Hi,

BuddyPress use templates to show his stuff.
The registration is part of WP and BP’s xprofile component add only some additionnal fields to the original register form.

If you open a template file you will see a lot of code and many lines starting by do_action( ‘something’ );

These files are all stored in bp-templates/bp-legacy/buddypress/

Now you have already the where and the what. here’s the how.

To show some text on the register page you have two options:
1) altering the whole template file bp-templates/bp-legacy/buddypress/members/register.php
2) add what you want by using an action hook

The second method is the fasted and the easiest. You just need to write a function and you’re done.

function valeriemanne() {
   echo 'Here i am !';
}
add_action( 'bp_before_register_page', 'valeriemanne' );

Add this to your child theme functions.php file or into bp-custom.php
