Is it okay to leave a controller without a view?

[eluser]rvillalon[/eluser]
I have a controller for error logging and is accessible by the browser. For example, I can access it and log an error by going to:

http://www.mywebsite.com/error/save/acce...tl_details

The last three parameters are used as follows:
access_key : i match this in my config file to make thwart unwanted requests
error_id : unique id to store
addtl_details : additional error description

Once it validates the information, I save into a database but I don't have any "VIEW" set up. It simply returns a blank page.

Is this okay?

Also, does anyone have any tips on how I might improve this?

You call this controller using AJAX? Or what exactly do you do?

If you call it using AJAX, then it's fine if it does only return a blank page, no ones gonna see it anyway.
You don't have to use a view file, but as soon as you want to display content it's appropriate to do so, as a bunch of echo commands are pretty ugly xD

Thanks, waldmeister!

Also, what do you think of passing the access_key through flash? I included it to prevent unauthorized use of my error logger, but I think it can easily be sniffed for since it's coming from client-side.

Any thoughts?

Come to think about it, here's a better approach: Dynamically return file types through CI. This way, error logging can happen server-side.

For example,

http://www.mywebsite.com/request/xml/file_name

would return an XML file

Whereas,

http://www.mywebsite.com/request/image/file_name

returns an image file.

I could do this by making use of Header. ie: Header('Content-type: image/png'); If there's an issue loading the file, I can log the error then.

LOL Sorry for not thinking ahead!
