for it to log the referer, but because the counter is triggered via an img tag, the referer is always the page that has the img tag. Is there any other way to grab the referer that actually sent the user to the page that contains the counter? I'd like for the counter to work even when included in static HTML pages, so the including page cannot use any PHP to help facilitate this logging functionality. No, not easily :) On PHP pages, you could get the referrer, and append it to the URL, forcing the correct REFERRER through to the img script: img src=makeMyCounter.php?ref=?=$_SERVER['HTTP_REFERRER']? And you *could* choose to force .html files through the PHP parser, so foo.html could use the above code. I think the other alternative is to use javascript to build the img tag, because I'm pretty sure JS can figure out the referrer. But this has the obvious downside of JS being NO WHERE NEAR guaranteed to be on each browser. I think i'm missing something though, because I *think* those free counter/stat programs DO log a referrer... wait -- just checked thecounter.com, and they DO use JS for the referrer.

Re: [PHP] sessions
on 21/02/03 5:34 AM, Joseph Bannon ([EMAIL PROTECTED]) wrote: I'm starting to use sessions for my website and wanted to know some things before I fully commit to use them. 1) How are sessions different from cookies other than where the information is stored? A session is just a method of maintaining state (ie, a way of recognising the same browser/client on each request). One of the methods for maintaining this state is cookies, the other is by passing a SID around in the URL. In the case of cookies, the ONLY data being stored client side is a session ID... if you choose to *entirely* manage your session via cookies, then you'd have to store more data on the client side cookies (uid, pass, preferences, etc). 2) Does session data stored on the server automatically delete after a certain time? Yes. There's a lifetime setting (seconds), and there's a garbage cleanout routine. Once the garbage probability has been triggered AND the session lifetime has expired, THEN it gets deleted. 3) Is a session id created for each user per each browser or just per each user? Each BROWSER/CLIENT... in the case of cookie based sessions, the cookie is set on the browser, containing a session id... Yes, the user could spoof the cookie on another machine and continue the session, but I dount that was your question. Same with URLs -- the session is passed around via URL, the user *could* grab the SID out of the URL, and append it to another URL on another browser/machine.

Re: [PHP] Date/Time Logic
I assume you talking about a logged in, validated user -- because there's no way to prevent a user from deleting their cookies, or changing their IP, or using a different computer to access the site. My only suggestion is that you create a user/pass login system, maintain it with sessions, and make the site members-only. As part of the sign-up process, keep a timestamp of when they joined, and each time they log-in, check that their stamp is within the limits set. Next time they login after that date, you can use their login as the trigger to: a) set the account to invalid b) send the admin a report email c) update any other data and tables d) prompt the user to buy more time, or whatever By keeping timestamps of when they signed up, when they last logged in, you can also build reports about who has logged in, who is about to run out of time, who needs a reminder email sent about buying more time, and even run some garbage cleanout stuff, so that users who have expired, and haven't shown up in 2 months get auto-deleted or whatever. Some of it could be done with cron jobs, or you could just choose to run a script from your browser daily/weekly/yearly to trigger the processing. Justin on 20/02/03 5:50 AM, Brent Baisley ([EMAIL PROTECTED]) wrote: It sounds like you're asking for triggers, which are available yet.

Re: [PHP] problem with mysql / auto increment fields.. ?
if you check on the FIRST insert (the primary table that holds master usernames) to ensure the uname doesn't exist, THEN do the other queries, there shouldn't be a problem. I think the key here is that you're using the username as the unique key, and putting that username in multiple tables... really, you should be taking advantage of mysql's auto-increment on an ID field... therefor the username brad_is_the_best_2002 is an alias of userid 204... all your other tables (bb etc) should be using 204 as the id, not brad_is_the_best_2002... 1. gives people the chance to change usernames, because the ID is primary, not the username 2. saves HEAPS of space: Consider using 10 character unames everywhere: 1000 users x 10 char uname x 10 BB posts each = 100k of data -- not too bad 5000 users x 10 char uname x 50 BB posts each = 2.5meg of data -- an issue 5000 users x 15 char uname x 50 BB posts each = 3.75meg of data -- an issue Then consider using 4 byte userIDs (like 1042) everywhere: 1000 users x 4 byte uid x 10 BB posts each = 40k of data -- better 5000 users x 4 byte uid x 50 BB posts each = 1 meg of data -- 60% space save 5000 users x 4 byte uid x 50 BB posts each = 1 meg of data -- 74% space save ... and in practice, the first 99 uid's will only be 2 bytes, the next 900 will only be 3 bytes, etc etc. I'm no database expert, but I guess that's the point behind relational databases... the same user can be related to many tables, using just a few bytes of data, rather than a 6-20 character username. So, after your first insert into the primary user table, you would find out what ID you just inserted with mysql_insert_id(), and use THAT to insert into the related tables... Of course, your BB may require a full username, and lots of your other architecture may have to be changed, but I'm just pointing out that it's worth getting this stuff right, because one day you'll copy the same code/structure to another site, and it may attract 100,000 users really quick, and you might end up with a MASSIVE data problem REALLY quick -- it's happened to me :) Justin French on 20/02/03 11:34 AM, Chris McCluskey ([EMAIL PROTECTED]) wrote: MySql should insert a value into that column when you update if you are using an auto_increment field. this value will always be unique. period. -Chris -Original Message- From: Chad Day [mailto:[EMAIL PROTECTED]] Sent: Wed 2/19/2003 1:16 PM To: php general Cc: Subject: [PHP] problem with mysql / auto increment fields.. ?

Re: [PHP] ishttp://username:password@localhost.com/secure_area/ secure ?
First things first, ANYTHING you do without https:// (SSL) is insecure. Anything you do with SSL is more secure, not secure. Which answers 90% or your questions. If you are stuck with the username:password@ in the URL, my guess is you could get your current URL, use parse_url to check if it has the uname and pass bits in it, and if so, rebuild the URL without them, and redirect... it could be quite messy, and I haven't thought it through tho!!

Re: [PHP] Sessions Timing Out Too Often
Did you look in the manual first? Didn't think so. php.net/session first search result is http://www.php.net/manual/en/ref.session.php There are two PHP.ini settings you should look at: session.gc_probability specifies the probability that the gc (garbage collection) routine is started on each request in percent. Defaults to 1. session.gc_maxlifetime specifies the number of seconds after which data will be seen as 'garbage' and cleaned up. if you can't change the settings yourself in php.ini (or ask the host to), then i'm 99% sure they can be over-ridden on a per-directory basis using a .htaccess file (apache assumption here). Something like (guess): IfModule mod_php4.c php_flag session.gc_maxlifetime 1440 /IfModule Of course, all this was available by: a) searching the manial b) searching the archives, where this gets asked weekly :) Justin French on 19/02/03 12:59 PM, Monty ([EMAIL PROTECTED]) wrote: I'm finding that my sessions seem to be timing out fairly quickly.

Re: [PHP] Protecting files
My preference 1. if possible, store the files above your public_html directory (doc root)... this means they cannot be over http:// by apache, if that isn't possible: 2. use .htaccess to either block the entire directory of includes, or all *.inc files, or whatever you think is best. Personally, I block *.inc across all my sites, via a .htaccess file in the doc root: Files ~ \.inc$ Order Allow,Deny Deny from all /Files 3. I don't think permissions (chmod) of the file will help much, since apache needs to read the files for them to be included... you should make sure that other users on the server cannot include() your .inc files from their account... if they can, find a new ISP ASAP, because they're obviously DUMB. I personally don't like the idea of naming all inc files *.php, because there is a CHANCE that they might be executed out of context (imagine if you had an include file which (stupidly) worked fine within the context of your whole site, but accidentally deleted a whole table of data if executed on it's own... YUK!!). The upside of naming them .php is that if the server's sys admin accidently takes away permission for .htaccess files, or you accidentally delete your own .htaccess file, you're still protected. Perhaps you could consider BOTH: Files ~ \.inc.php$ Order Allow,Deny Deny from all /Files ... this will prevent them being served at all... in the event that the .htaccess is deleted or disabled, you can rest easy that PHP will parse them, so that they cannot see the raw file.

Now when they come to your website if they are not logged in your website checks for this unique id in the cookie, if the cookie exists it references it against their user account, if the unique id matches the system logs them in. This method is also nice because you can invalidate all automatic logins by clearing the column in your database. Please note the unique ID will still be sent in the clear so someone sniffing the traffic could still pick it up, if you force them to login once every n days it can help reduce this, also prompt for the password for any critical events like changing their profile.

I'm not too good with Apache yet, but an example would be: Files ~ \.jpg$ Order Allow,Deny Deny from all /Files Files ~ \.gif$ Order Allow,Deny Deny from all /Files Files ~ \.jpeg$ Order Allow,Deny Deny from all /Files Files ~ \.bmp$ Order Allow,Deny Deny from all /Files (you might also choose to block everything in imageDir/, which would also include the xml file) Then you need to create a script called image.php which: a) accepts file=.xxx in the URL ($_GET) b) sets the appropriate image header c) passes the image file though Instead of you calling img src='imageDir/picture.jpg' / You would call img src='image.php?file=imageDir/picture.jpg' / You also need to ensure that users can't directly call image.php?file= picture.jpg in the browser, which can also be done with apache / .htaccess files. Files ~ \image.php$ Order Allow,Deny Deny from all /Files There's plenty of examples of passing images through in the manual... in particular one of the user-contributed notes by lists at darkcore dot net 08-Aug-2002 03:24 at http://php.net/header looks about right.

Perhaps I should further explain my situation. The script that I will distribute will always make use of a very particular directory structure. In imageDir, there will always be a specifically named XML file that points to a bunch of images in the directory. However, given security checks that I put in my script, not all of those images should be publicly viewable. However, if a savvy user were to just load this XML doc up in their web browser, they will have a complete listing of URLs to all of my images. I cannot modify this XML file.

Re: [PHP] Templates
Go for a complex situation if that's what you want, or consider the basics:
home.php
?
include('inc/header_code.php');
//
// unique code for this page to be executed before the html tag
//
include('inc/header_html.php');
?
Welcome to our website!
?
include('inc/footer.php');
?
contact.php
?
include('inc/header_code.php');
//
// unique code for this page to be executed before the html tag
//
include('inc/header_html.php');
?
Contact us: [EMAIL PROTECTED]
?
include('inc/footer.php');
?
If you update any code in any of the 3 include files, you will update the
entire site's look, feel and actions. It still allows for you to execute
unique PHP code either before or after the HTML starts too.
Strip your site down to what's common, and what's unique to each page, and
see where you go from there.

That's pretty much what I'm doing today, header page, menu page, content

yeah, well a complex layout will kill it pretty quick :)
The other way is go down the route of a 'fusebox' -- one script that shows

/td
/tr
/table
/html
you can call that script with
p=contact
p=home
p=about
p=membersaction=validatestep=3favcolor=blue
And just make sure the include files do what they need to.
Here's another one, there's no way to set a cookie after the headers
have been sent, true? Any way around this at all or at that point am I
best to use session variables and/or hidden fields.
Hidden fields, yes.
You are going to have the same problem with sessions... sessions must be set
before the headers are sent too.
You need to either change the logic on your page so that you set the cookie
BEFORE the html, or enable output buffering, so that you can set the
cookie or session whenever you like, then do a flush. Personally, I've
never seen the need to use OB, because I've found a way to work that I'm
comfortable with.
eg:
?
include('header_code.inc');
if($action=='validate')
{
// validate form entry
if($error)
{ $show_form = 1; }
else
{
$show_form = 0;
// add form to DB or
// set a cookie or
// set a session or
header(Location: form.php?page=thanks);
}
}
?
html
body
?
if($show_form) { include('form.inc'); }
if($_GET['page'] == thanks) { echo thanks; }
?
/body
/html
In otherwords, I execute any code that I need to BEFORE the headers are
sent, to ensure that I CAN set cookies, sessions, or use header()... I set
some simple triggers like $show_form to decide what I want to do in the
body.
Each to their own, but it works great for me over many many applications.

Re: [PHP] restricting access to files using PHP
Assuming Apache:
1. use index.php or login.php as a log-in file, just as you are
2. if you have your heart set on naming the files .html instead of .php,
then create a .htaccess file in the dir which forces .html files thru php
for that directory
3. create a php file called access_control.php with (psuedo code) the
following contents:
---
?
if(the user isn't valid)
{
header(Location: login.php);
exit;
}
?
---
4. add ? include('access_control.php'); ? at the top of any html or php
file you wish to protect... if the user isn't valid, they will be redirected
to the login page. if they are valid, they'll see the file.
If you have lots of these HTML files to add the line to, consider a batch
process, which you can do with PHP and most text editors.
I get the feeling you could also auto-prepend access_control.php to ALL
scripts, and add a little more logic to the code:
---
?
if( (the user isn't valid) AND (eregi('.html$',$_SERVER['PHP_SELF'])) )
{
header(Location: login.php);
exit;
}
?
---

good with regexp at all!!

Re: [PHP] several buttons in form - which one was clicked
Hi,
Why do you want a checkbox beside each button? Wouldn't the button alone be
enough? I'm assuming it's for something like a delete items list?
This is one of many ways to do it... I can't see why you need checkboxes --
perhaps you need to tell us more abut what you want to achieve.
?
for($i=1;$i=30;$i++)
{
echo form action='anyfile.php' method='post';
echo Delete Item # {$i} ;
echo input type='hidden' name='item' value='{$i}' /;
echo input type='submit' name='delete' value='go' /;
echo /form;
}
?
This would create 30 go buttons, each one on it's own form, each one having
a hidden name/value of item/$i. On anyfile.php you would be concerned with
the POST var $_POST['item'] (or $item if reg globals on), and perhaps
$_POST['delete'] to know that the form was submitted.
Another option might be a list of checkboxes, and ONE go button to delete
all checked items:
form action='anyfile.php' method='post'
?
for($i=1;$i=30;$i++)
{
echo Item #{$i} ;
echo input type='checkbox' name='delete[{$i}]' value='1' /;
}
?
input type='submit' name='delete' value='delete checked items' /
On anyfile.php, you would have an array $_POST['delete'] that you could loop
through, getting the keys (id's of items to be deleted) and acting upon
them.
I could go on :)

On a major level, create or use a large CMS (content management system), and use the information you have in the databases / file system to establish what's new, modified, etc. On a smaller level, you could check which files have been updated in X days (I think) with PHP, and display them as a list, which some selective listing.

want... so instead of saying a username shouldn't contain
!@#$%^*()_+-=?:';, I say it should contain a-zA-Z0-9_-.
This means that I allow what I trust, rather than assuming I can think of
every possible bad character the user might choose.
?
// a-zA-Z0-9_ are valid in this case
if(preg_match(/^[a-zA-Z0-9_]*$/, $username))
{
// good
}
else
{
// bad
}

To answer your question, (and i've got ZERO experience with regexp's, and
the above regexp was written for me by someone on this list!) is that you
need to escape some characters, like a $ sign, with a \.

Re: [PHP] How to check for refresh in PHP
Not really that simple. You can't use the HTTP_REFERER, because it's not set when the user refreshes (at least on my browser, so at best it will be unreliable). Common ways to prevent such things happening (like voting for a pic or song or poll more than once) are usually done with either: 1. logging IP address', and ignoring two votes within a reasonable period of time from the same address -- this has a high overhead of data, and isn't failsafe, because IP address' are notoriously unreliable. 2. dropping a cookie onto the users computer, basically saying read this one, so that the vote is only counted if the cookie isn't there... obviously users can choose to block cookies, or delete them, so this isn't reliable either 3. sessions... if you maintain a site-wide session with each of your users (done with either a session id in the url, or with a cookie), you can keep track of which news items have been read on the server side with session variables. again, this isn't 100% reliable, because the user could delete the session cookie or delete the session # from the URL (both making the user appear as a new user) And that's about it. So, you've got a choice of three options, none of which are bullet proof at all. I personally like the session one (because all the user knows is that they're in a session, not that each news read is being logged), but you have to understand that you will not get it perfect, ever. I could write a PHP script, or even a client-side apple script or schedule which access' your URL every 5 mins... no cookies, no sessions, no nothin', and i'd get huge numbers :) If I was trying for the best possible outcome, I think I'd log an IP address, timestamp and user agent string (even if it's null), but rely on sessions first...

I have done this many times. You could also save the data client-side with cookies, but there's no guarantee that cookies will work on a specific client. If they want back-up/proof of doing it, then they can print the browser screen as they fill it in, AND, you can give them a confirmation page which prints all the form values back to the browser as a printable HTML page which they can either print or save as TEXT or HTML. Writing something that works offline for completion online later sounds like you're trying to make the web do something it wasn't designed for. The only solution I can think of is client-side javascript saving the form information as a browser cookie, but there's no way I'd bother, because it would require the user to have both javascript and cookies enabled, and I think there's also issues with the issuing domain of the cookie. The users are mostly in computer limbo, and if they had their way, they would want to use Word or Excel to complete the forms, save it to their hard drive and click to send it away... You can create a form inside a PDF document, and it can POST the completed data to a URL. So they could complete the form offline, print it, whatever, then connect, and hit submit. It would open a browser window with a URL like http://yourdomain.com/parseThePDFForm.php and then you would have your submitted data. Whilst not as a elegant, they COULD fill in an excel file, and upload it via a browser. Same with word. I'm not sure if wither excel or word has any method of POSTing data. With all these client-side options, there's zero hope of getting them to correct missing fields though :) Decide if this is something you want to achieve on the web, or offline. If on the web, keep it basic, with perhaps a save to server option and a printable thankyou/proof page. If offline, I think PDF forms are the best of a bad bunch.

Re: [PHP] Advice on uploaded files

Should I store the photos in a mysql database or in a directory on the hard drive? If you have experience with this any advice would be appreciated. I prefer storing them in the filesystem, and using the MySQL database to keep track of WHERE they are (link). There of course are SOME problems with that... mainly because the two are not joined at the hip... someone could accidently trash the file, or the MYSQL record, without deleting the other. Storing the image directly in MySQL has never appealed to me, because you have to do a little more work to get the image out (sending headers, having an image script, etc), and mainly because the size of the DB increases dramatically... which makes backing up more difficult/time consuming. Each to their own though :) Justin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] best way to pass variables to iframe
on 29/01/03 4:35 PM, Mantas Kriauciunas ([EMAIL PROTECTED]) wrote: I believe there was question like this, but I was wondering if someone could point me with useful information about passing variables to iframe. To point out the obvious, you can pass variables to any URL by using GET: iframe src=page.php?var1=foovar2=bah/iframe iframes can be targeted with links just like a regular frame, using target=frameName Other options would be to have variables stored in sessions, in cookies, or via POST variables (I think). But (to the best of my knowledge), since PHP is server-side, these pretty much all rely on reading/acting on the variables whilst the page is being processed and sent by the server. I get the feeling you perhaps want to have an existing page in an existing iframe react in relation to things happening elsewhere... correct? I don't think it REALLY can, since once the frame's content is server-side, it has nothing to do with PHP. You basically need to force the frame's contents to refresh, perhaps with new variables passed in with either GET, POST, sessions or Cookies. Javascript can read cookies, but I don't think this is your answer at all. You need to be more specific about what you want to achieve.

Re: [PHP] multiple entry forms !!

hi
looking for some advice
I have a site in progress. user to it have to enter a LOT of information (it
will contain a club directory)
in order to try and make it a less unpleasant experience for the user, I
want to give them 7 smaller input forms, each one following the other
what would be the correct way to do this, one very large, complex coded php
conditional form that does everything, or several smaller ones ?
one script to run the form with decent logic to break it up into a few
sections... but that's makes reading/updating the script difficult, so I
prefer to include() the HTML code for each form, and in some cases, eve
include() the main programming for each section
if I use one form, it will conatin rather a lot of code, but execution would
all be handled by the form itself
but if I use multiple smaller forms, each form would need to process the
previous forms input, and then display it's inputs for entry
I am also using sessions, which adds a little to complexity
actually, they help!! You can save the contents of form1 into the session
before showing form2, then adding the contents of form2 before showing
form3, etc etc. Much easier than setting cookies, writing hidden inputs on
subsequent forms, etc etc.
any general good coding practice tips/links would be helpful
Use $_GET variables to keep track of which part of the form you are upto,
and what you are doing.
I'd suggest this is a lot clearer than reyling on $_POST['submit'] being
true or anything else like that.
So, maybe you have a few status':
- status=showForm
- status=validate
And for both modes, you would tell the script which form part to
show/validate using a GET variable formPart (=1,=2, etc)
So when the script first loads, set a default of status=showForm and a
formPart=1
?
session_start();
// $status
if(isset($_GET['status'])) { $status = $_GET['status']; }
else { $status = 'showForm'; }
// $formPart
if(isset($_GET['formPart'])) { $formPart = $_GET['formPart']; }
else { $formPart = 1; }
?
Then BEFORE anything is sent to the browser, validating would usually take
place, so that you can do any redirects or anything like that. The way I've
set it up, is that each form part has it's own php script with some code to
validate the form entry.
?
if($status == validate)
{
// look for an include file which matches the current $formPart
// and include it... haven't put in place an error checking
$validateCodeFile = inc/validateFormCode/{$formPart}.php;
if(file_exists($validateCodeFile))
{
include($validateCodeFile);
}
}
?
I'll show a sample of these include files later. The aim of MY include
files is to return a var $validEntry of true or false... based on that, I
can decide whether to add the form contents to the session / database, or
whether I should show the form again, due to errors.
?
if($validEntry)
{
// either add form contents to session or to database
//
//
// redirect to status=showFormformPart=[next]
$next = $formPart + 1;
header(Location: myscript.php?status=showFormformPart={$next});
}
else
{
// show same form again with error message
$message = you screwed up;
header(Location:
myscript.php?status=showFormformPart={$formPart}message={$message});
}
?
That (roughly) takes care of validating each form entry, keeping track of
all the vars with sessions or adding to a DB, and passing people onto the
next form part.
Then you'd want a few lines of HTML, then some code to show the right
formPart's HTML code, and a few lines to clode off the HTML.
if($status = 'showForm')
{
?
html
headtitleform/title/head
body
?
$includeFormCode = inc/forms/{$formPart}.php;
if(file_exists($includeFormCode))
{
include($includeFormCode);
}
?
/body
/html
?
}
?
The secret is that we're using include files to make sure the form's code
base isn't messy.
The whole script in one:
---
?
session_start();
// $status
if(isset($_GET['status'])) { $status = $_GET['status']; }
else { $status = 'showForm'; }
// $formPart
if(isset($_GET['formPart'])) { $formPart = $_GET['formPart']; }
else { $formPart = 1; }
if($status == validate)
{
// look for an include file which matches the current $formPart
// and include it... haven't put in place an error checking
$validateCodeFile = inc/validateFormCode/{$formPart}.php;
if(file_exists($validateCodeFile))
{
include($validateCodeFile);
}
if($validEntry)
{
// either add form contents to session or to database
//
//
// redirect to status=showFormformPart=[next]
$next = $formPart + 1;
header(Location: myscript.php?status=showFormformPart={$next});
}
else
{
// show same form again with error message
$message = you screwed up;
Re: [PHP] PHP Page Refresh on Redirection

I have a PHP page with a form that submits to another PHP processing page.
On completion of the PHP actions on the processing page, I have echoed into
the page the javascript action of 'location.href=...' and the location is
redirected to the PHP form page that starting the process. Both pages take
data from an SQL server. The problem I'm having is that the the javascript
always grabs the cached page. I need a newly refreshed page to return with
updated data from the SQL server. Any suggestions?
In addition to sending the correct no-cache headers (which don't always work
with certain browsers and clients), you could also attach a random string to
the URL as a GET variable, so that the browser thinks it's a NEW, unread
URL.
include this function (straight from the manual) via a function library:
?
function make_seed() {
list($usec, $sec) = explode(' ', microtime());
return (float) $sec + ((float) $usec * 10);
}
?
Then to get a random number,
?
// seed the rand no generator and get a rand value
srand(make_seed());
$randval = rand();
?
Then you can echo it as a get var or querystring on any URL:
location.href = page.php?r=?=$randval?
location.href = page.php??=$randval?
