PHP - Moved: Model In Controller

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.

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!

Wrong Code

Hi; I have succesfully managed to route all the traffic to the file controller.php using this command line of .htaccess :

RewriteEngine On
RewriteRule (.*) /var/www/html/site/controller.php [L,QSA]

Now how to tell the controller.php to process the url that was passed. For example i have tried that:   controller.php :

<?php
    include( $_SERVER["REQUEST_URI"] );
?>

but the controller.php didn't do anything i keep getting a blank page when i browse any webpage such as site/index.php so how to tell controller.php to echo the content of the request ? because the user shouldn't notice any change as if there is no controller.php.   Thank you.

I have a list of checkboxes, like e.g each checkbox has a value as ResumeID,
now question is/are;

1) how to get the values of the checkboxes using jQuery ?
2) when I got the values of the checkboxes using jQuery, how to pass those values to a PHP Controller action ? 

I am developing a new promising service (media-industry) in the Los Angeles area. Contact me if interested.  Leroy.

Hi,

I have a cakePHP program that works and displays data from a database table.
The part I dont understand and I couldnt find anything on the cakephp blog as yet was the model was left blank?

q1) The model is left blank but still works so what is the default behaviour here for the model? It doesnt seem to be needed to do anything i?.

q2)I am selecting all the data from 1 table but how do I add  a sql statement to select part of the table or a join of 2 tables? the find 'all' seems to just do that only in finding all data from a table.   <?php
class Post extends AppModel
{
/*var $name='User';*/
}
?>


<?php
class PostsController extends AppController
{
public $helpers=array('Html','Form');

public function index()
{
$this->set('posts',$this->Post->find('all'));
}

public function home()
{
$this->set('posts',$this->Post->find('all'));
}
}
?>

view
///
..
<?php foreach ($posts as $item):
echo '<tr><td>'. $item['Post']['id']. '</td>';
echo '<td>'. $item['Post']['title'].'</td>';
echo '<td>'. $item['Post']['body'].'</td>';

echo '<td>'. $item['Post']['created'] .'</td>';
echo '</tr>';
endforeach;
unset($item);
?>

Hello

I'm developing a Model-View-Controller framework for my personal learning curve. I've created an active record class and I've got stuck when using variables in a where clause. My problem is this:

When, in a where statement, you want to find the Users with the first name Mike, you might write
SELECT Firstname, Surname FROM Users WHERE Firstname = 'Mike'

Where Mike is enclosed with quotation marks. When you're comparing entities quotation marks shouldn't be used.
For example,

SELECT Firstname, Surname, OrderTitle FROM Users, Orders WHERE Firstname = 'Mike' AND Users.Firstname = Orders.Firstname

So when using variables in my where statements, like

$Name = Mike
$this->Where(Firstname',$Name);
$this->Where('Users.Firstname','Orders.Firstname');

How do I differentiate, in my function Where() when to enclose the string with quotation marks, i.e when it is a (Table.Entity) rather than a constant.

Thank you

Can a person instantiate a model? If so how do you do it. I already know how to instantiate a class

thank you

Hey all,   I am making a application that requires a user to login in. I have a user model, which does such things as finds, registers, logins in, updates etc a user. It also grabs all of a users data from a database, such as their username, email address etc and checks whether or not a user is logged in.   The problem I face is this. I want to control what content a user can see depending on if they are logged in or not. In addition to this, I want to output the users data, such as their username, in other parts of the website – such as the header and footer. There is no real easy way of doing this, and requires the user model to be instantiated on every page. My question is should this class be a model or just a core library class?

Hi Everyone.
I am in need of assistance,
I need a form that i will use on a model agency site i am making, the form i have only has the option to upload one image and records name, age etc... What i need is a form that will upload multiple images, 2 will do but if i had a option to add more that would be great, and a pdf resume, does anyone have a similar form i can have a look at that does this, any help be awesome, i am already over the deadline.

Hi all, I was just wondering is this possible what I'm trying to do? Models can only store one object at a time... I'm trying to access multiple objects via one model...

<?php

	class users extends Model {
		
		protected $username;
		protected $firstname;
		protected $secondname;
		protected $age;
		// There will be more here...
		
		public function __construct($id = NULL) {
			
			if($id != NULL) {
				
				$this->username = $sql->getUsername($id);
				$this->firstname = $sql->getFirstname($id);
				$this->secondname = $sql->getSecondname($id);
				$this->age = $sql->getAge($id);
				
			}
			
		}
		
		public function numOfUsers() {
			
			$num = $sql->countAllUsers($query);
			
			return $num;
			
		}
		
		public function getUsername() {
			
			return $this->username;
			
		}
		
		public function getFirstname() {
			
			return $this->firstname;
			
		}
		
		public function getSecondname() {
			
			return $this->secondname;
			
		}
		
		public function getAge() {
			
			return $this->age;
			
		}
		
	};
	
	class UsersView extends View {
		
		$users = new users();
		
		for($i = 0; $i < $users->numOfUsers(); $i++) {
		
			$user = new users($i);
			echo "Username: {$user->getUsername()}";
			echo "Username: {$user->getFirstname()}";
			echo "Username: {$user->getSecondname()}";
			echo "Username: {$user->getAge()}";
			
		}
		
	};
