Selecteer eerst alle image_id uit de tabel.
$data = $this->db->select(`image_id`)->get($this->table_name)->result_array();
Vermeld image_id in een array.
$image_ids=array();
foreach($data as $key => $value):
$image_ids[$key]=$value[`image_id`];
endforeach;
$update = array(
array('image_id' => 1, 'name' => 'Party Gustav'),
array('image_id' => 2, 'name' => 'Peter'),
array('image_id' => 3, 'name' => 'Lisa')
)
Controleer of de image_ids bestaan:
$update_query= $this->db->where_in(`image_ids`,$image_ids)
->get($this->table_name)->result();
if($update_query->num_rows() > 0):
$this->db->update_batch($update,$this->table_name);//update if ids exist
else
$this->db->insert_batch($update,$this->table_name);//insert if does not exist
endif;
