add_shortcode() may be overwritten, dependent upon at what point it is hooked, whereas you would have to remove_filter() to prevent the filter from executing. I think the way to go is to use apply_filters(), as that functionality is clearly put in place to do exactly what you’re trying to do.
You have to return html instead of echoing it. Buffer output withing your function and return it: function shortcode_output() { ob_start(); //get stuff from database //format stuff echo <<<FORM <form method=”POST” action=”blah.php”> <!–more html–> </form> FORM; $html = ob_get_contents(); ob_end_clean(); return $html; }
use do_shortcode($content) instead of $content in first function(collapsegroup)
Find the line /* Remove in-line styling in function.php. Comment out: /* add_shortcode(‘wp_caption’, ‘fixed_img_caption_shortcode’); add_shortcode(‘caption’, ‘fixed_img_caption_shortcode’); function fixed_img_caption_shortcode($attr, $content = null) { // Allow plugins/themes to override the default caption template. $output = apply_filters(‘img_caption_shortcode’, ”, $attr, $content); if ( $output != ” ) return $output; extract(shortcode_atts(array( ‘id’=> ”, ‘align’ => ‘alignnone’, ‘width’ => ”, ‘caption’ … Read more
No Need for SQL queries in the template. function wpse_72594_get_attachments( $id, $mime=”” ) { $args = array( ‘post_type’ => ‘attachment’, ‘post_mime_type’ => $mime, ‘post_parent’ => $id ); $attachments = get_posts($args); if ($attachments) return $attachments; return false; } Then call the function like this (300 is the post ID): wpse_72594_get_attachments(300), grabs all attachments wpse_72594_get_attachments(300, ‘image’ ), … Read more
First of all, you’re using extract / shortcode_atts in correctly: The line: extract(shortcode_atts(array( “li” => get_option(‘li’), ), $liatts)); uses shortcode_atts and then extracts turns each key in the returnarray into its own variable: e.g. $li in this example. But you then go onto use $liatts anyway – which is just the attributes passed from the … Read more
In single.php i put this code, from this link (thank you Wyck) https://stackoverflow.com/questions/14277794/wordpress-3-5-own-gallery-with-included-images-doesnt-work preg_match(‘/\/’, $post_content, $ids); $array_id = explode(“,”, $ids[1]); print_r($array_id); Now I can use gallery shortcode
explode will be your best option. WordPress has a few built in functions to handle arrays of function arguments (wp_parse_args and shortcode_atts for example), but nothing relating to splitting a string and iterating the result. It’s not entierly clear to me what you are trying to achieve, but let’s say you were trying to get … Read more

Apparently you are simply not translating your logic into code: if it has shortcode, do this, if not has shortcode but has thumbnail, do that, otherwise, do something else. if ( wpsite_has_topwide_shortcode() ) { echo ‘shortcode’; } elseif( has_post_thumbnail() ) { echo get_the_post_thumbnail( $post->ID, ‘full’ ); } else { echo ‘Hello World’; }
