[PHP-DB] Re: permissions system
I've heard a couple of ideas, but so far nothing very different from what I'm
planning. Has anyone done anything really different out there?
Kevin, I like your idea for quickly protecting several pages. The difference
here is that I need to be able to turn on any combination of access for users.
By using Levels, it doesn't give me quite the granularity of permissions for
this particular project.
Come on, let's see some creative solutions! I know there's some pretty dang
smart people out there, and this isn't a new problem. I'm also starting to
dissect some existing open source projects that have multiple users and
permissions to get (hopefully) some other ideas.
Thanks for any thoughts!
Jason

Subject: 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

[PHP-DB] problem with mysql_query
Hi,
I've a problem with the following script. Sometimes it does write the

RE: [PHP-DB] CSV/TXT file imported via PHP into MySQL
Keiran,
in your second page, you refer to $textfile as the thing that you want to
load into the database; this file doesn't exist on the server, so it is
inserting nothing I would imagine.
You need to use something like $_FILES['tmp_name'] to refer to the actual
file, once it has been successfully uploaded to your server

[PHP-DB] Having trouble understanding how to manage arrays
Hi all. I am very new to this, and have been reading my way through php, but have
come accross a stumbling block that I just don't seem able to get past, although I'm
sure it's something simple.
I have a very basic mysql database set up, that contains a table with 4 fields- type,
manname, manlink, and recordno
What I need to do is pull all records from the database, and provide a list on a page
with links to the url's stored in manlink with the lable manname. So far, I've come
up with the script at the end of this message. This script works beautifully for me-
for the first record. Could anyone point out why it won't go on to any other records?
Thanks,
Newbie Bill
?php
/* Connecting, selecting database */
$link = mysql_connect(192.168.0.112, root, )
or die(Could not connect);
print Connected successfully;
mysql_select_db(dgdrivers) or die(Could not select database);
/* Performing SQL query */
$getlength = select * from man_links;
$length = mysql_query($getlength);
$idl = count($length);
for ($id = 1 ;; $id++ ) {
if ($id $idl) {
break;
}
$query = SELECT type, manname, manlink FROM man_links WHERE recordno=$id;
$result = mysql_query($query) or die(Query failed);
extract(mysql_fetch_array($result));

[PHP-DB] Re: Having trouble understanding how to manage arrays
Hi Bill,
Looks like you're making it hard for yourself, by querying the database for each
record found. Here is some code which should make your life easier. Of course, I have
developed functions which would turn the following code into 10 or so lines, but this
should work for your situation.
Adam
?php
/* Connecting, selecting database */
$link = mysql_connect(192.168.0.112, root, )
or die(Could not connect);
print Connected successfully;
mysql_select_db(dgdrivers) or die(Could not select database);
/* Performing SQL query */
$query = SELECT type, manname, manlink FROM man_links;
$result = mysql_query($query) or die(Query failed);
?
table border=0 cellspacing=0 cellpadding=5
?php while ($row = mysql_fetch_array($result)){ ?
tr
td?= $row[type] ?/td
tda href=?= $row[manlink] ??= $row[manname] ?/a/td
/tr
?php } ?
/table
?php
/* Free resultset */
mysql_free_result($result);
/* Closing connection */
mysql_close($link);
?

Hi all. I am very new to this, and have been reading my way through php,
but have come accross a stumbling block that I just don't seem able to get
past, although I'm sure it's something simple.
I have a very basic mysql database set up, that contains a table with 4
fields- type, manname, manlink, and recordno
What I need to do is pull all records from the database, and provide a list
on a page with links to the url's stored in manlink with the lable manname.
So far, I've come up with the script at the end of this message. This
script works beautifully for me- for the first record.
The fact that it works 'beautifully' is just luck!
Could anyone point
out why it won't go on to any other records?
Your logic is completely messed up :)
?php
/* Connecting, selecting database */
$link = mysql_connect(192.168.0.112, root, )
or die(Could not connect);
print Connected successfully;
mysql_select_db(dgdrivers) or die(Could not select database);
The above is OK. But for better error reporting you should replace the die()
statements with something like:
die('Could not connect. The error was: ' . mysql_error())
This will display your message along with the actual error returned by mysql.
/* Performing SQL query */
$getlength = select * from man_links;
$length = mysql_query($getlength);
$idl = count($length);
for ($id = 1 ;; $id++ ) {
if ($id $idl) {
break;
}
$query = SELECT type, manname, manlink FROM man_links WHERE
recordno=$id; $result = mysql_query($query) or die(Query failed);
extract(mysql_fetch_array($result));
/* Printing results in HTML */
print table\n;
print pa href=$manlink$manname/a;
print /table\n;
}
/* Free resultset */
mysql_free_result($result);
/* Closing connection */
mysql_close($link);
Here's the standard way to retrieve a set of results from a query:
$query = SELECT manname, manlink FROM man_links;
$resultID = mysql_query($query)
OR die(Error in query $query : . mysql_error());
while ($row = mysql_fetch_array($resultID)) {
print Man Name : . $row['manname'];
print Man Link : . $row['manlink'] . 'br';
}
mysql_free_result($result); # optional, as php cleans up automatically
mysql_close($link); # at the end of the script

Re: [PHP-DB] problem with a small script
Suman, Firstly, it's a bit longer than necessary. Make your form a 'POST' rather than 'GET' and you'll hide your query and ?php echo $fname; ? will then be the equivalent. I presume that you have been able to display other PHP stuff? Check your php.ini file and make sure that the part that allows you to use the short ? rather than having to always use ?php is enabled.
