And if you have difficulty, post your problems to the PHP-INSTALL list.
Since this is the database list, you *should not* post those questions here.

[PHP-DB] forced page links...
I am wondering if there is a good tutorial on how to use php to make users come from a page before they can access another. For instance, say you have one page called index.php which contains a form that once filled in links to a confirmation page to verify the users data was entered correctly then from there links to a page that stores the users data into a database table. The problem I would like to alleviate is to make sure the users cannot just type in the name of the last page in the url and put a blank entry into the database. I have read a few tutorials on using sessions but I am unclear on how the use of sessions would require the user to visit each page in succession.

[PHP-DB] Re: forced page links...
Hi there :) I use session variables to do this, once the user has logged in
and you know they are who they say they are, set a session variable using
session_register(isloggedin);
$isloggedin = yes;
And at the top of every page you want protected simply do a check to see if
it is set or not. Below code checks to see if that var is set and if not it
redirects them to another page.
?php session_start(); ?
?php
if (!isset($HTTP_SESSION_VARS[islogged])){

Re: [PHP-DB] Re: forced page links...
Hello!!
What I would do is have both the 2 page and the last page on the the
same page!!
All my pages are only two...a form page and a processing page...that's
it
However
You could also have a variable pass from page to page, like a hidden
variable, either in a form, or with cookies.
And check for that variable every page with an If...else..statement.
like
If (empty($CheckPLEASE){
echo Sorry You are out of order;
exit();
}else{
echo hey your good to go!!;
}
And so on and so on...

Re: [PHP-DB] Re: forced page links...
hi jas,
am sure you asked this before and i already replied. Anyway miles posted
this which is more elaborated than the one i proposed:
***
This is at the top of every file requiring an authenticated user on one of
our sites:
? include(secure.php)?
and secure.php consists of this, all on one line, with no cr or lf at the
end.
? session_start();session_register( origin );$origin=$PHP_SELF;
$HTTP_SERVER_VARS[ PHP_AUTH_USER ] !=winkum
TP_SERVER_VARS[
PHP_AUTH_PW ] !=blinkum ) { if( !session_is_registered( member_id ) )
{ header(Location: user_logon.php\n); } }?
The user_logon.php script handles all details of processing the user:
reading their cookie and authenticating, prompting for username/password,
authenticating setting cookie. If authentication succeeds member_id is
registered and created as a session var (it contains no info, merely
exists) and the user is returned to the originating page, or by default, to
index.php.
The $HTTP_SERVER_VARS with the hard-coded passwords are there so that htdig
can be authenticated to index these pages.

[PHP-DB] Sorting the result
Hi,
I've come across a problem and I'm affraid that I'm lacking the skills of
writing proper SQL queries in order to solve this. I'm building a little
search engine for my site (yes, from scratch! It doesn't have to be the
best, but I think that for my personal use it will be enough) and the bit
of code I have right now is as follows:
snip
/* I'm using MySQL 3.23.37 together with 4.0.6 on a FreeBSD box */
$article_query = mysql_query(select article_name, article_text from articles where
article_name LIKE '%$q%') or die (mysql_error());
/* where $q is the search query with a space added in front */
while ($results = mysql_fetch_array($article_query)) {
$art_name = $results[article_name];
$article_text = $results[article_text];
$q_count = substr_count($article_text, $q);
echo b$art_name/bp$article_textp;
}
/snap
But what I'd like to achieve is that the results would be displayed in a
way ORDER BY $q_count DESC - the entry with most $q_count would be
displayed first, next one second etc. I'm sure that there is a way to sort
the array with PHP, but is it also possible to let the MySQL do the job?
It would save some CPU power I think... if not, what would be the easiest
way to do it with PHP?
TIA,
Kristjan
P.S. Please CC me as well, I am only on the digest.

Put the ORDER BY $q_count DESC in your SQL statement and that will make
MySQL do the sorting for you. PHP will get it already sorted.
Is that what you wanted?

[PHP-DB] pg_pconnect Causing SegFaults?!?!
Greetings everyone, I've been having a very frustrating problem over the past few months that I've ***finally*** tracked down the cause of Any questions/comments/thoughts/ideas you can provide would be *greatly* appreciated. Symptoms: - IE, Opera, Lynx all report page cannot be displayed and/or server error about half the time - NS has no problems at all. - Apache error.log shows child (PID) seg faulted. Problem post analysis: - The Apache processes can accept and successfully serve one connection from a client. The next connection results in the Apache child process seg faulting, the error getting logged in error.log, nothing gets reported in access.log, and the Apache parent process respawns a new child. - The newly spawned child will accept and serve one connection from a client before also segfaulting. I've eliminated every possibility I could think of while troubleshooting this. i.e. it's not SSL, it's not PHP itself, it's not Apache itself. It's the pg_pconnect() function. Throughout my troubleshooting, I came upon it by accident, really, that I discovered all my problems went away when I replaced the pg_pconnect() function with the (almost deprecated according to the docs) pg_connect() function. In troubleshooting this, I created a shell script that continuously loads various pages from the site (using Lynx -dump -mime_header url), counts the iterations, and bails as soon as a page fails to load. Running this against plain HTML files, PHP scripts (i.e. that simply echo something or provide phpinfo(), etc.), over SSL or not all work just fine. (15,000 loads in each case without fault.) As soon as I try accessing a PHP script that includes the pg_pconnect() function, it dies almost immediately. If I stop/start Apache right before trying this, I'll get X successful loads (where X = Apache's 'StartServers' property). After that, I'll get a continuous mixture of successful and failed loads from then on So, let me repeat here As soon as I switched from pg_pconnect() to pg_connect(), everything worked perfectly after that. (i.e. 15000 loads without an error.) More info: - My platform is up-to-date Debian GNU/Linux (sid) (Apache 1.3.23, PHP 4.1.1, PostgreSQL 7.1.3, etc.) - As above, this is *not* browser specific. (Found a *lot* of google hits with people having problems with IE and SSL and seg faults, etc. Completely unrelated.) - Note from above, though, that NS is unaffected by this problem. It *never* has a problem. My assumption is that NS will simply silently retry (several times) if the connection fails for some reason, until it does get a valid response from the server (Kudos!!! ;-) So, any thoughts? Comments? Suggestions? Have I found a bug in pg_pconnect()? How can I provide more info to track this down further?

RE: [PHP-DB] why won't session_start() work?
Ryan,
you need to make all of those calls *before* ANY output has been sent by
your script, otherwise you can't send a header any more. so the TOP of a
script might look like
?php
session_start();
$signor = $monsieur + $madame;
session_register(signor);
// the rest of your code goes here
?
html
?php
// more PHP
?
if you get what I mean. you can actually do a lot of coding before you start
the session if you want, provided you haven't done any echo() print() or
anything that sends information as output.

[PHP-DB] Question about advanced SQL
Hi. I need some guidance for writing an effective query (instead of processing through PHP). I lets says I have two tables, tblCDs and tblOrders. tblCD cdID| cdTitle | cdArtist -- 1 | Great Hits | Bon Jovi 2 | Forever Young| The Youngsters 3 | Now and Then | Beach Boys 4 | Cheesy Name | Two Tones tblOrders orderID | cdID_FK | ordererID -- 1 | 1| 442 2 | 3| 233 3 | 1| 233 Now, I want to select all the records from tblCD where the cdID does not appear in any row of tblOrders.cdID_FK This means that it selects all the CDs that have not been ordered. The results of the query should be cdID| cdTitle | cdArtist -- 2 | Forever Young| The Youngsters 4 | Cheesy Name | Two Tones I know how I can do this in PHP (two queries - put all cdID_FK in an array, and on displaying the other query, check if it is in the array, and display if not) but there HAS to be an easier way.

RE: [PHP-DB] Question about advanced SQL
SELECT tblCD.cdID, tblCD.cdTitle, tblCD.cdArtist FROM tblCD, tblOrders WHERE tblOrders.cdID = tblCD.cdID AND tblCD.cdID NOT IN ( SELECT cdID FROM tblOrders ) The support for this sort of nested query will very between RDBMSs but the statement above is most generic. Databases like postgres will not only support this but they will also have proprietary ways of achiveing the same thing more efficiently. Some databases also support LEFT JOIN, OUTER JOIN directives but support and implementation will vary. I havn't tested the above query but it should work :-) Although it probably isn't the most efficient.

[PHP-DB] Storing image path to database
Hi,
Woud someone be able to help?
I can't for the life of me figure out how to get this to store a image path
instead of the image itself. In other words I want to make this so that the
user isn't uploading an image. I want to use a radio or check box that they
pick from.
Any help would be appreciated.
?php
if ($submit) {
$data = addslashes(fread(fopen($form_data, r), filesize($form_data)));
$uid={$session[uid]};
$result=MYSQL_QUERY(INSERT INTO binary_data
(uid,description,bin_data,filename,filesize,filetype) .
VALUES
('$uid','$form_description','$data','$form_data_name','$form_data_size','$fo
rm_data_type'));
$id= mysql_insert_id();
print pbYour pet has been entered/b;
MYSQL_CLOSE();
} else {
?
form method=post action=?php echo $PHP_SELF; ?
enctype=multipart/form-data
File Description:br
input type=text name=form_description size=40
INPUT TYPE=hidden name=MAX_FILE_SIZE value=100
brFile to upload/store in database:br
input type=file name=form_data size=40
I already have the image on the server how do I change this to
store the path
pinput type=submit name=submit value=submit
/form
a href=store.phpback/a
?php
}
?
this is the table
CREATE TABLE binary_data (
id int(4) NOT NULL auto_increment,
uid int(10) NOT NULL default '0',
description varchar(50) default NULL,
bin_data longblob,
filename varchar(50) default NULL,
filesize varchar(50) default NULL,
filetype varchar(50) default NULL,
PRIMARY KEY (id)
) TYPE=MyISAM;
Thanks in advance

Re: [PHP-DB] Question about advanced SQL
Hi, I assumed that you was used MySQL for database. With MySQL you can used this SQL to find different row select tblcd.* from tblcd left join tblorder on tblcd.cdid=tblorder.cdid where tblorder.cdid is null sommai At 12:37 28/2/2002 +1000, Adam Royle wrote: Hi.

[PHP-DB] Object Base Database Access
Hi folks, i'm currently developing an module which provides an object based access to databases content (does not mean that i use OOP) for example we have defined an class descriptor for person, which specifies, that an person-record consists of the fields ID (which is the OID, fetched from sequence person_seq), mtime (which is also the mtime field and so touched when updating the record), firstname, lastname, ... then we can fetch the whole person record i.e. with: $person = obj_find ( person, array ( ID = 12 ) ); $person now contains an array with the person record in the form array ( OID = 12, mtime = 2002-02-28 07:23:00, firstname = douglas, lastname = adams ) you can also update whole objects (or some single fields) of the record or query multiple ones ... well, i'm not really good in explaining the stuff, so please ask me if you've got some questions. ~-n -- Enrico Weigelt== meTUX IT services software development, IT service, internet security solutions www: http://www.metux.de/phone: +49 36207 519931 email: [EMAIL PROTECTED]cellphone: +49 174 7066481 -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Force Refresh on Another Window w/ Javascript
I have a question, let's say i have my main page (so called) called
indexphp
I have also displayed a buttonin indexphp, which i will used the
onClick event to trigger a windowopen function to the same main
page, indexphp (but with parameters)
input type=button value=Add New Records
onClick=parentlocationhref='% echo $PHP_SELF; %?action=addnew';
so my indexphp should have these codes
%
if( $action == addnew )
{
}
else {
}
%
NOTE: i'm using asp tags set in phpini
during the adding of new records, i have also display another button
called Close Window And when I close this, how do i force the main
page (which is in a different window to refresh, to display the newly
added records) This is because after I have closed the add new records
window, and close it, i would have to have either a refresh button or
you would have to refresh it yourself
And thanks in advance

Re: [PHP-DB] Force Refresh on Another Window w/ Javascript
Sorry about the priority, guess it was set unintentionally, out of habit from my
working place, I think.

please don't use the important (X-Priority header) on your message - we're
all important here :)
anyway, your question - it's actually JavaScript that you want, and you need
something like this on the body of the HTML page in the window you open
body onClose=javascript:opener.document.refresh();
something like that will do it for you, take a look at the javascript
developer's guide (from developer.netscape.com)

[PHP-DB] Question about setting up multiple relations
Hi, I have an Image table in a MySQL database that will be used to store the location of all images used on my site Some images will relate to an Article table (articleid) and some images may relate to a Member table (memberid) As it's possible that there may be an articleid that is the same as a memberid, I am considering adding two fields to the Image table (article_id and member_id) one of which will be left blank for each record, depending on the image's relation For example, if mypicjpg is related to articleid 288 in the Article table, then I would insert 288 into the article_id field in the Image table but leave the member_id field blank Is this kosher, or is there a better way to do this?
