我在使用带有ajax的php类时遇到了问题。 基本上我有index.php加载ajax example.php。 example.php包含init.php，后者又包含一堆类。我把它缩小到了我粘贴在下面的users.php类。我还把init.php放在它下面以防万一。
该文件不会使用ajax加载。如果我直接去它，它工作正常。

的init.php：
<?php
session_start();
require($_SERVER['DOCUMENT_ROOT'].'/core/connect/database.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/users.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/general.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/bcrypt.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/garage.php');
// error_reporting(0);
$users = new Users($db);
$general = new General();
$bcrypt = new Bcrypt(12);
$errors = array();
if ($general->logged_in() === true) {
$user_id = $_SESSION['id'];
$user = $users->userdata($user_id);
}
ob_start();
这是加载文件的js（它有点奇怪，因为它重新加载jscrollpane，但是使用html和php工作正常，需要外部类）：
// Ajax
$(function () {
var api = $("#garagecontent").jScrollPane().data('jsp');
var reinitialiseScrollPane = function()
{
api.reinitialise();
}
// attaching click handler to links
$(document).on('click', '#garagecontainer a[href]', function (e) {
// cancel the default behaviour
e.preventDefault();
// get the address of the link
var href = $(this).attr('href');
// getting the desired element for working with it later
var $wrap = $('#garagecontent');
$wrap
// removing old data
api.getContentPane()
// load the remote page
.load(href, reinitialiseScrollPane , function (){
}
);
});
});
我已将其缩小为users.php，因为当我从include（及其在init.php中的函数）中删除它时它会起作用。
有人能发现破坏我代码的内容吗？
答案 0 :(得分：0)
此问题的解决方案是使用自动加载器。由于调用了重复的类，页面正在破碎。我猜错了我的错误。
