In Wordpress, Record insertion into table is quite simple.
1. Create an Object of $wpdb;
2. Set the data in an Array.
3. Set the table name.
4. Use insert function to insert record.
5. In insert function, first argument is table name and Second argument is array.
See Example Below:
global $wpdb;
$tableName = $wpdb->prefix . "users";
$saveFieldArray=array(
'user_login' => 'mylogin',
'user_pass'=>'pass',
'user_nicename' => 'Poonam',
'user_email' => 'email@no-spam.com',
'user_registered' => date('Y-m-d H:i:s',time()),
'user_status' => '1',
'display_name' => 'Arun Kumar');
//Insert Into Database
$wpdb->insert( $tableName, $saveFieldArray);
//get the last inert Id
$lastInsertId = $wpdb->insert_id;
