Problem indexing PDF

On those 6 documents, are there some which contain attachments ?

of course there is

Please try this on your WP database:

select ID, post_modified, post_parent, post_type from wp_posts
where ( post_status='publish' OR post_status='inherit' ) AND post_type='attachment'

It should detect your attachments

i have 13 attachments.
here is a copy of table content:
(10, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(18, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(19, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(20, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(21, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(22, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(23, ‘2015-02-25 16:04:11’, 13, ‘attachment’),
(24, ‘2015-02-25 16:04:14’, 13, ‘attachment’),
(25, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(35, ‘2015-02-27 12:23:45’, 8, ‘attachment’),
(40, ‘2015-02-27 12:23:45’, 0, ‘attachment’),
(43, ‘2015-02-26 17:14:36’, 45, ‘attachment’),
(44, ‘2015-02-27 10:18:49’, 45, ‘attachment’);

Everything looks all right.

i have french version of wordpress

The next step is debugging.

If you’re willing to do so, I’ll tell you were to look in the code.

let’s go

Let’s check that attachments are retrieved first.

In class-wp-solr.php, function get_attachment_body: set a debug breakpoint in first line in the try section.

Tell me what happens.

excuse me but how can i add this debug BreakPoint, i m using notepad++.

after running in debug mode, i add new page or load documents in the index?

You’ll ned a php IDE with debug capability.

Then, run a full re-index from WPSOLR.

some bad news :
27/02/2015 16:37:25: Fatal error: Call to undefined function plugin_dir_path()
27/02/2015 16:37:25: Xdebug server stopped C:\wamp\www\wordpress\wp-content\plugins\wpsolr-search-engine\class-wp-solr.phpScript break in file 3 at
27/02/2015 16:37:25: Session “phpd” started: file:///C:/wamp/www/wordpress/wp-content/plugins/wpsolr-search-engine/class-wp-solr.php

public function get_attachment_body( $extractQuery, $post )
both of extractQuery and post are null, is that normal?

Is your debugger ok now ? can you debug and watch some variables values ?
