[PHP-DB] values across functions
I have a file, it's a shopping cart. Currently is contains all the fuctions required in the cart, including the shipping and billing form. It won't take the values from the shipping form and use them in the functions that calculate the tax and S H. Why would this be? I've gotten other variables to transfer, just not these.

[PHP-DB] PHP amd MYSQL
I am setting up a web page system which involves html pages, php pages and mysqldatabase. I have a number of questions and do not know where to find answers. If I display the rows from a database table in a php generated html table is it possible to mark a row so that it can be deleted or modified by calling another php page? If so is this documented anywhere? Is there any good source of information on setting up 'forms'to work like Oracle forms where database records can be inserted, updated or deleted?

I'll add this snippet in to prevent accidental deletes:

you really want to delete this record?\)' ' . $row[name] . '/a

This would set up a url that when the user clicks on $row[name] (such
as
Record Description it would call delete.php with the argument of
$row[id]
Within that delete.php, you remove the selected record, then call the
original page.
Use:
$sql=DELETE from table where id=$id;
Then do:
echo '
Header(Location: original_location.php);
You can't have any html previous to the Header command, though.
This will return you to your original page where you can do your select
again, and the deleted row won't show up.
You may need to pass parameters on the Header line to let
original_location.php exactly where you were previously. This would
have to
be passed either on the url or as a post/get operation when first
calling
delete.php

Re: [PHP-DB] permissions system
Very simply I protect whole pages on my member's website by include()'ing a
script called auth.php into the top of each page. Rather than using a
binary string to turn functions 'on' and 'off', I do things a bit more
general than that. I have defined levels of access (ie, L1, L2, L3, etc..)
stored in the member's table in the database. At the top of each page I
wish to protect I write ($min_access = 'L2') to define a minimum level of
access. If the user has L2 access or greater they'll fall right through the
auth.php and end up on the page. Otherwise one of the conditionals will
catch them like a net and dump them into the logout() function which kills
the session and displays the login screen with a lovely ACCESS DENIED (or
other appropriate text) message. In this way I can protect any number and
type of webpage (so long as I rename it .php) without registering the
filename. And all of my staff and admin scripts can remain public instead
of behind some .htaccess file.
As for the complexity of auth.php. It's hardly complex but I'm fairly
thurough in my check. The auth.php script is actually about 150 lines of
code and does timeout, tracks the member's movement and more... but it
could be as simple as a single db query. This is the best continuous
pervasive authentication scheme I have devised. It's probably not as good
as other systems out there but it does the job in the limited scope of
protecting my member's site. :)

Subject: [PHP-DB] permissions system
Howdy All-
I've poked around the net for some snippets, and have done my own in the
past,
but wanted to get some more ideas on how you do a permissions system.
This
means, in your application, how do you control and enforce different
permissions for different users?
Simple example: An image repository. You have users who can download
images
and/or upload images. And certain users can only search for images within
a
certain criteria.
What I've done in the past is created a permission_flag column for each
user.
Zero or One determines whether or not the user can do that function, and
the
various functions are indicated by position (or index). So if you had
upload
and download functions, you can have:
01 = can download, but can't upload
11 = can download and upload.
If I add a new function, I have to add another digit (and potentially
increase
the column size if things grow faster than planned).
To enforce this, as a user attempts each function, I simply check the
function
index and see if it's one or zero.
With me so far?
Now, for restricting database access:
What I've done is created a user_where column for each user. In this
column I
add a where clause that's appended to each and every search the user
attempts
(with the usual input safety checks for common db exploits).
For example, if a user can only see Approved images (in my pretend
application
example here), the user_where value might be category = 'Approved'. For
multiple values, it could be category IN ('Approved', 'Pending').
Does this make sense? How are other people doing things? I've given a
little
bit of thought to it, but not enough. With all the applications out there
everyone at some point has to come up with their own system.
Ideas?
Thanks,
Jason

Re: [PHP-DB] PHP amd MYSQL
Hi, I am setting up a web page system which involves html pages, php pages and mysqldatabase. I have a number of questions and do not know where to find answers. If I display the rows from a database table in a php generated html table is it possible to mark a row so that it can be deleted or modified by calling another php page? I dont know if mysql supports select for update, but the locking will not work. The reasons are: As soon the PHP page ends, PHP will realease all non persistent database connections.You can work around this, using a persistent connection( this type of connection doesnt close even after the php script ends ), but this kind of connection can bring you troubles. You will get troubles if you run insert or update commands, because all script instances will share the same database connection. If for some reason, a script( or the db server ) locks the table for some reason, all scripts that use the persistent connection will wait for the unlock of the table.Worse, if you rollback a transaction, every transactions that use the persistent connection will be roolbacked. Is there any reason to lock the rows? If so is this documented anywhere? Is there any good source of information on setting up 'forms'to work like Oracle forms where database records can be inserted, updated or deleted? I dont know. Sorry.

[PHP-DB] not a problem per se, just a curiosity.
I have have developed a statistics package that tracks user info(browser, os, colors, heights, widths etc) as well as where and when they use my various sites. in the tables there are about 40 hits of aproximately 7,000 that the broswer entry is PHP/2.0 and PHP/1.2 only. Normally an entry looks like - Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.4) Gecko/20011128 Netscape6/6.2.1, but these are just PHP/2.0 for example The IP address it inserts is the address of the server itself. It does not look to be a misreprensted browser as it never accepts a cookie showing itself as a return visitor(internal site, all our browsers accept cookies) Anyone have any idea to how this info gets in there. It has hit different pages, and is not a daily entry or anything that would lend itself to a hint. as i said in the subject - not a problem per se, just a curiosity. Be well all, Jd ps. I have this same package on external www sites, and this entry never shows. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP-DB] values across functions
have you declared the variables as global int eh function?
eg
function foo($bar) {
global $this, $that, $theOther;
[...]
}
that way $this, $that and $theOther variables are available everywhere

May 29, 2002 isn't a MySQL timestamp, so I'm guessing you have a textual field type. The lesson of all this is: Convert dates to either unix or database-native date format before storing them in the database. Things like May 29, 2002 are useless in a database. At this point I'd recommend running a quick script to strtotime() all your dates and then re-write them to a new field that's in a proper format. miguel -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
