Undefined index after posting when JavaScript is disabled

Hello,

I was testing my form with JavaScript disabled, and got a PHP error saying “Undefined index” for my hidden field, using this plugin. The error came from this line, and looking at the $_POST array at that point, it only had the initial four WPCF7 fields.

I fixed the error by changing the if condition from:
if ( wpcf7_is_posted() )
To:
if ( wpcf7_is_posted() && isset( $_POST[$name] ) )

This is the check that the Contact Form 7 plugin does for text fields, see this line.

Might this be a fix that should be included in the next version of your plugin, or was something else broken on my side to begin with?
