How to use login_form_top filter in WordPress

login_form_top Filter

The login_form_top filter evaluates just following the opening form tag element.

To use the login_form_top 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 at WePlugins 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_login_form_top_defaults which takes 2 parameters and we registered using add_filter. The first parameter login_form_top is the name of the hook, the second parameter weplugins_modify_login_form_top_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 the login_form_top filter.

Parameters

Below are the 2 parameters required to use this hook.

• $content: (string) Content to display. Default empty.
• $args: (array) Array of login form arguments.

Live Examples

Example 1: Basic Usage

Below is an example of how you can use this hook.

    function weplugins_modify_login_form_top_defaults($content, $args) {
        // Update the $content variable according to your website requirements and return this variable. You can modify the $content variable conditionally too if you want.
        return $content; 
    }
    // add the filter
    add_filter("login_form_top", "weplugins_modify_login_form_top_defaults", 10, 2);
    

Example 2: Removing the Hook

To remove a hook callback, use the example below.

    remove_filter("login_form_top", "weplugins_modify_login_form_top_defaults", 10, 2);
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Conditional Modification

This example shows how to conditionally modify the content.

    function weplugins_modify_login_form_top_conditional($content, $args) {
        if (some_condition()) {
            $content .= '<p>Additional content based on condition.</p>';
        }
        return $content;
    }
    add_filter("login_form_top", "weplugins_modify_login_form_top_conditional", 10, 2);
