If you’re printing your script inline (i.e. not in an external file), you can use PHP to dynamically output the JavaScript argument: <script> _gaq.push( ‘setCustomVar’, 3, ‘pubDate’, ‘<?php the_time( ‘Ym’ ) ?>’, 3 ); </script> See the PHP manual for date arguments, which will explain why I’ve used Ym.
Couple of things – avoid query_posts, use a new query object or the get_posts function (read all about it). And the_ID() echo’s the ID, use get_the_ID() instead. However, you can save some memory and processing by simply iterating over an array of posts (i.e. not using a proper “loop” and setting up the global post), … Read more
do_shortcode([espro-slider id=21]) will process the shortcode and return the result. The Codex describes exactly this example: // Use shortcode in a PHP file (outside the post editor). echo do_shortcode( ” ); You can often just call the callback directly also: function generic_shortcode_callback($atts,$content) { return “Yay! “.$content; } echo generic_shortcode_callback(”,’ Me!’); VS: function generic_shortcode_callback($atts,$content) { return … Read more
actions do not “return” values. If you need to do some heavy computation that you want to avoid redoing at a later stage then you should store the value at a global variable (pure global, static or a field in an object depending on your favorite coding style).
I think you are on the right track, but that last part is messy. You are using the bw_add_markup_class function for two different purposes : to return the classes that you want to add to list the context of the filters that you want to call If I understand well want you are trying to … Read more
WordPress theme files are called thru functions/classes, so variables declared in functions.php are not recognized by other theme files, until you specify you want to use the global value of the variable. Do so like this in your theme template files: global $mysite_address_url; you can then use $mysite_address_url as you’d like. To read more about … Read more
The “cat” variable need to be an ID of the category. It depends how you configured the ACF field in the backend. Maybe you should print_r($selected_cat) to see what’s inside the variable. it is probably an array with the full information of the category.
I’m not exactly sure what you’re trying to accomplish but this won’t work because your trying to use or call the function that is declared in the parent theme instead of replacing it with a new function. I’m not sure if replacing a function in the child theme would work either. Maybe someone else can … Read more
This is that classic question, do you have 6 eggs or half a dozen, and frankly, it doesn’t actually matter. It is however better to use get_comments_number() because the post object is retrieved from the $GLOBALS[‘post’] global which is set by the_post() inside the loop the post object is validated through WP_Post (through get_post()) the … Read more
You can you wp_parse_args to merge $instance with a default array. So, you would start you form function not with extract($instance) but with $defaults = array( ‘title’ => ‘Your title’, ‘text’ => ‘…’, ‘image_url’ => ‘…’ ‘textarea’ => ‘…’ ); $instance = wp_parse_args((array) $instance, $defaults);
