文件（图像）在codeigniter中上传问题

Question

实际上，我已经在前端显示后保存了数据库中的所有数据，在我身边的问题是我已经创建上传图像功能来保存数据库，我获取并显示前端，上传功能正在保存完整路径如：C：/xampp/www/htdocs/rentozy/admin/images/media/rajkumar-1515559187/1.jpg。所有图像保存文件夹也在前端只是这样：C：/xampp/www/htdocs/rentozy/admin/images/media/rajkumar-1515559187/1.jpg请我需要保存这样的数据库:(图片/media/rajkumar-1499778784/19510.jpg）请帮我解决这个问题，这是我第一次坐的是codeigniter请帮忙如何通过这个网址。

这是我的控制器代码：

function addNewMedia()
    {
        if($this->isAdmin() == TRUE)
        {
            $this->loadThis();
        }
        else
        {
            $this->load->library('form_validation');
            $this->form_validation->set_rules('name','Name','trim|required|max_length[128]|xss_clean');
            $this->form_validation->set_rules('event_image','Pg Image');
           // $this->form_validation->set_rules('media_image','Image');
           // $this->form_validation->set_rules('date_added','Date','trim|required');

            if($this->form_validation->run() == FALSE)
            {
                $this->addNew();
            }
            else

               // print_r($folder_srting);
                $folder_string = str_replace(' ', '-', $folder_srting);// Replaces all spaces with hyphens.
                $folder_string = preg_replace('/[^A-Za-z0-9\-]/', '', $folder_srting);// Removes special chars.
                $folder_name   = preg_replace('/-+/', '-', strtolower($folder_string));// Replaces multiple hyphens with single one.

                }

                redirect('mediaListing');
            }
        }
    }

这是我的模特：

 function addNewMedia($mediaInfo)
    {
        $this->db->trans_start();
        $this->db->insert('tbl_master_property', $mediaInfo);

        $insert_id = $this->db->insert_id();

        $this->db->trans_complete();

        return $insert_id;
    }

function getMediaInfo($eventId)
    {
        $this->db->select('pg_id, name,event_image,pg_address,pg_incharge_name,pg_incharge_mobile,pg_email,folder_name');
        $this->db->from('tbl_master_property');
        $this->db->where('status', 0);
        $this->db->where('pg_id', $eventId);
        $query = $this->db->get();

        return $query->result();
    }
function editMedia($mediaInfo, $eventId)
    {
        $this->db->where('pg_id', $eventId);
        $this->db->update('tbl_master_property', $mediaInfo);
        return TRUE;
    }

这里我的视图文件代码：

<?php
define("IMAGE_PATH", "http://localhost/rentozy/admin/");

$eventId = '';
$name = '';
$pg_address = '';
$pg_incharge_name = '';
$pg_incharge_mobile = '';
$pg_email ='';
$event_image = '';
$folder_name = '';




if(!empty($mediaInfo))
{
    foreach ($mediaInfo as $ef)
    {
        $eventId = $ef->pg_id;
        $name = $ef->name;
        $pg_address = $ef->pg_address;
        $pg_incharge_name = $ef->pg_incharge_name;
        $pg_incharge_mobile = $ef->pg_incharge_mobile;
        $pg_email = $ef->pg_email;
        $event_image = $ef->event_image;
        $folder_name = $ef->folder_name;


    }
}

我不知道你是否考虑过它，但是你可以轻松地使用PHP的str_replace来做你需要的。

<?php

$path = $upload_data['banner_data']['full_path'];

$dir = 'C:/xampp/www/htdocs/rentozy/admin/';

$url = str_replace( $dir, '', $path );

echo $url;

在CodeIgniter中，如果要保存到文档根目录之外的路径，则可以使用FCPATH常量来简化此操作。因此，如果您上传文件夹的路径位于名为/uploads/的目录中，而/uploads/位于文档根目录，那么：

<?php

$path = $upload_data['banner_data']['full_path'];

$dir = FCPATH . 'uploads/';

$url = str_replace( $dir, '', $path );

echo $url;

这只是一个例子，但很容易
