Hi,
I am using Zend_Search_Lucene (from 0.93) in my php app (running php
5.2.1) and trying to display the results from multiple documents in my
index:
View Code:
Code:
<?php if(!empty($results)){
//pr($results);
echo '<h1>Search results: found '.count($results). ' document(s):</h1>';
foreach($results as $result){
echo 'Score: '.$result->score.'<br />';
$result = $result->getDocument();
if ($result->getFieldValue('news_title')){
echo 'News Title: '.$result->getFieldValue('news_title').'<br />';
}
else { echo "There are no news items matching your query";}
}
} else {
echo '<h1>There are no results to display</h2>';
}
?>
This works if the results object contains a field called 'news_title'
but if it doesn't, i get:
Code:
Fatal error: Uncaught exception 'Zend_Search_Lucene_Exception' with
message 'Field name "news_title" not found in document.' in

on line 94
My question is therefore - how can I check for the existence of a field
in the results? My index contains fields for news, brochures, videos,
galleries etc. so i want a dynamic search page which only tries to
display matching news articles if there are any!
many thanks for any replies.
luke.
