Inserting array of data in database - php

Question

I have two arrays of values:
First array contain user id's:
Array ([0]=>1 [1]=>2 [2]=>3 [3]=>4 [4]=>5 [5]=>6)
Second array contain attendance status:
Array([0]=>Present [1]=>Absent [2]=>Absent [3]=>Present [4]=>Absent [5]=>Present)
I want to insert these values in the database in separate rows like this:
U_id Status
1 Present
2 Absent
3 Absent
4 Present
5 Absent
6 Present
Currently, I am using this code to insert values in database.
My Controller Code:
public function usr_att(){
if(isset($_POST['submit'])){
$uid = $_POST['uid'];
$status= $_POST['stat'];
$id = implode("," , $uid );
$status = implode("," , $status );
$data = array (
'u_id' => $id,
'status' => $status
);
$this->db->insert('attendence' , $data);
redirect("usr/usr_list", "refresh");
}
}
But this code inserts data like this:
U_id Status
1 Present,Absent,Absent,Present,Absent,Present
How can I insert these values in separate rows using CodeIgniter?

Answer 1

Simply you can do like this
public function usr_att()
{
if(isset($_POST['submit']))
{
$uid = $_POST['uid'];
$status = $_POST['stat'];
foreach ($uid as $key => $item)
{
$data = array (
'u_id' => $item,
'status' => $status[$key]
);
$this->db->insert('attendence' , $data);
}
redirect("usr/usr_list", "refresh");
}
}

For your intended purpose, once you have the values for $uid and $stat in an array, then you could do this:
<?php
// You have your u_id values in an array
$uid = array('1','2','3','4','5','6');
// You have your status values in an array
$stat = array('Present', 'Absent', 'Absent', 'Present', 'Absent', 'Present');
// As long as the number of u_id values and status values are the same
if( count($uid) == count($stat) )
{
// Use the count of uid values and loop through
for( $x = 0; $x <= count($uid) -1; $x++ )
{
// Entering each on in the database
$this->db->insert('attendence', array(
'u_id' => $uid[$x],
'status' => $stat[$x]
));
}
}
