Re: [PHP] 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 -
