Re: Inner Join cakephp

Have you already populated the second table? In case not you could use a hasOne or hasMany association, but you might have to change the layout of the table itself.

I have these 2 tables: cd_biblio (which contains a list of books) and cd_bibliotem (which contains only the id of book and id of tag).
I want to make a query where the user can choose also the tag of a book (in both tables the tags are numeric).
In the cd_biblios controller I add:

App::import('Model', 'CdBibliotem');  $CdBibliotem = new CdBibliotem();

I made the queries for cd_biblio table in this way:

// General query  $conditions = array(      'editore LIKE' => "%$e%",      'titolo LIKE' => "%$t%"  );

And then for example: 

if (!$anno)          $conditions[] = array('anno <=' => "$anno2");            if (!$anno2)          $conditions[] = array('anno >=' => "$anno");

Or: 

if (isset($menu)&&$menu!='')          $conditions[]=array('classe LIKE' => "%$menu%");

Now I need to do a inner join between these 2 tables to get all the books with a specific tags. 
I save tags in string, so I use: 
SELECT ... WHERE tags IN ('$tags'); 
But I can't make a inner join using $conditions. 

I tried something like this: 

$tem = $CdBibliotem->query("SELECT * FROM cd_biblio INNER JOIN cd_bibliotem ON cd_biblio.codiceBiblio = cd_bibliotem.codiceBiblio WHERE codiceTematica IN ('$tematiche')");   $tem = Set::extract($tem, '{n}.cd_biblio');  $conditions[]=array('cd_biblio.codiceBiblio IN (?)' => '$tem');     

But it's not working. (I'm using ver 1.2)
