Method #1 If available, I would use the: shortcode_atts_{$shortcode} filter to collect the attributes of a given shortcode. Example: $text=” “; $out = wpse172275_get_all_attributes( ‘gallery’, $text ); print_r( $out ); with the output: Array ( [0] => [1] => Array ( [ids] => 1,2 https://wordpress.stackexchange.com/questions/172275/extract-attribute-values-from-every-shortcode-in-post => file ) [2] => Array ( [ids] => 3 … Read more
Is it Ok? Yes! Is it Optimal? No What Would Be Better? Shortcodes map on to PHP functions, so why not cut out the middle man and go straight to the original function? Are there any other downsides? Yes! That shortcode had to come from somewhere, now you have a dependency, maybe the plugin that … Read more
Use this instead of the line in wich you define $days (your second line): $transient = get_transient( ‘your_transient_key’ ); if( !$transient ): $days = file_get_contents( ‘json_file’ ); set_transient( ‘your_transient_key’, $days, DAY_IN_SECONDS*7 ); else: $days = $transient; endif; $days = json_decode( $days ); … May be a bit rough but you get the idea.
You can hijack the shortcode handler and set the attribute to a value of your choice. Then call the native callback for this shortcode. add_shortcode( ‘gallery’, ‘file_gallery_shortcode’ ); function file_gallery_shortcode( $atts ) { $atts[‘link’] = ‘file’; return gallery_shortcode( $atts ); }
I usually apply the_content filters to $content to do this. I think you can aslo use do_shortcode($content); // Column ShortCode Description function column_scdescription($atts, $content=”null”) { return ‘<div class=”description”>’ .apply_filters(‘the_content’, $content) . ‘</div> <!– description ends here –>’; } add_shortcode (“product-description”, “column_scdescription”); Read up on Nested Shortcodes in the codex.
Does your form have an input with the name “name”? For example: <input type=”text” name=”name”> If so, that will cause trouble. Change the name value. Also see: Form ‘name’ breaks and goes to 404 page.
Can I strip HTML tags in the “Compare Revisions” screen?
Maybe try replacing . do_shortcode($content) . with .$content. ? Source: http://wp.smashingmagazine.com/2009/02/02/mastering-wordpress-shortcodes/
This is frustrating issue as I can’t depend on the content editors to be savvy enough with WordPress / HTML to understand how the text they input will be parsed… –EDIT– Having thought of this a bit more I have reconsidered my earlier answer. HTML5+ comes with the Tidy extension, if you are able to … Read more
before you register your shortcode, add the filter to the content for unautop: add_filter( ‘the_content’, ‘shortcode_unautop’ ); Do this also for the areas, maybe excerpt or widget, when your shortcode add to this areas.
