Re: [PHP-DB] help please... session - database
Try
$link = addslashed($HTTP_SESSION_VARS[HREF])
and then use $link in the sql insert
and..
stripslashes(query result)
when you retrieve the value and need to display it on the page.

hello,
i have hit a major stumbling block and am now getting really
frustrated.. if someone could point me in the right direction i would
really appreciate it..
- i have a set of forms across a number of pages
- the user enters data into each of the forms and these are placed in
a session variable
- at the completion of form entry the session variables are supposed
to be passed to a mysql database
- one of the variables is a URL for some reason the form entry the
data is encoded so that a full stop '.' is changed into an AT '@'
- I have tried urlencoding and decoding the session, using str_replace
for the @ .. adding slashes
- for some reason this just wont work ..
...
help?
...
i.e Adds form post to session
if (is_array($HTTP_POST_VARS)) {
while (list($var, $value) = each($HTTP_POST_VARS)) {
session_register($var);
$HTTP_SESSION_VARS[$var]=$value;
}
}
i.e adds session to database (simplified so as to find problem)
$title =stripslashes($HTTP_SESSION_VARS[title]);
$href= $HTTP_SESSION_VARS[HREF];
$fee =stripslashes($HTTP_SESSION_VARS[fee]);
$result= mysql_query(INSERT INTO links (Title, Hyperlink,fee) VALUES
('$title','$href','$fee')) or die(mysql_error());
print $result;

Re: [PHP-DB] Averaging Numbers
Maybe I am missing the complexity but I would just add them all up as
you retrieve them (or where you are printing them out) and then when you
finish the loop divide the total by the number of of number you are
averaging over have (i.e this would be 15 if you are taking 15 days).
something like:
$sum = 0;
for i=0 to i=15
{
$valueRetrieved = retrieve result of row i
$sum += $valueRetrieved
}
$average = $sum/15
hope this helps

I'm having a hard time learning how to get an average. I have a database
that gets a number and inserts in into a MySQL database every 1/2 hour
during the day. For the current half hour, I want to get the last 15 days
numbers for the same time as the time it is now. I can retrieve and display
the numbers fine, I just don't know how to go about putting these all into
variables or an array or if I can do this within a query and then take an
average for them. Hope that made sense. Thanks.

Re: [PHP-DB] upload problem ...
Steve, When you use input type=file the web server uploads the file to a temporary directory which it must have write access to, i.e. the user that the httpd process is run as must have write access to /php/tmp. To my knowledge there is no way of allowing the httpd process to write to that directory using your ftp users/password. Bear in mind that you could change the temporary upload directory from /php/tmp to /tmp. do you have full access to you box or only an account? hope this helps ciao Andre. Steve Brett wrote: hi, i have a site and need to write a script to upload / download files so the database can be updated / backed up. i've tried setting up an input type=file ... and this works fine on my machine but php gives an eror onthe server saying that the /php/tmp dir cannot be written to by, i assume, the nobody account within whihc the web server runs. i need to be bale to write to the httpd dir using php and then i can get the db to import the files. i have an ftp username and password but don't know how to get php to pass the authorisation the server. the site is already password protected just using a table of username / passowrds. many thanks in advance Steve -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP-DB] How do I backup my MySQL database? asks a Newbie.
Install phpMyAdmin and this will give you a web interface to manage your DB. You can do a dump of your database using it.

The site is run by my ISP so I don't have control of the server.

Re: [PHP-DB] raw file header in http
Try the following: create a link to a script download.php which will read the file (from anywhere on the disk) and send it to the user like this: header(Content-Type: application/force-download); header(Content-Length: .filesize($filename)); header(Content-Disposition: attachment; filename=.$orig_filename); readfile($filename); exit; This should give him a download dialog box and set the filename in the dialog box to $orig_filename. hope this helps ciao andre. schiarat@libero. wrote: I' ve a file in a directory(/tmp) out from http root of web server.
