Wordpress to ExpressionEngine, missing tags

Question

I'm currently using DataGrab to pull a WP blog into EE. It works for the most part, but I can't seem to get tags to work?

I added the Wordpress datatype to DataGrab (http://brandnewbox.co.uk/products/datatypes) and I see the "tags" section is looking for domain="tag", which the WP export has? Trying to get it to populate DevDemon Tagger field, but when checking import it looks like it's not seeing the tags at all?

Any suggestions greatly appreciated!!

EDIT: So I managed to get Wordpress tags pulled in by modifying the Wordpress datatype for DataGrab. Don't remember the line number, but for tags it's looking for domain="tag"but Wordpress exported it as domain="post_tag", so once I updated that I was able to get tags in. However, DataGrab still doesn't work with Tagger. So I could only import the tags into a text field, and then go into Tagger and import from the field.

This still doesn't completely solve the problem. Now the tags are in Tagger, but no longer attached to the post. So they're basically useless :(

Any thought/ideas on how to ge things re-attached in an automatic way? With 1,000's of post I'm not willing to go through and manually re-assign!

EDIT 2: I've since tried to use Solspace Tag as an alternative to see if it would work, unfortunately it does not. With DevDemon Tagger no error was returned, with Solspace Tag however I receive a php error:

Message: Undefined index: allow_subloop
Filename: fieldtypes/datagrab_tag.php

So still trying to figure this out. There are post on the DataGrab forum about this as well, so I know I'm not alone: http://brandnewbox.co.uk/forums/viewthread/858/, I also submitted my own post here: http://brandnewbox.co.uk/forums/viewthread/927/

I will update this post if I manage to get a solution figured out...

Answer 1

DataGrab doesn't currently have support for the Tagger field type.

However DataGrab does have support for Solspace Tag which may provide the correct functionality for you without having to manually update.

Tag isn't free, but Solspace offer a 30-day money back guarantee so if it doesn't work you should be able to get a refund.

Answer 2

The developer of DataGrab emailed me the solution. I figured I would post it here so that anyone else who may have this problem down the road is able to solve it!

First, you need to update the Wordpress plugin as described in my original post. Then copy this bit of code and save it as "datagrab_tagger.php" and place inside the DataGrab "fieldtypes" folder:

<?php

/**
 * DataGrab Tagger fieldtype class
 *
 * @package   DataGrab
 * @author    Andrew Weaver <[email protected]>
 * @copyright Copyright (c) Andrew Weaver
 */
class Datagrab_tagger extends Datagrab_fieldtype {

    function prepare_post_data( $DG, $item, $field_id, $field, &$data, $update = FALSE ) {

        $data[ "field_id_" . $field_id ]["tags"] = array();

        // Can the current datatype handle sub-loops (eg, XML)?
        if( $DG->datatype->datatype_info["allow_subloop"] ) {

            // Check this field can be a sub-loop
            if( $DG->datatype->initialise_sub_item( 
                $item, $DG->settings["cf"][ $field ], $DG->settings, $field ) ) {

                // Loop over sub items
                $tags = array();
                while( $subitem = $DG->datatype->get_sub_item( 
                    $item, $DG->settings["cf"][ $field ], $DG->settings, $field ) ) {

                        $tags[] = $subitem;

                    }
                    $data[ "field_id_" . $field_id ]["tags"] = $tags;

                }

        }

    }

}

?>

This will allow you to import Wordpress tags into DevDemon Tagger!
