Re: Retrieving URL of webpage etc.

Ok, will try out that one.

Basically you're saying that the PHP backend will automatically make those 
checkboxes into an array if I implement that syntax?

There is really only one other form field on that page - a search textbox - 
apart from the possible 50 checkbox fields, but will definitely look into 
it.

Stay well
