Some users on social sites still enter their email addresses on comment fields. I'm trying to prevent spammers from harvesting them by replacing the @ character with a graphic. That's really easy to do using the smiley module.

However, I use the text filter option "Convert URLs into links" which turns the email into a mailto link. The smiley filter now breaks the HTML.

I would like to not turn emails into links but keep turning urls into links. How could I do that?

The easiest way is to creat your own input filter. Do a PREG and obfuscate the email address. Assign this filter to your input formats, and make sure it runs before the URL-to-link one.

  • thanks. I don't think I could obfuscate it with a graphic if it gets turned into a link afterwards. I could replace @ with @ but but that could be hacked easily – uwe Feb 19 '13 at 6:38
  • Definitely, a custom input filter is by far the easiest solution – Clive Feb 19 '13 at 9:39
  • @MotoTribe If you obfuscate it before the URL-to-link filter runs, then it shouldn't get turned into a link. Look at the code for _filter_url. If the "@" isn't there, then it' won't match. – mpdonadio Feb 19 '13 at 12:09

Spamfree email module replaces email address with mailto links and obfuscates to js code for js supporting browsers and to image for non js browser thus preventing email harvest bots.
