I'm going to enjoy that I've got my hand in the dough to explain to you.
When you have an array in php
in this format (executing a var_dump($array)
on the server):
object (stdClass) # 6394 (59) {["id_customer"] = > string (1) "1"
["fk_customer_civilstatus"] = > string (1) "1" ["hashed_id"] = > string (6)
"xxxxxx" ["name"] = > string (17) "Marcelo Bonifazio" ["cpf"] = > NULL
["phone"] = > string (15) "" ["email"] = > string (28)
"[email protected]" ["password"] = > string (60)
"" ["gender"] = > string (1) "M" ["birthdate"] = > string (10)
"1991-12-04" ["id_google"] = > NULL ["id_facebook"] = > NULL
["avatar_url"] = > NULL ["changekey"] = > NULL ["last_access"] = >
string (19) "2017-01-25 02:45:17" ["created_at"] = > NULL
["updated_at"] = > NULL ["idusuario"] = > string (6) "xxxxxx"
["id_address"] = > string (1) "1" ["postal_code"] = > string (9) "00000-000"
["country"] = > string (6) "Brazil" ["street"] = > string (25) "" ["state"] = > string (2) "SP" ["city"] = > string (10) "Are
"" "" "" ["Number"] => string (2) "99" ["district"] => string (12) "" "[" complement "] => string (0)" "[" id_creditcard "] = > NULL
["creditcard"] = > NULL ["total_price"] = > string (4) "1490"
["id_coupons"] = > NULL ["coupon_name"] = > NULL ["coupon_code"] = > NULL
["discount"] = > NULL ["duration_months"] = > NULL ["start_date"] = > NULL
["end_date"] = > NULL ["id_sales_order_item"] = > string (1) "1"
["fk_sales_order"] = > string (1) "1" ["fk_product"] = > string (2) "22"
["contract_sl_id"] = > NULL ["fk_sales_order_item_status"] = > string (1)
"1" ["fk_sales_order_item_cancellation"] = > NULL ["fk_shipping"] = > NULL
["original_unit_price"] = > string (4) "1490" ["final_unit_price"] = >
string (4) "1490" ["trial_start"] = > string (19) "0000-00-00 00:00:00"
["trial_end"] = > string (19) "0000-00-00 00:00:00" ["active_from"] = >
NULL ["active_until"] = > NULL ["id_subscription_status_type"] = >
string (1) "3" ["status"] = > string (9) "frozen"
["id_payment_method"] = > NULL ["method"] = > NULL
["id_sales_order_item_cancellation"] = > NULL ["request_date"] = > NULL
["cancellation_date"] = > NULL ["reason"] = > NULL}
When you change the return format by running: json_encode($array)
you get:
{"id_customer": "1", "fk_customer_civilstatus": "1", "hashed_id": "xxxxxx", "name": "Marcelo
Bonifazio "," cpf ": null," phone ":" "," email ":" [email protected] "," password ":" "," gender ":" M "," birthdate " 12-04 "," id_google ": null," id_facebook ": null," avatar_url ": null," changekey ": null," last_access ":" 2017-01-25
"Updated_at": null, "userid": "7Z2PZ6", "id_address": "1", "postal_code": "00000-000", "country": " Brazil "," street ":" "," state ":" SP "," city ":" S \ u00e3o
Null, "total_price": "1490", "id_coupons": null, "creditcard": null, "total_price": " , "coupon_name": null, "coupon_code": null, "discount": null, "duration_months": null, "start_date": null, "end_date": null, "id_sales_order_item": "1", "fk_sales_order" 1 "," fk_product ":" 22 "," contract_sl_id ": null," fk_sales_order_item_status ":" 1 "," fk_sales_order_item_cancellation ": null," fk_shipping ": null," original_unit_price ":" 1490 "," final_unit_price " 1490 "," trial_start ":" 0000-00-00
00:00:00 "," trial_end ":" 0000-00-00
"Active_until": null, "id_subscription_status_type": "3", "status": "frozen", "id_payment_method": null, "method": null, "id_sales_order_item_cancellation" : null, "request_date": null, "cancellation_date": null, "reason": null}
Make sure this second format is a json
valid ( online tool that checks if a json is valid , throw the above string and test ).
Now in the part of client-side
that requests this query you can put together a script that works with ajax
like this:
jQuery.ajax({
url: "/api/user/",
type: "POST",
data: data,
success: function(returnjson) {
alert(returnjson.id_customer);
},
error: function(returnjson) {
if (returnjson.status == 500) {
alert("Erro interno do servidor, tente novamente ou entre em contato com o suporte técnico.");
} else {
alert(returnjson.responseJSON.msg);
}
}
});
Within alert(returnjson.id_customer);
you will have printed the value that returned from your json
.
Remember that it's also important to set the correct header
on the server: header('Content-Type: application/json');
In your case, you can work on your page php
as follows:
header('Content-Type: application/json');
$equipe1 = $_POST['equipe1'];//Pega o Nome da equipe
$equipe2 = $_POST ['equipe2'];//Pega o Nome da equipe
$dificuldade = $_POST ['dificuldade'];//Define a dificuldade das perguntas que seram selecionadas
$rodada = $_POST ['rodada'];//Número de perguntas que serão retornadas
switch ($dificuldade) {
case '1':
$dificuldade = "Facil";
break;
case '2':
$dificuldade = "Medio";
break;
case '3':
$dificuldade = "Dificil";
break;
}
switch ($rodada) {
case '1':
$rodada = "10";
break;
case '2':
$rodada = "15";
break;
case '3':
$rodada = "20";
break;
}
try{
$conexao = new PDO ("mysql:host=localhost; dbname=teocratico; charset=utf8","root","");
} catch (PDOException $erro){
echo $erro->getmessage();
//header($_SERVER['SERVER_PROTOCOL'] . ' 500 Internal Server Error', true, 500);
}
$consulta = $conexao->query ("SELECT id_pergunta, pergunta, resposta, desafio FROM perguntas
where dificuldade ='$dificuldade' ORDER BY rand() LIMIT $rodada ");
// Mostrando a Consulta
$db_data = $consulta->fetch(PDO::FETCH_ASSOC);
die(json_encode($db_data));
