submit_button

Function Name: submit_button

The submit_button() function is a WordPress core function that allows developers to create a submit button for forms in the WordPress admin panel. This function is particularly useful for plugin and theme developers who want to create custom forms and settings pages.

The submit_button() function generates a button with the label "Save Changes" by default, but developers can change the label by passing an argument to the function. The function also includes a hidden input field called "_wpnonce" that helps protect against CSRF attacks.

Example usage code:

<?php
// Create a custom form with a submit button
function my_custom_form() {
  ?>
  <form method="POST" action="">
    <label for="name">Name:</label>
    <input type="text" name="name" id="name">
    <?php
      // Add the submit button
      submit_button('Save Name');
    ?>
  </form>
  <?php
}

// Display the custom form
add_action('admin_menu', function() {
  add_menu_page('My Custom Form', 'My Custom Form', 'manage_options', 'my-custom-form', 'my_custom_form');
});

In this example, we create a custom form with a single input field for the user’s name and a submit button labeled "Save Name". We use the submit_button() function to generate the submit button. When the user submits the form, the data is sent to the URL specified in the form’s "action" attribute.
