Question

在控制台日志中，我看到使用json_encode（）返回以下数据;检查此附加图像。

enter image description here

当我点击发送按钮时，它正在使用

调用 submit.php 页面显示数据

<?php
  print_r($_REQUEST);
?>

它告诉我

Array ( [data] => Shibbir, )

但是我希望得到cdid和label键值，因为您可以看到我的附加图片，它在控制台日志中显示了cdid和标签值。

search.php页面

<?php
require_once("../frontend/config.php");
$term = $_GET['term'];
$sql = mysqli_query($link, "SELECT cdid, family_name, given_name FROM contact_details WHERE family_name LIKE '%$term%' ");
 $return_arr = array();
 while ($row = mysqli_fetch_array($sql, MYSQL_ASSOC)) {
    $row_array['cdid'] = $row['cdid'];
    $row_array['label'] = $row['family_name'];


    array_push($return_arr, $row_array);
}
echo json_encode($return_arr);    
?>

使用另一个php页面获取所有JSON返回数据
