best bet is to put some error checking in.
function _check_db($query = '', $line = '')
{
if ( mysql_errno() )
{
echo "Error: Problem with DataBase : {$GLOBALS['db_database']}<br>\n";
echo "Error: " . mysql_errno() . ':' . mysql_error() . "<br>\n";
echo "Query: $query<br>\n";
echo "Line : $line<br>\n";
exit();
}
}
after every mysql command put this.
check_db($query, __LINE__);
ie.
<?php
mysql_connect($db_hostname, $db_username, $db_password);
check_db("connect: $db_hostname, $db_username, $db_password", __LINE__);
...
mysql_db_query($db_database, $query);
check_db($query, __LINE__);
?>
this will help alot in finding any mysql errors.
what was the command on line 27 ? email/news groups format posts, therefore
line 27 for you may be line 33 when Im looking at it.
