Re: [PHP-DB] how many databases should I create
On Mon, 18 Oct 2004 14:53:41 -0500, Norland, Martin [EMAIL PROTECTED] wrote: That all really depends on you. I would certainly say that, in general, any given database should only have one users table (with a separate table holding roles, permissions, etc.) In all likelihood - if all of these systems will be working together within a single company, and be built in a common way - you'll likely find it easier to have them all in one system. The counter to that, of course, is that information like payroll certainly shouldn't be easily accessed - so that might be one case where you might want a separate database. You'll really just have to weigh the benefits of having the data together (generally convenience, though there are reasons along the lines of joins and such) with the costs of any lost security or lax in responsibility. shouldn't a good rdbms take care of that though (with reasonable security measures)? can't you get fine grained user privs, at least with a proper db? postgres?

But I have a second pull down menu whose items need to display based on the item chosen from the first pull down menu. I can do two lists seperately, but I need the second pull down menu to be a result of the first, and I can't figure a way to do it in PHP without reloading the page, which I don't really want to do. Is this a javascript-dependent function, in that a js will have to make the call to the database via some sort of scripted php/mysql request? I really like to avoid javascript if possible, but I'm unsure there's an alternative. You're describing what I think is called Dynamic Options. Doing a Google for javascript dynamic option or javascript dynamic select will pull-up a few examples. Most of these solutions will expect you to load all data into javascript arrays. In other words, you don't have to reload the page, because all of the data is already present. This approach doesn't work well when dealing with large amounts of data. If you're running into this, use javascript's window.opener feature. It allows you to spawn a second window that retrieves data and sends it to the first window. Cripes!

[PHP-DB] Re: [PEAR] Pear installation error
On 8 Oct 2004 17:03:15 -, Kevin Kraeer [EMAIL PROTECTED] wrote: I'm a one man band working for an ad agency...good times. At any rate, a client has requested that form values submitted through their website be written to an excel document. I investigated and decided PEAR was probably my best bet (there's an excel writer module if I understand correctly). So, I began what has become a quest to successfully install PEAR to our staging server. It's a Win2K Server running IIS and PHP 4.3.6. Whoever initially installed PHP 4 did not install PEAR along with it for some reason. So I decided to run the command line installer, with the following directories set up: Installation prefix - C:\PHP\pear Binaries Directory - $prefix\bin PHP code directory - $ prefix\docs Documentation base directory - $prefix\docs Data Base Directory - $prefix\data Tests Directory - $prefix\tests php.exe Path - C:\PHP\php.exe I then run the installer, and it does fine for a while. Then, after 'Extracting Installer' appears I get this: Warning: main(PEAR.php): failed to open stream: No such file or directory in C:\PHP\pear\Archive\Tar.php on line 21 Fatal error: main(): Failed opening required 'PEAR.php' (include_path='/C:\DOCUME~1\ADMIN~1.ORB\LOCALS~1\Temp\3\gop1c.tmp') in C:\PHP\pear\Archive\Tar.php on line 21 So it seems pretty clear that it's an include path problem to me. In my PHP.ini, go-pear added include_path=.;C:\php\pear So maybe I need to change that to someplace else? But I'm also not so sure about that forward slash in front of 'C:\DOCUME~`.' Any ideas or advice would be greatly appreciated. As I said, I'm on a solo mission over here - no IT guys, no programming dept. Just ME. heh. This is probably going to get me flamed terribly, or rather completely ignored... If it is just you, why on earth don't you upgrade to a real operating system? *nix + apache[1-2] + php is go beautifully together..., won't cost you anything in licencing (assuming you don't get a proprietary unix), and is much less likely to be troubled by viruses and whatnot... I say this because usually the installation of these three packages is done with about 5 clicks, and gets configured pretty much by itself (of course, if you want security and stuff, you have to change the config, but I am sure that is not different to IIS...). Just a suggestion. Cheers Antoine -- G System, The Evolving GUniverse - http://www.g-system.at -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] [Newbie] switch, if, or something to choose queries and echo formatting--PLEASE help
So I attempted to do this:
switch($_GET[page]){
$count=1;
$table = mysql_query(SELECT * FROM thumbs,$db);
echo(table border='0' cellspacing='1' cellpadding='1' width='300'
align='center'tr);
while ( $r = mysql_fetch_array($table) ) :
if ($count==4){
echo (/trtrtd span='4'img src='images/spacer.gif' height='10'
width='1'/td/trtr);
$count=1;
}else{
$id=$r[id];
$pic=$r[pic];
$thumb=$r[thumb];
$pname=$r[pname];
$pcom=$r[pcom];
echo(td align='left' valign='top' width='100'a href='$pic'
target='blank'img src='$thumb'
border='0' align='left'/abr
clear='all'b$pname/bbri$pcom/i/td);
$count++;
}
endwhile;
break;
Which did not work. I wondered if that was too much for the case or if
you couldn't nest. PHP.net says The switch statement executes line by line
(actually, statement by statement). In the beginning, no code is executed.
Only when a case statement is found with a value that matches the value of
the switch expression does PHP begin to execute the statements. PHP
continues to execute the statements until the end of the switch block, or
the first time it sees a break statement. Which made me think
otherwise--but, hey, something's wrong.
Yip, the logic of the switch statement. You simply don't have a case
statement. I must confess I don't understand fully what you are trying
to do yet but I don't think this is the way to go. The above extract
should be enough to see what I mean... Only when a case statement is
found with a value that matches the value of the switch expression
does PHP begin to execute the statements. You don't have one so... it
won't ever start!

[PHP-DB] mysql to postgres migration blues...
Hi,
I am trying to get skilled up on postgres and decided to port a little
movie database I wrote for mysql with php to access it.
I used an auto converter for the bulk and then tried to tweak. The
following code does not work but the error message it gives me is
strange. It tells me that the connection string used on line 82 (where
it calls pg_query in makelistboxentries) is invalid... but the same
string/connection works just great in another script... any pointers
appreciated.
Cheers
Antoine

The global keyword works a little bit differently in PHP. You need to
inform your function that your variable is global, as opposed to
declaring it as global outside the function. Like:
$link = database connection
function processData () {
global $link;
...
Like i said, I'll get there ;-). Cheers! I hope you folks don't mind
answering some rather basic questions... I am going to be starting
some serious development soon and promise to search the docs first
:-).
I have just followed up on the suggestion of pear and it looks like a
winner. That may mean a change of mailing list but all good for the
moment.
