Question

请帮助我有一个问题：

致命错误：未捕获的错误：当不在 D:\xampp\htdocs\admin\antivirus\antivirus_scan.php:1 的对象上下文中时使用 $this
堆栈跟踪：
#0 {main} 在 D:\xampp\htdocs\admin\ 中抛出第 1 行的 antivirus\antivirus_scan.php

<?php $this->load->view('admin/theme/message'); ?>
<section class="content-header">
    <h1 class = 'text-info'><i class="fa fa-shield"></i> <?php echo $this->lang->line("malware scan");?></h1>
</section>
<section class="content">  
    <div class="row" >
        <div class="col-xs-12">
            <div class="grid_container" style="width:100%; height:720px;">
                <table 
                id="tt"  
                class="easyui-datagrid" 
                url="<?php echo base_url()."antivirus/scan_data"; ?>" 

                pagination="true" 
                rownumbers="true" 
                toolbar="#tb" 
                pageSize="10" 
                pageList="[5,10,15,20,50,100]"  
                fit= "true"
