Thanks Paul!

$meta[‘field_1’] definitely looks like something to try, although I still totally don’t “get” serialized PHP arrays.

I was also wondering if I could just bp_user_fullname() at this point, before activation.

Trying both now…

EDIT:

function synchro_wp_usermeta($user_id, $meta) {

global $bp, $wpdb;



$fullname = $meta['field_1'];

$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



update_usermeta( $bp->loggedin_user->id, 'nickname', $fullname );

update_usermeta( $bp->loggedin_user->id, 'first_name', $firstname );

update_usermeta( $bp->loggedin_user->id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $bp->loggedin_user->id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $bp->loggedin_user->id ), $bp->loggedin_user->id ) );

}

add_action( 'wpmu_activate_user',  'synchro_wp_usermeta' );



?>

Registration process works fine, but I with this error in the screen on activation:

Warning: Missing argument 2 for synchro_wp_usermeta() in /serverpath/wp-content/mu-plugins/bp-custom.php on line 187

I had taken $password out. Thought I didn’t need it. Will try again with it added back in….

EDIT2: Adding $password only gives me a second error:

Warning: Missing argument 2 for synchro_wp_usermeta() in /serverpath/wp-content/mu-plugins/bp-custom.php on line 187

Warning: Missing argument 3 for synchro_wp_usermeta() in /serverpath/wp-content/mu-plugins/bp-custom.php on line 187

Can I just take $user_id out? Is all the information I need already in that wpmu_activate_user action?

I’ll try that next, after deleting test users. Running out of email addresses…

You’ll need to have all three arguments, even if you don’t want to use them all. You can miss out ones AFTER the one you want, but you can’t miss anything out before the one you wish to use.

Are you sure about that? With the three arguments I get two ‘Missing argument’ error messages. With only $meta there are no errors – although it doesn’t do anything either…

EDIT: Tried the code below. Again one ‘Missing argument’ error. Registration goes through as normal, but nothing in wp_usermeta:

function synchro_wp_usermeta($user_id, $meta) {

global $bp, $wpdb;



$field_ids = $meta['xprofile_field_ids'];

$field_ids = explode( ',', $field_ids );



// Loop through each bit of profile data and save it to profile.

for ( $i = 0; $i < count($field_ids); $i++ ) {

if ( empty( $field_ids[$i] ) ) continue;



$field_value = $meta["field_{$field_ids[$i]}"];

}



$fullname = $meta['field_1'];

$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



update_usermeta( $bp->loggedin_user->id, 'nickname', $fullname );

update_usermeta( $bp->loggedin_user->id, 'first_name', $firstname );

update_usermeta( $bp->loggedin_user->id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $bp->loggedin_user->id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $bp->loggedin_user->id ), $bp->loggedin_user->id ) );

}

add_action( 'wpmu_activate_user',  'synchro_wp_usermeta' );

The last attempt in the previous post does not work. No error messages, registration goes through as normal, but nothing in wp_usermeta.

This also has no effect:

function synchro_wp_usermeta() {

global $bp_user_signup_meta, $bp, $wpdb;



$fields = BP_XProfile_Field::get_signup_fields();



if ( $fields ) {

foreach ( $fields as $field ) {



$fullname = $_POST['field_1'];

}

}



$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



update_usermeta( $bp->loggedin_user->id, 'nickname', $fullname );

update_usermeta( $bp->loggedin_user->id, 'first_name', $firstname );

update_usermeta( $bp->loggedin_user->id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $bp->loggedin_user->id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $bp->loggedin_user->id ), $bp->loggedin_user->id ) );

}

add_action( 'user_register', 'synchro_wp_usermeta' );

Please, I need feedback to finish this function/plugin. A real coder can spot the problem probably immediately. Please point it out, don’t leave me hanging.

Thanks for the additional clues DJPaul!

In the latest attempt I was going back to my first approach, trying to catch the input straight from the form, so that has to run on initial user registration, not on activation.

Or is user_register not used in Buddypress at all? Is there a wpmu or bp equivalent I could try? Should I use wpmu_create_user? According to this blog post:

the do_action for wpmu_new_user is directly at the bottom of wpmu_create_user in the wp-includes/wpmu-functions.php the wpmu_create_user gets sent the username password and email and checks if the username or email exists, if not create the new user in the database and assign a user_id to the return, also assigning capabilities and level … this happens on *all* levels of registration and is the perfect hook point to add them into the database

the do_action do_action( ‘wpmu_new_user’, $user_id ); so you get the immediate user_id soon as it’s created which you can use in your table

Apparantly this is like a flowchart of registration events in wpmu (wp-includes/wpmu-default-filters.php):

add_filter ( 'wpmu_validate_user_signup', 'signup_nonce_check' );

add_action ( 'init', 'maybe_add_existing_user_to_blog' );

add_filter ( 'xmlrpc_methods', 'attach_wpmu_xmlrpc' );

add_filter ( 'wp_authenticate_user', 'wordpressmu_authenticate_siteadmin', 10, 2 );

add_action ( 'wpmu_new_user', 'newuser_notify_siteadmin' );

add_action ( 'wpmu_activate_user', 'add_new_user_to_blog', 10, 3 );

add_action ( 'sanitize_user', 'strtolower_usernames', 10, 3 );

Should I focus on these wpmu action hooks instead of regular wp hook? Does bp have a list like this somewhere?

I couldn’t figure out how to serialize that $meta data and extract the fullname from it, so I abandoned the approach hooking into wpmu_activate_user for now. Also when I put in the $user_id and $password arguments I got the error messages about missing arguments. wtf?!

I think this bit of code grabs the input from the registration form:

$fields = BP_XProfile_Field::get_signup_fields();



if ( $fields ) {

foreach ( $fields as $field ) {



$value = $_POST['field_' . $field->id];

fullname is the input from field_1, but I don’t know how to finish the php to get to $fullname = … . The two latest attempts above did not work.

I have to give up for now. Deadline at my day job coming up…

You mean the 3 at the end of that line would fix that? I’ll try that next with a previous version of my code.

Just for the record, this attempt again didn’t work. No errors, but nothing in wp_usermeta either:

function synchro_wp_usermeta() {

global $bp_user_signup_meta, $bp, $wpdb;



$fields = BP_XProfile_Field::get_signup_fields();



if ( $fields ) {

foreach ( $fields as $field ) {



$value = $_POST['field_' . $field->id];



}

}



$fullname = $value['field_1'];

$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



update_usermeta( $bp->loggedin_user->id, 'nickname', $fullname );

update_usermeta( $bp->loggedin_user->id, 'first_name', $firstname );

update_usermeta( $bp->loggedin_user->id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $bp->loggedin_user->id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $bp->loggedin_user->id ), $bp->loggedin_user->id ) );

}

add_action( 'wpmu_new_user', 'synchro_wp_usermeta' );

This fixes the missing arguments errors, but still nothing in wp_usermeta. I’ll need to figure out how to serialize (?) $meta and extract $fullname from it:

function synchro_wp_usermeta($user_id, $password, $meta) {

global $bp, $wpdb;



$fullname = $meta['field_1'];

$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



update_usermeta( $bp->loggedin_user->id, 'nickname', $fullname );

update_usermeta( $bp->loggedin_user->id, 'first_name', $firstname );

update_usermeta( $bp->loggedin_user->id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $bp->loggedin_user->id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $bp->loggedin_user->id ), $bp->loggedin_user->id ) );

}

add_action( 'wpmu_activate_user', 'synchro_wp_usermeta', 10, 3);

This version also doesn’t work. No errors, registration goes through as normal, but still no first_name and last_name in wp_usermeta:

function synchro_wp_usermeta($user_id, $password, $meta) {

global $bp, $wpdb;



$field_ids = $meta['xprofile_field_ids'];

$field_ids = explode( ',', $field_ids );



// Loop through each bit of profile data and save it to profile.

for ( $i = 0; $i < count($field_ids); $i++ ) {

if ( empty( $field_ids[$i] ) ) continue;



$field_value = $meta["field_{$field_ids[$i]}"];



$field 				 = new BP_XProfile_ProfileData();

$field->user_id      = $user_id;

$field->value        = $field_value;

$field->field_id     = $field_ids[$i];

$field->last_updated = time();



$field->save();

}



$fullname = $field_value['field_1'];

$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



update_usermeta( $bp->loggedin_user->id, 'nickname', $fullname );

update_usermeta( $bp->loggedin_user->id, 'first_name', $firstname );

update_usermeta( $bp->loggedin_user->id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $bp->loggedin_user->id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $bp->loggedin_user->id ), $bp->loggedin_user->id ) );

}

add_action( 'wpmu_activate_user', 'synchro_wp_usermeta', 10, 3);

Again, any suggestions that can move this along are very much appreciated.

The problem really is how to extract the fullname data from the meta field in wp_signups. Can I do something similar to this:

xprofile_get_field_data( BP_XPROFILE_FULLNAME_FIELD_NAME, $bp->loggedin_user->id );

Is there a wp_signups_get_field_data I can tap into?

Or some type of database query?:

$wpdb->read( $wpdb->signups, array('???' => 1), array('??' => $key) );

When I do this:

$fullname = $wpdb->get_var("SELECT meta FROM $wpdb->signups");

echo $fullname;

I get the serialized content of the first meta field in wp_signups:

a:8:{s:7:"field_1";s:13:"Julius Caesar";s:18:"xprofile_field_ids";s:2:"1,";s:20:"avatar_image_resized";s:84:"/serverpath/wp-content/blogs.dir/1/files/avatars/0/caesar.jpg";s:21:"avatar_image_original";s:84:"/serverpath/wp-content/blogs.dir/1/files/avatars/0/caesar.jpg";s:6:"public";s:1:"1";s:7:"lang_id";i:1;s:8:"blogname";s:9:"theempire";s:10:"blog_title";s:16:"The Roman Empire";}

The function inserted this crap also into the wp_usermeta fields. Success! (Sort of…)

The bit of data I need is the fullname, the second bit, in this case ‘Julius Caesar’. I’d need the second bit of data from the user with the activation key.

How would I add that to the query?

I’ll first try this:

$fullname = $wpdb->get_var("SELECT meta FROM $wpdb->signups WHERE activation_key = %s", $key);

echo $fullname;

Nothing…

I probably had to add $key as an argument. Trying again after some food…

With this:

$array = $wpdb->get_var("SELECT meta FROM $wpdb->signups");

$my_vars = unserialize($array);



foreach($my_vars as $name => $value)

{

print $name . ' has the value: ' . $value . '<br />';

}

I get this:

field_1 has the value: Julius Caesar

xprofile_field_ids has the value: 1,

avatar_image_resized has the value: /serverpath/wp-content/blogs.dir/1/files/avatars/0/caesar.jpg

avatar_image_original has the value: /serverpath/wp-content/blogs.dir/1/files/avatars/0/caesar.jpg

public has the value: 1

lang_id has the value: 1

blogname has the value: theempire

blog_title has the value: The Roman Empire

So how do I get just that ‘Julius Caesar’ value?

I’ve tried adding this and many variations. Nothing works:

$value['field_1'] = $fullname;



echo $fullname;

This should work:

function synchro_wp_usermeta( $user_id, $password, $meta ) {

global $bp, $wpdb;



$fullname = $meta[field_1];



echo $fullname;



$space = strpos( $fullname, ' ' );



if ( false === $space ) {

$firstname = $fullname;

$lastname = '';

} else {

$firstname = substr( $fullname, 0, $space );

$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );

}



update_usermeta( $bp->loggedin_user->id, 'nickname', $fullname );

update_usermeta( $bp->loggedin_user->id, 'first_name', $firstname );

update_usermeta( $bp->loggedin_user->id, 'last_name', $lastname );



$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $bp->loggedin_user->id ) );

$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $bp->loggedin_user->id ), $bp->loggedin_user->id ) );

}

add_action( 'wpmu_activate_user', 'synchro_wp_usermeta', 10, 3);

BTW, I see Lance Willet here uses $userid with wpmu_activate_user, instead of $key.

Does $bp->loggedin_user->id even work on activation? Shouldn’t everything be based on the activation key?
