我正在尝试使用参数 $data 从构造函数加载视图。早些时候它工作正常,现在突然停止工作。下面是代码:

权限错误查看

    <table width="100%" border="0" cellpadding="0" cellspacing="0">
              <tr>
                <td width="6" align="left" valign="top" background="<?php echo base_url();?>images/bg/topbg.gif"><img src="<?php echo base_url();?>images/bg/top-left.gif" width="5" height="34" /></td>
                <td height="34" align="left" valign="middle" background="<?php echo base_url();?>images/bg/topbg.gif" class="heading">Access Forbidden</td>
                <td width="6" align="right" valign="top" background="<?php echo base_url();?>images/bg/topbg.gif"><img src="<?php echo base_url();?>images/bg/top-right.gif" width="5" height="34" /></td>
              </tr>
              <tr>
                <td align="left" valign="top" background="<?php echo base_url();?>images/bg/main-content-bg-left.gif">&nbsp;</td>
                <td height="165" valign="top"  bgcolor="#FFFFFF" class="leftredheading"><div style="margin:30px auto;padding-left:15px"><? if(isset($sn_error)) echo $sn_error;?></div></td>
                <td align="right" valign="top" background="<?php echo base_url();?>images/bg/main-content-bg-right.gif">&nbsp;</td>
              </tr>
              <tr>
                <td align="left" valign="bottom" background="<?php echo base_url();?>images/bg/bottom-bg.gif"><img src="<?php echo base_url();?>images/bg/bottom-left-corner.gif" width="5" height="5" /></td>
                <td valign="top" background="<?php echo base_url();?>images/bg/bottom-bg.gif"></td>
                <td align="right" valign="bottom" background="<?php echo base_url();?>images/bg/bottom-bg.gif"><img src="<?php echo base_url();?>images/bg/bottom-right-corner.gif" width="5" height="5" /></td>
              </tr>
            </table>

Template code:

<?php $this->load->view('includes/login/header'); ?>
<table width="100%" border="0" cellpadding="0" cellspacing="0" bgcolor="#e7e7de">
  <tr>
    <td width="18"><img src="<?php echo base_url();?>images/bg/zero.gif" width="18" height="1" /></td>
    <td width="191"><img src="<?php echo base_url();?>images/bg/zero.gif" width="191" height="1" /></td>
    <td width="18"><img src="<?php echo base_url();?>images/bg/zero.gif" width="18" height="1" /></td>
    <td width="100%">&nbsp;</td>
    <td width="161"><img src="<?php echo base_url();?>images/bg/zero.gif" width="18" height="1" /></td>
    <td width="191"><img src="<?php echo base_url();?>images/bg/zero.gif" width="191" height="1" /></td>
    <td width="18"><img src="<?php echo base_url();?>images/bg/zero.gif" width="18" height="1" /></td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td align="left" valign="top"><table width="191" border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td background="<?php echo base_url();?>images/bg/left-menu-white-bg.gif"> <?php $this->load->view('includes/login/top_right'); ?> </td>
      </tr>
      <tr>
        <td height="50" background="<?php echo base_url();?>images/bg/left-menu-white-bg.gif">&nbsp;</td>
      </tr>
      <tr>
        <td background="<?php echo base_url();?>images/bg/left-menu-white-bg.gif"><table width="166" border="0" align="center" cellpadding="0" cellspacing="0">
          <tr>
            <td align="left" valign="top"><img src="<?php echo base_url();?>images/bg/needhelp-top.gif" width="166" height="7" /></td>
          </tr>
          <tr>
            <td align="center" valign="top" bgcolor="#F8F7EC"> <?php $this->load->view('includes/login/bottom_right'); ?>
                <br /></td>
          </tr>
          <tr>
            <td align="left" valign="top" bgcolor="#F8F7EC"><img src="<?php echo base_url();?>images/bg/needhelp-bottom.gif" width="166" height="7" /></td>
          </tr>
        </table>
          <br /></td>
      </tr>
      <tr>
        <td background="<?php echo base_url();?>images/bg/left-menu-white-bg.gif"><table width="191" border="0" cellspacing="0" cellpadding="0">
          <tr>
            <td height="6" align="left" valign="top"><img src="<?php echo base_url();?>images/bg/left-bttom.gif" width="6" height="6" /></td>
            <td width="100%" background="<?php echo base_url();?>images/bg/leftbottom.gif"></td>
            <td height="6" align="right" valign="top"><img src="<?php echo base_url();?>images/bg/right-bttom.gif" width="6" height="6" /></td>
          </tr>
        </table></td>
      </tr>
    </table>
         <br /></td><td>&nbsp;</td>
    <td valign="top"  <? if($main_content != 'dashboard' || $main_content == 'publisher_dashboard') { ?> colspan="3" <? } ?>><?php $this->load->view($main_content); ?></td>
    <td>&nbsp;</td>
    <? if($main_content == 'dashboard' || $main_content == 'publisher_dashboard') { ?>
    <td align="right" valign="top"> <?php $this->load->view('includes/login/left'); ?>
    </td>
    <? } ?>
    <td>&nbsp;</td>
  </tr>
</table>
<?php $this->load->view('includes/login/footer'); ?>

在上面的代码中,我正在检查登录用户是否具有访问权限,然后通过 if case 块中的错误执行 else 部分。

在 IF 情况下,它会加载错误模板。

请有人帮我尽快解决上述问题!

打电话parent::__construct(),不是parent::Controller()

编辑:

在明确使用 CodeIgniter 1.7.1 并显示视图本身之后,这是您的问题:

您的视图尝试回显$error而不是$sn_error. 如果您不传递$data给视图,则$sn_error(已检查)未设置并且不会发生该错误 - 这就是在这种情况下加载视图的原因。
