Importing From Roller

You can fairly easily import data from Apache Roller using the MovableType import script.

  1. Export your blog from the Roller database for importing into WordPress.
  2. Copy photographs, images, graphics, video, and all content files to the appropriate directories in your WordPress site server.
  3. Modify the $user, $oldresources, $newresources, and $connection variables in the beginning of the script below script and place it on your server where PHP execution is allowed.
  4. Execute the script. This will create a "dump" of your Roller blog content into a MovableType Import format.
  5. Use wget to store it into file.

Then follow the instructions for Importing from Movable Type to WordPress.

The following scripts should work for Roller pre-2.0 release. After Version 2.0, the comment table is changed to roller_comment. Change the select statement to roller_comment.

Exporting Roller Database from postgresql

For Roller using the postgresql database, copy the following script carefully and place it in a text editor and save it with an appropriate name as a PHP file. Upload it per the instructions above to your Roller server.

<html>
<head>
<title>Roller export</title>
</head>   
<body>
<?
// assumes that Roller is running on postgresql
// it also assumes that there is only one blog for user
// the character set used by Roller is utf8, but this seems to suit at least
// WordPress just fine, so no conversions done
// just modify the script, store it somewhere where php execution is allowed
// and wget the url
//
// provided by Madis Kaal 
//
$user = "bloguser";
// in entry body, all occurrencies of $oldresources are 
// replaced with $newresources
$oldresources = "/resources/bloguser/";
$newresources = "http://somesite/wp-content/";
// define your database connection here
// dbname is name of database
// usually, it is on localhost
// password is for accessing the db
// and user is username for it
$connection = pg_connect("dbname=dbname host=localhost password=dbpassword user=dbuser");

// -- this is it, no changes should be needed below -------------------------------
// get ID for user
$result = pg_Exec($connection, "select id from rolleruser where username='".$user."'");
$uid=pg_result($result,0,0);
// get ID for site
$result = pg_Exec($connection,"select id from website where userid='".$uid."'");
$siteid=pg_result($result,0,0);
// get all entries for this site
$entries= pg_Exec($connection,"select id,title,text,pubtime,categoryid,allowcomments,publishentry from weblogentry where websiteid='".$siteid."' order by pubtime");
// dump all entries
echo "--------\n";
for($i=0; $i<(pg_numrows($entries)); $i++)
{

  // do it in query, but I'm a complete C-head
  $resultRow = pg_fetch_array($entries, $i);
  $c=$resultRow["categoryid"];
  $cat=pg_result(pg_Exec($connection,"select name from weblogcategory where id='".$c."'"),0,0);
  // dump metadata first  
  echo "PRIMARY CATEGORY: ".$cat."\n";
  echo "AUTHOR: ".$user."\n";
  echo "TITLE: ".$resultRow["title"]."\n";
  $c=$resultRow["pubtime"];
  // convert YYYY-MM-DD hh:mm:ss.ms to MM/DD/YYYY hh:mm:ss

}
pg_close($connection);
