使用锚定标记将数据发送到另一个文件中的php脚本，同时打开引导模式

我有如下html：

<a href="./libs/php/edit.php?edit=<?php echo $row['lastName']; ?>" class="btn btn-info">Edit</a>

处理数据的php脚本：

<?php

 ini_set('display_errors', 'On');
 error_reporting(E_ALL);
 $executionStartTime = microtime(true);

 include("config.php");
 $conn = new mysqli($cd_host, $cd_user, $cd_password, $cd_dbname, $cd_port, $cd_socket) or 
 die(mysqli_error($conn));


 $department = " ";
 $location = " ";
 $update = false;

 if (mysqli_connect_errno()) {

$output['status']['code'] = "300";
$output['status']['name'] = "failure";
$output['status']['description'] = "database unavailable";
$output['status']['returnedIn'] = (microtime(true) - $executionStartTime) / 1000 . " ms";
$output['data'] = [];

mysqli_close($conn);

echo json_encode($output);

exit;
}


if (isset($_GET['editDepartment'])) {
$id = $_GET['editDepartment'];
$result = $conn->query("SELECT * FROM department WHERE id=$id") or die(mysqli_error($conn));
$update = true;
if (!$result) {

    $output['status']['code'] = "400";
    $output['status']['name'] = "executed";
    $output['status']['description'] = "query failed";
    $output['data'] = [];

    mysqli_close($conn);

    echo json_encode($output);

    exit;
} else {
    $row = $result->fetch_array();
    $department = $row['name'];
    $location = $conn->query("SELECT locationID FROM department WHERE id=$id") or 
  die(mysqli_error($conn));
  }
   };

使用Ajax时，当锚标记单击send Ajax request to PHP script并返回一个json数组和输出，并将其附加到modal，然后调用modal.show（）时，我在PHP脚本中没有看到任何关于
edit
参数的get请求。使用
die（mysqli_error（$conn））是一个非常糟糕的主意
在您的代码中，因为它可能会泄漏敏感信息。更多解释请参见本帖：谢谢大家的帮助！！！
