How to create custom helper in CodeIgniter

In this article, We will discuss how to create custom helper in CodeIgniter. CodeIgniter allows the creation of a custom helper. So we can easily create a custom helper. we will take the latest example and learn how to use a custom helper in CodeIgniter. so let’s follow the below step.

Create the helper file.

first, we will create a helper file in the “application/helpers/commonfunction_helper.php”. put some code in this file. here in this file. we will get the student all detail using the custom helper function.

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

	/*
	 * get_all_rows
	 *
	 */
	function get_all_student_rows()
	{
		$CI =& get_instance();
		$CI->db->select();
		$query = $CI->db->get('students');
		//echo $CI->db->last_query();die;
		return $query->result_array(); // This will return array
	}
	
?>

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

* get_all_rows

function get_all_student_rows()

{

$CI =& get_instance();

$CI->db->select();

$query = $CI->db->get('students');

//echo $CI->db->last_query();die;

return $query->result_array(); // This will return array

}

Load The Custom helper

Now, we will load the custom helper so we will open the application/config/autoload.php file and add the helper name to the helper array.

/*
| -------------------------------------------------------------------
|  Auto-load Helper Files
| -------------------------------------------------------------------
| Prototype:
|
|	$autoload['helper'] = array('url', 'file');
*/
$autoload['helper'] = array('commonfunction_helper');

| -------------------------------------------------------------------

| Auto-load Helper Files

| -------------------------------------------------------------------

| Prototype:

| $autoload['helper'] = array('url', 'file');

$autoload['helper'] = array('commonfunction_helper');

How to use the custom helper function in Controller or Views.

now, we can use the custom helper function in Controller or Views. we can get the student detail in Controller or Views using the call get_all_rows helper function.

Controller Example

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

class Student extends CI_Controller {
    function __construct()
    {
        parent::__construct();
    }
    public function index()
    {
      $student_detail = get_all_student_rows();
      echo "<pre>";
      print_r(student_detail); 
      echo "</pre>"; 
    }
}

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Student extends CI_Controller {

function __construct()

{

parent::__construct();

}

public function index()

{

$student_detail = get_all_student_rows();

echo "<pre>";

print_r(student_detail);

echo "</pre>";

}

View Example

<?php
     $student_detail = get_all_student_rows(); 
     echo "<pre>"; 
     print_r(student_detail); 
     echo "</pre>";
?>

<?php

$student_detail = get_all_student_rows();

echo "<pre>";

print_r(student_detail);

echo "</pre>";
