Here, so that no one may accuse me of any kind of unwillingness to contribute and help fix a plugin to help those who don’t know or aren’t comfortable with messing with the code, here are the modifications to add a sub-menu to the admin panel giving people an option to give a promo back or not with the added benefit of a div class for styling options. If you want, you can even use it to put different messages for the user to see or, if you’re comfortable with coding, you can extend the plugin and easily make changes to those additional options right in the admin panel.
Add the following right before the ?> at the bottom of captcha-free.php…
// Hook for adding admin menus
add_action('admin_menu', 'captcha_free_promo');
// action function for above hook
function captcha_free_promo() {
// Add a new submenu under Settings:
add_options_page(__('WP Captcha-Free','menu-captcha-free'), __('WP Captcha-Free','menu-captcha-free'), 'manage_options', 'captcha-free-settings', 'captcha_free_settings_page');
}
// captcha_free_settings_page() displays the page content for the settings submenu
function captcha_free_settings_page() {
//must check that the user has the required capability
if (!current_user_can('manage_options'))
{
wp_die( __('You do not have sufficient permissions to access this page.') );
}
// variables for the field and option names
$opt_name = 'captcha-free-promo';
$hidden_field_name = 'captcha_free_submit_hidden';
$data_field_name = 'captcha-free-promo';
// Read in existing option value from database
$opt_val = get_option( $opt_name );
// See if the user has posted us some information
// If they did, this hidden field will be set to 'Y'
if( isset($_POST[ $hidden_field_name ]) && $_POST[ $hidden_field_name ] == 'Y' ) {
// Read their posted value
$opt_val = $_POST[ $data_field_name ];
// Save the posted value in the database
update_option( $opt_name, $opt_val );
// Put an settings updated message on the screen
?>
<div class="updated"><p><strong><?php _e('settings saved.', 'menu-captcha-free' ); ?></strong></p></div>
<?php
}
// Now display the settings editing screen
echo '<div class="wrap">';
// header
echo "<h2>" . __( 'WP Captcha-Free Promo Notice Setting', 'menu-captcha-free' ) . "</h2>";
// settings form
?>
<form name="captcha-free-promo-settings" method="post" action="">
<input type="hidden" name="<?php echo $hidden_field_name; ?>" value="Y">
<p><?php _e("Promo Message:", 'menu-captcha-free' ); ?>
<input type="text" name="<?php echo $data_field_name; ?>" value="<?php echo $opt_val; ?>" size="50" />
</p>
<p>The original message: <a href="https://wordpresssupplies.com/wordpress-plugins/captcha-free/">Spam protection by WP Captcha-Free</a></small></p>
<hr />
<p class="submit">
<input type="submit" name="Submit" class="button-primary" value="<?php esc_attr_e('Save Changes') ?>" />
</p>
</form>
</div>
<?php
}
Then, find the following line…
<p><small><noscript><strong>Please note:</strong> JavaScript is required to post comments.</noscript> <a href="https://wordpresssupplies.com/wordpress-plugins/captcha-free/">Spam protection by WP Captcha-Free</a></small></p>
and change it to this…
<p><small><noscript><strong>Please note:</strong> JavaScript is required to post comments.</noscript><div class="captcha-free-promo"><?php print get_option('captcha-free-promo'); ?></div></p>
