That would pass data to the view that would look something like message to a session variable to be displayed on the page after redirection. In the layout we have FlashHelper::render() which displays the message and clears the corresponding session variable. The controller’s

Useful functions followed by an identifier, which is a set of alphanumeric chars and the underscore _ char. A variable can be assigned any type of value, like strings (defined using single or double quotes): $name Once a variable is assigned a value, for example a string, we can reassign it a different type of value, like a number: $name = 3; PHP won’t complain that now the type is different. Variable names

process_request(self, req, resp): # req.stream corresponds to the WSGI wsgi.input environ variable, # and allows you to read bytes from the request body. # # See also: PEP 3333 application = falcon.API() That creates your WSGI application and aliases it as api. You can use any variable names you like, but we’ll use application since that is what Gunicorn expects it to be called, by let’s create a hook that will run before each request to post a message. Add this method below the definition of ALLOWED_IMAGE_TYPES: def validate_image_type(req, resp, resource, params): if req.content_type
