Question

请帮助我将用户1的图像更新为abc.jpg然后如果我更新用户2的爱好，那么它的个人资料pic被用户1图像替换不知道为什么？

public function multiple_image_upload()
        {
            $config = array();
            $config['upload_path']          = './uploads/user_avatars/';
            $config['allowed_types']        = 'gif|jpg|png';
            $config['max_size']             = 10000;
            $config['max_width']            = 10240;
            $config['max_height']           = 7680;

            $images = array();
            $count = (count($_FILES['avatar']['name'])>0);
            if($_FILES['avatar']['name']!= Null && ($count = count($_FILES['avatar']['name'])) > 0)
                //using this its working fine but my images are overlapped

            {
                $files = $_FILES;
                $images = array();
                /* check if folder with year exists*/
                $current_year = date('Y');
                $path = './uploads/user_avatars/'.$current_year;

                if(is_dir($path)){
                    /* do nothing */
                }else{
                    /* create directory */
                    @mkdir( $path , 0755, true );
                }

                $images = array();
                for($i = 0; $i < @$count; $i++) 
                {
                    $config['upload_path'] = $path;
                    $config['allowed_types'] = 'gif|jpg|jpeg|png';
                    $config['max_size'] = '100000';
                    $config['max_width']  = '102400';
                    $config['max_height']  = '76800';
                    $this->load->library('upload', $config);

                    if ($this->upload->do_upload('avatar'))
                    {
                        $data = $this->upload->data();

                        /* create thumbnail */
                        $this->load->helper('image_thumb_helper');
                        generate_image_thumb($data['full_path'],$path,$data['file_name']);

                        /* add to database */                   
                        $images[$i]['file_name'] = $current_year.'/'.$data['file_name'];
                        $images[$i]['thumb'] = $current_year.'/thumb_'.$data['file_name'];
                    }else{
                        $this->form_validation->set_message('multiple_image_upload',$this->upload->display_errors());
                        return false; 
                    }    
                }

                $this->session->set_userdata('uploaded_images',$images);
                return true;
             }
            else{

              return true;
            }
        }

以上是我需要帮助解决此问题的代码

    if($_FILES['avatar']['name']!= Null && ($count = count($_FILES['avatar']['name'])) > 0)

主要问题在于我猜，但不确定

Answer 1

首先，检查$ count变量的计数。然后保持在下面如果（$ _ FILES ['avatar'] ['name']！= NULL＆amp;＆amp; count（$ _ FILES ['avatar'] ['name']）＆gt; 0）

我不知道你为什么要使用for循环？如果它们只是一个图像，则$ i将为0.因此，它总是被第一个替换。

在codigniter中重叠图像
