Re: [PHP-DB] Searching many-to-many map tables
you must have three tables user (have at least user_id field) group (have at least groupd_id field) user_group (have 2 fields: user_id and group_id, you can also have user_group_id - depends on your need) /* if you only need the user id */ select user_id from user_group where group_id in (1,2); /* if you need other info */ select UG.user_id, U.*, G.* from user_group UG left join user U on UG.user_id = U.userid left join group G on UG.group_id = G.group_id where UG.group_id in (1,2); hth, ~ John On 2/7/07, Steve McGill [EMAIL PROTECTED] wrote: Hello, I am trying to find out how to search a many-to-many map table efficiently.

Until now, I can either do this with multiple queries and using PHP array_intersect, or one really ugly MySQL query: select user, count(user_group) as num_groups_found from users_groups where group IN (1,2) GROUP BY user HAVING num_groups_found=2 i.e. narrows down the groups I'm looking for and makes sure that they are all found for a user It works quite reliably I think but it's such a rubbish query that I was hoping that somebody could teach me some syntax that is better.

Re: [PHP-DB] retaining form information when someone presses back
try using:
header http://www.php.net/header(Cache-control: private);
i'm not sure that will work, try playing with header cache-control. anyway
as Bastien metioned it is better to have your form redisplayed with values
the user entered when validation failed rather than asking the user to click
the back button of their browser.
try this sample (not tested, too lazy :) but should work):
?php
$var1= NULL;
$var2= NULL;
if (isset($_POST)) {
$var1= $_POST['var1'];
$var2= $_POST['var2'];
}
echo 'form method=\'post\'';
echo input type='text' name='var1' value='$var1' /;
echo input type='text' name='var2' value='$var2' /;
echo 'input type=\'submit\'';
echo '/form';

I have a custom application in PHP in which a user fills out a form of
information. When the user submits, I perform sanity checking on the
user's submitted data and refuse to actually process/insert it if
those checks fail. However, my users are complaining that when they
press back to correct, all the data is gone from the form and they
have to re-enter it all. I know many websites that can retain the form
data when someone presses back; how is this done?

Re: [PHP-DB] Generating pages with full stories
Here's how you should do this (IMHO):
On you front page make a sql query say you want to display the latest 3
events. Your query probably will look like this:
select event_table_id, title from event_table order by date_created desc
limit 3;
then from the result make a while or for loop (for example your result is
stored in an array $aResult)
foreach ($aResult as $value) {
echo 'a
href=eventFullStories.php?eventId='.$value['event_table_id'].''.$value['title'].'/a;
}
Then on your eventFullSyories.php just query the event_table for that
eventId and display the event full story.

1. Where are the stories going to come from? If you plant to take news
stories from other sites and use them on your own site, there are
serious legal issues involved.
2. If you want to write the stories yourself, or invite visitors to
write your stories, then you probably want a simple content management
system using PHP and MySQL. There are a lot of them about. Google or ask
for recommendations.
3. If you'd prefer to make the site yourself in order to learn PHP +
MySQL programming, you can find lots of tutorials. Google PHP Tutorials
and look around.

Re: [PHP-DB] Distinct Partial Matches: RegExp
i'm a bit confused. if i'm getting you right heres my 2 cents:
first you do sql query using DISTINCT
when the result are returned to you, you can then run thru the result array
using preg_replace. heres an example:
$aVar= array(
'animal-dog-5',
'animal-dog-3',
'animal-cat-1',
'animal-cat-22',
'animal-bird-5',
);
$aResult= array();
foreach ($aVar as $value) {
$tmp= preg_replace('/-\d*$/', '', $value);
$aResult[$tmp]= $tmp;
// if you want to conserve a bit of resources asign NULL;
// $aResult[$tmp]= NULL;
}
