如何将JS数组传递给PHP数组 [英] How to pass a JS array to PHP array

问题描述

我想将JS数组转换为PHP数组。我试图将值发送到PHP页面：

  var  seatsReserved = []; 
 
  function  reserve（seat）{
 seat.setAttribute（  class，  reserved） ; 
  var  hasClass = seat.classList.contains（' 保留'）; 
  if （hasClass）{
 seatsReserved.push（ parseInt （seat.innerHTML） ））; 
 
 $ .post（'  ../ index.php'，{ '  seatsReserved'： JSON  .stringify（ seatReserved）}）; 
  console  .log（seatsReserved.sort（ function （a，b）{返回 ab}））; 
} 
} 

然而，当我跑步时

  $ seatsReserved  = json_decode（$ _ POST ['' < span class =code-string> seatsReserved']）; 

我收到此错误：

注意：未定义索引：seatsReserved 

如何正确地将数组传递给PHP ？

解决方案

.post（' ../ index .php'，{' seatsReserved'： JSON .stringify（seatsReserved）}）;
console .log（seatsReserved.sort（ function （a，b）{返回 ab}））;
}
}

然而，当我跑步时

seatsReserved = json_decode（

< blockquote> _POST [' seatsReserved']）;

我收到此错误：

注意：未定义索引：seatsReserved 

如何才能正确地将数组传递给PHP？

I would like to convert a JS array to a PHP array. I tried to send the value to the PHP page:

var seatsReserved = [];

function reserve(seat){
seat.setAttribute("class","reserved");
var hasClass = seat.classList.contains('reserved');
if (hasClass) {
seatsReserved.push(parseInt(seat.innerHTML));

$.post('../index.php', { 'seatsReserved': JSON.stringify(seatsReserved) });
console.log(seatsReserved.sort(function(a, b){return a-b}));
}
}

However, when I run

$seatsReserved = json_decode($_POST['seatsReserved']);

I get this error:

Notice: Undefined index: seatsReserved

How can I correctly pass the array to PHP?

解决方案

.post('../index.php', { 'seatsReserved': JSON.stringify(seatsReserved) }); console.log(seatsReserved.sort(function(a, b){return a-b})); } }

However, when I run

seatsReserved = json_decode(

_POST['seatsReserved']);

I get this error:

Notice: Undefined index: seatsReserved

How can I correctly pass the array to PHP?
