Function and usage of force_ssl_admin() in wordpress


Answers ( 1 )


    The force_ssl_admin() function in WordPress is used to control whether Secure Sockets Layer (SSL) encryption is forced for the Administration Screens of a WordPress site. This function is particularly important for enhancing the security of your WordPress admin area.

    Function Signature:

    force_ssl_admin( string|bool $force = null ): bool


    • $force (string|bool) (optional): This parameter determines whether SSL should be forced in the admin screens. It can be a boolean value (true or false) or a string representation of these boolean values.
      • If true or 'true', SSL will be forced.
      • If false or 'false', SSL will not be forced.
      • The default value is null, which means the function will not change the current state but return whether SSL is currently being forced or not.

    Return Value:

    • The function returns a boolean value (true or false):
      • true: Indicates that SSL is forced for admin screens.
      • false: Indicates that SSL is not forced for admin screens.

    Sample Usage:

    1. To Check Current SSL State: You can call the function without any arguments to check whether SSL is currently being forced for the admin screens.

      $is_ssl_forced = force_ssl_admin();
    2. To Enable SSL: If you want to force SSL usage in the admin area, you would set $force to true.

    3. To Disable SSL: Conversely, if you need to ensure SSL is not forced in the admin area, set $force to false.


    Best Practices:

    • Security: It's recommended to force SSL in the admin area to secure data transmission, especially on live websites.
    • Testing: Be careful when changing SSL settings on live sites. Test on a staging or development environment first.
    • Compatibility Check: Ensure that your hosting environment fully supports SSL before enabling it.

    By using force_ssl_admin(), you can enhance the security of your WordPress admin area by ensuring that all data transmissions are encrypted, thus protecting sensitive information from being intercepted.
