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.
