} add_action('admin_init', 'register_and_build_fields');

function register_and_build_fields() {

register_setting('theme_options', 'theme_options', 'validate_setting');

add_settings_section('homepage_settings', 'Homepage Settings', 'section_homepage', __FILE__);

add_settings_section('footer_settings', 'Footer Settings', 'section_footer', __FILE__);

function section_homepage() {

}

function section_footer() {

}

add_settings_field('button1text', 'Button 1 Text', 'button1text_setting', __FILE__, 'homepage_settings');

}

function validate_setting($theme_options) {

return $theme_options;

}

function button1text_setting() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[button1text_setting]" value="{$options[" />";

}

function button1link_setting() {

echo "<input type="text" name="theme_options[button1link_setting]" value="{$options[" />";

}

function button2text_setting() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[button2text_setting]" value="{$options[" />";

}

function button2link_setting() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[button2link_setting]" value="{$options[" />";

}

function button3text_setting() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[button3text_setting]" value="{$options[" />";

}

function button3link_setting() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[button3link_setting]" value="{$options[" />";

}

function phonenumber() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[phonenumber]" value="{$options[" />";

}

function facebookurl() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[facebookurl]" value="{$options[" />";

}

function googleurl() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[googleurl]" value="{$options[" />";

}

function twitterurl() {

$options = get_option('theme_options');

echo "<input type="text" name="theme_options[twitterurl]" value="{$options[" />";

}

add_action('admin_menu', 'theme_options_page');

function theme_options_page() {

add_menu_page('Theme Settings', 'Theme Settings', 'administrator', __FILE__, 'build_options_page', '', '62.2');

}

Then we create a variable with all our settings so we can use it in the template.

<?php $options = get_option('theme_options'); ?>

Then we can use some of the options like this:

<a href="<?php echo $options['button1link_setting']; ?>"><?php echo $options['button1text_setting']; ?></a>
