在CodeIgniter中使用搜索过滤器进行分页

时间：2020-09-15 12:37:38

标签： codeigniter

当我搜索关键字并对其分页时，它会返回与数据库中类似查询匹配的数据。

遇到PHP错误 严重程度：警告

消息：count（）：参数必须是实现Countable的数组或对象

文件名：admin / view_member.php

行号：105

您似乎没有返回要计数和循环的数组，这就是发出警告的原因。

此外，您的循环中还有失败的消息，以后将出现更多错误。 希望这对您有帮助并为您工作

<?php
if (!$users || !is_array($users)) {
  // Faild Message
  echo $this->session->flashdata('recoard');
