Create Table in MySQL database. My database name is "ABC" and my table name is "country".
Database connectivity. You must first edit the file database:

  • Autoload the database.
  • The Model.
  • The Controller.
  • Output.

For insert data in MySQL using CodeIgniter first we have to create a table in data base:

  • SQL Query
  • Crud. php Path: codeIgniter\application\controllers\Crud. php.
  • Crud_model. php Path: codeIgniter\application\models\Crud_model. php.
  • insert. php Path: codeIgniter\application\views\insert. php.

Hooks in CodeIgniter allow you to access and modify the framework's inner workings without having to edit the core files. When you execute CodeIgniter, it follows a precise execution procedure that is depicted on the Application Flow page.

  • public function update_row(){
  • $update_rows = array(
  • 'name' => 'rincky',
  • 'address' => 'India',
  • 'contact' => '98545785',
  • 'department' => 'IT',
