Uploading to nginx using the nginx upload module with php_handler

I have been searching a long time how to get the upload_handler from the verybasic example to work with the nginx uploadmodule. So here is my solution:

First my nginx.conf file :

server {
    client_max_body_size 4G;
    client_body_buffer_size 1024k;
    listen 80;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm index.php;

    # Make site accessible from http://localhost/
    server_name localhost;

    location @frontcontroller {
        rewrite ^ /index.php last;
    }

    location = /progress {
        report_uploads uploads;
    }

    location /upload {
        # the location of the php handler
        upload_pass  /jQueryFileUpload/server/php/index.php;
        # the location where the files are uploaded
        upload_store	/var/tmp/fuploads;
        upload_store_access user:rw;
        upload_state_store /var/tmp/fuploads/state ;

        # Set specified fields in request body 
        # the field data will be available through the superglobal $_POST[]
        upload_set_form_field "${upload_field_name}_name" $upload_file_name;
        upload_set_form_field "${upload_field_name}_content_type" $upload_content_type;
        upload_set_form_field "${upload_field_name}_path" $upload_tmp_path;

        upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
        upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;

        upload_pass_form_field "^submit$|^description$";

        track_uploads uploads 5s;
    }

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ /index.html;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
    #    # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
    #
    #    # With php5-cgi alone:
    #    fastcgi_pass 127.0.0.1:9000;
    #    # With php5-fpm:
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
}

Once this is done you have to open up the verybasic.php file and look for the input field - the name of the input field will be the prefix name in our $_POST[] variable.

I call mine simple “files”:

<input id="fileupload" type="file" name="files" data-url="/upload" >

Then the last step is to adapt the Uploadhandler.php.

1. Replace the post function.

You can delete everything in the post function and replace it with something like this:

public function post($print_response = true) {
    $prefix = files; //our name of the input field 

    if (isset($_REQUEST['_method']) && $_REQUEST['_method'] === 'DELETE') {
        return $this->delete($print_response);
    }

    $files = array();
    $files = $this->new_handle_file_upload($prefix);

    return $this->new_generate_response(array('files' => $files));
}

1. As you can see in the above code, we have to add two new functions:

protected function new_handle_file_upload($prefix) {
    $file = new stdClass();
    $file->name = $_POST[$prefix."_name"];
    $file->type = $_POST[$prefix."_content_type"];		
    $file->url = $_POST[$prefix."_path"];
    $file->size = $_POST[$prefix."_size"];
    $file->error = 'success';
    $this->set_additional_file_properties($file);
    $s[]=$file;		
    return $s;
}

protected function new_generate_response($content) {
    $this->head();
    $json = json_encode($content);
    $this->body($json);
    return content;
}

This is it , hopefully a lot of people will enjoy it.

Thank you
