CONTENT-LINK.PHP

Creamos el archivo content-link.php y añadimos el siguiente código:

Este contenido es más sencillo aún. Simplemente mostramos un link o un conjunto de estos.

 

CONTENT-QUOTE.PHP

Creamos el archivo content-quote.php y añadimos el siguiente código:

  1. <?php
  2.  
  3. <?php
  4. /**
  5.  * The default template for displaying content

  65.

  70. <span class="comments-link"><?php comments_popup_link( '<span class="leave-reply">' . __( 'Leave a reply', 'newtheme' ) . '</span>', __( '<b>1</b> Reply', 'newtheme' ), __( '<b>%</b> Replies', 'newtheme' ) ); ?></span>

  74. </footer><!-- #entry-meta -->
  75. </article><!-- #post-<?php the_ID(); ?> -->

Más de lo mismo, lo único que cambia es que aparece un subtítulo indicando que es una cita.

 

CONTENT-STATUS.PHP

Creamos el archivo content-status.php y añadimos el siguiente código:

  1. <?php
  2. /**
  3.  * The template for displaying posts in the Status Post Format on index and archive pages
  4.  *

En este caso se añade la imagen del perfil del autor o avatar para acompañar al contenido.

Cron Job WordPress

WordPress 3.x para desarrolladores: Temas y plantillas, theme-options.php

0

Nuestro tema va tomando poco a poco forma. Hoy vamos a crear el archivo theme-options.php que contendrá toda la lógica de las opciones de administración.

 

THEME-OPTIONS.PHP

Creamos el archivo theme-options.php y añadimos el siguiente código:

  1. <?php
  2.  
  3. /**
  4.  * Properly enqueue styles and scripts for our theme options page.
  5.  *
  6.  * This function is attached to the admin_enqueue_scripts action hook.
  7.  */
  8. function newtheme_admin_enqueue_scripts( $hook_suffix ) {
  9. wp_enqueue_style( 'newtheme-theme-options', get_template_directory_uri() . '/inc/theme-options.css', false, '2011-04-28' );
  10. wp_enqueue_script( 'newtheme-theme-options', get_template_directory_uri() . '/inc/theme-options.js', array( 'farbtastic' ), '2011-06-10' );
  11. wp_enqueue_style( 'farbtastic' );
  12. }
  13. add_action( 'admin_print_styles-appearance_page_theme_options', 'newtheme_admin_enqueue_scripts' );

Esta función añade un archivo css y un archivo javascript a la cabecera al apartado apariencia de la administración de WordPress.

  1. <?php
  2.  
  3. /**
  4.  * Register the form setting for our newtheme_options array.
  5.  *
  6.  * This function is attached to the admin_init action hook.
  7.  *
  8.  * This call to register_setting() registers a validation callback, newtheme_theme_options_validate(),
  9.  * which is used when the option is saved, to ensure that our option values are complete, properly
  10.  * formatted, and safe.
  11.  */
  12. function newtheme_theme_options_init() {
  13.  
  14. register_setting(
  15. 'newtheme_options', // Options group, see settings_fields() call in newtheme_theme_options_render_page()
  16. 'newtheme_theme_options', // Database option, see newtheme_get_theme_options()
  17. 'newtheme_theme_options_validate' // The sanitization callback, see newtheme_theme_options_validate()
  18. );
  19.  
  20. // Register our settings field group
  21. add_settings_section(
  22. 'general', // Unique identifier for the settings section
  23. '', // Section title (we don't want one)
  24. '__return_false', // Section callback (we don't want anything)
  25. 'theme_options' // Menu slug, used to uniquely identify the page; see newtheme_theme_options_add_page()
  26. );
  27.  
  28. // Register our individual settings fields
  29. add_settings_field(
  30. 'color_scheme', // Unique identifier for the field for this section
  31. __( 'Color Scheme', 'newtheme' ), // Setting field label
  32. 'newtheme_settings_field_color_scheme', // Function that renders the settings field
  33. 'theme_options', // Menu slug, used to uniquely identify the page; see newtheme_theme_options_add_page()
  34. 'general' // Settings section. Same as the first argument in the add_settings_section() above
  35. );
  36.  
  37. add_settings_field( 'link_color', __( 'Link Color', 'newtheme' ), 'newtheme_settings_field_link_color', 'theme_options', 'general' );
  38. add_settings_field( 'layout', __( 'Default Layout', 'newtheme' ), 'newtheme_settings_field_layout', 'theme_options', 'general' );
  39. }
  40. add_action( 'admin_init', 'newtheme_theme_options_init' );

Esta función registra la configuración por defecto del tema y añade varios apartados para la administración.

  1. <?php
  2.  
  3. /**
  4.  * Change the capability required to save the 'newtheme_options' options group.
  5.  *
  6.  * @see newtheme_theme_options_init() First parameter to register_setting() is the name of the options group.
  7.  * @see newtheme_theme_options_add_page() The edit_theme_options capability is used for viewing the page.
  8.  *
  9.  * By default, the options groups for all registered settings require the manage_options capability.
  10.  * This filter is required to change our theme options page to edit_theme_options instead.
  11.  * By default, only administrators have either of these capabilities, but the desire here is
  12.  * to allow for finer-grained control for roles and users.
  13.  *
  14.  * @param string $capability The capability used for the page, which is manage_options by default.
  15.  * @return string The capability to actually use.
  16.  */
  17. function newtheme_option_page_capability( $capability ) {
  18. return 'edit_theme_options';
  19. }
  20. add_filter( 'option_page_capability_newtheme_options', 'newtheme_option_page_capability' );

Esta función permite cambiar las opciones del tema. Es obligatorio para controlar los diversos usuarios y roles que tengan acceso.

  1. <?php
  2.  
  3. /**
  4.  * Add our theme options page to the admin menu, including some help documentation.
  5.  *
  6.  * This function is attached to the admin_menu action hook.
  7.  */
  8. function newtheme_theme_options_add_page() {
  9. $theme_page = add_theme_page(
  10. __( 'Theme Options', 'newtheme' ), // Name of page
  11. __( 'Theme Options', 'newtheme' ), // Label in menu
  12. 'edit_theme_options', // Capability required
  13. 'theme_options', // Menu slug, used to uniquely identify the page
  14. 'newtheme_theme_options_render_page' // Function that renders the options page
  15. );
  16.  
  17. if ( ! $theme_page )
  18. return;
  19.  
  20. add_action( "load-$theme_page", 'newtheme_theme_options_help' );
  21. }
  22. add_action( 'admin_menu', 'newtheme_theme_options_add_page' );

Añade la página de opciones de nuestro tema al menú de administración, incluyendo algo de documentación a la ayuda.

  1. <?php
  2.  
  3. function newtheme_theme_options_help() {
  4.  
  5. $help = '<p>' . __( 'Some themes provide customization options that are grouped together on a Theme Options screen. If you change themes, options may change or disappear, as they are theme-specific. Your current theme, Twenty Eleven, provides the following Theme Options:', 'newtheme' ) . '</p>' .
  6. '<ol>' .
  7. '<li>' . __( '<strong>Color Scheme</strong>: You can choose a color palette of "Light" (light background with dark text) or "Dark" (dark background with light text) for your site.', 'newtheme' ) . '</li>' .
  8. '<li>' . __( '<strong>Link Color</strong>: You can choose the color used for text links on your site. You can enter the HTML color or hex code, or you can choose visually by clicking the "Select a Color" button to pick from a color wheel.', 'newtheme' ) . '</li>' .
  9. '<li>' . __( '<strong>Default Layout</strong>: You can choose if you want your site&#8217;s default layout to have a sidebar on the left, the right, or not at all.', 'newtheme' ) . '</li>' .
  10. '</ol>' .
  11. '<p>' . __( 'Remember to click "Save Changes" to save any changes you have made to the theme options.', 'newtheme' ) . '</p>';
  12.  
  13. $sidebar = '<p><strong>' . __( 'For more information:', 'newtheme' ) . '</strong></p>' .
  14. '<p>' . __( '<a href="http://codex.wordpress.org/Appearance_Theme_Options_Screen" target="_blank">Documentation on Theme Options</a>', 'newtheme' ) . '</p>' .
  15. '<p>' . __( '<a href="http://wordpress.org/support/" target="_blank">Support Forums</a>', 'newtheme' ) . '</p>';
  16.  
  17. $screen = get_current_screen();
  18.  
  19. if ( method_exists( $screen, 'add_help_tab' ) ) {
  20. // WordPress 3.3
  21. $screen->add_help_tab( array(
  22. 'title' => __( 'Overview', 'newtheme' ),
  23. 'id' => 'theme-options-help',
  24. 'content' => $help,
  25. )
  26. );
  27.  
  28. $screen->set_help_sidebar( $sidebar );
  29. } else {
  30. // WordPress 3.2
  31. add_contextual_help( $screen, $help . $sidebar );
  32. }
  33. }

Esta es la función que añade la ayuda que comentaba en la función anterior. Aquí además podemos ver como se añade un condicional para añadir retrocompatibilidad con versiones anteriores a la 3.3 y la 3.2.

  1. <?php
  2.  
  3. /**
  4.  * Returns an array of color schemes registered for New Theme.
  5.  */
  6. function newtheme_color_schemes() {
  7. $color_scheme_options = array(
  8. 'light' => array(
  9. 'value' => 'light',
  10. 'label' => __( 'Light', 'newtheme' ),
  11. 'thumbnail' => get_template_directory_uri() . '/inc/images/light.png',
  12. 'default_link_color' => '#1b8be0',
  13. ),
  14. 'dark' => array(
  15. 'value' => 'dark',
  16. 'label' => __( 'Dark', 'newtheme' ),
  17. 'thumbnail' => get_template_directory_uri() . '/inc/images/dark.png',
  18. 'default_link_color' => '#e4741f',
  19. ),
  20. );
  21.  
  22. return apply_filters( 'newtheme_color_schemes', $color_scheme_options );
  23. }

Esta función devuelve un array con los esquemas de color para cada versión del tema.

  1. <?php
  2.  
  3. /**
  4.  * Returns an array of layout options registered for New Theme.
  5.  */
  6. function newtheme_layouts() {
