Re: [Phplib-users] session4_custom.inc

[Dennis G. <ge...@cv...>]

Thank you, Marko.
	session4_custom extends the class Session which is in session4.inc, as far as I 
know.
	What do you actually use sessions for? This is is the first time I have had 
sessions going.

[Phplib-users] templates and regexp in oohforms ?

[Ernest B. <Er...@Be...>]

Hi there, I am using templates and oohforms together, which causes a 
problem if a validation regexp is beiing used. 
"valid_regex"=>"^[a-z]{5,}$". The "{5,} string gets parsed as a TEMPLATE 
variable. Is there a solution to this if i do NOT want do set the 
templates to "keep"?



PS: is that my ilusion or had the oohforms->validate() returned an 
associative array in form array("elementname"=>"errormsg") ? Now i use 
the newest 7.4pre2 and only a string is being returned.

PS2: the files from CVS looks VERY different, is anywhere a upgrade info ?

ohhh, sorry maxim, thanks for the hint, I forget myself sometimes. I
should better check what I post here... :(

Of course, what I remembered was the status before you changed over to
extending the session4 class. Now, of course, session_custom is a child
class of session4...

SORRY for my misleading comment!

session4[_custom] was refactored about 2 years ago :) custom depends

[Phplib-users] re:[PHP] native vs. phplib sessions

[Dennis G. <ge...@cv...>]

Well, I said that I'd report.

Using PHP4 Native Session framework,
PHPLIB,
and PHPLIB database container functionality works great!

I only have one concern, and I don't know where the issue lies. If a sesson is 
not listed in the database, i.e., i've deleted it, a revisiting browser's cookie 
session gets installed in the DB, i.e. accepted.

There's new code in the PHPLIB library to prevent this using GET, but mabye 
nothing for cookie session 'freelance' creation. It might be the way PHP4 Native 
Sessions are doing it?

PHPLIB is getting long in the tooth, (old), but works pretty well. I think it 
should be written to be more object oriented and easily configured,

	https://sourceforge.net/mailarchive/forum.php?thread_id=1942848&forum_id=808

but for now, it's fine.

[Phplib-users] cookie vs get

[Dennis G. <ge...@cv...>]

There's new code that prevents users from using the GET functionality to create 
sessions on the site using PHPLIB.

Well, Using:
	session4.inc
	custom_session4.inc

I created a session on my browser. Then I went to the database and deleted all 
the sessions. I then reloaded the browser and the session reappeared in the 
database.

So, does this mean someone using a terminal program or other program who is 
capable of handwriting an HTML exchange, could craft a cookie session and have 
it be accepted?

If this is true, that means:
	Creating a GET session can't be done,
	Createing a COOKIE session CAN be done?

Also, I don't know if this is the fault of PHPLIB, or the PHP4 Native sessions.

[Phplib-users] change of parameter location

[Dennis G. <ge...@cv...>]

right now, as I see it,

the following things have to be done to configure PHPLIB:
-----------------------------------------------------------
1/ Extend any classes.
2/ Put them in the prepend file
3/ Alternatively, put the extensions in local
4/ In the session class hand write in the container class.
5/ In the open page statment, give the extended class names.



If it were being redone from scratch, I'd do it like this:
----------------------------------------------------------
1/ Make page an object, call it phplib_page, in phplib_page.class.php.

2/ Do away with local, prepend, page files, (phplib_page.php would take their place)

3/ Create a global array called $PHPLIBCFG at the top of phplib_page.class.php
with slots,
	's' => array( 'file'=>'session.inc' , 'class'=>'Session' ),
	'u' => array( 'file'=>'user.inc',     'class'=>'User' ),
	'a' => array( 'file'=>'auth.inc',     'class'=>'Auth' ),
	'p' => array( 'file'=>'perm.inc',     'class'=>'Permission' ),
and possibley I would also make the user/auth/perm be a form of phpgacl, (look 
it up on web)

4/ Use separate files for extending each of the class types,
sess/user/auth/perm.

6/ to use the library, however it was configured, would be simple, just
include	'phplib_page.class.php' or the file for whatever class you had for 
extending phplib_page. Pass a string for whatever functinality you wanted in the 
application, i.e. 's', 'u', 'a', 'p'. So if I wanted sessions only, I'd create 
an instance:
	$my_page = new phplib_page( 's' );
for session and user variables,
	$my_page = new phplib_page( 'su' );
etc.

7/ The constructor would assign references to instantiations of 
sess/user/auth/perm objects to class/object variables. Then it would assign 
class functions to the PHP native session handlers.

8/ All public functions would return either TRUE, or an error string. NO output 
would go to the screen.

[Phplib-users] session4_custom.inc

[Dennis G. <ge...@cv...>]

anyone using session4_custom.inc?

I see a line in the file session4.inc where it says to make sure to call the 
constructor from extending classes, but session4_custom DOES NOT call it with 
its constructor.

Also, I'd like hear experiences people have had with this.

[Phplib-users] question about php4 sessions

[Dennis G. <ge...@cv...>]

Does PHPLIB7.4.pre2 or later with <session4.inc> use the databases to store 
things, or the local filesystem method that comes with PHP4.xx.xx ?

Does selecting which storage container, i.e. ct_sql.inc, affect where sessions 
get stored in PHPLIB7.4.pre2 or later?

I have read:

<using php4 native session handlers>

	http://www.php.net/manual/en/ref.session.php

<using php4 sessions with custome session handlers>

	http://www.php.net/manual/en/function.session-set-save-handler.php


There are LOTS of quirks compared to PHPLIB sessions. I'd like to use PHPLIB's 
datbase storage of sessions with the PHP4.xx.xx session system, and NOT put the 
sessions in the file system, this is why I ask the questions above.

Ah!  Okay, I see now.  The code snippet I posted before is not what was

anything with the data but, that generally stops working when you comment 
it out ...  I guess that will teach me to code into the wee hours without

Thank you for your patience.

Then why is $db->seek() throwing an error?

There is nothing in the DB class which calls that method.
So I assume your code is calling it.

No, that is incorrect. If there is no error the class won't report one.

Okay.  Thank you for the suggestion.

I am already checking to make sure the result set is non-empty before I do 
anything with the results.  That is not a problem.  However, the default 
behavior for phplib is to display an error message for the query that is 
"performed without error."  Unless I turn that off, the user will see an 
error message where there is no real error.  If I do turn it off to avoid 
that, there will be no error message displayed if something else goes wrong ...

So, out of the box, phplib will either display an error for a non-error 
condition or the programmer must write an error handling routine and turn 
off phplib's built-in error reporting.  Admittedly, this is probably an 
uncommon scenario but, best I can tell, there is either a bug in phplib 
(for displaying an error message when there is no error) or a documentation 
oversight (for not specifying that the programmer must write an error 
handling routine.)

Again, not a huge problem.  I just wanted to be sure I wasn't missing 
something more subtle.

That query is performed without error. It just returns no results.

Check $db->num_rows() to make sure you have some results before
you start working with them.

[Phplib-users] DB Error Reporting Broken?

[Andrew C. <An...@Ev...>]

Greetings,

Do the SQL error reporting functions not work or am I misunderstanding 
something?

If I run this snippet of code:

>$db = new DB_Example;
>$db->Halt_On_Error = "report";
>$query = "SELECT * FROM emptytable";
>$db->query($query);
>echo "Error = " . $db->Error . "<p />\n"; //debugging
>echo "Errno = " . $db->Errno . "<p />\n"; //debugging

... when emptytable contains no data, I get this output:

>Error =
>
>Errno = 0
>
>Database error: seek(0) failed: result has 0 rows.
>MySQL Error: 0 ()

Based on the docs, it seems like $db->error should contain "Database error: 
seek(0) failed: result has 0 rows" or some subset of that.

The output for the scripts I am writing is all templated.  I would really 
like to be able to turn off the default error messages (the "Database 
error: seek(0) failed ...," etc.,) which display unattractively at the top 
of the page, and output them as an error message within the page.

I know I can turn off Halt_On_Error completely but, since $db->Error is 
empty and $db->Errno is 0, regardless of what happens, that eliminates any 
indication of an error state.  It's not a big deal with this particular 
error but, I worry that turning off error reporting completely will cause 
me to miss more important errors.

You need to remove the quotes in the call to MyFunction_validiator.  At

Hi,

some while ago I came across the problem of saving an array var together
with it's actual position pointer. When the session vars get saved in the

__wakeup methods)?
