[PHP] Re: Amount of data in the database
A pretty easy way of doing it is to add a size field to the table. Whenever you INSERT INTO or UPDATE the table, update this field to contain the size of the data for the current record. Then, whenever you need to check the amount of data for a particular user, just use this query: SELECT SUM(size) FROM sometable WHERE user=someuser Hope this helps /Lars Olsson ([EMAIL PROTECTED]) PS.

Re: [PHP] Re: Amount of data in the database
Hello again! Basically...you can't. What I meant was that when you insert the data into the table, you need to store the size as well. Consider the following table (called files): dataID user filename size filedata [int, autoincremented] [int] [varchar] [int] [blob] Now, let's say user 3 uploads the file 'airplane.jpg' to the server. We need to have the following information: $filename = The name of the file $filedata = The actual file $size = The size of the uploaded file You can find out about how to get these variables from http://www.php.net/manual/en/features.file-upload.php Then you insert the data into your table; INSERT INTO files(user, filename, size, filedata) VALUES (3, $filename, $size, $filedata) This means that every time some user upload a file, the size of the file will be tied to a particular record. Then you just use MySQLs built-in SUM function to find out the total amount of data (check my previous post) Kindly /Lars Olsson ([EMAIL PROTECTED]) Denis L. Menezes wrote: Thanks Lars.

[PHP] attachment problem
Hi all! I'm writing a webmail application in PHP and most basic things are working now. However, I've recently run into a problem concerning mail attachments. This is the situation right now: When the user opens a letter there are links to all attachments. The links looks like this: http://www.lassoweb.nu/webmail/attachment.php/mailbox=INBOXmsguid=218part=2 Mailbox is the mailbox name, msguid is the message number and part corresponds to the part of the letter that is an attachment. When the user clicks the link the attachment data is extracted from the message and displayed in the browser (if possible). This works nice, but here comes the problem. Since the document is named 'attachment.php', that's the name that comes up in the save box whenever the user tries to save the file. Iv'e tried setting the Content-Disposition header to tell the browser what to call the attachment, but to no avail. The browser still insists on calling all attachments 'attachment.php'! I've been trying to figure this out for a couple of days now, but no luck yet. Perhaps someone out there have had the same problem (and solved it)? I'm thankful for any hints /Lars 'lasso' Olsson ([EMAIL PROTECTED]) PS. One solution might be to 'trick' the browser by creating a fake URL (like http://www.lassoweb.nu/webmail/void/bob.gif), but in order for this to work I need to tell Apache to send all requests to the 'void' directory to a single PHP file. Anyone knows how to set this up? DS. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] attachment problem
Yes, I've tried using the Content-Disposition header. It doesn't seem to
work...here are the relevant parts of my code:
snip
// Change Content-Type so that it matches the MIME-type of the part
header('Content-Type: ' . $type . '/' . $subtype);
// Check if there is a name for the part
if (isset($name)) {
header('Content-Disposition: inline; filename=' . $name);
}
else {
header('Content-Disposition: inline');
}
/snip
I've tried printing $type, $subtype and $name and they all contain
correct values...still no luck.
As per your suggestion I tried using wget -S to check the headers. Here
are the results:

Hi!
I don't think that should be considered a problem for PHP output
buffering. Du you know ANY user that would that would wait for a 1.5MB
page to display? And if you're transferring large binary files to the
browser (a LARGE bitmap for example) you could get around this problem
by doing
1. Open the file
2. Read a reasonable amount of data (say, 10 bytes)
3. use ob_flush to sende the data to the browser
4. Repeat step 2 and 3 until all of file is read
5. Use ob_end_flush to send the rest of the buffer
6. Close the file
Hope this helps

You get this error message whenever $_GET doesn't contain anything.

If so,should i always just do this
$_POST['op'] = '';

Or would it be better and more space efficient to do this
$op = isset($_GET['op']);

}
Cause if i do that the Notice Message dissapears for some reason i yet fail
to grab.
This doesn't work since the result of isset($_GET['op']) is either true

if (isset($_GET['op']) {
$op = $_GET['op'];

[PHP] calculating psysical path (a first try)
Hi list!
Something I use quite often when programming in ASP is the
Server.MapPath method. This method expects a virtual path (on the web
server) and returns the corresponding psysical path. I haven't seen this
anywhere in PHP, so I've hacked my own little routine to do this (see
below). But I still have two questions:
a) Is there perhaps a built-in function I can use instead? I browsed
through the manual quite a lot, but I haven't found quite like this.
b) If there isn't a built-in function, perhaps you could help me make my
function better? It seems I use a lot of code for this TINY problem...
Here's the function:
snip
// This function calculates the physical path for a given virtual path.
function map_path($virtual_path) {
// Deklarera necessary variables as global
global $HTTP_SERVER_VARS;
// Find out where this file is located in the psysical file system
$script_filename = $HTTP_SERVER_VARS[SCRIPT_FILENAME];
// Find out where this file is located in the virtual file system
$script_name = $HTTP_SERVER_VARS[SCRIPT_NAME];
// Calculate which folder in the psysical filesystem that corresponds
// to the root folder in the virtual filesystem
$psychical_root = substr($script_filename, 0, strlen($script_filename)
- strlen($script_name));
// Calculate which folder in the psysical filesystem that corresponds
// to the given folder in the virtual filesystem
$psychical_path = $psychical_root . $virtual_path;
return $psychical_path;

I changed the session_save path in my .htaccess file to: /home/httpd/vhosts/mydomainname/httpdocs/sessions/ and created some sessions. The creation and destruction of sessions works fine as long as the user logs out correctly, but PHP fails to garbage collect sessions when the user just quits the browser. I've tried changing the session.gc_probability to 100 (and waited until session.gc_maxlifetime had passed), but it still doesn't work. Now I'm stuck with a bunch of deserted session files that don't seem to go away. Any ideas on how to solve this? /Lasso ([EMAIL PROTECTED]) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Dynamic Web Pages
Hi! Database queries and global variables are not related to each other. It usually just boils down to the following steps 1. Collect data that that's needed for the database query (via $_GET or $_POST) 2. Run the query against the database and store the results in some nice variables (arrays/strings depending on data) 3. Display the results within the page by printing the variables at appropiate places inside your template file (test.php). Obviously the possibilities are endless, but if you want a starting point you could try the following link: http://www.php.net/manual/en/ref.mysql.php (check under Examples) Kindly /lasso ([EMAIL PROTECTED]) Rolando Morales wrote: I would like to have the same page (test.php) have different text in it depending on a database entry. which is easy enough. but I want it to be on the fly. example list would be created on the fly depending on databse entries. which ever entry was picked (lets say STLT) it would open up my template test.php and it would but the STLT info on the page.

[PHP] Re: Is it possible...
No. Since PHP is executed on the server, the only thing that is sent to the browser is pure HTML (and client-sided scripts like JavaScript). This means you cannot just get the source code of a PHP page by just browsing it. /lasso ([EMAIL PROTECTED]) Apollo wrote: Is it possible download php scripts from webpages ? for example i need php.net scripts or others :-) If yes, how ? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Preventing Multiple Log-Ins after Authentication
I agree. Using a database is usually a good way of storing session information. But as noted by Dennis below, automatic logout may require additional scripts running in the background. This is a bit inferior in PHP compared to ASP. In ASP, support for automatic session destruction is implemented by having a magic function (called Session_End) which will be called automagically by the web server whenever a session expires. Having this in PHP would be very nice too! /lasso ([EMAIL PROTECTED]) Dennis Moore wrote: If you do not want to use cookes and use SID or trans SID; Another method is to track your logins via a database. This can be resource intensive though.You need to update the database upon each click or have an empty window refresh every 1-5 minutes. If there is no activity for 15 or 30 minutes automatically log the person off in the database. This requires a process to run in cron or a separate background program. The advantage of this is that is very easy to add time based accounting to the session management system. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: ' giving problem while inserting in table.
Since ' is a string delimiter in MySQL it has to be escaped. Try using
mysql_escape_string($string)
(http://se.php.net/manual/en/function.mysql-escape-string.php) on all
the strings before you try to insert them into MySQL.

Hi,
I am making a faq maintenance system using mysql and php.
To insert a entry in to a faq table i am using the following query:

now the problem is when $frm[question] has some string like: why i can't
eat.
i get the following error:
MySQL Error: You have an error in your SQL syntax near 't eat?' ,answer =
'Please recheck the power of your specs:)' ' at line 3.Putting a '\' before
' (e.g. \')solves my problem...but when i open the same quesion to edit it,
again i have to put backslashes where ever i find ' in the quesion or

Can anyone please suggest a solution to this.
thanx and regards

[PHP] session_start and HTTP headers in Mozilla, plz help
Hi!
I've run across a problem when using session_start and HTTP headers in
Mozilla. I'm trying to write a snippet of code that checks whether a
user has logged in or not. If the user has a session variable set I want
to display the page and if he or she hasn't I want to give them a 403
Forbidden header. My current code looks like this:
[top of page]
?php
// Start session handling
session_start();
// Check login
if (isset($HTTP_SESSION_VARS[xyz])
and $HTTP_SESSION_VARS[xyz] == yes) {
?
html
[page contents]
/html
?php
}
else {
header(HTTP/1.0 403 Forbidden);
}
?
[end of page]
This works perfectly in IE 6 (I get a 403 Error Message) but in Mozilla
I just get an empty page (containing just the html and head tags).
Most other headers seem to work though.
If I use header(Location: somepage.php) both Mozilla and IE correctly
redirects the browser. I don't know if it's a bug in IE or Mozilla or if
I'm plain stupid, but perhaps someone else has experienced this and
are willing to give me a hint?
Thanks
