Any thoughts?  Comments?  RTFM suggestions?
You may want to try this cache class. You can take any variable and 
serialize it so it can be stored for later retrieval without querying 
your database.

http://www.phpclasses.org/filecacheclass

Usually I do not recommend caching just variables. For instance, if your 
variables will be used to generate portions of HTML pages, it would be 
more efficient to cache those portions of HTML data instead of the 
variables that is only used to regenerate such HTML data.

You might have some sort of error message disabled in php.ini.  If you just 
copy and paste from that html file, it's riddled with invalid characters.  
You'll have to manually go through the copied source and replace all of the 
spaces and newlines.

Re: [PHP] Forms & Session variables

You need to slow down and think things through.  My recommendation would be
to get a SINGLE PAGE form to work how you want first, then assess the logic
needed to move onto multiple forms.

Also, this was asked a while back, so here was my answer & sample code last
time:

[PHP] Forms & Session variables

2003-03-10 Thread Ashley M. Kirchner

   I'm trying to build a multi-step form and using sessions to register 
the field values, but having serious issues.  This is what I'd like to do:

   step 1 (first page): ask for name, address, email. [submit]
   step 2 (second page): ask for more personal information [submit]
   step 3 (last page): ask for specific event information [submit]
   send everything to a back end MySQL db, and redirect to a thank you 
page.

   This whole process is just one form.php file that posts to a 
process.php script.  The content of form.php gets changed based on the 
step# (they get included step1.inc, step2.inc, and step3.inc.)

   However, after each [submit] I would like to verify the data prior 
to continuing to the next page.  If any of the fields are missing or 
incorrect, we re-post the same page with the correct fields already 
filled in (based on whatever the user entered), and the missing one ... 
blank (obviously.)  But, if everything is okay, and all fields check 
out, register the values and go on to the next page.  Repeat the process.

   I'm having a heck of a time with the validation part.  Either things 
don't register, or it gets stuck in a loop, regardless of what I change 
after the re-post.  So, I need some help.  I need some code...help!

I get the same thing so I'm working through it. But here are some ideas that
may work for you: What are the permissions of the file in question? And do
you know the exact path of the file? Also, is the first line above (line
29?) needed? Why not just use $feed as the filename?
Forgot to mention this. Pulling via http. Works in the browser, but not in 
the script. The line above is needed, but it has nothing to do with fopen. 
Using url instead of $file produces same error.

filesize() won't work on remote files (through http) and like Justin

[PHP] Re: Persistent values between executions

2003-03-10 Thread Mike Mannakee

Yeah, it's on linux.  I had a similar thought.  I figured, if no other
solutions came from the post, I could hard code the variables into a file,
and if I needed to update it, make it self updating.  Like do a string
replace to add the new variables I need in the include file itself.  Bit of
a pain, but once it's running it should be alright.

Note that your session files will never be cleaned up if you use
session_save_path(), unless you do it yourself. This means that a file
will be created each time someone comes to your site and it won't be
erased. Only the path specified in php.ini will be cleaned up... which
is what you want.

file.  Then, have a cron job run that script however often you need to have 
those variables updated.

Another way you could do it is initialize the variables you need as session 
variables if the user logs in (assuming you're using an authentication 
system), which will stay active as long as the user has a valid session.

Is your session.save_path set to /tmp? It's my understanding that you should
specify a directory for saving session data -- or use a database -- that
/tmp is subject to garbage collection, and specifying a directory prevents
that. I made this change to a site recently. In tests prior to the change
the session would last up to about 2.5 hours with no activity. After
specifying a directory with session_save_path() right before
session_start(), the session was still OK after almost 4 hours of
inactivity. (Not much of a controlled test, I admit.)

That said, here's a disturbing fact that turned up last week -- a designer
working on the same site was continually being logged off unexpectedly.
After many tests he identified that the problem was Microsoft IE/Entourage.
Every time he checks email he's no longer recognized as logged in (Mac OSX
IE). He got Microsoft tech support to duplicate the behavior and confirm
it's a problem with IE -- doesn't happen with Mozilla.

So, it's important to verify the problem with more than one system, but it
sounds like you have since you mention both IE6 and IE Mac!

Re: [PHP] Re: sessions terminating randomly please help

Check if your server is using files or shared memory to save the sessions...
My ISP was using mm (memory), and it was buggy... when they changed back to
files, all was well.

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.

HTTP_REFERER (is that the right spelling?) is set by the browser, not
the server. So if you're not seeing a value, then your browser is not
setting it. Or something is stripping it on the way out from your
computer.

Well, if the site doesn't return the number back to you, then you can't
do it with the method you're using. You could use sockets or cURL to
POST the info yourself from within a script and then you'd still
maintain all of the $_POST information when you get the result back...

I checked the manual. From the example, it is apparently that timeout only 
works for the handle setup by fsockopen, but not for fsockopen itself.

You can't control the timeout with fopen(). Try looking at fsockopen().

[PHP] How to set a timeout limit for a call of a connection?

2003-03-10 Thread Alex Shi

Hi,

I have a script in which there is a call to open a remote file:

fopen ("http://www.somewhere.com/file.php?foo=bar";, "r");

Sometimes if www.somewhere.com is down, it will stuck at the function
for very long a time. I hope to setup a timeout limit for this function
(just
this), so that it won't stay very long to wait for a result, but just quit
if the
call take a time longer than timeout limit, and then go on for next steps.

Thanks in advance!

RE: [PHP] PHP Online Store



Hi Pag,

In my experience, I usually have two database systems.
I have the Live DB which is currently the one used 
by the website which is the one on the hosting server, 
and I also have a local DB on our local server just here.

What I do is I create the back-end applications for the
administration of records, like add, edit, and delete.

The idea is that for a certain time of day or perhaps
weekly, it depends on your need... these two databases
should be synchronized...  meaning their records be
reconciled... Most often in my case it's a one-way 
direction.  

Records from your local database will be sent to the
live server either for addition or just updating some
fields... As a hint: you can just add a field if 
you'll either ADD or just EDIT a record in the live
database... or you can issue a SELECT query and then
if it exists.. you can either interpret it as a
condition for ADD, else, EDIT..  It depends on your
system.

On doing the syncs, you can create just a PHP script
to send data (i.e. CSV) to the server.. you can
use fopen("http://www";) or perhaps just use the
POST and GET Methods.  The recieving script on your
live server will parse and do the necessary actions
for your data.

Furthermore, you could add your PHP script to your
CRON (*nix systems) if you want to create a schedule
for your sync times.  (say 12:00 Midnight when no 
one is around in your office) :)  Or you can do
another workaround in your OS. Otherwise, just
run the script manually. ;)  Watch out for expiration
limits too...  as you may have large data to send. :)


Hope this helps,

Miches

Hi,

I have to write a PHP/MySQL online store with product catalogs, prices,
descriptions, and ordering (no payment) etc, but i have a big doubt when it
comes to updating.
How is it usually done? I mean, i never did a project like this, with a
big amount of products to update. Whats the easiest way of updating the
prices like say, every week? The suppliers send a list of the new prices to
the store, and the store has to update the prices online manually, one by one?
Also i thought of saving the excel file in csv format and uploading to the
site, where some sort of parser would collect the new info from it. The

Hi,

You can read the file via fopen() and fread(),
and then pass the resulting data to the client browser...

Hi,

I'm developing a flash site that uses PHP and MySQL to pull in images.
My client would like to have a button in flash underneath the images he
has shown that would enable the viewer to download the images to their
own harddrive.

I know I could set it up to open the picture in a new window and have
the viewer 'right' click on it and select Save.  But is there anyway to
automate this so that Flash would open the URL that would automatically
open the "Save Picture" window for saving to the person's harddrive?

Thanks,

[PHP] .htaccess Help

2003-03-10 Thread Pushpinder Singh Garcha

Hello All

I need to allow users to be able to access ONLY non-html files in a 
Secret Dir.
Can anyone suggest a .htaccess method to do just that.

I have a .htaccess script which will prevent anybody from viewing the 
contents of a Dir via http, but this time , I need to allow users to 
view the PHP Files

[PHP] PHP Online Store

2003-03-10 Thread Pag

	Hi,

I have to write a PHP/MySQL online store with product catalogs, prices,
descriptions, and ordering (no payment) etc, but i have a big doubt when it
comes to updating.
How is it usually done? I mean, i never did a project like this, with a
big amount of products to update. Whats the easiest way of updating the
prices like say, every week? The suppliers send a list of the new prices to
the store, and the store has to update the prices online manually, one by one?
Also i thought of saving the excel file in csv format and uploading to the
site, where some sort of parser would collect the new info from it. The
problem with that approach would be if the supplier changes a cel on some
product name, then everything would be ruined.
How is it usually done?
	Big thanks, i am completely blind in this.

RE: [PHP] Help Needed

I agree with the security on files especially on case 
of downloadable files.

I suggest you use absolute paths for retrieving your files.

say ( http://www.a.com/pathofyourfile/ or 
simply the platform /home/user/htdocs/files/pathtoyourfile/)

Also, it's neat to have sorta config file on your scripts
to maintain the directory paths.

But oops, I maybe over acting here:)))

Yet, I'm sorry I'm not familiar with the MacOS Jag Platform,
but perhaps PNG files aren't compatible on that machine.

RE: [PHP] auto_increment $value

I think this is facing a bigger issue when it comes to 
Concurrency. When two or more apps in a given time pops
the auto_increment or mysql_insert_id (they will get 
THE SAME ID assuming no other transaction issued an 
INSERT sql to the table while retrieving the ID).

Now, I don't know if this has a major effect on your
applications but when your programs get bigger and
larger... basing algos on things like this just won't 
work.   

Just be very careful though.

Miches:)

This won't work anyway since your class test is declared after using it -
it should be the other way 'round:

Re: [PHP] ob_start -- output buffer problem

2003-03-10 Thread Jim Lucas

because the flush happens after everything is done, including the fputs
thingy.

you have to call ob_get_contents() or something like that.

I always to this

ob_start();

do something

$data = ob_get_contents();
ob_end_clean();

then I work with the $data later.

but if you don't use the ob_get_contents(); or ob_end_clean();  then PHP
waits until everything is done, and then flushes.

RE: [PHP] Re: sessions terminating randomly please help

Assuming that php is configued to rewrite the url tags, try turning off
cokkies in the browser and let the Session if carry over. This might help
you debugg 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  and sometimes it's explicit, as 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().'';) and see if it
changes at any point, and especially on the pages that fail.

RE: [PHP] sessions terminating randomly please help

2003-03-10 Thread Dennis Cole

Make sure that the url is always the same. For example if a user is at a
page http://mysite.com/phpscript.php and you link to
http://www.mysite.com/phpscript.php (notice the www) the session might not
follow because the url is different.

hi

arrive at a page that tells me that i'm not logged in anymore. this happens
apparently randomly. i have seen it on ie6, ie for mac, netscape 4.7 for pc,

the apps are hosted on

i can't go into production if there's the possibility that users will be

don't think i can attribute this to a miscoding:

when a user logs in, i create a session with

i have the following code at the top of each page to check to see if the

is valid:

i have a logout page that destroys the session

session_destroy();

i also have a javascript timer in the header of every page that redirects to
the
logout page if the user has been inactive for 20 minutes.

i have played around with session.gc_probability, setting it to 100, but

this is a huge problem.

2003-03-10 Thread Dan Phiffer

I believe there's a domain limitation inherent to the way cookies work
(assuming a cookies-based sessions setup), but there may be some way of
circumventing that (can't some ad banner companies track visitors from site
to site?). Seems like a multi-file search and replace should do the trick.
If you're using UltraEdit/BBEdit/Emacs you should be able to update your
links without too much effort.

If they use a proxy that doesn't send HTTP_REFERER, It'll break things. 
My numbers say it happens about about 15% of the time:

mysql> select count(*) from hit where urlid=0;
+--+
| count(*) |

|83082 |
+--+
1 row in set (0.53 sec)

mysql> select count(*) from hit;

1 row in set (0.00 sec)


Since you don't want to use sessions, maybe 401 WWW-authenticate method
would work better for your application.

That is a good question...  I've had the (privelege?) of working with php
almost exclusively for the past 3-4 years, to the point where I've rarely

[PHP] Sessions problem

2003-03-10 Thread David Chamberlin

Hey all,

Some of my users have reported a problem with my site and it's taken a 
while to debug it, but I think I've finally tracked it down.

If they go to the site as:

http://www.mysite.org/

Then it works

But if they go as:

http://mysite.org/

It doesn't.

I believe it has to do with my use of session variables.  Apparently (I 
didn't know this, but it's obvious from the debugging) that there are 
different session ID's and thus different session variables for the two. 
  And the problem is (due to sloppy programming on my part ... sigh 
...) that sometimes I set up the links as  and 
sometimes I do the explicit http://www.mysite.org/">.  So 
when it goes to the link as www.mysite.org, it registers the variables, 
but then later when it tries to access and it's just mysite.org, the 
variables aren't set.  Lots of confusion ensues.

Is there any way to unify this, or do I have to go through and fix all 
of the absolute links to be relative?

Thanks,

Hehe, yeah I am being somewhat anal here. I was hoping that with
search-friendly URLS (i.e. /issues/2003/mar/ rather than
/issues.php?year=2003&month=mar), I could have the added security benefit of
obscuring the back-end technology. This is more from the theoretical than
practical line of thinking, so I'm not too worried.

While I agree that if the app is well-written it shouldn't matter, but I
figure it couldn't hurt as an added security net. I have another question
reguarding the security implications of "source readable" PHP projects, but
I'll save that for another thread.

I guess this question was coming from a "couldn't they have designed in a
cleaner way?" perspective. Don't get me wrong, I think the way PHP does an
outstanding job of handling these particular kinds of form submissions, I
just figured there might be an alternative syntax.

Just my humble opinion, of course, but I think you did the job quickly
considering what you were given to start with. $40/hour is pretty cheap,
too.

No one likes paying and it always seems like a "little change" to those on
the outside.

It would of been hard to nail down a contract given the circumstances, but
that's what you should have done. Always get it in writing. If you agreed on
$40/hour before hand without a "maximum" number of hours where you had to
get back to them, then they have to pay.

Re: [PHP] quick question

2003-03-10 Thread Doug Parker

Right - but the problem is, the form is submitting to another site, so i 
don't have a way to store the variables.   I could put them in session 
variables, but I would have to create another script and then forward 
the form submission to the outside side.  This isn't working because the 
 outside site requires the variables to be submitted via a form, or 
POST i guess.  I don't even know if I'm going about this the right way - 
I just need to somehow store variables on my site that are submitted for 
processing to another site, so that when the user is sent back from that 
other site, i can put the values in the form fields of a new page.

can i do this?
So put the value in the "value" attribute of your text box.



substitute $_POST['cc_number'] with whatever you send to the processing
site.

[PHP] A question of time...

2003-03-10 Thread Robert Cummings

Hi all,

I recently had a freelancing experience that has left me somewhat sour and
questioning myself. Unfortunately I don't feel I can fairly evaluate myself
and so I owuld like to put the question to my peers who populate the PHP
forum as to whether I have performed competently.

Last week I took upon myself the task of fixing a clients shopping cart
system by way of adding session support and proper user registration
validation. To give you some idea of the parameters of the job...

- VNC development connection
- live server with no error output
- no session support whatsoever
- cart had no input validation, except basic javascript
- user registration permitted clobbering of other users
  and had no validation either
- PHP code was ad-hoc sprinkled through the pages
- comments were almost non-existent

The first day I decided it would be best to mirror the server so that
development time would be minimized (VNC is terrible for devlopment). This was
done without charge to the client despite it's time saving effect.

The second day I spent 13 hours familiarizing myself with their code and
pages, and on this day I also implemented a session management library for
easily accessing and setting session data (this included hooks for permanent
cookie data storage). I also fixed the user registration process and add
security validation to ensure user information could not accidentally (or
deliberately via form hacking) be accessed by someone other than the
registrant. Previously re-registration of an existing email address regardless
of password would clobber existing customer. At this time I also fixed the
cart and ensured prepopulation of forms for updating registration information.

The third day I first wasted an hour making my changes work on their
server because they decided to rename all the files I had changed thus
breaking all of the include() paths. After that I spent another 3 hours adding
support for returning to previous page before entering any of the cart
checkout or customer registration pages. At this time a response page was also
added to thank the customer for their purchase. Of course all of this was
tested to be functional and where necessary broken pre-existing code was
replaced or fixed to provide the correct functionality.

On the fourth day I spent 3 hours adding support for input validation
feedback to the registration validation so that customer's would know exactly
why they could not continue. I also added support for a password reminder to
inform the user of their password when forgotten. This included adding the
page, adding the form, validating that the user id existed and outputting
appropriate feedback if the user did not exist - and of course testing.

All in all I spent 20 hours total for the client at a rate of $40 USD/hr
which I believe is on the low end of freelance. I myself have 3 years
experience devloping PHP web applications. So the question I ask is whther
this time frame is reasonable, or am I just a slow crappy programmer that is
ripping these people off? They seem to think I should have had this done in
just a few hours, but my experience thus far indicates to me that they got
just service. Additionally it seems before I took the job, they had went
through several other PHP developers would said they couldn't do it (and I
don't really blame them considering the VNC connection and lack of comments or
error feedback).

If it turns out that I am incompetent, then I will happily send them a
bill for zero hours, otherwise I would like to take comfort that I am not
ripping them off.

Sincerely,
Robert Cummings

Re: [PHP] image question

Tony,
You might want to try the online php manual, I hear it's very good.
You should be able to do all of the tasks you desire.  Look for "image" in
your search.
Hope this helps.

Thanks for the reply Mark,

allow_url_fopen is set to on

It sounds like either allow_url_fopen is set to false or php was compiled
with --disable-url-fopen-wrapper.  Either way, checking the output of
phpinfo() should give you your answer.

That's because we do not support a static build for Apache2.
