Jonathan asks:
Whats your query look like? Do you perform any joins?
$query = SELECT * FROM $table WHERE CustNo='$CustNo';
Pretty vanilla stuff.
[ . . . ]
BUT! If the field is NULL, php spits out this:
Warning: Undefined index: Website in
f:\website\pmaco\admin\contacts1.php on line 241
The offending line was:
if ($row[Website]) {
// do stuff
}
and is now:
if (!is_null($row[Website])) {
if (strlen($row[Website])) {
// do stuff
}
}
Same warning msg. But if I substitute a numberic index, as in:
if ($row[33]) {
// do stuff
}
it works fine. But I need to use the associative index.

[PHP-DB] Design conundrum...
I'm trying to figure out the most elegant way to solve my database design problem and I thought I pick some at the brains on this list. The problem involves 2 tables, one of editors and one of categories, both have unique ID numbers. Each editor can have authority over an arbitrary number of categories, and conversely, each category can have an arbitrary number of editors. So what is the best way to represent this in the DB? (Which is PostgreSQL 7 BTW) Right now I am considering using an array in one of the tables but I have heard that walking the array to check values is both slow and somewhat cumbersome. Is there a good way to do this with a third table maybe? Please don't hesitate to point out my stupidity if the simplicity of the solution indicates it. :) Thanks, -Jesse -- 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]

With reference to my previous problem in connecting to the oracle database, I found out some additional information. I defined the TNS_ADMIN variable in the startup file and added this line to my php-script: putenv(TNS_ADMIN=/ora1/app/oracle/product/8.1.6/network/admin); and when I tried to echo this variable echo($TNS_ADMIN); The value is not being printed, it is not defined.When I tried the same thing at the command prompt the value was defined.What is the reason that the value of TNS_ADMIN is not being available to the php-script. -- 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]

If you want to select all categories that belong to a certain author, you would do this: SELECT c.* FROM editors_categories ec LEFT JOIN categories c ON c.id = ed.category WHERE ed.editor = ' . $editor_id . ' This selects all category records and joins them with the editors_categories table, then filtering the resulting recordset by the editor id stored in the editors_categories table.

Does there need to be something compiled into the php module? Everything
else seems to work with sessions, so I don't know why session_end()
wouldn't work.
its PHP Version 4.0.3pl1 on a cobalt raq4 server.

2 if (isset($HTTP_POST_VARS[ends])){
3 session_end();

#2 about the session documentation...
it sure is hard to find examples or explanations about garbage collection.
I found a post about session_set_save_handler on php.net for php and
postgresql, but still don't quite get it. Maybe give me a little time...
Aren't there php/postgreSQL lists? Anyone know of any? I was on the

am! If someone could help with sessions and Postgresql... Thanks
