Table name as Variable in Model Codeigniter - php

Question

Is it possible that i can pass some variable to the model in table name?
I have a module that creates Customers.
Now for each Customers we create a separate table.
The Customers has a login and logout credentials.
Now for whenever a customer is created i can't always create a new model and pass it name there.
So i want that it gets dynamically, I am not sure how i can do it.
For each customer there will be one separate table.
Now i want to create a model for login, but what should i pass in the table name,it should be dynamic right?
What should be the mysql schema to get this done?
This my sample Model code:
class Customer_User_M extends MY_Model
{
protected $_table_name = 'customer1';
protected $_order_by = 'name';
public function __construct()
{
parent::__construct()
}
}
The Customer Table:
CREATE TABLE IF NOT EXISTS `customer1` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`site_key` varchar(50) NOT NULL,
`display_name` varchar(100) NOT NULL,
`ext` varchar(15) NOT NULL,
`auth_user` varchar(100) NOT NULL,
`password` varchar(128) NOT NULL,
`base_ini_id` varchar(50) NOT NULL,
`comments` varchar(200) NOT NULL,
`custom_ini_filename` varchar(50) NOT NULL,
`email` varchar(50) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ;

Answer 1

You can simply make a function in the model and put the code of create table in the function and pass dynamic table name in the function from controller like below....
Model function code:
function access_customer_table($table_name)
{
//put ur select query here with table name in FROM clause will be $table_name
}
and call this model function in your controller after load the model... and put your table name as argument...
like :
$this->load->model('Customer_User_M');
$this->Customer_User_M->access_customer_table('new_customer_table_name');
Please correct syntax if needed.. let me know if anything wrong in the logic...

I tried to set the table name after loading the model. Just worked for me.
$this->load->model('customer_model','customer');
then,
$customer->table_name = "customer_xxx";

It is better to save common customer details in a customer table and create another tables to store different data of customers with different fields having foreign key customerid.
Here, if you want to pass dynamic tablename to model then you need to predefine all table names as an associative array with key-value pair.Then you can pass desired key-value to model.It can be implemented using a library.So that you can use it all your controllers.
