Setting different static WordPress home pages for different themes

Posted on by

You can get WordPress to use a different theme to different visitors to your site. For example, serving up a mobile theme for visitors using a phone. Well, perhaps you want to alter some of the WordPress settings too, like displaying an alternative homepage.

Here’s a bit of code that shows either your blog posts, or a specific static home page depending on which theme is active.

global $static_theme_name;
$static_theme_name = 'Twenty Twelve';
add_filter( 'pre_option_show_on_front', 'tcb_pre_option_show_on_front' );
function tcb_pre_option_show_on_front( $false ){
  global $static_theme_name;
  $theme = wp_get_theme();
  if( $theme->name == $static_theme_name ):
    return 'page';
  endif;

  return 'posts';
}

add_filter( 'pre_option_page_on_front', 'tcb_pre_option_page_on_front' );
function tcb_pre_option_page_on_front( $false ){
  global $static_theme_name;
  $theme = wp_get_theme();
  if( $theme->name == $static_theme_name ):
    return 30;
  endif;

  return false;
}

This bit of code either needs to go in a plugin, or it can be put in both theme’s functions.php. Change the theme name as required.

My WordPress Plugins 2013 – The Good, The Going, The Gone

Plugins are an ever-moving thing in WordPress. As the internet and WordPress core evolves and moves on, so WordPress plugins come and go. About 18 months ago I blogged about The Life And Times of WordPress Plugins. This is a follow up, of sorts, looking back at my plugin usage, and trying to predict my future use.

Those That Were

Media Tags – http://wordpress.org/extend/plugins/media-tags/

This was a real must-have for my work. We have to use cases for media items: being able to group them and attaching meta data to them. A trivial example would be a list of sponsor logos with links to their websites. It now doesn’t get used that much. WordPress core has added the ability to assign taxonomies to attachments. And our sponsors data has grown more complex and become a custom post type. It may continue to fill a niche, but I think that much like scissors it has done the best it can: inspired WordPress core to improve.

Those That Are

Posts 2 Posts – http://wordpress.org/extend/plugins/posts-to-posts/

I just can’t live without this plugin. I use it to create complex profiles for users. Lets say you want your speakers to be able to login and update their profile? Easy, use P2P to link a WordPress user to any number of speaker profiles. Now you have separation and control over the auth credentials and the profile data. Really useful. Now you want to assign your speaker profiles to a bunch of seminars. These relationship can be defined, built and controlled programmatically.

Gravity Forms – http://www.gravityforms.com/

Not a free plugin! But I lost count of how much time (and money!) this has saved me (and therefore those that pay me). There some things about it that rather rub me the wrong way, but life without it would be full of boring manual form building. I have used other form plugins in the past, but they broke too easily. Being able to export and import forms seamlessly is a must.

Those That Will Be

Meta Box – http://wordpress.org/extend/plugins/meta-box/

A great compliment plugin to posts 2 posts. Being able to easily add custom fields to custom post types quickly and easily is not only just plain useful, but really speeds up development time. It is still quite clunky in places. I foresee that it will become slicker. And is possibly even a contender for being considered for absorption into WordPress core. With the emphasis on post formats in WordPress 3.6, and the implied requirement of different input fields based on type of some sort, I can see the attachment of meta data to varying post types being standardised.

 

WordPress – how to get the slug of your post or page?

Finding out the slug for a page or post is one of the most popular search terms on this blog. I find it a little bizarre that my little function generates so much interest, but that’s just one of the unexpected joys of blogging.

I have decided to follow-up my first post on getting the post slug, taking in to consideration the comments and main use of the function. Hopefully, though a small change, it is an improvement.

I’ve split it into two functions. The first forming the base for the second.

Function: get_the_slug()

function get_the_slug( $id=null ){
  if( empty($id) ):
    global $post;
    if( empty($post) )
      return ''; // No global $post var available.
    $id = $post->ID;
  endif;

  $slug = basename( get_permalink($id) );
  return $slug;
}

WordPress appears to be adopting the style of having get_ and the_ function prefixes to get or display content. So here is the complimentary function. I’ve removed some hooks that I don’t think anyone used, instead just applying one (well named) filter.

Function: the_slug()

/**
 * Display the page or post slug
 *
 * Uses get_the_slug() and applies 'the_slug' filter.
 */
function the_slug( $id=null ){
  echo apply_filters( 'the_slug', get_the_slug($id) );
}

Example use of the_slug() and get_the_slug() functions:

<div id="some-post-container-<?php echo get_the_slug(); ?>">
  The post slug is <strong><?php the_slug(); ?></strong>.
  Lorem whatsit here
</div>

How to get a list of all your Gravity Forms

Posted on by

Forms, forms, forms. Probably the primary way for website visitors to submit information to website owners. They let us capture data for all sorts of things. So, unsurprisingly, I’ve doing a lot with forms recently. My go-to WordPress form manager is Gravity Forms.

Sometimes I add functionality that isn’t really an extension of Gravity Forms, but does relate to specific form. All I need is a simple dropdown of the forms, with their ID and title.

$select = '<select>';
$forms = RGFormsModel::get_forms( null, 'title' );
foreach( $forms as $form ):
  $select .= '<option id="' . $form->id . '">' . $form->title . '</option>';
endforeach;
$select .= '</select>';

echo "GF dropdown: $select";

Above is a trivial example to create a dropdown select field.
