A shortcode handler doesn’t have to return anything, it can just modify a global variable that you later read in your sidebar widget. If your sidebar is displayed after your post content (most likely if it’s a right sidebar), you can do this without any problem. If your sidebar is displayed before the post content … Read more
Are you going to put newlines in there between each image? or just spaces? I’ll put in both for this example, checking if there’s a newline. You would want something like this in your functions.php: add_shortcode(‘my_gallery’, ‘gallery_function’); function gallery_function($atts, $code=””){ $files=preg_split( ‘/\s+/’, $code ); // Added in from Jan’s comment. foreach($files as $img){ if($img==””) continue; … Read more
you can always just set a css tag display:none to the caption element
That’s the best I can come up with: function wpse20389_show_shortcode_tags() { echo ‘<pre>Shortcode Tags: ‘; print_r( $GLOBALS[‘wp_filter’][‘the_content’] ); echo ‘</pre>’; } add_action( ‘shutdown’, ‘wpse20389_show_shortcode_tags’ );
Try this: // replaces [banner …] .. [/banner] with <!–banner ID–> before the_content filters run add_filter(‘the_content’, ‘protect_my_shortcode’, -100); function protect_my_shortcode($content){ return preg_replace_callback(‘/\[(banner)\b(.*?)(?:(\/))?\](.+?)\[\/\1\]/s’, ‘protect_my_shortcode_callback’, $content); } function protect_my_shortcode_callback($matches){ global $__banners; $id = ‘<!–banner ‘.count($__banners).’–>’; $__banners[$id] = do_shortcode($matches[0]); // or ‘[‘.$matches[1].’ ‘.$matches[2].’]’.$matches[4].'[/’.$matches[1].’]’ // if you need to run any filters on the shortcode content ($matches[4]) return $id; … Read more
You are correct in your thinking that because the loop evaluates after the header you will not be able to get the contents of the loop there. The easiest way to do this is probably with jQuery. Something like this: <script type=”text/javascript”> $(document).ready(function() { document.title=”blah”; }); </script> Place this code in your loop, and the … Read more
There’re two functions: is_user_logged_in() && current_user_can(‘capability_type’) that will help you to acchieve this.
Short answer: no. Shortcodes are for injecting content directly in the Post Content, by the user, via the Post Edit screen. If your data are coming from a metabox, you have other, better, more efficient, and easier-to-control means of injecting content into the Post Content: primarily, the the_content filter (for general usage), or custom action … Read more
How about this? <?php function btn($atts, $content = null) { extract(shortcode_atts(array(‘link’ => ‘#’, ‘color’ => ‘teal’ , ‘size’ => ‘large’), $atts)); return ‘<a class=”btn ‘.$size.'” href=”‘.$link.'” style=”background:’.$color.’;”><span>’ . $content . ‘</span></a>’; } add_shortcode(‘btn’, ‘btn’); ?>
I wasn’t able to replicate your problem exactly, but here’s a tip: include some default behavior, in case the user puts in a bad value for the subject: // Set image acorring to guide type if ($subject == ‘wordpress’) { $subjectImg = ‘<img src=”‘.get_bloginfo(‘template_url’).’/img/postInfoBox/wordpress.png” alt=”מדריך וורדפרס” />’; } elseif ($subject == ‘web design’) { $subjectImg … Read more
