Re: How can I echo a javascript var in an email subject line? Possible? (Yes!)

For me its very easy to pass php values to the client: echo _var($value,'name'); But the best part is taking control of what your client sees from the server-side: C('#info')->show(); // now you see it .. C('#info')->hide(); // now you don't! Take control and start building powerful web apps with Raxan PDI - http://raxanpdi.com __ Raymond Irving Create Rich Ajax/PHP Web Apps today!
