hi everyone

I have this site i want to make changes to the contact form. Right now it sends the info to a database and posts in the admin area. I have this file controller.php that has a section with a funtion function Cuenta_Contactos that i think passes the info. Is there a way to add an email address there so it sends the message to that email account? Thanks ive attached the file .

I'm using this struture to run my application, everything works fine, but i don't like how the controllers are called. If i load the model in construct it will work great again, but i think that is unnecessary.

You can see two pieces of code about controller "Post.php", the last one, works great.

If i try this: (Posts.php)

    namespace app\controllers;
    
    use app\libraries\Controller;
    use app\models\User;
    
    class Posts extends Controller {    
        public function index():void {
            //Get posts
            $user = new User();
            $posts = $user->posts();
            $data = [
                'posts' => $posts
            ];
    
            $this->view('posts/index', $data);
        }
    }

I will get an error:

I'm very new to MVC and I'm trying to figure out how to transition my code and I'm not sure where to place things.  It easy to want to just put everything in the view, but I know that doesn't make sense.

Can you please guide me on how I should transition the rest of my code for my header? I'm currently using codeigniter.

Current View
Code: [Select]
<?php

$page = substr(end(explode(DIRECTORY_SEPARATOR, $_SERVER['PHP_SELF'])), 0, -4);

$title = (array_key_exists($page, $page_names) !== false) ? $page_names[$page]: '';

if (array_key_exists($page, $page_names) !== false)
{
$title .= " | Jason Biondo";
}

$banner_imgs  = array('contact.jpg', 'about.jpg', 'tools.jpg', 'portfolio.jpg', 'articles.jpg');
$nav_names  = array('Contact', 'About', 'Tools', 'Portfolio', 'Articles');
$gutter_values  = array('307', '230', '161', '84', '0');

Hi 

I will try and explain this as best I can, as I am not sure if the "include" is causing the problem.

What I am trying to achieve is count the total number of vehicles in the "vehicles" db table and pass it to views (I have recently moved over to MVC so still learning so please be kind and keep it simple for me please)

I have a folder in views called "vehicletracker" , within this folder I have 2 files "index.php" and "widget.php".........The "widget.php" file  is an "include" within "index php".

The problem I am having is passing data from the controller to the view, I keep getting an "Undefined index: total" error and wonder if someone can help and show me where I am going wrong.

This is my Model

 

 <?php

 class Widget {
    private $db;
    
    public function __construct(){
      $this->db = new Database;
    }
      
      public function countVehicles(){
      $this->db->query("SELECT * FROM vehicles");
      return $this->db->rowCount();
    }  
      
      
  }

This is my controller

 

<?php
  class Widgets extends Controller{
    public function __construct(){
     $this->widgetModel = $this->model('Widget');
        
    
   public function widget (){
       $data['total'] = $this->widgetModel->countVehicles();
       $this->view('vehicletracker/widget', $data);
   }
        
        
}

And my view

 

<h2 class="text-white"><?php echo $data['total']; ?></h2>

 

Thanks in advance for any help you can give

I am currently building my own MVC Framework and I have run into an issue that I can't solve when attempting to use 2 methods from a single model. I know that this isn't an issue with the queries or information being return. I am unsure of the proper way that I can call 2 methods when checking to see if a user is logged in... The issue that I face is both methods are calling the DB and it throws a PDO error which I don't know how to get around the issue.. Any guidance would be nice as I have been banging my head over this issue. Thank you!
