How to create model and use in controller file
Deepak Tailor - Dec 07 2020
Models provide a way to interact with a specific table in your database. They come out of the box with helper methods for much of the standard ways you would need to interact with a database table, including finding records, updating records, deleting records, and more.
Create your model
<?php
namespace App\Models;
use CodeIgniter\Model;
class UserModel extends Model
{
}Access model in controller
protected $userModel;
public function __construct()
{
$this->userModel = model('App\Models\UserModel');
$db = db_connect('seller');
$this->userModel = model('Usermodel', true, $db);
}Configuration your model
protected $table = 'users';
protected $returnType = 'array';
protected $allowedFields = ['id','name'];find function in modeling data
Find function uses single row to match. This function checks the argument at the primary key. And it returns the value in the object or array format.
public function find_data()
{
$result = $this->userModel->find(1);
echo "<pre>";
print_r($result);
}
public function find_data()
{
$result = $this->userModel->find([1,3]);
echo "<pre>";
print_r($result);
}Find column value
To fetch the values of a column, we use the Find column function.
public function find_column()
{
$result =
$this->userModel->findColumn('salary');
echo "<pre>";
print_r($result);
}Find all records
public function find_all()
{
$result = $this->userModel->findAll();
echo "<pre>";
print_r($result);
}Find all records with where arguments
public function find_all()
{
$result = $this->userModel
->where('id',2)
->findAll();
echo "<pre>";
print_r($result);
}
public function find_all()
{
$result = $this->userModel
->where('id!=',2)
->findAll();
echo "<pre>";
print_r($result);
}Find first records
If the first record of the table has to be fetched, then we use the first function.
public function find_first()
{
$result =
$this->userModel->first();
echo "<pre>";
print_r($result);
}Find first records with where arguments
public function find_first()
{
$result =
$this->userModel
->where('id>',2)
->first();
echo "<pre>";
print_r($result);
