Function and usage of login_header() in wordpress


Answers ( 1 )


    The login_header() function in WordPress is used to output the header of the login page. This function is part of WordPress's login system and plays a critical role in customizing the appearance and behavior of the login page. Below is a detailed explanation of the function and its parameters:


    • Name: login_header()
    • Purpose: To output the header of the WordPress login page.


    1. $title (string, optional):

      • Purpose: Specifies the title of the WordPress login page. This title is displayed in the <title> element of the HTML header.
      • Default Value: 'Log In'. If not specified, "Log In" is used as the default title.
    2. $message (string, optional):

      • Purpose: Allows a custom message to be displayed in the header of the login page. This can be useful for showing informational messages or instructions to the users.
      • Default Value: An empty string (''). If no message is provided, no additional message is displayed.
    3. $wp_error (WP_Error, optional):

      • Purpose: Used to pass error messages to the login page. This is particularly useful for displaying login errors (like incorrect username or password) or other authentication-related errors.
      • Default Value: null. By default, a new instance of WP_Error is used if no error object is passed.

    Sample Usage:

    Here's an example of how you might use login_header() in a custom WordPress login page:

    // Custom login page header
    // Title for the login page
    $login_title = 'Welcome to My WordPress Site';
    // Custom message for users
    $login_message = 'Please enter your credentials to proceed.';
    // Assuming $login_error is a WP_Error object containing login errors
    $login_error = new WP_Error();
    // Output the login header
    login_header($login_title, $login_message, $login_error);

    In this example, the login_header() function is called with a custom title, a message for the users, and a WP_Error object. This setup allows for a more personalized login experience, providing clear instructions and displaying any relevant errors to the users.


    • login_header() is typically used in conjunction with other functions to create a complete custom login page.
    • It's important to ensure that customizations to the login page comply with WordPress standards and best practices, especially in terms of security and user experience.
