Update a row, but insert if row doesn't exist in codeigniter

Question

I want to do an insert of row in a table, like this:

$this->db->update_batch($this->table_name, $update, \'image_id\');

if ($this->db->affected_r         


        

Answer 1

I think what you're looking for is INSERT IGNORE INTO. Unfortunately, Codeigniter doesn't have an equivalent Active Record function. A discussion on the Codeigniter forums and this similar SO question suggest a method like this:

foreach ($update as $update_item) {
    $insert_query = $this->db->insert_string($this->table_name, $update_data['name']);
    $insert_query = str_replace('INSERT INTO','INSERT IGNORE INTO',$insert_query);
    $this->db->query($insert_query);  
}

Also note that the image_id must be UNIQUE.
