Read the docs re how to use apply_filters.
Try:
add_filter('bp_members_signup_error_message', 'function_voornaam');
Yes, I have done that. So the complete code is then like this:
add_filter('bp_members_signup_error_message', 'function_voornaam');
function function_voornaam($value, $fieldname)
{
if ($fieldname == 'field_1') {
return '<style>{font-family:bold}</style> you have to enter name.';
}
}
But then I get this error:
atal error: Uncaught ArgumentCountError: Too few arguments to function function_voornaam(), 1 passed in E:\Xampp\htdocs\wordpress\wp-includes\class-wp-hook.php on line 303 and exactly 2 expected in E:\Xampp\htdocs\wordpress\wp-content\themes\buddyboss-theme-child\functions.php:49 Stack trace: #0 E:\Xampp\htdocs\wordpress\wp-includes\class-wp-hook.php(303): function_voornaam('show_messagge') #1 E:\Xampp\htdocs\wordpress\wp-includes\plugin.php(189): WP_Hook->apply_filters('show_messagge', Array) #2 E:\Xampp\htdocs\wordpress\wp-content\themes\buddyboss-theme-child\functions.php(68): apply_filters('bp_members_sign...', 'show_messagge') #3 E:\Xampp\htdocs\wordpress\wp-settings.php(546): include('E:\\Xampp\\htdocs...') #4 E:\Xampp\htdocs\wordpress\wp-config.php(97): require_once('E:\\Xampp\\htdocs...') #5 E:\Xampp\htdocs\wordpress\wp-load.php(50): require_once('E:\\Xampp\\htdocs...') #6 E:\Xampp\htdocs\wordpress\wp-blog-header.php(13): require_once('E:\\Xampp\\htdocs...') #7 E:\Xampp\htdocs\wordpress\index.php(17): require('E:\\Xampp\\htdocs...') #8 {main} thrown in E:\Xampp\htdocs\wordpress\wp-content\themes\buddyboss-theme-child\functions.php on line 49
But if I do this:
apply_filters('bp_members_signup_error_message', 'function_voornaam()');
function function_voornaam($value, $fieldname)
{
if ($fieldname == 'field_1') {
return '<style>{font-family:bold}</style> wrong name';
}
}
I don’t get errors. But also the text is not changed. It is still shown:
This is a required field.
And I found this documentation:
bp_members_signup_error_message
Try this:
add_filter( 'bp_members_signup_error_message', 'function_voornaam', 10, 2 );
function function_voornaam( $value, $fieldname ) {
if ( $fieldname == 'field_1' ) {
return '<style>{font-family:bold}</style> you have to enter name.';
}
return $value;
}
thank you. But then I get this error:
Fatal error: Uncaught ArgumentCountError: Too few arguments to function function_voornaam(), 1 passed in E:\Xampp\htdocs\wordpress\wp-includes\class-wp-hook.php on line 303 and exactly 2 expected in E:\Xampp\htdocs\wordpress\wp-content\themes\buddyboss-theme-child\functions.php:48 Stack trace: #0 E:\Xampp\htdocs\wordpress\wp-includes\class-wp-hook.php(303): function_voornaam('show_messagge') #1 E:\Xampp\htdocs\wordpress\wp-includes\plugin.php(189): WP_Hook->apply_filters('show_messagge', Array) #2 E:\Xampp\htdocs\wordpress\wp-content\themes\buddyboss-theme-child\functions.php(66): apply_filters('bp_members_sign...', 'show_messagge') #3 E:\Xampp\htdocs\wordpress\wp-settings.php(546): include('E:\\Xampp\\htdocs...') #4 E:\Xampp\htdocs\wordpress\wp-config.php(97): require_once('E:\\Xampp\\htdocs...') #5 E:\Xampp\htdocs\wordpress\wp-load.php(50): require_once('E:\\Xampp\\htdocs...') #6 E:\Xampp\htdocs\wordpress\wp-blog-header.php(13): require_once('E:\\Xampp\\htdocs...') #7 E:\Xampp\htdocs\wordpress\index.php(17): require('E:\\Xampp\\htdocs...') #8 {main} thrown in E:\Xampp\htdocs\wordpress\wp-content\themes\buddyboss-theme-child\functions.php on line 48
You need to look at themes\buddyboss-theme-child\functions.php : Line 48 to see what arguments are passed in the filter hook and then change your function to include all those arguments.
And the ‘2’ in
add_filter( 'bp_members_signup_error_message', 'function_voornaam', 10, 2 );
needs to equal the number of arguments passed in the filter hook.
that is my own function: line 48.
and this is the doucumentation from buddyboss:
apply_filters( 'bp_members_signup_error_message', string $value, string $fieldname )
So I pass two arguments.
So how can I improve this?
There is already a filter with that name:
apply_filters( 'bp_members_signup_error_message', '<div class="error">' . $error_message . '</div>' );
It passes only one argument. You need to write a custom filter hook with a different name.
also – these are the forums for BuddyPress.
Please contact BuddyBoss for questions specific to their codebase.
