Introduction to Hook login_form_top in WordPress
Let's assume you are currently working on a WordPress website and are in the process of developing custom input fields. One of the notable and important features of WordPress is hooks, which allow us to add our own code in specific spots of the WordPress code, enabling us to perform our custom tasks before rendering the input form. The hook login_form_top is one of these points that allows us to run our custom code before the input form is displayed.
Using the hook login_form_top gives you the ability to implement specific features such as displaying messages, adding additional fields, or creating other modifications in the input form. For example, you may want to add a welcome message for new users. By using this hook, your job becomes simpler.
In this section, we will discuss how to use this hook and how to code for it. You will need to place your code in the functions.php file of your theme or a custom plugin. Do not forget that you always need to back up your site before making significant changes.
Now let's take a look at the code that can assist us in implementing this hook. This code simply adds a message to the input form.
function my_custom_login_message() {
echo 'Welcome to our site!
';
}
add_action('login_form_top', 'my_custom_login_message');
Code Explanation
Let's analyze this code line by line:
function my_custom_login_message() {This line defines a function named my_custom_login_message, which outputs the welcome message.
echo 'Welcome to our site!
'; In this line, the welcome message is output with a green color.
} This line closes the function and specifies all its functionalities.
add_action('login_form_top', 'my_custom_login_message'); In this line, we specify that the login_form_top hook is linked to our function so that it executes when the input form is displayed.
