tinymce插件上传图片

I am using the plugin for tinymce to upload images (justboil.com)

i am uploading the images on

sub.domain.com/upload.php

and the upload folder is located at

domain.com/file_dump/tinymce_file_upload

i have put this in my config

$config['img_path'] = '/file_dump/tinymce_file_upload'; // Relative to domain name
$config['upload_path'] = substr($_SERVER['DOCUMENT_ROOT'],0,-3) . $config['img_path']; // Physical path. [Usually works fine like this]

it gets the DOCUMENT_ROOT and removes 3 characters (for the subdomain) as the sub folder for the sub domain is located in the public_html folder

i am getting an error saying the upload path is invalid when i try to upload images

your upload path looks with '//' domain.com//file_dump/tinymce_file_upload

so Just remove '/' from $config['img_path']

$config['img_path'] = 'file_dump/tinymce_file_upload';
