I have this class and function

class Controller {

  public function vazio($verfica) {
      if (empty($verfica)) {
          return 'Vazio';
      } else {
          return 'Ok';
      }
  }

}

I call that function within the append it is necessary to concatenate the variable within the function

divposts.append("<?php echo $ctlr->vazio("+val.valor+")?>");
php javascript

  • There is no way to do this because PHP is processed on the server and JS in the browser after PHP has done its part.

In your case, as your function lies within your controller responsible for its requests and you’re using the architecture MVC, the correct would be through the javascript you call that your function controller.

For example:

Your Javascript

$.ajax({
  url: window.location.origin + '/sua-rota-apontada-para-controller',
  type: 'GET' // método http da sua rota
  dataType: 'application/json',
  success: function(data){
    divposts.append('<span>' + data + '</span>');
  },
  erro: function(err){
    console.log(err);  
  }
});
