Question

I have a call to a model which is just a standard class (not extending zend_db_table). I am doing a select and want to have the possibility of excluding a set of ids which which would be passed in as a variable.

I curently have the following:

public function getItemsBySection($section, $excluded_ids=null){
    //handle this as special case (although only case at this point)

    if(is_array($excluded_ids) and count($excluded_ids)>0){
        $x=1;
        foreach($excluded_ids as $key=>$value){
            if($x==1){
                $not_in=$value;
            }else{
                $not_in.=','.$value;
            }
            $x++;
        }
    }

    if($section=='feed_supplies'){
        $sql='select * from items where is_feed_supply=1';
        if($not_in){
            $sql.=' and id not in ('.$not_in.')';
        }
    }

    echo $sql . '<br/>';

    $results=$this->_db->fetchAll($sql);

but was wondering if there is a way to use Zend_Db_Expr or some other concstruct to handle the exclusion of certain items? I’m not error handling like if it is an integer etc…

I personally am not that big of a fan of the zend_db_select syntax but could be persuaded if it fixes things like this (want to see Doctrine2).

thanks

I’m not sure about using Zend_Db_Expr, but you don’t need that first loop at all to build your $not_in value.

$not_in = implode( ',', $excluded_ids );
