+ Urgent job, if you can't start now and work fast until complete, please don't bid. + If you are interested in the job, let's not waste 5+ hours on a reply to a message, let's reply fast. I have a new WP website and need some of the data from the DB in another site. For this we need to create a 7 API's. Is this something you can help with? There are already some API's for this on our old site and they look like this: REGISTER_REST_ROUTE: register_rest_route('faqs', '/v1(?P<lang>)', array( 'methods' => 'GET', 'callback' => __NAMESPACE__ . '\\api_faqs', )); FUNCTION api_faqs: function api_faqs($data) { $faqs = Helper\get_api_faqs($data['lang']); return rest_ensure_response($faqs); } FUNCTION get_api_faqs: function get_api_faqs($lang) { global $sitepress; $sitepress->switch_lang($lang); $faqs = array(); $args = array( 'post_type' => 'knowledgebase', 'numberposts' => -1, 'order' => 'DESC', 'suppress_filters' => 0, 'post_status' => 'publish' ); $posts = get_posts($args); foreach ($posts as $key => $post) { $api_faq = get_field('api_faq', $post->ID); if ($api_faq) { $faqs[] = $post; } } $json_response = []; foreach ($faqs as $key => $faq) { $faqTitle = do_shortcode($faq->post_title); $faqLink = get_the_permalink($faq->ID); $faqContent = html_entity_decode(preg_replace("/%u([0-9a-f]{3,4})/i", "&#x\\1;", urldecode(do_shortcode($faq->post_content))), ENT_QUOTES, 'UTF-8'); // Remove youtube videos (iframe) from the content $faqContent = preg_replace('/<iframe.*?\/iframe>/i', '', $faqContent); // Check if faqContent has links if (preg_match_all('/<a[^>]+href=([\'"])(?<href>.+?)\1[^>]*>/i', $faqContent, $faqContentLinks)) { // loop through all links on current faq article foreach ($faqContentLinks['href'] as $link) { if (strpos($link, '=')) { // isolate the id $id = explode('=', $link)[1]; if (get_the_permalink($id)) { // replace page id or post id with article's permalink $faqContent = str_replace($link, get_the_permalink($id), $faqContent); } } } } if (preg_match_all('/<img[^>]+src=([\'"])(?<src>.+?)\1[^>]*>/i', $faqContent, $faqContentImages)) { // loop through all images of the current faq article foreach ($faqContentImages['src'] as $image) { $url = parse_url($image); // Replace the host with the host of the request $new_url = $url['scheme'] . "://" . $_SERVER["SERVER_NAME"] . $url['path']; $faqContent = str_replace($image, $new_url, $faqContent); } } $faqContentTextOnly = preg_replace('/(\\r\\n){3,}/', "\r\n", strip_tags($faqContent)); $json_response[] = [ 'faqTitle' => $faqTitle, 'faqUrl' => $faqLink, 'faqContent' => $faqContent, 'faqContentTextOnly' => $faqContentTextOnly, ]; } return $json_response; }
