I’ll answer your question below, but have you looked at using embeds? Look here for more information: http://codex.wordpress.org/Embeds The simplest regex for this would look something like http\:\/\/.*\b Here’s an example of it in action: <?php $file=”test.txt”; $fp = fopen($file, ‘r’); $contents = fread($fp, filesize($file)); $matches = array(); preg_match_all(‘/http\:\/\/.*\b/’, $contents, $matches); print_r($matches); ?> Where the … Read more
The task It’s not as easy, as it looks at a first glance. The main problem is, that you can define your own shortcode and simply override the default. Actually that’s what some themes are doing (blame you ThemeForest authors!). In this case, simply hooking into post_gallery won’t work in every case. Drawbacks for post_gallery … Read more
What add_rewrite_tag()’s RegEx matches against?
The filters you are trying to use run on image insertion, so it is not possible to swap all the images already present in your posts using these filters. It should work, however, if you intend to change to img tags from now on. The filter the_content, however, is applied to the post after it … Read more
Regex to turn embedded images in to attachments
Where is this string located ? I know you wrote “without wordpress system” , but WordPress has a function get shortcode regex If you really want to avoid it for some reason, the following example might help you : // check the post for a short code function check_shortcode( $shortcode = NULL ) { $post_to_check … Read more
Two points: Your rule isn’t particularly specific. For numeric matches you should be specific about it and specify a) digits and b) how many digits. Year would be ([0-9]{4}), month/day would be ([0-9]{1,2}). You can’t do it with one rule. Add three separate rules instead. add_rewrite_rule( ‘whats-on/([0-9]{4})/?$’, ‘index.php?page_id=71&event_year=$matches[1]’,’top’); add_rewrite_rule( ‘whats-on/([0-9]{4})/([0-9]{1,2})/?$’, ‘index.php?page_id=71&event_year=$matches[1]&event_month=$matches[2]’,’top’); add_rewrite_rule( ‘whats-on/([0-9]{4})/([0-9]{1,2})/([0-9]{1,2})/?$’, ‘index.php?page_id=71&event_year=$matches[1]&event_month=$matches[2]&event_day=$matches[3]’,’top’);
You can use the function get_posts to get all your post, and then use a foreach cycle to replace the img tags using the regex you posted and then use wp_update_post to change post content: function remove_images_form_past_posts() { if ( get_transient(‘images_removed_from_past’) ) return; $posts = get_posts(‘nopaging=1’); if ( $posts ) { foreach ( $posts as … Read more
I read your question differently than @eric-holmes. It sounds to me like your shortcode needs to function normally under most circumstances but that you are extracting information in special circumstances. Shortcode regex is tricky. Let WordPress do it for you. $pattern = get_shortcode_regex(); preg_match_all(“/$pattern/”,$wp_content,$matches); Your attributes for any shortcodes present in $wp_content should now be … Read more
I think you are talking about a rare scenario. “font-awsome” is the expected name that all plugins and themes should be using as handle. If the developer has not changed the source code of font awsome CSS file, there is no reason to change the name of the handle. Anyway, you can check the global … Read more
