This is What to Do When the Current Page Doesn't Work in wp_login_form
As a WordPress developer, you may have encountered a situation where the current page doesn't work in the wp_login_form()
function. This can be a frustrating problem, as it can prevent users from being redirected back to the page they were on before initiating the login process.
Fortunately, there's a solution to this issue, and it involves using the login_redirect
filter in WordPress. In this article, we'll walk you through the steps to fix the current page not working in wp_login_form()
.
Understanding the Problem
The wp_login_form()
function is used to display the login form on your WordPress site. By default, when a user successfully logs in, they are redirected to the WordPress admin dashboard or the homepage of your website.
However, in some cases, you may want to redirect the user back to the current page they were on before initiating the login process. This is where the problem can arise, as the wp_login_form()
function doesn't automatically handle this scenario.
The Solution: Using the login_redirect Filter
The solution to this problem lies in the login_redirect
filter in WordPress. This filter allows you to modify the URL that a user is redirected to after a successful login.
Here's how you can use the login_redirect
filter to redirect the user back to the current page:
function redirect_to_request( $redirect_to, $request, $user ){
return $request; // this is the URL the user is coming from
}
add_filter('login_redirect', 'redirect_to_request', 10, 3);
In this example, the redirect_to_request()
function is the callback function for the login_redirect
filter. The function takes three parameters:
$redirect_to
: The default redirect URL.
$request
: The URL the user is coming from (i.e., the current page).
$user
: The WP_User
object of the user who just logged in.
By returning the $request
parameter, the function tells WordPress to redirect the user back to the current page they were on before initiating the login process.
Real-World Examples
To better understand how this works, let's look at some real-world examples.
Example 1: Redirecting from the Login Page
Suppose you have a custom login page on your WordPress site, and you want to redirect the user back to the same page after a successful login. Here's how you can do it:
function redirect_to_request( $redirect_to, $request, $user ){
// Check if the user is coming from the login page
if ( strpos( $request, 'wp-login.php' ) !== false ) {
return $request;
}
// If not, return the default redirect URL
return $redirect_to;
}
add_filter('login_redirect', 'redirect_to_request', 10, 3);
In this example, the redirect_to_request()
function first checks if the user is coming from the login page (wp-login.php
). If they are, the function returns the $request
parameter, which is the URL of the login page. This will redirect the user back to the login page after a successful login.
If the user is not coming from the login page, the function returns the default redirect URL ($redirect_to
).
Example 2: Redirecting from a Custom Page
Now, let's say you have a custom page on your WordPress site that contains a login form. You want to redirect the user back to this custom page after a successful login. Here's how you can do it:
function redirect_to_request( $redirect_to, $request, $user ){
// Check if the user is coming from the custom page
if ( strpos( $request, 'custom-login-page' ) !== false ) {
return $request;
}
// If not, return the default redirect URL
return $redirect_to;
}
add_filter('login_redirect', 'redirect_to_request', 10, 3);
In this example, the redirect_to_request()
function checks if the user is coming from a page with the URL custom-login-page
. If they are, the function returns the $request
parameter, which is the URL of the custom login page. This will redirect the user back to the custom login page after a successful login.
If the user is not coming from the custom login page, the function returns the default redirect URL ($redirect_to
).

Example 3: Redirecting to a Specific Page
Sometimes, you may want to redirect the user to a specific page after a successful login, regardless of the page they were on before initiating the login process. Here's how you can do it:
function redirect_to_request( $redirect_to, $request, $user ){
// Redirect the user to a specific page
return 'https://example.com/dashboard';
}
add_filter('login_redirect', 'redirect_to_request', 10, 3);
In this example, the redirect_to_request()
function simply returns the URL of the page you want to redirect the user to, in this case, https://example.com/dashboard
. This will override the default redirect behavior and send the user to the specified page after a successful login.
Conclusion
The login_redirect
filter in WordPress is a powerful tool for customizing the behavior of the login process on your website. By using this filter, you can easily redirect users back to the current page they were on before initiating the login process, ensuring a seamless and intuitive user experience.
Remember, the key to making this work is to leverage the $request
parameter, which contains the URL the user is coming from. By returning this value in the login_redirect
filter, you can ensure that users are redirected back to the page they were on before logging in.
