Custom meta boxes for HTML and CSS fields

[scotcrop]

Added custom meta box for HTML and CSS fields below post body. Saves time and gives more room to enter HTML and CSS by default rather than having to create each field with each new post.

Added the following to functions.php to make the html and css fields already have meta boxes rather than creating them for each post in the custom fields area. Screen shot below code.

add_action( 'add_meta_boxes', 'pears_add_meta_box' );
add_action( 'save_post', 'pears_save_post' );

function pears_add_meta_box() {

    add_meta_box( 
        'pears',
        'Pears',
        'pears_meta_box',
        'post',
        'normal',
        'high'
    );

}

function pears_meta_box( $post ) {
    wp_nonce_field( plugin_basename( __FILE__ ), 'pears_noncename' );

    $html = get_post_meta($post->ID,'html',true);
    $css = get_post_meta($post->ID,'css',true);

    echo '<p>These fields are for the HTML markup and CSS styles.  The post body can be used for notes.</p>';
    echo '<label for="html">HTML</label>';
    echo '<p><textarea id="html" name="html" rows="20" cols="90" />' . $html . '</textarea></p>';
    echo '<label for="css">CSS</label>  ';
    echo '<p><textarea id="css" name="css" rows="20" cols="90" />' . $css . '</textarea></p>';
}

function pears_save_post( $post_id ) {

    // Ignore if doing an autosave
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) 
        return;

    // verify data came from pears meta box
    if ( !wp_verify_nonce( $_POST['pears_noncename'], plugin_basename( __FILE__ ) ) )
        return;         

    // Check user permissions
    if ( 'post' == $_POST['post_type'] ) {
        if ( !current_user_can( 'edit_page', $post_id ) )
            return;
    }
    else{
        if ( !current_user_can( 'edit_post', $post_id ) )
            return;
    }

    $html_data = $_POST['html'];
    update_post_meta($post_id, 'html', $html_data);

    $css_data = $_POST['css'];
    update_post_meta($post_id, 'css', $css_data);
}
