I have this code i need to use to get results from a database, I'm on codeigniter. This is how the query looks like,
$this->db->select('*');
$this->db->where('broadcast_id', $bid);
$query = $this->db->get('ih_noticeboard');
$result = $query->result();
if($query->num_rows() < 1){
$data = "no feed ";
}else{
$data = $result;
}
the $bid
in the where clause is got from this code,
$this->db->select('broadcast_id');
$this->db->where('broadcast_subscribers', $id);
$query = $this->db->get('ih_broadcastors ');
if($query->num_rows() < 1){
$data = "user not subscribed to any broadcasting";
}else{
$ress = $query->result();
foreach ($ress as $row){
$bid = $row->broadcast_id;
}`
Now the select uses only one $bid, how can I use the $bid as an array?
It's quite simple . just use $this->db->where_in('broadcast_id', $bid);
instead if $this->db->where('broadcast_id', $bid);

Wouldn't it be better to have one query to get the feeds?
$this->db->select("ih_noticeboard.*");
$this->db->from("ih_noticeboard");
$this->db->join("ih_broadcastors", "ih_noticeboard.broadcast_id = ih_broadcasters.broadcast_id");
$this->db->where("ih_broadcastors.broadcast_subscribers", $id);
$result->db->get()->result();
Assuming you want to select in the table where
name='jane' and broadcast_id=2 #as an example
$bid=array(
'name'=>'jane',
'broadcast_id'=>'2'
)
$this->db->where($bid);
$this->db->from($table_name);
$query = $this->db->get()->result_array();
return $query;
Please notice that the $bid as array must be formated to suite the next database table to be queried. You can do this using foreach loop Eg
foreach ($ress as $row){
$bid = array(
'name'=>$row['name'],
'broadcast_id'=>$row['id']
);
