Re: [SMARTY] Modifier with preg_replace_callback

The Smarty mailto function has some obfuscation built-in.

Well, yes, this would be very helpful if I just had some email address=20=

I wanted to generate a mailto from. My problem is that the email=20
addresses are scattered throughout the text like this:

$text=3D	"This is the content of my website.
More stuff ...
If you want to contact me, write to: myemail@myserver.de
You can also write a letter to ...";
$smarty->assign("text",$text);

So I think I HAVE to use some regex_replace in a custom modifier. So=20
here is my problem again: The function I defined for the callback=20
doesn't get called.

Silly question, but have you checked the code outside Smarty? Eg: if there
were no matches being found based on your regexp, then the callback wouldn't
be called, so have you tested the same functions with known search text?

What happens if you subsitute the preg_replace_callback with preg_replace?
(As it stands you should get your email addresses changed to the text
"escape_mail"; if it doesn't either your regexp is wrong (looks ok to me) or
the input text doesn't look the way you thought it did.

Sorry if I'm teaching you to suck eggs here...

Thank you for your suggestions. I've tried them all with no result,=20
changed something in the template - and voil=E0 everything worked. The=20=

Smarty-cache has tricked me again :-( What a great feature and what a=20
great source of frustration!

Thank you all for trying to help me. The function I posted works as I=20
thought.
