Answer 1

Here is a simple php code for perform this operations.

<?php
function basic_update($uwi='') {
$this->load->database();
$data = array(
'ID' => 1,
'Settings Name' => 'Hello',
'Settings Value' => 'True'  
);
$this->db->where('ID', '1');
$this->db->update('<table name>', $data);
$data1 = array(
    'ID' => 2,
    'Settings Name' => 'World',
    'Settings Value' => 'Good'
    );
    $this->db->where('ID', '2');
    $this->db->update('<table name>', $data1);
}

In $this->db->where('ID', '1'); ID is your table field and 1 is the value. In array first parameter will contain the table name, the second parameter is an associative array of values

There is indeed an update_batch() method available in CodeIgniter already.

You can use it your example like so:

$data = array(
    array(
        'ID' => 1,
        'Settings Name' => 'Hello',
        'Settings Value' => 'True'
    ),
    array(
        'ID' => 2,
        'Settings Name' => 'World',
        'Settings Value' => 'Good'
    )
);
$this->db->update_batch('tableName', $data, 'id'); 

So what you have is an array of arrays, the children basically hold the data for each row in the database. The first parameter for update_batch() is the name of the database table, the second is the $data variable and the third is the column you want to use in the WHEN clause.

Answer 3

Are you using Active record?

Yes there is an update batch: $this->db->update_batch();

$data = array(
array(
  'ID' => 1 ,
  'Settings Name' => 'Hello' ,
  'Settings Value' => 'True'
),
array(
  'ID' => '2' ,
  'Settings Name' => 'World' ,
  'Settings Value' => 'Good'
)
);    

$this->db->update_batch('mytable', $data, 'where_key'); 

From the documentation:

The first parameter will contain the table name, the second is an associative array of values, the third parameter is the where key.
