CMS Made Simple Forums

I am not a proficient PHP coder (in fact less than a hack), but I need help to accomplish this:

Within a template I have set a hidden content block to capture an email address in the Page Editor, then pass it to the {mailto} Smarty, thus:
All well and good except that if the "email" block is empty, then I get an error, so I am wondering how to correctly code either the template or call some script in a User Defined Tag to only call the Smarty {mailto} if the $email1 isn't empty? 

I thought of doing something this:
But I don't know my PHP or smarty well enough to know how to form the {mailto} call within a PHP script - if it can be done.

Any help on this?  Thank you.  I am learning gobs but this one I have hit the wall of my own grasp of PHP syntax.

I'm not a coder for real too but I suggest you should use Smarty pure

Well there you go, I knew it would be something simple.  Thank you!

I am curious still, however, whether you can call or set up a smarty function with a parameter from within PHP and and example of just how you would code it.

You have to enable "Use smarty php tags" in config.php. Then you can use too in template
