Inserting array of Ids in Codeigniter - php

Question

I'm trying to insert two rows but the id of every row is in the same array, how can I insert correctly?
Because I tried by this way but only insert me the first id.
$sql = "
INSERT INTO cars(car, price, createdDate, createdBy)
VALUES (".$this->db->escape($ids).",
".$this->db->escape($price).",
NOW(),
".$this->session->userdata('admin_id').")";
mysql_query($sql);
echo ($sql);
This is what I get:
INSERT INTO cars (car, price, createdDate, createdBy)
VALUES ('217450,217449', '15', NOW(), 150)
In car I want to insert the price, createdDate and createdBy on the two car Ids 217450,217449.
Thank you in advance.

Answer 1

$ids = "217450, 217449";
$id_explode = explode(",", $ids);
foreach($id_explode as $id)
{
$sql = "
INSERT INTO cars(car, price, createdDate, createdBy)
VALUES (".$this->db->escape($id).",
".$this->db->escape($price).",
NOW(),
".$this->session->userdata('admin_id').")
";
mysql_query($sql);
echo ($sql);
}
But I recommend you not to use raw SQL queries as it is vulnerable to SQL injection.Hence, Use CI's active record:
$ids = "217450, 217449";
$id_explode = explode(",", $ids);
$insert_batch = array();
foreach($id_explode as $id)
{
$arr = array(
'car' => $id,
'price' => $price,
'createdDate' => NOW(),
'createdBy' => $this->session->userdata('admin_id'),
);
$insert_batch[] = $arr;
}
$this->db->insert_batch('cars', $insert_batch);

Answer 2

Use PHP function explode:
$ids= explode(',', $ids);
foreach($ids as $id)
{
$sql = "INSERT INTO cars(car, price, createdDate, createdBy)
VALUES (" . $this->db->escape($id) . ", " . $this->db->escape($price)
. ", NOW(), " . $this->session->userdata('admin_id') . ")";
mysql_query($sql);
}

Answer 3

If you use ids as array like
$ids = array('217450','217449');
$sql = "
INSERT INTO cars(car, price, createdDate, createdBy)
VALUES ";
foreach($ids as $id){
$sql .=(".$this->db->escape($id).",
".$this->db->escape($price).",
NOW(),
".$this->session->userdata('admin_id')."),";
}
mysql_query($sql);
echo ($sql);
Now it will create query
INSERT INTO cars (car, price, createdDate, createdBy)
VALUES ('217450', '15', NOW(), 150),('217450', '15', NOW(), 150);
