What is a Smarty Template?

Smarty is a template engine for PHP which helps to keep code cleaner.
Template files are saved with .tpl extension.
Template files contain simple html tags and some php code.

Example :

How to display a message on smarty template?

    function __construct(Controller $ctl){

    }

  

    function page(Controller $ctl){

       $ctl->assign("message","Hello world!!!");

       $ctl->show_multi_dialog("helloworld", "message.tpl", "Hello world!!!",1000,true,true);

    }



}

How to use an array with smarty template?

You can use arrays to display,

1) Radio button options
2) Dropdown menu options

In the template file where you want to use the array,

1)Add the following code to display radio buttons

{html_radios name="fruits" options=$fruits}

2)Add the following code to display dropdown menu options

{html_options name="fruits" options=$fruits}

In the helloworld.php add the following code.

class helloworld {

    private $fruits;

        

    function __construct(Controller $ctl){

	$this->fruits= [0=>"apple", 1=>"orange"];

        $ctl->assign("fruits",$this->fruits);

    }

}

Now you can see the dropdown menu and radio buttons when you run the program.
