BuddyPress.org

Have you tried using a standard theme like WP 2015?

Are you running any membership plugins or code that affects profile fields?

You may want to wipe the installation, including the database, and start over.

@insearchofasolution Just thought I would chime in on this.

You would be able to do this but it depends on the approach you take, You could use buddypress for the social network side of things for the messaging between users etc and profile pages/groups etc whilst building a custom user interface for most of the other options you mentioned and tie them together for each user.

Its good you are clear about what you are exactly wanting to build and its all down to research, You can most definitely create separate vendor pages and account pages using custom post types and fields and creating templates for these pages etc.

If you don’t know how to do all of this you may struggle though, unless a specific plugin meets your requirements, I myself have been using an amazing suite of plugins over the past year or so that will help you do a lot of this yourself , they are brilliant for creating complex websites and layouts without having to write everything from scratch. You will have to have knowledge of html and css etc at the very least to use them efficiently though, they do come at a cost and you are looking at $300 for the complete set, these plugins are a little more advanced than other plugins to use as they are developer orientated and can be overwhelming at first if you are new to them, but if you stick with them you will start to realize the doors these plugins can open for you on wordpress and can help make your workflow loads faster and make your project come to life. do a search for TOOLSET PLUGINS by wp-types.

I hope this helps a little bit, creating a complex website as you mentioned above will take patience and time if you are new to doing it, I am in the middle of a few complex builds myself and to be honest with you I now pre-fare to use these plugins for most of my projects now as I can easily create any type of custom post with custom fields and display them via content templates without having to create the templates from scratch on each project.

The best thing about the custom fields you can create with these plugins is that you can create user specific fields and control access to everything with the access plugin, giving you full control over everything and you can create quite complex membership sites yourself.

Most of bp files are in php, so i can’t answer for YOUR php file.

I you modify the register page, where xprofile fields are showing at first, the template file i’m talking about is in bp-templates/bp-legacy/buddypress/members/register.php.

If you don’t know about template overload, read here first.

Or if you use a custom function to fire your work via an action hook, perhaps you could try to use bp-custom.php

That’s unfortunately what i expected… GF is a third party premium plugin for which nobody can help you here, except if he/she use that plugin.

If you read here, it’s somehow explained in details.

What you already used (gform_field_value_linkuser), linkuser is a GF field name. If i’m right, see the advanced tab of that field and complete the name parameter.

Here a snippet which let you see how to link a username to his profile, when you’re outside of the member_loop. It will output the current user name on the site wide activity header. For test only.

Note that it use BuddyPress default Name field and that it comes from a BP form. As you use GF, you certainly need to find how to grab properly a GF field value.

Function goes to bp-cutom, may also work in theme’s functions.php

function bpfr_my_profile_link_on_SWA_header () {	
	$user_id = get_current_user_id();
	$profile_url = bp_loggedin_user_domain();

	if( !is_user_logged_in() ) {
		return;
	}

	echo '<br>Test userlink:&nbsp;'; 

	if ( !$data = bp_get_profile_field_data( 'field=Name' ) ) : 

		echo xprofile_get_field_data( 'Name', bp_get_member_user_id() ) .'<a href="'. $profile_url .'">'. bp_core_get_username( $user_id ).'</a><br>';

	endif;		

}
add_action( 'bp_activity_type_tabs', 'bpfr_my_profile_link_on_SWA_header' ); 

Sorry, I can’t help you more.

Perhaps this can help you to go further.

For point 2, maybe this snippet can do the job. Give it a try ! Add it to bp-custom.php

function custom_display_xprofile_fields() {

// single field item
if ( $data = bp_get_profile_field_data( 'field=Industry' ) ) : // change field name to yours
	echo '<div class="industry">'. xprofile_get_field_data( 'Industry', bp_displayed_user_id() ) .'</div>';
endif;
}
add_action( 'bp_after_profile_loop_content' , 'custom_display_xprofile_fields' );

dont think so…just export the 4 xprofile fields rows form the db via phpmyadmin and import them back

any profile fields you add to the first field group get added to the registration form.
