Encoded email addresses (obfuscation)

There is a simpler way to accomplish such the subject thing, unfortunately pages within TXP are rendering into UTF-8 characters (converted):

<a href="mailto:user&commat;domain&period;com">user&commat;domain&period;com</a>

That is rendering as this:

<a href="mailto:user@domain.com">user@domain.com</a>

Without any obfuscation 😭

So, here is an another (a little bit complex) way. Copy/Past into an email form:

<txp:if_yield name="email"><txp:variable name="email" value='<txp:yield name="email" />' /><txp:php>
global $variable;

for ($i = 0; $i < strlen($variable['email']); $i++) {
	$variable['encoded'] .= '&#'.ord($variable['email'][$i]).';';
}

</txp:php><txp:if_yield name="link"><a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;<txp:variable name="encoded" />"><txp:variable name="encoded" /></a><txp:else /><txp:variable name="encoded" /></txp:if_yield><txp:variable name="email" value="" /></txp:if_yield>
<txp:variable name="encoded" value="" />

Note: the last variable is required to remove its content (in a multiple use case of this shortcode into a same article).

<txp::email email="user@domain.com" />

<txp::email email='<txp:author_email />' link />

The link attribute is optional and governs the rendering of a full cliquable link.

I did too, and I made a plugin out of the standalone php version of the algorithm. You can get it here and use it just like the built-in tag. See the docs for attributes and options.

More thanks – I didn’t know about the plugin either. I used Enkoder years ago when it had a web page. It really works. Great to have this for Textpattern.
