$data['listingmeta']=$this->Classifieds_model->addmeta($listingid,$metakey,$metavalue,$data);
here is the model code
function addmeta($listingid,$metakey,$metavalue,$data2)
{
$this->load->database();
$data = array(
'classifieds_id' => $listingid ,
'meta_key' => 'location' ,
'meta_value' => 'mangalore'
);
foreach($data2['listingmeta'] as $meta)
$this->db->insert('classifieds_meta',

'meta_key' => 'location' ,
'meta_value' => 'mangalore'
)
);
}
but the above code doesnt work, please can someone help?

Answer 1

The propest way, it's better to avoid SQL commands in loops :
$insert_batch = array();
for($i=0; $i<count($); $i++)
{
$insert['classifieds_id'] = $listingid;
$insert['meta_key'] = $metakey[$i];
$insert['meta_value'] = $metavalue[$i];
$insert_batch []= $insert;
}
$this->db->insert_batch('classifieds_meta', $insert_batch);

1) Create a simple model function just to insert data array. (always try to frame your model functions such that they can be re-used)
function addmeta($data)
(
$this->db->insert('classifieds_meta', $data);
)
2) Now send the required array to the model through the Controller below
array(
'classifieds_id' => $listingid ,
'meta_key' => 'location' ,
'meta_value' => 'mangalore'
)
$listingid=145;
$metakey=array();
$metavalue=array();
if($data['submitlisting'])
{
if($vehicle_make != "")
{
$metakey[]="vehicle_make";
$metavalue[]=$vehicle_make;
}
if($vehicle_mileage != "")
{
$metakey[]="vehicle_mileage";
$metavalue[]=$vehicle_mileage;
}
if($vehicle_year != "")
{
$metakey[]="vehicle_year";
$metavalue[]=$vehicle_year;
}
$insert = array();
for($i=0; $i<count($metakey); $i++)
{
$insert['classifieds_id'] = $listingid;
$insert['meta_key'] = $metakey[$i];
$insert['meta_value'] = $metavalue[$i];
$this->Classifieds_model->addmeta($insert);
}
}

Answer 3

can try this code into controller:
$ex=count($this->input->post('ex'));
$count =count($this->input->post('ex'));
$data2 =array();
for($i=0; $i<$count; $i++)
{
$data2[] = array(
'ex' => $ex[$i],
);
}
$this->db->insert_batch('table', $data2);
