Indexing PDF attachments not working.

Interesting:
I an open the above link from the above error in a browser and get an actual document
(URL is not externally reachable.)

You have to find why php can’t.

Can you replace get_the_guid by get_attached_file

It will load the attachment from its file rather than from its url.

Where insert (class/line?)

Same class. Replace, not insert.

$extractQuery->setFile( preg_replace( ‘~^http(s)?://’ . $_SERVER[‘SERVER_NAME’] . ‘~i’, $_SERVER[‘DOCUMENT_ROOT’],get_attached_file( $post->ID ) ) );

Yes, replace this line by:

$extractQuery->setFile( get_attached_file( $post->ID ) );

//$extractQuery->setFile( preg_replace( ‘~^http(s)?://’ . $_SERVER[‘SERVER_NAME’] . ‘~i’, $_SERVER[‘DOCUMENT_ROOT’]$

$extractQuery->setFile( get_attached_file( $post->ID ) );

no change in results. I have disabled all other plugins.

12 posts/pages get indexed, but not the attachment.

what error is displayed now ?

No error, but I had to comment out the trap.

Putting back in as:

$body = str_replace( ‘\n’, ‘ ‘, $body );
} catch ( Exception $e ) {
// $body = ”;
throw new Exception(‘Attachment error on file ‘ . get_the_guid( $post->ID ) . “:
” . $e->getMessage());

SHOULD THIS NOW BE RATHER:
get_attached_file( $post->ID ) . “:
” . ?

yes

No error.
However, the trap is blocking indexing altogether (zero documents index)

Commenting out the trap allows 12 documents to index again (but not the attachments).

Please replace your code by this one:

public function get_attachment_body( $extractQuery, $post ) {
		$solr_options = get_option( 'wdm_solr_conf_data' );

		// Set URL to attachment
		$extractQuery->setFile( get_attached_file( $post->ID ) );
		$doc1 = $extractQuery->createDocument();
		$extractQuery->setDocument( $doc1 );
		// We don't want to add the document to the solr index now
		$extractQuery->addParam( 'extractOnly', 'true' );
		// Try to extract the document body
		try {
			$client   = $this->client;
			$result   = $client->extract( $extractQuery );
			$response = $result->getResponse()->getBody();
			$body     = preg_replace( '/^.*?\<body\>(.*?)\<\/body\>.*$/i', '\1', $response );
			$body     = str_replace( '\n', ' ', $body );
		} catch ( Exception $e ) {
			throw new Exception( 'Error on attached file ' . get_attached_file( $post->ID ) . ": <br/>" . $e->getMessage() );
		}

		return $body;
	}

You should see an error message triggered by the first attachment.

Replaced code with the above.
Result: no error message, but no indexing either . ..
