function wpse250308_get_questions() { global $post; if ( preg_match_all(‘/\[question(.*?)\]/’, $post->post_content, $questions ) ) { $questions = array_key_exists( 1 , $questions) ? $questions[1] : array(); // $questions will contain the array of the question shortcodes //Do your stuff } } $post isn’t available before wp. So, you have to hook on it or actions that fires later.
You can use the_content (Click here for more info) hook to change the content while rendering the post/page. This will be triggered when Post is being read from Database. So post content will not be changed in database but only filtered while rendering. add_filter( ‘the_content’, ‘remove_email_and_url_from_post’ ); function remove_email_and_url_from_post( $content ) { // Check if … Read more
You should try changing your WordPress Site URL from Non WWW to WWW (Eg. if your site url is http://example.com then you should edit it from Setting > General > WordPress URL to http://www.example.com I think this will solve your problem.
that was easy to do directly in sql: UPDATE wp_posts SET post_content = replace(post_content,'</div>\r\n\r\n<div id=”postbottom”>’,'</div><div id=”postbottom”>’);
I thought regex search may become critical so html dom parser may help. See the code below (if it helps): <?php $post_content = get_the_content(); $dom = new DomDocument(); $dom->loadHTML($post_content); foreach ($dom->getElementsByTagName(‘a’) as $item) { echo “<a href=”https://wordpress.stackexchange.com/questions/315648/.$item->getAttribute(“href’).” target=”_blank” rel=””. $item->getAttribute(“rel’) .”‘>”. $item->getAttribute(‘title’) .”</a><br />”; } ?>
The problem with your RegEx patterns: /code-examples/(.*) /code-examples/android/(.*) is that they only match when the ending slash (/) is present in the URL; e.g.: # Example 1: $1 is ‘page1’ /code-examples/page1 /code-examples/android/page1 # Example 2: $1 is ” (empty) /code-examples/ /code-examples/android/ # Example 3 # No matches because the ending / is not present. /code-examples … Read more
Since category and page number is dynamic, you can use htaccess and use this sample rewrite rule below: RewriteRule (.*?)/index.(.*?)\.html $1/page/$2/ You can test the regex here – https://htaccess.madewithlove.be/ and I can see that it is working as far as I have tested it. PS: URL Redirections are cached aggresively, you need to clear you … Read more
I think this is what you are looking for if (preg_match(‘@^/((?!blog|tag)[^/]+)/(?:page/)?\d+@’, $_SERVER[‘REQUEST_URI’], $m)) { wp_redirect(“/$m[1]”, 301); } The regexp uses lookahead to make sure that the first match isn’t blog or tag. The ‘[^/]+’ part matches anything that isn’t a forward slash (/). (?:page/)? – Makes an optional match against ‘page/’ \d+ – Match against … Read more
There’s already a function for checking if a post has a shortcode: has_shortcode(): function enqueue_script_if_shortcode_is_detected() { global $post; wp_register_script( ‘leweb-widgets’, get_stylesheet_directory_uri() . ‘/includes/leweb-widgets.php’, ‘1.0’, true ); if ( has_shortcode( $post->post_content, ‘leweb_suggested_events’ ) ) { wp_enqueue_script(‘leweb-widgets’); } } add_action( ‘wp_enqueue_scripts’, ‘enqueue_script_if_shortcode_is_detected’ ); Just keep in mind that checking the post this way: Will not know if … Read more
The replace code is replacing the whole a element content with <a rel=”nofollow”>. Here’s the correction: I used (.+?) between <a and href” and before and after /go/pluto/ to the closing >. Then in the replace, we put $1 $2 $3 etc. to keep them and add rel=”nofollow”. You can check in this test, and … Read more
