 * Hi

   plugins functions?
 * Thanks in advance

 * Just to expand a bit more.
 * I’m trying to write a plugin that hooks into Contact Form 7’s submit function.
   There are many extensions for this plugin, so perhaps someone can just give me
   a brief idea of how to do it?
 * Thanks

 * //example
 * function hello_world(){
    echo ‘Hi World!’; } add_action(‘the_post’,’hello_world’);
 * //where the ‘the_post’ is the hook and the ‘hello_world’ is the function to be
   executed.

 * Thanks dunhakdis
 * That’s for plugging into WordPress, but what I was really looking for I managed
   to find last night after sifting through a lot of code.
 * To hook into ANOTHER plugin – in this case it was contact form 7 – and indeed
   it was as easy as plugging into wordpress:
 * `add_action('wpcf7_before_send_mail', 'my_function');`
 * Thanks for your help though 🙂

 * You can hook into any functions as long as it is supported though 🙂
