Intermittent "No Database Selected" in PHP/MySQL?
- by ANE
Have a PHP/MySQL form with a dropdown box containing a list of 350 names. When any random name is selected, sometimes it works & displays info about that name from the database, and sometimes the form gives the error "No Database Selected".
Here's what I've tried, pretty much grasping at straws as I'm not a programmer:
Increasing max_connections in /etc/my.cnf from 200 to 2000 (even though only 4-5 connections are made and it's a lightly used server)
Changing mysql_pconnect to mysql_connect
Adding the word true to this connection string:
$mysql = mysql_pconnect($hostname_mysql, $username_mysql, $password_mysql, true) or trigger_error(mysql_error(),E_USER_ERROR);
Changing the word require_once to require on this line:
[?php require('/home/user/Connections/mysql.php'); ?]
Enabling MySQL & PHP query & error logging. (no errors logged)
Here is the code: [removed old bad code]
