Today wordpress 3.0 has been released. Since i started to play with it almost immediately i found some troubles when i was trying to display all the post in the new wordpress custom type into one single page.
The goals:
- I wanted to create a custom template for these custom posts.
- I wanted to create a custom archive template for these custom posts
I found immediately the solution for the first “issue” . WordPress 3.0 templating system would search for a file named single-[custom post type name].php inside the theme directory so i simply copied and pasted the single.php into the new file and made some tiny modifications.
The second goal was a little bit difficult to achieve. I googled it and i found some articles talking about this issue but none of them gave ma an easy and working solution.
So i decided to take some parts from them and make my own solution.
Note: The custom post type name is “androidapps”
I did create a new useless plugin that fixed my issues. the source coude is the following:
/*
Plugin Name: Androidapss
Plugin URI: http://i love you.com
Version: 1.0.78
Description: A very useless plugin
Author: Baccega Andrea
Author URI: http://www.andreabaccega.com
Tags: seo,google,link,optimization
*/
add_filter('rewrite_rules_array','wp_insertMyRewriteRules');
add_filter('query_vars','wp_insertMyRewriteQueryVars');
add_filter('init','flushRules');
add_action("template_redirect",'buch_template_redirect');
// Remember to flush_rules() when adding rules
function flushRules(){
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
// Adding a new rule
function wp_insertMyRewriteRules($rules)
{
$newrules = array();
$newrules['androidapps/feed/(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?&feed=$matches[1]&post_type=androidapps';
$newrules['androidapps/(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?&feed=$matches[1]&post_type=androidapps';
$newrules['androidapps/page/?([0-9]{1,})/?$'] = 'index.php?&paged=$matches[1]&post_type=androidapps';
$newrules['androidapps/?$'] = 'index.php?paged=1&post_type=androidapps';
return $newrules + $rules;
}
// Adding the id var so that WP recognizes it
function wp_insertMyRewriteQueryVars($vars)
{
array_push($vars, 'id');
return $vars;
}
function buch_template_redirect()
{
global $wp;
$muley_custom_types = array("androidapps");
if (in_array($wp->query_vars["post_type"], $muley_custom_types))
{
if ( is_robots() ) :
do_action('do_robots');
return;
elseif ( is_feed() ) :
do_feed();
return;
elseif ( is_trackback() ) :
include( ABSPATH . 'wp-trackback.php' );
return;
elseif($wp->query_vars["name"]):
include(TEMPLATEPATH . "/single-".$wp->query_vars["post_type"].".php");
die();
else:
include(TEMPLATEPATH . "/".$wp->query_vars["post_type"].".php");
die();
endif;
}
}
Well all the trick is done by two functions
- buch_template_redirect
- wp_insertMyRewriteRules
The first one buch_template_redirect would hack the template functions and would tell wordpress to search for
- single-androidapps.php for single posts
- androidapps.php for archive
The second wp_insertMyRewriteRules which is copied from the wordpress codex website would add some rewrite rules to wordpress so he will knows how to route the requests 
.
Now if you navigate through http://www.andreabaccega.com/androidapps you’ll see the archive template dedicated to the posts inside the “androidapps” type.
How would you use my code for your meanings?
Simply create a new plugin with the code above, then replace all those androidapps instances with your custom post type name.
Enjoy
Alcuni giorni fa, forse settimane, ho ricevuto una richiesta di scambio link apparentemente corretta.
Lavorando in stretto contatto con questo target di siti web ho imparato alcune cose nel tempo e sono arrivato a delle conclusioni anche condivise da altri siti del settore che voglio scrivere e condividere quì con chi mi leggerà
