yeah, the question is a bit unclear. but i think you need shortcode attributes function get_custom_field_fn( $atts) { global $post; extract( shortcode_atts( array( ‘meta’ => ” ), $atts ) ); $custom_field_value = get_post_meta($post->ID, $meta, true); return $custom_field_value; } add_shortcode(‘cf_name’, ‘get_custom_field_fn’); see the codex: http://codex.wordpress.org/Shortcode_API#Attributes
This looks like a custom function. It’s passing $count to a function called array_pick() to limit the size of your follower array. It also looks like array_pick() is a custom function. But you can easily stop the function from limiting your count by removing the call to array_pick(): function get_random_followers($userid, $count = 10){ $followers = … Read more
When developing locally, always set the following in your wp-config.php to see all errors: // DEBUG error_reporting( E_ALL ); /** Php error log */ @ini_set( ‘log_errors’, ‘On’); @ini_set( ‘display_errors’, ‘On’); define( ‘WP_DEBUG’, true ); define( ‘SAVEQUERIES’, true ); // file: /core_root/content/debug.log define( ‘WP_DEBUG_LOG’, true ); define( ‘WP_DEBUG_DISPLAY’, true );

You need to set paged or an offset in your query, otherwise you’re always fetching the same 48 posts. $page = (get_query_var(‘page’)) ? get_query_var(‘page’) : 1; $args = array( ‘paged’ => $page, ‘posts_per_page’ => ’48’, ‘cat’ => ‘4’, ‘meta_query’ => array( array( ‘key’ => ‘Country’, ‘value’ => $country_search_array, ‘compare’ => ‘IN’ ) ) ); $gallery_query … Read more
is_single() is a function returning a boolean value. You could simply use it for your conditional check rather than passing the global variable. Other than that, your first line of code should be setting $my_global_var with a single equal sign, i.e.: $my_global_var = true;.
It sounds like your opening <?php tag is abutting your first call to update_option. If it isn’t directly adjacent to it, perhaps the whitespace between the two is unrecognized for one reason or another (this can happen from copying and pasting from some sources). Have your functions.php file start off like this: <?php update_option(‘siteurl’,’http://example.com/blog’); update_option(‘home’,’http://example.com/blog’);
Try this instead: function has_shortcode($shortcode=””) { global $post; // false because we have to search through the post content first $found = false; // if no short code was provided, return false if ( !$shortcode ) { return $found; } if ( is_object( $post ) && stripos( $post->post_content, ‘[‘ . $shortcode ) !== false ) … Read more
