The filtered WP_Error object may, for example, contain errors for an invalid username or email address. A WP_Error object should always be returned, but may or may not contain errors.
To use lostpassword_errors filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.
We always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.
In the below live example, we have defined a function weplugins_modify_lostpassword_errors_defaults which takes 2 parameters and we registered using add_filter. The first parameter lostpassword_errors is the name of the hook, The second parameter weplugins_modify_lostpassword_errors_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.
Sometimes, you have to remove a registered hook so you can use remove_filter to remove lostpassword_errors filter.
Parameters
Below are the 2 parameters required to use this hook.
Live Example 1: Basic Usage
Below is an example of how you can use this hook.
function weplugins_modify_lostpassword_errors_defaults($errors, $user_data) {
// Update the $errors variable according to your website requirements and return this variable. You can modify the $errors variable conditionally too if you want.
return $errors;
}
// add the filter
add_filter( "lostpassword_errors", "weplugins_modify_lostpassword_errors_defaults", 10, 2 );
Live Example 2: Removing a Hook
To remove a hook callback, use the example below.
remove_filter( "lostpassword_errors", "weplugins_modify_lostpassword_errors_defaults", 10, 2 );
Please make sure to provide the same callback function name, priority and number of arguments while removing the hook callback.
Live Example 3: Conditional Modification
Here’s how you can modify errors conditionally based on user data.
function weplugins_conditional_lostpassword_errors($errors, $user_data) {
if (!$user_data) {
$errors->add('no_user', 'User does not exist.');
}
return $errors;
}
add_filter("lostpassword_errors", "weplugins_conditional_lostpassword_errors", 10, 2);
