Download jQuery file from bluimp, how to replace instead of renaming

First of all, the jQuery plugin can be found here:

https://github.com/blueimp/jQuery-File-Upload

I am using the PHP version of the script and I am trying to replace images with the same name instead of renaming them.

I think I found functions that rename, but the fixes I tried do not work.

protected function upcount_name_callback($matches) { $index = isset($matches[1]) ? intval($matches[1]) + 1 : 1; $ext = isset($matches[2]) ? $matches[2] : ''; return ' ('.$index.')'.$ext; } protected function upcount_name($name) { return preg_replace_callback( '/(?:(?: \(([\d]+)\))?(\.[^.]+))?$/', array($this, 'upcount_name_callback'), $name, 1 ); }

Any suggestions? I searched everywhere, but to no avail.

Link to the php class that is loading: https://github.com/blueimp/jQuery-File-Upload/blob/master/server/php/upload.class.php

Any suggestions?

Edit:

I tried to just return null for these functions, but it just hangs the script, perhaps because it does not know what to do if the file name matches.

You can change your side of the PHP script server so that the files are overwritten instead of creating a new unique file name. Just change the get_file_name load handler class function:

Original Function:

  protected function get_file_name($file_path, $name, $size, $type, $error, $index, $content_range) { $name = $this->trim_file_name($file_path, $name, $size, $type, $error, $index, $content_range); return $this->get_unique_filename( $file_path, $this->fix_file_extension($file_path, $name, $size, $type, $error, $index, $content_range), $size, $type, $error, $index, $content_range ); }

change this to the following:

 protected function get_file_name($file_path, $name, $size, $type, $error, $index, $content_range) { $name = $this->trim_file_name($file_path, $name, $size, $type, $error, $index, $content_range); return $name; }

Thus, the existing file will be overwritten if the downloaded file name is the same as the existing file on your server.

Use this custom function in the index.php file, requiring UploadHandler.php

 protected function trim_file_name($file_path, $name, $size, $type, $error, $index, $content_range) { // Remove path information and dots around the filename, to prevent uploading // into different directories or replacing hidden system files. // Also remove control characters and spaces (\x00..\x20) around the filename: $name = trim(basename(stripslashes(unique_custom_file_name)), ".\x00..\x20"); // Use a timestamp for empty filenames: if (!$name) { $name = str_replace('.', '-', microtime(true)); } return $name; }

you can also use rewrite as an option as follows:

 $options = array( 'overwrite' => $overwrite ); $upload_handler = new UploadHandler($options);

in UploadHandler.php: add default parameter

  function __construct($options = null,...){ ... 'overwrite' => false, ... }

then replace the get_file_name () function with

  protected function get_file_name($file_path, $name, $size, $type, $error, $index, $content_range) { $name = $this->trim_file_name($file_path, $name, $size, $type, $error, $index, $content_range); if($this->options['overwrite']) return $name; else return $this->get_unique_filename( $file_path, $this->fix_file_extension($file_path, $name, $size, $type, $error, $index, $content_range), $size, $type, $error, $index, $content_range ); }
