Dreamweaver 8 bindings - to MySQL, error code 500

Question

Hello!
Well, I've spent five days searching online forums, and a few
posts come close to my problem, but not getting any clues to a
solution. I hope one of the resident experts or members could shed
some light...
Windows XP
Dreamweaver 8.0.2 (just upgraded - same problem)
- Used setup-v1.17-apache-2.2.2-win32.exe for setup - from
devside.net PHP 5.2.0-dev MySQL 4.1.7 (installed new after package.
Have two instances of mysql on my system - one active, one in
manual-inactive)
- All was going well until trying to establish bindings in
Dreamweaver. PHP is up and running. MySQL loaded, and database
connection fine. Bindings gets the error... "HTTP Error Code 500
Internal Server Error"
Just getting back to it... Again, thank you for your help!
Dreamweaver 8 has support for PHP 5. Version I'm using is
5.2.0. MX specifies versions 4.x and above are required. I'll have
to research if the support cuts off at 5.0.
My Connections file: conn_newland.php (I'm following the book
tutorial):
<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_conn_newland = "localhost";
$database_conn_newland = "newland_tours";
$username_conn_newland = "root";
$password_conn_newland = "";
$conn_newland = mysql_pconnect($hostname_conn_newland,
$username_conn_newland, $password_conn_newland) or
die(mysql_error());
$Recordset1 = mysql_query("SHOW variables", $Connection1);
echo "<table border=1 width=100%>";
while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)) {
echo
"<tr><td>".$row_Recordset1['Variable_name']."</td><td>".$row_Recordset1['Value']."</td></ tr>";
echo "</table>";
?>
Recordset parameters I entered in bindings:
Name: rs_journal
Connection: conn_newland
Table: tbl_journal
Columns: Selected - journalID, journal_entry
Filter: none
Sort: journalID Descending
Clicking Test gives: "HTTP Error Code 500 Internal Server
Error"
By the way, the reason I didn't specify a password in "root'
is that I had a problem before that I didn't know enough to
overcome, so had to reinstall MySQL. However, the same error occurs
if I specify another user name and password (previously set up).

Adding to this post...
I found the following at
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_16515.
However, it appears it may be referring only to Dreamweaver MX 2004
on Mac OS X. I have Dreamweaver 8 on Windows XP:
Verify that the connection scripts are up on the server
This section is related to the section above. In a web
browser, browse to the URL prefix you have defined in the Testing
Server category of the site definition and add
/_mmServerScripts/MMHTTPDB.php. For example:
http:/myserver/mysite/_mmServerScripts/MMHTTPDB.php. If things are
working correctly, you should see something like the following text
returned in the web browser:
Notice: Undefined index: Type in
c:\inetpub\wwwroot\mysite\_mmServerScripts\MMHTTPDB.php on line 13
Notice: Undefined variable: oConn in
c:\inetpub\wwwroot\mysite\_mmServerScripts\MMHTTPDB.php on line 20
When I go to the file above, this is the message I receive
(only thing that appears):
The files from the _mmServerScripts folder are for the server
model PHP-MySQL. You try to connect to a database using a different
server model . Please remove this folder outside the Dreamweaver
environment on both local and testing machines and try again.\n
Is there a hint here of what the problem is? I need some help
in possible interpretations.
Previous attempts made to solve:
- re-installed MySQL with mysql-5.0.24-win32.zip in
recommended directory (outside the www directory). I now have two
instances of MySQL on my local server - one set to automatic
loading and the other manual (switched off)
- one post suggested problem might be with ODBC - installed
SQL ODBC with mysql-connector-odbc-3.51.12-win32.msi. However, I
don't have a clue as to whether it's connected to anything...
- successfully connected to SQL database through root without
password and specific logon and password. No difference.
- other posts suggest problem could reside in php.ini,
htaccess, my.ini (SQL). I know where to find them, but don't have
an understanding of what parameters to shift, if any. One post
suggested a port problem, and I did see a port problem, presently
set to 3306.
From what I've been able to gather, this has been recognized
as an issue before, but there doesn't seem to be any documentation
online (or at least what I've been able to find) dealing with this.
And any mention of the problem that I've seen references
Dreamweaver MX, not 8, although I don't think the version
difference is a significant issue.
This error must be relatively rare, or I'd see more out there
about it. Still, I hope that at least one of the community experts
may have come across it.
Will be waiting with bated breath -- at least for a few
days...
Thanks!

Answer 1

Hello,
I have also had the same error - namely that whilst I could connect via ftp, upload/download files, and view database tables, any attempt to view of modify recordsets resulted in error 500.
Having checked other potential causes (e.g. selection/non-selection use of passive FTP setting, enabling of php, etc.), on the back of posts here I contacted my host and asked if if could relate to mod security, as further investigation revealed that the issue only occurred on sites where mod security had not been disabled (I don't like to disable mod security for obvious reasons - and I'm told you can't do that site by site with apache2 anyway).
After a few false starts, the problem was resolved - with the following response from my host: "The false positives were being generated by "/_mmServerScripts/MMHTTPDB.php" and that is what we've worked around in the rules. As such, any domain on [servername] using that script in the same way shouldn't generate a false-positive moving forward."
So it seems the answer (assuming your on an apache server of course) may be to modify the rules to allow full access for MMHTTPDB.php.
I hope that is of help to some.
