[PHP-DB] To many connections error
Hello everybody, I am running a community portal with LAMP . So far everything was running fine. This night the site went down for a few hours. The error message from mysql was to many connections. Is there a way to increase the number of allowed connections, or do I have a hardware problem here (celleron 1GHZ 256 MB ram)? The traffic for the site is rising constantly and I fear to get in trouble. Thanx for your help.

Re: [PHP-DB] PEAR::DB question
Jake Dunno if this will help, whether you're using MySQL or whether it works in PEAR. Look up mysql_data_seek() in the php manual. Cheers Terry --Original Message- Hello- I'm using the fetch method to get a result set. ie- $sql = select id,name from sr_names order by name; $result = $db-query($sql); while ( $row = $result-fetchRow(DB_FETCHMODE_ASSOC) ) echo $row['id'] . ' ' . $row['name'] . br; This works great! Now, I want to _re-use_ this result set without having to re-query the database. Then cycle through the result set. ie - $result-someFunction(); while ( $row = $result-fetchRow(DB_FETCHMODE_ASSOC) ) echo $row['id'] . ' ' . $row['name'] . br; So, the output here would be two of whatever was output. Does that make sense? Right now I'm having to do this: $sql = select id,name from sr_names order by name; $result = $db-query($sql); while ( $row = $result-fetchRow(DB_FETCHMODE_ASSOC) ) echo $row['id'] . ' ' . $row['name'] . br; $result = $db-query($sql); while ( $row = $result-fetchRow(DB_FETCHMODE_ASSOC) ) echo $row['id'] . ' ' . $row['name'] . br; If I already have the result set, can't I just tell it hey, put the cursor back at the top. I know I can fetchRow from a specific row in the result set, but then I'd have to get every row that way, which doesn't make efficiency sense, either.

Re: [PHP-DB] Bar codes in PHP
You need the bar code scanner on the client side. PHP has nothing to deal with the bar code. I have implemented the bar code system for the online library management system for one reputed school at Chicago. For every book, system is generating the unique id and later on i am exporting these ids and printing in the bar code format. You can find that software by simple google search. Later on librarians are using the bar code scanner, which will pick up the unique id and look up in the database for further processing. I hope this is clear. Let me know if you have any doubt. Regards, Hardik --- CPT John W. Holmes [EMAIL PROTECTED] wrote: PHP wouldn't have anything to do with it.

[PHP-DB] Session help...
Sorry for the slightly off-topic post... I have a couple pages that
use a login page. If the user tries to bring up one of these pages without
being logged in, then the pages redirects him to the login page. After
successful login, the user is directed back to the page they were attempting
to originally load. For some reason, this is not working and I have been
looking at this off and on for two days now without much luck. The first
section of code is the snippet that directs users to the login page, and the
second snippet is the code from the login page that sends users back.
First code snippet...
session_start();
if ($sbcuid $passwd) {
mysql_select_db($database, $Prod);
$query = select * from contacts_sa
. where sbcuid='$sbcuid' and passwd='$passwd';
$result = mysql_query($query, $Prod) or die(mysql_error());
# $data = mysql_fetch_assoc($result);
$test = mysql_num_rows($result);
if (mysql_num_rows($result) 0 )
{
$valid_user = $sbcuid;
$_SESSION['valid_user'] = $sbcuid;
}
}
if (!session_is_registered(valid_user)) {
$return_url = $_SERVER['PHP_SELF'];
$_SESSION['return_url'] = $return_url;
header('Location: http://ldsa.sbcld.sbc.com/DW/sa_login.php');
exit();
} else {
$sbcuid = $valid_user;
}
End of first snippet...
Second code snippet...
session_start();
if ($sbcuid $passwd) {
if (isset($_SESSION['return_url'])) {
$link = $_SESSION['return_url'];
} else {
$link = 'oncall_log.php';
}
mysql_select_db($database, $Prod);
$query = select * from contacts_sa
. where sbcuid='$sbcuid' and passwd='$passwd';
$result = mysql_query($query, $Prod) or die(mysql_error());
# $data = mysql_fetch_assoc($result);
$test = mysql_num_rows($result);
if (mysql_num_rows($result) 0 ) {
$valid_user = $sbcuid;

[PHP-DB] alphabetical sorting... limiting and paginating on next set of letter group
Hi Guys, Rather long topic I know. Sorry if it annoyed anyone. Hopefully someone can help here with the logic on this. I have a query where I am getting one column (designers) in a Table, ordered alphabetically. Right now.. this query is displaying EVERY distinct result (45 in total). This result is used for a subcategory menu on a page. I need to shorten this up considerably. What I would like to do is: Pattern Designers: A/B/C Artists Collection The Barrick Samplers Bent Creek Bobbie G. Designs Calico Crossroads Charland Designs Country Cross Stitch Click for D/E/F Click for G/H/I Click for J/K/L When the user clicks on one of the another Letter Groupings... the A/B/C changes to whatever they selected as does the displayed results for their selection. Is this even possible? Thanks! Aaron

Hey,
Thanks.
Is there anyway this can be performed one function/loop?
yes of course. =) just create a function that takes in two letters as a parameter,
then build the query string from it.
function($char_begin, $char_end)
{
$q_begin = strtolower($char_begin);
$q_end = chr(ord(strtolower($char_begin))+1);
$query = SELECT designer_name FROM designer WHERE designer_name BETWEEN
'.$q_begin.' AND '.$q_end.' ORDER BY designer_name;
//do your query here.
}
I knew it was possible with several queries.. I guess I was just looking
for a all_in_one solution.
Thanks for your help!
