Hi i am using select2 jquery plugin to insert multiple values to a drop down but when i am trying to update i am facing problem can anyone help me out in showing the right way of doing this 

<?php 
    $cats = explode(',',$r['keyword_whomtoteach']);
    foreach($cats as  $vald) {
        foreach($keyword as $key=>$keywords) { 
            if ($vald == $keywords->keyword_id) { ?>                         
                <option value="<?php echo $keywords->keyword_id; ?>" <?php { echo "selected"; }  ?>><?php echo $keywords->keyword_name; ?></option> <?php } else { ?>
                <option value="<?php echo $keywords->keyword_id; ?>"><?php echo $keywords->keyword_name; ?></option>  
<?php        }

        $(".selectmultiple").select2();
    });
</script>

public function keyword_all()
{
    $this->db->select('*')->from('keywords');
    $query=$this->db->get();
    return $keyword = $query->result();
}

I'm not sure if this solves your problem but this could make things a bit quicker - it's certainly a lot neater.

<?php 
    $cats = explode(',', $r['keyword_whomtoteach']);
    foreach($cats as $vald) {
        foreach($keyword as $key=>$keywords) { ?>                    
            <option value="<?php echo $keywords->keyword_id; ?>" <?=($vald == $keywords->keyword_id ? 'selected' : '')?> ><?php echo $keywords->keyword_name; ?></option> 
<?php   }
    }
?>
