wp_rewrite rule needed for Custom Post Type
I asked a question recently about a problem I have with using a particular "custom post type" post as my static front page. The code I received does work, but not the way it really should.
In looking at this more, I discovered I need to modify wp_rewrite to make this happen.
Here's my questions...
I have want to display a Custom Post Type single post on my front page, by selecting the page from the "Reading Settings" I've managed to add the custom post type to the reading settings so that's not a problem.
My problem is when I select the Custom Post Type from the Reading Settings and set it, the home page now redirects.
Example...
http://example.com redirects to
http://example.com/slug/custom-post-type-post/
I want the home page to simple be http://example.com
This is why I believe I need to add a rewrite rule to make this happen.
I assume I would need first need to query the posts for the specific post type and then add a rewrite rule. My problem is that I'm pretty new to this and I can modify well, but I'm not familiar with what should be done.
PLEASE HELP!

Is it the same problem has here : http://wpquestions.com/question/show/id/2930 ?- 09/06/11 5:24pm
Armand Morin says:Yes, Julian did provide an answer, but as I said, in further investigation, I believe the proper way to accomplish this is with a wp_rewrite. I'm willing to accept any advice or solutions.

5:38pmJulian Lannigan says:Hey Armand,
The only thing you have to do is initialize this class, so add this to your CORE.php
new LoadRewrites();
(be sure to include the class if you put it in a separate file)
Here is a class I reuse to add rewrites to wp:
class LoadRewrites {
public function __construct() {
$this->buildRewrites();
add_filter('rewrite_rules_array', array(&$this, 'addRewrites'));
add_filter('query_vars', array(&$this, 'addQueryVars'));
add_action('wp_loaded', array(&$this, 'flushRules'));
}
public function buildRewrites() {
$newrules = array();
$newrules['/$'] = 'index.php?p='.get_option("page_on_front");
$this->newrules = $newrules;
}
public function addRewrites($rules) {
return $this->newrules + $rules;
}
public function addQueryVars($vars) {
//array_push($vars, 'theCategory');
return $vars;
}
public function flushRules() {
$rules = get_option('rewrite_rules');
foreach ($this->newrules as $rule) {
if (!isset($rules[$rule])) {
global $wp_rewrite;
$wp_rewrite->flush_rules();
return;
}
}
}
}- 09/06/11 5:54pm
Armand Morin says:Julian,
Ok, I'm missing something here. Does this integrate with what we did yesterday? Or should this be added by itself?
Also, do I have to modify something here to set the custom post type? - 09/06/11 5:59pm
Armand Morin says:One more thing... the reason I think it must be a rewrite is that the code you did yesterday works fine if the root is www.example.com but when I tested on my test xampp setup where my url is localhost/sandbox/ it didn't work.

Julian Lannigan says:Hey Armand,
I fixed the issue using redirects. I added this code, replacing the older code, with the following:
class LoadRewrites {
public function __construct() {
$this->buildRewrites();
add_filter('rewrite_rules_array', array(&$this, 'addRewrites'));
add_filter('query_vars', array(&$this, 'addQueryVars'));
add_action('wp_loaded', array(&$this, 'flushRules'));
}
public function buildRewrites() {
$newrules = array();
$frontPost = get_post(get_option("page_on_front"));
$newrules['^$'] = 'index.php?salesletters='.$frontPost->post_name;
$this->newrules = $newrules;
}
public function addRewrites($rules) {
return $this->newrules + $rules;
}
public function addQueryVars($vars) {
//array_push($vars, 'theCategory');
return $vars;
}
public function flushRules() {
$rules = get_option('rewrite_rules');
foreach ($this->newrules as $rule) {
if (!isset($rules[$rule])) {
global $wp_rewrite;
$wp_rewrite->flush_rules();
return;
}
}
}
}
new LoadRewrites(); - 09/06/11 7:36pm
Armand Morin says:Julian,
Sooo close.
The redirect stopped and that looks great. One minor problem. If you click on a NORMAL PAGE now and want to set that as the homepage, you get page not found. - 09/06/11 7:42pm
Julian Lannigan says:Fixed, I changed the rewrite to include the post's type. Here is the corrected code:
class LoadRewrites {
public function __construct() {
$this->buildRewrites();
add_filter('rewrite_rules_array', array(&$this, 'addRewrites'));
add_filter('query_vars', array(&$this, 'addQueryVars'));
add_action('wp_loaded', array(&$this, 'flushRules'));
}
public function buildRewrites() {
$newrules = array();
$frontPost = get_post(get_option("page_on_front"));
$newrules['^$'] = 'index.php?'.$frontPost->post_type.'='.$frontPost->post_name;
$this->newrules = $newrules;
}
public function addRewrites($rules) {
return $this->newrules + $rules;
}
public function addQueryVars($vars) {
//array_push($vars, 'theCategory');
return $vars;
}
public function flushRules() {
$rules = get_option('rewrite_rules');
foreach ($this->newrules as $rule) {
if (!isset($rules[$rule])) {
global $wp_rewrite;
$wp_rewrite->flush_rules();
return;
}
}
}
}
new LoadRewrites(); - 09/06/11 7:46pm

Armand Morin says:Utkarsh,
Thanks the only problem with this is that I won't know the post id, since I'm setting it from the Reading Settings dropdown menu. - 09/06/11 5:58pm

Armand Morin says:This still redirects the homepage to the post type url.
- 09/06/11 6:03pm
Utkarsh Kukreti says:Strange. It doesn't for me on WP 3.3-pre.
- 09/06/11 6:08pm
Armand Morin says:Remember, I'm selecting a Custom Post Type I've added to the Reading List. The homepage is redirecting the CPT url instead of staying on the homepage.

Utkarsh Kukreti says:How did you add CPT to Reading List? (They aren't there by default..)

Armand Morin says:I think you just posted my original code back to me... am I not reading this right? I already have the CPT in the Reading Settings.

Utkarsh Kukreti says:I added.

This might be a simpler approach than a rewrite.
I have assumed that your page option is being set as an id and that you have a file called single-YOUR-CUSTOM-POST-TYPE.php.
Pop this in your functions file:
function my_template_redirect() {
if( is_home() ) {
$post_id = get_option("page_on_front");
query_posts( array( 'p' => $post_id ) );
include_once('single-YOUR-CUSTOM-POST-TYPE.php');
exit();
}
}
add_action('template_redirect','my_template_redirect');
Clearly your if statement could become more complex ie if there are only certain circumstances that you want to show the custom post...

John
