Confession:
I read many similar questions on this platform, but nothing seems closely aligned to my situation. Most of the questions seem to originate from binding params in prepared statements or execute statement.
In my case, the website runs smooth on a local server(Apache2). However, it throws the error below when published on live server.
Fatal error: Uncaught Error: Call to a member function signin() on boolean in /storage/ssd5/815/17670815/app/controllers/signin.php:16 Stack trace: #0 /storage/ssd5/815/17670815/app/core/app.php(33): Signin->index() #1 /storage/ssd5/815/17670815/public_html/index.php(4): App->__construct() #2 {main} thrown in /storage/ssd5/815/17670815/app/controllers/signin.php on line 16
Context I'm using MVC (OOP) in PHP and here the relevant parts mentioned in the error. I hope this is not too much.
In the main index page, the line referred in the error is a core class(App) instantiation
<?php
session_start();
require_once '../app/initializer.php';
$app = new App(); //this is the line 4 mentioned in the error
In Signin controller class the line referred in the error is indicated below
<?php
class Signin extends Controller{
function index(){
//you can do this if passing data to view
$data["Page_title"] = "Signin";
if($_SERVER['REQUEST_METHOD'] == "POST"){
// this is a debuggin code
//echo "I am signin controller <br />";
// show($_POST);
$user = $this->loadModel("User");
$user->signin($_POST); //this the line referred in the error
}
$this->view("zac/signin",$data);
}
}
In class APP the line is a callback - check below
<?php
class App {
private $controller = "home";
private $method = "index";
private $params = [];
public function __construct()
{
$url = $this->splitURL();
if(file_exists("../app/controllers/".strtolower($url[0]).".php")){
$this->controller = strtolower($url[0]);
//unset the array position
unset($url[0]);
}
require "../app/controllers/".$this->controller.".php";
// echo file_get_contents('http://smart-ecom.000webhostapp.com/app/controllers/'.$this->controller.".php");
//Create instance of whatever controller class is passed(if it exists, otherwise the home controller)
$this->controller = new $this->controller;
if(isset($url[1])){
if(method_exists($this->controller, $url[1])){
$this->method =$url[1];
unset($url[1]);
}
}
$this->params = array_values($url);
call_user_func_array([$this->controller, $this->method],$this->params); //this is line 33
}
/**
* splitURL gets url from browser and processes against the conroller classes and their methods
* @return array
*/
private function splitURL(){
//check if the the GET is set otherwise set the url to defualt class home
$url = isset($_GET['url']) ? $_GET['url'] :"home";
// return explode("/",filter_var(trim($_GET['url'],"/"), FILTER_SANITIZE_URL));
return explode("/",filter_var(trim($url,"/"), FILTER_SANITIZE_URL));
}
}
?>
The Database class's read function is as follows. This method isn't directly referred in the error message
public function read($query, $data = []){
$stmt = self::$conn->prepare($query);
$result = $stmt->execute($data);
if($result){
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
if(is_array($data) && count($data) > 0){
return $data;
}
}
return false;
}
As I mentioned earlier, this error fires on a live server but the website runs smooth in dev environment with PHP 7.4, Apache2, MySQL 8 Windows 10.
Your help is match appreciated in advance.
