how to show an array using Ajax and Symfony - arrays

Question

i am trying to show a consult which have an array with arrays in symfony using Ajax and json, this is my ajax's script :
<script>
var boton=document.getElementById("form_Boton");
function ajax() {
var nombre=$('#form_nombre').val();
$.ajax({
type: 'POST',
url: "{{ path('buscar_porCriterio') }}",
data: ({nombre: nombre}),
dataType:"json",
beforeSend:function () {
alert("enviará a: "+nombre);
},
success:function (resp) {
if(resp!=""){
$('#resultados').html(resp["nombre"]+" "+resp["apellido"]+" "+resp["residencia"]);
}
if(resp==""){
alert("NO SE ENCONTRO NADA");
}
}
})
}
boton.addEventListener("click",ajax);
</script>
And this is my controller:
public function PorCriterioAction(Request $request){
if(!$request->isXmlHttpRequest())
{
throw new Exception("Error, NO ES AJAX");
}
$nombre=$request->request->get('nombre');
$em=$this->getDoctrine()->getManager();
$encontradas=$em->getRepository('FormulariosBundle:persona')->findBynombre($nombre);
if ($encontradas == null) {
$response = new Response("VACIO " . $nombre . " Sorry");
return $response;
}
else{
$persona_encontrada = (array("id" => $encontradas->getId(),
"nombre" => $encontradas->getNombre(),
"apellido" => $encontradas->getApellido(),
"residencia" => $encontradas->getResidencia()
));
$response= new JsonResponse($persona_encontrada);
return $response;}}
what i need is get all data from my DB whose name be $nombre, and show every data in my div 'resultados'. but. when i realize my search, symfony show me this exception:
Exception
my question is: How can i do to pass every data of that consult to my div 'resultados'?
as you see, i want to show such consult in a div whose id is "resultados" but does not work, can you help me please? i am a beginner in symfony and i have to make this University Proyect and finish my study, thanks for your answer
EDIT # 2
this is the change to my controller:
public function PorCriterioAction(Request $request){
if(!$request->isXmlHttpRequest())
{
throw new Exception("Error, NO ES AJAX");
}
$nombre=$request->request->get('nombre');
$em=$this->getDoctrine()->getManager();
$encontradas=$em->getRepository('FormulariosBundle:persona')->findBynombre($nombre);
if ($encontradas == null) {
$response = new Response("VACIO " . $nombre . " Sorry");
return $response;
}
else{
foreach ($encontradas as $Item){
$persona_encontrada = (array("id" => $Item->getId(),
"nombre" => $Item->getNombre(),
"apellido" => $Item->getApellido(),
"residencia" => $Item->getResidencia()
));
array_push($persona_encontrada,$Item);
}
$response= new JsonResponse($persona_encontrada);
return $response;
}
}
is this what you need? responseText

Answer 1

I believe $encontradas is a results set so try this:
foreach( $encontradas as $item){
$persona_encontrada = (array(
"id" => $item->getId(),
"nombre" => $item->getNombre(),
"apellido" => $item->getApellido(),
"residencia" => $item->getResidencia()
));
}
Let us know the result.
EDIT #2
I see the problem. Since it iterates through the array, you want $persona_encontrada to be an array and then use the PHP array_push to add array elements to it. You could do it like so:
$persona_encontrada = array();
foreach( $encontradas as $item){
$element = array(
"id" => $item->getId(),
"nombre" => $item->getNombre(),
"apellido" => $item->getApellido(),
"residencia" => $item->getResidencia()
);
array_push( $persona_encontrada, $element);
}
By the way, although this will work for you, it might not be the best way to do something like this. But it will work.
