The letter “V” in the MVC is for Views. Views are responsible for sending output to user based on request. View Classes is a powerful way to speed up the development process.

View Templates

The View Templates file of CakePHP has default extension .ctp (CakePHP Template). These templates get data from controller and then render the output so that it can be displayed properly to the user. We can use variables, various control structures in template.
Template files are stored in src/Template/, in a directory named after the controller that uses the files, and named after the action it corresponds to. For example, the View file for the Products controller’s “view()” action, would normally be found in src/Template/Products/view.ctp.
In short, the name of the controller (ProductsController) is same as the name of the folder (Products) but without the word Controller and name of action/method (view()) of the controller (ProductsController) is same as the name of the View file(view.ctp).

View Variables

View variables are variables which get the value from controller. We can use as many variables in view templates as we want. We can use the set() method to pass values to variables in views. These set variables will be available in both the view and the layout your action renders. The following is the syntax of the set() method.

Syntax

Cake\View\View::set(string $var, mixed $value)
This method takes two arguments − the name of the variable and its value.

Example

Make Changes in the config/routes.php file as shown in the following program.
config/routes.php
<?php
   use Cake\Core\Plugin;
   use Cake\Routing\RouteBuilder;
   use Cake\Routing\Router;

   Router::defaultRouteClass('DashedRoute');
   Router::scope('/', function (RouteBuilder $routes) {
      $routes->connect('template',['controller'=>'Products','action'=>'view']);
      $routes->fallbacks('DashedRoute');
   });
   Plugin::routes();
Create a ProductsController.php file at src/Controller/ProductsController.php. Copy the following code in the controller file.
src/Controller/ProductsController.php
<?php
   namespace App\Controller;
   use App\Controller\AppController;
   
   class ProductsController extends AppController{
      public function view(){
         $this->set('Product_Name','XYZ');
      }
   }
?>
Create a directory Products at src/Template and under that folder create a View file called view.ctp. Copy the following code in that file.
src/Template/Products/view.ctp
Value of variable is: <?php echo $Product_Name; ?>
Execute the above example by visiting the following URL.
http://localhost:85/CakePHP/template

Output

The above URL will produce the following output.

The table creation command requires: Name of the table Names of fields Definitions for each field Syntax: Here is generic SQL syntax to create a MySQL table: CREATE TABLE table_name ( column_name column_type ); Now, we will create following table in  TUTORIALS  database. tutorials_tbl ( tutorial_id INT NOT NULL AUTO_INCREMENT , tutorial_title VARCHAR ( 100 ) NOT NULL , tutorial_author VARCHAR ( 40 ) NOT NULL , submission_date DATE , PRIMARY KEY ( tutorial_id ) ); Here few items need explanation: Field Attribute  NOT NULL  is being used because we do not want this field to be NULL. So if user will try to create a record with NULL value, then MySQL will raise an error. Field Attribute  AUTO_INCREMENT  tells MySQL to go ahead and add the next available number to the id field. Keyword  PRIMARY KEY  is used to define a column as primary key. You can use multiple columns separated by comma to define...
