I can't call an arrays passed from the php json encode. I would concatenate 2 select state-contry-city. How can I do this??
This is the code:
I have 2 selects. I send the first value to an action:
php action into my controller:
public function regioniProvinceComuniAction(){
$response = $this->getResponse();
$request = $this->getRequest();
if ($request-> isPost()){
$post_data = $request->getPost();
$regione = (int)$post_data['regione'];
$province = (int)$post_data['province'];
}
if(isset($regione)){
$prov = $this->getProvincia($regione);
}
if(isset($province)){
$com = $this->getComuni($province);
}
$response->setContent(\Zend\Json\Json::encode(array('prov' => $prov, 'com' => $com)));
return $response;
}
This is my js file:
$("select#Regione").change(function () {
var regione = $("select#Regione option:selected").attr('value');
$.ajax({
type: 'POST',
url: '/zf-tutorial/public/regioni-province-comuni',
datatype: 'json',
data: { regione: regione },
success: function (data) {
alert (data);
}
});
});
An example of the alert function is like this:
{"prov":[{"id":"10","nome":"Genova"},{"id":"8","nome":"Imperia"},{"id":"11","nome":"La Spezia"},{"id":"9","nome":"Savona"}],"com":[]}
I tried to populate my second select via data.post like this, but the values are "undefined":
success: function (data) {
$('select#Provincia option').each(function(){$(this).remove()});
for(var i=0; i<data.length; i++){
$("select#Provincia").append('<option value="' + data[i].prov.id + '">' + data[i].prov.nome + '</option>');
}
i tried to do
for (var i = 0; i < data.prov.length; i++) {
$("select#Provincia").append('<option value="' + data.prov[i].id + '">' + data.prov[i].nome + '</option>');
}
if i set manually the var data, works fine, but with the response data doesn't work. i tried to do:
var prov = data.prov;
$("div#id").html(prov);
but it doesn't work. works only like this:
$("div#id").html(data);
and the output is the same
{"prov":[{"id":"10","nome":"Genova"},{"id":"8","nome":"Imperia"},{"id":"11","nome":"La Spezia"},{"id":"9","nome":"Savona"}],"com":[]}
