Fatal error: Uncaught Error: Call to a member function Prepare() on null in

Hello Ray
On my localhost pages using a mysqli recordset are working correctly.
but when I load these pages on to a remote server they fail with the error message
similar to:

Connection to MySQLi server successfully established.
Fatal error: Uncaught Error: Call to a member function Prepare() on null in
/homepages/37/d415519235/htdocs/net100test/WA_DB234/BFSN_full/webassist/mysqli/rsobj.php:185
Stack trace: #0 /homepages/37/d415519235/htdocs/net100test/WA_DB234/BFSN_full/A_Manufacture/results.php(13):

/homepages/37/d415519235/htdocs/net100test/WA_DB234/BFSN_full/webassist/mysqli/rsobj.php on line 185

Can you see where I am going wrong please?
Thank you
John

You have hand coded your connection and named it differently than Dreamweaver does. Your connection file is named conn1_i.php but your connection is named $connect and not $conn1_i like it would be if you had you used Dreamweaver to create it.

Many thanks Ray,

Changing $connect to $conn1_i resolved the problem!

Out of interest how does one get Dreamweaver to create the connection name, maybe I missed this using Navicat?

You create a connection from the Databases window in dreamweaver. It creates the connection file and names it. Go to window->databases and add a connection from there.

Hello Ray,
I have this error once again and cannot see why, I wonder if you can see where I went wrong.

It looks like you might be on a php7 server but have a standard mysql connection on the page. All database connectivity needs to be updated to mysqli to work on php7.

Hello Ray
Yes I am on a php7 server but I have updated the site using databridge234.

Hence the connection $conn1_i = mysql_connect($host_name, $user_name, $password, $database);
Is that not correct?

That looks like a standard mysql connection named conn1_i. It is not a mysqli connection.

Thanks Ray,
I am obviously not understanding how this connection should be made.
Is there a tutorial which explains this?

1) Open the Databases panel from either the Webassist menu or the Window menu.
2) Click the plus button and choose "New Dynamic MySQLi Connection"
3) Fill out the fields to create the connection
