There can be a case that theme implements hooks via do_action(“action_name”) but it’s not forced to bind actual actions to it, as theme’s developers might just did it to make theme more extensible, and in fact never use it inside theme. So you can just bind your own code via add_action(“colormag_before”, “your_function_name”) in a child … Read more
What your asking for can’t be done using shortcodes. <article> isn’t a part of the content, its part of the theme and it ‘contains’ the content. Thus shortcodes cannot modify it or move those tags around. Shortcodes by definition are part of the content, so anything they add on the end is also a part … Read more
Browser resolution is set on the user end. Actually, the window may even be resized after the page has been loaded. Css media queries will deal with that on the user end. So, when the page is generated on the server side, the user window size is unknown and you cannot determine how many words … Read more
Lets first start with a bit of knowledge-base: the_content is this /** * Display the post content. * * @since 0.71 * * @param string $more_link_text Optional. Content for when there is more text. * @param bool $strip_teaser Optional. Strip teaser content before the more text. Default is false. */ function the_content( $more_link_text = null, … Read more
When you develop a theme you can add specific styling per each post type. by default they all use the single.php theme file, but single-{post-type}.php will be used for the specific post type being displayed (for the full template hierarchy – https://developer.wordpress.org/themes/basics/template-hierarchy/#the-template-file-hierarchy) The navigation links like the prev and next ones you are trying to … Read more
Filters should return their content, and not echo it. That is why you see the output in your head as well EDIT I really have no idea why you would want to use require or include in your filter. Here is an example of your filter should be coded add_filter( ‘the_content’, myFunction ); function myFunction( … Read more
previous_post_link and next_post_link both output the link directly, which won’t work in your case because you’re trying to assign the result to a variable. Use get_previous_post_link() and get_next_post_link() instead- function add_pagin( $content ) { if ( is_singular(‘post’) ) { $content .= get_previous_post_link() . get_next_post_link(); } return $content; } add_filter( ‘the_content’, ‘add_pagin’ );
you need to remove the echo from the the_title(). Change this: <h3><?php the_title();?></h3> Source : https://developer.wordpress.org/reference/functions/the_title/
Use this for example in the loop $new_url=”<img src=”http://www.google.nl”; $content = apply_filters(‘the_content’, get_the_content()); $content = preg_replace(“/(<img[^>]*src *= *[\”‘]?)([^\”‘]*)/i”, $new_url, $content);
To me you code looks good, I would recommend adding priority as high as 9999 Heres how : add_filter(‘the_content’, ‘filter_ptags_on_images’, ‘9999’);
