customizability to developers through filters.
<h3>Available Routes</h3>

<li><code>/wp-json/arha/v1/page</code></li>
<li><code>/wp-json/arha/v1/options</code></li>
<li><code>/wp-json/arha/v1/archive</code></li>
</ul>
<h3>Example queries</h3>
<ul>
<li><code>/wp-json/arha/v1/post?post_type=POST_TYPE&slug=SLUG</code></li>
<li><code>/wp-json/arha/v1/page?path=PATH</code></li>
<li><code>/wp-json/arha/v1/options</code></li>
<li><code>/wp-json/arha/v1/archive?post_type=POST_TYPE&posts_per_page=POSTS_PER_PAGE&paged=PAGED&orderby=ORDERBY&order=ORDER</code></li>
</ul>
<h3>tax_query and meta_query in archive-route</h3>
<ul>
<li><code>tax_query</code> and <code>meta_query</code> are supported and they work how the query is built for it in <code>new WP_Query()</code></li>
<li>both needs their values to bes passed in as stringified json</li>
</ul>
<h3>Multiple post_types in archive-route</h3>
<ul>
<li>To pass multiple post_types in archive-route, use syntax that lets PHP read GET-param as an array. https://stackoverflow.com/a/9547490</li>
</ul>
<h3>Filters</h3>
<ul>
<li>
To exclude querying specific post types from <code>post</code>– and <code>archive</code>-routes, you 
can use following filters:
` 
add_filter(‘arha_routes/archive_excluded_post_types’, ‘exclude_post_types’); 
add_filter(‘arha_routes/post_excluded_post_types’, ‘exclude_post_types’);
</li>
</ul>
function exclude_post_types($excluded_post_types) { 
 $excluded_post_types = [‘post’]; 
 return $excluded_post_types; 
} 
 `
<ul>
<li>To format <code>post</code>-route’s post before it’s served to client, use <code>arha_routes/format_post</code>-filter 
` 
add_filter(‘arha_routes/format_post’, ‘format_post’);</li>
</ul>
function format_post($post) { 
 return $post; 
} 
 `
<ul>
<li>To format <code>page</code>-route’s post before it’s served to client, use <code>arha_routes/format_page</code>-filter 
` 
add_filter(‘arha_routes/format_page’, ‘format_page’);</li>
</ul>
function format_page($page) { 
 return $page; 
} 
 `
<ul>
<li>
To format <code>archive</code>-route’s posts before they are served to client, use <code>arha_routes/format_archive_post</code>-filter
<code>add_filter('arha_routes/format_archive_post', 'format_archive_post'); 
function format_archive_post($post) { 
return $post; 
}</code>
</li>
<li>
<code>options</code>-route returns empty result by default. To add content to it, use <code>arha_routes/format_options</code>-filter 
` 
add_filter(‘arha_routes/format_options’, ‘format_options’);
</li>
</ul>
function format_options($options) { 
 return $options; 
} 
 `
<ul>
<li>
By default Arha Routes returns only published content with post-, page- and archive-route, this can be modified by adding following filters. 
` 
// for archive route 
add_filter(‘arha_routes/allowed_post_statuses_archive’, ‘allowed_post_statuses’); 
// for post route 
add_filter(‘arha_routes/allowed_post_statuses_post’, ‘allowed_post_statuses’); 
// for page route 
add_filter(‘arha_routes/allowed_post_statuses_page’, ‘allowed_post_statuses’); 
function allowed_post_statuses($post_statuses) { 
// … change post_statuses array
return $post_statuses; 
} 
` 
After adding setting up these filters, request can include “post_status” parameter and it will be compared to $post_statuses array.
</li>
</ul>
<h3>SearchWP</h3>
Arha Routes supports SearchWP-plugin, which lets WP users to make keyword search engine for their content.
Activating SearchWP-plugin adds optional keyword-search functionality to <code>archive</code>-route. This is done by adding <code>s=KEYWORD</code> to the route 
– Example: <code>/wp-json/arha/v1/archive?post_type=products&posts_per_page=10&paged=1&orderby=date&order=ASC&s=monitor</code>
<h3>Polylang</h3>
Arha Routes supports Polylang-plugin, which allows users to create content in multiple languages.
Activating Polylang changes how endpoints work:
<ul>
<li>All routes require additional <code>lang</code>-param
<ul>
<li>Example: <code>/wp-json/arha/v1/archive?post_type=products&posts_per_page=10&paged=1&orderby=date&order=ASC&lang=en</code></li>
</ul>
</li>
<li><code>page</code>-route doesn’t support language prefix in path
<ul>
<li>Example: Permalink <code>/zh/info</code>, use like this <code>/wp-json/arha/v1/page?path=/info&lang=zh</code></li>
<li>Example: Permalink <code>/en/info/test</code>, use like this <code>/wp-json/arha/v1/page?path=/info/test&lang=zh</code></li>
</ul>
</li>
<li><code>options</code>-route passes <code>lang</code>-param forward to <code>arha_routes/format_options</code>-filter 
<code>add_filter('arha_routes/format_options', 'format_options', 10, 2); 
function format_options($options, $lang) { 
return $options; 
}</code></li>
</ul>
<h3>Polylang + SearchWP</h3>
In order to make these two plugins work together, you need to add extra plugin to WP installation.
