如何在PHP中接收ajax發送的JSON數據

Question

我有想要發送到后端的數據，它看起來像

function lihat(){
    let id = "12345678";
    let profile = [{name:"dave", department : "Engginering"},
                   {name:"Tedd", department : "Engginering"}]
    $.ajax({
        type:'POST',
        url:'pages/dashboard/dashboard_be.php'
        data:{
            cekload  : true,
            keys     : id,
            dataList : profile 
        },
        success:function(data){
            console.log(data);
        }
   })

問題，我怎樣才能在 php 腳本中接收 ajax 發送的所有數據，這是我試過的

    $id      = $_POST['keys'];
    $cekload = $_POST['cekload'];
    $data    = json_decode($_POST['dataList'];);

   //I wanna parsing the dataList object and then loop it, how to make it ?

謝謝，之前

如果您嘗試發送/接收 javascript 對象，則需要先將 object 轉換為字符串，然后再將其發送並解碼回 php（可能是數組），然后再讀取。

<script>
    let id = "12345678";
    let profile = [{name:"dave", department : "Engginering"},
                   {name:"Tedd", department : "Engginering"}]
    $.ajax({
        type:'POST',
        url:'pages/dashboard/dashboard_be.php',
        data:{
            cekload  : true,
            keys     : id,
            dataList : JSON.stringify(profile) 
        },
        success:function(data){
            console.log(data);
        }
   });
</script>

PHP 代碼：

<?php 
$id = $_POST['keys'];
$cekload = $_POST['cekload'];
$data = json_decode($_POST['dataList'], true);

echo $id;
echo $cekload;
print_r($data);
?>
