I don't know if the title above is an correct title about my question.
Is there a way to declare a variable which we can access it from anywhere in view without need to redefine it again in each function in controller?
for example in controller file Students.php contains many function that handle the views, take a look below :
public function __construct() {
parent::__construct();
$data['count_student'] = $this->m_data->allStudent(); // count all students
}
public function index() {
$data['content'] = 'view-students';
$this->load->view('frontend/header' , $data);
}
public function showDetails() {
$data['content'] = 'view-detail-students';
$this->load->view('frontend/header' , $data);
}
I expected we can access $count_student in both view-students.php and view-detail-student.php without to define $data['count_student'] = $this->m_data->allStudent(); on each function that handle the view.
Is there possible ways to do that?
I noticed that you can access variables in views without passing them if you declare them in the controller with $this->. Probably because they default to public visibility.
public function __construct() {
parent::__construct();
// $data['count_student'] = $this->m_data->allStudent(); // count all students
//
$this->count_all_the_students = $this->m_data->allStudents();
}
public function index() {
$data['content'] = 'view-students';
$this->load->view('frontend/header' , $data);
}
And then in the view you can use $this->count_all_the_students without putting it in the $data array.
<?php defined('BASEPATH') OR exit('No direct script access allowed'); ?>
<?php
echo 'I have misled ' . $this->count_all_the_students . ' students with my MVC breaking suggestions.';
