如何输出单选按钮变量前端 - wordpress

Question

I am working on my themes options panel (in administration/backend) and I am struggling with radio buttons.

I followed this tutorial: https://github.com/cferdinandi/wp-theme-options/ for creating radio buttons. They are now in themes options but I don't know how to make output of it into themes frontend.

I want just to try to echo the value of radio buttons form but I don't know the name of the variable in which it is saved.

Normally in php I would do it like so: if ($_POST['NAME']=="VALUE1") { echo "Some text here"; }

With text fields I use just it: <?php echo $options['csscolor_setting']; ?> (in for example header.php)
And in functions.php i have:

function csscolor_setting() {

    $options = get_option('theme_options');  echo "<input name='theme_options[csscolor_setting]' type='text' value='{$options['csscolor_setting']}' />";

}

But it's not possible with radio buttons. For now it would be enough if I know how to make some code like this real:

<?php if ($some_variable == 'yes')
{echo 'Something';}
?>

Or just <?php echo $some_variable; ?>
But this $some_variable I can't find in my code.

Here is my code in functions.php regarding to radio buttons.

add_settings_field( 'sample_radio_buttons', __( 'Allow triangles in background?', 'YourTheme' ), 'YourTheme_settings_field_sample_radio_buttons', 'theme_options', 'general' );

Creating options for radio buttons field

function YourTheme_sample_radio_button_choices() {

    $sample_radio_buttons = array(

        'yes' => array(

            'value' => 'yes',

            'label' => 'Yes'

        ),

        'no' => array(

            'value' => 'no',

            'label' => 'No'

        ),

    );

    return apply_filters( 'YourTheme_sample_radio_button_choices', $sample_radio_buttons );

}

Creating sample radio buttons field

function YourTheme_settings_field_sample_radio_buttons() {

    $options = YourTheme_get_theme_options();

    foreach ( YourTheme_sample_radio_button_choices() as $button ) {

    ?>

    <div class="layout">

        <label class="description">

            <input type="radio" name="YourTheme_theme_options[sample_radio_buttons]" value="<?php echo esc_attr( $button['value'] ); ?>" <?php checked( $options['sample_radio_buttons'], $button['value'] ); ?> />

            <?php echo $button['label']; ?>

        </label>

    </div>

    <?php

    }

}

Getting the current options from the database and setting deafaults.

function YourTheme_get_theme_options() {

        $saved = (array) get_option( 'YourTheme_theme_options' );

        $defaults = array(

            'sample_checkbox'       => 'off',

            'sample_text_input'     => '',

            'sample_select_options' => '',

            'sample_radio_buttons'  => 'yes',

            'sample_textarea'       => '',

        );

        $defaults = apply_filters( 'YourTheme_default_theme_options', $defaults );

        $options = wp_parse_args( $saved, $defaults );

        $options = array_intersect_key( $options, $defaults );

        return $options;

    }

Then there is a little bit more code about sanitization and validation but I think it should not have any inffluence on variable in form.

Thank you in advance.

On the frontend you can just use the same function as the one you're using in your get_theme_options function, namely:

get_option( 'YourTheme_theme_options' );

Have a look at this: http://codex.wordpress.org/Function_Reference/get_option
