Question

此脚本可能有什么问题？

<?php
// json response array
$response = array("error" => FALSE);
if (isset($_POST['amountApplied']) && isset($_POST['mop']) && isset($_POST['term']) && isset($_POST['lastname']) && isset($_POST['firstname']) && isset($_POST['middlename']) && isset($_POST['birthdate']) && isset($_POST['age']) && isset($_POST['sex']) && isset($_POST['status']) && isset($_POST['marriageDate']) && isset($_POST['noChildren']) && isset($_POST['nationality']) && isset($_POST['acr']) && isset($_POST['address']) && isset($_POST['cityMunicipality']) && isset($_POST['province']) && isset($_POST['telNo']) && isset($_POST['years']) && isset($_POST['offAddress']) && isset($_POST['offCityMunicipality']) && isset($_POST['offProvince']) && isset($_POST['offTelNo']) && isset($_POST['offYears']) && isset($_POST['busAddress']) && isset($_POST['busCityMunicipality']) && isset($_POST['busProvince']) && isset($_POST['busTelNo']) && isset($_POST['busYears']) && isset($_POST['productServiceOffered'])) {

错误：

致命错误：未捕获错误：调用未定义的方法第44行上的DB_Connect :: storeClient（）。

我无法真正分辨出脚本出了什么问题。我只是在教程中得到了这个脚本，并逐步研究了它。任何帮助，技巧和协助将不胜感激。预先感谢

这是DB_Connect

<?php
class DB_Connect {
    private $conn;


// Connecting to database
public function connect() {
    require 'include/Config.php';

    // Connecting to mysql database
    $this->conn = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE);

    // return database handler
    return $this->conn;
}
}

?>

Answer 1

您仅实例化DB_Connect对象，但从未调用连接。

所以：

...
require 'include/DB_Connect.php';
$db = new DB_Connect();
$db->connect();
$result = $db->storeClient ...

这应该可以解决问题：）

PHP：致命错误：未捕获错误：调用未定义的方法DB_Connect :: storeClient（）
