The problem: The reason why this isn’t working, is this part of the WP_Embed::shortcode() method: if( $post_ID ) { …. cut … // Use oEmbed to get the HTML $html = wp_oembed_get( $url, $attr ); … cut … } When trying to autoembed with the Heartbeat API the $post_ID is null, so wp_oembed_get() is never … Read more
Are you looking for a filter perhaps? add_filter( ‘the_content’, ‘wpse_the_content_filter’, 20 ); function wpse_the_content_filter( $content ) { // Do whatever you want with the $content return $content; } Filtering ‘the_content’ will pass the post or page content through a function of your choice. Just make sure to run it late (e.g. 20) and return the … Read more
The following bit of code adds a class to the first paragraph output by the_content: function first_paragraph($content){ return preg_replace(‘/<p([^>]+)?>/’, ‘<p$1 class=”intro”>’, $content, 1); } add_filter(‘the_content’, ‘first_paragraph’); Add the above to your theme’s functions.php file. Then in your CSS add something like: p.intro { font-weight:bold; } I can’t claim credit for this solution (see this thread … Read more
You can do this using the ‘the_content’ filter: add_filter( ‘the_content’, ‘insert_featured_image’, 20 ); function insert_featured_image( $content ) { $content = preg_replace( “/<\/p>/”, “</p>” . get_the_post_thumbnail($post->ID, ‘post-single’), $content, 1 ); return $content; } Of course, you can add options to the the_post_thumbnail() function to define which size of thumbnail you’d like to use, etc… http://codex.wordpress.org/Function_Reference/the_post_thumbnail
When in the loop, this will produce excerpt from $post->post_content directly: <?php echo wp_trim_excerpt(); ?> Read more HERE. Alternative Solution: If you are not in the loop, then, you may use similar implementation as done in the wp_trim_excerpt function: $text = strip_shortcodes( $post->post_content ); $text = apply_filters( ‘the_content’, $text ); $text = str_replace(‘]]>’, ‘]]>’, $text); … Read more
What (exactly) happens When calling the_content() inside your template, you are able to call it without any parameters. This means, that the function already has the defaults of null for both arguments: The “more” link text and the boolean switch that allows you to strip teaser content before the “more” link text. The the_content() function … Read more
It is normal for content to be accessed multiple times. For example SEO plugins need to do this to access it and generate meta data from. Also it is a filter hook. Filters should never echo anything to the page, they are meant to modify passed value and return it. If you do want to … Read more
EDIT – Now that 4.4 is out, you should use the content_pagination filter. See birgire’s answer below. You can add formatting to raw post content by applying the content filters directly to $post->post_content: echo apply_filters( ‘the_content’, $post->post_content ); This will bypass pagination by not using the get_the_content function, which is what the_content uses internally to … Read more
Interesting question. This could be a useful part of a specific language file. It cannot be done in CSS, because CSS is (mostly) character agnostic. But using a filter and PHP it is possible and on topic: add_filter( ‘the_content’, ‘t5_chinese_spacing’ ); function t5_chinese_spacing( $content ) { return preg_replace( ‘~([^\p{Han}]*)(\p{Han}+)([^\p{Han}])~imUxu’, ‘\1 \2 \3’, $content ); } … Read more
I ran into this problem a year or so ago, and found a fix here. Open PHP.INI in a text editor of your choice (normally you can find php.ini in your php install dir) Change the recursion limit to 200x normal, that is, set: pcre.recursion_limit=20000000 Change the backtrack limit to 100x normal, that is, set: … Read more
