I want to change the “registration successfully” message

Hello, @anaskambal

Please use the following snippet in your child theme’s functions.php to show a message after a user registers to your liking

add_filter( 'wp_login_errors', 'filter_wp_login_errors', 10, 2 );

function filter_wp_login_errors( $errors, $redirect_to ) {

  // make the changes to register message
  $errors->add( 'registered', sprintf( __( '<br> Please check your Spam box if email is 
  not to be found in inbox.' ), wp_login_url() ), 'message' );
  return $errors;
}

Here is how your message will look like https://d.pr/i/bslMB8

Thank you.

@abdulwahab610 Thank you very much.

Your code appends a message to the register message. Is there a way I can change the default registration message altogether

And another problem is new message is appearing on the login page too.

Hey, @sumon1068

You can use the following snippet to remove the default error message and add new.

* Change the Register password fields not match error message
* @param WP_Error $wp_error The WP_Error object.
* @param string Redirect destination URL.
*
* @return WP_Error $wp_error The WP_Error object.
*/
add_filter( 'registration_errors', 'filter_wp_login_errors', 10, 2 );

function filter_wp_login_errors( $errors, $redirect_to ) {

 if( strpos($_SERVER['REQUEST_URI'],'action=register') !== false ) {
  $errors->remove( 'password_mismatch');
  $errors->add( 'password_mismatch', sprintf( __( 'Custom Mismatch Error message.' ), 
  wp_login_url() ) );
  return $errors;
 } else{
  return $errors;
 }
}

Let me know is it work for you or not.
Thank you.

Unfortunately your code just shows error message. Even it doesn’t let users register.

Anyway, I am using redirection method described here.

Thank you.

Hi @sumon1068,
Please use the following snippet in your child theme’s functions.php to show a message after a user registers to your liking.
Here is the output of the code => https://d.pr/i/WjmwKW

/**
 * Change the Register Success message 
 * @param WP_Error	$wp_error The WP_Error object.
 * @param string		Redirect destination URL.
 * 
 * @return WP_Error	$wp_error The WP_Error object.
 */
add_filter( 'wp_login_errors', 'filter_wp_login_errors', 10, 2 );

function filter_wp_login_errors( $errors, $redirect_to ) {
	//Run Only if user registration is a success
	if( strpos($_SERVER['REQUEST_URI'],'checkemail=registered') !== false ) {

		//Remove the existing Register success message
		$errors->remove( 'registered');

		// make the changes to register message
		$errors->add( 'registered', sprintf( __( 'Please check your Spam box if email is 
		not to be found in inbox.' ), wp_login_url( ) ), 'message' );

		return $errors;

	} else{
		//Return the other message and errors
		return $errors;
	}
}

Thank you very much @wparslan

This works great.
