Update multiple Rows in Codeigniter - codeigniter

Question

I have been looking around but I have not found an answer yet. Kindly help if you know the answer.
How do you update multiple rows in CI?
In my MySQL:
I have column names:
ID, Settings Name, Settings Value ( Settings Name is Unique )
I have the ff Data:
ID = 1, Settings Name = "Hello" , Settings Value = "True"
ID = 2, Settings Name = "World", Settings Value = "Good"
and more ...
I also have a form that gets the Settings Value but I am not sure how to update it on the DB. How to update the True for the Hello being the Settings Name and update the Good for the World.
I heard about insert_batch() but is there an update_batch()?

Answer 1

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.

Answer 2

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

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
