This is a lightweight php upload script for uploading files to a web server. This is probably as lightweight as it is going to get. Simply drop the file in, do some light configuration, configure ShareX to upload to it, and off you go.
Open up the upload.php file, or whatever you named it to. On the 2nd line of the file there is a line called $secret_key, change this. Preferably make it completely random. This is the key used to authorize uploads.
Next we have to look at the path variables:
$domain_url is the url path to the files.
$folder_destination is the path to the files on the file system.
When it comes to folder destination, leaving it blank will cause it to put uploaded files in the same folder as the upload script.
If your upload file is in the root directory folder, meaning it's accessible from the web at https://example.com or https://subdomain.example.com, then you do not need to change the $domain_url. $_SERVER['HTTP_HOST'] grabs the domain and subdomain (if you are on one) of the url you used to upload the image, and will automatically use that domain.
Uploader path: https://example.com/upload.php
Path where files are accessible: https://example.com/file.ext
Filesystem uploader path: /var/www/html/upload.php
Filesystem file storage path: /var/www/html
Configuration:
$domain_url = "https://".$_SERVER["HTTP_HOST"];
$folder_destination = '';
If for whatever reason the upload url domain that you use to upload files is different from the one you want people to use to access the files and images from, replace the $domain_url with "https://whateverurlyou.want". Do not leave a trailing forward slash or the url returned will become https://whateverurlyou.want//name.ext
Uploader path: https://example.com/upload.php
Path where files are accessible: https://files.example.com/file.ext
Filesystem uploader path: /var/www/html/upload.php
Filesystem file storage path: /var/www/files
Configuration:
$domain_url = "https://files.example.com";
$folder_destination = '/var/www/files/';
If you do not want your files in the root directory of the domain / subdomain, simply modify the $folder_destination variable. If for instance your upload file is in the root directory of the domain, and can be accessed from https://example.com/upload.php but you want your files accessed like https://example.com/files/file.ext, simply put files/ in the $folder_destination and add ."/files" after the domain string. Make sure you include the trailing slash or else your files will upload at https://example.com/filesfile.ext.
Example:
Uploader path: https://example.com/upload.php
Path where files are accessible: https://example.com/files/file.ext
Filesystem uploader path: /var/www/html/upload.php
Filesystem file storage path: /var/www/html/files
Configuration:
$domain_url = "https://".$_SERVER["HTTP_HOST"]."/files";
$folder_destination = "files/";
Your domain you use to upload is different from the one you share, and on top of that the files are not in the root directory of the shared domain. On the file system, the uploader is located at /var/www/html/uploader.php, but the filesystem path of the file system is located at /var/www/fileserver/bruh.
Example:
Uploader path: https://127.0.0.1/uploader.php
Path where files are accessible: https://fucking.fuck-o.ff/bruh/file.ext
Filesystem uploader path: /var/www/local/uploader.php
Filesystem file storage path: /var/www/fuckingfuckoff/bruh
Configuration:
$domain_url = "https://fucking.fuck-o.ff/bruh";
$folder_destination = '/var/www/fuckingfuckoff/bruh/';
After you have configured the upload script it is time to configure the upload script. Simply the steps below:
For your after capture tasks, make sure the only thing ticked is upload image to host:
Next, for after upload tasks, make sure only copy url to clipboard is ticked:
Next, in destinations, set your image uploader and file uploader to "Custom image uploader"
You should see something like this:
After that, if it didn't automatically do this set the image and file uploader to custom uploader and press "test". If it worked, then everything was setup right. If you are receiving a failed upload error, look below.
If you receive a message stating File upload failed - The maximum file size limit is... etc, there are a few things that could of happened. If the size of your file is larger than the maximum post size or upload file size, then you need to increase the limit in your php config.
Go into the config (on my install it was located in /etc/php/7.4/apache2 and find the post_max_size variable, set it to something like 128M. Then go to the upload_max_filesize variable and set it to 128M as well or whatever you want, just as longer as it's bigger than what you are trying to or planning to upload in the future. After this, restart apache, nginx, or whatever web server you are running.
If you are still getting the error then the next thing that could of gone wrong is that there are permission issues. On ubuntu (which is what I use) you need to make sure that the user apache is running on can write to the folder. You can give ownership to the apache user by running chown -R www-data:www-data /var/www. This grants ownership to the apache user to everything in the www-data folder, which can sometimes get messed up if you modify the folder with other users. On other linux distros the apache user might be apache2.
