Change validation criteria when creating new blogs on wp-signup.php

    I’m about to create a plugin that changes the validation criterias in the wp-signup.php

    My approach is to create a plugin that hooks a filter to the wpmu_validate_blog_signup hook and modifies the WP_Error object that comes from the wpmu_validate_blog_signup function.

    Something like this:

    function filter_new_signup_criterias($content) {
  // Check if the error exist
  // If the error exist, remove it and revalidate with 2 characters.
  // Add a new error if the current blogname is shorter than 2 characters.
}

add_filter('wpmu_validate_blog_signup','filter_new_signup_criterias');

    What I can’t understand (maybe it’s not possible?) is how to remove an existing error from the WP_Error object?

    In my case I would like to remove the error with error code: “blogname” and error message: “Site name must be at least 4 characters” and change the criteria so that it can take blog names with only 2 characters.

    What I did in my case was to sort out all outer possibilities of errors until the “Site name must be at least 4 characters” was the only one left. In that case I:

    1. Cleaned the given WP_Error object.

    2. Revalidated the blogname with:

    if (onlyOneBlogNameError($errors)) { // If there is only one blogname validation error.
  // Check if the string length is < 4
  if (toShortBlognameForWP($blogname)) {

    // Create a new error object.
    $new_errors = new WP_Error;

    // Check if string length is < 2
    if (toShortBlognameForMyPlugin($blogname)) {

      // add blogname error to new error object.
      $new_errors->add( 'blogname', __( "Site name must be at least 2 characters", "new-signup-form" ) );
    }

  // add the new error object to the returning result.
  $prev_results['errors'] = $new_errors;
}

    3. …and then return the result.
