I was looking for a simple way to ban html from review posts, and the like. I have seen a few
classes to do it. This line, while it doesn't strip the post, effectively blocks people from
posting html in review and other forms.
<?php
if (strlen(strip_tags($review)) < strlen($review)) {
return false;
}
?>
If you want to further get by the tricksters that use & for html links, include this:
<?php
if (strlen(strip_tags($review)) < strlen($review)) {
return false;
} elseif ( strpos($review, "&") !== false) {
return 5;
}
?>
I hope this helps someone out!
