For checkbox's I like to have a HIDDEN checkbox.







With the hidden name and value, I'll always have at least a blank form

Re: [PHP] transformation to htm file when downloaded

[Daniel Clark]

The PHP code is processed on the web server and removed.   Only the HTML
and images are sent back to the clients browser.

Re: [PHP] why doesn't this work ?

[Daniel Clark]

The browser doesn't know what to do with PHP code.
