I have various PHP scripts that use the same database.
The startup script default.php sets the connection once for all the scripts.
This connection is set in $_SESSION to make it a global variable for all scripts.
When switching from page default to page faq, I get errors I can't explain. Any help is highly appreciated.
TIA, Cor

The first two lines give it away ;)
You're missing a session_start().

Thanks Chris,
I included session_start(); as first line in faq.php, but now I get other warnings /errors:
Warning: mysqli_query() [function.mysqli-query]: Couldn't fetch mysqli
in line "$result = mysqli_query($link, $sql);"
Warning: mysqli_error() [function.mysqli-error]: Couldn't fetch mysqli
in line "if (!$result) { echo "Can't execute query ($sql): " . mysqli_error($link); exit; }
Actually - shoot me for not noticing this before.
You can't store a resource or connection in the session.
You have to recreate your connection in each page.
See http://php.net/session .

Hi Chris,
I recreated a new connection in faq.php and it's working now.
I had the impression that 1 connection could last during a user session,
but apparently a user session may need many connections.
Thanks again, Cor
