Naomi requested the  following code from my WordPress AI Code Generator.

Form telling customers to sign up to my mailing list

The robot generated the following code:

In WordPress, we generally use plugins or widgets to perform these actions. But in case if you want a custom implementation, you can add a function in the theme's `functions.php` file to get the form's HTML work done.

“`php
function nm_Form_mailinglist_signup() {
ob_start();
?>
<div id="nm-mailinglist-form">
<form action="" method="post">
<p>
<label for="nm-email">Your Email:</label><br/>
<input type="email" id="nm-email" name="nm-email" required>
</p>
<p>
<input type="submit" id="nm-submit" name="nm-submit" value="Sign Up">
</p>
</form>
</div>
<?php
return ob_get_clean();
}
add_shortcode('nm_mailinglist_signup', 'nm_Form_mailinglist_signup');
“`

Now, you can use the `[nm_mailinglist_signup]` shortcode to display the signup form anywhere on your website.

However, this code only displays the form. To make it functional, you will need to handle the form submission and send the data to your mailing list API.

Remember to add input validation and sanitization to ensure that only valid and safe data gets through.

_Note: WordPress does not recommend making direct changes to the theme's `functions.php` file. Instead, you should use a child theme or a functionality plugin to avoid losing your modifications when you update the theme._
