BuddyPress.org

Hi,

I want to send my users to the top of the page after they click on “Save changes” when editig their profile informations in buddypress. As I don’t want to modify the plugin’s core files, I looked for filters and found one in buddypress’ “functions.php”.
The thing is I absolutely don’t understand how this works. I spent 4 hours trying to sort this out but I’m giving up now.(I do understand how generic filters work though)
Here are the pieces of codes I have been looking at :

FUNCTIONS.PHP

function bp_nouveau_get_submit_button( $action = ” ) {
if ( empty( $action ) ) {
return false;
}

/**
* Filter the Submit buttons to add your own.
*
* @since 3.0.0
*
* @param array $value The list of submit buttons.
*
* @return array|false
*/
$actions = apply_filters( ‘bp_nouveau_get_submit_button’, array(
‘members-profile-settings’ => array(
‘before’ => ‘bp_core_xprofile_settings_before_submit’,
‘after’ => ‘bp_core_xprofile_settings_after_submit’,
‘nonce’ => ‘bp_xprofile_settings’,
‘attributes’ => array(
‘name’ => ‘xprofile-settings-submit’,
‘id’ => ‘submit’,
‘value’ => __( ‘Save Changes’, ‘buddypress’ ),
‘class’ => ‘auto’,
),

) );

if ( isset( $actions[ $action ] ) ) {
return $actions[ $action ];

}

TEMPLATE TAGS.PHP

function bp_nouveau_submit_button( $action ) {
$submit_data = bp_nouveau_get_submit_button( $action );
if ( empty( $submit_data[‘attributes’] ) || empty( $submit_data[‘nonce’] ) ) {
return;
}

if ( ! empty( $submit_data[‘before’] ) ) {

/**
* Fires before display of the submit button.
*
* This is a dynamic filter that is dependent on the “before” value provided by bp_nouveau_get_submit_button().
*
* @since 3.0.0
*/
do_action( $submit_data[‘before’] );
}

$submit_input = sprintf( ‘<input type=”submit” %s/>’,
bp_get_form_field_attributes( ‘submit’, $submit_data[‘attributes’] ) // Safe.
);

// Output the submit button.
