    $this->load->library('form_validation'); 
    $config_image = array(
     'upload_path' => './uploads/',

     redirect('index.php/Memberlogincontroller/getMember/'.$id, 'refresh');  
    }  
    } 
    } 

如何显示我的默认图像？

Answer 1

只需添加一个条件来检查图像是否可用。如果是显示用户的图像，则显示默认图像。

<?php 
$user_img = !empty($this->session->userdata('image')) ? $this->session->userdata('image') : 'no-avatar.jpg'; 
?> 
<img height="180px" width="180px" class="ppborder" src="<?php echo base_url().'/uploads/'.$user_img; ?>">
