CodeIgniter Safe Email

How is this working exactly? This class converts all emails on the web page to "special tags", that web scrapers can't read. Most of the web scrapers can't run JavaScript. This class requires special jQuery plugin to convert "special tags" back to email addresses. This is the whole secret.

• Full automation
• No additional inline javascript
• No special helper calls in code

Installation

Copy application/hooks/Safe_email.php to your project.

Add below code to application/config/hooks.php file

$hook['post_controller'][] = array(
    'class'    => 'Safe_email',
    'function' => 'initialize',
    'filename' => 'Safe_email.php',
    'filepath' => 'hooks'
);

Enable hooks in your application/config/config.php file, by setting $config['enable_hooks'] variable to TRUE.

Add jQuery plugin from assets/js/jQuery.safeEmail.min.js to your project and load it like this:

$(document).ready(function() {
    $.safeEmail();
});

Configuration options

At this time only available configuration option is identifier for "special tags".

Default value is ci-safe-email, but this may be changed in Safe_email class. Just edit $class_name variable. If you change it, be aware that you need to initialize $.safeEmail call with additional option, like this: $.safeEmail({className: 'some-new-class-name'}).

Limitations

If web scraper is build on something like PhantomJS, this class won't help you.
