why models are not loading in autoload

i know the basic concept model name should start with small letter in autoload

i need a detailed answer

You're a bit skimpy on details supporting your claim that models aren't autoloaded.

application/config/autoload.php ...
$autoload['model'] = array('customer');

tells CodeIgniter to look for the class "Customer" inside application/models/Customer.php

Note the UCfirst convention.

controller--------

<?php if (!defined('BASEPATH'))exit('No direct script access allowed');


class Admin extends CI_Controller {

function __construct() {
parent::__construct();
$this->load->database();
$this->load->library('session');

}


function vacancy($param1 = '', $param2 ='', $param3 =''){

if ($param1 =='insert'){

$this->load->vacancy_model->insertVacancyFunction();
$this->session->set_flashdata('flash_message', get_phrase('Data saved successfully'));
redirect(base_url(). 'admin/vacancy', 'refresh');

}

if ($param1 == 'update'){


$this->vacancy_model->updateVacancyFunction($param2);
$this->session->set_flashdata('flash_message', get_phrase('Data updated successfully'));
redirect(base_url(). 'admin/vacancy', 'refresh');

}

if($param1 == 'delete'){


$this->vacancy_model->deleteVacancyFunction($param2);
$this->session->set_flashdata('flash_message', get_phrase('Data deleted successfully'));
redirect(base_url(). 'admin/vacancy', 'refresh');

}


$page_data['page_name'] = 'vacancy';
$page_data['page_title'] = get_phrase('Manage Vacancy');
$page_data['select_vacancy'] = $this->db->get('vacancy')->result_array();
$this->load->view('backend/index', $page_data);

}

}

model------>

To load a model in a Controller it is done like this.

PHP Code:

// load in a controller'
$this->load->model('modelName', 'aliasName'); 


Also to access a method in the controller.

PHP Code:

// load in controller and access method.
$this->load->('vacancy_model');
$this->vacancy_model->insertVacancyFunction(); 


Give that a try

files are not loading if i did like above 

I would re-download CodeIgniter and install a clean new copy and see if that will fix it.

Otherwise it sounds like something is corrupted in your directory structure.

I always use the development branch and I use both CI 3 and CI 4 with not problems.

i just created two model with different name one is loading without error and another one is not and all the sytaxes are correct may i know what is the problem

Make sure your models are in the application/models folder and start with a capital letter.
When loading a model with $this->load->model( ... ) don't use a capital letter.
So, it's perfectly ok to load the Vacancy_model.php with $this->load->model('vacancy_model');
To refer to methods (functions) inside the model: $this->vacancy_model->function_name();
