php refreshing only data in page












-1















i'm a php nearby. I have a problem with my form. I connect the controller with db and extract a question and his three answers. If i click on one of this, the system return the second question, under the first question. If i click on one of the seconds answers, the system return the thirth question overwrite the second question.
I would like that second question (and its answers) overwrite the first (and its answers). How i can?

In your view:



...
<?php
while ($rispost = pg_fetch_object($reslt2)) {
print "<td><button type='submit' name='btnScelta'
value='$rispost->id_domanda_successiva'>$rispost->risposta</button>
</td>";
}

?>


you are setting only one value in each button. which is available as $_POST['btnScelta'] and that is used to render your last question.



Edit previous contents removed because they are not relevant to the question.



To render two questions pass two ids as the button value.




To remove the first question remove the two lines from your index.php




1) index.php



<?php 
error_reporting(E_ERROR | E_PARSE);
require_once 'controllers/controller.php';
$controllers = new Controller();
/* remove the following two lines the first question wont be rendered.*/
//$controllers->cercaDomanda(1);
//$controllers->cercaRisposta(1);
$controllers->cercaNuovoId(/*$id*/);
?>


Now make controller process two question display.



class Controller {
public function cercaNuovoId(/*$id*/){
// include 'views/basicView.php';
$reslt3 = $this->model->getIdNext();
// render previous question only if a value exists.
if ($result3) {
list($current, $previous) = explode(',', $result3);
$this->cercaDomanda($previous);
$this->cercaRisposta($previous);
}
// show the first question on first visit.
if (empty($current)){
$current = 1;
}
$reslt4 = $this->cercaDomanda($current);
$reslt5 = $this->cercaRisposta($current);
}
}


Now in the view make modification for button to have two values seperated by comma. current question id is available as $id from Controller::cercaRisposta()



<?php 
while ($rispost = pg_fetch_object($reslt2)) {
print "<td><button type='submit' name='btnScelta'
value='{$rispost->id_domanda_successiva},{id}'>$rispost->risposta</button>
</td>";
}
?>
</form>


you can also pass the previous question id by changing form's action property with a query like index.php?previous=$id.

?>


you are setting only one value in each button. which is available as $_POST['btnScelta'] and that is used to render your last question.

//$controllers->cercaDomanda(1);
//$controllers->cercaRisposta(1);
$controllers->cercaNuovoId(/*$id*/);
?>


Now make controller process two question display.



class Controller {
public function cercaNuovoId(/*$id*/){
// include 'views/basicView.php';
$reslt3 = $this->model->getIdNext();
// render previous question only if a value exists.
if ($result3) {

}

</form>


you can also pass the previous question id by changing form's action property with a query like index.php?previous=$id.

In your view:



...
<?php
while ($rispost = pg_fetch_object($reslt2)) {
print "<td><button type='submit' name='btnScelta'
value='$rispost->id_domanda_successiva'>$rispost->risposta</button>
</td>";
}

?>


you are setting only one value in each button. which is available as $_POST['btnScelta'] and that is used to render your last question.



Edit previous contents removed because they are not relevant to the question.



To render two questions pass two ids as the button value.




To remove the first question remove the two lines from your index.php




1) index.php



<?php 
error_reporting(E_ERROR | E_PARSE);
require_once 'controllers/controller.php';
$controllers = new Controller();
/* remove the following two lines the first question wont be rendered.*/
//$controllers->cercaDomanda(1);
//$controllers->cercaRisposta(1);
$controllers->cercaNuovoId(/*$id*/);
?>


Now make controller process two question display.



class Controller {
public function cercaNuovoId(/*$id*/){
// include 'views/basicView.php';
$reslt3 = $this->model->getIdNext();
// render previous question only if a value exists.
if ($result3) {
list($current, $previous) = explode(',', $result3);
$this->cercaDomanda($previous);
$this->cercaRisposta($previous);
}
// show the first question on first visit.
if (empty($current)){
$current = 1;
}
$reslt4 = $this->cercaDomanda($current);
$reslt5 = $this->cercaRisposta($current);
}
}


Now in the view make modification for button to have two values seperated by comma. current question id is available as $id from Controller::cercaRisposta()



<?php 
while ($rispost = pg_fetch_object($reslt2)) {
print "<td><button type='submit' name='btnScelta'
value='{$rispost->id_domanda_successiva},{id}'>$rispost->risposta</button>
</td>";
}
?>
</form>


you can also pass the previous question id by changing form's action property with a query like index.php?previous=$id.
