How to get number of rows affected, While executing mysql query PHP

<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
mysql_select_db('mydb');
/* this should return the correct numbers of deleted records */
mysql_query('DELETE FROM mytable WHERE id < 10');
printf("Records deleted: %d\n", mysql_affected_rows());
/* with a where clause that is never true, it should return 0 */
mysql_query('DELETE FROM mytable WHERE 0');
printf("Records deleted: %d\n", mysql_affected_rows());
?>

Inserting multiple rows mysql in codeigniter

if your php version>=5.4 it should work.

You may try this

if ($_POST) { $row_ids=$this->input->post('id'); $desc=$this->input->post('desc'); $spaces=$this->input->post('space'); $prices=$this->input->post('price'); $totals=$this->input->post('total'); $data = array(); for ($i = 0; $i < count($this->input->post('id')); $i++) { $data[$i] = array( 'row_id' => $row_ids[$i], 'desc' => $desc[$i], 'space' => $spaces[$i], 'price' => $prices[$i], 'total' => $totals[$i], 'code' => time() ); } $this->Home_model->create($data); }
