Question

美好的一天，我是PHP的新手，我真的需要一些帮助。我在插入数据后试图在新页面中发出确认消息。我试着回声并打印出结果，但对我来说没什么用!!!!这是我遇到的唯一一个我无法解决的问题!!!

request.php 页面的代码：

<!DOCTYPE html>
<html>

<head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>

</head>

<body dir="rtl">
    <div class="container" style="width:400px;">
        <div ng-app="myapp" ng-controller="formcontroller">

req_add.php 页面的代码:(将数据插入数据库）

<?php
//req_add.php
$connect = mysqli_connect("localhost", "root", "", "testing");
$form_data = json_decode(file_get_contents("php://input"));
mysqli_query($connect,'set names utf8') or die (mysqli_error($connect));
$data = array();
$error = array();
$date1 = date('Y/m/d H:i:s');// 2017-07-12 10:35:45
 $today = date("Ymd");
$rand = strtoupper(substr(uniqid(sha1(time())),0,4));
$no1 = $today . $rand;  


if(empty($form_data->name))
{
 $error["name"] = "name is required";
}
if(empty($form_data->em))
{
 $error["em"] = "email is required";
}
if(empty($form_data->telph))
{
 $error["telph"] = "mobile number is required";
}
if(empty($form_data->dept))
{
 $error["dept"] = "department is required";
}
if(empty($form_data->det))
{
 $error["det"] = "details are required";
}
if(!empty($error))
{
 $data["error"] = $error;
}
else
{

      $name = mysqli_real_escape_string($connect, $form_data->name);
      $em = mysqli_real_escape_string($connect, $form_data->em);  
      $telph = mysqli_real_escape_string($connect, $form_data->telph);  
      $dept = mysqli_real_escape_string($connect, $form_data->dept);  
      $det = mysqli_real_escape_string($connect, $form_data->det);
      $no = mysqli_real_escape_string($connect, $form_data->no1);
     $reqdate = mysqli_real_escape_string($connect, $form_data->reqdate);
     $answer = mysqli_real_escape_string($connect, $form_data->answer);

$query = "INSERT INTO requests(name, em, telph, dept, det, no, reqdate, answer) VALUES ('$name','$em', '$telph', '$dept', '$det', '$no1', '$date1', 'no answer')"; 

 if(mysqli_query($connect, $query))
 {
 $data["message"] = "thank you for your request, your request nymber is: " .$no1;
 }
} 
echo json_encode($data);

?>

一个有用的选项是使用mysqli_insert_id来插入最后一个ID 此函数获取DB中的最后一个id，不仅在insert表中，而且足够了。

另一种是手动形式，查询返回自定义值在您的代码中：

$query ="INSERT INTO requests(name, em, telph, dept, det, no, reqdate,answer) 
          VALUES ('$name','$em', '$telph', '$dept', '$det', '$no1','$date1', 'no answer')";

 if(mysqli_query($connect, $query))
 {
 $data["message"] = "thank you for your request, your request nymber is: " .$no1;
 }
} 
echo json_encode($data);

添加此更改：

$query = "INSERT INTO requests(name, em, telph, dept, det, no, reqdate, answer) 
         VALUES ('$name','$em', '$telph', '$dept', '$det', '$no1', '$date1', 'no answer')";
$query .="; select 1 as insert_ok;";

 if($stmt=mysqli_query($connect, $query)) // Get result
 {
     $fetch = mysql_fetch_object($stmt);

        if ($fetch->insert_ok) {
          $data["message"] = "thank you for your request, your request nymber is: " .$no1;
        }else{
            $data["message"] = "The register wasn't inserted";

 } // else
}  //if $stmt
echo json_encode($data);

在您的脚本代码中：验证从php脚本返回的insert_ok值。
