I have been, for days, trying to add Zend_lucene search to my cake
site. It works perfectly when I use it in my controller (i.e. without
the component) but I am not having much luck turning it into a
component so that it will be available to all of my controllers. This
is a site-wide search and the form is to appear on every page.
The error I am getting is: Fatal error: Call to a member function query
() on a non-object in C:\wamp\www\test\app\controllers\components
\lucene.php on line 19
(The file lucene.php is shown in section 3, below.)
I realise that this is likely to be more of a PHP error than a cake
one, but I am getting the error, I believe, because of CakePHP's file
structure and that I have forgotten to do something in the component
or vendor sections (making it very much a Cake issue, for me).
Below is what I've done.
I have extracted the Zend library files into the vendors folder so the
structure is:
1)
- app/vendors/Zend/Search/Lucene/
- app/vendors/Zend/Search/Lucene.php
- app/vendors/Zend/Search/Exception.php
2)
In my controller that I want to access this component, I have declared
var $components = array('lucene');
3)
The component, lucene.php, contains the following code:
<?php
$path = APP.'/vendors';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);
App::import('Vendor','lucene',array('file'=>'Zend/Search/
Lucene.php'));
class LuceneComponent extends Object
{
var $controller = null;
function startup(&$controller)
{
$this->data = $controller;
}
function build()
{
$index = Zend_Search_Lucene::create('/tmp/my-index');
//***** The line below causes the error******
$company_rs = $this->controller->query('MY VALID SELECT
STATEMENT');
//... more irrelevant code not included
}
}
?>
The query itself (not shown) is valid, so it's not the SQL.
What have I done, or not done, to get this to work.
Any help would be much appreciated.
