QuoteInto to with multiple parameters

hi

I need to query the database with 2 parameters from a URL :

http://mainevent.com/admin/galleries...d/1/type/venue

Code:

public function getGalleryByIdType($requestType="", $requestID="")
                {
                               if($requestType ="event'){
                               
                                  $db        = Zend_Registry::get('db');
                                   $sql       = $db->quoteInto("SELECT g.GalleryName, e.EventName
                                                   FROM Galleries  g  
                                                   LEFT JOIN EventGallery eg ON eg.GalleryID = g.GalleryID
                                                   LEFT JOIN Event e On e.EventID = eg.EventID
                                                   WHERE g.Type=? AND g.GalleryID=?" , $requestType,$requestID);
                       
                                                                                         
                                  $query     = $db->query($sql);
                               
                                  $results   = $query->fetchAll();
                                 
                                  return $results;
                            }
               
               
                }

It seems the quoteInto function only accepts a single parameter. It returns an empty array with no results. And the function doesnt support supplying parameters as an array of values. I came across this article:

Modifying Zend_Db_Adapter_Abstract::quoteInto to accept multiple question marks at Amikelive | Technology Blog

And this guy recommends modifying the function definition. I just want to know if this is the appropriate route to solving this. Thanks

The other option is to use bound parameters by passing the second parameter to query(). So you don't even need quoteInto(). Like this:

Code:

...
$sql       = 'SELECT g.GalleryName, e.EventName
                ...
                WHERE g.Type = :gType AND g.GalleryID = :gGalleryId';
                
                $query     = $db->query($sql, array(
                    'gType' => $gType,
                    'gGalleryId' => $gGalleryId,
                ));

You can have as many bound parameters as you want, unfortunately you can't use the same one multiple times in the query (unless that's changed since last I looked).

Thanks but then i am not quoting any of those values! Doesnt that open me to sql injection attacks?

Nope, the bound parameters are inserted by creating a prepared statement and executing it (or a facsimile of, if prepared statements are not available in your database/adapter).

Tekerson - i have a question related to what you said

[PHP]
$arr = array('some_id' => (int)$some_id, 'name' => $name, 'name2' => $name2);
$this->db->update('table', $arr, 'id ='.(int)$id);
[/PHP]

I am only doing trim() on $name and $name2, is this query safe? How should i escape the vars? Is Zend_Db doing it automagically?

Thanks!
